From 252486a13a36e2846ff046c18aae67658692eced Mon Sep 17 00:00:00 2001 From: Nishant Sarmukadam Date: Thu, 30 Dec 2010 11:23:31 -0800 Subject: mwl8k: Modify add_dma_header to include pad parameters Add capability to add_dma_header to support padding at tail of the data packet to be transmitted when crypto is enabled. Padding is required for adding crypto information in data packets for supporting 802.11 security modes.

While correct according to the documentation, this is causing spurious decryption error reports in some situations. Fix this by restoring the original order of the checks in those places, where the errors are meant to be mutually exclusive. If a CRC error is reported, then MIC failure and decryption errors are irrelevant, and a PHY error is unlikely. Signed-off-by: Felix Fietkau Signed-off-by: John W.

It will always request a max buffer size (which is fine, if a little pointless, as the mac80211 code doesn't know and might just use 0 instead), but if the peer requests a smaller size it isn't possible to honour this request. In order to fix this, look at the buffer size in the addBA response frame, keep track of it and pass it to the driver in the ampdu_action callback when called with the IEEE80211_AMPDU_TX_OPERATIONAL action. That way the driver can limit the number of subframes in aggregates appropriately. Note that this doesn't fix any drivers apart from the addition of the new argument -- they all need to be updated separately to use this variable! Signed-off-by: Johannes Berg Signed-off-by: John W.

A recent rework of enic_set_port_profile added code to reset this flag on disassociate. As a result of which a client calling enic_get_vf_port to get the status of port profile disassociate will always get a return value of ENODATA. This patch renames ENIC_SET_APPLIED to more appropriate ENIC_PORT_REQUEST_APPLIED and reverts back the recent change so that the flag is set both at associate and disassociate of a port profile.

Because there are now overlapping channel numbers in the 2GHz and 5GHz band we can't map from channel to frequency without knowing the band. This is no problem as in most contexts we know the band. In places where we don't know the band (and WEXT compatibility) we assume the 2GHz band for channels below 14. This patch does not implement all channel to frequency mappings defined in 802.11, it's just an extension for 802.11j 20MHz channels. 5MHz and 10MHz channels as well as 802.11y channels have been omitted. The following drivers have been updated to reflect the API changes: iwl-3945, iwl-agn, iwmc3200wifi, libertas, mwl8k, rt2x00, wl1251, wl12xx. The drivers have been compile-tested only.

A typical beacon interval for AP's is 100TU. This leads to a ~30% worst-case probability of finding an AP via passive scanning. For 5GHz bands for DFS frequencies passive scanning is the only scanning option. Hence for these, the probability of finding an AP is very low. To fix this, increase the passive channel scan dwell times (also the early leave value, as 5GHz channels are still typically very silent.) Use a value of 100TU, because that covers most typical AP configurations. Based on testing the probability of finding an AP (100TU beacon interval) on a single scan round are as follows (based on 100 iterations): dwell min/max (TU) | probability ---------------------+------------ 30/60 | 35% 60/60 | 56% 80/80 | 77% 100/100 | 100% Total scan times now and after the change: Region | Before (s) | After (s) -------+------------+---------- 00 | 0.77 | 1.48 FI | 0.95 | 2.01 US | 0.91 | 1.76 Signed-off-by: Juuso Oikarinen Reviewed-by: Luciano Coelho Signed-off-by: Luciano Coelho --- drivers/net/wireless/wl12xx/conf.h | 18 +++++++++--------- drivers/net/wireless/wl12xx/main.c | 4 ++-- 2 files changed, 11 insertions(+), 11 deletions(-) (limited to 'drivers') diff --git a/drivers/net/wireless/wl12xx/conf.h b/drivers/net/wireless/wl12xx/conf.h index 135d837cefb1..fd1dac9ab4db 100644 --- a/drivers/net/wireless/wl12xx/conf.h +++ b/drivers/net/wireless/wl12xx/conf.h @@ -1084,30 +1084,30 @@ struct conf_scan_settings { /* * The minimum time to wait on each channel for active scans * - * Range: 0 - 65536 tu + * Range: u32 tu/1000 */ - u16 min_dwell_time_active; + u32 min_dwell_time_active; /* * The maximum time to wait on each channel for active scans * - * Range: 0 - 65536 tu + * Range: u32 tu/1000 */ - u16 max_dwell_time_active; + u32 max_dwell_time_active; /* - * The maximum time to wait on each channel for passive scans + * The minimum time to wait on each channel for passive scans * - * Range: 0 - 65536 tu + * Range: u32 tu/1000 */ - u16 min_dwell_time_passive; + u32 min_dwell_time_passive; /* * The maximum time to wait on each channel for passive scans * - * Range: 0 - 65536 tu + * Range: u32 tu/1000 */ - u16 max_dwell_time_passive; + u32 max_dwell_time_passive; /* * Number of probe requests to transmit on each active scan channel diff --git a/drivers/net/wireless/wl12xx/main.c b/drivers/net/wireless/wl12xx/main.c index eda2f3d8edf1..e535e79e269d 100644 --- a/drivers/net/wireless/wl12xx/main.c +++ b/drivers/net/wireless/wl12xx/main.c @@ -279,8 +279,8 @@ static struct conf_drv_settings default_conf = { .scan = { .min_dwell_time_active = 7500, .max_dwell_time_active = 30000, - .min_dwell_time_passive = 30000, - .max_dwell_time_passive = 60000, + .min_dwell_time_passive = 100000, + .max_dwell_time_passive = 100000, .num_probe_reqs = 2, }, .rf = { -- cgit v1.2.1 From e5e2f24b3eec67a7a35d43654a997f98ca21aff2 Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Mon, 24 Jan 2011 19:19:03 +0100 Subject: wl12xx: disable auto-arp The auto-arp feature sometimes has unexpected side effects (e.g. firmware crashes, no ARP replies, etc.) disable it until it will be solved.

However we are reading the macversion and revisions only after RTC is powered ON and so both macversion and revisions are actully zero and this leads to incorrect srev checks Incorrect srev checks can cause registers to be configured wrongly and can cause unexpected behavior. Fixing this seems to address the ASPM issue that we have observed. The laptop becomes very slow and hangs mostly with ASPM L1 enabled without this fix. fix this by reading the macversion and revisisons even before we start using them. There is no reason why should we delay reading this info until RTC is powered on as this is just a register information.

At some point in time, it will be replaced by a proper implementation in mac80211. By making the code easier to read and maintain, removing virtual wiphy support helps with fixing the remaining driver issues and adding further improvements.

Most of these ways were wrong. ATH_TXQ_AC_* cannot be used as an index for sc->tx.txq, because it is only used internally for queue assignment. One place used WME_AC_* as a queue index for sc->debug.stats.txstats, however this array uses the ath9k_hw queue number as well. Fix all of this by always using the ath9k_hw queue number as an index, and always looking it up by going through sc->tx.txq_map. Signed-off-by: Felix Fietkau Cc: Ben Greear Signed-off-by: John W.

This keeps the knowledge of regdomains and defines like MKK9_MKKC in one place. I'm passing the regdomain code instead of the ath_regulatory structure because this needs to be called quite early in the driver inititalization where ath_regulatory is not available yet in ath5k. I'm using MKK9_MKKC only because this is the regdomain in the 802.11j enabled sample cards we got from our vendor. I found some hints in HAL code that this is used by Atheros to indicate 4.9GHz channels support and that there might be other domain codes as well, but as I don't have any documentation I'm just putting in what I need right now.

Both ath9k and ath9k_htc were not affected by this change because the opmode is re-initialized after every reset, when RX is started.

Also we need to make sure we don't export more retries than we are configured for to mac80211 (and the rate module) in hw->max_rate_tries.

The only place to start and stop beaconing are now the start- and stop_queue callbacks. Hence, we can remove some register writes during interface bring up (config_intf) and only write the correct sync mode to the register there. When multiple beaconing interfaces are present we should enable beaconing as soon as mac80211 enables beaconing on at least one of them. The beacon queue gets stopped when the last beaconing interface was stopped by mac80211. Therefore, introduce another interface counter to keep track ot the number of enabled beaconing interfaces and start or stop the beacon queue accordingly. To allow single interfaces to stop beaconing, add a new driver callback clear_beacon to clear a single interface's beacon without affecting the other interfaces. Don't overload the clear_entry callback for clearing beacons as that would introduce additional overhead (check for each TX queue) into the clear_entry callback which is used on the drivers TX/RX hotpaths. Furthermore, the write beacon callback doesn't need to enable beaconing anymore but since beaconing should be disabled while a new beacon is written or cleared we still disable beacon generation and enable it afterwards again in the driver specific callbacks. However, beacon related interrupts should not be disabled/enabled here, that's solely done from the start- and stop queue callbacks. It would be nice to stop the beacon queue just before the beacon update and enable it afterwards in rt2x00queue itself instead of the current implementation that relies on the driver doing the right thing. However, since start- and stop_queue are mutex protected we cannot use them for atomic beacon updates.

The bss_info_changed callback and the periodic update triggered by the TBTT or PRETBTT interrupt. Since the next TBTT or PRETBTT interrupt will periodically fetch an updated beacon remove the update_beacon call in the bss_info_changed callback for PCI devices. In the worst case it will take one beacon interval longer to fetch the new beacon then before. For devices that have a PRETBTT interrupt there should be no change at all.

The problem was caused by tx_work, which is scheduled on each TX operation. If the firmware buffer is full, tx_work does nothing. In combinition with stopped queues or non-continues transfers, tx_work is never scheduled again. Moreover the low watermark introduced by 9df86e2e702c6d5547aced7f241addd2d698bb11 never takes effect because of some old code. Solve this by scheduling tx_work every time tx_queue is non-empty and firmware buffer is freed on tx_complete. This also solves a possible but unlikely case: If less frames than the high watermark are queued, but more than firmware buffer can hold.

It appears that when tx-queue is disabled, tx-urbs might be left pending. These can cause ehci to call non-existing tx_urb_complete() (after rmmod) or uninitialized/reseted private structure (after disconnect()). Add skb queue for submitted packets and unlink pending urbs on zd_usb_disable_tx(). Part of the problem seems to be usb->free_urb_list that isn't always working as it should, causing machine freeze when trying to free the list in zd_usb_disable_tx(). Caching free urbs isn't what other drivers seem to be doing (usbnet for example) so strip free_usb_list. Patch makes tx-urb handling saner with use of urb anchors.

The other one is HW_UpdateBcnInterval() that set_aw_pt_bi() appears to be based on. HW_UpdateBcnInterval() takes interval argument as u16 and uses that for calculations, set_aw_pt_bi() uses u32 value that has flags and dtim in upper part. This clearly seems wrong. Also HW_UpdateBcnInterval() updates only lower 16bit part of CR_BNC_INTERVAL. So make set_aw_pt_bi() do calculations on only lower u16 part of s->beacon_interval. Also set 32bit beacon interval register before reading values from device, as HW_EnableBeacon() on vendor driver does. This is required to make beacon work on AP-mode, simply reading and then writing updated values is not enough at least with zd1211b. Signed-off-by: Jussi Kivilinna Signed-off-by: John W.

On non-AP modes this only causes problems for LED updating code but when we are running in AP-mode we are writing new beacon to HW usually every 100ms. Now if control message fails in HW beacon setup, device lock is kept locked and beacon data partially written. This can and usually does cause: 1. HW beacon setup fail now on, as driver cannot acquire device lock. 2. Beacon-done interrupt stop working as device has incomplete beacon. Therefore make zd_mac_config_beacon() always try to release device lock and add beacon watchdog to restart beaconing when stall is detected. Also fix zd_mac_config_beacon() try acquiring device lock for max 500ms, as what old code appeared to be trying to do using loop and msleep(1). Signed-off-by: Jussi Kivilinna Signed-off-by: John W.

However, the clearing of a separate MIC entry with hardware revisions that use combined MIC key layout did not do that with one of the registers. Add the matching register write to the following register to make the KEY4 register write actually complete. This is mostly a fix for a theoretical issue since the incorrect entry that could potentially be left behind in the key cache would not match with received frames. Anyway, better make this code clean the entry correctly using paired register writes. Signed-off-by: Jouni Malinen Signed-off-by: John W.

If the baseband hang occurs, the rx_clear signal will be stuck to high, so we can use the cycle counters to confirm it. With this patch, a hardware reset is only triggered if the baseband hang check returned true three times in a row, with a beacon interval between each check and if the busy time was also 99% or more during the check intervals.

This causes unneeded HW resets and which can cause unneeded LLDP frames and negotiations. The current check is not sufficient because the FCoE priority can change twice during a negotiation which results in the bits being set. This occurs when the switch changes the priority or when the link is reset with switches that do not include the APP priority until after PFC has been negotiated. This results in set_app being called with the local APP priority. Then the negotiation completes and set_app is called again with the peer APP priority. The check fails so the device is reset and the above occurs again resulting in an endless loop of resets. By only resetting the device if the APP priority has really changed we short circuit the loop.

This structure was designed to support the CEE standard and does not match the IEEE standard well. This patch changes the HW routines in ixgbe_dcb_8259x.{ch} to use raw pfc and bandwidth values. This requires some parsing of the DCB configuration but makes the HW routines independent of the data structure that contains the DCB configuration. The primary advantage to doing this is we can do HW setup directly from the 802.1Qaz ops without having to arbitrarily encapsulate this data into the CEE structure.

Bosch C_CAN user manual can be obtained from: http://www.semiconductors.bosch.de/media/en/pdf/ipmodules_1/c_can/users_manual_c_can.pdf This patch adds the support for this controller. The following are the design choices made while writing the controller driver: 1. Interface Register set IF1 has be used only in the current design. 2. Out of the 32 Message objects available, 16 are kept aside for RX purposes and the rest for TX purposes. 3. NAPI implementation is such that both the TX and RX paths function in polling mode.

This patch makes zd_usb_iowrite16v use asynchronous urb submit within zd_usb.c. zd_usb_iowrite16v_async_start is used to initiate writing multiple commands to device using zd_usb_iowrite16v_async. Each URB is delayed and submitted to device by next zd_usb_iowrite16v_async call or by call to zd_usb_iowrite16v_async_end. URBs submitted by zd_usb_iowrite16v_async have URB_NO_INTERRUPT set and last URB send by zd_usb_iowrite16v_async_end does not. This lower CPU usage when doing writes that require multiple URBs.

NOTE: (for users with a custom eeprom binary) I spent some time updating p54tools to support the new format too: => (git available from) http://git.kernel.org/?p=linux/kernel/git/chr/p54tools.git It now comes with a simplistic script "n800_rssi2v2.sh" which can be used to automate the conversion.

Current Solarstorm controllers do not implement TX queue priority, but they do allow queues to be 'paced' with an enforced delay between packets. Paced and unpaced queues are scheduled in round-robin within two separate hardware bins (paced queues with a large delay may be placed into a third bin temporarily, but we won't use that). If there are queues in both bins, the TX scheduler will alternate between them. If we make high-priority queues unpaced and best-effort queues paced, and high-priority queues are mostly empty, a single high-priority queue can then instantly take 50% of the packet rate regardless of how many of the best-effort queues have descriptors outstanding. We do not actually want an enforced delay between packets on best- effort queues, so we set the pace value to a reserved value that actually results in a delay of 0.

At this point, we think that it's best to disable the use of multiple receive queues. The current patch provides an effective means for the same. Also, we continue to disallow multiple hardware transmit queues per device. But change the way we enforce this in order to maintain consistency with the way receive queues are handled.

The - module will be called iwl3945. diff --git a/drivers/net/wireless/iwlwifi/Makefile b/drivers/net/wireless/iwlwifi/Makefile index 25be742c69c9..aab7d15bd5ed 100644 --- a/drivers/net/wireless/iwlwifi/Makefile +++ b/drivers/net/wireless/iwlwifi/Makefile @@ -1,36 +1,23 @@ -obj-$(CONFIG_IWLWIFI) += iwlcore.o -iwlcore-objs := iwl-core.o iwl-eeprom.o iwl-hcmd.o iwl-power.o -iwlcore-objs += iwl-rx.o iwl-tx.o iwl-sta.o -iwlcore-objs += iwl-scan.o iwl-led.o -iwlcore-$(CONFIG_IWL3945) += iwl-legacy.o -iwlcore-$(CONFIG_IWL4965) += iwl-legacy.o -iwlcore-$(CONFIG_IWLWIFI_DEBUGFS) += iwl-debugfs.o -iwlcore-$(CONFIG_IWLWIFI_DEVICE_TRACING) += iwl-devtrace.o - -# If 3945 is selected only, iwl-legacy.o will be added -# to iwlcore-m above, but it needs to be built in. -iwlcore-objs += $(iwlcore-m) - -CFLAGS_iwl-devtrace.o := -I$(src) - # AGN obj-$(CONFIG_IWLAGN) += iwlagn.o iwlagn-objs := iwl-agn.o iwl-agn-rs.o iwl-agn-led.o iwlagn-objs += iwl-agn-ucode.o iwl-agn-tx.o iwlagn-objs += iwl-agn-lib.o iwl-agn-rx.o iwl-agn-calib.o iwlagn-objs += iwl-agn-tt.o iwl-agn-sta.o iwl-agn-eeprom.o -iwlagn-$(CONFIG_IWLWIFI_DEBUGFS) += iwl-agn-debugfs.o -iwlagn-$(CONFIG_IWL4965) += iwl-4965.o -iwlagn-$(CONFIG_IWL5000) += iwl-agn-rxon.o iwl-agn-hcmd.o iwl-agn-ict.o -iwlagn-$(CONFIG_IWL5000) += iwl-5000.o -iwlagn-$(CONFIG_IWL5000) += iwl-6000.o -iwlagn-$(CONFIG_IWL5000) += iwl-1000.o -iwlagn-$(CONFIG_IWL5000) += iwl-2000.o +iwlagn-objs += iwl-core.o iwl-eeprom.o iwl-hcmd.o iwl-power.o +iwlagn-objs += iwl-rx.o iwl-tx.o iwl-sta.o +iwlagn-objs += iwl-scan.o iwl-led.o +iwlagn-objs += iwl-agn-rxon.o iwl-agn-hcmd.o iwl-agn-ict.o +iwlagn-objs += iwl-5000.o +iwlagn-objs += iwl-6000.o +iwlagn-objs += iwl-1000.o +iwlagn-objs += iwl-2000.o + +iwlagn-$(CONFIG_IWLWIFI_DEBUGFS) += iwl-agn-debugfs.o +iwlagn-$(CONFIG_IWLWIFI_DEBUGFS) += iwl-debugfs.o +iwlagn-$(CONFIG_IWLWIFI_DEVICE_TRACING) += iwl-devtrace.o -# 3945 -obj-$(CONFIG_IWL3945) += iwl3945.o -iwl3945-objs := iwl3945-base.o iwl-3945.o iwl-3945-rs.o iwl-3945-led.o -iwl3945-$(CONFIG_IWLWIFI_DEBUGFS) += iwl-3945-debugfs.o +CFLAGS_iwl-devtrace.o := -I$(src) ccflags-y += -D__CHECK_ENDIAN__ diff --git a/drivers/net/wireless/iwlwifi/iwl-3945-debugfs.c b/drivers/net/wireless/iwlwifi/iwl-3945-debugfs.c deleted file mode 100644 index ef0835b01b6b..000000000000 --- a/drivers/net/wireless/iwlwifi/iwl-3945-debugfs.c +++ /dev/null @@ -1,522 +0,0 @@ -/****************************************************************************** - * - * GPL LICENSE SUMMARY - * - * Copyright(c) 2008 - 2010 Intel Corporation.

The rest of - * the steps figure out the proper settings for the device to achieve - * that target txpower. - * - * - * 3) Determine (EEPROM) calibration sub band for the target channel, by - * comparing against first and last channels in each sub band - * (see struct iwl4965_eeprom_calib_subband_info). - * - * - * 4) Linearly interpolate (EEPROM) factory calibration measurement sets, - * referencing the 2 factory-measured (sample) channels within the sub band. - * - * Interpolation is based on difference between target channel's frequency - * and the sample channels' frequencies. Since channel numbers are based - * on frequency (5 MHz between each channel number), this is equivalent - * to interpolating based on channel number differences. - * - * Note that the sample channels may or may not be the channels at the - * edges of the sub band. The target channel may be "outside" of the - * span of the sampled channels. - * - * Driver may choose the pair (for 2 Tx chains) of measurements (see - * struct iwl4965_eeprom_calib_ch_info) for which the actual measured - * txpower comes closest to the desired txpower. Usually, though, - * the middle set of measurements is closest to the regulatory limits, - * and is therefore a good choice for all txpower calculations (this - * assumes that high accuracy is needed for maximizing legal txpower, - * while lower txpower configurations do not need as much accuracy). - * - * Driver should interpolate both members of the chosen measurement pair, - * i.e. for both Tx chains (radio transmitters), unless the driver knows - * that only one of the chains will be used (e.g. only one tx antenna - * connected, but this should be unusual). The rate scaling algorithm - * switches antennas to find best performance, so both Tx chains will - * be used (although only one at a time) even for non-MIMO transmissions. - * - * Driver should interpolate factory values for temperature, gain table - * index, and actual power. The power amplifier detector values are - * not used by the driver. - * - * Sanity check: If the target channel happens to be one of the sample - * channels, the results should agree with the sample channel's - * measurements! - * - * - * 5) Find difference between desired txpower and (interpolated) - * factory-measured txpower. Using (interpolated) factory gain table index - * (shown elsewhere) as a starting point, adjust this index lower to - * increase txpower, or higher to decrease txpower, until the target - * txpower is reached. Each step in the gain table is 1/2 dB. - * - * For example, if factory measured txpower is 16 dBm, and target txpower - * is 13 dBm, add 6 steps to the factory gain index to reduce txpower - * by 3 dB. - * - * - * 6) Find difference between current device temperature and (interpolated) - * factory-measured temperature for sub-band. Factory values are in - * degrees Celsius. To calculate current temperature, see comments for - * "4965 temperature calculation". - * - * If current temperature is higher than factory temperature, driver must - * increase gain (lower gain table index), and vice verse. - * - * Temperature affects gain differently for different channels: - * - * 2.4 GHz all channels: 3.5 degrees per half-dB step - * 5 GHz channels 34-43: 4.5 degrees per half-dB step - * 5 GHz channels >= 44: 4.0 degrees per half-dB step - * - * NOTE: Temperature can increase rapidly when transmitting, especially - * with heavy traffic at high txpowers. Driver should update - * temperature calculations often under these conditions to - * maintain strong txpower in the face of rising temperature. - * - * - * 7) Find difference between current power supply voltage indicator - * (from "initialize alive") and factory-measured power supply voltage - * indicator (EEPROM). - * - * If the current voltage is higher (indicator is lower) than factory - * voltage, gain should be reduced (gain table index increased) by: - * - * (eeprom - current) / 7 - * - * If the current voltage is lower (indicator is higher) than factory - * voltage, gain should be increased (gain table index decreased) by: - * - * 2 * (current - eeprom) / 7 - * - * If number of index steps in either direction turns out to be > 2, - * something is wrong ... just use 0. - * - * NOTE: Voltage compensation is independent of band/channel. - * - * NOTE: "Initialize" uCode measures current voltage, which is assumed - * to be constant after this initial measurement. Voltage - * compensation for txpower (number of steps in gain table) - * may be calculated once and used until the next uCode bootload. - * - * - * 8) If setting up txpowers for MIMO rates (rate indexes 8-15, 24-31), - * adjust txpower for each transmitter chain, so txpower is balanced - * between the two chains. There are 5 pairs of tx_atten[group][chain] - * values in "initialize alive", one pair for each of 5 channel ranges: - * - * Group 0: 5 GHz channel 34-43 - * Group 1: 5 GHz channel 44-70 - * Group 2: 5 GHz channel 71-124 - * Group 3: 5 GHz channel 125-200 - * Group 4: 2.4 GHz all channels - * - * Add the tx_atten[group][chain] value to the index for the target chain. - * The values are signed, but are in pairs of 0 and a non-negative number, - * so as to reduce gain (if necessary) of the "hotter" channel. This - * avoids any need to double-check for regulatory compliance after - * this step. - * - * - * 9) If setting up for a CCK rate, lower the gain by adding a CCK compensation - * value to the index: - * - * Hardware rev B: 9 steps (4.5 dB) - * Hardware rev C: 5 steps (2.5 dB) - * - * Hardware rev for 4965 can be determined by reading CSR_HW_REV_WA_REG, - * bits [3:2], 1 = B, 2 = C. - * - * NOTE: This compensation is in addition to any saturation backoff that - * might have been applied in an earlier step. - * - * - * 10) Select the gain table, based on band (2.4 vs 5 GHz). - * - * Limit the adjusted index to stay within the table! - * - * - * 11) Read gain table entries for DSP and radio gain, place into appropriate - * location(s) in command (struct iwl4965_txpowertable_cmd). - */ - -/** - * When MIMO is used (2 transmitters operating simultaneously), driver should - * limit each transmitter to deliver a max of 3 dB below the regulatory limit - * for the device.

Do not exceed (saturation - backoff[rate]); + * reduce target txpower if necessary. + * + * Backoff values below are in 1/2 dB units (equivalent to steps in + * txpower gain tables): + * + * OFDM 6 - 36 MBit: 10 steps (5 dB) + * OFDM 48 MBit: 15 steps (7.5 dB) + * OFDM 54 MBit: 17 steps (8.5 dB) + * OFDM 60 MBit: 20 steps (10 dB) + * CCK all rates: 10 steps (5 dB) + * + * Backoff values apply to saturation txpower on a per-transmitter basis; + * when using MIMO (2 transmitters), each transmitter uses the same + * saturation level provided in EEPROM, and the same backoff values; + * no reduction (such as with regulatory txpower limits) is required. + * + * Saturation and Backoff values apply equally to 20 Mhz (legacy) channel + * widths and 40 Mhz (.11n HT40) channel widths; there is no separate + * factory measurement for ht40 channels. + * + * The result of this step is the final target txpower. The rest of + * the steps figure out the proper settings for the device to achieve + * that target txpower. + * + * + * 3) Determine (EEPROM) calibration sub band for the target channel, by + * comparing against first and last channels in each sub band + * (see struct iwl4965_eeprom_calib_subband_info). + * + * + * 4) Linearly interpolate (EEPROM) factory calibration measurement sets, + * referencing the 2 factory-measured (sample) channels within the sub band. + * + * Interpolation is based on difference between target channel's frequency + * and the sample channels' frequencies. Since channel numbers are based + * on frequency (5 MHz between each channel number), this is equivalent + * to interpolating based on channel number differences. + * + * Note that the sample channels may or may not be the channels at the + * edges of the sub band. The target channel may be "outside" of the + * span of the sampled channels. + * + * Driver may choose the pair (for 2 Tx chains) of measurements (see + * struct iwl4965_eeprom_calib_ch_info) for which the actual measured + * txpower comes closest to the desired txpower. Usually, though, + * the middle set of measurements is closest to the regulatory limits, + * and is therefore a good choice for all txpower calculations (this + * assumes that high accuracy is needed for maximizing legal txpower, + * while lower txpower configurations do not need as much accuracy). + * + * Driver should interpolate both members of the chosen measurement pair, + * i.e. for both Tx chains (radio transmitters), unless the driver knows + * that only one of the chains will be used (e.g. only one tx antenna + * connected, but this should be unusual). The rate scaling algorithm + * switches antennas to find best performance, so both Tx chains will + * be used (although only one at a time) even for non-MIMO transmissions. + * + * Driver should interpolate factory values for temperature, gain table + * index, and actual power. The power amplifier detector values are + * not used by the driver. + * + * Sanity check: If the target channel happens to be one of the sample + * channels, the results should agree with the sample channel's + * measurements! + * + * + * 5) Find difference between desired txpower and (interpolated) + * factory-measured txpower. Using (interpolated) factory gain table index + * (shown elsewhere) as a starting point, adjust this index lower to + * increase txpower, or higher to decrease txpower, until the target + * txpower is reached. Each step in the gain table is 1/2 dB. + * + * For example, if factory measured txpower is 16 dBm, and target txpower + * is 13 dBm, add 6 steps to the factory gain index to reduce txpower + * by 3 dB. + * + * + * 6) Find difference between current device temperature and (interpolated) + * factory-measured temperature for sub-band. Factory values are in + * degrees Celsius. To calculate current temperature, see comments for + * "4965 temperature calculation". + * + * If current temperature is higher than factory temperature, driver must + * increase gain (lower gain table index), and vice verse. + * + * Temperature affects gain differently for different channels: + * + * 2.4 GHz all channels: 3.5 degrees per half-dB step + * 5 GHz channels 34-43: 4.5 degrees per half-dB step + * 5 GHz channels >= 44: 4.0 degrees per half-dB step + * + * NOTE: Temperature can increase rapidly when transmitting, especially + * with heavy traffic at high txpowers. Driver should update + * temperature calculations often under these conditions to + * maintain strong txpower in the face of rising temperature. + * + * + * 7) Find difference between current power supply voltage indicator + * (from "initialize alive") and factory-measured power supply voltage + * indicator (EEPROM). + * + * If the current voltage is higher (indicator is lower) than factory + * voltage, gain should be reduced (gain table index increased) by: + * + * (eeprom - current) / 7 + * + * If the current voltage is lower (indicator is higher) than factory + * voltage, gain should be increased (gain table index decreased) by: + * + * 2 * (current - eeprom) / 7 + * + * If number of index steps in either direction turns out to be > 2, + * something is wrong ... just use 0. + * + * NOTE: Voltage compensation is independent of band/channel. + * + * NOTE: "Initialize" uCode measures current voltage, which is assumed + * to be constant after this initial measurement. Voltage + * compensation for txpower (number of steps in gain table) + * may be calculated once and used until the next uCode bootload. + * + * + * 8) If setting up txpowers for MIMO rates (rate indexes 8-15, 24-31), + * adjust txpower for each transmitter chain, so txpower is balanced + * between the two chains. There are 5 pairs of tx_atten[group][chain] + * values in "initialize alive", one pair for each of 5 channel ranges: + * + * Group 0: 5 GHz channel 34-43 + * Group 1: 5 GHz channel 44-70 + * Group 2: 5 GHz channel 71-124 + * Group 3: 5 GHz channel 125-200 + * Group 4: 2.4 GHz all channels + * + * Add the tx_atten[group][chain] value to the index for the target chain. + * The values are signed, but are in pairs of 0 and a non-negative number, + * so as to reduce gain (if necessary) of the "hotter" channel. This + * avoids any need to double-check for regulatory compliance after + * this step. + * + * + * 9) If setting up for a CCK rate, lower the gain by adding a CCK compensation + * value to the index: + * + * Hardware rev B: 9 steps (4.5 dB) + * Hardware rev C: 5 steps (2.5 dB) + * + * Hardware rev for 4965 can be determined by reading CSR_HW_REV_WA_REG, + * bits [3:2], 1 = B, 2 = C. + * + * NOTE: This compensation is in addition to any saturation backoff that + * might have been applied in an earlier step. + * + * + * 10) Select the gain table, based on band (2.4 vs 5 GHz). + * + * Limit the adjusted index to stay within the table! + * + * + * 11) Read gain table entries for DSP and radio gain, place into appropriate + * location(s) in command (struct iwl4965_txpowertable_cmd). + */ + +/** + * When MIMO is used (2 transmitters operating simultaneously), driver should + * limit each transmitter to deliver a max of 3 dB below the regulatory limit + * for the device.

Selecting the 3945 builds iwl3945.ko and iwl_legacy.ko, and selecting the 4965 builds iwl4965.ko and iwl_legacy.ko. iwl-legacy.ko contains code shared between both devices. The 3945 is an ABG/BG device, with no support for 802.11n. The 4965 is a 2x3 ABGN device.

Do not exceed (saturation - backoff[rate]); + * reduce target txpower if necessary. + * + * Backoff values below are in 1/2 dB units (equivalent to steps in + * txpower gain tables): + * + * OFDM 6 - 36 MBit: 10 steps (5 dB) + * OFDM 48 MBit: 15 steps (7.5 dB) + * OFDM 54 MBit: 17 steps (8.5 dB) + * OFDM 60 MBit: 20 steps (10 dB) + * CCK all rates: 10 steps (5 dB) + * + * Backoff values apply to saturation txpower on a per-transmitter basis; + * when using MIMO (2 transmitters), each transmitter uses the same + * saturation level provided in EEPROM, and the same backoff values; + * no reduction (such as with regulatory txpower limits) is required. + * + * Saturation and Backoff values apply equally to 20 Mhz (legacy) channel + * widths and 40 Mhz (.11n HT40) channel widths; there is no separate + * factory measurement for ht40 channels. + * + * The result of this step is the final target txpower. The rest of + * the steps figure out the proper settings for the device to achieve + * that target txpower. + * + * + * 3) Determine (EEPROM) calibration sub band for the target channel, by + * comparing against first and last channels in each sub band + * (see struct iwl4965_eeprom_calib_subband_info). + * + * + * 4) Linearly interpolate (EEPROM) factory calibration measurement sets, + * referencing the 2 factory-measured (sample) channels within the sub band. + * + * Interpolation is based on difference between target channel's frequency + * and the sample channels' frequencies. Since channel numbers are based + * on frequency (5 MHz between each channel number), this is equivalent + * to interpolating based on channel number differences. + * + * Note that the sample channels may or may not be the channels at the + * edges of the sub band. The target channel may be "outside" of the + * span of the sampled channels. + * + * Driver may choose the pair (for 2 Tx chains) of measurements (see + * struct iwl4965_eeprom_calib_ch_info) for which the actual measured + * txpower comes closest to the desired txpower. Usually, though, + * the middle set of measurements is closest to the regulatory limits, + * and is therefore a good choice for all txpower calculations (this + * assumes that high accuracy is needed for maximizing legal txpower, + * while lower txpower configurations do not need as much accuracy). + * + * Driver should interpolate both members of the chosen measurement pair, + * i.e. for both Tx chains (radio transmitters), unless the driver knows + * that only one of the chains will be used (e.g. only one tx antenna + * connected, but this should be unusual). The rate scaling algorithm + * switches antennas to find best performance, so both Tx chains will + * be used (although only one at a time) even for non-MIMO transmissions. + * + * Driver should interpolate factory values for temperature, gain table + * index, and actual power. The power amplifier detector values are + * not used by the driver. + * + * Sanity check: If the target channel happens to be one of the sample + * channels, the results should agree with the sample channel's + * measurements! + * + * + * 5) Find difference between desired txpower and (interpolated) + * factory-measured txpower. Using (interpolated) factory gain table index + * (shown elsewhere) as a starting point, adjust this index lower to + * increase txpower, or higher to decrease txpower, until the target + * txpower is reached. Each step in the gain table is 1/2 dB. + * + * For example, if factory measured txpower is 16 dBm, and target txpower + * is 13 dBm, add 6 steps to the factory gain index to reduce txpower + * by 3 dB. + * + * + * 6) Find difference between current device temperature and (interpolated) + * factory-measured temperature for sub-band. Factory values are in + * degrees Celsius. To calculate current temperature, see comments for + * "4965 temperature calculation". + * + * If current temperature is higher than factory temperature, driver must + * increase gain (lower gain table index), and vice verse. + * + * Temperature affects gain differently for different channels: + * + * 2.4 GHz all channels: 3.5 degrees per half-dB step + * 5 GHz channels 34-43: 4.5 degrees per half-dB step + * 5 GHz channels >= 44: 4.0 degrees per half-dB step + * + * NOTE: Temperature can increase rapidly when transmitting, especially + * with heavy traffic at high txpowers. Driver should update + * temperature calculations often under these conditions to + * maintain strong txpower in the face of rising temperature. + * + * + * 7) Find difference between current power supply voltage indicator + * (from "initialize alive") and factory-measured power supply voltage + * indicator (EEPROM). + * + * If the current voltage is higher (indicator is lower) than factory + * voltage, gain should be reduced (gain table index increased) by: + * + * (eeprom - current) / 7 + * + * If the current voltage is lower (indicator is higher) than factory + * voltage, gain should be increased (gain table index decreased) by: + * + * 2 * (current - eeprom) / 7 + * + * If number of index steps in either direction turns out to be > 2, + * something is wrong ... just use 0. + * + * NOTE: Voltage compensation is independent of band/channel. + * + * NOTE: "Initialize" uCode measures current voltage, which is assumed + * to be constant after this initial measurement. Voltage + * compensation for txpower (number of steps in gain table) + * may be calculated once and used until the next uCode bootload. + * + * + * 8) If setting up txpowers for MIMO rates (rate indexes 8-15, 24-31), + * adjust txpower for each transmitter chain, so txpower is balanced + * between the two chains. There are 5 pairs of tx_atten[group][chain] + * values in "initialize alive", one pair for each of 5 channel ranges: + * + * Group 0: 5 GHz channel 34-43 + * Group 1: 5 GHz channel 44-70 + * Group 2: 5 GHz channel 71-124 + * Group 3: 5 GHz channel 125-200 + * Group 4: 2.4 GHz all channels + * + * Add the tx_atten[group][chain] value to the index for the target chain. + * The values are signed, but are in pairs of 0 and a non-negative number, + * so as to reduce gain (if necessary) of the "hotter" channel. This + * avoids any need to double-check for regulatory compliance after + * this step. + * + * + * 9) If setting up for a CCK rate, lower the gain by adding a CCK compensation + * value to the index: + * + * Hardware rev B: 9 steps (4.5 dB) + * Hardware rev C: 5 steps (2.5 dB) + * + * Hardware rev for 4965 can be determined by reading CSR_HW_REV_WA_REG, + * bits [3:2], 1 = B, 2 = C. + * + * NOTE: This compensation is in addition to any saturation backoff that + * might have been applied in an earlier step. + * + * + * 10) Select the gain table, based on band (2.4 vs 5 GHz). + * + * Limit the adjusted index to stay within the table! + * + * + * 11) Read gain table entries for DSP and radio gain, place into appropriate + * location(s) in command (struct iwl4965_txpowertable_cmd). + */ + +/** + * When MIMO is used (2 transmitters operating simultaneously), driver should + * limit each transmitter to deliver a max of 3 dB below the regulatory limit + * for the device.

If no lower rate available, switch to + * legacy mode (no HT40 channel, no MIMO, no short guard interval). + * c) If using MIMO, set command's mimo_delimiter to number of entries + * using MIMO (3 or 6). + * d) After trying 2 HT rates, switch to legacy mode (no HT40 channel, + * no MIMO, no short guard interval), at the next lower bit rate + * (e.g. if second HT bit rate was 54, try 48 legacy), and follow + * legacy procedure for remaining table entries. + * + * 2) If using legacy initial rate: + * a) Use the initial rate for only one entry. + * b) For each following entry, reduce the rate to next lower available + * rate, until reaching the lowest available rate. + * c) When reducing rate, also switch antenna selection. + * d) Once lowest available rate is reached, repeat this rate until + * rate table is filled (16 entries), switching antenna each entry. + * + * + * ACCUMULATING HISTORY + * + * The rate scaling algorithm for 4965 devices, as implemented in Linux driver, + * uses two sets of frame Tx success history: One for the current/active + * modulation mode, and one for a speculative/search mode that is being + * attempted. If the speculative mode turns out to be more effective (i.e. + * actual transfer rate is better), then the driver continues to use the + * speculative mode as the new current active mode. + * + * Each history set contains, separately for each possible rate, data for a + * sliding window of the 62 most recent tx attempts at that rate. The data + * includes a shifting bitmap of success(1)/failure(0), and sums of successful + * and attempted frames, from which the driver can additionally calculate a + * success ratio (success / attempted) and number of failures + * (attempted - success), and control the size of the window (attempted). + * The driver uses the bit map to remove successes from the success sum, as + * the oldest tx attempts fall out of the window. + * + * When the 4965 device makes multiple tx attempts for a given frame, each + * attempt might be at a different rate, and have different modulation + * characteristics (e.g. antenna, fat channel, short guard interval), as set + * up in the rate scaling table in the Link Quality command. The driver must + * determine which rate table entry was used for each tx attempt, to determine + * which rate-specific history to update, and record only those attempts that + * match the modulation characteristics of the history set. + * + * When using block-ack (aggregation), all frames are transmitted at the same + * rate, since there is no per-attempt acknowledgment from the destination + * station. The Tx response struct iwl_tx_resp indicates the Tx rate in + * rate_n_flags field. After receiving a block-ack, the driver can update + * history for the entire block all at once. + * + * + * FINDING BEST STARTING RATE: + * + * When working with a selected initial modulation mode (see below), the + * driver attempts to find a best initial rate. The initial rate is the + * first entry in the Link Quality command's rate table. + * + * 1) Calculate actual throughput (success ratio * expected throughput, see + * table below) for current initial rate. Do this only if enough frames + * have been attempted to make the value meaningful: at least 6 failed + * tx attempts, or at least 8 successes. If not enough, don't try rate + * scaling yet. + * + * 2) Find available rates adjacent to current initial rate. Available means: + * a) supported by hardware && + * b) supported by association && + * c) within any constraints selected by user + * + * 3) Gather measured throughputs for adjacent rates. These might not have + * enough history to calculate a throughput. That's okay, we might try + * using one of them anyway! + * + * 4) Try decreasing rate if, for current rate: + * a) success ratio is < 15% || + * b) lower adjacent rate has better measured throughput || + * c) higher adjacent rate has worse throughput, and lower is unmeasured + * + * As a sanity check, if decrease was determined above, leave rate + * unchanged if: + * a) lower rate unavailable + * b) success ratio at current rate > 85% (very good) + * c) current measured throughput is better than expected throughput + * of lower rate (under perfect 100% tx conditions, see table below) + * + * 5) Try increasing rate if, for current rate: + * a) success ratio is < 15% || + * b) both adjacent rates' throughputs are unmeasured (try it!) || + * b) higher adjacent rate has better measured throughput || + * c) lower adjacent rate has worse throughput, and higher is unmeasured + * + * As a sanity check, if increase was determined above, leave rate + * unchanged if: + * a) success ratio at current rate < 70%. This is not particularly + * good performance; higher rate is sure to have poorer success. + * + * 6) Re-evaluate the rate after each tx frame. If working with block- + * acknowledge, history and statistics may be calculated for the entire + * block (including prior history that fits within the history windows), + * before re-evaluation. + * + * FINDING BEST STARTING MODULATION MODE: + * + * After working with a modulation mode for a "while" (and doing rate scaling), + * the driver searches for a new initial mode in an attempt to improve + * throughput. The "while" is measured by numbers of attempted frames: + * + * For legacy mode, search for new mode after: + * 480 successful frames, or 160 failed frames + * For high-throughput modes (SISO or MIMO), search for new mode after: + * 4500 successful frames, or 400 failed frames + * + * Mode switch possibilities are (3 for each mode): + * + * For legacy: + * Change antenna, try SISO (if HT association), try MIMO (if HT association) + * For SISO: + * Change antenna, try MIMO, try shortened guard interval (SGI) + * For MIMO: + * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI) + * + * When trying a new mode, use the same bit rate as the old/current mode when + * trying antenna switches and shortened guard interval. When switching to + * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate + * for which the expected throughput (under perfect conditions) is about the + * same or slightly better than the actual measured throughput delivered by + * the old/current mode. + * + * Actual throughput can be estimated by multiplying the expected throughput + * by the success ratio (successful / attempted tx frames). Frame size is + * not considered in this calculation; it assumes that frame size will average + * out to be fairly consistent over several samples. The following are + * metric values for expected throughput assuming 100% success ratio. + * Only G band has support for CCK rates: + * + * RATE: 1 2 5 11 6 9 12 18 24 36 48 54 60 + * + * G: 7 13 35 58 40 57 72 98 121 154 177 186 186 + * A: 0 0 0 0 40 57 72 98 121 154 177 186 186 + * SISO 20MHz: 0 0 0 0 42 42 76 102 124 159 183 193 202 + * SGI SISO 20MHz: 0 0 0 0 46 46 82 110 132 168 192 202 211 + * MIMO 20MHz: 0 0 0 0 74 74 123 155 179 214 236 244 251 + * SGI MIMO 20MHz: 0 0 0 0 81 81 131 164 188 222 243 251 257 + * SISO 40MHz: 0 0 0 0 77 77 127 160 184 220 242 250 257 + * SGI SISO 40MHz: 0 0 0 0 83 83 135 169 193 229 250 257 264 + * MIMO 40MHz: 0 0 0 0 123 123 182 214 235 264 279 285 289 + * SGI MIMO 40MHz: 0 0 0 0 131 131 191 222 242 270 284 289 293 + * + * After the new mode has been tried for a short while (minimum of 6 failed + * frames or 8 successful frames), compare success ratio and actual throughput + * estimate of the new mode with the old.

For any given beacon, the "silence reference" is + * the maximum of last 60 samples (20 beacons * 3 receivers). + * + * 2). 10-beacon history of strongest signal level, as indicated + * by (beacon_energy_[abc] & 0x0FF00) >> 8, across the 3 receivers, + * i.e. the strength of the signal through the best receiver at the + * moment. These measurements are "upside down", with lower values + * for stronger signals, so max energy will be *minimum* value. + * + * Then for any given beacon, the driver must determine the *weakest* + * of the strongest signals; this is the minimum level that needs to be + * successfully detected, when using the best receiver at the moment. + * "Max cck energy" is the maximum (higher value means lower energy!) + * of the last 10 minima.

Bootstrap looks + * at the BSM_DRAM_* registers, which now point to the runtime instruction + * image and the cached (modified) runtime data (*not* the initialization + * uCode). Bootstrap reloads these runtime images into SRAM, and restarts the + * uCode from where it left off before the power-down. + * + * NOTE: Initialization uCode does *not* run as part of the save/restore + * procedure. + * + * This save/restore method is mostly for autonomous power management during + * normal operation (result of POWER_TABLE_CMD). Platform suspend/resume and + * RFKILL should use complete restarts (with total re-initialization) of uCode, + * allowing total shutdown (including BSM memory). + * + * Note that, during normal operation, the host DRAM that held the initial + * startup data for the runtime code is now being used as a backup data cache + * for modified data! If you need to completely re-initialize the NIC, make + * sure that you use the runtime data image from the uCode distribution file, + * not the modified/saved runtime data.

The - module will be called iwl3945. diff --git a/drivers/net/wireless/iwlwifi/Makefile b/drivers/net/wireless/iwlwifi/Makefile index 25be742c69c9..aab7d15bd5ed 100644 --- a/drivers/net/wireless/iwlwifi/Makefile +++ b/drivers/net/wireless/iwlwifi/Makefile @@ -1,36 +1,23 @@ -obj-$(CONFIG_IWLWIFI) += iwlcore.o -iwlcore-objs := iwl-core.o iwl-eeprom.o iwl-hcmd.o iwl-power.o -iwlcore-objs += iwl-rx.o iwl-tx.o iwl-sta.o -iwlcore-objs += iwl-scan.o iwl-led.o -iwlcore-$(CONFIG_IWL3945) += iwl-legacy.o -iwlcore-$(CONFIG_IWL4965) += iwl-legacy.o -iwlcore-$(CONFIG_IWLWIFI_DEBUGFS) += iwl-debugfs.o -iwlcore-$(CONFIG_IWLWIFI_DEVICE_TRACING) += iwl-devtrace.o - -# If 3945 is selected only, iwl-legacy.o will be added -# to iwlcore-m above, but it needs to be built in. -iwlcore-objs += $(iwlcore-m) - -CFLAGS_iwl-devtrace.o := -I$(src) - # AGN obj-$(CONFIG_IWLAGN) += iwlagn.o iwlagn-objs := iwl-agn.o iwl-agn-rs.o iwl-agn-led.o iwlagn-objs += iwl-agn-ucode.o iwl-agn-tx.o iwlagn-objs += iwl-agn-lib.o iwl-agn-rx.o iwl-agn-calib.o iwlagn-objs += iwl-agn-tt.o iwl-agn-sta.o iwl-agn-eeprom.o -iwlagn-$(CONFIG_IWLWIFI_DEBUGFS) += iwl-agn-debugfs.o -iwlagn-$(CONFIG_IWL4965) += iwl-4965.o -iwlagn-$(CONFIG_IWL5000) += iwl-agn-rxon.o iwl-agn-hcmd.o iwl-agn-ict.o -iwlagn-$(CONFIG_IWL5000) += iwl-5000.o -iwlagn-$(CONFIG_IWL5000) += iwl-6000.o -iwlagn-$(CONFIG_IWL5000) += iwl-1000.o -iwlagn-$(CONFIG_IWL5000) += iwl-2000.o +iwlagn-objs += iwl-core.o iwl-eeprom.o iwl-hcmd.o iwl-power.o +iwlagn-objs += iwl-rx.o iwl-tx.o iwl-sta.o +iwlagn-objs += iwl-scan.o iwl-led.o +iwlagn-objs += iwl-agn-rxon.o iwl-agn-hcmd.o iwl-agn-ict.o +iwlagn-objs += iwl-5000.o +iwlagn-objs += iwl-6000.o +iwlagn-objs += iwl-1000.o +iwlagn-objs += iwl-2000.o + +iwlagn-$(CONFIG_IWLWIFI_DEBUGFS) += iwl-agn-debugfs.o +iwlagn-$(CONFIG_IWLWIFI_DEBUGFS) += iwl-debugfs.o +iwlagn-$(CONFIG_IWLWIFI_DEVICE_TRACING) += iwl-devtrace.o -# 3945 -obj-$(CONFIG_IWL3945) += iwl3945.o -iwl3945-objs := iwl3945-base.o iwl-3945.o iwl-3945-rs.o iwl-3945-led.o -iwl3945-$(CONFIG_IWLWIFI_DEBUGFS) += iwl-3945-debugfs.o +CFLAGS_iwl-devtrace.o := -I$(src) ccflags-y += -D__CHECK_ENDIAN__ diff --git a/drivers/net/wireless/iwlwifi/iwl-3945-debugfs.c b/drivers/net/wireless/iwlwifi/iwl-3945-debugfs.c deleted file mode 100644 index ef0835b01b6b..000000000000 --- a/drivers/net/wireless/iwlwifi/iwl-3945-debugfs.c +++ /dev/null @@ -1,522 +0,0 @@ -/****************************************************************************** - * - * GPL LICENSE SUMMARY - * - * Copyright(c) 2008 - 2010 Intel Corporation.

The rest of - * the steps figure out the proper settings for the device to achieve - * that target txpower. - * - * - * 3) Determine (EEPROM) calibration sub band for the target channel, by - * comparing against first and last channels in each sub band - * (see struct iwl4965_eeprom_calib_subband_info). - * - * - * 4) Linearly interpolate (EEPROM) factory calibration measurement sets, - * referencing the 2 factory-measured (sample) channels within the sub band. - * - * Interpolation is based on difference between target channel's frequency - * and the sample channels' frequencies. Since channel numbers are based - * on frequency (5 MHz between each channel number), this is equivalent - * to interpolating based on channel number differences. - * - * Note that the sample channels may or may not be the channels at the - * edges of the sub band. The target channel may be "outside" of the - * span of the sampled channels. - * - * Driver may choose the pair (for 2 Tx chains) of measurements (see - * struct iwl4965_eeprom_calib_ch_info) for which the actual measured - * txpower comes closest to the desired txpower. Usually, though, - * the middle set of measurements is closest to the regulatory limits, - * and is therefore a good choice for all txpower calculations (this - * assumes that high accuracy is needed for maximizing legal txpower, - * while lower txpower configurations do not need as much accuracy). - * - * Driver should interpolate both members of the chosen measurement pair, - * i.e. for both Tx chains (radio transmitters), unless the driver knows - * that only one of the chains will be used (e.g. only one tx antenna - * connected, but this should be unusual). The rate scaling algorithm - * switches antennas to find best performance, so both Tx chains will - * be used (although only one at a time) even for non-MIMO transmissions. - * - * Driver should interpolate factory values for temperature, gain table - * index, and actual power. The power amplifier detector values are - * not used by the driver. - * - * Sanity check: If the target channel happens to be one of the sample - * channels, the results should agree with the sample channel's - * measurements! - * - * - * 5) Find difference between desired txpower and (interpolated) - * factory-measured txpower. Using (interpolated) factory gain table index - * (shown elsewhere) as a starting point, adjust this index lower to - * increase txpower, or higher to decrease txpower, until the target - * txpower is reached. Each step in the gain table is 1/2 dB. - * - * For example, if factory measured txpower is 16 dBm, and target txpower - * is 13 dBm, add 6 steps to the factory gain index to reduce txpower - * by 3 dB. - * - * - * 6) Find difference between current device temperature and (interpolated) - * factory-measured temperature for sub-band. Factory values are in - * degrees Celsius. To calculate current temperature, see comments for - * "4965 temperature calculation". - * - * If current temperature is higher than factory temperature, driver must - * increase gain (lower gain table index), and vice verse. - * - * Temperature affects gain differently for different channels: - * - * 2.4 GHz all channels: 3.5 degrees per half-dB step - * 5 GHz channels 34-43: 4.5 degrees per half-dB step - * 5 GHz channels >= 44: 4.0 degrees per half-dB step - * - * NOTE: Temperature can increase rapidly when transmitting, especially - * with heavy traffic at high txpowers. Driver should update - * temperature calculations often under these conditions to - * maintain strong txpower in the face of rising temperature. - * - * - * 7) Find difference between current power supply voltage indicator - * (from "initialize alive") and factory-measured power supply voltage - * indicator (EEPROM). - * - * If the current voltage is higher (indicator is lower) than factory - * voltage, gain should be reduced (gain table index increased) by: - * - * (eeprom - current) / 7 - * - * If the current voltage is lower (indicator is higher) than factory - * voltage, gain should be increased (gain table index decreased) by: - * - * 2 * (current - eeprom) / 7 - * - * If number of index steps in either direction turns out to be > 2, - * something is wrong ... just use 0. - * - * NOTE: Voltage compensation is independent of band/channel. - * - * NOTE: "Initialize" uCode measures current voltage, which is assumed - * to be constant after this initial measurement. Voltage - * compensation for txpower (number of steps in gain table) - * may be calculated once and used until the next uCode bootload. - * - * - * 8) If setting up txpowers for MIMO rates (rate indexes 8-15, 24-31), - * adjust txpower for each transmitter chain, so txpower is balanced - * between the two chains. There are 5 pairs of tx_atten[group][chain] - * values in "initialize alive", one pair for each of 5 channel ranges: - * - * Group 0: 5 GHz channel 34-43 - * Group 1: 5 GHz channel 44-70 - * Group 2: 5 GHz channel 71-124 - * Group 3: 5 GHz channel 125-200 - * Group 4: 2.4 GHz all channels - * - * Add the tx_atten[group][chain] value to the index for the target chain. - * The values are signed, but are in pairs of 0 and a non-negative number, - * so as to reduce gain (if necessary) of the "hotter" channel. This - * avoids any need to double-check for regulatory compliance after - * this step. - * - * - * 9) If setting up for a CCK rate, lower the gain by adding a CCK compensation - * value to the index: - * - * Hardware rev B: 9 steps (4.5 dB) - * Hardware rev C: 5 steps (2.5 dB) - * - * Hardware rev for 4965 can be determined by reading CSR_HW_REV_WA_REG, - * bits [3:2], 1 = B, 2 = C. - * - * NOTE: This compensation is in addition to any saturation backoff that - * might have been applied in an earlier step. - * - * - * 10) Select the gain table, based on band (2.4 vs 5 GHz). - * - * Limit the adjusted index to stay within the table! - * - * - * 11) Read gain table entries for DSP and radio gain, place into appropriate - * location(s) in command (struct iwl4965_txpowertable_cmd). - */ - -/** - * When MIMO is used (2 transmitters operating simultaneously), driver should - * limit each transmitter to deliver a max of 3 dB below the regulatory limit - * for the device.

It only enable promiscous mode instead of multicast hash table mode, so the hash table function will not be activated and all multicast frames will be recieved in this condition. This patch fixes the following issues with the r6040 NIC operating in multicast: 1) When the IFF_ALLMULTI flag is set, we should write 0xffff to the NIC hash table registers to make it process multicast traffic. 2) When the number of multicast address to handle is smaller than MCAST_MAX, we should use the NIC multicast registers MID1_{L,M,H}. 3) The hashing of the address was not correct, due to an invalid substraction (15 - (crc & 0x0f)) instead of (crc & 0x0f) and an incorrect crc algorithm (ether_crc_le) instead of (ether_crc). 4) If necessary, we should set HASH_EN flag in MCR0 to enable multicast hash table function.

In addition, updated igb_ndo_get_vf_config function to show the actual rate limit to the user. The rate limitation can be configured only when the link is up. The rate limit value can be ranged between 0 and actual link speed measured in Mbps. A value of '0' disables the rate limit for this specific VF. iproute2 usage will be 'ip link set ethX vf Y rate Z'. After the command is made, the rate will be changed instantly. To view the current rate limit, use 'ip link show ethX'. The rates will be zeroed only upon driver reload or a link speed change. This feature is being supported only by 82576 device.

All drivers will drop frames if they fail to TX the frame, and they must also properly manage the queues (if they didn't, mac80211 would already warn). Removing the ability for drivers to return a BUSY value also allows significant cleanups of the TX TX handling code in mac80211. Note that this also fixes a bug in ath9k_htc, the old "return -1" there was wrong.

When the driver is alerted to a change in the DCB negotiated parameters, it calls dcb_setapp to update the dcbnl application tlvs list making it available to user mode applications and registered notifiers.

Siena does not allow the levels to be configured (or, if it does, this is done by the MC firmware and is not configurable by drivers). So far as I can tell, the module parameters are not used by our internal scripts and have not been documented (with the exception of the short parameter descriptions). Therefore, remove them and always initialise Falcon with the default values.

Even if it is enabled in the running kernel, it can still be temporarily disabled, for instance during suspend. Runtime PM is opportunistic in nature, and should not be relied on for toggling power. In case the interface is removed and re-added while runtime PM is disabled, the FW will fail to boot, as it is mandatory to toggle power between boots. For instance, this can happen during suspend in case one of the devices fails to suspend before the MMC host suspends, but after mac80211 was suspended. The interface will be removed and reactivated without toggling the power. Fix this by calling mmc_power_save_host/mmc_power_restore_host in wl1271_sdio_power_on/off functions. It will toggle the power to the chip even if runtime PM is disabled. The runtime PM functions should still be called to make sure runtime PM does not opportunistically power the chip off (e.g. after resuming from system suspend).

In case it runs out of memory reserved for RX frames, it'll have no other choice but to drop packets received from the AP. Thus, it is important to handle RX data interrupts as soon as possible, before handling anything else. In addition, since there are enough TX descriptors to go around, it is better to first send TX frames, and only then handle TX completions. Fix this by changing the order of function calls in wl1271_irq_work.

In addition to the few CPU cycles it takes to claim and release the bus, it may also cause undesired side effects such as the MMC host stopping its internal clocks. Since only the wl12xx_sdio driver drives this SDIO card, it is safe to claim the SDIO host once (on power on), and release it only when turning the power off.

Currently the interrupt handler wakes up a worker for handling interrupts in process context. A cleaner and more efficient design would be to request a threaded interrupt handler. This handler's priority is very high, and can do blocking operations such as SDIO/SPI transactions. Some work can be deferred, mostly calls to mac80211 APIs (ieee80211_rx_ni and ieee80211_tx_status). By deferring such work to a different worker, we can keep the irq handler thread more I/O responsive. In addition, on multi-core systems the two threads can be scheduled on different cores, which will improve overall performance. The use of WL1271_FLAG_IRQ_PENDING & WL1271_FLAG_IRQ_RUNNING was changed. For simplicity, always query the FW for more pending interrupts. Since there are relatively long bursts of interrupts, the extra FW status read overhead is negligible. In addition, this enables registering the IRQ handler with the ONESHOT option.

However, since resetting the interrupt requires bus transactions, this cannot be done from an interrupt context. Thus, requesting a level interrupt would require to disable the irq and re-enable it after the HW is acknowledged. Since we now request a threaded irq, this can also be done by specifying the IRQF_ONESHOT flag. Triggering on an edge can be problematic in some platforms, if the sampling frequency is not sufficient for detecting very frequent interrupts. In case an interrupt is missed, the driver will hang as the interrupt line will stay high until it is acknowledged by the driver, which will never happen. Fix this by requesting a level triggered interrupt, with the IRQF_ONESHOT flag.

In addition it fails to setup max_rates in the ieee80211_hw struct, This behavior may be responsible for the problems noted in Bug 14168.

Hence, introduce a new method rt2x00queue_get_tx_queue that is only valid for tx queues and use it in places where only tx queues are valid. Furthermore, this new method is quite short and as such can be inlined to avoid the function call overhead. This only converts the txdone functions of drivers that don't use an ATIM queue and the generic tx path. Signed-off-by: Helmut Schaa Signed-off-by: Ivo van Doorn Signed-off-by: John W.

The ATIM queue is considered to be a TX queue by the drivers that support the queue. Therefore include support for the ATIM queue to the rt2x00queue_get_tx_queue function so that the drivers that support the ATIM queue can also use that function. Add the support in such a way that drivers that do not support the ATIM queue are not penalized in their efficiency.

This can be problem for plcp health and ack health checking. I.e. with 2 plcp errors happens randomly in 2 ms duration, we exceed plcp delta threshold equal to 100 (2*100/2). Also checking ack's in short time, can results not necessary false positive and firmware reset, for example when channel is noised and we do not receive ACKs frames or when remote device does not send ACKs at the moment. Patch change code to do statistic check and possible recovery only if 99ms elapsed from last check. Forced delay should assure we have good statistic data to estimate hardware state.

This seems to happen because by the time wl1251_ps_elp_wakeup is called elp_work might still be pending. After wakeup is done, the processing may take some time, during which 5ms might expire and elp_work might get scheduled. In this case, ss soon as 1st thread finishes work and releases the mutex, elp_work will then put the device to sleep without 5ms delay. In addition 1st thread will queue additional elp_work needlessly. Fix this by cancelling work in wl1251_ps_elp_wakeup instead.

The devices supported by ixgbe can be configured to run in IEEE or CEE modes but not both. With the DCBX set capabilities bit we add an explicit signal that must be used to toggle between these modes. This patch adds logic to fail the CEE command set_hw_all() which programs the device with a CEE configuration if the CEE caps bit is not set. Similarly, IEEE set commands will fail if the IEEE caps bit is not set. We allow most CEE config set commands to occur because they do not touch the hardware until set_hw_all() is called. The one exception to the above is the {set|get}app routines. These must always be protected by caps bits to ensure side effects do not corrupt the current configured mode. By requiring the caps bit to be set correctly we can maintain a consistent configuration in the hardware for CEE or IEEE modes and prevent partial hardware configurations that may occur if user space does not send a complete IEEE or CEE configurations. It is expected that user space will signal a DCBX mode before programming device.

In order to get this working as expected the tc_to_tx net device mapping is configured as well as the prio_tc_map. skb priorities are mapped across a range of queue pairs to get a distribution per traffic class. The maximum number of queue pairs used while in DCB mode is capped at 64. The hardware max is actually 128 queues but 64 is sufficient for now and allocating more seemed a bit excessive. It is easy enough to increase the cap later if need be. To get the 802.1Q priority tags inserted correctly ixgbe was previously using the skb queue_mapping field to directly set the 802.1Q priority. This no longer works because we have removed the 1:1 mapping between queues and traffic class. Each ring is aligned with an 802.1Qaz traffic class so here we add an extra field to the ring struct to identify the 802.1Q traffic class. This uses an extra byte of the ixgbe_ring struct fortunately there was a 2byte hole, struct ixgbe_ring { void * desc; /* 0 8 */ struct device * dev; /* 8 8 */ struct net_device * netdev; /* 16 8 */ union { struct ixgbe_tx_buffer * tx_buffer_info; /* 8 */ struct ixgbe_rx_buffer * rx_buffer_info; /* 8 */ }; /* 24 8 */ long unsigned int state; /* 32 8 */ u8 atr_sample_rate; /* 40 1 */ u8 atr_count; /* 41 1 */ u16 count; /* 42 2 */ u16 rx_buf_len; /* 44 2 */ u16 next_to_use; /* 46 2 */ u16 next_to_clean; /* 48 2 */ u8 queue_index; /* 50 1 */ u8 reg_idx; /* 51 1 */ u16 work_limit; /* 52 2 */ /* XXX 2 bytes hole, try to pack */ u8 * tail; /* 56 8 */ /* --- cacheline 1 boundary (64 bytes) --- */ Now we can set the VLAN priority directly and it will be correct. User space can indicate the 802.1Qaz priority using the SO_PRIORITY setsocket() option and QOS layer will steer the skb to the correct rings. Additionally using the multiq qdisc with a queue_mapping action works as well.

Previously ixgbe only supported a 1:1 mapping. Now we can enable and disable hardware DCB support when multiple traffic classes are actually being used. This allows the default case all priorities mapped to traffic class 0 to work in normal hardware mode and utilize the full packet buffer. This patch does not address putting the hardware in 4TC mode so packet buffer space may be underutilized in this case. A follow up patch can address this optimization. But at least we have the hooks to do this now. Also CEE will behave as it always has and map priorities 1:1 with traffic classes.

Under heavy load a timeout may actually occur without being the result of an error and when this occurs it is not practical to perform a full VF driver reset on every message timeout. Instead, just return an error (which is already done) and the VF driver will have an opportunity to retry the operation.

In addition, updated ixgbe_ndo_get_vf_config function to show the actual rate limit to the user. The rate limitation can be configured only when the link is up and the link speed is 10Gb. The rate limit value can be 0 or ranged between 11 and actual link speed measured in Mbps. A value of '0' disables the rate limit for this specific VF. iproute2 usage will be 'ip link set ethX vf Y rate Z'. After the command is made, the rate will be changed instantly. To view the current rate limit, use 'ip link show ethX'. The rates will be zeroed only upon driver reload or a link speed change. This feature is being supported by 82599 and X540 devices.

On AR9380, calling that function too often can result in an increase of stuck beacons due to differences in the handling of the queue enable/disable functionality. With this patch, the queue will only be explicitly stopped if the previous data frames were not sent successfully. With the beacon code being the only remaining user of ath9k_hw_stoptxdma, this function can be simplified in order to remove the now pointless attempts at waiting for transmission completion, which would never happen at this point due to the different method of tx scheduling of the beacon queue.

That leads to have any macvlan port in bridge mode to not work because the packets are dropped due to a bad checksum. If the macvlan is in bridge mode, the packet is forwarded to another macvlan port and reach the network stack where it looks for a checksum but this one was not computed due to the offloading of the lower device. In this case, we have to set the packet with CHECKSUM_UNNECESSARY when it is forwarded to a bridged port and restore the previous value of ip_summed when the packet goes to the lowerdev.

The PV protocol is also implemented by frontend drivers in other OSes too, such as the BSDs and even Windows. The patch is based on the driver from the xen.git pvops kernel tree but has been put through the checkpatch.pl wringer plus several manual cleanup passes and review iterations. The driver has been moved from drivers/xen/netback to drivers/net/xen-netback. One major change from xen.git is that the guest transmit path (i.e. what looks like receive to netback) has been significantly reworked to remove the dependency on the out of tree PageForeign page flag (a core kernel patch which enables a per page destructor callback on the final put_page). This page flag was used in order to implement a grant map based transmit path (where guest pages are mapped directly into SKB frags). Instead this version of netback uses grant copy operations into regular memory belonging to the backend domain. Reinstating the grant map functionality is something which I would like to revisit in the future. Note that this driver depends on 2e820f58f7ad "xen/irq: implement bind_interdomain_evtchn_to_irqhandler for backend drivers" which is in linux next via the "xen-two" tree and is intended for the 2.6.39 merge window: git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/backends this branch has only that single commit since 2.6.38-rc2 and is safe for cross merging into the net branch.
