The FW might free TX descriptors without freeing the corresponding memory blocks, especially when dynamic memory is enabled. In cases where memory blocks are not freed at all, the driver will keep waiting for more memory blocks indefinitely.

The net layer takes a look and incorrectly assumes the queue has been down for several seconds, and generates a tx_timeout. One way to fix this is to bump the trans_start counter while scanning so that the network layer knows that the device is still alive, but I think the tx_timeout handler is implemented wrongly here and not of any real use, so I vote to remove it. As explained at http://marc.info/?l=linux-wireless&m=130430311115755&w=2 the watchdog is primarily meant to deal with lockup on the hardware TX path (detected by the tx queue being stopped for an extended period of time), but this is unlikely to happen with libertas. In this case, the tx queue is stopped only while waiting for lbs_thread to send the queued frame to the driver, and lbs_thread wakes up the queue immediately after, even if the frame could not be sent correctly. So, the only hardware-related possibility that this catches is if hw_host_to_card hangs - this is something I have never seen. And if it were to happen, nothing done by lbs_tx_timeout would actually wake up lbs_thread any quicker than otherwise. Removing this oddly-behaving spuriously-firing tx_timeout handler should fix an occasional kernel crash during resume (http://dev.laptop.org/ticket/10748) Signed-off-by: Daniel Drake Acked-by: Dan Williams Signed-off-by: John W.

Unnccesarily doing nfcal in all supported chains leads to invalid nf readings on extn chains and these invalid values got updated into history buffer. While loading those values from history buffer is moving the chip to deaf state. This issue was observed in AR9002/AR9003 chips while doing associate/dissociate in HT40 mode and interface up/down in iterative manner. After some iterations, the chip was moved to deaf state. Somehow the pci devices are recovered by poll work after chip reset. Raading the nf values in all supported extension chains when the hw is not yet configured in HT40 mode results invalid values.

Kao" Date: Fri, 6 May 2011 10:40:15 -0700 Subject: iwlwifi: support the svtool messages interactions through nl80211 test mode This patch adds the feature to support the test mode operation through the generic netlink channel NL80211_CMD_TESTMODE between intel wireless device iwlwifi and the user space application svtool. The main purpose is to create a transportation layer between the iwlwifi device and the user space application so that the interaction between the user space application svtool and the iwlwifi device in the kernel space is in a way of generic netlink messaging. The detail specific functions are: 1. The function iwl_testmode_cmd() is added to digest the svtool test command from the user space application. The svtool test commands are categorized to three types : commands to be processed by the device ucode, commands to access the registers, and commands to be processed at the driver level(such as reload the ucode). iwl_testmode_cmd() dispatches the commands the corresponding handlers and reply to user space regarding the command execution status. Extra data is returned to the user space application if there's any. 2. The function iwl_testmode_ucode_rx_pkt() is added to multicast all the spontaneous messages from the iwlwifi device to the user space. Regardless the message types, whenever there is a valid spontaneous message received by the iwlwifi ISR, iwl_testmode_ucode_rx_pkt() is invoked to multicast the message content to user space. The message content is not attacked and the message parsing is left to the user space application. Implementation guidelines: 1. The generic netlink messaging for iwliwif test mode is through NL80211_CMD_TESTMODE channel, therefore, the codes need to follow the regulations set by cfg80211.ko to get the actual device instance ieee80211_ops via cfg80211.ko, so that the iwlwifi device is indicated with ieee80211_ops and can be actually accessed. Therefore, a callback iwl_testmode_cmd() is added to the structure iwlagn_hw_ops in iwl-agn.c. 2. It intends to utilize those low level device access APIs from iwlwifi device driver (ie. iwlagn.ko) rather than creating it's own set of device access functions. For example, iwl_send_cmd(), iwl_read32(), iwl_write8(), and iwl_write32() are reused. 3. The main functions are maintained in new files instead of spreading all over the existing iwlwifi driver files. The new files added are : drivers/net/wireless/iwlwifi/iwl-sv-open.c - to handle the user space test mode application command and reply the respective command status to the user space application. - to multicast the spontaneous messages from device to user space. drivers/net/wireless/iwlwifi/iwl-testmode.h - the commonly referenced definitions for the TLVs used in the generic netlink messages Signed-off-by: Cindy H.

This leads to a problem with scanning since the passive dwell time isn't restricted appropriately and a scan that includes passive channels will never finish if only the PAN context is associated since the default dwell time of 120ms won't fit into the normal 100 TU DTIM interval. Fix the function by using for_each_context() and also reorganise the other functions a bit to take advantage of each other making the code easier to read.

From a programming point of view, this new bus type differs from AMBA and does not use AMBA common registers. It also differs enough from SSB. We decided that a new bus driver is needed to keep the code clean. In its current form, the driver detects devices present on the bus and registers them in the system. It allows registering BCMA drivers for specified bus devices and provides them basic operations. The bus driver itself includes two important bus managing drivers: ChipCommon core driver and PCI(c) core driver. They are early used to allow correct initialization. Currently code is limited to supporting buses on PCI(e) devices, however the driver is designed to be used also on other hosts. The host abstraction layer is implemented and already used for PCI(e). Support for PCI(e) hosts is working and seems to be stable (access to 80211 core was tested successfully on a few devices). We can still optimize it by using some fixed windows, but this can be done later without affecting any external code. Windows are just ranges in MMIO used for accessing cores on the bus.

charset=UTF-8 Content-Transfer-Encoding: 8bit Some of the BCM43xx chips contain cores that are attached to the SSB, but are inactive as they do not connect to the external environment. These must not be registered. Several of these types are handled in driver ssb; however, the specific case of an inactive 802.11 cores is now treated in b43 and b43legacy. Although the current setup works, this minor change will place all such workarounds in ssb, and simplify the code in drivers b43 and b43legacy.
