* USB: Disable hub-initiated LPM for comms devices.Sarah Sharp2012-05-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hub-initiated LPM is not good for USB communications devices. Comms devices should be able to tell when their link can go into a lower power state, because they know when an incoming transmission is finished. Ideally, these devices would slam their links into a lower power state, using the device-initiated LPM, after finishing the last packet of their data transfer. If we enable the idle timeouts for the parent hubs to enable hub-initiated LPM, we will get a lot of useless LPM packets on the bus as the devices reject LPM transitions when they're in the middle of receiving data. Worse, some devices might blindly accept the hub-initiated LPM and power down their radios while they're in the middle of receiving a transmission. The Intel Windows folks are disabling hub-initiated LPM for all USB communications devices under a xHCI USB 3.0 host. In order to keep the Linux behavior as close as possible to Windows, we need to do the same in Linux. Set the disable_hub_initiated_lpm flag for for all USB communications drivers. I know there aren't currently any USB 3.0 devices that implement these class specifications, but we should be ready if they do.

* rtlwifi: Add missing DMA buffer unmapping for PCI driversLarry Finger2012-04-111-1/+6
| | | | | | | | | | | | | | In https://bugzilla.kernel.org/show_bug.cgi?id=42976, a system with driver rtl8192se used as an AP suffers from "Out of SW-IOMMU space" errors. These are caused by the DMA buffers used for beacons never being unmapped.

* rtlwifi: Preallocate USB read buffers and eliminate kalloc in read routineLarry Finger2012-04-112-19/+21
| | | | | | | | | | | | | | | | | The current version of rtlwifi for USB operations uses kmalloc to acquire a 32-bit buffer for each read of the device. When _usb_read_sync() is called with the rcu_lock held, the result is a "sleeping function called from invalid context" BUG. This is reported for two cases in https://bugzilla.kernel.org/show_bug.cgi?id=42775. The first case has the lock originating from within rtlwifi and could be fixed by rearranging the locking; however, the second originates from within mac80211. The kmalloc() call is removed from _usb_read_sync() by creating a ring buffer pointer in the private area and allocating the buffer data in the probe routine.

| | | | | | | | | | | | | | | In https://bugzilla.redhat.com/show_bug.cgi?id=770207, slowdowns of driver rtl8192ce are reported. One fix (commit a9b89e2) has already been applied, and it helped, but the maximum RX speed would still drop to 1 Mbps. As in the previous fix, the initial gain was determined to be the problem; however, the problem arises from a setting of the gain when scans are started. Driver rtl8192de also has the same code structure - this one is fixed as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Driver rtl8192ce when used with the RTL8188CE device would start at about 20 Mbps on a 54 Mbps connection, but quickly drop to 1 Mbps. One of the symptoms is that the AP would need to retransmit each packet 4 of 5 times before the driver would acknowledge it. Recovery is possible only by unloading and reloading the driver. This problem was reported at https://bugzilla.redhat.com/show_bug.cgi?id=770207. The problem is due to a missing update of the gain setting.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When driver rtl8192cu is used with the debug level set to 3 or greater, the result is "sleeping function called from invalid context" due to an rcu_read_lock() call in the DM refresh routine in driver rtl8192c. This lock is not necessary as the USB driver does not use the struct being protected, thus the lock is set only when a PCI interface is active.

The kernel bugzilla report is https://bugzilla.kernel.org/show_bug.cgi?id=42632, which reports a udev timeout on boot. The first mail thread, which was on LKML (http://lkml.indiana.edu/hypermail/ linux/kernel/1112.3/00965.html) was for a WARNING that occurs after a suspend/resume cycle for rtl8192cu. The scond mail thread (http://marc.info/?l=linux-wireless&m=132655490826766&w=2) concerned changes in udev that break drivers that delay while firmware is loaded on modprobe. This patch converts all rtlwifi-based drivers to use the asynchronous firmware loading mechanism. Drivers rtl8192ce, rtl8192cu and rtl8192de share a common callback routine. Driver rtl8192se needs different handling of the firmware, thus it has its own code. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Cc: Stable <stable@vger.kernel.org> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In https://bugzilla.redhat.com/show_bug.cgi?id=771656, a kernel bug was triggered due to a failed skb allocation that was not checked. This event lead to an audit of all memory allocations in the complete rtlwifi family of drivers. This patch fixes the rest.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It does seem odd though to have a DBG_EMERG and not always emit it. What might also be useful for any embedded use is to add CONFIG_RTLWIFI_DEBUG to conditionally remove all of the debug logging code to reduce the largish object size. This reduces the object size by about 1/3 (250KB) when CONFIG_RTLWIFI_DEBUG is not set. $ size drivers/net/wireless/rtlwifi/built-in.o* text data bss dec hex filename 368722 55333 94224 518279 7e887 drivers/net/wireless/rtlwifi/built-in.o.new 586904 55333 127216 769453 bbdad drivers/net/wireless/rtlwifi/built-in.o.old Signed-off-by: Joe Perches <joe@perches.com> Acked-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.
