2013-01-17b43: Fix firmware loading when driver is built into the kernelLarry Finger1-13/+41
commit 5e20a4b53094651d80f856ff55a916b999dbb57a upstream. Recent versions of udev cause synchronous firmware loading from the probe routine to fail because the request to user space would time out. The original fix for b43 (commit 6b6fa58) moved the firmware load from the probe routine to a work queue, but it still used synchronous firmware loading. This method is OK when b43 is built as a module; however, it fails when the driver is compiled into the kernel. This version changes the code to load the initial firmware file using request_firmware_nowait(). A completion event is used to hold the work queue until that file is available. This driver reads several firmware files - the remainder can be read synchronously. On some test systems, the async read fails; however, a following synch read works, thus the async failure falls through to the sync try.

2012-11-05b43: Fix oops on unload when firmware not foundLarry Finger1-0/+2
commit f89ff6441df06abc2d95f3ef67525923032d6283 upstream. When b43 fails to find firmware when loaded, a subsequent unload will oops due to calling ieee80211_unregister_hw() when the corresponding register call was never made. Commit 2d838bb608e2d1f6cb4280e76748cb812dc822e7 fixed the same problem for b43legacy.

2012-04-27b43: only reload config after successful initializationSeth Forshee1-2/+8
Commit 2a19032 (b43: reload phy and bss settings after core restarts) introduced an unconditional call to b43_op_config() at the end of b43_op_start(). When firmware fails to load this can wedge the system. There's no need to reload the configuration after a failed initialization anyway, so only make the call if initialization was successful.

2012-03-13b43: Load firmware from a work queue and not from the probe routineLarry Finger1-27/+32
Recent changes in udev are causing problems for drivers that load firmware from the probe routine. As b43 has such a structure, it must be changed. As this driver loads more than 1 firmware file, changing to the asynchronous routine request_firmware_nowait() would be complicated. In this implementation, the probe routine starts a queue that calls the firmware loading routines. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.

2012-03-06b43: prevent firmware on bcm5354 from taking over wrong GPIO pinsHauke Mehrtens1-0/+2
When using the bcm5354 (Soc with integrated LP-PHY Wifi) with a recent firmware >= 478.104 it runs out of memory after a very short time in OpenWrt after doing an active scan or any thing else where packages are send. This was cased by a gpio misconfiguration, the firmware triggered the GPIO pins used for buttons on some devices and that caused an other driver (OpenWrt diag) listening for these buttons irqs to send many messages to the user space. This patch fixes the bug for my devices (Asus WL-520GU) and makes it work with firmware 666.2. Now the firmware just uses LED GPIO pin number 1 and not the button pins any more. This is the GPIO Pin layout used on my device, see [0]. GPIO pin layout: pin# name type 0 power led 1 wlan led 2 reset button 3 ses buttom This is the nvram configuration output of "nvram show |grep gpio" related nvram configuration: wl0gpio2=11 wl0gpio3=11 wl0gpio0=11 wl0gpio1=0x02 reset_gpio=2 [0]: https://dev.openwrt.org/browser/trunk/package/broadcom-diag/src/diag.c Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W.

2011-12-19b43: avoid packet losses in the dma worker code.francesco.gringoli@ing.unibs.it1-15/+40
Following Rafal request, we verified that on "modern" CPUs using one or more workers is equivalent. Here is patch V3 that addresses the packet loss bug in the dma engine using only one worker. ------- This patch addresses a bug in the dma worker code that keeps draining packets even when the hardware queues are full. In such cases packets can not be passed down to the device and are erroneusly dropped by the code. This problem was already discussed here http://www.mail-archive.com/b43-dev@lists.infradead.org/msg01413.html and acknowledged by Michael. Number of hardware queues is now defined in b43.h (B43_QOS_QUEUE_NUM).
