2009-10-07b43: do not stack-allocate pio rx/tx header and tail buffersAlbert Herranz
The DMA-API debugging facility complains about b43 mapping memory from stack for SDIO-based cards. Indeed, b43 currently allocates the PIO RX/TX header and tail buffers from stack. The solution here is to use heap-allocated buffers instead. Signed-off-by: Albert Herranz <albert_herranz@yahoo.es> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-10-07b43: Fix PPC crash in rfkill polling on unloadLarry Finger
In Bugzilla No. 14181, a PowerMac G4 crashes on ifdown or module unload because the rfkill polling has not been stopped. For the x86 architectures, the attempt to reach a now unmapped register is not fatal as it is on PPC.

2009-09-29b43: Always use block-I/O for the PIO data registersMichael Buesch
On SDIO the PIO data register seems to be hardwired to LE. So the MACCTL bit has no effect on the endianness. So also use block-I/O for the last word of the packet. block-I/O is always LE.

2009-09-23b43: Don't abuse wl->current_dev in the led workMichael Buesch
Don't abuse wl->current_dev in the LED work for checking whether we're going down. Add an explicit variable. This fixes a crash on rmmod dereferencing the wl->current_dev NULL pointer in various other places of the driver. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W.

2009-09-23b43: Add LP PHY Analog Switch SupportThomas Ilnseher
The current verison of b43 uses "b43_phyop_switch_analog_generic" for A, G and LP phys. According to the spec, this is the wrong behaviour for the LP PHY (see: http://bcm-v4.sipsolutions.net/802.11/PHY/Anacore ) While no problems on the x86 plattform where seen, this leads to a crash on the BCM5354 SoC (MIPS 32 LE plattform). This patch implements the analog switch for LP PHYs according to the specs. It fixes the crash signed-off-by: Thomas Ilnseher <illth@gmx.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-09-23b43: Disable PMQ mechanismMichael Buesch
This reduces IRQ pressure by about one third on a saturated link by disabling the PMQ mechanism. We currently don't use that mechanism. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-09-23b43: Add optional verbose runtime statisticsMichael Buesch
This adds support for verbose runtime statistics. It defaults to off and must be enabled in debugfs, if desired. The first measurement may be incorrect, because statistics are not cleared after they got enabled through debugfs. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-09-23b43: Fix IRQ sync for SDIOMichael Buesch

2009-09-23b43: Add Soft-MAC SDIO device supportAlbert Herranz
This adds support for Soft-MAC SDIO devices to b43. The driver still lacks some fixes for SDIO devices, so it's currently marked as BROKEN. Signed-off-by: Albert Herranz <albert_herranz@yahoo.es> Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-09-23b43: Rewrite suspend/resume codeMichael Buesch
This removes most of the b43 suspend/resume code (it's handled by mac80211) and moves the registration of devices to the attachment phase. This is required, because we must not register/unregister devices on suspend/resume. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-09-23b43: Fix resume failureMichael Buesch
This fixes a resume failure where a signal is pending on resume so the firmware upload fails. This removes the interruptible sleep, because we don't really need it. In the worst case (with broken firmware) the sleep loop will take 1 second. In the common case (working firmware), it will only take a few milliseconds. So we don't really need to be interruptible.

2009-09-23b43: Force-wake queues on initMichael Buesch

2009-09-09b43: Really disable QoS, if requestedMichael Buesch
Currently, when QoS-disable is requested, we would leave QoS enabled in firmware, but only queue frames on one queue. Change that and also tell firmware about disabled QoS, so it completely ignores all the QoS parameters. Also don't upload the parameters, if QoS is disabled.

2009-09-08b43: Remove TX spinlockMichael Buesch
This removes the TX spinlock and defers TX to a workqueue to allow locking wl->mutex instead and to allow sleeping for register accesses. Signed-off-by: Michael Buesch <mb@bu3sch.de> Tested-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-09-08b43: Use a threaded IRQ handlerMichael Buesch
Use a threaded IRQ handler to allow locking the mutex and sleeping while executing an interrupt. This removes usage of the irq_lock spinlock, but introduces a new hardirq_lock, which is _only_ used for the PCI/SSB lowlevel hard-irq handler. Sleeping busses (SDIO) will use mutex instead.

2009-08-28b43: Implement antenna diversity support for LP-PHYGábor Stefanik

2009-08-28b43: Enable LP-PHY support by default and remove Kconfig warningGábor Stefanik
The most common LP-PHY device, BCM4312, is now fully functional. So, no need to say "probably won't work for you" anymore. It's also not "for debuggers and developers only", as it is perfectly usable for end-users now (at least for BCM4312). Signed-off-by: Gábor Stefanik <netrolller.3d@gmail.com> Signed-off-by: John W.

2009-08-28b43: Fix and update LP-PHY codeGábor Stefanik
-Fix a few nasty typos (b43_phy_* operations instead of b43_radio_*) in the channel tune routines. -Fix some typos & spec errors found by MMIO tracing. -Optimize b43_phy_write & b43_phy_mask/set/maskset to use only the minimal number of MMIO accesses. (Write is possible using a single 32-bit MMIO write, while set/mask/maskset can be done in 3 16-bit MMIOs). -Set the default channel back to 1, as the bug forcing us to use channel 7 is now fixed. With this, the device comes up, scans, associates, transmits, receives, monitors and injects on all channels - in other words, it's fully functional. Sensitivity and TX power are still sub-optimal, due to the lack of calibration (that's next on my list). Signed-off-by: Gábor Stefanik <netrolller.3d@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-08-28b43: LP-PHY: Fix and simplify Qdiv roundupGábor Stefanik
The Qdiv roundup routine is essentially a fixed-point division algorithm, using only integer math.

2009-08-28b43: LP-PHY: Fix a few typos in the RC calibration codeGábor Stefanik
