* b43: Remove deprecated 'qual' from returned RX statusLarry Finger2009-11-061-2/+0

* b43: do not stack-allocate pio rx/tx header and tail buffersAlbert Herranz2009-10-071-76/+92
| | | | | | | | | | | 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.

* b43: Add optional verbose runtime statisticsMichael Buesch2009-09-231-0/+4
| | | | | | | | | | 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.

* b43: Rewrite suspend/resume codeMichael Buesch2009-09-231-16/+3
| | | | | | | | | 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>

* b43: Use a threaded IRQ handlerMichael Buesch2009-09-081-15/+8
| | | | | | | | | | | | 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.

* b43: Dynamically control log verbosityMichael Buesch2009-01-291-4/+1
| | | | | | | | | | | | | | | | | | | | Dynamically control the log verbosity with a module parameter. This enables us to dynamically enable debugging messages (or disable info, warn, error messages) via module parameter or /sys/module/b43/parameters/verbose. This increases the module size by about 3k. But in practice it reduces the module size for the user, because some distributions ship the b43 module with CONFIG_B43_DEBUG set, which increases the module by about 15k. So with this patch applied, distributions should really _disable_ CONFIG_B43_DEBUG. There is no reason to keep it in a production-release kernel. So we have a net reduction in size by about 12k. This patch also adds a printk of the wireless core revision, so people don't have to enable SSB debugging to get the wireless core revision.

* b43: Automatically probe for opensource firmwareMichael Buesch2009-01-291-1/+31
| | | | | | | | | | | | | | | | | First probe for proprietary firmware and then probe for opensource firmware. This way around it's a win-win situation. 1) If proprietary fw is available, it will work. 2) If opensource firmware is available, but no proprietary (Distros can only ship open fw) it might work. 3) If both open and proprietary are available, it will work, because it selects the proprietary. We currently don't prefer the open fw in this case, because it doesn't work on all devices. It would introduce a regression otherwise. The remaining FIXMEs in this patch are harmless, because they only matter on multiband devices, which are not implemented yet anyway.

* b43: Rewrite TX power adjustmentMichael Buesch2008-08-291-0/+10
| | | | | | | | | | | | | | | This patch rewrites the TX power recalculation algorithms to scale better with changed enviromnent. If there's low TX traffic, the power will be checked against the desired values every 60 seconds. If there is high TX traffic, the check is redone every 2 seconds. This improves the reaction times a lot and confuses the rate control less. It will also reduce the time it initially takes to tune to a new TX power value. With the old algorithm it could take about 30 to 45 seconds to settle to a new power value. This will happen in about two to four seconds now.

* b43: Add PIO support for PCMCIA devicesMichael Buesch2008-04-081-3/+56
| | | | | | | | | | | | | | | | | | | | This adds PIO support back (D'oh!) for PCMCIA devices. This is a complete rewrite of the old PIO code. It does actually work and we get reasonable performance out of it on a modern machine. On a PowerBook G4 I get a few MBit for TX and a few more for RX. So it doesn't work as well as DMA (of course), but it's a _lot_ faster than the old PIO code (only got a few kBit with that). The limiting factor is the host CPU speed. So it will generate 100% CPU usage when the network interface is heavily loaded. A voluntary preemption point in the RX path makes sure Desktop Latency isn't hurt. PIO is needed for 16bit PCMCIA devices, as we really don't want to poke with the braindead DMA mechanisms on PCMCIA sockets. Additionally, not all PCMCIA sockets do actually support DMA in 16bit mode (mine doesn't). Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* cfg80211 API for channels/bitrates, mac80211 and driver conversionJohannes Berg2008-02-291-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch creates new cfg80211 wiphy API for channel and bitrate registration and converts mac80211 and drivers to the new API. The old mac80211 API is completely ripped out. All drivers (except ath5k) are updated to the new API, in many cases I expect that optimisations can be done. Along with the regulatory code I've also ripped out the IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be unnecessary if the hardware simply gives us whatever channels it wants to support and we then enable/disable them as required, which is pretty much required for travelling. Additionally, the patch adds proper "basic" rate handling for STA mode interface, AP mode interface will have to have new API added to allow userspace to set the basic rate set, currently it'll be empty... However, the basic rate handling will need to be moved to the BSS conf stuff. I do expect there to be bugs in this, especially wrt. transmit power handling where I'm basically clueless about how it should work.

* b43: Add driver load messagesMichael Buesch2008-02-151-0/+6
| | | | | | | | | | | | | | | | | | This adds printk messages with basic information about the driver being loaded. This information includes a summary of the compiled-in features, which simplifies bug-reporting and debugging a lot. Also a firmware ID is printed. This is a unique identifier blob for a specific version of the firmware. This ID is attached to a specific version of the firmware blob in b43-fwcutter (see fwcutter git). This helps users to select the right firmware for their device. This also makes it possible to use automated scripts to fetch and extract the right firmware for the driver. (the script will grep the .ko for the "Firmware-ID: xxx" string. While the driver might still support other versions of the firmware for backward compatibility, this will always print out the officially supported version, which people _should_ use.
