2009-06-10b43/legacy: port to cfg80211 rfkillJohannes Berg
This ports the b43/legacy rfkill code to the new API offered by cfg80211 and thus removes a lot of useless stuff.

2009-06-03rfkill: rewriteJohannes Berg
This patch completely rewrites the rfkill core to address the following deficiencies: * all rfkill drivers need to implement polling where necessary rather than having one central implementation * updating the rfkill state cannot be done from arbitrary contexts, forcing drivers to use schedule_work and requiring lots of code * rfkill drivers need to keep track of soft/hard blocked internally -- the core should do this * the rfkill API has many unexpected quirks, for example being asymmetric wrt. alloc/free and register/unregister * rfkill can call back into a driver from within a function the driver called -- this is prone to deadlocks and generally should be avoided * rfkill-input pointlessly is a separate module * drivers need to #ifdef rfkill functions (unless they want to depend on or select RFKILL) -- rfkill should provide inlines that do nothing if it isn't compiled in * the rfkill structure is not opaque -- drivers need to initialise it correctly (lots of sanity checking code required) -- instead force drivers to pass the right variables to rfkill_alloc() * the documentation is hard to read because it always assumes the reader is completely clueless and contains way TOO MANY CAPS * the rfkill code needlessly uses a lot of locks and atomic operations in locked sections * fix LED trigger to actually change the LED when the radio state changes -- this wasn't done before Tested-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> [thinkpad] Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

Auto-depend on HW_RANDOM, rather than "select"ing it. This way the user has the choice to enable or disable HWRNG support. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-01-29b43: Dynamically control log verbosityMichael Buesch
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.

2008-04-08b43: Use SSB block-I/O to do PIOMichael Buesch
This changes the b43-PIO code to use the new SSB block-I/O. This reduces the overhead by removing lots of function calls, pointer dereferencing, if-conditionals any byteswapping for each packet data word. This also fixes a harmless sparse endianness warning.

2008-04-08b43: Add PIO support for PCMCIA devicesMichael Buesch
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>
2008-02-28Use a separate config option for the b43 pci to ssb bridge.Alexey Zaytsev
The bridge code was unnecessary enabled by the b44 driver, but it prevents the bcm43xx driver from being loaded, as the bridge claims the same pci ids. Now we enable the birdge only if the b43{legacy} drivers are selected.

2008-01-28b43: Add NPHY kconfig optionMichael Buesch
This adds a new Kconfig option for enabling probing of N-PHYs. This option will be removed again once the stuff works. For now it is to help in development. This way real users won't execute the broken N-PHY codepaths, but the developers can easily enable N-PHY stuff. To enable N-PHY probing simply remove the BROKEN dependency and enable the option in the kernel config. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W.

2008-01-28b43: Remove PIO supportMichael Buesch
Remove b43 PIO support. DMA works well on all supported devices. There's no reason to use PIO. Additionally, new devices don't support PIO in hardware anymore. b43 PIO support is dead and unused code. After applying this patch please do git rm drivers/net/wireless/b43/pio.h git rm drivers/net/wireless/b43/pio.c to remove the main PIO support code.
