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.

2009-01-29b43: Accessing the TSF via mac80211Alina Friedrichsen
This allows the mac80211 high level code to access the TSF. This is e.g. needed for BSSID merges in the IBSS mode. The second version adds locking and removes the now unnecessary debugfs entries. Thanks to Michael Buesch! :) Signed-off-by: Alina Friedrichsen <x-alina@gmx.net> Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-12-19b43: Add key memory dumpingMichael Buesch
This adds an option to dump all crypto related memory to the kernel log. Obviously, it should not be enabled on productive systems. ;) Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-06-27b43: Add debugfs firmware debugging knobMichael Buesch
This adds a firmware debugging knob to debugfs. With this knob it's possible to enable advanced runtime firmware checks. For now it only implements one sanity check for the mac-suspend. In future there'll probably be more. If CONFIG_B43_DEBUG is disabled, these checks will collapse to nothing. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W.

2008-06-26b43: Remove "shm" and "ucode_regs" debugfs filesMichael Buesch
We don't need these two dump-files anymore, as we can easily do this in userspace now. Use b43-fwdump from the b43-tools repository to dump microcode registers. Use "b43-fwdump -s" to dump SHM (or use -S to do a binary dump) Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-06-26b43: Add debugfs files for random SHM accessMichael Buesch
This adds debugfs files for random SHM access. This is needed in order to implement firmware and driver debugging scripts in userspace. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-06-26b43: Add debugfs files for MMIO register accessMichael Buesch
This adds debugfs files for reading and writing arbitrary wireless core registers. This is useful for debugging. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-05-07b43: Rewrite LO calibration algorithmMichael Buesch
This patch distributes the Local Oscillator calibration bursts over time, so that calibration only happens when it's actually needed. Currently we periodically perform a recalibration of the whole table. The table is huge and this takes lots of time. Additionally only small bits of the table are actually needed at a given time. So instead of maintaining a huge table with all possible calibration values, we create dynamic calibration settings that a) We only calibrate when they are actually needed. b) Are cached for some time until they expire. So a recalibration might happen if we need a calibration setting that's not cached, or if the active calibration setting expires. Currently the expire timeout is set to 30 seconds. We may raise that in future. This patch reduces overall memory consumption by nuking the huge static calibration tables. This patch has been tested on several 4306, 4311 and 4318 flavours.
