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.

2008-06-27b43: Add simple firmware watchdogMichael Buesch

2008-06-27ssb, b43, b43legacy, b44: Rewrite SSB DMA APIMichael Buesch
This is a rewrite of the DMA API for SSB devices. This is needed, because the old (non-existing) "API" made too many bad assumptions on the API of the host-bus (PCI). This introduces an almost complete SSB-DMA-API that maps to the lowlevel bus-API based on the bustype. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W.

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.

2008-05-21mac80211: move TX info into skb->cbJohannes Berg
This patch converts mac80211 and all drivers to have transmit information and status in skb->cb rather than allocating extra memory for it and copying all the data around. To make it fit, a union is used where only data that is necessary for all steps is kept outside of the union. A number of fixes were done by Ivo, as well as the rt2x00 part of this patch.

This patch modifies struct ieee80211_tx_control to give band info and the rate index (instead of rate pointers) to drivers.

2008-05-14mac80211: use hardware flags for signal/noise unitsBruno Randolf
trying to clean up the signal/noise code. the previous code in mac80211 had confusing names for the related variables, did not have much definition of what units of signal and noise were provided and used implicit mechanisms from the wireless extensions. this patch introduces hardware capability flags to let the hardware specify clearly if it can provide signal and noise level values and which units it can provide. this also anticipates possible new units like RCPI in the future. for signal: IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific IEEE80211_HW_SIGNAL_DB - dB difference to unspecified reference point IEEE80211_HW_SIGNAL_DBM - dBm, difference to 1mW for noise we currently only have dBm: IEEE80211_HW_NOISE_DBM - dBm, difference to 1mW if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has to provide the maximum value (max_signal) it reports in order for applications to make sense of the signal values. i tried my best to find out for each driver what it can provide and update it but i'm not sure (?) for some of them and used the more conservative guess in doubt. this can be fixed easily after this patch has been merged by changing the hardware flags of the driver.

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.

This is in particular true for rt2x00 who needs to know the key algorithm and whether it is a shared or pairwise key. By passing the ieee80211_key_conf pointer it assures us that drivers can make full use of all information that it should know about a particular key. Additionally this patch updates all drivers to grab the hw_key_idx from the ieee80211_key_conf structure. v2: Removed bogus u16 cast v3: Add warning about ieee80211_tx_control pointers v4: Update warning about ieee80211_tx_control pointers Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

Some mainboards/CPUs don't allow DMA masks bigger than a certain limit. Some VIA crap^h^h^h^hdevices have an upper limit of 0xFFFFFFFF. So in this case a 64-bit b43 device would always fail to acquire the mask. Implement a workaround to fallback to lower DMA mask, as we can always also support a lower mask.
