| * b43: Fix possible NULL pointer dereference in DMA codeMichael Buesch2008-06-131-33/+32Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a possible NULL pointer dereference in an error path of the DMA allocation error checking code. This is also necessary for a future DMA API change that is on its way into the mainline kernel that adds an additional dev parameter to dma_mapping_error(). This patch moves the whole struct b43_dmaring struct initialization right before any DMA allocation operation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

|/ | | | | | | | | | | | | | | | | | After 2.6.24 there was a plan to make the PM core acquire all device semaphores during a suspend/hibernation to protect itself from concurrent operations involving device objects. That proved to be too heavy-handed and we found a better way to achieve the goal, but before it happened, we had introduced the functions device_pm_schedule_removal() and destroy_suspended_device() to allow drivers to "safely" destroy a suspended device and we had adapted some drivers to use them. Now that these functions are no longer necessary, it seems reasonable to remove them and modify their users to use the normal device unregistration instead. Signed-off-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a fastpath for the common workloads to the MAC suspend flushing. In common workloads the FIFO flush will take between 100 and 200 microseconds. So we want to avoid calling msleep() in the common case, as it will waste over 800 microseconds + scheduler overhead. This fastpath will hit in workloads where only small chunks of data are transmitted (downloading a file) or when a TX rate bigger or equal to 24MBit/s is used when transmitting lots of stuff (iperf). So in the commonly used workloads it will basically always hit. In case the fastpath is not hit, there's no real performance or latency disadvantage from that. And yes, I measured this. So this is not one of these bad Programmer Likeliness Assumptions that are always wrong. ;) Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | This fixes the initialization of the PHY TX control words in shared memory. These control words are used for management frames like beacons. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* | b43: Fix beacon BH updateMichael Buesch2008-04-082-42/+54
| | | | | | | | | | | | | | | | This fixes beacon updating in the bottomhalf. In case the device is busy, we will defer to later in the IRQ handler. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* | b43: Beaconing fixesMichael Buesch2008-04-082-6/+37
| | | | | | | | | | | | | | | | These are some beaconing related fixes. Basically it prevents the card from triggering the beacon IRQ over and over again. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* | b43: Fix TBTT and PU timingsMichael Buesch2008-04-082-8/+39
| | | | | | | | | | | | | | This fixes some timings for pre-TBTT and synthetic PU. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* | b43: Add more N-PHY stuffMichael Buesch2008-04-084-12/+41
| | | | | | | | | | | | | | | | | | This adds some minor stuff for N-PHY support. Nothing special. Adds Analog switching and some TODOs for RSSI processing. Just a patch I had floating around for quite some time now. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* | b43: Use SSB block-I/O to do PIOMichael Buesch2008-04-082-83/+91
| | | | | | | | | | | | | | | | | | | | | | 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.

* | ssb: Turn suspend/resume upside downMichael Buesch2008-04-081-4/+6
| | | | | | | | | | | | | | | | | | Turn the SSB bus suspend mechanism upside down. Instead of deciding by an internal reference count when to suspend/resume, let the parent bus call us in their suspend/resume routine.
