Here is some more PCU locking enhancements I tested today while trying to resolve the WARN() that happens when we try to stop RX DMA and fail. While working on that I figured I'd work on the TX DMA stuff too, here's a shot at it. I can no longer get TX / RX DMA rants, please test and let me know if you do. I only tried some basic testing like rmmoding while scannign, which typicallly produced some errors. Now I don't get squat. Ben if you can test wit your super proprietary application that'd be great. This also simplifies locking considerably. This doesn't break suspend so I'm happy. It also depends on the last RX DMA fixes I had posted earlier. If you'd like to get an all-in-one patch of all my patches pending you can wget this file and git am it: http://www.kernel.org/pub/linux/kernel/people/mcgrof/patches/tmp/pending-mcgrof-2010-10-26-v1.patch sha1sum: 874a3cc1a57f7e26ad191cd7b5045315f94c5823 If they do indeed fix the rants, then great, but not sure if they warrant to be stable fixes. If this works trick was to not mess with contend on the PCU for RX or TX and for resets, all together. There is one call not protected here though, the ath_tx_start_dma() but not sure how to address that or if we need to. Luis R.
