| H A D | if_ath.c | diff 227346 Tue Nov 08 16:21:07 MST 2011 adrian Merge in some fixes from the if_ath_tx branch. * Close down some of the kickpcu races, where the interrupt handler can and will run concurrently with the taskqueue. * Close down the TXQ active/completed race between the interrupt handler and the concurrently running tx completion taskqueue function. * Add some tx and rx interrupt count tracking, for debugging. * Fix the kickpcu logic in ath_rx_proc() to not simply drain and restart the TX queue - instead, assume the hardware isn't (too) confused and just restart RX DMA. This may break on previous chipsets, so if it does I'll add a HAL flag and conditionally handle this (ie, for broken chipsets, I'll just restore the "stop PCU / flush things / restart PCU" logic.) * Misc stuff Sponsored by: Hobnob, Inc. |
