12 years agoath6kl: Use mutex to protect dma buffer in sync read write
Raja Mani [Mon, 21 Nov 2011 06:56:51 +0000 (12:26 +0530)]
ath6kl: Use mutex to protect dma buffer in sync read write

Firmware crashes while starting Soft AP in 32 bit x86 platform.
The reason is that the single dma buffer (ar_sdio->dma_buffer)
is used in ath6kl_sdio_read_write_sync() for unaligned buffer
handling and this function is called in the multiple context
at the same time. So, finally hits dma buffer corruption and
firmware crash.

Mutex is used to protect dma buffer to avoid data corruption.
Spin lock can not used to fix this issue since mmc stack
read/write calls may for sleep.

Observed this issue with recently commited patch

called for each tx'ed frame and thus it makes sense to reduce its
runtime.

Do this by calculating the group index by this formula based on the SGI

idx = (HT40 * 2 * MINSTREL_MAX_STREAMS) +
      (SGI * MINSTREL_MAX_STREAMS) +
      (streams - 1)

Hence, the groups are ordered by th HT40 flag first, then by the SGI
flag and afterwards by the number of used streams.

program parameters from any virtual interface into
all contexts, but not only do we want to get rid of

might even be programmed for HT.

Explicitly program default QoS parameters into the
PAN context for P2P (the defaults are 11g but with
QoS disabled) to make device behaviour predictable.
