Subject: [PATCH v2 0/4] Asynchronous raid6 acceleration (part 2 of 3)
Date: Mon, 31 Aug 2009 08:40:37 -0700 [thread overview]
Message-ID: <20090831153946.1068.86702.stgit@dwillia2-linux.ch.intel.com> (raw)
RAID6 acceleration support for the iop13xx ADMA engines. The iop13xx platform
has three Application DMA engines providing support for offloading raid
operations. Channel0 and Channel1 support memcpy and xor. Channel2 adds pq
support.
The combined series is available at:
git://git.kernel.org/pub/scm/linux/kernel/git/djbw/async_tx.git raid6
The changes since v1 are:
1/ Fix the case for continuing a p-disabled pq calculation
2/ A lockdep annotation for teaching lockdep about iop-adma cross channel
dependency submissions.
