From: Dan Williams <dan.j.williams <at> intel.com>
Subject: [PATCH 00/13] Asynchronous raid6 acceleration (part 1 of 2)
Newsgroups: gmane.linux.raid
Date: Wednesday 18th March 2009 19:20:16 UTC (over 8 years ago)
This series constitutes the pieces of the raid6 acceleration work that are
aimed at the next merge window.  It implements:
1/ An api for asynchronous raid6 parity generation and recovery routines
2/ Extensions to the dmaengine framework and dmatest
3/ RAID6 support for iop13xx
4/ Removal of the BUILD_BUG_ON in async_xor to support platforms with
   sizeof(dma_addr_t) > sizeof(void *).  This increases the stack
   utilization in the asynchronous path.

This series is available via git at:

	git://git.kernel.org/pub/scm/linux/kernel/git/djbw/async_tx.git
raid6

...it is based on git://neil.brown.name/md md-scratch

Part 2, which needs more testing, is the conversion of md/raid6.  It is
available at:

Dan Williams (12):
      dmatest: add pq support
      dmatest: add dma interrupts and callbacks
      dmatest: add xor test
      dmaengine: allow dma support for async_tx to be toggled
      iop-adma: P+Q self test
      iop-adma: P+Q support for iop13xx adma engines
      async_tx: add support for asynchronous RAID6 recovery operations
      async_tx: add support for asynchronous GF multiplication
      async_tx: add sum check flags
      async_tx: kill needless module_{init|exit}
      async_tx: provide __async_inline for HAS_DMA=n archs
      md/raid6: move raid6 data processing to raid6_pq.ko

Yuri Tikhonov (1):
      async_tx: don't use src_list argument of async_xor() for dma
addresses
