Subject: [RFC PATCH 00/11] md: support for asynchronous execution of RAID6 operations
Date: Thu, 13 Nov 2008 18:15:53 +0300 [thread overview]
Message-ID: <1226589364-5619-1-git-send-email-yanok@emcraft.com> (raw)
The following patch-set includes enhancements to the async_tx api and
modifications to md-raid6 to issue memory copies and parity calculations
asynchronously. Thus we may process copy operations and RAID-6 calculations
on the dedicated DMA engines accessible with ASYNC_TX API, and, as a result
off-load CPU, and improve the performance.
To reduce the code duplication in the raid driver this patch-set modifies
some raid-5 functions to make them possible to use in the raid-6 case.
The patch-set can be broken down into thee following main categories:
1) Additions to ASYNC_TX API (patches 1-3)
2) RAID-6 implementation (patches 4-10)
3) ppc440spe ADMA driver (patch 11) (it still has a number of problems,
provided only as a reference here)
