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) _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
