[PATCH v2 0/4] I/OAT: watchdog/reset,tcp_dma_copybreak and I/OAT ver.3 support
From: Maciej Sosnowski
Date: Fri Jul 18 2008 - 11:37:19 EST
This is version 2 of ioatdma patchset
which has been updated after first review comments.
The first three patches are a result of
ioatdma sustaining and performance tuning efforts
for both I/OAT versions 1.2 and 2.0.
The fourth patch is a new patch in this set.
It adds I/OAT version 3 support to ioatdma driver.
The main differences between v1 and v2 of this patchset are:
* "Increase sleep time in ioat_dma_self_test" change
has been separated from
"Add watchdog/reset functionality to ioatdma driver" patch
* tcp_dma_copybreak default value setting has been moved
from dmaengine to ioatdma driver
* "I/OAT version 3.0 support" patch has been added
* checkpatch problems have been resolved
This patches apply to kernel 2.6.26-rc9.
