Per Bill Davidsen's request I have made available a 2.6.22.1 based
kernel with the current raid5 performance changes I have been working
on:
1/ Offload engine acceleration (recently merged for the 2.6.23
development cycle)
2/ Stripe-queue, an evolutionary change to the raid5 queuing model (take4)
The offload engine work only helps platforms with offload engines and
should not affect performance otherwise. The stripe-queue work is an
attempt to increase sequential write performance and should benefit
most platforms.
The patch series is available on the Xscale(r) IOP SourceForge page:
http://downloads.sourceforge.net/xscaleiop/patches-2.6.22.1-iop1-x86fix.tar.gz
Use quilt to apply the series on top of a fresh 2.6.22.1 source tree:
$ wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.22.1.tar.bz2
$ tar xjf linux-2.6.22.1.tar.bz2
$ cd linux-2.6.22.1
$ tar xzvf patches-2.6.22.1-iop1.tar.gz
$ cp patches/series.x86 patches/series
$ quilt push -a
Configure and build the kernel as normal, there are no configuration
options for stripe-queue.
Any feedback, bug report, fix, or suggestion is welcome.
Following these instructions . With 2.6.22.1 gets me the below(*) .
Undoubtedly I have missed some message that said us a differnat pathset
or something along those lines .
