Subject: [PATCH 0/19] Chaining sg lists for big IO commands v6
Date: Wed, 16 May 2007 10:32:14 +0200 [thread overview]
Message-ID: <11793043533744-git-send-email-jens.axboe@oracle.com> (raw)
(please ignore last posting, git send-email got hold of the
wrong directory...)
Hi,
Round 6 of the sg chaining patch set. Changes since v5:
- Support for more architectures. It should now run and work on
i386, x86-64, sparc, sparc64, ia64, and ppc (32 and 64-bit).
I have only tested i386/x86-64/ppc64 myself.
- Large command support is now automatically enabled by the
SCSI mid layer, if the arch supports sg chaining. The debug
queue entry in /sys/block/<dev>/queue/max_segments still exists
if you want to tweak it further. The default limit is now
2048 entries, or at least 8mb ios. Remember that you still need
to tweak the soft limit to allow the block layer to build large
commands, that is the max_sectors_kb variable in the same directory.
- Add kerneldoc documentation to scatterlist.h
It's solid here, so please give it a spin. I'd like to get some
performance results as well, if someone feels inclined to do so.
