Subject: [patch] block highmem zero bounce v15
Date: Mon, 24 Sep 2001 01:28:01 +0200 [thread overview]
Message-ID: <20010924012801.H2154@suse.de> (raw)
Hi,
I've uploaded a new version of the patch that allows direct I/O to
highmem memory without resorting to bouncing to lower memory. Changes
since last time include:
- Update to 2.4.10
- Fix SCSI dont-merge error. No corruption, just a performance
hit (me)
- Add single_sg_ok entry to SCSI hosts. An alternative solution would be
to always bounce single entry sg for highmem pages, however I don't
want decent drivers to take a hit on account of crap drivers. Now the
entire I/O path should be unaffected for non-highmem enabled
hosts/drivers. (me)
ATM only aic7xxx and sym53c8xxx have single_sg_ok enabled, others will
follow on a per-audit basis.
