From: Ryan Harper <ryanh@us.ibm.com> To: qemu-devel@nongnu.org Cc: Ryan Harper <ryanh@us.ibm.com>, kvm@vger.kernel.org Subject: [PATCH 0/2] LSI53C895A and scsi-disk fixes Date: Fri, 23 Jan 2009 08:21:17 -0600 [thread overview] Message-ID: <1232720479-21398-1-git-send-email-ryanh@us.ibm.com> (raw) While trying to get SLES10 SP2 installed to a scsi disk, I encountered a couple of errors. The first patch just adds support for ISTAT1 register to be read. The second patch handles re-entrance issues present in the lsi driver and scsi-disk. Due to the async/callback structure of the LSI and scsi code, there are situations where lsi_do_command() and scsi_send_command() can nest. Patch2 detects and handle these cases. Applying these two patches allows SLES10 SP2 to function properly. I've tested the scsi changes against Ubuntu 8.04.2, 8.10, RHEL5u2, openSuSE11, FreeBSD 7, Windows XP, Windows XP 64, 2k3 and didn't see any regressions. Signed-off-by: Ryan Harper <ryanh@us.ibm.com>
