Subject: [patch] PCI: disable MSI on more ATI NorthBridges
Date: Thu, 18 Oct 2007 17:14:36 +0800 [thread overview]
Message-ID: <5CAB7B5D6F8AB84AA868A46B47A507055D8C1D@sshaexmb1.amd.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 371 bytes --]
More ATI North Bridges like RS780 can't do MSI like its predecessors
in linux. Disable MSIs on them.
Signed-off-by: Shane Huang <shane.huang@amd.com>
Since there is some word wrapping problem with my mail client MS outlook
if I copy the patch into the text, so I'll have to attach the patch as
an attachment. Please check it.
Thanks
Best Regards
Shane
