Thread-topic: [Xen-devel] [PATCH 6/6] Add MSI support to XEN
Hi, Jan,
I do not want to touch drivers/pci/msi.c. Sorry, this part of code is
left in the patch duo to my mistake. The attached is the updated patch.
The reason that I add a new file is that I did not find a clean way to
use the original msi.c. There is code there managing vectors, which is
definitly not needed in dom0. Also I do not want to insert too many
"ifdef"s in that file.
Do I understand your comments correctly?

Best Regards
Haitao Shan
