[Xen-devel] [PATCH] [Xen 3.3] Containing MSI errors in msi emulation cod
Hi, Keir,
We found one problem related to MSI in Xen 3.3. If msi=0 is specified and guest
want to enable msi, qemu finds it can not enable it and quits. This problem is
not appicable for xen unstable since the "msi=x" switch is removed.
My patch let these cases be handled inside msi emulation code. If qemu can not
enable msi, guest will not receive MSI. But Qemu can still go on. But if guest
driver does not test MSI's functionality, guest device will stop to function.
Could you please apply the patch?
Best Regards
Haitao Shan
