[Xen-devel] [PATCH 2/3] ioemu: add libpci fixup to handle recent change in PCIUtils

[Alexia Benington <alexbenington@xxxxxxxxx>]

Hi Yu,

What were the changes in libutils that triggered this patch?

I've been trying to get a domu guest to correctly use a passed through
VGA card, and noticed that some IO mappings are not as what the driver
in the guest expects to see. For example, one of the I/O range starts
from C000h. After the fixup, it was changed to C200h. I'm suspecting
this causes the guest driver not to work correctly, although there may
be other reasons. What do you think?

Thanks. :)

The following commit of PCIUtils changes what 'base_addr' contains.
Add a fixup to make sure the pass-through works when building against
different versions of PCIUtils.

   Fix base address flags when using sysfs method

   The base address flags are ignored when using sysfs method, while
   the proc and generic methods combined the flags into 'base_addr'.
   This inconsistency may fail some applications using libpci.
