[Xen-devel] [PATCH 0/2] make upper field of 64 bit bar writable.

[Yuji Shimada <shimada-yxb@xxxxxxxxxxxxxxx>]

This series of patches makes upper field of 64 bit base address
register writable for pass-through device.

1. update ioemu-remote&ioemu to make upper field of 64 bit base
   address register writable.

2. update hvmloader to skip upper field of 64 bit base address
   register.


Current hvmloader does not handle 64 bit base address register, while
some devices have 64 bit base address register. To prevent hvmloader
to set some value to upper field of 64 bit base address register,
the field is hardwired to 0 by ioemu&ioemu-remote currently.

Upper field of 64 bit base address register should be writable to
follow pci spec. So the series of patches update both
ioemu-remote&ioemu and hvmloader.

Thanks,
