Subject: [PATCH v2] Enhancements to hvmloader for Xen 4.8
Date: Wed, 28 Sep 2016 19:48:47 -0400 [thread overview]
Message-ID: <1475106529-17443-1-git-send-email-konrad.wilk@oracle.com> (raw)
Hey!
These two patches came about as I was doing PCI passthrough with
rather large BAR regions and finding a lot of ballooning - which
was unnecessary as we only have 1744MB of MMIO space under 4GB and
all of the ballooning in and out would not help squeeze in a 2GB BAR
or higher in there.
Please review at your convience.

hvmloader: Use MB(x) and GB(x) macros
hvmloader, pci: Don't try to relocate memory if 64-bit BAR is bigger than ~2GB
