[PATCH 3/3] Move EPT identity mapping pages to allow a larger BIOS image

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Move from:
  0xfffbc000-0xfffbcfff
to:
  0xfeffc000-0xfeffcfff

This step is required to free up the 0xff000000-0xffffffff (16MB) range
for use with bios.bin.

The KVM kernel change depends upon a change to kvm/bios/rombios.c so the bios
INT15-E820 function will properly reserve the new location.
