Hi,
this is the third version of the patches for KVM to support 1GB pages. Changes
to the last version include:
- changed reporting of 1GB page support to userspace to use
SUPPORTED_CPUID ioctl
- added support for 1GB pages to the software page walker code too
This code still only can make use of 1GB pages with nested paging enabled. I
will give the shadow paging code another debug round soon. Please comment or
consider to apply these patches.
Thanks,
Joerg
