  • Thread-topic: [PATCH] Reload KRs when domain switch
Hi, Dan,

This is next block which made dom0 in nested dtlb miss forever. The
reason is that KR is not reloaded after domain switch, and thus invalid
KRs are used. Several TLB miss related handlers in guest depend on KR7
to walk current page table. Then invalid KR value made everything
messed.

Signed-off-by Kevin Tian <Kevin.tian@xxxxxxxxx>

Thanks,
Kevin
