Changlog v3:
Those changes all form Avi's suggestion, thanks.
- use smart way to fix the bug in patch 1
- remove duplicates code in patch 5
- check error code and fix forgot release page in patch 9
- sync shadow pages in a batch instead of one by one
And, there is one TODO thing:
Marker shadow page as unsync at create time avoid write-protect,
this idea is from Avi:
|Another interesting case is to create new shadow pages in the unsync state.
|That can help when the guest starts a short lived process: we can avoid write
|protecting its pagetables completely
I'll send the patch out after this patchset applied.
Changlog v2:
- when level is PT_DIRECTORY_LEVEL, the 'offset' should be
'role.quadrant << 8', thanks Avi for point it out
- keep invlpg code in paging_tmpl.h address Avi's suggestion
- split kvm_sync_page() into kvm_sync_page() and kvm_sync_page_transient()
to clarify the code address Avi's suggestion
