From: Xiao Guangrong on 6 May 2010 05:40 Changlog v4: - fix the bug that reported by Marcelo - fix the race in invlpg code 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 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
