In sh_page_fault(), there are some code like following, why we think it is mmio only when paging_vcpu_mode_translate(v)? Thanks Yunhong Jiang /* What mfn is the guest trying to access? */ gfn = guest_l1e_get_gfn(gw.eff_l1e); gmfn = vcpu_gfn_to_mfn(v, gfn); mmio = (is_hvm_domain(d) && paging_vcpu_mode_translate(v) &&

As you know, HVM save/restore broke recently because restored config miss guest memsize that used by xc_hvm_restore to locate some pfn. After discussion, we decided to remove the pfn deduction logic from restore side by adding a general memory layout. I have a patch for it. But then qemu broke, because it also require the memsize to locate the share page. We can''t use the previous

Populate-on-demand: Check pages being returned by the balloon driver This patch series is the second result of my work last summer on decreasing fragmentation of superpages in a guests'' p2m when using populate-on-demand. This patch series is against 4.1; I''m posting it to get feedback on the viability of getting a ported version of this patch into 4.2. As with the previous

This patch series tidies up a few bits ofthe nested p2m code. The main thing it does is reorganize the locking so that most of the changes to nested p2m tables happen only under the p2m lock, and the nestedp2m lock is only needed to reassign p2m tables to new cr3 values. Changes since v1: - a few minor fixes - more sensible flushing policy in p2m_get_nestedp2m() - smoke-tested this time!

This patch series includes a series of bugs related to p2m, ept, and PoD code which were found as part of our XenServer product testing. Each of these fixes actual bugs, and the 3.4-based version of the patch has been tested thoroughly. (There may be bugs in porting the patches, but most of them are simple enough as to make it unlikely.) Each patch is conceptually independent, so they can each

Hi, V6: The only change from V5 is in patch #6: - changed comment to reflect autoxlate - removed a redundant ASSERT - reworked logic a bit so that get_page_from_gfn() is called with NULL for p2m type as before. arm has ASSERT wanting it to be NULL. Tim: patch 4 needs your approval. Daniel: patch 5 needs your approval. These patches implement PVH dom0. Patches 1 and 2

Hi, --- background ---------------------------------------------------- * what the makedumpfile is: To shorten the size of the dumpfile and the time of creating the dumpfile, makedumpfile copies only the necessary pages for analysis to the dumpfile from /proc/vmcore. You can specify the kind of unnecessary pages with dump_level. If you want to shorten the size further, enable the
