I spoke to Paolo about this a while back and thought to post this as RFC while I am thinking of adding some unit tests. Background: ESX refuses to run as L1 if support for EPT execute only isn't found. I am not really sure if it uses it for anything since just advertising the bits seems to work but adding the necessary plumbing seemed like a good idea. Xiao, I took the liberty of adding you based on "git blame" :) Thanks in advance. Bandan Das (4): mmu: add a boolean to indicate host ept execute only support mmu: Update ept specific valid bit values mmu: don't set the present bit unconditionally vmx: advertise support for ept execute only arch/x86/include/asm/kvm_host.h | 2 +- arch/x86/kvm/mmu.c | 22 +++++++++++++++++----- arch/x86/kvm/paging_tmpl.h | 9 +++++++-- arch/x86/kvm/vmx.c | 5 ++++- arch/x86/kvm/x86.c | 2 +- 5 files changed, 30 insertions(+), 10 deletions(-) -- 2.5.5 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
