Subject: [PATCH v3 00/10] Nested VMX: Add virtual EPT & VPID support to L1 VMM
Date: Thu, 20 Dec 2012 23:43:41 +0800 [thread overview]
Message-ID: <1356018231-26440-1-git-send-email-xiantao.zhang@intel.com> (raw)
From: Zhang Xiantao <xiantao.zhang@intel.com>
With virtual EPT support, L1 hyerpvisor can use EPT hardware for L2 guest's memory virtualization.
In this way, L2 guest's performance can be improved sharply.
According to our testing, some benchmarks can show > 5x performance gain.
Changes from v1:
Update the patches according to Tim's comments.
1. Patch 03: Enhance the virtual EPT's walker logic.
2. Patch 04: Add a new field in struct p2m_domain, and use it to store
EPT-specific data. For host p2m, it saves L1 VMM's EPT data,
and for nested p2m, it saves nested EPT's data 3. Patch 07: strictly check host's p2m access type.
4. Other patches: some whitespace mangling fixes.
Changes form v2:
Addressed comments from Jan and Jun:
1. Add Acked-by message for reviewed patches by Tim.
2. Fixed one whilespace mangling issue in PATCH 08
3. Add some comments to describe the meaning of
the return value of hvm_hap_nested_page_fault
in PATCH 05.
4. Add the logic for handling default case of two switch
statements.
Zhang Xiantao (10):
nestedhap: Change hostcr3 and p2m->cr3 to meaningful words
nestedhap: Change nested p2m's walker to vendor-specific
nested_ept: Implement guest ept's walker
EPT: Make ept data structure or operations neutral
nEPT: Try to enable EPT paging for L2 guest.
nEPT: Sync PDPTR fields if L2 guest in PAE paging mode
nEPT: Use minimal permission for nested p2m.
nEPT: handle invept instruction from L1 VMM
nVMX: virutalize VPID capability to nested VMM.
nEPT: expost EPT & VPID capablities to L1 VMM
