Subject: [PATCH 0/4] xen: enable EPT A/D bit feature
Date: Tue, 19 Jun 2012 14:28:22 +0800 [thread overview]
Message-ID: <1340087306-6096-1-git-send-email-xudong.hao@intel.com> (raw)
Extended Page Tables introduce two bit: access bit and dirty bit, A/D bits
enable VMMs to efficiently implement memory management and page classification
algorithms to optimize VM memory operations.
This series of patches enable EPT dirty bit feature for guest live migration.
PATCH 1/4: Add EPT A/D bits definitions.
PATCH 2/4: Add xen parameter to control A/D bits support, it on by default.
PATCH 3/4: Introduce a log_dirty new function update_dirty_bitmap, which will
only update the log dirty bitmap, but won't clear the EPT page dirty bit.
The function is used by live migration peek round with EPT D bit supported.
PATCH 4/4: enable EPT dirty bit for guest live migration.
