Subject: [PATCH v1 0/2] migration: Skip the first dirty sync
Date: Sat, 9 Nov 2024 12:59:40 +0800 [thread overview]
Message-ID: <cover.1731128180.git.yong.huang@smartx.com> (raw)
The first iteration's RAMBlock dirty sync can be omitted because QEMU
always initializes the RAMBlock's bmap to all 1s by default.
Prior to that, a pre-requisite patch was offered to maintain the free
page optimizing behavior.
For more details, please refers to:
https://lore.kernel.org/qemu-devel/CAK9dgmZSmoydJkFQP5VXfN21etMZc_bNq51R+if08F+NTApN_A@mail.gmail.com/T/#t
Please review, thanks
Yong
