Subject: [Qemu-devel] [PATCH 0/2] migration/xbzrle: make xbzrle_encode_buffer little easier
Date: Mon, 10 Jun 2019 11:08:50 +0800 [thread overview]
Message-ID: <20190610030852.16039-1-richardw.yang@linux.intel.com> (raw)
Current xbzrle_encode_buffer() do everything in a big loop, which is a little
difficult for audience to catch the logic.
We can refine the logic with:
* get the length of a run
* encode it
At the same time, I found the encoding and decoding function has some extra
pointer operation. Removing this could save some code space.
