Subject: [PATCH 00 of 10] tools/xenpaging: cleanups and performance improvements
Date: Mon, 30 Jan 2012 16:59:23 +0100 [thread overview]
Message-ID: <patchbomb.1327939163@probook.site> (raw)
This series adjusts the error reporting in the various code paths, with
the intention that fatal errors can be detected by callers and handled
properly. During my performance analysis with callgrind I found and
fixed a few bottlenecks in the page-in code paths.
Patches 1, 2 and 3 were already sent earlier. I'm including them here
again since later patches depend on them.
Changes:
xenpaging: use flat index for pagefile and page-in requests
xenpaging: no poll timeout while page-out is in progress
xenpaging: mmap guest pages read-only
xenpaging: reduce number of qemu cache flushes
xenpaging: move nominate+evict into single function
xenpaging: improve performance in policy_choose_victim
xenpaging: unify error handling
xenpaging: move pagefile filedescriptor into struct xenpaging
xenpaging: move page_buffer into struct xenpaging
xenpaging: implement stack of free slots in pagefile
