Subject: [PATCH] Add necessary bits to pvops Linux for mapping paged-out pages
Date: Fri, 16 Dec 2011 22:22:18 -0500 [thread overview]
Message-ID: <1324092141-9730-1-git-send-email-adin@scannell.ca> (raw)
I've ported a couple of patches to the Linux pvops kernel that are necessary
for correctly running domains with paging. In a nutshell: in the case of a
foreign attempt to map a paged-out page, the correct error code will now be
propogated up to libxc, which will already handle it correctly.
This required an implementation of mmap_batch_v2.
I've tested it using a highly-paged domain and everything looks okay (qemu will
receive the appropriate error via the mmap_batch_v2 and retry).
(My apologies if anyone/everyone receives this set of patches more than once,
I've had some trouble with both my connection dying and guilt freaking out
while I'm sending, leaving things in a bit of an unknown state.)
