Subject: [PATCH v2 0/6] Allow setting up shared memory areas between VMs from xl config files
Date: Sun, 27 Aug 2017 16:36:09 +0800 [thread overview]
Message-ID: <20170827083615.15712-1-blackskygg@gmail.com> (raw)
This series implements the new xl config entry proposed in [1]. Users can use
the new config entry to statically setup shared memory areas among VMs that
don't have grant table support so that they could communicate with each other
through the static shared memory areas.
[1] Proposla to allow setting up shared memory areas between VMs from xl config file:
https://lists.xen.org/archives/html/xen-devel/2017-08/msg03242.html
v2:
* fixed several code style issues.
* introduce MMU__SHARE_MEM in flask av permissions, and add a check to this.
permission in the flask hook for xsm_map_gmfn_foreign.
* support rolling back during creation on partial failure.
* refcounting the sshm path instead of using "alive" and "zombie" to label the
master and counting the slaves.
Cheers,
