Subject: [PATCH v3 0/7] Allow setting up shared memory areas between VMs from xl config files
Date: Thu, 19 Oct 2017 10:36:28 +0800 [thread overview]
Message-ID: <20171019023635.19812-1-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
v3:
* Added the docs
* Changed the order of patches to reflect their internal dependencies
* Fixed the error handling when memory mapping are done but the xs
trasaction fails
* Changed the xsm hooks to lookup the current domain themselves instead of
getting it as a parameter
Cheers,
Zhongze Liu (7):
libxc: add xc_domain_remove_from_physmap to wrap
XENMEM_remove_from_physmap
xsm: flask: change the dummy xsm policy and flask hook for
map_gmfn_foregin
libxl: introduce a new structure to represent static shared memory
regions
libxl: support mapping static shared memory areas during domain
creation
libxl: support unmapping static shared memory areas during domain
destruction
libxl:xl: add parsing code to parse "libxl_static_sshm" from xl config
files
docs: documentation about static shared memory regions
