Subject: [PATCH 0/3] xen: optimize xenbus performance
Date: Fri, 6 Jan 2017 16:05:41 +0100 [thread overview]
Message-ID: <20170106150544.10836-1-jgross@suse.com> (raw)
The xenbus driver used for communication with Xenstore (all kernel
accesses to Xenstore and in case of Xenstore living in another domain
all accesses of the local domain to Xenstore) is rather simple
especially regarding multiple concurrent accesses: they are just being
serialized in spite of Xenstore being capable to handle multiple
parallel accesses.
Clean up the external interface(s) of xenbus and optimize its
performance by allowing multiple concurrent accesses to Xenstore.
Juergen Gross (3):
xen: clean up xenbus internal headers
xen: modify xenstore watch event interface
xen: optimize xenbus driver for multiple concurrent xenstore accesses
