Subject: [PATCH 0 of 5] tools: console ring fixes
Date: Wed, 20 Feb 2013 18:05:30 +0000 [thread overview]
Message-ID: <patchbomb.1361383530@andrewcoop.uk.xensource.com> (raw)
Hello,
The following set of patches came about when trying to fix the 32K limitation
with stub_xc_readconsolering() in the ocaml bindings.
Patch 1 is a hypervisor patch adding a new SYSCTL hypercall to query the size
of the console ring, which is fixed but otherwise inaccessible after boot.
Patches 2 thru 5 are tools patches:
* Patch 2 adds a libxc function to use the new SYSCTL hypercall.
* Patch 3 implements an alternative xc_readconsolering() to prevent bounce
buffering.
* Patch 4 uses the preceding patches to fix the implementation of
stub_xc_readconsolering() in the ocaml bindings.
* Patch 5 is a misc threading fix in the ocaml bindings, discovered when
trying to fix the console functionality.
This patch set has been compile-tested on unstable, and functionally tested
via backport to 4.2 (which was only one whitespace fuzz issue and no code
change).
