Subject: [PATCH v11 0/2] x86/viridian improvements
Date: Tue, 16 Sep 2014 18:18:47 +0100 [thread overview]
Message-ID: <1410887929-7748-1-git-send-email-paul.durrant@citrix.com> (raw)
This patch series incorporates several improvements to the code
supporting viridian (i.e. hyper-v compatible) enlightenments for
Windows guests:
Patch #1 series lays the foundations for adding new viridian
enlightenments such that they can be optionally enabled, and not
immediately exposed to a guest across a save/restore boundary.
Patch #2 adds support for the 'Partition Time Reference Counter'
enlightenment.
v2:
- Addressed comments from Jan Beulich
- Added patch #2
v3:
- Addressed comments from Andrew Cooper and Jan Beulich
- Re-worked patch #2
- Simplified patch #3 to use guest TSC
v4:
- Added missing domain info to printks in patch #2
v5:
- Clarified comment of patch #1 as suggested by David Vrabel
- More logging tweaks in patch #2 as suggested by Andrew Cooper
v6:
- Dropped previous patch to reduce logging verbosity as it has been
applied
- Toolstack changes only:
- New libxl_integer_list and libxl_viridian_enlightenment types to
avoid passing of strings between xl and libxl, as requested by
Ian Jackson.
- Retained and deprecated viridian defbool rather than replacing it
to avoid API breakage pointed out by Ian Campbell. Enlightenment list
is now in a new hvm-only viridian_enlightenments field of the build
info.
v7:
- Changes to patch #2 only:
- Reference time calculation now makes use of struct time_scale and
set_time_scale and scale_delta functions to avoid overflow issues
pointed out by Christoph Egger.
v8:
- Changes to patch #2 only:
- Fixed 32- to 64-bit type promotion issue as pointed out by
Jan Beulich
v9:
- Changes to ocaml stubs in patch #1 only
- There was a missing calloc in the libxl_integer_list ocaml stubs
v10:
- Toolstack changes only:
- Re-worked toolstack code after discussion with Ian C and Ian J.
See http://lists.xen.org/archives/html/xen-devel/2014-09/msg00416.html
v11:
- Toolstack changes only:
- Re-worked toolstack code after further discussion with Ian J.
