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.
