[Xen-devel] [PATCH V3 0/3] Fix VGA logdirty related display freezes with altp2m

[Razvan Cojocaru <rcojocaru@xxxxxxxxxxxxxxx>]

Hello,

This series aims to prevent the display from freezing when
enabling altp2m and switching to a new view (and assorted problems
when resizing the display). Since the last version of the series,
what was previously the second (and last) patch has been split in
two patches, the first of which only concerns itself with rangeset
allocation / deallocation / initialization.

The first patch propagates ept.ad changes to all active altp2ms,
the second one allocates and initializes a new logdirty rangeset for
each new altp2m, and the third propagates (under lock) changes to all
p2ms.

[PATCH V3 1/3] x86/altp2m: propagate ept.ad changes to all active altp2ms
[PATCH V3 2/3] x86/mm: allocate logdirty_ranges for altp2ms
[PATCH V3 3/3] x86/altp2m: fix display frozen when switching to a new view early


Thanks,
Razvan
