[Xen-devel] [PATCH for-4.12 V13 0/5] Fix VGA logdirty related display freezes with altp2m

[Razvan Cojocaru <rcojocaru@xxxxxxxxxxxxxxx>]

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).

The series introduces p2m_{init,free}_logdirty(), allocates a new
logdirty rangeset for each new altp2m, and  propagates (under lock)
changes to all p2ms.

[PATCH for-4.12 V13 1/5] x86/p2m: allocate logdirty_ranges for altp2ms
[PATCH for-4.12 V13 2/5] x86/p2m: refactor p2m_reset_altp2m()
[PATCH for-4.12 V13 3/5] x86/altp2m: fix display frozen when switching to a new 
view early
[PATCH for-4.12 V13 4/5] p2m: Always use hostp2m when clipping rangesets
[PATCH for-4.12 V13 5/5] p2m: change_type_range: Only invalidate mapped gfns


Thanks,
Razvan
