[Spice-devel] [PATCH 0/2] Smartly allocate memory on the two BARs

[Frediano Ziglio]

Currently a single type of surface is allocated in a specific BAR.
This also changes from userspace driver to the kernel one.
This way it could happen that allocation are failing even if there are
plenty of space in the other BAR.
For instance this can happen trying to change resolution as the old and
the new virtual screen is supposed to be contained in a single BAR.
The change allows allocation to occur in the BAR not being the default
for a surface type.

The patches prove to be really stable. I tested setting quite small BARs
(one or the oher) or changing default allocation BAR and continued working.
Setting large resolution is working fine while without these patches fails
for not so big BAR sizes.

Changes from previous version:
- remove RFC;
- added signed-off-by;
- added prefix in commit title;
- rebased.
