Applications may query the back buffer age to efficiently perform
partial updates. Generally the application will keep a fixed length
damage history, and use this to calculate what needs to be redrawn
based on the age of the back buffer it's about to render to.
If presented with a buffer that has an age greater than the
length of the damage history, the application will likely have
to completely repaint the buffer.
Our current buffer selection strategy is to pick the first available
buffer without considering its age. If an application frequently
manages to fit within two buffers but occasionally requires a third,
this extra buffer will almost always be old enough to fall outside
of a reasonably long damage history, and require a full repaint.
This patch changes the buffer selection behaviour to prefer the oldest
available buffer.
By selecting the oldest available buffer, the application will likely
always be able to use its damage history, at a cost of having to
perform slightly more work every frame. This is an improvement if
the cost of a full repaint is heavy, and the surface damage between
frames is relatively small.
It should be noted that since we don't currently trim our queue in
any way, an application that briefly needs a large number of buffers
will continue to receive older buffers than it would if it only ever
needed two buffers.

As explained in the previous commit, we want to avoid the possibility of

In these two cases, the final allocation size is the product of three values:

In this commit, we move the explicit multiplication to involve only the
compile-time constants, preventing any overflow from that multiplication, (and
allowing calloc to catch any potential overflow from the remainining implicit
multiplication).

The kms-dri swrast driver cannot share buffers using the GEM,
so it must tell the loader to disable extensions relying on
that, without disabling the image DRI extension altogether
(which would prevent the loader from working at all).
This requires a new gallium capability (which is queried on
the pipe_screen and for swrast drivers it's forwarded to the
winsys), and requires a new version of the DRI image extension.
[Emil Velikov]
- Rebased on top of gallium-dri megadrivers.
- Drop PIPE_CAP_BUFFER_SHARE and sw_winsys::get_param hook.
The can_share_buffer cap is set at InitScreen. We use a different
InitScreen (and thus value for the cap) function for kms_dri, due to
deeper differences originating from dri megadrivers.
