Subject: [PATCH] drm/vc4: Add async update support for cursor planes
|
|
|
|
Now that cursors are implemented as regular planes, all cursor
|
|
movements result in atomic updates. As the firmware-kms driver
|
|
doesn't support asynchronous updates, these are synchronous, which
|
|
limits the update rate to the screen refresh rate. Xorg seems unaware
|
|
of this (or at least of the effect of this), because if the mouse is
|
|
configured with a higher update rate than the screen then continuous
|
|
mouse movement results in an increasing backlog of mouse events -
|
|
cue extreme lag.
|
|
|
|
Add minimal support for asynchronous updates - limited to cursor
|
|
planes - to eliminate the lag.
|
|
