Subject: [PATCH 22/50] egl/wayland: flush the drawable before blitting
|
|
|
|
Flush the drawable before blitting in the "is_different_gpu" case when
|
|
swapping buffers, and pass the flush flag to the blitImage call. The
|
|
change brings the code into line with the way the DRI3 GLX code works.
|
|
|
|
For the PowerVR driver, the drawable parameters that will be used in
|
|
the flush have been obtained previously, including any native fence
|
|
associated with the blit source. The blit will result in a new native
|
|
fence for the source, and make the one in the drawable parameters
|
|
invalid.
