[PATCH xserver v3 15/24] present: Add window flip mode
Roman Gilg
subdiff at gmail.com
Tue Mar 13 15:00:48 UTC 2018
In contrast to screen flip mode this mode:
* supports flips per windows (these windows currently need to have the same
size as their parent windows with the same pixmap),
* sends pixmap idle signals to the client only after the driver has given
an additional event notify.
This patch only introduces the new mode as a stub. It additionally needs a
driver hook, such that it can get initialized and appropriate cleanup
functions.
