GNOME Bugzilla – Bug 742254
Use tricks like hw overlays and buffer-age to save power
Last modified: 2021-07-05 13:51:53 UTC
Hi, Reading this Rob Clark's statement (he's freedreno developer) [1], it seems that Wayland offers some tricks to save power : it would be great if Mutter could use them. Thanks ! [1] "When there are wayland compositors which can utilize hw overlays I would expect big savings in some scenarios. It is pretty common perf/power trick done on mobile devices. That and taking advantage of buffer-age." - see http://www.phoronix.com/forums/showthread.php?111654-Does-Using-GNOME-On-Wayland-Save-Power&p=461218#post461218 (see also this other statement although : http://www.phoronix.com/forums/showthread.php?111654-Does-Using-GNOME-On-Wayland-Save-Power&p=461282#post461282)
We do use buffer-age. And overlays are waiting until he's done with atomic :)
GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org. As part of that, we are mass-closing older open tickets in bugzilla.gnome.org which have not seen updates for a longer time (resources are unfortunately quite limited so not every ticket can get handled). If you can still reproduce the situation described in this ticket in a recent and supported software version, then please follow https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines and create a new ticket at https://gitlab.gnome.org/GNOME/mutter/-/issues/ Thank you for your understanding and your help.
