There is new patch-status QA check in oe-core: https://git.openembedded.org/openembedded-core/commit/?id=76a685bfcf927593eac67157762a53259089ea8a This is temporary work around just to hide _many_ warnings from optional patch-status (if you add it to WARN_QA). This just added Upstream-Status: Pending everywhere without actually investigating what's the proper status. This is just to hide current QA warnings and to catch new .patch files being added without Upstream-Status, but the number of Pending patches is now terrible: Patches in Pending state: 41 (57%) With recent change to enable patch-status not only for all .patch files in oe-core, but for all recipes from oe-core: https://git.openembedded.org/openembedded-core/commit/?id=61a881fdbe8b5a21c6276b8a5d06cc30486b1eb3 this causes bluez5 do_patch failures as reported in: https://lists.openembedded.org/g/openembedded-core/message/183177 Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com>

Subject: [PATCH] Implement triple buffering for wayland
|
|
|
|
Change from double to triple buffering for wayland.
|
|
This enables higher frame rates without tearing artifacts
|
|
by allowing both the glFinish and the buffer release
|
|
interlock to operate without pushing the frame period
|
|
to two vertical intervals
