Hello Mesa developers,
Following the discussion from
https://lists.freedesktop.org/archives/mesa-dev/2017-April/153137.html
A check was added to ensure that X11 display can be locked. It should be enough
to ensure thread safety between X11 and glthread.
I also did the check on DRI3 as I'm not 100% sure that it is really thread safe.
------------------------------------
v2: based on Nicolai/Matt reviews
Add a check on DRI extension version
Use C comments :)
v3: based on Emil reviews
Split the initial first patch into 3 sub patches dri extension / glx / egl
Improve error message
Improve code readability
Just include libX11 on EGL protected by ifdef
Thanks you for all the review comments.
Best regards,
Gregory Hainaut (4):
dri: Extend __DRIbackgroundCallableExtensionRec to include a callback
that checks for thread safety
glx: implement __DRIbackgroundCallableExtension.isThreadSafe
egl: implement __DRIbackgroundCallableExtension.isThreadSafe
glthread/gallium: require safe_glthread to start glthread
