Hello, 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. EGL case is more tricky so the pair (X11/libX11) is marked as unsafe. I think it is fine because modern EGL application should rely on XCB (on the X11 platform). ------------------------------------ v2: based on Nicolai/Matt reviews Add a check on DRI extension version Use C comments :) Best regards, Gregory Hainaut (2): glx|egl: allow to test if glthread is safe enough on X11 platform glthread/gallium: require safe_glthread to start glthread include/GL/internal/dri_interface.h | 10 ++++++++ src/egl/drivers/dri2/egl_dri2.c | 34 +++++++++++++++++++++++++++- src/gallium/state_trackers/dri/dri_context.c | 12 ++++++++-- src/glx/dri2_glx.c | 11 ++++++++- src/glx/dri3_glx.c | 10 +++++++- 5 files changed, 72 insertions(+), 5 deletions(-) -- 2.11.0 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
