[Mesa-dev] [Bug 89689] [Regression] Weston on DRM backend won't start with new version of mesa
https://bugs.freedesktop.org/show_bug.cgi?id=89689 --- Comment #4 from Daniel Stone dan...@fooishbar.org --- (In reply to Boyan Ding from comment #3) Created attachment 114500 [details] [review] dri/i965: Add XRGB to dri config I hacked the i965 driver and wrote this patch. After applying this to mesa, weston seems to work. I'm not familiar with mesa and I don't know what I'm doing is actually right. Thanks for looking into this. Adding the format to intel_screen_make_configs() definitely seems like the right thing to do to me, but I don't think the depth/stencil changes are required. Have you tried just adding XRGB to the list without modifying depth/stencil? -- You are receiving this mail because: You are the QA Contact for the bug.

https://bugs.freedesktop.org/show_bug.cgi?id=89689 Bug ID: 89689 Summary: [Regression] Weston on DRM backend won't start with new version of mesa Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: EGL Assignee: mesa-dev@lists.freedesktop.org Reporter: stu_...@126.com QA Contact: mesa-dev@lists.freedesktop.org With mesa 10.5.1 and on, weston won't start with DRM backend, saying that it can't find EGL config. I looked into it a little, weston attempts to find XRGB but it only gets ARGB and RGB565. Reverting commit 65c8965d033cf9ade5e6f3c88bda6d247d46af9d: egl: Take alpha bits into account when selecting GBM formats, which has been backported to 10.5 and 10.4 branches eliminates the problem. -- You are receiving this mail because: You are the QA Contact for the bug.

XRGB is what we'd want, since the alpha is not supposed to be interpreted by scanout. Should Weston just take the ARGB from Mesa/GBM and tell KMS it's XRGB? -- You are receiving this mail because: You are the QA Contact for the bug.

https://bugs.freedesktop.org/show_bug.cgi?id=89689 --- Comment #2 from Boyan Ding stu_...@126.com --- It seems that commit 65c8965d is doing nothing wrong and the problem lies in the i965 dri driver. The function intel_screen_make_config in src/mesa/drivers/dri/i965/intel_screen.c only adds ARGB and RGB565 configs. Before commit 65c8965d, the drm platform of EGL wrongly recognizes ARGB as XRGB so weston works okay. Now EGL recognizes things correctly so weston won't find the config it wants. -- You are receiving this mail because: You are the QA Contact for the bug.
