Description:
alim115 commented on 2017-09-15 04:52 (edited on 2017-09-15 06:05 by alim115) I did a bisect on mesa 17.2 and tracked down the change that broke vaapi. The change is specific to Gen8+ GPUs. It affects Broadwell GPUs for sure and possibly Skylake+ GPUs. https://cgit.freedesktop.org/mesa/mesa/commit/?h=17.2&id=8ec5a4e4a4a32f4de351c5fc2bf0eb615b6eef1b @maximbaz If you have time to make your own mesa-17.2 build, can you try reversing the patch (only the third block needs to be backed out: brw_state_upload.c)? No one else commenting that they have the issue. It fixes the vaapi problem on my laptop and doesn't seem to break anything else. Additional info: * package version(s) 17.2 * config and/or log files etc. Steps to reproduce: 1. install mesa-17.2 2. install chromium-vaapi-bin 3. enable vaapi accelaration 4. open a HTML5 video 5. expected playback smoothly, but actually freeze the whole process |

If the issue is still there - do open a bug against Mesa see [1].
Informing the developers about this regression.

The problem can be fixed by downgrading the mesa package to mesa-17.2.1-3-x86_64 and leaving all other packages as they are.
Processor is Intel Core i5, Clarkdale i5-660 @ 3.3GHz x 2 (Westmere architektur) and integrated GPU with HD Graphics (Ironlake).
