Bug ID: 99955 Summary: [r600g] GPU load always displayed at 100% with GALLIUM_HUD=GPU-load Product: Mesa Version: git Hardware: All OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: megwattt@gmail.com QA Contact: dri-devel@lists.freedesktop.org
Hello,
The GPU-load graph from GALLIUM_HUD will always be at 100%, no matter what application is launched (even glxgears with vblank_mode=3). I tested that on my Radeon HD 5770.
This regression is caused by commit b8f3b00742eab6ee1868407b876f69195a51f3b6 : gallium/radeon: include SDMA in the GPU load query.
It doesn't seems to affect radeonsi, as the GPU-load results on a TOPAZ XT chip are more reasonable (~5% with the same test).

--- Comment #1 from Hleb Valoshka 375gnu@gmail.com --- This bug affects radeonsi as well (HW - 7750, kernel - Linux 4.10.0-rc8, amdgpu kernel driver).
When this commit (b8f3b007) is reverted, then hud shows a correct value.

I am still experiencing this issue on a R9-390 GPU with Mesa git-469da09.
What kernel are you using?

- radeontop is working OK.

Just a note about the migration process: Bugzilla migration to https://gitlab.freedesktop.org/mesa/mesa/issues/598 is failing to preserve newline characters found in this bug report. This seems to be the case only when the line starts with an $.
