The libdrm tree contains configuration files for EditorConfig (https://editorconfig.org/); since you're using Eclipse, https://github.com/ncjones/editorconfig-eclipse should help. I run amdgpu_test as part of my daily build/test script during lunch break; when I came back today, I was greeted by a GFX hang of the Bonaire in my development box due to this test. Please disable it for all pre-GFX8 ASICs. Ideally, it should also check at runtime that GPU recovery is actually enabled, as that still isn't the case by default except with bleeding edge amdgpu kernel code.

There is a pplib messaging related failure currently during GPU reset. I will put this issue on my TODO list for later time after handling more prioritized stuff and will disable the deadlock test suite for all non dGPU gfx8/9 ASICs until then.

Also, disable the suite for all APU ASICs until GPU reset issues for them will be resolved and GPU reset recovery will be enabled by default.
