You can see all options with `man amdgpu` or `man radeon`, etc. > 5. So before running the program from a console, I do "export GALLIUM_HUD=1" > or "GALLIUM_HUD=1;./my_program"? I don't suspect filled RAM as the game's > process doesn't seem to leak memory... I do however suspect filled VRAM. Do `GALLIUM_HUD=help glxgears` it would print all available graphs and the syntax. Here is what I used last time: export GALLIUM_HUD=\ ".dfps+cpu+GPU-load+temperature,.dGTT-usage+VRAM-usage,num-compilations+num-shaders-created;"\ "primitives-generated+draw-calls,samples-passed+ps-invocations+vs-invocations,buffer-wait-time;"\ "CS-thread-busy+gallium-thread-busy,dma-calls+cp-dma-calls,num-bytes-moved;"\ "num-vs-flushes+num-ps-flushes+num-cs-flushes+num-CB-cache-flushes+num-DB-cache-flushes" > 6. What is the Kernel parameter for CMA please? It doesn't seem to be an > amdgpu setting so I assume it's separate. "cma=0 iommu=off" You can look in linux-source/Documentation/admin-guide/kernel-parameters.txt
