How about an interface to change the timeout on a per engine (gfx, compute, dma, etc.) basis?
amdgpu.lockup_timeout=<global>,<gfx>,<compute>,<sdma>,<decode>,<encode>
if only one parameter is given, we change it globably. If more are given, we override the global one. Could also do a sysfs interface to change it on the fly.

But I do not think we can change existing module parameter. Right? Right. Also, there are already too many amdgpu module parameters, we should try to remove some rather than adding new ones for every little thing that could be tweaked. :) One possibility might be to optionally allow passing multiple values to lockup_timeout, e.g. amdgpu.lockup_timeout=10000,0 The first value would need to have the same meaning as now for backwards compatibility. -- Earthling Michel Dänzer | https://www.amd.com Libre software enthusiast | Mesa and X developer _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx |
