Re: [Intel-gfx] [PATCH i-g-t 8/8] gputop: Basic vendor agnostic GPU top tool
On 11/05/2022 15:42, Christian König wrote: Just two bugs I've found and you should probably handle: 1. On amdgpu we probably want to filter engines which are not used by an application. This confuses gputop in it's display. E.g. when you have one application using only gfx and the other only sdma both are grouped together which is not correct at all. Grouped as displayed as single line? Pid/name? But either way if they have different client ids they shouldn't be grouped. That would be a bug which I don't quite see in the code so if you could please confirm these details I will look into it some more. The situation where one application uses one engine, and another uses another is exactly present in my "screenshot" from the cover letter so it is supposed to work. 2. Invalid inputs, especially engines with the same name let the tool crash in a segmentation fault. Take this input for example: drm-engine-gfx: 21475769304 ns drm-engine-compute: 0 ns drm-engine-dma: 0 ns drm-engine-dec: 0 ns drm-engine-enc: 0 ns drm-engine-enc_1: 0 ns drm-engine-dec: 0 ns drm-engine-enc: 0 ns drm-engine-jpeg: 0 ns Not really an issue, cause that shouldn't happen in practice, but quite annoying during testing. I can easily make it ignore that sort of a (broken) client, not sure that anything smarter than that would be useful. Regards, Tvrtko Maybe I will find time tomorrow looking over the code. Thanks, Christian.

Borrows a bit of code from intel_gpu_top but for now omits the fancy features like interactive functionality, card selection, client aggregation, sort modes, JSON output and pretty engine names. Also no support for global GPU or system metrics. On the other hand it shows clients from all DRM cards which intel_gpu_top does not do.

[Intel-gfx] [PATCH i-g-t 8/8] gputop: Basic vendor agnostic GPU top tool
From: Tvrtko Ursulin Rudimentary vendor agnostic example of how lib_igt_drm_clients can be used to display a sorted by card and usage list of processes using GPUs. Borrows a bit of code from intel_gpu_top but for now omits the fancy features like interactive functionality, card selection, client aggregation, sort modes, JSON output and pretty engine names. Also no support for global GPU or system metrics. On the other hand it shows clients from all DRM cards which intel_gpu_top does not do.
