Proposal to standardise the fdinfo text format as optionally output by DRM drivers. Idea is that a simple but, well defined, spec will enable generic userspace tools to be written while at the same time avoiding a more heavy handed approach of adding a mid-layer to DRM. i915 implements a subset of the spec, everything apart from the memory stats currently, and a matching intel_gpu_top tool exists. Open is to see if AMD can migrate to using the proposed GPU utilisation key-value pairs, or if they are not workable to see whether to go vendor specific, or if a standardised alternative can be found which is workable for both drivers. Same for the memory utilisation key-value pairs proposal. v2: * Update for removal of name and pid. v3: * 'Drm-driver' tag will be obtained from struct drm_driver.name. (Daniel) v4: * Added drm-engine-capacity- tag.
