drm: Document fdinfo format specification
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.
