The restriction about no whitespace, etc, really only applies to the
usage of strings in keys. Values can contain anything (other than
newline).

Add support to dump GEM stats to fdinfo.
v2: Fix typos, change size units to match docs, use div_u64
v3: Do it in core
v4: more kerneldoc
v5: doc fixes
v6: Actually use u64, bit more comment docs

Handle a bit of the boiler-plate in a single case, and make it easier to
add some core tracked stats. This also ensures consistent behavior
across drivers for standardised fields.
v2: Update drm-usage-stats.rst, 64b client-id, rename drm_show_fdinfo
v3: Rebase on drm-misc-next

That section should still be inside "DRM client usage stats" rather than
as a sibling.

Similar to AMD commit
874442541133 ("drm/amdgpu: Add show_fdinfo() interface"), using the
infrastructure added in previous patches, we add basic client info
and GPU engine utilisation for msm.

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.
