First off, let me reiterate that this feature would be invaluable as user-space
developers. It's often pretty difficult to figure out the cause of an EINVAL,
we have to ask users to follow complicated instructions [1] to grab DRM logs.
Then have to skim through several megabytes of logs to find

Sean Paul proposed, in:
https://patchwork.freedesktop.org/series/78133/
drm/trace: Mirror DRM debug logs to tracefs
His patchset's objective is to be able to independently steer some of
the drm.debug stream to an alternate tracing destination, by splitting
drm_debug_enabled() into syslog & trace
