Currently, for the purpose of providing output debug/loggging/crc and various
other kinds of data from DRM layer to userspace, we don't have a standard
filesystem, which would suffice for all the usecases. The filesystems used
currently such as debugfs/sysfs have thei

The patch introduces a new pseudo filesystem type, named 'drmfs' which is
intended to house the files for the data generated by drm subsystem that
cannot be accommodated by any of the existing filesystems.

During drm module initialization, drm_core_init initializes the drmfs
filesystem and register this with kernel. A driver specific directory is created
inside drmfs root, and dentry of this directory is saved for subsequent use
by the driver (e.g. i915). The driver can then

In the current scenario, the relay API fit well only with debugfs, due to
availability of parent dentry. Any other existing filesystem was not feasible
for
holding guc logs, due to incompatibility with relay. But this makes the guc_log
file unavailable on the production

Currently, we don't have a stable ABI which can be used for the purpose of
providing output debug/loggging/crc and other such data from DRM.
The ABI in current use (filesystems, ioctls, et al.) have their own
constraints and are intended to output a particular type of

The drmfs filesystem will not be registered standalone during kernel init time,
instead it is intended to be initialized/registered during drm initialization.

This again is dependent on CONFIG_DRMFS being defined.
