drm/i915/gt: Expose engine properties via sysfs Preliminary stub to add engines underneath /sys/class/drm/cardN/, so that we can expose properties on each engine to the sysadmin. To start with we have basic analogues of the i915_query ioctl so that we can pretty print engine discovery from the shell, and flesh out the directory structure. Later we will add writeable sysadmin properties such as per-engine timeout controls. An example tree of the engine properties on Braswell: /sys/class/drm/card0 └── engine ├── bcs0 │ ├── capabilities │ ├── class │ ├── instance │ ├── known_capabilities │ └── name ├── rcs0 │ ├── capabilities │ ├── class │ ├── instance │ ├── known_capabilities │ └── name ├── vcs0 │ ├── capabilities │ ├── class │ ├── instance │ ├── known_capabilities │ └── name └── vecs0 ├── capabilities ├── class ├── instance ├── known_capabilities └── name v2: Include stringified capabilities v3: Include all known capabilities for futureproofing. v4: Combine the two caps loops into one v5: Hide underneath Kconfig.unstable for wider discussion Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Acked-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Tested-by: Steve Carbonari <steven.carbonari@intel.com> Reviewed-by: Steve Carbonari <steven.carbonari@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200228131716.3243616-1-chris@chris-wilson.co.uk 2020-02-28 20:17:10 +07:00			`/* SPDX-License-Identifier: MIT */`
