drm/i915/mtl/gsc: Add a gsc_info debugfs Add a new debugfs to dump information about the GSC. This includes: - the FW path and SW tracking status; - the release, security and compatibility versions; - the HECI1 status registers. Note that those are the same registers that the mei driver dumps in their own status sysfs on DG2 (where mei owns the GSC). To make it simpler to loop through the status register, the code has been update to use a PICK macro and the existing code using the regs had been adapted to match. v2: fix includes and copyright dates (Alan) v3: actually fix the includes Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Alan Previn <alan.previn.teres.alexis@intel.com> Cc: John Harrison <John.C.Harrison@Intel.com> Reviewed-by: Alan Previn <alan.previn.teres.alexis@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230612181529.2222451-5-daniele.ceraolospurio@intel.com

drm/i915/gt: Create per-gt debugfs files To support multi-GT configurations, we need to generate independent debug files for each GT. To achieve this create a separate directory for each GT under the debugfs directory. For instance, in a system with two GTs, the debugfs structure would look like this: /sys/kernel/debug/dri └── 0 ├── gt0 │ ├── drpc │ ├── engines │ ├── forcewake │ ├── frequency │ └── rps_boost └── gt1 : ├── drpc : ├── engines : ├── forcewake ├── frequency └── rps_boost Signed-off-by: Andi Shyti <andi.shyti@linux.intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Radhakrishna Sripada <radhakrishna.sripada@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230318203616.183765-2-andi.shyti@linux.intel.com

drm/i915: rename debugfs_gt files We shouldn't be using debugfs_ namespace for this functionality. Rename debugfs_gt.[ch] to intel_gt_debugfs.[ch] and then make functions, defines and structs follow suit. While at it and since we are renaming the header, sort the includes alphabetically.

drm/i915/uc: Extract uc usage details into separate debugfs It has been pointed out that information about HuC usage doesn't belong in guc_info debugfs. Let's move "supported/used/wanted" matrix to a separate debugfs file, keeping guc_info strictly about GuC.

drm/i915/uc: Move uC debugfs to its own folder under GT uC is a component of the GT, so it makes sense for the uC debugfs files to be in the GT folder. A subfolder has been used to keep the same structure we have for the code. v2: use intel_* prefix (Jani), rebase on new gt_debugfs_register_files, fix permissions for writable debugfs files. v3: Rename files (Michal), remove blank line (Jani), fix sparse warns.
