drm/i915/gt: make a gt sysfs group and move power management filesmultitile
The GT has its own properties and in sysfs they should be grouped in the 'gt/' directory. Create a 'gt/' directory in sysfs which will contain gt0...gtN directories related to each tile configured in the GPU. Move the power management files inside those directories. The previous power management files are kept in their original root directory to avoid breaking the ABI. They point to the tile '0' and a warning message is printed whenever accessed to. The deprecated interface needs for the CONFIG_SYSFS_DEPRECATED_V2 flag in order to be generated. The new sysfs structure will have a similar layout for the 4 tile case: /sys/.../card0 ├── gt │   ├── gt0 │   │   ├── id │   │   ├── rc6_enable │   │   ├── rc6_residency_ms │   │   ├── rps_act_freq_mhz │   │   ├── rps_boost_freq_mhz │   │   ├── rps_cur_freq_mhz │   │   ├── rps_max_freq_mhz │   │   ├── rps_min_freq_mhz │   │   ├── rps_RP0_freq_mhz │   │   ├── rps_RP1_freq_mhz │   │  └── rps_RPn_freq_mhz . . . . . . │   └── gt3 │   ├── id │   ├── rc6_enable │   ├── rc6_residency_ms │   ├── rps_act_freq_mhz │   ├── rps_boost_freq_mhz │   ├── rps_cur_freq_mhz │   ├── rps_max_freq_mhz │   ├── rps_min_freq_mhz │   ├── rps_RP0_freq_mhz │   ├── rps_RP1_freq_mhz │   └── rps_RPn_freq_mhz ├── gt_act_freq_mhz -+ ├── gt_boost_freq_mhz | ├── gt_cur_freq_mhz | Original interface ├── gt_max_freq_mhz +─-> kept as existing ABI; ├── gt_min_freq_mhz | it points to gt0/ ├── gt_RP0_freq_mhz | └── gt_RP1_freq_mhz | └── gt_RPn_freq_mhz -+ Signed-off-by: Andi Shyti <andi.shyti@linux.intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Sujaritha Sundaresan <sujaritha.sundaresan@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
