Some recent Intel dGfx platforms allow media IP to work at a different frequency from the base GT. This patch series exposes sysfs controls for this functionality in the new per-gt sysfs. Some enhancements and fixes to previous per-gt functionality are also included to complete the new functionality: * Patches 1 and 2 implement basic sysfs controls for media freq * Patches 3 and 4 extend previous pcode functions for multiple gt's and patch 5 adds a couple of pcode helpers * Patch 6 uses the new pcode functions to retrieve media RP0/RPn frequencies * Patch 7 fixes memory leaks in the previous per-gt sysfs implementation and some code refactoring * Patch 8 creates a gt/gtN/.defaults directory to expose default RPS parameter values in the per-gt sysfs * Patch 9 adds the default value for media_freq_factor to gt/gtN/.defaults
IGT tests for this new functionality have also been posted at: https://patchwork.freedesktop.org/series/102664/ Test-with: 85c51c99da76e3fe286ed28e80fa964e148f6020.1650435058.git.ashutosh.di...@intel.com v2: Fixed commit author on patches 5 and 6 (Rodrigo) Added new patch 4 Cc: Rodrigo Vivi <rodrigo.v...@intel.com> Cc: Joonas Lahtinen <joonas.lahti...@linux.intel.com> Cc: Andi Shyti <andi.sh...@intel.com> Ashutosh Dixit (7): drm/i915: Introduce has_media_ratio_mode drm/i915/gt: Add media freq factor to per-gt sysfs drm/i915/pcode: Extend pcode functions for multiple gt's drm/i915/gt: Convert callers to user per-gt pcode functions drm/i915/gt: Fix memory leaks in per-gt sysfs drm/i915/gt: Expose per-gt RPS defaults in sysfs drm/i915/gt: Expose default value for media_freq_factor in per-gt sysfs Dale B Stimson (2): drm/i915/pcode: Add a couple of pcode helpers drm/i915/gt: Add media RP0/RPn to per-gt sysfs drivers/gpu/drm/i915/gt/intel_gt.c | 1 + drivers/gpu/drm/i915/gt/intel_gt_pm_debugfs.c | 6 +- drivers/gpu/drm/i915/gt/intel_gt_regs.h | 1 + drivers/gpu/drm/i915/gt/intel_gt_sysfs.c | 41 ++- drivers/gpu/drm/i915/gt/intel_gt_sysfs.h | 12 +- drivers/gpu/drm/i915/gt/intel_gt_sysfs_pm.c | 246 ++++++++++++++++++ drivers/gpu/drm/i915/gt/intel_gt_types.h | 14 + drivers/gpu/drm/i915/gt/intel_llc.c | 9 +- drivers/gpu/drm/i915/gt/intel_rc6.c | 4 +- drivers/gpu/drm/i915/gt/intel_rps.c | 9 +- drivers/gpu/drm/i915/gt/selftest_llc.c | 4 +- drivers/gpu/drm/i915/gt/selftest_rps.c | 4 +- .../drm/i915/gt/uc/abi/guc_actions_slpc_abi.h | 6 + drivers/gpu/drm/i915/gt/uc/intel_guc_slpc.c | 39 ++- drivers/gpu/drm/i915/gt/uc/intel_guc_slpc.h | 1 + .../gpu/drm/i915/gt/uc/intel_guc_slpc_types.h | 3 + drivers/gpu/drm/i915/i915_drv.h | 2 + drivers/gpu/drm/i915/i915_pci.c | 2 + drivers/gpu/drm/i915/i915_reg.h | 18 ++ drivers/gpu/drm/i915/i915_sysfs.c | 2 + drivers/gpu/drm/i915/intel_device_info.h | 1 + drivers/gpu/drm/i915/intel_pcode.c | 136 ++++++---- drivers/gpu/drm/i915/intel_pcode.h | 39 ++- 23 files changed, 499 insertions(+), 101 deletions(-) -- 2.34.1
