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 * Patch 3 extends previous pcode functions for multiple gt's and patch 4 adds a couple of pcode helpers * Patch 5 uses the new pcode functions to retrieve media RP0/RPn frequencies * Patch 6 fixes memory leaks in the previous per-gt sysfs implementation and some code refactoring * Patch 7 creates a gt/gtN/.defaults directory to expose default RPS parameter values in the per-gt sysfs * Patch 8 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: deb07be64c3930945a0e7bd17989fda4ed2e5ece.1649870633.git.ashutosh.dixit@xxxxxxxxx Cc: Rodrigo Vivi <rodrigo.vivi@xxxxxxxxx> Cc: Joonas Lahtinen <joonas.lahtinen@xxxxxxxxxxxxxxx> Cc: Andi Shyti <andi.shyti@xxxxxxxxx> Ashutosh Dixit (8): 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/pcode: Add a couple of pcode helpers drm/i915/gt: Add media RP0/RPn to per-gt sysfs 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 drivers/gpu/drm/i915/gt/intel_gt.c | 1 + 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_rps.c | 3 + .../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 ++- 18 files changed, 483 insertions(+), 84 deletions(-) -- 2.34.1
