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 * Patch 4 inits pcode on different gt's * Patch 5 adds a couple of pcode helpers * Patch 6 uses the new pcode functions to retrieve media RP0/RPn freq * Patch 7 fixes memory leaks in the previous per-gt sysfs implementation and some code refactoring
Patches 1, 3 and 5 have been merged to drm-intel-next, and then branch cross-merged into drm-intel-gt-next.
You can try re-sending the rest of the series now and see if that goes smoothly.

IGT tests for this new functionality have also been posted at: https://patchwork.freedesktop.org/series/103175/ Test-with: 20220513011500.73460-1-ashutosh.dixit@xxxxxxxxx v2: Fixed commit author on patches 5 and 6 (Rodrigo) Added new patch 4 v3: Expose pcode functions in terms of uncore rather than gt (Jani/Rodrigo) v4: Retain previous pcode function names to eliminate needless #defines (Rodrigo) v5: Add new patch 4 and remove last two patches in the v4 series which will be submitted later. Other mostly minor fixes from code review v6: Identical to v5, only update "Test-with:" since CI did not pick up previous "Test-with:" probably because it was old Cc: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxxxxxxxx> Cc: Andi Shyti <andi.shyti@xxxxxxxxxxxxxxx> Cc: Jani Nikula <jani.nikula@xxxxxxxxx> Ashutosh Dixit (5): 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: Init pcode on different gt's drm/i915/gt: Fix memory leaks 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/display/hsw_ips.c | 4 +- drivers/gpu/drm/i915/display/intel_bw.c | 6 +- drivers/gpu/drm/i915/display/intel_cdclk.c | 16 +- .../drm/i915/display/intel_display_power.c | 2 +- .../i915/display/intel_display_power_well.c | 4 +- drivers/gpu/drm/i915/display/intel_hdcp.c | 2 +- drivers/gpu/drm/i915/gt/intel_gt.c | 1 + drivers/gpu/drm/i915/gt/intel_gt_pm_debugfs.c | 4 +- drivers/gpu/drm/i915/gt/intel_gt_regs.h | 1 + drivers/gpu/drm/i915/gt/intel_gt_sysfs.c | 29 ++- drivers/gpu/drm/i915/gt/intel_gt_sysfs.h | 6 +- drivers/gpu/drm/i915/gt/intel_gt_sysfs_pm.c | 177 ++++++++++++++++++ drivers/gpu/drm/i915/gt/intel_gt_types.h | 3 + drivers/gpu/drm/i915/gt/intel_llc.c | 3 +- drivers/gpu/drm/i915/gt/intel_rc6.c | 4 +- drivers/gpu/drm/i915/gt/intel_rps.c | 4 +- drivers/gpu/drm/i915/gt/selftest_llc.c | 2 +- drivers/gpu/drm/i915/gt/selftest_rps.c | 2 +- .../drm/i915/gt/uc/abi/guc_actions_slpc_abi.h | 6 + drivers/gpu/drm/i915/gt/uc/intel_guc_slpc.c | 20 ++ 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_driver.c | 20 +- drivers/gpu/drm/i915/i915_drv.h | 2 + drivers/gpu/drm/i915/i915_pci.c | 2 + drivers/gpu/drm/i915/i915_reg.h | 11 ++ drivers/gpu/drm/i915/i915_sysfs.c | 2 + drivers/gpu/drm/i915/intel_device_info.h | 1 + drivers/gpu/drm/i915/intel_dram.c | 2 +- drivers/gpu/drm/i915/intel_pcode.c | 93 +++++---- drivers/gpu/drm/i915/intel_pcode.h | 20 +- drivers/gpu/drm/i915/intel_pm.c | 10 +- 32 files changed, 363 insertions(+), 100 deletions(-)
