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 IGT tests for this new functionality have also been posted at: https://patchwork.freedesktop.org/series/103175/ Test-with: 20220426194111.5990-1-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.
