drm/i915/display: move pre-HSW clock gating init to displayMove the remaining pre-HSW display clock gating programming intodisplay.This also drops display register includes from intel_clock_gating.c.Reviewed-by: Jani Nikula Link: https://patch.msgid.link/20260428095104.818360-8-luciano.coelho@intel.comSigned-off-by: Luca Coelho List of files: /linux/drivers/gpu/drm/i915/display/intel_display_clock_gating.h

drm/i915/display: move HSW and BDW clock gating init to displayMove the HSW and BDW display clock gating programming into the displaycode. In this case we need two different helpers, because the commoncode between these two is split in the middle.Reviewed-by: Jani Nikula Link: https://patch.msgid.link/20260428095104.818360-7-luciano.coelho@intel.comSigned-off-by: Luca Coelho List of files: /linux/drivers/gpu/drm/i915/display/intel_display_clock_gating.h

Tue, 28 Apr 2026 11:48:23 +0200

drm/i915/display: move GLK clock gating init to displayMove the GLK-specific display clock gating programming into displayintel_display_clock_gating.c, to remove more dependencies from i915 todisplay registers.Now that all remaining Gen9-family callers moved into display, we canmove the shared Gen9 display clock gating helper into display andremove the old local helper from intel_clock_gating.c.Additionally, the SKL_DE_COMPRESSED_HASH_MODE programming wasprotected by HAS_LLC(), but that's incidental, because in Gen9platforms, only SKL and KBL, for which this workaround applies, haveLLC(). In order not to use HAS_LLC() in display code, we can simplyremove this check from the generic Gen9 function and move theSKL_DE_COMPRESSED_HASH_MODE programming to the KBL and SKL specificfunctions. And, intentionally or not, CFL and CML were also usingthis workaround, because they also have LLC, even though the commentswere only mentioning SKL and KBL. In order not to change anythingfunctionally with this patch, the workaround was also added tointel_display_cfl_init_clock_gating().Reviewed-by: Jani Nikula Link: https://patch.msgid.link/20260428095104.818360-6-luciano.coelho@intel.comSigned-off-by: Luca Coelho List of files: /linux/drivers/gpu/drm/i915/display/intel_display_clock_gating.h
