2024-11-12drm/i915/display: convert HAS_IPS() to struct intel_displayJani Nikula
Convert HAS_IPS() to struct intel_display. Do minimal drive-by conversions to struct intel_display in the callers while at it.

2024-11-07drm/i915/cdclk: Extract hsw_ips_min_cdclk()Ville Syrjälä
Pull the whole BDW IPS min CDCLK stuff into the IPS code so that all the details around IPS are contained in once place. Note that while - min_cdclk = DIV_ROUND_UP(min_cdclk * 100, 95); vs. + min_cdclk = max(DIV_ROUND_UP(crtc_state->pixel_rate * 100, 95), min_cdclk) may look different, they are in fact the same because min_cdclk==crtc_state->pixel_rate at this point in intel_crtc_compute_min_cdclk() on BDW.

2024-10-30drm/i915/ips: convert to struct intel_displayJani Nikula
struct intel_display will replace struct drm_i915_private as the main device pointer for display code. Switch HSW IPS code over to it.

2024-09-05drm/i915/display: include media/cec-notifier.h and linux/debugfs.h where neededJani Nikula
Use a forward declaration for struct cec_notifier instead of including media/cec-notifier.h in intel_display_types.h, and only include it where needed. Also realize that a lot of places depend on including linux/debugfs.h via intel_display_types.h -> media/cec-notifier.h -> media/cec.h, and include that too where needed. v2: hsw_ips.c also needs debugfs.h (kernel test robot) Reviewed-by: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240827104521.4151471-1-jani.nikula@intel.com

2022-05-20drm/i915/pcode: Extend pcode functions for multiple gt'sAshutosh Dixit
Each gt contains an independent instance of pcode. Extend pcode functions to interface with pcode on different gt's. To avoid creating dependency of display functionality on intel_gt, pcode function interfaces are exposed in terms of uncore rather than intel_gt. Callers have been converted to pass in the appropritate (i915 or intel_gt) uncore to the pcode functions. v2: Expose pcode functions in terms of uncore rather than gt (Jani/Rodrigo) v3: Retain previous function names to eliminate needless #defines (Rodrigo) v4: Move out i915_pcode_init() to a separate patch (Tvrtko) Remove duplicated drm_err/drm_dbg from intel_pcode_init() (Tvrtko) Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ashutosh Dixit <ashutosh.dixit@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Andi Shyti <andi.shyti@linux.intel.com> Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220519085732.1276255-2-tvrtko.ursulin@linux.intel.com [tursulin: fixup merge conflict]

2022-02-09drm/i915: Move the IPS code to its own fileVille Syrjälä
IPS is a pretty well isolated feature. Move the relevant code to a separate file from polluting intel_display.c. I stuck to the hsw_ips name since that's what the function were already using, and also to avoid confusion with the ILK "Intelligen Power Sharing"/intel_ips GPU turbo stuff. And let's also do the s/dev_priv/i915/ rename while touching most of the code.
