Since i915's display code will soon be shared by two DRM drivers (i915 and Xe), it makes sense for the display code itself to be responsible for recognizing the platform it's running on rather than relying on the making the top-level DRM driver handle this. This also becomes more important for all platforms MTL and beyond where we're not really supposed to identify platform behavior by PCI device ID anymore, but rather by the hardware IP version reported by the device through the GMD_ID register. This series creates a more well-defined split between display and non-display deviceinfo/runtimeinfo and then moves the definition of the display-specific feature flags under the display/ code. Finally, it switches MTL (and all future platforms), to select the display feature flags based on the hardware's GMD_ID identification. v2: - Move DISPLAY_INFO() definition one patch earlier. (Andrzej) - Rename display's runtime default structure to __runtime_defaults to make it more clear what the purpose is. (Andrzej) - Simplify copy of runtime defaults to per-device runtime data. (Andrzej) - Fix uninitialized ptr use on error path during device probe. (lkp) - Add extra patch moving display-specific feature test macros to display/intel_display_device.h Cc: Jani Nikula <jani.nikula@xxxxxxxxx> Cc: Lucas De Marchi <lucas.demarchi@xxxxxxxxx> Cc: Andrzej Hajda <andrzej.hajda@xxxxxxxxx> Matt Roper (5): drm/i915/display: Move display device info to header under display/ drm/i915: Convert INTEL_INFO()->display to a pointer drm/i915/display: Move display runtime info to display structure drm/i915/display: Make display responsible for probing its own IP drm/i915/display: Handle GMD_ID identification in display code drm/i915/display: Move feature test macros to intel_display_device.h drivers/gpu/drm/i915/Makefile | 2 + drivers/gpu/drm/i915/display/intel_color.c | 31 +- drivers/gpu/drm/i915/display/intel_crtc.c | 2 +- drivers/gpu/drm/i915/display/intel_cursor.c | 4 +- drivers/gpu/drm/i915/display/intel_display.c | 2 +- drivers/gpu/drm/i915/display/intel_display.h | 10 +- .../drm/i915/display/intel_display_device.c | 764 ++++++++++++++++++ .../drm/i915/display/intel_display_device.h | 129 +++ .../drm/i915/display/intel_display_power.c | 6 +- .../drm/i915/display/intel_display_reg_defs.h | 14 +- drivers/gpu/drm/i915/display/intel_fb_pin.c | 2 +- drivers/gpu/drm/i915/display/intel_fbc.c | 6 +- drivers/gpu/drm/i915/display/intel_hdcp.c | 2 +- drivers/gpu/drm/i915/display/intel_hti.c | 2 +- .../drm/i915/display/skl_universal_plane.c | 2 +- drivers/gpu/drm/i915/display/skl_watermark.c | 8 +- drivers/gpu/drm/i915/i915_driver.c | 17 +- drivers/gpu/drm/i915/i915_drv.h | 65 +- drivers/gpu/drm/i915/i915_pci.c | 382 +-------- drivers/gpu/drm/i915/i915_reg.h | 33 - drivers/gpu/drm/i915/intel_device_info.c | 113 +-- drivers/gpu/drm/i915/intel_device_info.h | 67 +- drivers/gpu/drm/i915/intel_step.c | 8 +- 23 files changed, 1030 insertions(+), 641 deletions(-) create mode 100644 drivers/gpu/drm/i915/display/intel_display_device.c create mode 100644 drivers/gpu/drm/i915/display/intel_display_device.h -- 2.40.0
