In MTL onwards, pcode locks the GV point based on the peak BW of a QGV point. So store the peak BW of all the QGV points. v2: use DIV_ROUND_CLOSEST() for the peakBW calculation Bspec: 64636 Signed-off-by:

From MTL onwwards, pcode locks the QGV point based on peak BW of the intended QGV point passed by the driver. So the peak BW calculation must match the value expected by the pcode. Update the calculations as per the Bspec. v2: use DIV_ROUND_* macro for the calculations (Ville) v3: Use only DIV_ROUN_CLOSEST and remove divisor / 2 again Bspec: 64636 Signed-off-by:

Prepare for re-enabling -Wunused-but-set-variable. The variable is indeed 'unused' as the name suggests, but we can't just drop it because i915_vma_unbind_unlocked() is annotated __must_check. Apparently the selftest does not really need to check the value. Signed-off-by:

If i915_driver_create() fails to create a valid 'i915' object, we should just disable the PCI device and return immediately without trying to call i915_probe_error() that relies on a valid i915 pointer. Fixes: 12e6f6dc ("drm/i915/display: Handle GMD_ID identification in display code") Reported-by:

Moving display-specific runtime info initialization into display/ makes the display code more self-contained and also makes it easier to call from the Xe driver. v2: - Drop unnecessary display/ prefix from #includes. (Jani) - Clear runtime info if fusing leaves no pipes remaining, the same as we do when fusing indicates the entire display controller is unavailable. (Jani) - Move adjustment of DRIVER_MODESET / DRIVER_ATOMIC after call to intel_display_device_info_runtime_init(); HAS_DISPLAY may have changed to false during the runtime init.

Apparently desktop gen3 parts don't support the 10bit gamma mode at all. Stop claiming otherwise. As is the case with pipe A on gen3 mobile parts, the PIPECONF gamma mode bit can be set but it has no effect on the output. PNV seems to be the only slight exception, but generally the desktop PNV variant looks more like a mobile part so this is not entirely surprising.

When intel_dp_init_connector fails, some power wells used in dp aux communication may not be completely disabled yet. This may result in a null pointer dereference when icl_aux_pw_to_phy() is called from icl_combo_phy_aux_power_well_disable() after the encoder and connector are already freed. Signed-off-by:

Convert the topology manager to use struct drm_edid, add drm_dp_mst_edid_read() that returns drm_edid, and rewrite the old drm_dp_mst_get_edid() to use it. Note that the old drm_get_edid() ended up calling drm_connector_update_edid_property(). This responsibility is now deferred to drivers, which all do it anyway after calling drm_dp_mst_edid_read() or drm_dp_mst_get_edid(). Reviewed-by:
