During HW state readout/sanitization an up-to-date connector atomic state will be required by a follow-up patch, which can disable CRTCs with an encoder (and calling the correct encoder hooks happens via the connector atomic state encoder pointer). So update the connector state already before the CRTC sanitize/disable step. For now this doesn't make a difference, since intel_modeset_update_connector_atomic_state() will update/enable the atomic state only for connectors that have an enabled encoder/CRTC. Such CRTCs/encoders will not be affected by intel_sanitize_crtc(). v2: Add comment about why the connector state needs to be up-to-date. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

Make sure that the CRTC state is reset correctly, as expected after disabling the CRTC. In particular this change will: - Zero all the CSC blob pointers after intel_crtc_free_hw_state() has freed them. - Zero the shared DPLL and port PLL pointers and clear the corresponding CRTC reference flag in the PLL state. - Reset all the transcoder and pipe fields. v2: - Reset fully the CRTC state. (Ville) - Clear pipe active flags in the DPLL state. v3: - Clear only the CRTC reference flag and add a helper for this. (Ville) v4: - Rebased on previous patch, adding intel_unreference_shared_dpll_crtc() separately. (Ville) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

For a bigjoiner configuration display->crtc_disable() will be called first for the slave CRTCs and then for the master CRTC. However slave CRTCs will be actually disabled only after the master CRTC is disabled (from the encoder disable hooks called with the master CRTC state). Hence the slave PIPEDMCs can be disabled only after the master CRTC is disabled, make this so. intel_encoders_post_pll_disable() must be called only for the master CRTC, as for the other two encoder disable hooks. While at it fix this up as well. This didn't cause a problem, since intel_encoders_post_pll_disable() will call the corresponding hook only for an encoder/connector connected to the given CRTC, however slave CRTCs will have no associated encoder/connector.

Since topology state is being added to drm_atomic_state now all drm_modeset_lock required are being taken from core. This raises an issue when we try to loop over connector and assign vcpi id to our streams as we did not have atomic state to derive acquire_ctx from. We fill in stream info if dpmst encoder is found before enabling hdcp. intel_hdcp_required_stream will be broken which will only set the content type. --v2 -move prepare streams to beginning of intel_hdcp_enable to avoid checking of mst encoder twice [Ankit] --v3 -break intel_required_content_stream to two part and set the stream_id at the beginning [Ankit] --v4 -change return types for intel_hdcp_prepare_stream and intel_hdcp_required content_stream [Ankit] -rename intel_hdcp_set_content_stream to intel_hdcp_set_stream [Ankit] -place intel_hdcp_set_streams above caller [Ankit] Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Signed-off-by:

Swap the roles of the index vs. value for the VBT DDC pin mapping tables. This is not strictly necessary for DDC pins but it will make this work exactly like the AUX CH mapping tables where the role reversal is necessary (or at least makes things easier). Consistency is good. Signed-off-by:

The big switch+if statement mess in map_aux_ch() is illegible. Split up into cleaner per-platform arrays like we already have for the gmbus pins. We use enum aux_ch as the index and the VBT thing as the value. Slightly non-intuitive perhaps but if we did it the other way around we'd have problems with AUX_CH_A being zero, and thus any non-populated element would look like AUX_CH_A. v2: flip the index vs. value around TODO: Didn't bother with the platform variants beyond the ones that really need remapping, which means if the VBT is bogus we end up with a nonexistent aux ch. Might be nice to check this a bit better. Yet another bitmask in device info? Signed-off-by: -

For development and testing purposes, the i915.force_probe module parameter and DRM_I915_FORCE_PROBE kconfig option allow probing of devices that aren't supported by the driver. The i915.force_probe module parameter is "unsafe" and setting it taints the kernel. However, using the kconfig option does not. Always taint the kernel when force probing a device that is not supported. v2: Drop "depends on EXPERT" to avoid build breakage (kernel test robot) Fixes: 7ef5ef5c ("drm/i915: add force_probe module parameter to replace alpha_support") Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Dave Airlie <airlied@gmail.com> Acked-by:

On g4x the hardware has only one audio/video DIP block. Thus only one HDMI port can transmit audio/infoframes at a time. Currently we pretend that multiple ports can do it at the same time, but that doesn't actually work for two reasons: - the state of the single hw block will get clobbered by the multiple ports, leading to state checker failures - the hardware will automagically disable audio/infoframe transmission when enabled on multiple ports To fix this let's allow only one of the ports to transmit audio/infoframes at a time. We'll just go over all the HDMI ports and pick the first one that is otherwise capable of audio/infoframes. Further HDMI ports will be treated as if they had a DVI sink connected. In order to compute this consistently we'll also need to always add all HDMI ports to the atomic state. Signed-off-by:

The decision to use DFP output format conversion capabilities should be during compute_config phase. This patch uses the members of intel_dp->dfp to only store the format conversion capabilities of the DP device and uses the crtc_state sink_format member, to program the protocol-converter for colorspace/format conversion. v2: Use sink_format to determine the color conversion config for the pcon (Ville). v3: Fix typo: missing 'break' in switch case (lkp kernel test robot). v4: Add helper to check if DP supports YCBCR420. v5: Simplify logic for computing output_format, based on the given sink_format.

Added scaler constraint for YCbCr420 output. v6: Split the patch for Scaler constraint for Ycbcr420. v7: Simplify the policy for selecting output_format: Always try for RGB first, followed by YCBCR444, and finally by YCBCR420. v8: Removed redundant comments, minor refactoring.

The decision to use DFP output format conversion capabilities should be during compute_config phase. This patch adds new member to crtc_state to represent the final output_format to the sink. In case of a DFP this can be different than the output_format, as per the format conversion done via the PCON. This will help to store only the format conversion capabilities of the DP device in intel_dp->dfp, and use crtc_state to compute and store the configuration for color/format conversion for a given mode. v2: modified the new member to crtc_state to represent the final output_format that eaches the sink, after possible conversion by PCON kind of devices. (Ville) v3: Addressed comments from Ville: -Added comments to clarify difference between sink_format and output_format. -Corrected the order of setting sink_format and output_format. -Added readout for sink_format in get_pipe_config hooks. v4: Set sink_format for intel_sdvo too.

drm_dp_dsc_sink_max_slice_count() may return 0 if something goes wrong on the part of the DSC sink and its DPCD register. This null value may be later used as a divisor in intel_dsc_compute_params(), which will lead to an error.
