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.

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. In the unlikely event that this issue occurs, fix it by testing the return value of drm_dp_dsc_sink_max_slice_count() against zero.

Ville Syrjälä authored
Define and use the bitmasks for the x/y components of the skl+ scaler window pos/size registers. We stick to the full 16 bits mask here even though the hardware limits are actually lower. The current (ADL) hardware maximums are in fact: 14 bits for X size, 13 bits for X pos, 13 bits for Y size/pos. Yes, that is correct, X pos has less bits than the X size for some reason. But that doesn't actually matter for now as we don't currently even support such wide displays without the use of bigjoiner (due to max plane width limit). v2: Switch back to full 16bit masks since that's what we use transcoder timign regs and PIPESRC as well Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: -

Define and use the bitmasks for the x/y components of the ilk+ panel filter window pos/size registers. Note that we stick to the full 16 bit mask even though the actual hardware limits are lower (and somewhat platform dependent). BDW is actually limited to 13 bits horizontal and 12 bits vertical, with the high bits being hardwired to zero. HSW should have the same limits as BDW. And pre-HSW should be limited to 12bits in both directions as that's already the limit of the transcoder timing registers. Curiously on HSW and earlier platforms all 16 bits can actually be set, but presumably the hardware ignores the high bits. v2: Switch back to full 16bit masks since that's what we use transcoder timign regs and PIPESRC as well Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by:

The intel_dsi_msleep() helper skips sleeping if the MIPI-sequences have a version of 3 or newer and the panel is in vid-mode. This is based on the big comment around line 730 which starts with "Panel enable/disable sequences from the VBT spec.", where the "v3 video mode seq" column does not have any wait t# entries. Checking the Windows driver shows that it does always honor the VBT delays independent of the version of the VBT sequences. Commit 6fdb335f ("drm/i915/dsi: Use unconditional msleep for the panel_on_delay when there is no reset-deassert MIPI-sequence") switched to a direct msleep() instead of intel_dsi_msleep() when there is no MIPI_SEQ_DEASSERT_RESET sequence, to fix the panel on an Acer Aspire Switch 10 E SW3-016 not turning on. And now testing on a Nextbook Ares 8A shows that panel_on_delay must always be honored otherwise the panel will not turn on. Instead of only always using regular msleep() for panel_on_delay do as Windows does and always use regular msleep() everywhere were intel_dsi_msleep() is used and drop the intel_dsi_msleep() helper.

On ADLP+ Bspec allows DC5/6 to be enabled while power well 2 is enabled. Since the AUX and DDI power wells (except for port A/B) are also backed by power well 2, this would suggest that DC5/6 can be enabled while any of these AUX or DDI port functionalities are used. As opposed to this AUX transfers will time out on ADLP TypeC ports while DC6 is enabled. Until the restriction for DC5/6 is clarified in Bspec let's assume that the intention is to allow for using these power states while pipe A/B is enabled, but only for combo ports which can be used with eDP outputs. Similarly assume that AUX transaction initiated by the driver on any port requires DC states to be disabled.
