2018-08-28drm/i915: Free write_buf that we allocated with kzalloc.Rodrigo Vivi
We use kzalloc to allocate the write_buf that we use for i2c transfer on hdcp write. But it seems that we are forgetting to free the memory that is not needed after i2c transfer is completed.

2018-06-19drm/i915: Allow DBLSCAN user modes with eDP/LVDS/DSIVille Syrjälä
When encountering a connector with the scaling mode property both intel and modesetting ddxs sometimes add tons of DBLSCAN modes to the output's mode list. The idea presumably being that since the output will be going through the panel fitter anyway we can pretend to use any kind of mode. Sadly that means we can't reject user modes with the DBLSCAN flag until we know whether we're going to be using the panel's native mode or the user mode directly. Doing otherwise means X clients using xf86vidmode/xrandr will get a protocol error (and often self terminate as a result) when the kernel refuses to use the requested mode with the DBLSCAN flag. To undo the regression we'll move the DBLSCAN checks into the connector->mode_valid() and encoder->compute_config() hooks.

2018-06-14drm/i915/ddi: Check transcoder instead of port when setting HDMI infoframeImre Deak
The only requirement by BSpec for setting the HDMI infoframes is on DDI platforms to do that before enabling the HDMI transcoder function, see VIDEO_DIP_CTL bit 16. Accordingly check for the transcoder function disabled state instead of the port's disabled state on DDI platforms. This is needed by the next patch as it will set the infoframe during crtc disabling where the port is still enabled.

2018-05-17i915: content-type property for HDMI connectorStanislav Lisovskiy
Added encoding of drm content_type property from drm_connector_state within AVI infoframe in order to properly handle external HDMI TV content-type setting. This requires also manipulationg ITC bit, as stated in HDMI spec. v2: * Moved helper function which attaches content type property to the drm core, as was suggested. Removed redundant connector state initialization. v3: * Removed caps in drm_content_type_enum_list. After some discussion it turned out that HDMI Spec 1.4 was wrongly assuming that IT Content(itc) bit doesn't affect Content type states, however itc bit needs to be manupulated as well. In order to not expose additional property for itc, for sake of simplicity it was decided to bind those together in same "content type" property. v4: * Added it_content checking in intel_digital_connector_atomic_check. Fixed documentation for new content type enum. v5: * Moved patch revision's description to commit messages. v6: * Minor naming fix for the content type enumeration string. v7: * Fix parameter name for documentation and parameter alignment in order not to get warning. Added Content Type description to new HDMI connector properties section. v8: * Thrown away unneeded numbers from HDMI content-type property description. Switch to strings desription instead of plain definitions. v9: * Moved away hdmi specific content-type enum from drm_connector_state. Content type property should probably not be bound to any specific connector interface in drm_connector_state. Same probably should be done to hdmi_picture_aspect_ration enum which is also contained in drm_connector_state. Added special helper function to get derive hdmi specific relevant infoframe fields. v10: * Added usage description to HDMI properties kernel doc. v11: * Created centralized function for filling HDMI AVI infoframe, based on correspondent DRM property value.

2018-03-23drm/i915: Don't spew errors when resetting HDMI scrambling/bit clock ratio failsVille Syrjälä
When we're disabling the HDMI link we try to reset the scrambling and TMDS bit clock ratio back to the default values. This will fail if the sink has already been disconnected. Thus we should not print an error message when resetting the scrambling/TMDS bit clock ratio fail during disable.

2018-01-19drm/i915: Ignore TMDS clock limit for DP++ when EDID override is setAbdiel Janulgue
4K modes testing by using dummy EDID data has never been working properly on boxes with DP++ (dual-mode) adaptors. The reason for this is that those modes got pruned during hdmi mode validation. intel_hdmi_mode_valid returns CLOCK_HIGH because the pixel clock reported by the 4k mode is higher than dual port TMDS clock limit. However 4k injection does work properly on machines that don't have DP++ adapters because the mode is never validated against the DP++ TMDS clock limit. v2: Don't detect the DP++ limits when we're testing using overridden EDIDs. Make sure to check for the override condition after respecting the value of drm_dp_dual_mode_detect (Jani Nikula).

2018-01-09drm/i915: Try EDID bitbanging on HDMI after failed readStefan Brüns
The ACK/NACK implementation as found in e.g. the G965 has the falling clock edge and the release of the data line after the ACK for the received byte happen at the same time. This is conformant with the I2C specification, which allows a zero hold time, see footnote [3]: "A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the V IH(min) of the SCL signal) to bridge the undefined region of the falling edge of SCL." Some HDMI-to-VGA converters apparently fail to adhere to this requirement and latch SDA at the falling clock edge, so instead of an ACK sometimes a NACK is read and the slave (i.e. the EDID ROM) ends the transfer. The bitbanging releases the data line for the ACK only 1/4 bit time after the falling clock edge, so a slave will see the correct value no matter if it samples at the rising or the falling clock edge or in the center. Fallback to bitbanging is already done for the CRT connector.

2017-11-22drm/edid: Allow HDMI infoframe without VIC or S3DVille Syrjälä
Appedix F of HDMI 2.0 says that some HDMI sink may fail to switch from 3D to 2D mode in a timely fashion if the source simply stops sending the HDMI infoframe. The suggested workaround is to keep sending the infoframe even when strictly not necessary (ie. no VIC and no S3D). HDMI 1.4 does allow for this behaviour, stating that sending the infoframe is optional in this case. The infoframe was first specified in HDMI 1.4, so in theory sinks predating that may not appreciate us sending an uknown infoframe their way. To avoid regressions let's try to determine if the sink supports the infoframe or not. Unfortunately there's no direct way to do that, so instead we'll just check if we managed to parse any HDMI 1.4 4k or stereo modes from the EDID, and if so we assume the sink will accept the infoframe. Also if the EDID contains the HDMI 2.0 HDMI Forum VSDB we can assume the sink is prepared to receive the infoframe. v2: Fix getting has_hdmi_infoframe from display_info Always fail constructing the infoframe if the display possibly can't handle it Cc: Shashank Sharma <shashank.sharma@intel.com> Cc: Andrzej Hajda <a.hajda@samsung.com> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Shashank Sharma <shashank.sharma@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20171113170427.4150-3-ville.syrjala@linux.intel.com

2017-11-15drm/edid: Don't send non-zero YQ in AVI infoframe for HDMI 1.x sinksVille Syrjälä
Apparently some sinks look at the YQ bits even when receiving RGB, and they get somehow confused when they see a non-zero YQ value. So we can't just blindly follow CEA-861-F and set YQ to match the RGB range. Unfortunately there is no good way to tell whether the sink designer claims to have read CEA-861-F. The CEA extension block revision number has generally been stuck at 3 since forever, and even a very recently manufactured sink might be based on an old design so the manufacturing date doesn't seem like something we can use. In lieu of better information let's follow CEA-861-F only for HDMI 2.0 sinks, since HDMI 2.0 is based on CEA-861-F. For HDMI 1.x sinks we'll always set YQ=0. The alternative would of course be to always set YQ=0. And if we ever encounter a HDMI 2.0+ sink with this bug that's what we'll probably have to do.

2017-10-31drm/i915: Pass around crtc and connector states for audioVille Syrjälä
Explicitly pass the crtc and connector states into the audio code enable/disable hooks, and plumb them all the way down. This gets rid of almost all crtc->config and encoder->crtc uses. The one place where we still use them is i915_audio_component_sync_audio_rate() since that gets called from the audio driver and we don't have explicit states around then.

2017-10-30drm/i915: Stop frobbing with DDI encoder->typeVille Syrjälä
Currently the DDI encoder->type will change at runtime depending on what kind of hotplugs we've processed. That's quite bad since we can't really trust that that current value of encoder->type actually matches the type of signal we're trying to drive through it. Let's eliminate that problem by declaring that non-eDP DDI port will always have the encoder type as INTEL_OUTPUT_DDI. This means the code can no longer try to distinguish DP vs. HDMI based on encoder->type. We'll leave eDP as INTEL_OUTPUT_EDP, since it'll never change and there's a bunch of code that relies on that value to identify eDP encoders. We'll introduce a new encoder .compute_output_type() hook. This allows us to compute the full output_types before any encoder .compute_config() hooks get called, thus those hooks can rely on output_types being correct, which is useful for cloning on oldr platforms. For now we'll just look at the connector type and pick the correct mode based on that. In the future the new hook could be used to implement dynamic switching between LS and PCON modes for LSPCON. v2: Fix BXT/GLK PPS explosion with DSI/MST encoders v3: Avoid the PPS warn on pure HDMI/DVI DDI encoders by checking dp.output_reg v4: Rebase v5: Populate output_types in .get_config() rather than in the caller v5: Split out populating output_types in .get_config() (Maarten) Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20171027193128.14483-3-ville.syrjala@linux.intel.com Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

Rather than having the caller of .get_config() set output_types based on encoder->type, let's just have .get_config() itself populate output_types. This way we are isolated from encoder->type, which won't be useable for this purpose anyway soon (at least for DDI encoders).

2017-10-17drm/i915: Remove mostly duplicated video DIP handling from PSR codeVille Syrjälä
Now that the infoframe hooks are part of the intel_dig_port, we can use the normal .write_infoframe() hook to update the VSC SDP. We do need to deal with the size difference between the VSC DIP and the others though. Another minor snag is that the compiler will complain to use if we keep using enum hdmi_infoframe_type type and passing in the DP define instead, so et's just change to unsigned int all over for the inforframe type. v2: Rebase due to other PSR changes Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20171013194051.19286-1-ville.syrjala@linux.intel.com
