2019-02-12drm: content-type property for HDMI connectorStanislav Lisovskiy
Added content_type property to drm_connector_state in order to properly handle external HDMI TV content-type setting. 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.

According to ANSI-CTA-861-G specification: * EOTF is 8 bit, not 16; * metadata type is 8 bit, not 16; * There's no "Minimum Content Light Level" This patch will change the HDR metadata structures to reflect that. Also, this will fix problems seen on some TVs that were rejecting HDR metadata because it's size was too big (more than 26 bytes).

2018-03-19drm/edid: set ELD connector type in drm_edid_to_eld()Jani Nikula
[ Upstream commit 1d1c36650752b7fb81cee515a9bba4131cac4b7c ] Since drm_edid_to_eld() knows the connector type, we can set the type in ELD while at it. Most connectors this gets called on are not DP encoders, and with the HDMI type being 0, this does not change behaviour for non-DP. For i915 having this in place earlier would have saved a considerable amount of debugging that lead to the fix 2d8f63297b9f ("drm/i915: always update ELD connector type after get modes"). I don't see other drivers, even the ones calling drm_edid_to_eld() on DP connectors, setting the connector type in ELD.

2017-12-05drm/edid: Don't send non-zero YQ in AVI infoframe for HDMI 1.x sinksVille Syrjälä
commit 9271c0ca573e02a360b636ecd8cb408852f4e9f6 upstream. 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.

2017-07-14drm/edid: parse YCBCR420 videomodes from EDIDShashank Sharma
HDMI 2.0 spec adds support for YCBCR420 sub-sampled output. CEA-861-F adds two new blocks in EDID's CEA extension blocks, to provide information about sink's YCBCR420 output capabilities. These blocks are: - YCBCR420vdb(YCBCR 420 video data block): This block contains VICs of video modes, which can be sopported only in YCBCR420 output mode (Not in RGB/YCBCR444/422. Its like a normal SVD block, valid for YCBCR420 modes only. - YCBCR420cmdb(YCBCR 420 capability map data block): This block gives information about video modes which can support YCBCR420 output mode also (along with RGB,YCBCR444/422 etc) This block contains a bitmap index of normal svd videomodes, which can support YCBCR420 output too. So if bit 0 from first vcb byte is set, first video mode in the svd list can support YCBCR420 output too. Bit 1 means second video mode from svd list can support YCBCR420 output too, and so on. This patch adds two bitmaps in display's hdmi_info structure, one each for VCB and VDB modes. If the source is HDMI 2.0 capable, this patch adds: - VDB modes (YCBCR 420 only modes) in connector's mode list, also makes an entry in the vdb_bitmap per vic. - VCB modes (YCBCR 420 also modes) only entry in the vcb_bitmap. Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Cc: Jose Abreu <joabreu@synopsys.com> Cc: Emil Velikov <emil.l.velikov@gmail.com> V2: Addressed Review comments from Emil: - Use 1ULL<<i instead of 1<<i to make sure the output is 64bit. - Use the suggested method for updating dbmap. - Add documentation for YCBCR420_vcb_map to fix kbuild warning. Review comments from Ville: - Do not expose the YCBCR420 flags in uabi layer, keep it internal. - Save a map of YCBCR420 modes for future reference. - Check db length before trying to parse extended tag. - Add a warning if there are > 64 modes in capability map block. - Use y420cmdb in function names and macros while dealing with vcb to be aligned with spec. - Move the display information parsing block ahead of mode parsing blocks. V3: Addressed design/review comments from Ville - Do not add flags in video modes, else we have to expose them to user - There should not be a UABI change, and kernel should detect the choice of the output based on type of mode, and the bitmaps. - Use standard bitops from kernel bitmap header, instead of calculating bit positions manually.

2017-07-14drm: handle HDMI 2.0 VICs in AVI info-framesShashank Sharma
HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64). For any other mode, the VIC filed in AVI infoframes should be 0. HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is extended to (VIC 1-107). This patch adds a bool input variable, which indicates if the connected sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a HDMI 2.0 VIC to a HDMI 1.4 sink. This patch touches all drm drivers, who are callers of this function drm_hdmi_avi_infoframe_from_display_mode but to make sure there is no change in current behavior, is_hdmi2 is kept as false. In case of I915 driver, this patch: - checks if the connected display is HDMI 2.0. - HDMI infoframes carry one of this two type of information: - VIC for 4K modes for HDMI 1.4 sinks - S3D information for S3D modes As CEA-861-F has already defined VICs for 4K videomodes, this patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks, until the mode is 3D.

2017-03-21drm/edid: detect SCDC support in HF-VSDBShashank Sharma
This patch does following: - Adds a new structure (drm_hdmi_info) in drm_display_info. This structure will be used to save and indicate if sink supports advanced HDMI 2.0 features - Adds another structure drm_scdc within drm_hdmi_info, to reflect scdc support and capabilities in connected HDMI 2.0 sink. - Checks the HF-VSDB block for presence of SCDC, and marks it in scdc structure - If SCDC is present, checks if sink is capable of generating SCDC read request, and marks it in scdc structure. V2: Addressed review comments Thierry: - Fix typos in commit message and make abbreviation consistent across the commit message. - Change structure object name from hdmi_info -> hdmi - Fix typos and abbreviations in description of structure drm_hdmi_info end the description with a full stop. - Create a structure drm_scdc, and keep all information related to SCDC register set (supported, read request supported) etc in it. Ville: - Change rr -> read_request - Call drm_detect_scrambling function drm_parse_hf_vsdb so that all of HF-VSDB parsing can be kept in same function, in incremental patches. V3: Rebase. V4: Rebase. V5: Rebase. V6: Addressed review comments from Ville - Add clock rate calculations for 1/10 and 1/40 ratios - Remove leftovers from old patchset V7: Added R-B from Jose. V8: Rebase. V9: Rebase. V10: Rebase.

2017-03-06drm/edid: Add EDID_QUIRK_FORCE_8BPC quirk for Rotel RSX-1058Tomeu Vizoso
Rotel RSX-1058 is a receiver with 4 HDMI inputs and a HDMI output, all 1.1. When a sink that supports deep color is connected to the output, the receiver will send EDIDs that advertise this capability, even if it isn't possible with HDMI versions earlier than 1.3. Currently the kernel is assuming that deep color is possible and the sink displays an error. This quirk will make sure that deep color isn't used with this particular receiver.

2017-01-26drm/edid: Set YQ bits in the AVI infoframe according to CEA-861-FVille Syrjälä
CEA-861-F tells us: "When transmitting any RGB colorimetry, the Source should set the YQ-field to match the RGB Quantization Range being transmitted (e.g., when Limited Range RGB, set YQ=0 or when Full Range RGB, set YQ=1) and the Sink shall ignore the YQ-field." So let's go ahead and do that. Perhaps there are sinks that don't ignore the YQ as they should for RGB? I wasn't able to find similar text in CEA-861-E, so it would seem to be a fairly "recent" addition.

2017-01-26drm/edid: Set AVI infoframe Q even when QS=0Ville Syrjälä
HDMI 2.0 recommends that we set the Q bits in the AVI infoframe even when the sink does not support quantization range selection (QS=0). According to CEA-861 we can do that as long as the Q we send matches the default quantization range for the mode. Previously I think I had misread the spec as saying that you can't send a non-zero Q at all when QS=0.

<drm/drm_crtc.h> used to define most of the in-kernel KMS API. It has now been split into separate files for each object type, but still includes most other KMS headers to avoid breaking driver compilation. As a step towards fixing that problem, remove the inclusion of <drm/drm_encoder.h> from <drm/drm_crtc.h> and include it instead where appropriate. Also remove the forward declarations of the drm_encoder and drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not needed in the header. <drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a forward declaration of struct drm_encoder in order to allow including it as the first header in a compilation unit.

2016-11-28drm/edid: Consider alternate cea timings to be the same VICVille Syrjälä
CEA-861 specifies that the vertical front porch may vary by one or two lines for specific VICs. Up to now we've only considered a mode to match the VIC if it matched the shortest possible vertical front porch length (as that is the variant we store in cea_modes[]). Let's allow our VIC matching to work with the other timings variants as well so that that we'll send out the correct VIC if the variant actually used isn't the one with the shortest vertical front porch.

2016-10-25drm/edid: Only print the bad edid when abortingChris Wilson
Currently, if drm.debug is enabled, we get a DRM_ERROR message on the intermediate edid reads. This causes transient failures in CI which flags up the sporadic EDID read failures, which are recovered by rereading the EDID automatically. This patch combines the reporting done by drm_do_get_edid() itself with the bad block printing from get_edid_block(), into a single warning associated with the connector once all attempts to retrieve the EDID fail. v2: Print the whole EDID, marking up the bad/zero blocks. This requires recording the whole of the raw edid, then a second pass to reduce it to the valid extensions. v3: Fix invalid/valid extension fumble.
