2019-03-18drm: Clarify definition of the DRM_BUS_FLAG_(PIXDATA|SYNC)_* macrosLaurent Pinchart
The DRM_BUS_FLAG_PIXDATA_POSEDGE and DRM_BUS_FLAG_PIXDATA_NEGEDGE macros and their DRM_BUS_FLAG_SYNC_* counterparts define on which pixel clock edge data and sync signals are driven. They are however used in some drivers to define on which pixel clock edge data and sync signals are sampled, which should usually (but not always) be the opposite edge of the driving edge. This creates confusion. Create four new macros for both PIXDATA and SYNC that explicitly state the driving and sampling edge in their name to remove the confusion. The driving macros are defined as the opposite of the sampling macros to made code simpler based on the assumption that the driving and sampling edges are opposite.

2019-02-19drm: Add HDMI colorspace propertyUma Shankar
Create a new connector property to program colorspace to sink devices. Modern sink devices support more than 1 type of colorspace like 601, 709, BT2020 etc. This helps to switch based on content type which is to be displayed. The decision lies with compositors as to in which scenarios, a particular colorspace will be picked. This will be helpful mostly to switch to higher gamut colorspaces like BT2020 when the media content is encoded as BT2020. Thereby giving a good visual experience to users. The expectation from userspace is that it should parse the EDID and get supported colorspaces. Use this property and switch to the one supported. Sink supported colorspaces should be retrieved by userspace from EDID and driver will not explicitly expose them. Basically the expectation from userspace is: - Set up CRTC DEGAMMA/CTM/GAMMA to convert to some sink colorspace - Set this new property to let the sink know what it converted the CRTC output to. v2: Addressed Maarten and Ville's review comments. Enhanced the colorspace enum to incorporate both HDMI and DP supported colorspaces. Also, added a default option for colorspace. v3: Removed Adobe references from enum definitions as per Ville, Hans Verkuil and Jonas Karlman suggestions. Changed Default to an unset state where driver will assign the colorspace is not chosen by user, suggested by Ville and Maarten. Addressed other misc review comments from Maarten. Split the changes to have separate colorspace property for DP and HDMI. v4: Addressed Chris and Ville's review comments, and created a common colorspace property for DP and HDMI, filtered the list based on the colorspaces supported by the respective protocol standard. v5: Made the property creation helper accept enum list based on platform capabilties as suggested by Shashank. Consolidated HDMI and DP property creation in the common helper. v6: Addressed Shashank's review comments. v7: Added defines instead of enum in uapi as per Brian Starkey's suggestion in order to go with string matching at userspace. Updated the commit message to add more details as well kernel docs. v8: Addressed Maarten's review comments. v9: Removed macro defines from uapi as per Brian Starkey and Daniel Stone's comments and moved to drm include file. Moved back to older design with exposing all HDMI colorspaces to userspace since infoframe capability is there even on legacy platforms, as per Ville's review comments. v10: Fixed sparse warnings, updated the RB from Maarten and Jani's ack. v11: Addressed Ville's review comments. Updated the Macro naming and added DCI-P3 colorspace as well, defined in CTA 861.G spec. v12: Appended BT709 and SMPTE 170M with YCC information as per Ville's review comment to be clear and not to be confused with RGB. v13: Reorder the colorspace macros. v14: Removed DP as of now, will be added later once full support is enabled, as per Ville's suggestion. Added Ville's RB.

Modern display hardware is capable of supporting variable refresh rates. This patch introduces the "vrr_capable" property on the connector to allow userspace to query support for variable refresh rates. Atomic drivers should attach this property to connectors that are capable of driving variable refresh rates using drm_connector_attach_vrr_capable_property(). The value should be updated based on driver and hardware capability by using drm_connector_set_vrr_capable_property().

2018-11-02drm: Add connector property to limit max bpcRadhakrishna Sripada
At times 12bpc HDMI cannot be driven due to faulty cables, dongles level shifters etc. To workaround them we may need to drive the output at a lower bpc. Currently the user space does not have a way to limit the bpc. The default bpc to be programmed is decided by the driver and is run against connector limitations. Creating a new connector property "max bpc" in order to limit the bpc. xrandr can make use of this connector property to make sure that bpc does not exceed the configured value. This property can be used by userspace to set the bpc.

2018-10-19drm/atomic_helper: Stop modesets on unregistered connectors harderLyude Paul
Unfortunately, it appears our fix in: commit b5d29843d8ef ("drm/atomic_helper: Allow DPMS On<->Off changes for unregistered connectors") Which attempted to work around the problems introduced by: commit 4d80273976bf ("drm/atomic_helper: Disallow new modesets on unregistered connectors") Is still not the right solution, as modesets can still be triggered outside of drm_atomic_set_crtc_for_connector(). So in order to fix this, while still being careful that we don't break modesets that a driver may perform before being registered with userspace, we replace connector->registered with a tristate member, connector->registration_state. This allows us to keep track of whether or not a connector is still initializing and hasn't been exposed to userspace, is currently registered and exposed to userspace, or has been legitimately removed from the system after having once been present. Using this info, we can prevent userspace from performing new modesets on unregistered connectors while still allowing the driver to perform modesets on unregistered connectors before the driver has finished being registered. Changes since v1: - Fix WARN_ON() in drm_connector_cleanup() that CI caught with this patchset in igt@drv_module_reload@basic-reload-inject and igt@drv_module_reload@basic-reload by checking if the connector is registered instead of unregistered, as calling drm_connector_cleanup() on a connector that hasn't been registered with userspace yet should stay valid. - Remove unregistered_connector_check(), and just go back to what we were doing before in commit 4d80273976bf ("drm/atomic_helper: Disallow new modesets on unregistered connectors") except replacing READ_ONCE(connector->registered) with drm_connector_is_unregistered().

2018-06-20drm: Add writeback connector typeBrian Starkey
Writeback connectors represent writeback engines which can write the CRTC output to a memory framebuffer. Add a writeback connector type and related support functions. Drivers should initialize a writeback connector with drm_writeback_connector_init() which takes care of setting up all the writeback-specific details on top of the normal functionality of drm_connector_init(). Writeback connectors have a WRITEBACK_FB_ID property, used to set the output framebuffer, and a WRITEBACK_PIXEL_FORMATS blob used to expose the supported writeback formats to userspace. When a framebuffer is attached to a writeback connector with the WRITEBACK_FB_ID property, it is used only once (for the commit in which it was included), and userspace can never read back the value of WRITEBACK_FB_ID. WRITEBACK_FB_ID can only be set if the connector is attached to a CRTC. Changes since v1: - Added drm_writeback.c + documentation - Added helper to initialize writeback connector in one go - Added core checks - Squashed into a single commit - Dropped the client cap - Writeback framebuffers are no longer persistent Changes since v2: Daniel Vetter: - Subclass drm_connector to drm_writeback_connector - Relax check to allow CRTC to be set without an FB - Add some writeback_ prefixes - Drop PIXEL_FORMATS_SIZE property, as it was unnecessary Gustavo Padovan: - Add drm_writeback_job to handle writeback signalling centrally Changes since v3: - Rebased - Rename PIXEL_FORMATS -> WRITEBACK_PIXEL_FORMATS Chances since v4: - Embed a drm_encoder inside the drm_writeback_connector to reduce the amount of boilerplate code required from the drivers that are using it.

This patch adds a new optional connector property to allow userspace to enable protection over the content it is displaying. This will typically be implemented by the driver using HDCP. The property is a tri-state with the following values: - OFF: Self explanatory, no content protection - DESIRED: Userspace requests that the driver enable protection - ENABLED: Once the driver has authenticated the link, it sets this value The driver is responsible for downgrading ENABLED to DESIRED if the link becomes unprotected. The driver should also maintain the desiredness of protection across hotplug/dpms/suspend. If this looks familiar, I posted [1] this 3 years ago. We have been using this in ChromeOS across exynos, mediatek, and rockchip over that time.

This worked, except for a small fumble in the implementation: When we actually race with a concurrent connector unplug event, and our temporary connector reference turns out to be the final one, then everything breaks: We call the connector release function from whatever context we happen to be in, which can be an irq/atomic context. And connector freeing grabs all kinds of locks and stuff. Fix this by creating a specially safe put function for connetor_iter, which (in this rare case) punts the cleanup to a worker.

2017-12-04drm: Add support for a panel-orientation connector property, v6Hans de Goede
On some devices the LCD panel is mounted in the casing in such a way that the up/top side of the panel does not match with the top side of the device (e.g. it is mounted upside-down). This commit adds the necessary infra for lcd-panel drm_connector-s to have a "panel orientation" property to communicate how the panel is orientated vs the casing. Userspace can use this property to check for non-normal orientation and then adjust the displayed image accordingly by rotating it to compensate. Changes in v2: -Store panel_orientation in drm_display_info, so that drm_fb_helper.c can access it easily -Have a single drm_connector_init_panel_orientation_property rather then create and attach functions. The caller is expected to set drm_display_info.panel_orientation before calling this, then this will check for platform specific quirks overriding the panel_orientation and if the panel_orientation is set after this then it will attach the property.

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
