2024-04-15drm: prefer DRM_MODE_FMT/ARG over drm_mode_debug_printmodeline()Jani Nikula1-3/+3
We have DRM_MODE_FMT and DRM_MODE_ARG() macros to allow unified debug printing of modes in any printk-formatted logging. Prefer them over drm_mode_debug_printmodeline(). This allows drm device specific logging of modes, in the right drm debug category, and inline with the rest of the logging instead of split to multiple lines.

2023-11-24drm/atomic: Add support for mouse hotspotsZack Rusin1-0/+20
Atomic modesetting code lacked support for specifying mouse cursor hotspots. The legacy kms DRM_IOCTL_MODE_CURSOR2 had support for setting the hotspot but the functionality was not implemented in the new atomic paths. Due to the lack of hotspots in the atomic paths userspace compositors completely disable atomic modesetting for drivers that require it (i.e. all paravirtualized drivers). This change adds hotspot properties to the atomic codepaths throughtout the DRM core and will allow enabling atomic modesetting for virtualized drivers in the userspace.

If the driver supports it, allow user-space to supply the DRM_MODE_PAGE_FLIP_ASYNC flag to request an async page-flip. Set drm_crtc_state.async_flip accordingly. Document that drivers will reject atomic commits if an async flip isn't possible. This allows user-space to fall back to something else. For instance, Xorg falls back to a blit.

2022-11-24drm/connector: Add TV standard propertyMaxime Ripard1-0/+4
The TV mode property has been around for a while now to select and get the current TV mode output on an analog TV connector. Despite that property name being generic, its content isn't and has been driver-specific which makes it hard to build any generic behaviour on top of it, both in kernel and user-space. Let's create a new enum tv norm property, that can contain any of the analog TV standards currently supported by kernel drivers. Each driver can then pass in a bitmask of the modes it supports, and the property creation function will filter out the modes not supported. We'll then be able to phase out the older tv mode property.

2022-05-02drm: handle kernel fences in drm_gem_plane_helper_prepare_fb v2Christian König1-42/+5
drm_gem_plane_helper_prepare_fb() was using drm_atomic_set_fence_for_plane() which ignores all implicit fences when an explicit fence is already set. That's rather unfortunate when the fb still has a kernel fence we need to wait for to avoid presenting garbage on the screen. So instead update the fence in the plane state directly. While at it also take care of all potential GEM objects and not just the first one. Also remove the now unused drm_atomic_set_fence_for_plane() function, new drivers should probably use the atomic helpers directly. v2: improve kerneldoc, use local variable and num_planes, WARN_ON_ONCE on missing planes.

2022-03-31drm/atomic: Print the state every non-blocking commitMaxime Ripard1-4/+0
The DRM_UT_STATE controls whether we're calling drm_atomic_print_new_state() whenever a new state is committed. However, that call is made in the drm_mode_atomic_ioctl(), whereas we have multiple users of the drm_atomic_commit() function in the kernel (framebuffer emulation, drm_atomic_helper_dirtyfb, etc.). This leads to multiple states being committed but never actually displayed even though we asked to have verbose atomic state debugging. Let's move the call to drm_atomic_print_new_state() to drm_atomic_commit() to make sure we don't miss any. Non-blocking commits were never logged though, and it would create too much churn in the logs to do so, so leave them out for now.

Drivers can set up this property for a plane by calling drm_plane_create_scaling_filter() and for a CRTC by calling drm_crtc_create_scaling_filter(). NN filter works by filling in the missing color values in the upscaled image with that of the coordinate-mapped nearest source pixel value.

2019-08-06drm: Add Content protection type propertyRamalingam C1-0/+4
This patch adds a DRM ENUM property to the selected connectors. This property is used for mentioning the protected content's type from userspace to kernel HDCP authentication. Type of the stream is decided by the protected content providers. Type 0 content can be rendered on any HDCP protected display wires. But Type 1 content can be rendered only on HDCP2.2 protected paths. So when a userspace sets this property to Type 1 and starts the HDCP enable, kernel will honour it only if HDCP2.2 authentication is through for type 1. Else HDCP enable will be failed. Pekka have completed the Weston DRM-backend review in https://gitlab.freedesktop.org/wayland/weston/merge_requests/48 and the UAPI for HDCP 2.2 looks good.

2019-06-13drm: Add helpers to kick off self refresh mode in driversSean Paul1-2/+5
This patch adds a new drm helper library to help drivers implement self refresh. Drivers choosing to use it will register crtcs and will receive callbacks when it's time to enter or exit self refresh mode. In its current form, it has a timer which will trigger after a driver-specified amount of inactivity. When the timer triggers, the helpers will submit a new atomic commit to shut the refreshing pipe off. On the next atomic commit, the drm core will revert the self refresh state and bring everything back up to be actively driven. From the driver's perspective, this works like a regular disable/enable cycle. The driver need only check the 'self_refresh_active' state in crtc_state. It should initiate self refresh mode on the panel and enter an off or low-power state. Changes in v2: - s/psr/self_refresh/ (Daniel) - integrated the psr exit into the commit that wakes it up (Jose/Daniel) - made the psr state per-crtc (Jose/Daniel) Changes in v3: - Remove the self_refresh_(active|changed) from connector state (Daniel) - Simplify loop in drm_self_refresh_helper_alter_state (Daniel) - Improve self_refresh_aware comment (Daniel) - s/self_refresh_state/self_refresh_data/ (Daniel) Changes in v4: - Move docbook location below panel (Daniel) - Improve docbook with references and more detailed explanation (Daniel) - Instead of register/unregister, use init/cleanup (Daniel) Changes in v5: - Resolved conflict in drm_atomic_helper.c #include block - Resolved conflict in rst with HDCP helper docs Changes in v6: - Fix include ordering, clean up forward declarations (Sam) Link to v1: https://patchwork.freedesktop.org/patch/msgid/20190228210939.83386-2-sean@poorly.run Link to v2: https://patchwork.freedesktop.org/patch/msgid/20190326204509.96515-1-sean@poorly.run Link to v3: https://patchwork.freedesktop.org/patch/msgid/20190502194956.218441-6-sean@poorly.run Link to v4: https://patchwork.freedesktop.org/patch/msgid/20190508160920.144739-6-sean@poorly.run Link to v5: https://patchwork.freedesktop.org/patch/msgid/20190611160844.257498-6-sean@poorly.run Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Jose Souza <jose.souza@intel.com> Cc: Zain Wang <wzz@rock-chips.com> Cc: Tomasz Figa <tfiga@chromium.org> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Sam Ravnborg <sam@ravnborg.org> Tested-by: Heiko Stuebner <heiko@sntech.de> Reviewed-by: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190612145026.191846-1-sean@poorly.run

2019-03-18drm: writeback: Add job prepare and cleanup operationsLaurent Pinchart1-23/+8
As writeback jobs contain a framebuffer, drivers may need to prepare and cleanup them the same way they can prepare and cleanup framebuffers for planes. Add two new optional connector helper operations, .prepare_writeback_job() and .cleanup_writeback_job() to support this. The job prepare operation is called from drm_atomic_helper_prepare_planes() to avoid a new atomic commit helper that would need to be called by all drivers not using drm_atomic_helper_commit(). The job cleanup operation is called from the existing drm_writeback_cleanup_job() function, invoked both when destroying the job as part of a aborted commit, or when the job completes. The drm_writeback_job structure is extended with a priv field to let drivers store per-job data, such as mappings related to the writeback framebuffer. For internal plumbing reasons the drm_writeback_job structure needs to store a back-pointer to the drm_writeback_connector. To avoid pushing too much writeback-specific knowledge to drm_atomic_uapi.c, create a drm_writeback_set_fb() function, move the writeback job setup code there, and set the connector backpointer. The prepare_signaling() function doesn't need to allocate writeback jobs and can ignore connectors without a job, as it is called after the writeback jobs are allocated to store framebuffers, and a writeback fence with a framebuffer is an invalid configuration that gets rejected by the commit check.
