Use the new cec_notifier_conn_(un)register() functions to (un)register the notifier for the HDMI connector, and fill in the cec_connector_info. Changes since v7: - err_runtime_disable -> err_rpm_disable Changes since v2: - removed unnecessary call to invalidate phys address before deregistering the notifier, - use cec_notifier_phys_addr_invalidate instead of setting invalid address on a notifier.

The implementation of functions encoder_enable and encoder_disable make possible to control the pinctrl according to the encoder type. The pinctrl must be activated only if the encoder type is DPI. This helps to move the DPI-related pinctrl configuration from all the panel or bridge to the LTDC dt node.

The drm panel bridge creates a connector using a connector type explicitly passed by the display controller or bridge driver that instantiates the panel bridge. Now that drm_panel reports its connector type, we can use it to avoid passing an explicit (and often incorrect) connector type to drm_panel_bridge_add() and devm_drm_panel_bridge_add(). Several drivers report incorrect or unknown connector types to userspace. Reporting a different type may result in a breakage. For that reason, rename (devm_)drm_panel_bridge_add() to (devm_)drm_panel_bridge_add_typed(), and add new (devm_)drm_panel_bridge_add() functions that use the panel connector type. Update all callers of (devm_)drm_panel_bridge_add() to the _typed function, they will be converted one by one after testing. The panel drivers have been updated with the following Coccinelle semantic patch, with manual inspection and fixes to indentation. @@ expression bridge; expression dev; expression panel; identifier type; @@ ( -bridge = drm_panel_bridge_add(panel, type); +bridge = drm_panel_bridge_add_typed(panel, type); | -bridge = devm_drm_panel_bridge_add(dev, panel, type); +bridge = devm_drm_panel_bridge_add_typed(dev, panel, type); ) Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Boris Brezillon <boris.brezillon@collabora.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190904132804.29680-3-laurent.pinchart@ideasonboard.com

Add a type field to the drm_panel structure to report the panel type, using DRM_MODE_CONNECTOR_* macros (the values that make sense are LVDS, eDP, DSI and DPI). This will be used to initialise the corresponding connector type. Update all panel drivers accordingly. The panel-simple driver only specifies the type for the known to be LVDS panels, while all other panels are left as unknown and will be converted on a case-by-case basis as they all need to be carefully reviewed.

- it's what we recommend in our docs: https://dri.freedesktop.org/docs/drm/gpu/drm-uapi.html#recommended-ioctl-return-values - it's the overwhelmingly used error code for "operation not supported", at least in drm core (slightly less so in drivers): $ git grep EOPNOTSUPP -- drivers/gpu/drm/*c | wc -l 83 $ git grep ENOTSUPP -- drivers/gpu/drm/*c | wc -l 5 - include/linux/errno.h makes it fairly clear that these are for nfsv3 (plus they also have error codes above 512, which is the block with some special behaviour ...) /* Defined for the NFSv3 protocol */ If the above isn't reflecting current practice, then I guess we should at least update the docs. Noralf commented: Ben Hutchings made this comment[1] in a thread about use of ENOTSUPP in drivers: glibc's strerror() returns these strings for ENOTSUPP and EOPNOTSUPP respectively: "Unknown error 524" "Operation not supported" So at least for errors returned to userspace EOPNOTSUPP makes sense. José asked: > Hopefully this will not break any userspace None of the functions in drm_edid.c affected by this reach userspace, it's all driver internal. Same for the mipi function, that error code should be handled by drivers. Drivers are supposed to remap "the hw is on fire" to EIO when reporting up to userspace, but I think if a driver sees this it would be a driver bug. v2: Augment commit message with comments from Noralf and José Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Acked-by: Noralf Trønnes <noralf@tronnes.org> Cc: José Roberto de Souza <jose.souza@intel.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: Sean Paul <sean@poorly.run> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Andres Rodriguez <andresx7@gmail.com> Cc: Noralf Trønnes <noralf@tronnes.org> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190904143942.31756-1-daniel.vetter@ffwll.ch

Move object release into a separate worker. Releasing objects requires sending commands to the host.

virtio-gpu basically needs a sg_table for the bo, to tell the host where the backing pages for the object are. So the gem shmem helpers are a perfect fit. Some drm_gem_object_funcs need thin wrappers to update the host state, but otherwise the helpers handle everything just fine. Once the fencing was sorted the switch was surprisingly easy and for the most part just removing the ttm code. v4: fix drm_gem_object_funcs name.

Rework fencing workflow. Stop using ttm helpers, use the virtio_gpu_array_* helpers instead. Due to using the gem reservation object it is initialized and ready for use before calling ttm_bo_init. So we can simply use the standard fencing workflow and drop the tricky logic which checks whenever the command is in flight still. v6: rewrite most of the patch.

Rework fencing workflow, starting with virtio_gpu_execbuffer_ioctl. Stop using ttm helpers, use the virtio_gpu_array_* helpers (which work on the reservation objects directly) instead. Also store the object array in struct virtio_gpu_vbuffer, so we explicitly keep a reference of all buffers used instead of depending on ttm_bo_put() checking whenever the object is actually idle before releasing it. New workflow: (1) All gem objects needed by a command are added to a virtio_gpu_object_array. (2) All reservation objects will be locked (virtio_gpu_array_lock_resv). (3) virtio_gpu_fence_emit() completes fence initialization. (4) fence gets added to the objects, reservation objects are unlocked (virtio_gpu_array_add_fence, virtio_gpu_array_unlock_resv). (5) virtio command is submitted to the host. (6) The completion callback (virtio_gpu_dequeue_ctrl_func) will drop object references and free virtio_gpu_object_array. v6: rewrite most of the patch.

Unfortunately the DP MST helpers do not have much in the way of debugging utilities. So, let's add some! This adds basic debugging output for down sideband requests that we send from the driver, so that we can actually discern what's happening when sideband requests timeout. Since there wasn't really a good way of testing that any of this worked, I ended up writing simple selftests that lightly test sideband message encoding and decoding as well. Enjoy!
