* drm: Add helper iterator functions for plane fb_damage_clips blobDeepak Rawat2018-12-052-1/+57
| | | | | | | | | | | | | | | | With fb_damage_clips blob property in drm_plane_state, this patch adds helper iterator to traverse the damage clips that lie inside plane src. Iterator will return full plane src as damage in case need full plane update or damage is not specified. v2: - Plane src clipping correction - Handle no plane update case in iter_next Signed-off-by: Deepak Rawat <drawat@vmware.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com>

* drm: Add a new plane property to send damage during plane updateLukasz Spintzyk2018-12-053-0/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | FB_DAMAGE_CLIPS is an optional plane property to mark damaged regions on the plane in framebuffer coordinates of the framebuffer attached to the plane. The layout of blob data is simply an array of "struct drm_mode_rect". Unlike plane src coordinates, damage clips are not in 16.16 fixed point. As plane src in framebuffer cannot be negative so are damage clips. In damage clip, x1/y1 are inclusive and x2/y2 are exclusive. This patch also exports the kernel internal drm_rect to userspace as drm_mode_rect. This is because "struct drm_clip_rect" is not sufficient to represent damage for current plane size. Driver which are interested in enabling FB_DAMAGE_CLIPS property for a plane should enable this property using drm_plane_enable_damage_clips. v2: - Input validation on damage clips against framebuffer size. - Doc update, other minor changes.

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(). This gets rid of the behavior of allowing DPMS On<->Off, but that should be fine as it's more consistent with the UAPI we had before - danvet - s/drm_connector_unregistered/drm_connector_is_unregistered/ - danvet - Update documentation, fix some typos.

So, let's move for now with the information we trust more: the number of EUs. So we are able to propagate this change across the stack without getting stuck forever.

The main benefit is for drivers that support more than one type of memory (shmem,vram,cma) for their buffers depending on the hardware it runs on. With the callbacks attached to the GEM object itself, it is easier to have core helpers for the the various buffer types. The driver only has to make the decision about buffer type on GEM object creation and all other callbacks can be handled by the chosen helper. drm_driver->gem_prime_res_obj has not been added since there's a todo to put a reservation_object into drm_gem_object. v3: Add todo entry v2: Drop drm_gem_object_funcs->prime_mmap in favour of drm_gem_prime_mmap() (Daniel Vetter) v1: - drm_gem_object_funcs.map -> .prime_map let it only do PRIME mmap like the function it superseeds (Daniel Vetter) - Flip around the if ladders and make obj->funcs the first choice highlighting the fact that this the new default way of doing it (Daniel Vetter) Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Christian König <christian.koenig@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181110145647.17580-4-noralf@tronnes.org

What's implemented here is to add three new members to drm_format_info that could describe such formats: - char_per_block[3] - block_w[3] - block_h[3] char_per_block will be put in a union alongside cpp, for transparent compatibility with the existing format descriptions. Regarding, block_w and block_h they are intended to be used through their equivalent getters drm_format_info_block_width / drm_format_info_block_height, the reason of the getters is to abstract the fact that for normal formats block_w and block_h will be unset/0, but the methods will be returning 1. Additionally, convenience function drm_format_info_min_pitch had been added that computes the minimum required pitch for a given pixel format and buffer width. Using that the following drm core functions had been updated to generically handle both block and non-block formats: - drm_fb_cma_get_gem_addr: for block formats it will just return the beginning of the block. - framebuffer_check: Use the newly added drm_format_info_min_pitch. - drm_gem_fb_create_with_funcs: Use the newly added drm_format_info_min_pitch. - In places where is not expecting to handle block formats, like fbdev helpers I just added some warnings in case the block width/height are greater than 1. Changes since v3: - Add helper function for computing the minimum required pitch. - Improve/cleanup documentation Changes since v8: - Fixed build on 32bits arm architectures, with: - return DIV_ROUND_UP((u64)buffer_width * info->char_per_block[plane], + return DIV_ROUND_UP_ULL((u64)buffer_width * info->char_per_block[plane], Reviewed-by: Brian Starkey <brian.starkey@arm.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Alexandru Gheorghe <alexandru-cosmin.gheorghe@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181101170055.5433-1-alexandru-cosmin.gheorghe@arm.com

This will require additional implementation-specific code to look up the slave instance and do specific setup. Also will probably need code in the specific crtcs as dual-dsi does not equal two separate dsi outputs. To activate, the implementation-specific code should set the slave using dw_mipi_dsi_set_slave() before calling __dw_mipi_dsi_bind(). v2: - expect real interface number of lanes - keep links to both master and slave v3: - remove unneeded separate variables - remove unneeded second slave settings - disable slave before master - lane-sum calculation comments Signed-off-by: Nickey Yang <nickey.yang@rock-chips.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de> Tested-by: Philippe Cornu <philippe.cornu@st.com> Reviewed-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181001123845.11818-7-heiko@sntech.de

When the panel-driver is build as a module it currently fails hard as the panel cannot be probed directly: dw_mipi_dsi_bind() __dw_mipi_dsi_probe() creates dsi bus creates panel device triggers panel module load panel not probed (module not loaded or panel probe slow) drm_bridge_attach fails with -EINVAL due to empty panel_bridge Additionally the panel probing can run concurrently with dsi bringup making it possible that the panel can already be found but dsi-attach hasn't finished running. To solve that cleanly we may want to only create the component after the panel has finished probing, by calling component_add from the host-attach dsi callback. As that is specific to glue drivers, add a new struct for host_ops so that glue drivers can tell the bridge to call specific functions after the common host-attach and before the common host-detach run.

So this is happening on each try of master bringup possibly slowing down things a lot. Drivers using the component framework may instead want to call dw_mipi_dsi_probe separately in their probe function to setup resources early. That way the dsi bus also gets created earlier and also not recreated on each bind-try, so that attached panels can load their modules and be probed way before the bridge-attach in the bind call. So drop the call to __dw_mipi_dsi_probe and modify the function to take a struct dw_mipi_dsi instead of the platform-device.
