Provides a default CRTC state check handler for CRTCs that only have one primary plane attached. There are some drivers that duplicate this logic in their helpers, such as simpledrm and ssd130x. Factor out this common code into a CRTC helper and make drivers use it. Signed-off-by:

There's no need to add planes to the atomic state. Remove the call to drm_atomic_add_affected_planes() from ssd130x. On full modesets, the DRM helpers already add a CRTC's planes to the atomic state; see drm_atomic_helper_check_modeset(). There's no reason to call drm_atomic_add_affected_planes() unconditionally in the CRTC's atomic_check() in ssd130x. It's also too late, as the atomic_check() of the added planes will not be called before the commit. Suggested-by:

Soft reset during tc_bridge_enable() is triggered by setting all available reset control bits in the SYSRST register. But as noted in the data sheet resetting the i2c-slave controller should be only done over DSI and is only useful for chip debugging. So do not set RSTI2CS (bit0). Signed-off-by:

PAL-M is a Brazilian analog TV standard that uses a PAL-style chroma subcarrier at 3.575611[888111] MHz on top of 525-line (480i60) timings. This commit makes the driver actually use the proper VEC preset for this mode instead of just changing PAL subcarrier frequency. Acked-by:

It is fairly common for named video modes to contain dashes (e.g. "tt-mid" on Atari, "dblntsc-ff" on Amiga). Currently such mode names are not recognized, as the dash is considered to be a separator between mode name and bpp. Fix this by skipping any dashes that are not followed immediately by a digit when looking for the separator.

Some video= options might have a value that contains a dash. However, the command line parsing mode considers all dashes as the separator between the mode and the bpp count. Let's rework the parsing code a bit to only consider a dash as the bpp separator if it before a comma, the options separator. A follow-up patch will add a unit-test for this once such an option is introduced. Reviewed-by:

The subconnector property was created by drm_mode_create_tv_properties(), but wasn't exposed to the userspace through the generic atomic_get/set_property implementation, and wasn't stored in any generic state structure. Let's solve this. Reviewed-by:

There is two TV subconnector related properties registered by drm_mode_create_tv_properties(): subconnector and select subconnector. While the select subconnector property is stored in the kernel by the drm_tv_connector_state structure, the subconnector property isn't stored anywhere. Worse, the select subconnector property is stored in a field called subconnector, creating some ambiguity about which property content we're accessing. Let's rename that field to one called select_subconnector to make it move obvious what it's about. Acked-by:

We currently have two sets of TV properties. The first one is there to deal with analog TV properties, creating properties such as the TV mode, subconnectors, saturation, hue and so on. It's created by calling the drm_mode_create_tv_properties() function. The second one is there to deal with properties that might be useful on a TV, creating the overscan margins for example. It's created by calling the drm_mode_create_tv_margin_properties(). However, we also have a drm_atomic_helper_connector_tv_reset() function that will reset the TV margin properties to their default values, and thus is supposed to be called for the latter set. This creates an ambiguity due to the inconsistent naming. We can thus rename the drm_atomic_helper_connector_tv_reset() function to drm_atomic_helper_connector_tv_margins_reset() to remove that ambiguity and hopefully make it more obvious. Acked-by:

Rename the atomic helper function drm_atomic_helper_check_crtc_state() to drm_atomic_helper_check_crtc_primary_plane() and only check for an attached primary plane. Adapt callers. Instead of having one big function to check for various CRTC state conditions, we rather want smaller functions that drivers can pick individually. v5: * rebase on top of udl changes Signed-off-by:

In drm_atomic_helper_check_crtc_state(), do not add a new plane state to the global state if it does not exist already. Adding a new plane state will result in overhead for the plane during the atomic-commit step. For the test in drm_atomic_helper_check_crtc_state() to succeed, it is important that the CRTC has an enabled primary plane after the commit. Simply testing the CRTC state's plane_mask for a primary plane is sufficient. Note that the helper still only tests for an attached primary plane. Drivers have to ensure that the plane contains valid pixel information. v5: * fix commit description (Javier) v3: * test for a primary plane in plane_mask (Ville) v2: * remove unnecessary test for plane->crtc (Ville) * inline drm_atomic_get_next_plane_state() (Ville) * acquire plane lock before accessing plane->state (Ville) Signed-off-by:

Use a damage iterator to process damage areas individually. Merging damage areas can result in large updates of unchanged framebuffer regions. As USB is rather slow, it's better to process damage areas individually and hence minimize USB-transfered data. As part of the change, move drm_gem_fb_{begin,end}_cpu_access() into the plane's atomic_update helper. To avoid overhead and intermediate writers, we want to synchronize buffers and reserve access only once before copying damage areas of the framebuffer. v2: * clarify commit message (Javier) Signed-off-by: -

Replace simple-KMS helpers with regular atomic-modesetting helpers. The simple-KMS helpers introduce a mid-layer abstraction without added functionality. Using regular atomic helpers makes the driver's implementation more discoverable and simplifies code sharing.

The drm_atomic_helper_damage_merged() helper merges all the damage clips into one rectangle. If there are multiple damage clips that aren't close to each other, the resulting rectangle could be quite big. Instead of using that function helper, iterate over all the damage clips and update them one by one. Suggested-by:

The current ast driver only supports legacy gamma interface. This also fixes a Gnome3/Wayland error which incorrectly adds gamma to atomic commit: "Page flip discarded: CRTC property (GAMMA_LUT) not found" I only tested remotely, so I wasn't able to check that it had an effect on the VGA output. But when activating "Night Light" in Gnome, ast_crtc_load_lut() is called. v2: use the same functions as mgag200. handle 16bits color mode. v3: Check gamma_lut size in atomic check. v4: revert 16bits mode, v1 was correct. make sure gamma table are set when primary plane format changes. remove rgb888 format that is not used.
