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: -

Add drm_dev_enter() and drm_dev_exit() to the various modesetting functions that interact with the device. After hot-unplugging the device, these functions will return early. So far, the udl driver relied on USB interfaces to handle unplugging of the device. 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 conversion effectively open-codes the simple-KMS functions and data structure within udl. No functional changes. v2: * don't use the atomic_disable plane helper Signed-off-by:

The tile status modifiers can be combined with all of the usual color buffer modifiers. When they are present an additional plane is added to the surfaces to share the tile status buffer. The TS modifiers describe the interpretation of the tag bits in this buffer. Signed-off-by:

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.

Get rid of the confusing version_greater() stuff and simply compare edid->revision directly everwhere. Half the places already did it this way, and since we actually reject any EDID with edid->version!=1 it's a perfectly sane thing to do. Reviewed-by:

For EDID 1.4 the first detailed timing is always preferred, for older EDIDs there was a feature flag to indicate the same. While correct, the code setting that up is rather confusing. Restate it in a slightly more straightforward manner. Reviewed-by:

Ville Syrjälä authored
Prefer the timing formula indicated by the range descriptor for generating the non-DMT standard timings. Previously we just used CVT for all EDID 1.4 continuous frequency displays without even checking if the range descriptor indicates otherwise. Now we check the range descriptor first, and fall back to CVT if nothing else was indicated. EDID 1.4 more or less deprecates GTF/GTF2 but there are still a lot of 1.4 EDIDs out there that don't advertise CVT support, so seems safer to use the formula the EDID actually reports as supported. For EDID 1.3 we use GTF2 if indicated (as before), and for EDID 1.2+ we now just use GTF without even checking the feature flag. There seem to be quite a few EDIDs out there that don't set the GTF feature flag but still include a GTF range descriptor and non-DMT standard timings. This to me seems to be roughly what appendix B of EDID 1.4 suggests should be done. Reviewed-by:

Since we only use the parsed vrefresh range to determine if VRR should be supported we should only accept continuous frequency displays here.
