drm/udl: Untangle .get_modes() and .detect_ctx()

2024-05-13T11:35:52Z

Provide separate implementations of .get_modes() and .detect_ctx() from struct drm_connector. Switch to struct drm_edid. Udl's .detect() helper used to fetch the EDID from the adapter and the .get_modes() helper provided display modes from the data. But this relied on the DRM helpers to call the functions in the correct order. When no EDID could be retrieved, .detect() regularly printed a warning to the kernel log. Switching to the new helpers around struct drm_edid separates both from each other. The .get_modes() helper now fetches the EDID by itself and the .detect_ctx() helper only tests for its presence. The patch does a number of things to implement this. - Move udl_get_edid_block() to udl_edid.c and rename it to udl_read_edid_block(). Then use the helper to implement probing in udl_probe_edid() and reading in udl_edid_read(). The latter helper is build on top of DRM helpers. - Replace the existing code in .get_modes() and .detect() with udl's new EDID helpers. The new code behaves like DRM's similar DDC-based helpers. Instead of .detect(), udl now implements .detect_ctx(). - Remove the edid data from struct udl_connector. The field cached the EDID data between calls to .detect() and .get_modes(), but is now unused. v3: - implement udl_probe_edid() with memchr_inv() (Jani) v2: - implement udl_probe_edid() within udl - reword commit description Signed-off-by: Thomas Zimmermann Reviewed-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20240510154841.11370-5-tzimmermann@suse.de

drm/udl: Use GEM vmap/mmap function from SHMEM helpers

2020-06-10T08:17:21Z

The udl driver contains an implementation of GEM vmap and mmap operations that is identical to the common SHMEM helper; except that udl's code uses cached pages by default. Convert udl to regular SHMEM helper functions. There's no reason to have udl behave differently from all other SHMEM drivers. The udl driver uses the SHMEM helper to enable caching. v3: * rebased onto Daniel's shmem untangle series v2: * implement .gem_create_object with SHMEM helper Signed-off-by: Thomas Zimmermann Reviewed-by: Emil Velikov Link: https://patchwork.freedesktop.org/patch/msgid/20200609090820.20256-3-tzimmermann@suse.de

drm/udl: Convert to struct drm_simple_display_pipe

2019-12-11T16:02:16Z

Udl has a single display pipeline with a primary plane; perfect for simple-pipe helpers. Convert it over. The old encoder and CRTC code becomes unused and obsolete. Exported formats for the primary plane are RGB565 and XRGB8888, with the latter being emulated. The 16-bit format is the default and what is used when communicating with the device. This patch enables atomic modesetting for udl devices. v3: * remove unused field crtc from struct udl_device * set crtc_state->no_vblank at beginning of enable() v2: * move suspend/resume changes into separate patch * remove non-atomic code Signed-off-by: Thomas Zimmermann Reviewed-by: Emil Velikov Link: https://patchwork.freedesktop.org/patch/msgid/20191210084905.5570-3-tzimmermann@suse.de
