Merge tag 'drm-misc-next-2023-07-13' of git://anongit.freedesktop.org/drm/drm-misc into drm-next
drm-misc-next for v6.6: UAPI Changes: * fbdev: * Make fbdev userspace interfaces optional; only leaves the framebuffer console active * prime: * Support dma-buf self-import for all drivers automatically: improves support for many userspace compositors Cross-subsystem Changes: * backlight: * Fix interaction with fbdev in several drivers * base: Convert struct platform.remove to return void; part of a larger, tree-wide effort * dma-buf: Acquire reservation lock for mmap() in exporters; part of an on-going effort to simplify locking around dma-bufs * fbdev: * Use Linux device instead of fbdev device in many places * Use deferred-I/O helper macros in various drivers * i2c: Convert struct i2c from .probe_new to .probe; part of a larger, tree-wide effort * video: * Avoid including <linux/screen_info.h> Core Changes: * atomic: * Improve logging * prime: * Remove struct drm_driver.gem_prime_mmap plus driver updates: all drivers now implement this callback with drm_gem_prime_mmap() * gem: * Support execution contexts: provides locking over multiple GEM objects * ttm: * Support init_on_free * Swapout fixes Driver Changes: * accel: * ivpu: MMU updates; Support debugfs * ast: * Improve device-model detection * Cleanups * bridge: * dw-hdmi: Improve support for YUV420 bus format * dw-mipi-dsi: Fix enable/disable of DSI controller * lt9611uxc: Use MODULE_FIRMWARE() * ps8640: Remove broken EDID code * samsung-dsim: Fix command transfer * tc358764: Handle HS/VS polarity; Use BIT() macro; Various cleanups * Cleanups * ingenic: * Kconfig REGMAP fixes * loongson: * Support display controller * mgag200: * Minor fixes * mxsfb: * Support disabling overlay planes * nouveau: * Improve VRAM detection * Various fixes and cleanups * panel: * panel-edp: Support AUO B116XAB01.4 * Support Visionox R66451 plus DT bindings * Cleanups * ssd130x: * Support per-controller default resolution plus DT bindings * Reduce memory-allocation overhead * Cleanups * tidss: * Support TI AM625 plus DT bindings * Implement new connector model plus driver updates * vkms * Improve write-back support * Documentation fixes Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> From: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20230713090830.GA23281@linux-uq9g

+Remove driver dependencies on FB_DEVICE
+---------------------------------------
+
+A number of fbdev drivers provide attributes via sysfs and therefore depend
+on CONFIG_FB_DEVICE to be selected. Review each driver and attempt to make
+any dependencies on CONFIG_FB_DEVICE optional. At the minimum, the respective
+code in the driver could be conditionalized via ifdef CONFIG_FB_DEVICE. Not
+all drivers might be able to drop CONFIG_FB_DEVICE.

+ * DOC: Overview
+ *
+ * This component mainly abstracts the retry loop necessary for locking
+ * multiple GEM objects while preparing hardware operations (e.g. command
+ * submissions, page table updates etc..).
+ *
+ * If a contention is detected while locking a GEM object the cleanup procedure
+ * unlocks all previously locked GEM objects and locks the contended one first
+ * before locking any further objects.
+ *
+ * After an object is locked fences slots can optionally be reserved on the
+ * dma_resv object inside the GEM object.
+ *
+ * A typical usage pattern should look like this::
+ *
+ * struct drm_gem_object *obj;
+ * struct drm_exec exec;
+ * unsigned long index;
+ * int ret;
+ *
+ * drm_exec_init(&exec, DRM_EXEC_INTERRUPTIBLE_WAIT);
+ * drm_exec_until_all_locked(&exec) {
+ * ret = drm_exec_prepare_obj(&exec, boA, 1);
+ * drm_exec_retry_on_contention(&exec);
+ * if (ret)
+ * goto error;
+ *
+ * ret = drm_exec_prepare_obj(&exec, boB, 1);
+ * drm_exec_retry_on_contention(&exec);
+ * if (ret)
+ * goto error;
+ * }
+ *
+ * drm_exec_for_each_locked_object(&exec, index, obj) {
+ * dma_resv_add_fence(obj->resv, fence, DMA_RESV_USAGE_READ);
+ * ...
+ * }
+ * drm_exec_fini(&exec);
