This completes Emil's series of removing DRM_UNLOCKED from modern drivers. It's entirely cargo-culted since we ignore it on non-DRIVER_LEGACY drivers since: commit ea487835 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Sep 28 21:42:40 2015 +0200 drm: Enforce unlocked ioctl operation for kms driver ioctls Now justifying why we can do this for legacy drives too (and hence close the source of all the bogus copypasting) is a bit more involved. DRM_UNLOCKED was introduced in: commit ed8b6704 Author: Arnd Bergmann <arnd@arndb.de> Date: Wed Dec 16 22:17:09 2009 +0000 drm: convert drm_ioctl to unlocked_ioctl As a immediate hack to keep i810 happy, which would have deadlocked without this trickery. The old BKL is automatically dropped in schedule(), and hence the i810 vs. mmap_sem deadlock didn't actually cause a real deadlock. But with a mutex it would. The solution was to annotate these as DRM_UNLOCKED and mark i810 unsafe on SMP machines. This conversion caused a regression, because unlike the BKL a mutex isn't dropped over schedule (that thing again), which caused a vblank wait in one thread to block the entire desktop and all its apps. Back then we did vblank scheduling by blocking in the client, awesome isn't it. This was fixed quickly in (ok not so quickly, took 2 years): commit 8f4ff2b0 Author: Ilija Hadzic <ihadzic@research.bell-labs.com> Date: Mon Oct 31 17:46:18 2011 -0400 drm: do not sleep on vblank while holding a mutex All the other DRM_UNLOCKED annotations for all the core ioctls was work to reach finer-grained locking for modern drivers. This took years, and culminated in: commit fdd5b877 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sat Dec 10 22:52:54 2016 +0100 drm: Enforce BKL-less ioctls for modern drivers DRM_UNLOCKED was never required by any legacy drivers, except for the vblank_wait IOCTL. Therefore we will not regress these old drivers by going back to where we've been in 2011. For all modern drivers nothing will change. To make this perfectly clear, also add a comment to DRM_UNLOCKED. v2: Don't forget about drm_ioc32.c (Michel).

The idea is that gem_prime_export is deprecated in favor of obj_funcs.export. That's much easier to do if both have matching function signatures. Reviewed-by:

This is a no-op on atomic drivers because with atomic it's simply too complicated to get all the locking and workers and nonblocking synchronization correct, from essentially an NMI context. Well, too complicated = impossible. Also, omapdrm never implemented the mode_set_base_atomic hook, so I kinda wonder why this was ever added. Drop the hooks. Reviewed-by:

Split out to make the functional changes stick out more. All places where DRIVER_PRIME was used have been removed in previous patches already. v2: amdgpu gained DRIVER_SYNCOBJ_TIMELINE. v3: amdgpu lost DRIVER_SYNCOBJ_TIMELINE. v4: Don't add a space in i915_drv.c (Sam) v5: Add note that previous patches removed all the DRIVER_PRIME users already (Emil). v6: Fixupe ingenic (new driver) while applying.

Drivers must fill out the handle_to_fd and fd_to_handle hooks to enable export/import prime functionality already. The additional DRIVER_PRIME flag doesn't serve any real purpose, since the overall flag doesn't even tell you whether import or export or maybe even both is supported. Ditch it. This patch just makes it defunct, subsequent patches will remove it from all the drivers. Note this changes the userspace visible errno in some situations from EOPNOTSUPP to ENOSYS. Userspace already needs to treat both as "no prime support", so this should break anything. v2: Improve commit message as suggested by Emil Reviewed-by:

Yes this is a bit a big patch, but since it's essentially a complete rewrite of all the prime docs I didn't see how to better split it up. Changes: - Consistently point to drm_gem_object_funcs as the preferred hooks, where applicable. - Document all the hooks in &drm_driver that lacked kerneldoc. - Completely new overview section, which now also includes the cleaned up lifetime/reference counting subchapter. I also mentioned the weak references in there due to the lookup caches. - Completely rewritten helper intro section, highlight the import/export related functionality. - Polish for all the functions and more cross references. I also sprinkled a bunch of todos all over. Most important: 0 code changes in here. The cleanup motivated by reading and improving all this will follow later on. v2: Actually update the prime helper docs. Plus add a few FIXMEs that I won't address right away in subsequent cleanup patches. v3: - Split out the function moving. This patch is now exclusively documentation changes. - Typos and nits (Sam). v4: Polish suggestions from Noralf. Acked-by:

Add a KMS driver for the Ingenic JZ47xx family of SoCs. This driver is meant to replace the aging jz4740-fb driver. This driver does not make use of the simple pipe helper, for the reason that it will soon be updated to support more advanced features like multiple planes, IPU integration for colorspace conversion and up/down scaling, support for DSI displays, and TV-out and HDMI outputs. Notes: v2: - Remove custom handling of panel. The panel is now discovered using the standard API. - Lots of small tweaks suggested by upstream v3: - Use devm_drm_dev_init() - Update compatible strings to -lcd instead of -drm - Add destroy() callbacks to plane and crtc - The ingenic,lcd-mode is now read from the bridge's DT node v4: Remove ingenic,lcd-mode property completely. The various modes are now deduced from the connector type, the pixel format or the bus flags. v5: - Fix framebuffer size incorrectly calculated for 24bpp framebuffers - Use 32bpp framebuffer instead of 16bpp, as it'll work with both 16-bit and 24-bit panel - Get rid of drm_format_plane_cpp() which has been dropped upstream - Avoid using drm_format_info->depth, which is deprecated.
