This adds a function that also takes the console lock before calling fb_set_suspend() in contrast to drm_fb_helper_set_suspend() which is a plain wrapper around fb_set_suspend(). Resume is run asynchronously using a worker if the console lock is already taken. This is modelled after the i915 driver. Signed-off-by:

We always need to remove conflicting framebuffers if any other fb driver is enabled, and not just if we are setting up an fbdev ourselves. Unfortunately remove_conflicting_framebuffers() was incorrectly stubbed out if !fbdev rather than !fb leading to major memory corruption (and corrupt filesystems) upon boot.

The drivers have to modify the atomic plane state during the prepare_fb callback so they track allocations, reservations and dependencies for this atomic operation involving this fb. In particular, how else do we set the plane->fence from the framebuffer! Signed-off-by:

Move the documentation into Documentation/gpu, link it up and pull in the kernel doc. No actual text changes except that I did polish the kerneldoc a bit, especially for vga_client_register(). v2: Remove some rst from vga-switcheroo.rst that I don't understand, but which seems to be the reason why the new vgaarbiter.rst sometimes drops out of the sidebar index. v3: Drop one level of headings and clarify the vgaarb one a bit. v4: Fix some typos (Sean).

We seem to have a bit a mess in how to describe the bus formats, with a multitude of competing ways. Might be best to consolidate it all and use MEDIA_BUS_FMT_ also for the hdmi color formats and high color modes. Also move all the display_info related functions into drm_connector.c (there's only one) to group it all together. I did decided against also moving the edid related display info functions, they seem to fit better in drm_edid.c. Instead sprinkle a few cross references around. While at that reduce the kerneldoc for static functions, there's not point in documenting internals with that much detail really. v2: Fix typo and move misplaced hunk (Sean).

No one looks at it, only i915/gma500 lvds even bother to fill it out. I guess a very old plan was to use this for filtering modes, but that's already done within the edid parser. v2: Move misplaced hunk to this patch. Reviewed-by:

- Shuffle docs from drm-kms.rst into the structure docs where it makes sense. - Put the remaining bits into a new overview section.

They're only used internally within the dp helpers. Also nuke the kerneldoc (we only document the driver interface in the drm shared functions). And move the header file from the public include/ directory to the source files into drm_crtc_helper_internal.h, similar to how we already have drm_crtc_internal.h. While at it also move drm_fb_helper_modinit since that belongs in there, too. I noticed this all since I spotted kerneldoc which wasn't pulled into the rst templates. v2: Update Copyright date.

There's not much point in kerneldoc if it's not included: - It won't show up in the pretty html pages. - The comments itself won't get parsed, which means 0day won't pick up changes, resulting in stale docs fast. Also, uapi really should be core, not helpers, so move drm_blend.c to that. That also means that the zpos normilize function loses it's helper status (and we might as well call it always). For that, EXPORT_SYMBOL. Just spotted while integrating docs and noticing that one was missing. With sphinx there's really no excuse any more to not build the docs and make sure it's all nice! $ make DOCBOOKS="" htmldocs Cc: Marek Szyprowski <m.szyprowski@samsung.com> Cc: Benjamin Gaignard <benjamin.gaignard@linaro.org> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

Pulls in quite a lot of connector related structures (cmdline mode, force/status enums, display info), but I think that all makes perfect sense. Also had to move a few more core kms object stuff into drm_modeset.h. And as a first cleanup remove the kerneldoc for the 2 connector IOCTL - DRM core docs are aimed at drivers, no point documenting internal in excruciating detail. v2: And also pull in all the connector property code.

Also start with drm_modeset.h with the core bits, since we need to untangle this mess somehow. That allows us to move the drm_modes.h include to the right spot, except for the temporary connector status enum.

It was added way back together with the dirty_fb ioctl, but neither generic xfree86-modesetting nor the vmware driver use it. Everyone is supposed to just unconditionally call the dirtyfb when they do frontbuffer rendering. And since unused uabi is bad uabi (there's reasons we require open source userspace for everything) let's nuke this.

It's deprecated and only should be used by drivers which still use drm_platform_init, not by anyone else. And indeed it's entirely unused and can be nuked. This required a bit more fudging, but I guess kirin_dc_ops really wants to operate on the platform_device, not something else. Also bonus points for implementing abstraction, and then storing the vfunc in a global variable.
