I plan to usurp the short name of struct fence for a core kernel struct, and so I need to rename the specialised fence/timeline for DMA operations to make room. A consensus was reached in https://lists.freedesktop.org/archives/dri-devel/2016-July/113083.html that making clear this fence applies to DMA operations was a good thing. Since then the patch has grown a bit as usage increases, so hopefully it remains a good thing!

drm_atomic_state has a complicated single owner model that tracks the single reference from allocation through to destruction on another thread - or perhaps on a local error path. We can simplify this tracking by using reference counting (at a cost of a few more atomics).

Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter of the helper drm_atomic_helper_commit_planes() if the relevant display controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes when the CRTC is disabled. The helper would skip the ->atomic_disable call for a plane if the CRTC of the old plane state needs a modesetting operation. Of course, the drivers need to disable the planes in their CRTC disable callbacks since no one else would do that.

Currently, the helper drm_atomic_helper_disable_planes_on_crtc() calls ->atomic_disable for all planes _to be_ enabled on a particular CRTC. This is obviously wrong for those planes which are not scanning out frames when the helper is called. Instead, it's sane to disable active planes of old_crtc_state in the helper.

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).

This patch adds an atomic encoder mode setting variant that passes the crtc state (which contains the modes) and the connector state. atomic_enable/disable variants that additionally pass crtc and connector state don't seem to be necessary for any current driver. mode_fixup already has an atomic equivalent in atomic_check.

stall_checks carefully picked out the right commit to stall on, then promptly used the wrong variable. Due to the break in the next loop iteration this could be the 3rd commit, or if the list only has 2 entries commit would now point into the struct drm_crtc itself, at some offset. Hilarity eventually ensues. For added safety, also break right away instead of iterating once more, but the real fix is waiting on stall_commit instead of commit.

Design ideas: - split up the actual commit into different phases, and have completions for each of them. This will be useful for the future when we want to interleave phases much more aggressively, for e.g. queue depth > 1. For not it's just a minimal optimization compared to current common nonblocking implementation patterns from drivers, which all stall for the entire commit to complete, including vblank waits and cleanups. - Extract a separate atomic_commit_hw hook since that's the part most drivers will need to overwrite, hopefully allowing even more shared code. - Enforce EBUSY seamntics by attaching one of the completions to the flip_done vblank event. Side benefit of forcing atomic drivers using these helpers to implement event handlign at least semi-correct. I'm evil that way ;-) - Ridiculously modular, as usual. - The main tracking unit for a commit stays struct drm_atomic_state, and the ownership rules for that are unchanged. Ownership still gets transferred to the driver (and subsequently to the worker) on successful commits. What is added is a small, per-crtc, refcounted structure to track pending commits called struct drm_crtc_commit. No actual state is attached to that though, it's purely for ordering and waiting. - Dependencies are implicitly handled by assuming that any CRTC part of &drm_atomic_state is a dependency, and that the current commit must wait for any commits to complete on those CRTC. This way drivers can easily add more depencies using drm_atomic_get_crtc_state(), which is very natural since in most case a dependency exists iff there's some bit of state that needs to be cross checked. Removing depencies is not possible, drivers simply need to be careful to not include every CRTC in a commit if that's not necessary. Which is a good idea anyway, since that also avoids ww_mutex lock contention. - Queue depth > 1 sees some prep work in this patch by adding a stall paramater to drm_atomic_helper_swap_states(). To be able to push commits entirely free-standing and in a deeper queue through the back-end the driver must not access any obj->state pointers. This means we need to track the old state in drm_atomic_state (much easier with the consolidated arrays), and pass them all explicitly to driver backends (this will be serious amounts of churn). Once that's done stall can be set to false in swap_states. v2: Dont ask for flip_done signalling when the CRTC is off and stays off: Drivers don't handle events in that case. Instead complete right away. This way future commits don't need to have special-case logic, but can keep blocking for the flip_done completion. v3: Tons of fixes: - Stall for preceeding commit for real, not the current one by accident. - Add WARN_ON in case drivers don't fire the drm event. - Don't double-free drm events. v4: Make legacy cursor not stall. v5: Extend the helper hook to cover the entire commit tail. Some drivers need special code for cleanup and vblank waiting, this makes it a bit more useful. Inspired by the rockchip driver. v6: Add WARN_ON to catch drivers who forget to send out the drm event. v7: Fixup the stalls in swap_state for real!! v8: - Fixup trailing whitespace, spotted by Maarten. - Actually wait for flip_done in cleanup_done, like the comment says we should do. Thanks a lot for Tomeu for helping with debugging this on. v9: Now with awesome kerneldoc! v10: Split out drm_crtc_commit tracking infrastructure. v: - Add missing static (Gustavo). - Split out the sync functions, only do the actual nonblocking logic in this patch (Maarten).

To facilitate easier reviewing this is split out from the overall nonblocking commit rework. It just rolls out the helper functions and uses them in the main drm_atomic_helper_commit() function to make it clear where in the flow they're used.

It's kinda pointless to have 2 separate mallocs for these. And when we add more per-plane state in the future it's even more pointless. Right now there's no such thing planned, but both Gustavo's per-crtc fence patches, and some nonblocking commit helpers I'm playing around with will add more per-crtc stuff. It makes sense to also consolidate planes, just for consistency. In the future we can use this to store a pointer to the preceeding state, making an atomic update entirely free-standing.

Mostly this is unexpected indents. But really it's just a demonstration for my patch, all these issues have been found&fixed using the correct source file and line number support I just added. All line numbers have been perfectly accurate. One issue looked a bit fishy in intel_lrc.c, where I don't quite grok what sphinx is unhappy about. But since that file looks like it has never seen a proper kernel-doc parser I figured better to fix in a separate path. v2: Use fancy new &drm_device->struct_mutex linking (Jani).

This avois leaking drm_atomic_state internals into the helpers. The only place where this still happens after this patch is drm_atomic_helper_swap_state(). It's unavoidable there, and maybe a good indicator we should actually move that function into drm_atomic.c.

When a CRTC is going to be disabled, it's state may contain a display mode with zeroed content. This could be reproduced by HDMI cable hotplug out operation with legacy fbdev support in dual display cases. It would confuse driver's CRTC callback ->mode_fixup and make the total state be rejected. So, let's don't call the callback for the CRTC.

It's unused, and really this helper should only look at the state structure and nothing else. Note that this conflicts with a patch from Dave that adds refcounting to drm_connectors. It's not yet clear whether the check Dave adds for connector != NULL is really needed or the right check. v2: Fix commmit message (Laurent).

This is the first step of renaming async commit to nonblocking commit. The flag passed by userspace is NONBLOCKING, and async has a different meaning for page flips, where it means as soon as possible. Fixing up comments in drm core is done manually, to make sure I didn't miss anything. For drivers, the following cocci script is used to rename bool async to bool nonblock: @@ identifier I =~ "^async"; identifier func; @@ func(..., bool - I + nonblock , ...) { <... - I + nonblock ...> } @@ identifier func; type T; identifier I =~ "^async"; @@ T func(..., bool - I + nonblock , ...); Thanks to Tvrtko Ursulin for the cocci script.
