It's redundant, drm core guarantees that state->fb is set iff state->crtc is set. v2: I had a misconception about simple helpers here and thought they filter this out. They don't. Issue reported by Eugeniy. Acked-by:

Really straighforward, only slight issue is that the sim connector is created after the pipe is set up, so can't use the helpers perfectly yet. Subsequent patches will fix that. Aside from lots of deleting code no functional changes in here. v2: Delete now unused crtc funcs (0day) v3: Move endcoder setup removal to right patch (Sam) Acked-by:

Simple pipe helpers only have an enable and disable hook, no more mode_set_nofb. Call it from our enable hook to align with that conversions. Atomic helpers always call mode_set_nofb and enable together, so there's no functional change here. Acked-by:

With autocleanup through drm_device management we can delete all the code. Possible now that there's no confusion against devm_kzalloc'ed structures anymore. I inlined arcpgu_setup_mode_config because it's tiny and the newly needed return value handling would have been more ... Acked-by:

This is a prep step to convert arc over to the simple kms helpers, for now we just use this as an embedding container to drop all the various allocations. Big change is the removal of the various devm_kzalloc, which have the wrong lifetimes anyway. Acked-by:

dma-buf importing was reworked in commit 7d2cd72a ("drm/shmem-helpers: Simplify dma-buf importing"). Before that commit drm_gem_shmem_prime_import_sg_table() did set ->pages_use_count=1 and drm_gem_shmem_vunmap_locked() could call drm_gem_shmem_put_pages() unconditionally. Now without the use count set, put pages is called also on dma-bufs. Fix this by only putting pages if it's not imported. Signed-off-by:

Only planes' prepare_fb and cleanup_fb, and encoders' atomic_check and atomic_mode_set hooks remain with an object state and not the global drm_atomic_state. prepare_fb and cleanup_fb operate by design on a given state and depending on the calling site can operate on either the old or new state, so it doesn't really make much sense to convert them. The encoders' atomic_check and atomic_mode_set operate on the CRTC and connector state connected to them since encoders don't have a state of their own. Without those state pointers, we would need to get the CRTC through the drm_connector_state crtc pointer. However, in order to get the drm_connector_state pointer, we would need to get the connector itself and while usually we have a single connector connected to the encoder, we can't really get it from the encoder at the moment since it could be behind any number of bridges. While this could be addressed by (for example) listing all the connectors and finding the one that has the encoder as its source, it feels like an unnecessary rework for something that is slowly getting replaced by bridges. Since all the users that matter have been converted, let's remove the TODO item. Acked-by:

Many drivers reference the plane->state pointer in order to get the current plane state in their atomic_update or atomic_disable hooks, which would be the new plane state in the global atomic state since _swap_state happened when those hooks are run.

According to the CTA 861.G spec, HDMI_STATIC_METADATA_TYPE1 is not 1, but zero, so fix this enum. While this doesn't cause problems in the kernel yet, as the constant isn't actively used by drivers yet, it did create confusion while debugging HDR problems in yours truly, and also potential bugs in userspace components, as the wrong enum propagates to components, e.g., like it did already into intel-gpu-tools (tests/kms_hdr.c) or is used as wrong reference when writing future new userspace HDR components like compositors.

This is needed to signal the fences from page flips, annotate it accordingly. We need to annotate entire timer callback since if we get stuck anywhere in there, then the timer stops, and hence fences stop. Just annotating the top part that does the vblank handling isn't enough. Tested-by:

Like the helpers, nothing special. Well except not, because we the critical section extends until after hw_done(), since that's the last thing which could hold up a subsequent atomic commit. That means the wait_for_flip_done is included, but that's not a problem, we're allowed to call dma_fence_wait() from signalling critical sections. Even on our own fence (which this does), it's just a bit confusing. But in a way those last 2 function calls are already part of the fence signalling critical section for the next atomic commit. Reading this I'm wondering why komeda waits for flip_done() before calling hw_done(), which is a bit backwards (but hey hw can be special). Might be good to throw a comment in there that explains why, because the original commit that added this just doesn't. v2: Small rebase Reviewed-by: James Qian Wang <james.qian.wang@arm.com> (v1) Cc: "James (Qian) Wang" <james.qian.wang@arm.com> Cc: Liviu Dudau <liviu.dudau@arm.com> Cc: Mihail Atanassov <mihail.atanassov@arm.com> Signed-off-by:

One of these drivers that predates the nonblocking support in helpers, and hand-rolled its own thing. Entirely not anything specific here, we can just delete it all and replace it with the helper version. Could also perhaps use the drm_mode_config_helper_suspend/resume stuff, for another few lines deleted. But I'm not looking at that stuff, I'm just going through all the atomic commit functions and make sure they have properly annotated dma-fence critical sections everywhere. v2: - Also delete the workqueue (Sam) - drop the @commit kerneldoc, I missed that one.

Nothing special, just put the end right after hw_done(). Note that in one path there's a wait for the flip/update to complete. But as far as I understand from comments and code that's only relevant for modesets, and skipped if there wasn't a modeset done on a given crtc. For a bit more clarity pull the hw_done() call out of the if/else, that way it's a bit clearer flow. But happy to shuffle this around as is seen fit. Reviewed-by:

Ends right after hw_done(), totally standard case. Acked-by:

The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting, but currently located next to framebuffer helpers. Move it to GEM atomic helpers, rename it slightly and adopt the drivers. Same for the rsp simple-pipe helper. Compile-tested with x86-64, aarch64 and arm. The patch is fairly large, but there are no functional changes. v3: * remove out-comented line in drm_gem_framebuffer_helper.h (Maxime) v2: * rename to drm_gem_plane_helper_prepare_fb() (Daniel) * add tutorial-style documentation Signed-off-by:

a connector is leaked upon module unload, it seems that we should do similar to sample driver as suggested in drm_drv.c. Adding drm_atomic_helper_shutdown() in ast_pci_remove to prevent leaking.

We are seeing root ports on some desktop boards support D3cold for discrete graphics card. So when efifb is in use while graphics device isn't bound to a driver, PCI and ACPI will put the graphics to D3cold when runtime suspend kicks in, makes efifb stop working. So ensure the graphics device won't be runtime suspended, to keep efifb work all the time. Signed-off-by:
