2021-02-25drm/arc: Inline remaining filesDaniel Vetter
At less than 500 lines total feels like the right thing to do. Also noticed that the simple wrapper around drm_connector_cleanup can be dropped.

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.

2021-02-25drm/shmem-helpers: vunmap: Don't put pages for dma-bufNoralf Trønnes
dma-buf importing was reworked in commit 7d2cd72a9aa3 ("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.

2021-02-25drm/todo: Remove the drm_atomic_state todo itemMaxime Ripard
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.

2021-02-24drm/atmel-hlcdc: Rename custom plane state variableMaxime Ripard
Subsequent reworks will pass the global atomic state in the function prototype, and atomic_check and atomic_update already have such a variable already. Let's change them to ease the rework.

2021-02-24drm: Rename plane atomic_check state namesMaxime Ripard
Most drivers call the argument to the plane atomic_check hook simply state, which is going to conflict with the global atomic state in a later rework.

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.

2021-02-23drm/komeda: Annotate dma-fence critical section in commit pathDaniel Vetter
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: Daniel Vetter <daniel.vetter@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210121152959.1725404-5-daniel.vetter@ffwll.ch

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.

2021-02-19drm/qxl: fix prime vmapGerd Hoffmann
Use the correct vmap variant. We don't have a reservation here, so we can't use the _locked version. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Link: http://patchwork.freedesktop.org/patch/msgid/20210217123213.2199186-8-kraxel@redhat.com
2021-02-19drm/qxl: add qxl_bo_vmap/qxl_bo_vunmapGerd Hoffmann
Add vmap/vunmap variants which reserve (and pin) the bo. They can be used in case the caller doesn't hold a reservation for the bo.

2021-02-19drm/qxl: rename qxl_bo_kmap -> qxl_bo_vmap_lockedGerd Hoffmann
Append _locked to Make clear that these functions should be called with reserved bo's only. While being at it also rename kmap -> vmap. No functional change.

2021-02-19drm/qxl: fix lockdep issue in qxl_alloc_release_reservedGerd Hoffmann
Call qxl_bo_unpin (which does a reservation) without holding the release_mutex lock. Fixes lockdep (correctly) warning on a possible deadlock.

2021-02-19drm/qxl: use ttm bo prioritiesGerd Hoffmann
Allow to set priorities for buffer objects. Use priority 1 for surface and cursor command releases. Use priority 0 for drawing command releases. That way the short-living drawing commands are first in line when it comes to eviction, making it *much* less likely that ttm_bo_mem_force_space() picks something which can't be evicted and throws an error after waiting a while without success.

2021-02-19drm/qxl: more fence wait reworkGerd Hoffmann
Move qxl_io_notify_oom() call into wait condition. That way the driver will call it again if one call wasn't enough. Also allows to remove the extra dma_fence_is_signaled() check and the goto.
