Now that we have the DT validation in place, let's convert the device tree bindings for the Amlogic Display Controller over to YAML schemas. The original example has a leftover "dmc" memory cell, that has been removed in the yaml rewrite. The port connection table has been dropped in favor of a description of each port. Signed-off-by:

Now that we have the DT validation in place, let's convert the device tree bindings for the Amlogic Synopsys DW-HDMI specifics over to YAML schemas. The original example and usage of clock-names uses a reversed "isfr" and "iahb" clock-names, the rewritten YAML bindings uses the reversed instead of fixing the device trees order. The #sound-dai-cells optional property has been added to match this node as a sound dai. The port connection table has been dropped in favor of a description of each port. Reviewed-by:

The only remaining use for this is to protect against setting a new exclusive fence while we grab both exclusive and shared. That can also be archived by looking if the exclusive fence has changed or not after completing the operation. v2: switch setting excl fence to rcu_assign_pointer Signed-off-by:

During release of the syncpt, we remove it from the list of syncpt and the tree, but only if it is not already been removed. However, during signaling, we first remove the syncpt from the list. So, if we concurrently free and signal the syncpt, the free may decide that it is not part of the tree and immediately free itself -- meanwhile the signaler goes on to use the now freed datastructure. In particular, we get struck by commit 0e2f733a ("dma-buf: make dma_fence structure a bit smaller v2") as the cb_list is immediately clobbered by the kfree_rcu. v2: Avoid calling into timeline_fence_release() from under the spinlock Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=111381 Fixes: d3862e44 ("dma-buf/sw-sync: Fix locking around sync_timeline lists") References: 0e2f733a ("dma-buf: make dma_fence structure a bit smaller v2") Signed-off-by:

The midgard/bifrost GPUs need to allocate GPU heap memory which is allocated on GPU page faults and not pinned in memory. The vendor driver calls this functionality GROW_ON_GPF. This implementation assumes that BOs allocated with the PANFROST_BO_NOEXEC flag are never mmapped or exported. Both of those may actually work, but I'm unsure if there's some interaction there. It would cause the whole object to be pinned in memory which would defeat the point of this. On faults, we map in 2MB at a time in order to utilize huge pages (if enabled). Currently, once we've mapped pages in, they are only unmapped if the BO is freed. Once we add shrinker support, we can unmap pages with the shrinker.

In preparation to handle mapping of page faults, we need the MMU handler to be threaded as code paths take a mutex. As the IRQ may be shared, we can't use the default handler and must disable the MMU interrupts locally.

Runtime PM resume and job timeouts both call the same sequence of functions, so consolidate them to a common function. This will make changing the reset related code easier. The MMU also needs some re-initialization on reset, so rework its call. In the process, we hide the address space details within the MMU code in preparation to support multiple address spaces.

Executable buffers have an alignment restriction that they can't cross 16MB boundary as the GPU program counter is 24-bits. This restriction is currently not handled and we just get lucky. As current userspace assumes all BOs are executable, that has to remain the default. So add a new PANFROST_BO_NOEXEC flag to allow userspace to indicate which BOs are not executable. There is also a restriction that executable buffers cannot start or end on a 4GB boundary. This is mostly avoided as there is only 4GB of space currently and the beginning is already blocked out for NULL ptr detection. Add support to handle this restriction fully regardless of the current constraints. For existing userspace, all created BOs remain executable, but the GPU VA alignment will be increased to the size of the BO. This shouldn't matter as there is plenty of GPU VA space.

Setting the GPU VA when creating the GEM object doesn't allow for any conditional adjustments to the mapping. In preparation to support adjusting the mapping and per FD address spaces, restructure the GEM object creation to map and unmap the GEM object in the GEM object .open() and .close() hooks. While panfrost_gem_free_object() and panfrost_gem_prime_import_sg_table() are not really needed after this commit, keep them as we'll need them in subsequent commits.

If a driver does its own management of pages, the shmem helper object's pages array could be allocated when a SG table is not. There's not really any good reason to tie putting pages with having a SG table when freeing the object, so just put pages if the pages array is populated.

Panfrost has a need for pages allocated on demand via GPU page faults. When releasing the pages, the only thing preventing using drm_gem_put_pages() is needing to skip over unpopulated pages, so allow for skipping over NULL struct page pointers.

I made the condition of the wait_event_timeout call in gm12u320_fb_update_work a helper which takes a mutex to make sure that any writes to fb_update.run or fb_update.fb from other CPU cores are seen before the check is done. This is not necessary as the wait_event helpers contain the necessary barriers for this themselves. More over it is harmfull since by the time the check is done the task is no longer in the TASK_RUNNING state and calling mutex_lock while not in task-running is not allowed, leading to this warning when the kernel is build with some extra locking checks enabled: [11947.450011] do not call blocking ops when !TASK_RUNNING; state=2 set at [<00000000e4306de6>] prepare_to_wait_event+0x61/0x190 This commit fixes this by dropping the helper and simply directly checking the condition (without unnecessary locking) in the wait_event_timeout call.
