We should advertise the reworked fifo/cmd handling and huge pages support. Also while bumping the version number lets cleanup the logging, there's no point in logging whether we're atomic (we always are) or what repo we use (it's always in kernel now). Signed-off-by:

Some of them have gaps, or fields we don't clear. Native ioctl code does full copies plus zero-extends on size mismatch, so nothing can leak. But compat is more hand-rolled so need to be careful. None of these matter for performance, so just memset. Also I didn't fix up the CONFIG_DRM_LEGACY or CONFIG_DRM_AGP ioctl, those are security holes anyway. Acked-by:

By default dma_buf_export() sets the exporter name to be KBUILD_MODNAME. Unfortunately this may not be identical to the string used as the heap name (ie: "system" vs "system_heap"). This can cause some minor confusion with tooling, and there is the future potential where multiple heap types may be exported by the same module (but would all have the same name). So to avoid all this, set the exporter exp_name to the heap name.

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.

The former is the pattern that was done at first, before switching to the latter for new hooks or when it was needed. Let's start convert all the remaining helpers to provide a consistent interface, starting with the planes atomic_async_check and atomic_async_update.

[Why & How] According to DP spec, broadcast message LCT equals to 1 and LCR equals to 6. Current implementation is incorrect. Fix it. In addition, revise a bit the hdr->rad handling to include broadcast case. Signed-off-by:

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:
