Merge tag 'drm-misc-next-2019-08-19' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for 5.4:

UAPI Changes:

Cross-subsystem Changes:

Core Changes:
  - dma-buf: add reservation_object_fences helper, relax
             reservation_object_add_shared_fence, remove
             reservation_object seq number (and then
             restored)
  - dma-fence: Shrinkage of the dma_fence structure,
               Merge dma_fence_signal and dma_fence_signal_locked,
               Store the timestamp in struct dma_fence in a union with
               cb_list

Driver Changes:
  - More dt-bindings YAML conversions
  - More removal of drmP.h includes
  - dw-hdmi: Support get_eld and various i2s improvements
  - gm12u320: Few fixes
  - meson: Global cleanup
  - panfrost: Few refactors, Support for GPU heap allocations
  - sun4i: Support for DDC enable GPIO
  - New panels: TI nspire, NEC NL8048HL11, LG Philips LB035Q02,
                Sharp LS037V7DW01, Sony ACX565AKM, Toppoly TD028TTEC1
                Toppoly TD043MTEA1

 /**
  * DOC: Overview
  *
- * DRM synchronisation objects (syncobj, see struct &drm_syncobj) are
- * persistent objects that contain an optional fence. The fence can be updated
- * with a new fence, or be NULL.
+ * DRM synchronisation objects (syncobj, see struct &drm_syncobj) provide a
+ * container for a synchronization primitive which can be used by userspace
+ * to explicitly synchronize GPU commands, can be shared between userspace
+ * processes, and can be shared between different DRM drivers.
+ * Their primary use-case is to implement Vulkan fences and semaphores.
+ * The syncobj userspace API provides ioctls for several operations:
  *
- * syncobj's can be waited upon, where it will wait for the underlying
- * fence.
+ *  - Creation and destruction of syncobjs
+ *  - Import and export of syncobjs to/from a syncobj file descriptor
+ *  - Import and export a syncobj's underlying fence to/from a sync file
+ *  - Reset a syncobj (set its fence to NULL)
+ *  - Signal a syncobj (set a trivially signaled fence)
+ *  - Wait for a syncobj's fence to appear and be signaled
  *
- * syncobj's can be export to fd's and back, these fd's are opaque and
- * have no other use case, except passing the syncobj between processes.
+ * At it's core, a syncobj is simply a wrapper around a pointer to a struct
+ * &dma_fence which may be NULL.
+ * When a syncobj is first created, its pointer is either NULL or a pointer
+ * to an already signaled fence depending on whether the
+ * &DRM_SYNCOBJ_CREATE_SIGNALED flag is passed to
+ * &DRM_IOCTL_SYNCOBJ_CREATE.
+ * When GPU work which signals a syncobj is enqueued in a DRM driver,
+ * the syncobj fence is replaced with a fence which will be signaled by the
+ * completion of that work.
+ * When GPU work which waits on a syncobj is enqueued in a DRM driver, the
+ * driver retrieves syncobj's current fence at the time the work is enqueued
+ * waits on that fence before submitting the work to hardware.
+ * If the syncobj's fence is NULL, the enqueue operation is expected to fail.
+ * All manipulation of the syncobjs's fence happens in terms of the current
+ * fence at the time the ioctl is called by userspace regardless of whether
+ * that operation is an immediate host-side operation (signal or reset) or
+ * or an operation which is enqueued in some driver queue.
+ * &DRM_IOCTL_SYNCOBJ_RESET and &DRM_IOCTL_SYNCOBJ_SIGNAL can be used to
+ * manipulate a syncobj from the host by resetting its pointer to NULL or
+ * setting its pointer to a fence which is already signaled.
  *
- * Their primary use-case is to implement Vulkan fences and semaphores.
  *
- * syncobj have a kref reference count, but also have an optional file.
- * The file is only created once the syncobj is exported.
- * The file takes a reference on the kref.
+ * Host-side wait on syncobjs
+ * --------------------------
+ *
+ * &DRM_IOCTL_SYNCOBJ_WAIT takes an array of syncobj handles and does a
+ * host-side wait on all of the syncobj fences simultaneously.
+ * If &DRM_SYNCOBJ_WAIT_FLAGS_WAIT_ALL is set, the wait ioctl will wait on
+ * all of the syncobj fences to be signaled before it returns.
+ * Otherwise, it returns once at least one syncobj fence has been signaled
+ * and the index of a signaled fence is written back to the client.
+ *
+ * Unlike the enqueued GPU work dependencies which fail if they see a NULL
+ * fence in a syncobj, if &DRM_SYNCOBJ_WAIT_FLAGS_WAIT_FOR_SUBMIT is set,
+ * the host-side wait will first wait for the syncobj to receive a non-NULL
+ * fence and then wait on that fence.
+ * If &DRM_SYNCOBJ_WAIT_FLAGS_WAIT_FOR_SUBMIT is not set and any one of the
+ * syncobjs in the array has a NULL fence, -EINVAL will be returned.
+ * Assuming the syncobj starts off with a NULL fence, this allows a client
+ * to do a host wait in one thread (or process) which waits on GPU work
+ * submitted in another thread (or process) without having to manually
+ * synchronize between the two.
+ * This requirement is inherited from the Vulkan fence API.
+ *
+ *
+ * Import/export of syncobjs
+ * -------------------------
+ *
+ * &DRM_IOCTL_SYNCOBJ_FD_TO_HANDLE and &DRM_IOCTL_SYNCOBJ_HANDLE_TO_FD
+ * provide two mechanisms for import/export of syncobjs.
+ *
+ * The first lets the client import or export an entire syncobj to a file
+ * descriptor.
+ * These fd's are opaque and have no other use case, except passing the
+ * syncobj between processes.
+ * All exported file descriptors and any syncobj handles created as a
+ * result of importing those file descriptors own a reference to the
+ * same underlying struct &drm_syncobj and the syncobj can be used
+ * persistently across all the processes with which it is shared.
+ * The syncobj is freed only once the last reference is dropped.
+ * Unlike dma-buf, importing a syncobj creates a new handle (with its own
+ * reference) for every import instead of de-duplicating.
+ * The primary use-case of this persistent import/export is for shared
+ * Vulkan fences and semaphores.
+ *
+ * The second import/export mechanism, which is indicated by
+ * &DRM_SYNCOBJ_FD_TO_HANDLE_FLAGS_IMPORT_SYNC_FILE or
+ * &DRM_SYNCOBJ_HANDLE_TO_FD_FLAGS_EXPORT_SYNC_FILE lets the client
+ * import/export the syncobj's current fence from/to a &sync_file.
+ * When a syncobj is exported to a sync file, that sync file wraps the
+ * sycnobj's fence at the time of export and any later signal or reset
+ * operations on the syncobj will not affect the exported sync file.
+ * When a sync file is imported into a syncobj, the syncobj's fence is set
+ * to the fence wrapped by that sync file.
+ * Because sync files are immutable, resetting or signaling the syncobj
+ * will not affect any sync files whose fences have been imported into the
+ * syncobj.

   - Bifrost specific feature and issue handling

-
 - Per FD address space support. The h/w supports multiple addresses spaces.
   The hard part is handling when more address spaces are needed than what
   the h/w provides.
 
-- Support pinning pages on demand (GPU page faults).
-
 - Support userspace controlled GPU virtual addresses. Needed for Vulkan. (Tomeu)
 
-- Support for madvise and a shrinker.
-
 - Compute job support. So called 'compute only' jobs need to be plumbed up to
   userspace.
