dma-buf/sw_sync: clean up list before signaling the fence
If userspace already dropped its own reference by closing the sw_sync
fence fd we might end up in a deadlock where
dma_fence_is_signaled_locked() will trigger the release of the fence and
thus try to hold the lock to remove the fence from the list.
dma_fence_is_signaled_locked() tries to release/free the fence and hold
the lock in the process.
We fix that by changing the order operation and clean up the list and
rb-tree first.

dma-buf/sync_file: Allow multiple sync_files to wrap a single dma-fence
Up until recently sync_file were create to export a single dma-fence to
userspace, and so we could canabalise a bit insie dma-fence to mark
whether or not we had enable polling for the sync_file itself. However,
with the advent of syncobj, we do allow userspace to create multiple
sync_files for a single dma-fence. (Similarly, that the sw-sync
validation framework also started returning multiple sync-files wrapping
a single dma-fence for a syncpt also triggering the problem.)

single bit in the shared dma-fence and restores the sync_file->flags for

drm/vc4: Add an ioctl for labeling GEM BOs for summary stats
This has proven immensely useful for debugging memory leaks and
overallocation (which is a rather serious concern on the platform,
given that we typically run at about 256MB of CMA out of up to 1GB
total memory, with framebuffers that are about 8MB ecah).
The state of the art without this is to dump debug logs from every GL
application, guess as to kernel allocations based on bo_stats, and try
to merge that all together into a global picture of memory allocation
state. With this, you can add a couple of calls to the debug build of
the 3D driver and get a pretty detailed view of GPU memory usage from
/debug/dri/0/bo_stats (or when we debug print to dmesg on allocation
failure).
The Mesa side currently labels at the gallium resource level (so you
see that a 1920x20 pixmap has been created, presumably for the window
system panel), but we could extend that to be even more useful with
glObjectLabel() names being sent all the way down to the kernel.
(partial) example of sorted debugfs output with Mesa labeling all
resources:
kernel BO cache: 16392kb BOs (3)
tiling shadow 1920x1080: 8160kb BOs (1)
resource 1920x1080@32/0: 8160kb BOs (1)
scanout resource 1920x1080@32/0: 8100kb BOs (1)
kernel: 8100kb BOs (1)
v2: Use strndup_user(), use lockdep assertion instead of just a
comment, fix an array[-1] reference, extend comment about name
freeing.

drm/hisilicon: fix build error without fbdev emulation
We cannot reference priv->fbdev outside of the #ifdef:

The current drm_atomic_helper_commit_tail helper works only if the CRTC is

That implementation is then duplicated by some drivers. Instead of
documenting it, let's implement an helper that all the relevant users can

drm/fb-helper: Support deferred setup
FB helper code falls back to a 1024x768 mode if no outputs are connected
or don't report back any modes upon initialization. This can be annoying
because outputs that are added to FB helper later on can't be used with
FB helper if they don't support a matching mode.
The fallback is in place because VGA connectors can happen to report an
unknown connection status even when they are in fact connected.
Some drivers have custom solutions in place to defer FB helper setup
until at least one output is connected. But the logic behind these
solutions is always the same and there is nothing driver-specific about
it, so a better alterative is to fix the FB helper core and add support
for all drivers automatically.
This patch adds support for deferred FB helper setup. It checks all the
connectors for their connection status, and if all of them report to be
disconnected marks the FB helper as needing deferred setup. Whet setup
is deferred, the FB helper core will automatically retry setup after a
hotplug event, and it will keep trying until it succeeds.
v2: Rebase onto my entirely reworked fbdev helper locking. One big
difference is that this version again drops&reacquires the fbdev lock
(which is now fb_helper->lock, but before this patch series it was
mode_config->mutex), because register_framebuffer must be able to
recurse back into fbdev helper code for the initial screen setup.
v3: __drm_fb_helper_initial_config must hold fb_helper->lock upon
return, I've fumbled that in the deferred setup case (Liviu).
v4: I was blind, redo this all. __drm_fb_helper_initial_config
shouldn't need to reacquire fb_helper->lock, that just confuses
callers. I myself got confused by kernel_fb_helper_lock and somehow
thought it's the same as fb_helper->lock. Tsk.
Also simplify the logic a bit (we don't need two functions to probe
connectors), we can stick much closer to the existing code. And update
some comments I've spotted that are outdated.
v5: Don't pass -EAGAIN to drivers, it's just an internal error code
(Liviu).
v6: Add _and_unlock suffix to clarify locking (Maarten)
