drm/amdgpu: Switch to drm_vblank_on/off (v2)

Equivalent change to the radeon driver.

Note that with radeon this caught a bug in the dri3 DDX
implementation, which asked for vblank interrupts when the pipe is
off. That bug needs to be fixed before we can merge this patch (if
amdgpu is affected too). Michel discovered this one.

drm/radeon: Switch to drm_vblank_on/off

These should be functionally equivalent to the older per/post modeset
functions, except that they block out drm_vblank_get right away.
There's only the clock adjusting code (outside of pageflips) in
readone which uses drm_vblank_get. But that code doesn't synchronize
against concurrent modesets and instead handles any such races by
waiting for the right vblank to arrive with a short timetout.

The longer-term plan here is to switch all kms drivers to
drm_vblank_on/off so that common code like pending event cleanup can
be done there, while drm_vblank_pre/post_modeset will be purely
drm internal for the old UMS ioctl.

Note that with this patch Michel uncovered a bug in the dri3
implementation of the DDX (it does vblank waits when the pipe is off),
which had to be fixed first.

drm/vc4: Make the CRTCs cooperate on allocating display lists.

So far, we've only ever lit up one CRTC, so this has been fine.  To
extend to more displays or more planes, we need to make sure we don't
run our display lists into each other.

Signed-off-by: Eric Anholt <eric@anholt.net>

drm/vc4: Add a proper short-circut path for legacy cursor updates.

Previously, on every modeset we would allocate new display list
memory, recompute changed planes, write all of them to the new memory,
and pointed scanout at the new list (which will latch approximately at
the next line of scanout).  We let
drm_atomic_helper_wait_for_vblanks() decide whether we needed to wait
for a vblank after a modeset before cleaning up the old state and
letting the next modeset proceed, and on legacy cursor updates we
wouldn't wait.  If you moved the cursor fast enough, we could
potentially wrap around the display list memory area and overwrite the
existing display list while it was still being scanned out, resulting
in the HVS scanning out garbage or just halting.

Instead of making cursor updates wait for scanout to move to the new
display list area (which introduces significant cursor lag in X), we
just rewrite our current display list.

drm/i915: Set aux.dev to the drm_connector device, instead of drm_device.

So far, the i915 driver and some other drivers set it to the drm_device,
which doesn't allow one to know which DP a given aux channel is related
to. Changing this to be the drm_connector provides proper nesting, still
allowing one to get the drm_device from it. Some drivers already set it
to the drm_connector.

This also removes the need to add a sysfs link for the i2c device under
the connector, as it will already be there.

v9:
 - As a side effect, drm_dp_aux_unregister() must be called before
 intel_connector_unregister(), as both the aux.dev and the i2c adapter
 dev are children of the drm_connector device now. Calling
 drm_dp_aux_unregister() before prevents them from being destroyed
 twice.

v10:
 - move aux_fini() to connector_unregister(), instead of moving
 drm_dp_aux_unregister() outside of connector_register().

dma-buf: Add ioctls to allow userspace to flush

The userspace might need some sort of cache coherency management e.g. when CPU
and GPU domains are being accessed through dma-buf at the same time. To
circumvent this problem there are begin/end coherency markers, that forward
directly to existing dma-buf device drivers vfunc hooks. Userspace can make use
of those markers through the DMA_BUF_IOCTL_SYNC ioctl. The sequence would be
used like following:
     - mmap dma-buf fd
     - for each drawing/upload cycle in CPU 1. SYNC_START ioctl, 2. read/write
       to mmap area 3. SYNC_END ioctl. This can be repeated as often as you
       want (with the new data being consumed by the GPU or say scanout device)
     - munmap once you don't need the buffer any more

v2 (Tiago): Fix header file type names (u64 -> __u64)
v3 (Tiago): Add documentation. Use enum dma_buf_sync_flags to the begin/end
dma-buf functions. Check for overflows in start/length.
v4 (Tiago): use 2d regions for sync.
v5 (Tiago): forget about 2d regions (v4); use _IOW in DMA_BUF_IOCTL_SYNC and
remove range information from struct dma_buf_sync.
v6 (Tiago): use __u64 structured padded flags instead enum. Adjust
documentation about the recommendation on using sync ioctls.
v7 (Tiago): Alex' nit on flags definition and being even more wording in the
doc about sync usage.
v9 (Tiago): remove useless is_dma_buf_file check. Fix sync.flags conditionals
and its mask order check. Add <linux/types.h> include in dma-buf.h.
