drm-next
This is the 2nd pull request for the malidp-next. The new patches add
additional support for Arm Mali D71 so that it can now be enabled
correctly and brought up on any SoC that contains the IP. From now on
we will start focusing on adding writeback, scaling and other useful
features to bring the driver to the same level of maturity as mali-dp.

On a failed resume we may experience unrecoverable errors. Plumb the error code
through to actually let the driver fail. On a reverse-prime setup this helps the
drm subsystem to at least recover the integrated gpu.
This can especially happen with secboot timing out, leaving the hardware in a
non-functioning state.

For a while, we've had the problem of i2c bus access not grabbing
a runtime PM ref when it's being used in userspace by i2c-dev, resulting
in nouveau spamming the kernel log with errors if anything attempts to
access the i2c bus while the GPU is in runtime suspend. An example:
[ 130.078386] nouveau 0000:01:00.0: i2c: aux 000d: begin idle timeout ffffffff
Since the GPU is in runtime suspend, the MMIO region that the i2c bus is
on isn't accessible. On x86, the standard behavior for accessing an
unavailable MMIO region is to just return ~0.
Except, that turned out to be a lie. While computers with a clean
concious will return ~0 in this scenario, some machines will actually
completely hang a CPU on certian bad MMIO accesses. This was witnessed
with someone's Lenovo ThinkPad P50, where sensors-detect attempting to
access the i2c bus while the GPU was suspended would result in a CPU
hang:

watchdog: BUG: soft lockup - CPU#5 stuck for 23s! [sensors-detect:12438]
Yikes! While I wanted to try to make it so that accessing an i2c bus on
nouveau would wake up the GPU as needed, airlied pointed out that pretty
much any usecase for userspace accessing an i2c bus on a GPU (mainly for
the DDC brightness control that some displays have) is going to only be
useful while there's at least one display enabled on the GPU anyway, and
the GPU never sleeps while there's displays running.
Since teaching the i2c bus to wake up the GPU on userspace accesses is a
good deal more difficult than it might seem, mostly due to the fact that
we have to use the i2c bus during runtime resume of the GPU, we instead
opt for the easiest solution: don't let userspace access i2c busses on
the GPU at all while it's in runtime suspend.
Changes since v1:
* Also disable i2c busses that run over DP AUX

Pre-DCE12 needs special treatment for BTR / low framerate
compensation for more stable behaviour:
According to comments in the code and some testing on DCE-8
and DCE-11, DCE-11 and earlier only apply VTOTAL_MIN/MAX
programming with a lag of one frame, so the special BTR hw
programming for intermediate fixed duration frames must be
done inside the current frame at flip submission in atomic
commit tail, ie. one vblank earlier, and the fixed refresh
intermediate frame mode must be also terminated one vblank
earlier on pre-DCE12 display engines.
To achieve proper termination on < DCE-12 shift the point
when the switch-back from fixed vblank duration to variable
vblank duration happens from the start of VBLANK (vblank irq,
as done on DCE-12+) to back-porch or end of VBLANK (handled
by vupdate irq handler). We must leave the switch-back code
inside VBLANK irq for DCE12+, as before.
Doing this, we get much better behaviour of BTR for up-sweeps,
ie. going from short to long frame durations (~high to low fps)
and for constant framerate flips, as tested on DCE-8 and
DCE-11. Behaviour is still not quite as good as on DCN-1
though.
On down-sweeps, going from long to short frame durations
(low fps to high fps) < DCE-12 is a little bit improved,
although by far not as much as for up-sweeps and constant
fps.
v2: Fix some wrong locking, as pointed out by Nicholas.
v3: Simplify if-condition in vupdate-irq - nit by Nicholas.

[Why]
Originally we did the amdgpu_dm_handle_vrr_transition call before
interrupts were enabled. After the interrupt toggling logic was
moved around for support enabling CRTCs with no primary planes
active this was no longer being called in the case where there
wasn't a modeset.
This fixes failures in igt@kms_vrr@* with error
"Timed out: Waiting for vblank event".
[How]
Shift them back into the loop that always ran before interrupts were
enabled.
Pull out the logic that updated VRR state into the same loop since
there's no reason these need to be split.
In the case where we're going from VRR off, no planes to VRR on, some
active planes we'll still be covered for having the VRR vupdate
handler enabled - vblank will be re-enabled at this point, it will
see that VRR is active and set the vupdate interrupt on there.

[Why]
Due to the generic introduction of seamless boot, the display is no
longer blanked upon boot. However, this causes corruption on some
systems that does not lock the memory in the non-secure boot case,
resulting in brief corruption on boot due to garbage being written into
the frame buffer.
[How]
Add a flag, read during DC init, to determine whether display should be
blanked on boot. Default to true.

[Why]
Many userspace applications (and IGT) seem to expect that most drivers
can keep a CRTC active and enabled if there are no primary or overlay
planes.
DC is setup to handle this but only in the case where there are
absolutely no planes on the CRTC - no primary, cursor, or overlay.
[How]
Add a check to reject commits that have cursor planes enabled and
nothing else on CRTCs since we can't handle that. The new helper
does_crtc_have_active_cursor is used for this.
In atomic commit tail, we need to let DC know that there are zero
planes enabled when doing stream updates to let it disable and blank
pipes as appropriate.

[Why]
When disabling all the pipes for a CRTC the page-flip interrupt also
gets disabled on Raven. We can't re-enable the page-flip interrupt
unless we give DC at least one active DC plane.
We currently enable interrupts after the call to dc_commit_state since
there's currently no valid sequence that should disable all the planes
or re-enable planes for a CRTC without first going through
dc_commit_state.
If we were to allow for a CRTC to be enabled with no primary plane this
would not be the case - the call to dc_commit_updates_for_stream would
enable the planes when going from zero to at least one active plane,
but manage_dm_interrupts would have been called too early.
This results in a page-flip timeout on any subsequent commits since we
think the page-flip are now enabled when they're actually disabled.
We need to enable interrupts after the call to
dc_commit_updates_for_stream.
[How]
Split enabling interrupts into two passes. One pass before
dc_commit_updates_for_stream and one after it.
Shifting all the interrupts to be strictly below the call doesn't
currently work even though it should in theory. We end up queuing
off the vblank event to be handle by the flip handler before it's
actually enabled in some cases, particularly:
old_crtc_state->active = false -> new_crtc_state->active = true
The framebuffer states haven't changed and we can technically still
do a "pageflip" in this case and send back the event.

[Why]
We only currently drop the vblank reference when the stream is
being removed from the context. We should be dropping it whenever we
disable interrupts and reaquiring it after we re-enable them.
We also never get the extra reference correctly when re-enabling
interrupts, since grabbing the reference has the following condition:
if (!crtc_state->crc_enabled && enable)
drm_crtc_vblank_get(crtc);
This means that crc_enabled must be *false* in order to grab the extra
reference.
[How]
Always drop the ref whenever we're disabling interrupts.
Only disable CRC capture when the stream is being removed.
Always grab the ref by setting dm_new_crtc_state->crc_enabled = false
before the call to re-enable CRC capture.

[Why]
We can't do cursor programming after the planes have been disabled
since there won't be any pipes - leading to lock warnings and the wrong
cursor state being left in the registers.
When we re-enable the planes after the previous cursor state will also
remain if we don't have a cursor plane.
[How]
If we're disabling the planes then do the cursor programming first.
If we're not disabling the planes then do the cursor programming after.
Introduce the amdgpu_dm_commit_cursors helper to avoid code duplication
for both of these cases.

[Why]
The vblank and pageflip interrupts should only be enabled for a CRTC
that's enabled and has active planes.
The current logic takes care of this, but isn't setup to handle the case
where the active plane count goes to zero but the stream remains
enabled.
We currently block this case since we don't allow commits that enable a
CRTC with no active planes, but shouldn't be any reason we can't support
this from a hardware perspective and many userspace applications expect
to be able to do it (like IGT).
[How]
The count_crtc_active_planes function fills in the number of
"active_planes" on the dm_crtc_state. This should be the same as
DC's plane_count on the stream_status but easier to access since we
don't need to lock the private atomic state with the DC context.
Add the "interrupts_enabled" flag to the dm_crtc_state and set it based
on whether the stream exists and if there are active planes on the
stream.
Update the disable and enable logic to make use of this new flag.
There shouldn't be any functional change (yet) with this patch.

amdgpu_sriov_vf would return 0x0 or 0x4 to indicate if sriov.
but F32_POLL_ENABLE need 0x0 or 0x1 to determine if enabled.
set 0x4 into F32_POLL_ENABLE would make SDMA0_GFX_RB_WPTR_POLL_CNTL not working.

Currently an allocation is being made but the allocation failure
check is being performed on another pointer. Fix this by checking
the correct pointer. Also use the normal kernel idiom for null
pointer checks.
