15516bf9ab drm/nouveau/mmu: qualify vmm during dtor
If the BAR initialization failed it may leave the vmm structure in an
unitialized state, leading to a null-pointer-dereference when the vmm is
dereferenced during teardown.

b3198c38f0 drm/atomic-helper: Bump vblank timeout to 100 ms
The 50 ms default timeout waiting for vblanks is too small
for the first vblank from the ST-Ericsson MCDE display
controller over DSI. Presumably this is because the DSI
display is command-mode only and the state machine will
take some time setting up its state for the first display
update, and we hit a timeout. 100 ms makes it pass without
problems.

09aef2c48e drm/amd/display: Compensate for pre-DCE12 BTR-VRR hw limitations. (v3)
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.

057be08660 drm/amd/display: Do VRR transition before enable_crc_interrupts
[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.

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.

bc92c06525 drm/amd/display: Allow commits with no planes active
[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.

b5e83f6fe1 drm/amd/display: Split enabling CRTC interrupts into two passes
[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.

e39575b9c3 drm/amd/display: Fix CRC vblank refs when changing interrupts
[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.

8ad278062d drm/amd/display: Disable cursors before disabling planes
[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.

d6ef9b4175 drm/amd/display: Refactor CRTC interrupt toggling logic
[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.

11bb22ee77 drm/komeda: Add komeda_build_layer_data_flow
build_layer_data_flow builds a input pipeline according to plane_state.
and in this initial stage only added this simplest pipeline usage:
  Layer -> compiz
The scaler and layer_split will be added in the future.

v2:
- Rebase.
- Introduce struct komeda_data_flow_cfg
- Add a function komeda_component_validate_private to replace the MACRO
  component_validate_private

43068cb7ba drm: prefix header search paths with $(srctree)/
Currently, the Kbuild core manipulates header search paths in a crazy
way [1].

To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.

Having whitespaces after -I does not matter since commit 48f6e3cf5b
("kbuild: do not drop -I without parameter").

7d26097b4b drm/atomic: Create __drm_atomic_helper_crtc_reset() for subclassing crtc_state.
We already have __drm_atomic_helper_connector_reset() and
__drm_atomic_helper_plane_reset(), extend this to crtc as well.

This will allow us to set default values in the crtc_state, without
having to do it in each driver separately.

Of all drivers that need conversion, only nouveau is done in this
commit, because it wrote its own __drm_atomic_helper_crtc_reset(),
clashing with the drm core.

b8c7d7bc83 drm/atomic: -EACCESS for lease-denied crtc lookup
With the previous patch drm_crtc_find will return NULL when the crtc
isn't in our lease, which will then disable the plane/connector. No
longer an issue since the lessor can't escape their lease terms
anymore, but not quite great semantics yet either.

Catch this and return -EACCES, so that at least evil test cases have a
better chance of making sure the kernel works correctly.

If userspace doesn't enable universal planes, then we automatically
add the primary and cursor planes. But for universal userspace there's
no such check (and maybe we only want to give the lessee one plane,
maybe not even the primary one), hence we need to check for the
implied plane.

Fix the order of lane, port parameters passed to the register macro.

Note that this was already partly fixed by commit

While at it simplify things by using the macro directly instead of an
unnecessary redirection via an array.

There was a nouveau DDX that relied on legacy context ioctls to work,

option to break the uAPI and close the mess of holes that legacy
context support is.

    drm: Turn off Legacy Context Functions

    The context functions are not used by the i915 driver and should not
    be used by modeset drivers. These driver functions contain several bugs
    and security holes. This change makes these functions optional can be
    turned on by a setting, they are turned off by default for modeset
    driver with the exception of the nouvea driver that may require them with
    an old version of libdrm.

    The previous attempt was

70b5f09e43 Merge tag 'drm-msm-next-2019-04-21' of https://gitlab.freedesktop.org/drm/msm into drm-next
This time around it is a bunch of cleanup and fixes, expanding gpu
"zap" shader support (so we can take the GPU out of secure mode on
boot) to a6xx, and small UABI extension to support robustness (see
mesa MR 673).

a9a3c0da14 drm/amd/display: add explicit handshake between x86 and DMCU
[why]
When DMCU interrupts x86, it leads to undefined phy programming

[how]
expand dmcu interface to support new PHY lock and unlock commands
if DMCU FW doesn't support these commands, they fail silently so its okay

cc602e2b0d drm/amd/display: Allow cursor position when plane_res.ipp is NULL
[Why]
Starting with DCN1, the input_pixel_processor (ipp) struct has been
replaced by dpp struct (part of DAL3.1 SW architecture change).
Need to update logic to handle cases where ipp is never allocated.

[How]
Only skip cursor position programming if both ipp and dpp resources
are NULL.
