de00d253bc drm/amd/display: link_rate_set should index into table
[Why]
Current implementation that maps link_rate_set value to
actual link rate is incorrect.

[How]
Fix this implementation, such that link_rate_set indexes into
the supported_link_rate table.

00fbeb4e2f drm/amd/display: DC VM Fixes
[Why]
VM_helper needs to be intialized with the dc struct in order to fix
an unallocated memory issue. System aperture settings should be
initialized to 0 and guarded with a check to make sure vm_config
is valid.

[How]
Allocate and free memory for vm_helper with other dc members.
Check whether the vm_config valid bit is set before initializing
aperture settings.

5062b797db drm/amd/display: Don't re-program planes for DPMS changes
[Why]
There are opt1c lock warnings and CRTC read timeouts when running the
"igt@kms_plane@plane-position-hole-dpms-pipe-*" tests. These are
caused by trying to reprogram planes that are not in the current
context.

DPMS off removes the stream from the context. In this case:

new_crtc_state->active_changed = true
new_crtc_state->mode_changed = false

The planes are reprogrammed before the stream is removed from the
context because stream_state->mode_changed = false.

For DPMS adds the stream and planes back to the context:

new_crtc_state->active_changed = true
new_crtc_state->mode_changed = false

The planes are also reprogrammed here before the stream is added to the
context because stream_state->mode_changed = true. They were not
previously in the current context so warnings occur here.

[How]
Set stream_state->mode_changed = true when
new_crtc_state->active_changed = true too.

This prevents reprogramming before the context is applied in DC. The
programming will be done after the context is applied.

6297388e1e drm/omap: dsi: Hack-fix DSI bus flags
Since commit b4935e3a3cfa ("drm/omap: Store bus flags in the
omap_dss_device structure") video mode flags are managed by the omapdss
(and later omapdrm) core based on bus flags stored in omap_dss_device.
This works fine for all devices whose video modes are set by the omapdss
and omapdrm core, but breaks DSI operation as the DSI still uses legacy
code paths and sets the DISPC timings manually.

To fix the problem properly we should move the DSI encoder to the new
encoder model. This will however require a considerable amount of work.
Restore DSI operation by adding back video mode flags handling in the
DSI encoder driver as a hack in the meantime.

d028a646e8 drm/i915: Try to sanitize bogus DPLL state left over by broken SNB BIOSen
Certain SNB machines (eg. ASUS K53SV) seem to have a broken BIOS
which misprograms the hardware badly when encountering a suitably
high resolution display. The programmed pipe timings are somewhat
bonkers and the DPLL is totally misprogrammed (P divider == 0).
That will result in atomic commit timeouts as apparently the pipe
is sufficiently stuck to not signal vblank interrupts.

IIRC something like this was also observed on some other SNB
machine years ago (might have been a Dell XPS 8300) but a BIOS
update cured it. Sadly looks like this was never fixed for the
ASUS K53SV as the latest BIOS (K53SV.320 11/11/2011) is still
broken.

The quickest way to deal with this seems to be to shut down
the pipe+ports+DPLL. Unfortunately doing this during the
normal sanitization phase isn't quite soon enough as we
already spew several WARNs about the bogus hardware state.
But it's better than hanging the boot for a few dozen seconds.
Since this is limited to a few old machines it doesn't seem
entirely worthwile to try and rework the readout+sanitization
code to handle it more gracefully.

77476360f1 drm/amd/display: Disconnect mpcc when changing tg
[Why]
This fixes an mpc programming error for the following sequence of
atomic commits when pipe split is enabled:

Commit 1: CRTC0 (plane 4, plane 3)

Pipe 0: old_plane_state = A0, new_plane_state = A1,   new_tg = T0
Pipe 1: old_plane_state = B0, new_plane_state = B1,   new_tg = T0
Pipe 2: old_plane_state = A0, new_plane_state = A1,   new_tg = T0
Pipe 3: old_plane_state = B0, new_plane_state = B1,   new_tg = T0

Commit 2: CRTC0 (plane 3), CRTC1 (plane 2)

Pipe 0: old_plane_state = A1, new_plane_state = A2,   new_tg = T0
Pipe 1: old_plane_state = B1, new_plane_state = B2,   new_tg = T1
Pipe 2: old_plane_state = A1, new_plane_state = NULL, new_tg = NULL
Pipe 3: old_plane_state = B1, new_plane_state = NULL, new_tg = NULL

In the second commit the assertion for mpcc in use is hit because
mpcc disconnect never occurs for pipe 1. This is because the stream
changes for pipe 1 and the opp_list is empty.

This sequence occurs when running the
"igt@kms_plane_multiple@atomic-pipe-A-tiling-none" test with two
displays connected.

[How]
Expand the reset condition to include:

"old_pipe_ctx->stream_res.tg != new_pipe_ctx->stream_res.tg"

...but only when the plane state is non-NULL for both old and new.

plane, so the check needed to be updated.

The acrtc->stream state doesn't need to be checked for NULL before
updating FreeSync either since there needs to be a stream to be
inside this function as a prerequisite.

f3e3698d05 drm/amd/display: Apply all surface updates onto surfaces
[Why]
Most surface updates weren't propagated onto the surface during
dc_commit_updates_for_stream. This makes it more difficult for DC to
determine the actual surface update type required.

[How]
Use copy_surface_update_to_plane to propagate the changes. The FreeSync
surface timing information update for BTR has been moved out of
amdgpu_dm.c into this function as well.

[Why]
"IRQ_HPD Pulse Length Test" DP compliance test
fails. Test complains that certain DPCD registers
are not read within 100 ms.

[How]
msleep is inaccurate for small values. Used udelay
instead for accuracy.

12a8bd8862 drm/amd/display: Use context parameters to enable FBC
[What]
FBC fails to get enabled when switched between LINEAR(console/VT)
and non-LINEAR(GUI) based rendering due to default value of
tiling info stored in the current_state which is used for deciding
whether or not to turn FBC on or off.

[How]
Use context structure's tiling information which is coherant with
the screen updates.

[Why]
When CONFIG_DEBUG_FS isn't defined then amdgpu_dm_crtc_set_crc_source

Guard the call based on CONFIG_DEBUG_FS - CRC capture isn't supported

88ec89adec drm/nouveau: Move PBN and VCPI allocation into nv50_head_atom
Atomic checks should never modify anything outside of the state that
they're passed in. Unfortunately this appears to be exactly what we're
doing in nv50_msto_atomic_check() where we update mstc->pbn every time
the function is called. This hasn't caused any bugs yet, but it needs to
be fixed in order to ensure that when committing an artificially
duplicated state (like during system resume), that we reuse the PBN of
that state to perform VCPI allocations and don't recalculate a different
value from the drm connector's reported bpc.

Also, move the VCPI slot allocations while we're at it as well. With
this, removing a topology in suspend while using nouveau no longer
causes the new atomic VCPI helpers to complain.

022debad06 drm/atomic: Add drm_atomic_state->duplicated
Since

commit 39b50c603878 ("drm/atomic_helper: Stop modesets on unregistered
connectors harder")

We've been failing atomic checks if they try to enable new displays on
unregistered connectors. This is fine except for the one situation that
breaks atomic assumptions: suspend/resume. If a connector is
unregistered before we attempt to restore the atomic state, something we
end up failing the atomic check that happens when trying to restore the
state during resume.

Normally this would be OK: we try our best to make sure that the atomic
state pre-suspend can be restored post-suspend, but failures at that
point usually don't cause problems. That is of course, until we
introduced the new atomic MST VCPI helpers:

This appears to be happening because we destroy the VCPI allocations
when disabling all connected displays while suspending, and those VCPI
allocations don't get restored on resume due to failing to restore the
atomic state.

So, fix this by introducing the suspending option to
drm_atomic_helper_duplicate_state() and use that to indicate in the
atomic state that it's being used for suspending or resuming the system,
and thus needs to be fixed up by the driver. We can then use the new
state->duplicated hook to tell update_connector_routing() in
drm_atomic_check_modeset() to allow for modesets on unregistered
connectors, which allows us to restore atomic states that contain MST
topologies that were removed after the state was duplicated and thus:
mostly fixing suspend and resume. This just leaves some issues that were
introduced with nouveau, that will be addressed next.

Changes since v3:
* Remove ->duplicated hunks that I left in the VCPI helpers by accident.
  These don't need to be here, that was the supposed to be the purpose
  of the last revision
Changes since v2:
* Remove the changes in this patch to the VCPI helpers, they aren't
  needed anymore
Changes since v1:
* Rename suspend_or_resume to duplicated
