38327b6cb1 drm/amd/display: adjust MALL size available for DCN32 and DCN321
commit 235fef6c7f upstream.

[Why]
MALL size available can vary for different SKUs.
Use num_chans read from VBIOS to determine the available MALL size we can use

[How]
Define max_chans for DCN32 and DCN321.
If num_chans is max_chans, then return max_chans as we can access the
 entire MALL space.
Otherwise, define avail_chans as the number of available channels we are
 allowed instead.
Return corresponding number of channels back and use this to calculate
 available MALL size.

09fa1a6b0c drm/msm/adreno: fix runtime PM imbalance at unbind
[ Upstream commit 6153c44392 ]

A recent commit moved enabling of runtime PM from adreno_gpu_init() to
adreno_load_gpu() (called on first open()), which means that unbind()
may now be called with runtime PM disabled in case the device was never
opened in between.

Make sure to only forcibly suspend and disable runtime PM at unbind() in
case runtime PM has been enabled to prevent a disable count imbalance.

This specifically avoids leaving runtime PM disabled when the device
is later opened after a successful bind:

d1a3ca3ad4 adreno: Shutdown the GPU properly
[ Upstream commit e752e5454e ]

During kexec on ARM device, we notice that device_shutdown() only calls
pm_runtime_force_suspend() while shutting down the GPU. This means the GPU
kthread is still running and further, there maybe active submits.

This causes all kinds of issues during a kexec reboot:

It can be barely visible, but the declaration says about the parameters
in the middle:
  enum nv50_disp_interlock_type,
  u32 interlock_data,
  u32 heads,

While the definition states differently:

  enum nv50_disp_interlock_type interlock_type,
  u32 interlock_data,

Unify/fix the declaration to match the definition.

783c225e91 drm/i915: Populate encoder->devdata for DSI on icl+
[ Upstream commit 14e591a193 ]

We now have some eDP+DSI dual panel systems floating around
where the DSI panel is the secondary LFP and thus needs to
consult "panel type 2" in VBT in order to locate all the
other panel type dependant stuff correctly.

To that end we need to pass in the devdata to
intel_bios_init_panel_late(), otherwise it'll just assume
we want the primary panel type. So let's try to just populate
the vbt.ports[] stuff and encoder->devdata for icl+ DSI
panels as well.

We can't do this on older platforms as there we risk a DSI
port aliasing with a HDMI/DP port, which is a totally legal
thing as the DSI ports live in their own little parallel
universe.

bd61a84b5e drm/i915: Do panel VBT init early if the VBT declares an explicit panel type
[ Upstream commit 3f9ffce576 ]

Lots of ADL machines out there with bogus VBTs that declare
two eDP child devices. In order for those to work we need to
figure out which power sequencer to use before we try the EDID
read. So let's do the panel VBT init early if we can, falling
back to the post-EDID init otherwise.

The post-EDID init panel_type=0xff approach of assuming the
power sequencer should already be enabled doesn't really work
with multiple eDP panels, and currently we just end up using
the same power sequencer for both eDP ports, which at least
confuses the wakeref tracking, and potentially also causes us
to toggle the VDD for the panel when we should not.

e340197a45 drm/i915: Introduce intel_panel_init_alloc()
[ Upstream commit f70f8153e3 ]

Introduce a place where we can initialize connector->panel
after it's been allocated. We already have a intel_panel_init()
so had to get creative with the name and came up with
intel_panel_init_alloc().

9f6f6f42b9 drm/display: Don't block HDR_OUTPUT_METADATA on unknown EOTF
commit e5eef23e26 upstream.

The EDID of an HDR display defines EOTFs that are supported
by the display and can be set in the HDR metadata infoframe.
Userspace is expected to read the EDID and set an appropriate
HDR_OUTPUT_METADATA.

In drm_parse_hdr_metadata_block the kernel reads the supported
EOTFs from the EDID and stores them in the
drm_connector->hdr_sink_metadata. While doing so it also
filters the EOTFs to the EOTFs the kernel knows about.
When an HDR_OUTPUT_METADATA is set it then checks to
make sure the EOTF is a supported EOTF. In cases where
the kernel doesn't know about a new EOTF this check will
fail, even if the EDID advertises support.

Since it is expected that userspace reads the EDID to understand
what the display supports it doesn't make sense for DRM to block
an HDR_OUTPUT_METADATA if it contains an EOTF the kernel doesn't
understand.

This comes with the added benefit of future-proofing metadata
support. If the spec defines a new EOTF there is no need to
update DRM and an compositor can immediately make use of it.

Bug: https://gitlab.freedesktop.org/wayland/weston/-/issues/609

v2: Distinguish EOTFs defind in kernel and ones defined
    in EDID in the commit description (Pekka)

v3: Rebase; drm_hdmi_infoframe_set_hdr_metadata moved
    to drm_hdmi_helper.c

27b5871abd drm/i915: Fix system suspend without fbdev being initialized
commit 8038510b1f upstream.

If fbdev is not initialized for some reason - in practice on platforms
without display - suspending fbdev should be skipped during system

fb5f2b4265 drm/i915/dp_mst: Add the MST topology state for modesetted CRTCs
commit 326b1e792f upstream.

Add the MST topology for a CRTC to the atomic state if the driver
needs to force a modeset on the CRTC after the encoder compute config
functions are called.

Later the MST encoder's disable hook also adds the state, but that isn't
guaranteed to work (since in that hook getting the state may fail, which
can't be handled there). This should fix that, while a later patch fixes
the use of the MST state in the disable hook.

v2: Add missing forward struct declartions, caught by hdrtest.
v3: Factor out intel_dp_mst_add_topology_state_for_connector() used
    later in the patchset.

6e48e7901e drm/display/dp_mst: Fix payload addition on a disconnected sink
commit 33f960e23c upstream.

If an MST stream is enabled on a disconnected sink, the payload for the
stream is not created and the MST manager's payload count/next start VC
slot is not updated. Since the payload's start VC slot may still contain
a valid value (!= -1) the subsequent disabling of such a stream could
cause an incorrect decrease of the payload count/next start VC slot in
drm_dp_remove_payload() and hence later payload additions will fail.

Fix the above by marking the payload as invalid in the above case, so
that it's skipped during payload removal. While at it add a debug print
for this case.

f0f427f385 drm/edid: fix parsing of 3D modes from HDMI VSDB
commit 72794d16bd upstream.

Commit 537d9ed2f6 ("drm/edid: convert add_cea_modes() to use cea db
iter") inadvertently moved the do_hdmi_vsdb_modes() call within the db
iteration loop, always passing NULL as the CTA VDB to
do_hdmi_vsdb_modes(), skipping a lot of stereo modes.

Move the call back outside of the loop.

This does mean only one CTA VDB and HDMI VSDB combination will be
handled, but it's an unlikely scenario to have more than one of either
block, and it was not accounted for before the regression either.

26cbe4c63d drm/edid: fix AVI infoframe aspect ratio handling
commit 1cbc1f0d32 upstream.

We try to avoid sending VICs defined in the later specs in AVI
infoframes to sinks that conform to the earlier specs, to not upset
them, and use 0 for the VIC instead. However, we do this detection and
conversion to 0 too early, as we'll need the actual VIC to figure out
the aspect ratio.

In particular, for a mode with 64:27 aspect ratio, 0 for VIC fails the
AVI infoframe generation altogether with -EINVAL.

Separate the VIC lookup from the "filtering", and postpone the
filtering, to use the proper VIC for aspect ratio handling, and the 0
VIC for the infoframe video code as needed.

The source of this warning is in iosys_map_clear() called from
dma_buf_vmap(). It conditionally sets values based on map->is_iomem. The
iosys_map variables are allocated uninitialized on the stack leading to
->is_iomem having all kinds of values and not only 0/1.

Fix this by zeroing the iosys_map variables.

be11d0d9c4 drm/i915: Don't use BAR mappings for ring buffers with LLC
commit 85636167e3 upstream.

Direction from hardware is that ring buffers should never be mapped
via the BAR on systems with LLC. There are too many caching pitfalls
due to the way BAR accesses are routed. So it is safest to just not
use it.

8551ddbff0 drm/radeon: Fix eDP for single-display iMac11,2
commit 05eacc198c upstream.

Apple iMac11,2 (mid 2010) also with Radeon HD-4670 that has the same
issue as iMac10,1 (late 2009) where the internal eDP panel stays dark on
driver load.  This patch treats iMac11,2 the same as iMac10,1,
so the eDP panel stays active.

Additional steps:
Kernel boot parameter radeon.nomodeset=0 required to keep the eDP
panel active.

This patch is an extension of
commit 564d8a2cf3 ("drm/radeon: Fix eDP for single-display iMac10,1 (v2)")

804bdc5fe0 Revert "drm/amdgpu: TA unload messages are not actually sent to psp when amdgpu is uninstalled"
[ Upstream commit 39934d3ed5 ]

This reverts commit fac53471d0.
The following change: move the drm_dev_unplug call after
amdgpu_driver_unload_kms in amdgpu_pci_remove. The reason is
the following: amdgpu_pci_remove calls drm_dev_unregister
and it should be called first to ensure userspace can't access the
device instance anymore. If we call drm_dev_unplug after
amdgpu_driver_unload_kms then we observe IGT PCI software unplug
test failure (kernel hung) for all ASICs. This is how this
regression was found.

After this revert, the following commands do work not, but it would
be fixed in the next commit:
 - sudo modprobe -r amdgpu
 - sudo modprobe amdgpu
