commit 973a9c810c785ac270a6d50d8cf862b0c1643a10 upstream.

The YCC conversion matrix for RGB -&gt; COLOR_SPACE_YCBCR2020_TYPE is
missing the values for the fourth column of the matrix.

The fourth column of the matrix is essentially just a value that is
added given that the color is 3 components in size.
These values are needed to bias the chroma from the [-1, 1] -&gt; [0, 1]
range.

This fixes color being very green when using Gamescope HDR on HDMI
output which prefers YCC 4:4:4.

<title>drm/amd/display: Fix set scaling doesn's work</title>

commit 040625ab82ce6dca7772cb3867fe5c9eb279a344 upstream.

[Why]
Setting scaling does not correctly update CRTC state. As a result
dc stream state's src (composition area) &amp;&amp; dest (addressable area)
was not calculated as expected. This causes set scaling doesn's work.

[How]
Correctly update CRTC state when setting scaling property.

[ Upstream commit ca54639c7752edf1304d92ff4d0c049d4efc9ba0 ]

As comment of pci_get_class() says, it returns a pci_device with its
refcount increased and decreased the refcount for the input parameter
@from if it is not NULL.

If we break the loop in amdgpu_atrm_get_bios() with 'pdev' not NULL, we
need to call pci_dev_put() to decrease the refcount. Add the missing
pci_dev_put() to avoid refcount leak.

Calling drm_connector_update_edid_property() in

the system every 10 seconds on polled outputs so revert this

drm_display_info is updated by drm_get_edid() or
drm_connector_update_edid_property(). In the amdgpu driver it is almost
always updated when the edid is read in amdgpu_connector_get_edid(),
but not always.  Change amdgpu_connector_get_edid() and
amdgpu_connector_free_edid() to keep drm_display_info updated.

commit 44035ec2fde1114254ee465f9ba3bb246b0b6283 upstream.

There's been a very long running bug that seems to have been neglected for
a while, where amdgpu consistently triggers a KASAN error at start:

  BUG: KASAN: global-out-of-bounds in read_indirect_azalia_reg+0x1d4/0x2a0 [amdgpu]
  Read of size 4 at addr ffffffffc2274b28 by task modprobe/1889

After digging through amd's rather creative method for accessing registers,
I eventually discovered the problem likely has to do with the fact that on
my dce120 GPU there are supposedly 7 sets of audio registers. But we only
define a register mapping for 6 sets.

So, fix this and fix the KASAN warning finally.

<title>drm/amd/display: fix overflow on MIN_I64 definition</title>

<content type='text'>
[ Upstream commit 6ae0632d17759852c07e2d1e0a31c728eb6ba246 ]

The definition of MIN_I64 in bw_fixed.c can cause gcc to whinge about
integer overflow, because it is treated as a positive value, which is
then negated. The temporary positive value is not necessarily
representable.

This causes the following warning:
../drivers/gpu/drm/amd/amdgpu/../display/dc/dml/calcs/bw_fixed.c:30:19:
warning: integer overflow in expression ‘-9223372036854775808’ of type
‘long long int’ results in ‘-9223372036854775808’ [-Woverflow]
  30 |         (int64_t)(-(1LL &lt;&lt; 63))
     |                   ^

Writing out (-MAX_I64 - 1) works instead.

[ Upstream commit 6ae0632d17759852c07e2d1e0a31c728eb6ba246 ]

The definition of MIN_I64 in bw_fixed.c can cause gcc to whinge about
integer overflow, because it is treated as a positive value, which is
then negated. The temporary positive value is not necessarily
representable.

This causes the following warning:
../drivers/gpu/drm/amd/amdgpu/../display/dc/dml/calcs/bw_fixed.c:30:19:
warning: integer overflow in expression ‘-9223372036854775808’ of type
‘long long int’ results in ‘-9223372036854775808’ [-Woverflow]
  30 |         (int64_t)(-(1LL &lt;&lt; 63))
     |                   ^

Writing out (-MAX_I64 - 1) works instead.
