user_atom.atom_number can be indirectly controlled by user-space,
hence leading to a potential exploitation
of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/gpu/arm/midgard/mali_kbase_jd.c:1397 kbase_jd_submit() warn:
potential spectre issue 'jctx->atoms' [r]
katom = &jctx->atoms[user_atom.atom_number];
Fix this by sanitizing user_atom.atom_number
before 'katom = &jctx->atoms[user_atom.atom_number];'.
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

commit 48eaeb7664 upstream.
We've moved the override and firmware EDID (simply "override EDID" from
now on) handling to the low level drm_do_get_edid() function in order to
transparently use the override throughout the stack. The idea is that
you get the override EDID via the ->get_modes() hook.
Unfortunately, there are scenarios where the DDC probe in drm_get_edid()
called via ->get_modes() fails, although the preceding ->detect()
succeeds.
In the case reported by Paul Wise, the ->detect() hook,
intel_crt_detect(), relies on hotplug detect, bypassing the DDC. In the
case reported by Ilpo Järvinen, there is no ->detect() hook, which is
interpreted as connected. The subsequent DDC probe reached via
->get_modes() fails, and we don't even look at the override EDID,
resulting in no modes being added.
Because drm_get_edid() is used via ->detect() all over the place, we
can't trivially remove the DDC probe, as it leads to override EDID
effectively meaning connector forcing. The goal is that connector
forcing and override EDID remain orthogonal.
Generally, the underlying problem here is the conflation of ->detect()
and ->get_modes() via drm_get_edid(). The former should just detect, and
the latter should just get the modes, typically via reading the EDID. As
long as drm_get_edid() is used in ->detect(), it needs to retain the DDC
probe. Or such users need to have a separate DDC probe step first.
The EDID caching between ->detect() and ->get_modes() done by some
drivers is a further complication that prevents us from making
drm_do_get_edid() adapt to the two cases.
Work around the regression by falling back to a separate attempt at
getting the override EDID at drm_helper_probe_single_connector_modes()
level. With a working DDC and override EDID, it'll never be called; the
override EDID will come via ->get_modes(). There will still be a failing
DDC probe attempt in the cases that require the fallback.
v2:
- Call drm_connector_update_edid_property (Paul)
- Update commit message about EDID caching (Daniel)

commit d74408f528 upstream.
Our SDVO audio support is pretty bogus. We can't push audio over the
SDVO bus, so trying to enable audio in the SDVO control register doesn't
do anything. In fact it looks like the SDVO encoder will always mix in
the audio coming over HDA, and there's no (at least documented) way to
disable that from our side. So HDMI audio does work currently on gen4
but only by luck really. On gen3 it got broken by the referenced commit.
And what has always been missing on every platform is the ELD.
To pass the ELD to the audio driver we need to write it to magic buffer
in the SDVO encoder hardware which then gets pulled out via HDA in the
other end. Ie. pretty much the same thing we had for native HDMI before
we started to just pass the ELD between the drivers. This sort of
explains why we even have that silly hardware buffer with native HDMI.
$ cat /proc/asound/card0/eld#1.0
-monitor_present 0
-eld_valid 0
+monitor_present 1
+eld_valid 1
+monitor_name LG TV
+connection_type HDMI
+...
This also fixes our state readout since we can now query the SDVO
encoder about the state of the "ELD valid" and "presence detect"
bits. As mentioned those don't actually control whether audio
gets sent over the HDMI cable, but it's the best we can do. And with
the state checker appeased we can re-enable HDMI audio for gen3.

("drm/ttm: Quick-test mmap offset in ttm_bo_mmap()")
Setting CONFIG_NOUVEAU_LEGACY_CTX_SUPPORT=n (added by commit: b30a43ac71)
causes the build to fail with:
ERROR: "drm_legacy_mmap" [drivers/gpu/drm/nouveau/nouveau.ko] undefined!
This does not happend upstream as the offending code got removed in:
bed2dd8421 ("drm/ttm: Quick-test mmap offset in ttm_bo_mmap()")
Fix that by adding check for CONFIG_NOUVEAU_LEGACY_CTX_SUPPORT around
the drm_legacy_mmap() call.
Also, as Sven Joachim pointed out, we need to make the check in
CONFIG_NOUVEAU_LEGACY_CTX_SUPPORT=n case return -EINVAL as its done
for basically all other gpu drivers, especially in upstream kernels
drivers/gpu/drm/ttm/ttm_bo_vm.c as of the upstream commit bed2dd8421.
NOTE. This is a minimal stable-only fix for trees where b30a43ac71 is
backported as the build error affects nouveau only.

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.

Upstream does not have that problem, as commit bed2dd8421 ("drm/ttm:
Quick-test mmap offset in ttm_bo_mmap()") has removed the use of
drm_legacy_mmap from nouveau_ttm.c. Unfortunately that commit does not
apply in 5.1.9.
The ensuing discussion proposed a number of one-off patches, but no
solid agreement was made, so just revert the commit for now to get
people's systems building again.

[ Upstream commit a1e07ba89d ]
[Why]
The input color space for the plane was previously ignored even if it
was set.
If a limited range YUV format was given to DC then the
wrong color transformation matrix was being used since DC assumed that
it was full range instead.
[How]
Respect the given color_space format for the plane if it isn't
COLOR_SPACE_UNKNOWN. Otherwise, use the implicit default since DM
didn't specify.

[ Upstream commit d2434e4d94 ]
Cursor position updates were accidentally causing us to attempt to interlock
window with window immediate, and without a matching window immediate update,
NVDisplay could hang forever in some circumstances.
Fixes suspend/resume on (at least) Quadro RTX4000 (TU104).

[ Upstream commit 67793bd3b3 ]
The driver currently sets register 0xfb (Low Refresh Rate) based on the
value of mode->vrefresh. Firstly, this field is specified to be in Hz,
but the magic numbers used by the code are Hz * 1000. This essentially
leads to the low refresh rate always being set to 0x01, since the
vrefresh value will always be less than 24000. Fix the magic numbers to
be in Hz.
Secondly, according to the comment in drm_modes.h, the field is not
supposed to be used in a functional way anyway. Instead, use the helper
function drm_mode_vrefresh().

[ Upstream commit a0b694d0af ]
HW has error checks in place which check that pixel depth is explicitly
provided on DP, while HDMI has a "default" setting that we use.
In multi-display configurations with identical modelines, but different
protocols (HDMI + DP, in this case), it was possible for the DP head to
get swapped to the head which previously drove the HDMI output, without
updating HeadSetControlOutputResource(), triggering the error check and
hanging the core update.

[ Upstream commit 13d03e9daf ]
Where possible, we want the failsafe link configuration (one which won't
hang the OR during modeset because of not enough bandwidth for the mode)
to also be supported by the sink.
This prevents "link rate unsupported by sink" messages when link training
fails.
