commit 5d230bc91f6c15e5d281f2851502918d98b9e770 upstream.
We need to allocate a large enough buffer for the
session info, otherwise the IB test can overwrite
other memory.
v2: - session info is 128K according to mesa
- use the same session info for create and destroy

commit 984d7a929ad68b7be9990fc9c5cfa5d5c9fc7942 upstream.
Bail from the pci_driver probe function instead of from the drm_driver
load function.
This avoid /dev/dri/card0 temporarily getting registered and then
unregistered again, sending unwanted add / remove udev events to
userspace.
Specifically this avoids triggering the (userspace) bug fixed by this
plymouth merge-request:
https://gitlab.freedesktop.org/plymouth/plymouth/merge_requests/59
Note that despite that being a userspace bug, not sending unnecessary
udev events is a good idea in general.

commit 5b3ec8134f5f9fa1ed0a538441a495521078bbee upstream.
Panfrost uses multiple schedulers (one for each slot, so 2 in reality),
and on a timeout has to stop all the schedulers to safely perform a
reset. However more than one scheduler can trigger a timeout at the same
time. This race condition results in jobs being freed while they are
still in use.
When stopping other slots use cancel_delayed_work_sync() to ensure that
any timeout started for that slot has completed. Also use
mutex_trylock() to obtain reset_lock. This means that only one thread
attempts the reset, the other threads will simply complete without doing
anything (the first thread will wait for this in the call to
cancel_delayed_work_sync()).
While we're here and since the function is already dependent on
sched_job not being NULL, let's remove the unnecessary checks.

commit 941f2f72dbbe0cf8c2d6e0b180a8021a0ec477fa upstream.
Commit 4daa4fba3a38 ("gpu: drm: ttm: Adding new return type vm_fault_t")
broke TTM prefaulting. Since vmf_insert_mixed() typically always returns
VM_FAULT_NOPAGE, prefaulting stops after the second PTE.
Restore (almost) the original behaviour. Unfortunately we can no longer
with the new vm_fault_t return type determine whether a prefaulting
PTE insertion hit an already populated PTE, and terminate the insertion
loop. Instead we continue with the pre-determined number of prefaults.

commit b925708f28c2b7a3a362d709bd7f77bc75c1daac upstream.
Since dropping the set-to-gtt-domain in commit a679f58d0510 ("drm/i915:
Flush pages on acquisition"), we no longer mark the contents as dirty on
a write fault. This has the issue of us then not marking the pages as
dirty on releasing the buffer, which means the contents are not written
out to the swap device (should we ever pick that buffer as a victim).
Notably, this is visible in the dumb buffer interface used for cursors.
Having updated the cursor contents via mmap, and swapped away, if the
shrinker should evict the old cursor, upon next reuse, the cursor would
be invisible.
E.g. echo 80 > /proc/sys/kernel/sysrq ; echo f > /proc/sysrq-trigger

commit 282b7fd5f5ab4eba499e1162c1e2802c6d0bb82e upstream.
This allows userspace to use "legacy" mode for push constants, where
they are committed at 3DPRIMITIVE or flush time, rather than being
committed at 3DSTATE_BINDING_TABLE_POINTERS_XS time. Gen6-8 and Gen11
both use the "legacy" behavior - only Gen9 works in the "new" way.
Conflating push constants with binding tables is painful for userspace,
we would like to be able to avoid doing so.

commit 698c1aa9f83b618de79e9e5e19a58f70a4a6ae0f upstream.
On the ThinkPad P71, we have one eDP connector exposed along with 5 DP
connectors, resulting in a total of 11 TMDS encoders. Since the GPU on
this system is also capable of MST, we create an additional 4 fake MST
encoders for each DP port. Unfortunately, we also do this for the eDP
port as well, resulting in:
1 eDP port: +1 TMDS encoder
+4 DPMST encoders
5 DP ports: +2 TMDS encoders
+4 DPMST encoders
*5 ports
== 35 encoders
Which breaks things, since DRM has a hard coded limit of 32 encoders.
So, fix this by not creating MSTMs for any eDP connectors. This brings
us down to 31 encoders, although we can do better.
This fixes driver probing for nouveau on the ThinkPad P71.

commit e2c4ed148cf3ec8669a1d90dc66966028e5fad70 upstream.
The OMAP36xx and AM/DM37x TRMs say that the maximum divider for DSS fclk
(in CM_CLKSEL_DSS) is 32. Experimentation shows that this is not
correct, and using divider of 32 breaks DSS with a flood or underflows
and sync losts. Dividers up to 31 seem to work fine.
There is another patch to the DT files to limit the divider correctly,
but as the DSS driver also needs to know the maximum divider to be able
to iteratively find good rates, we also need to do the fix in the DSS
driver.

commit 26b1d3b527e7bf3e24b814d617866ac5199ce68d upstream.
The -modesetting ddx has a totally broken idea of how atomic works:
- doesn't disable old connectors, assuming they get auto-disable like
with the legacy setcrtc
- assumes ASYNC_FLIP is wired through for the atomic ioctl
- not a single call to TEST_ONLY
Iow the implementation is a 1:1 translation of legacy ioctls to
atomic, which is a) broken b) pointless.
We already have bugs in both i915 and amdgpu-DC where this prevents us
from enabling neat features.
If anyone ever cares about atomic in X we can easily add a new atomic
level (req->value == 2) for X to get back the shiny toys.
Since these broken versions of -modesetting have been shipping,
there's really no other way to get out of this bind.
v2:
- add an informational dmesg output (Rob, Ajax)
- reorder after the DRIVER_ATOMIC check to avoid useless noise (Ilia)
- allow req->value > 2 so that X can do another attempt at atomic in
the future
v3: Go with paranoid, insist that the X should be first (suggested by
Rob)

It's never been wired up. Only userspace that tried to use it (and
didn't actually check whether anything works, but hey it builds) is
the -modesetting atomic implementation. And we just shut that up.
If there's anyone else then we need to silently accept this flag no
matter what, and find a new one. Because once a flag is tainted, it's
lost.

[ Upstream commit a1af2afbd244089560794c260b2d4326a86e39b6 ]
Some, mostly Fermi, vbioses appear to have zero max voltage. That causes Nouveau to not parse voltage entries, thus users not being able to set higher clocks.
When changing this value Nvidia driver still appeared to ignore it, and I wasn't able to find out why, thus the code is ignoring the value if it is zero.

[ Upstream commit 1e339ab2ac3c769c1b06b9fb7d532f8495ebc56d ]
On Turing, an input LUT is required to transform inputs in fixed-point
formats to FP16 for the internal display pipe. We provide an identity
mapping whenever a window is enabled for this reason.
HW has error checks to ensure when the input is already FP16, that the
input LUT is also disabled.

[ Upstream commit a463b263032f7c98c5912207db43be1aa34a6438 ]
[Why]
The math on deciding on how many
"frames to insert" sometimes sent us over the max refresh rate.
Also integer overflow can occur if we have high refresh rates.
[How]
Instead of clipping the frame duration such that it doesn’t go below the min,
just remove a frame from the number of frames to insert. +
Use unsigned long long for intermediate calculations to prevent
integer overflow.

[Why]
When endpoint is at the boundary of a region, such as at 2^0=1
we find that the last segment has a sharp slope and some points

If end point is 1, which is exactly at the 2^0 region boundary, we
need to program an additional region beyond this point.

radeon_connector_set_property()
[ Upstream commit f3eb9b8f67bc28783eddc142ad805ebdc53d6339 ]
In radeon_connector_set_property(), there is an if statement on line 743
to check whether connector->encoder is NULL:
if (connector->encoder)
When connector->encoder is NULL, it is used on line 755:
if (connector->encoder->crtc)
Thus, a possible null-pointer dereference may occur.
To fix this bug, connector->encoder is checked before being used.
This bug is found by a static analysis tool STCheck written by us.

[ Upstream commit 3389669ac5ea598562673c04971d7bb0fab0e9f1 ]
The mipi_dbi helper is missing a dependency on DRM_KMS_HELPER and putting
that in revealed this problem:
drivers/video/fbdev/Kconfig:12:error: recursive dependency detected!
drivers/video/fbdev/Kconfig:12: symbol FB is selected by DRM_KMS_FB_HELPER
drivers/gpu/drm/Kconfig:75: symbol DRM_KMS_FB_HELPER depends on DRM_KMS_HELPER
drivers/gpu/drm/Kconfig:69: symbol DRM_KMS_HELPER is selected by TINYDRM_MIPI_DBI
drivers/gpu/drm/tinydrm/Kconfig:11: symbol TINYDRM_MIPI_DBI is selected by TINYDRM_HX8357D
drivers/gpu/drm/tinydrm/Kconfig:15: symbol TINYDRM_HX8357D depends on BACKLIGHT_CLASS_DEVICE
drivers/video/backlight/Kconfig:144: symbol BACKLIGHT_CLASS_DEVICE is selected by FB_BACKLIGHT
drivers/video/fbdev/Kconfig:187: symbol FB_BACKLIGHT depends on FB
A symbol that selects DRM_KMS_HELPER can not depend on
BACKLIGHT_CLASS_DEVICE. The reason for this is that DRM_KMS_FB_HELPER
selects FB instead of depending on it.
The tinydrm drivers have somehow gotten away with depending on
BACKLIGHT_CLASS_DEVICE because DRM_TINYDRM selects DRM_KMS_HELPER and the
drivers depend on that symbol.
An audit shows that all DRM drivers that select DRM_KMS_HELPER and use
BACKLIGHT_CLASS_DEVICE, selects it:
DRM_TILCDC, DRM_GMA500, DRM_SHMOBILE, DRM_NOUVEAU, DRM_FSL_DCU,
DRM_I915, DRM_RADEON, DRM_AMDGPU, DRM_PARADE_PS8622
Documentation/kbuild/kconfig-language.txt has a note regarding select:
1. 'select should be used with care since it doesn't visit dependencies.'
This is not a problem since BACKLIGHT_CLASS_DEVICE doesn't have any
dependencies.
2. 'In general use select only for non-visible symbols'
BACKLIGHT_CLASS_DEVICE is user visible.
The real solution to this would be to have DRM_KMS_FB_HELPER depend on the
user visible symbol FB. That is a can of worms I'm not willing to tackle.
I fear that such a change will result in me handling difficult fallouts
for the next weeks. So I'm following DRM suite here.

[ Upstream commit f8c6bfc612b56f02e1b8fae699dff12738aaf889 ]
The horizontal blanking periods are too short, as the values are
specified for a single LVDS channel. Since this panel is dual LVDS
they need to be doubled. With this change the panel reaches its
nominal vrefresh rate of 60Fps, instead of the 64Fps with the
current wrong blanking.
Philipp Zabel added:
The datasheet specifies 960 active clocks + 40/128/160 clocks blanking
on each of the two LVDS channels (min/typical/max), so doubled this is
now correct.

When vkms invoke drm_universal_plane_init(), it sets 0 for
possible_crtcs parameter which means that planes can't be attached to
any CRTC. It currently works due to some safeguard in the drm_crtc file;
however, it is possible to identify the problem by trying to append a
second connector. This patch fixes this issue by modifying
vkms_plane_init() to accept an index parameter which makes the code a
little bit more flexible and avoid set zero to possible_crtcs.

According to the datasheet tc358767 can transfer up to 16 bytes via
its AUX channel, so the artificial limit of 8 appears to be too
low. However only up to 15-bytes seem to be actually supported and
trying to use 16-byte transfers results in transfers failing
sporadically (with bogus status in case of I2C transfers), so limit it
to 15.

[ Upstream commit 18d0952a838ba559655b0cd9cf85097ad63d9bca ]
The issue we have is that the crc worker might fall behind. We've
tried to handle this by tracking both the earliest frame for which it
still needs to compute a crc, and the last one. Plus when the
crtc_state changes, we have a new work item, which are all run in
order due to the ordered workqueue we allocate for each vkms crtc.
Trouble is there's been a few small issues in the current code:
- we need to capture frame_end in the vblank hrtimer, not in the
worker. The worker might run much later, and then we generate a lot
of crc for which there's already a different worker queued up.
- frame number might be 0, so create a new crc_pending boolean to
track this without confusion.
- we need to atomically grab frame_start/end and clear it, so do that
all in one go. This is not going to create a new race, because if we
race with the hrtimer then our work will be re-run.
- only race that can happen is the following:
1. worker starts
2. hrtimer runs and updates frame_end
3. worker grabs frame_start/end, already reading the new frame_end,
and clears crc_pending
4. hrtimer calls queue_work()
5. worker completes
6. worker gets re-run, crc_pending is false
Explain this case a bit better by rewording the comment.
v2: Demote warning level output to debug when we fail to requeue, this
is expected under high load when the crc worker can't quite keep up.
