commit b0f84a84fff180718995b1269da2988e5b28be42 upstream.
The bulk SPDX addition made all these files into GPL-2.0 licensed files.
However the remainder of the project is MIT-licensed, these files
were simply missing the boiler plate and got caught up in the global update.
Fixes: 96ac6d4351004 (treewide: Add SPDX license identifier - Kbuild)

commit 3bd532692d93a9c72f4f11e38437b30c0e13007f upstream.
The simple_strtol() function is deprecated. kstrto[l,u32]() is
the correct replacement as it can properly handle overflows.
This patch replaces the deprecated simple_strtol() use introduced recently.
As clk is of type uint32_t, we are safe to use kstrtou32().
It is also safe to return zero on string parsing error,
similar to the case of returning zero if buf is empty in parse_clk().

commit f965b68188ab59a40a421ced1b05a2fea638465c upstream.

host display in different status, i.e. all monitors unpluged, different
display configurations, etc., GVT virtual display setup don't consistent
thus may lead to guest driver consider display goes malfunctional.
The added init vreg values are based on PRMs and fixed by calcuation

commit e6142dd511425cb827b5db869f489eb81f5f994d upstream.
[why]
During hotplug, a DP port may be connected to the sink through
passive adapter which does not support DPCD reads. Issuing reads
without checking for this condition will result in errors
[how]
Ensure the link is in aux_mode before initiating operation that result

commit 72a7a9925e2beea09b109dffb3384c9bf920d9da upstream.
As i915 won't allocate extra PDP for current default PML4 table,
so for 3-level ppgtt guest, we would hit kernel pointer access
failure on extra PDP pointers. So this trys to bypass that now.
It won't impact real shadow PPGTT setup, so guest context still
works.
This is verified on 4.15 guest kernel with i915.enable_ppgtt=1
to force on old aliasing ppgtt behavior.

hwmgr->pm_en is initialized at hwmgr_hw_init.
during amdgpu_device_init, there is amdgpu_asic_reset that calls to
soc15_asic_reset (for V320 usecase, Vega10 asic), in which:
1) soc15_asic_reset_method calls to pp_get_asic_baco_capability (pm_en)
2) soc15_asic_baco_reset calls to pp_set_asic_baco_state (pm_en)
pm_en is used in the above two cases while it has not yet been initialized

commit 933db73351d359f74b14f4af095808260aff11f9 upstream.
qxl_release should not be accesses after qxl_push_*_ring_release() calls:
userspace driver can process submitted command quickly, move qxl_release
into release_ring, generate interrupt and trigger garbage collector.
It can lead to crashes in qxl driver or trigger memory corruption
in some kmalloc-192 slab object
Gerd Hoffmann proposes to swap the qxl_release_fence_buffer_objects() +
qxl_push_{cursor,command}_ring_release() calls to close that race window.

commit 87b7ebc2e16c14d32a912f18206a4d6cc9abc3e8 upstream.
[why]
We have seen a green screen after resume from suspend in a Raven system
connected with two displays (HDMI and DP) on X based system. We noticed
that this issue is related to bad DCC metadata from user space which may
generate hangs and consequently an underflow on HUBP. After taking a
deep look at the code path we realized that after resume we try to
restore the commit with the DCC enabled framebuffer but the framebuffer
is no longer valid.
[how]
This problem was only reported on Raven based system and after suspend,
for this reason, this commit adds a new parameter on
fill_plane_dcc_attributes() to give the option of disabling DCC
programmatically. In summary, for disabling DCC we first verify if is a
Raven system and if it is in suspend; if both conditions are true we
disable DCC temporarily, otherwise, it is enabled.

commit 2cc450ceaae4febc1539975247d235eb06c11979 upstream.
[Why]
Pitch, DCC, rotation and mirroring can result in updates that are not
UPDATE_TYPE_FAST but UPDATE_TYPE_MED instead. DC needs dc_plane_info
and dc_plane_size to make this determination and we aren't currently
passing this into DC during atomic check.
Underflow (visible or non-visible) can occur if we don't validate this
correctly. This also will generally trigger p-state warnings, typically
via the cursor handler when locking.
[How]
Get the framebuffer tiling flags and generate the required structures
for DC in dm_determine_update_type_for_commit.

commit 6292b8efe32e6be408af364132f09572aed14382 upstream.
The DispID DTD pixel clock is documented as:
"00 00 00 h → FF FF FF h | Pixel clock ÷ 10,000 0.01 → 167,772.16 Mega Pixels per Sec"
Which seems to imply that we to add one to the raw value.
Reality seems to agree as there are tiled displays in the wild
which currently show a 10kHz difference in the pixel clock
between the tiles (one tile gets its mode from the base EDID,
the other from the DispID block).

commit 9941b8129030c9202aaf39114477a0e58c0d6ffc upstream.
[Why]
In some scenario like 1366x768 VSR enabled connected with a 4K monitor
and playing 4K video in clone mode, underflow will be observed due to
decrease dppclk when previouse surface scan isn't finished
[How]
In this use case, surface flip is switching between 4K and 1366x768,
1366x768 needs smaller dppclk, and when decrease the clk and previous
surface scan is for 4K and scan isn't done, underflow will happen. Not
doing optimize bandwidth in case of flip pending.

commit 40b697e256ccdb88aaff424b44b4d300eb8460e8 upstream.
The GC860 has one GPU device which has a 2d and 3d core. In this case
we want to expose perfmon information for both cores.
The driver has one array which contains all possible perfmon domains
with some meta data - doms_meta. Here we can see that for the GC860
two elements of that array are relevant:
doms_3d: is at index 0 in the doms_meta array with 8 perfmon domains
doms_2d: is at index 1 in the doms_meta array with 1 perfmon domain
The userspace driver wants to get a list of all perfmon domains and
their perfmon signals. This is done by iterating over all domains and
their signals. If the userspace driver wants to access the domain with
id 8 the kernel driver fails and returns invalid data from doms_3d with
and invalid offset.
This results in:
Unable to handle kernel paging request at virtual address 00000000
On such a device it is not possible to use the userspace driver at all.
The fix for this off-by-one error is quite simple.

nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 409800 [ TIMEOUT ]
appearing in dmesg, likely followed by many other failures being logged.
Karol found this WAR for the issue a while back, but efforts to isolate
the root cause and proper fix have not yielded success so far. I've
modified the original patch to include a few more details, limit it to
GP107/GP108 by default, and added a config option to override this choice.

Current mode validation impedes setting up some video modes which should
be supported otherwise. Namely 1920x1200@60Hz.
Fix this by lowering the minimum HDMI state machine clock to pixel clock

commit 434fdb51513bf3057ac144d152e6f2f2b509e857 upstream.
Fixes the infamous 'runtime PM' bug many users are facing on Laptops with
Nvidia Pascal GPUs by skipping said PCI power state changes on the GPU.
Depending on the used kernel there might be messages like those in demsg:
"nouveau 0000:01:00.0: Refused to change power state, currently in D3"
"nouveau 0000:01:00.0: can't change power state from D3cold to D0 (config
space inaccessible)"
followed by backtraces of kernel crashes or timeouts within nouveau.
It's still unkown why this issue exists, but this is a reliable workaround
and solves a very annoying issue for user having to choose between a
crashing kernel or higher power consumption of their Laptops.

commit b92103b559c77abc5f8b7bec269230a219c880b7 upstream.
find_vma_intersection(mm, start, end) only guarantees that end is greater
than or equal to vma->vm_start but doesn't guarantee that start is
greater than or equal to vma->vm_start. The calculation for the
intersecting range in nouveau_svmm_bind() isn't accounting for this and
can call migrate_vma_setup() with a starting address less than
vma->vm_start. This results in migrate_vma_setup() returning -EINVAL for
the range instead of nouveau skipping that part of the range and migrating
the rest.

commit 8732fe46b20c951493bfc4dba0ad08efdf41de81 upstream.
The issues caused by:
commit 64e62bdf04ab ("drm/dp_mst: Remove VCPI while disabling topology
mgr")
Prompted me to take a closer look at how we clear the payload state in
general when disabling the topology, and it turns out there's actually
two subtle issues here.
The first is that we're not grabbing &mgr.payload_lock when clearing the
payloads in drm_dp_mst_topology_mgr_set_mst(). Seeing as the canonical
lock order is &mgr.payload_lock -> &mgr.lock (because we always want
&mgr.lock to be the inner-most lock so topology validation always
works), this makes perfect sense. It also means that -technically- there
could be racing between someone calling
drm_dp_mst_topology_mgr_set_mst() to disable the topology, along with a
modeset occurring that's modifying the payload state at the same time.
The second is the more obvious issue that Wayne Lin discovered, that
we're not clearing proposed_payloads when disabling the topology.
I actually can't see any obvious places where the racing caused by the
first issue would break something, and it could be that some of our
higher-level locks already prevent this by happenstance, but better safe
then sorry. So, let's make it so that drm_dp_mst_topology_mgr_set_mst()
first grabs &mgr.payload_lock followed by &mgr.lock so that we never
race when modifying the payload state. Then, we also clear
proposed_payloads to fix the original issue of enabling a new topology
with a dirty payload state. This doesn't clear any of the drm_dp_vcpi
structures, but those are getting destroyed along with the ports anyway.
Changes since v1:
* Use sizeof(mgr->payloads[0])/sizeof(mgr->proposed_vcpis[0]) instead -

->test_and_set_bit
here trigger dma_fence_release happen due to the zero of fence refcount.
->dma_fence_put
->dma_fence_release
->drm_sched_fence_release_scheduled
->call_rcu
here make the union fled “cb_list” at finished fence
to NULL because struct rcu_head contains two pointer
which is same as struct list_head cb_list
Therefore, to hold the reference of finished fence at drm_sched_process_job
to prevent the null pointer during finished fence dma_fence_signal

commit dec9de2ada523b344eb2428abfedf9d6cd0a0029 upstream.
This fixes a problem found on the MacBookPro 2017 Retina panel:
The panel reports 10 bpc color depth in its EDID, and the
firmware chooses link settings at boot which support enough
bandwidth for 10 bpc (324000 kbit/sec aka LINK_RATE_RBR2
aka 0xc), but the DP_MAX_LINK_RATE dpcd register only reports
2.7 Gbps (multiplier value 0xa) as possible, in direct
contradiction of what the firmware successfully set up.
This restricts the panel to 8 bpc, not providing the full
color depth of the panel on Linux <= 5.5. Additionally, commit
'4a8ca46bae8a ("drm/amd/display: Default max bpc to 16 for eDP")'
introduced into Linux 5.6-rc1 will unclamp panel depth to
its full 10 bpc, thereby requiring a eDP bandwidth for all
modes that exceeds the bandwidth available and causes all modes
to fail validation -> No modes for the laptop panel -> failure
to set any mode -> Panel goes dark.
This patch adds a quirk specific to the MBP 2017 15" Retina
panel to override reported max link rate to the correct maximum
of 0xc = LINK_RATE_RBR2 to fix the darkness and reduced display
precision.
Please apply for Linux 5.6+ to avoid regressing Apple MBP panel
support.
