commit f965b68188ab59a40a421ced1b05a2fea638465c upstream.
Init value of some display vregs rea inherited from host pregs. When
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
from current configuration (only PIPE_A) and the virtual EDID.

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.

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)

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 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).

[ Upstream commit 9941b8129030c9202aaf39114477a0e58c0d6ffc ]
[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.

This change adds the below gpu memory tracepoint:
gpu_mem/gpu_mem_total: track global or proc gpu memory total usages
Per process tracking of total gpu memory usage in the gem layer is not
appropriate and hard to implement with trivial overhead. So for the gfx
device driver layer to track total gpu memory usage both globally and
per process in an easy and uniform way is to integrate the tracepoint in
this patch to the underlying varied implementations of gpu memory
tracking system from vendors.
Putting this tracepoint in the common trace events can not only help
wean the gfx drivers off of debugfs but also greatly help the downstream
Android gpu vendors because debugfs is to be deprecated in the upcoming
Android release. Then the gpu memory tracking of both Android kernel and
the upstream linux kernel can stay closely, which can benefit the whole
kernel eco-system in the long term.

page-flags: define PG_reserved behavior on compound pages
As far as I can see there's no users of PG_reserved on compound pages.
Let's use PF_NO_COMPOUND here.
it has been illegal to combine GFP_COMP with SetPageReserved, so lets
stop doing both and leave the dma layer to its own devices.

[ Upstream commit 8732fe46b20c951493bfc4dba0ad08efdf41de81 ]
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 -

Create a new connector property to program colorspace to sink
devices. Modern sink devices support more than 1 type of
colorspace like 601, 709, BT2020 etc. This helps to switch
based on content type which is to be displayed. The decision
lies with compositors as to in which scenarios, a particular
colorspace will be picked.
This will be helpful mostly to switch to higher gamut colorspaces
like BT2020 when the media content is encoded as BT2020. Thereby
giving a good visual experience to users.
The expectation from userspace is that it should parse the EDID
and get supported colorspaces. Use this property and switch to the
one supported. Sink supported colorspaces should be retrieved by
userspace from EDID and driver will not explicitly expose them.
Basically the expectation from userspace is:
- Set up CRTC DEGAMMA/CTM/GAMMA to convert to some sink
colorspace
- Set this new property to let the sink know what it
converted the CRTC output to.
v2: Addressed Maarten and Ville's review comments. Enhanced
the colorspace enum to incorporate both HDMI and DP supported
colorspaces. Also, added a default option for colorspace.
v3: Removed Adobe references from enum definitions as per
Ville, Hans Verkuil and Jonas Karlman suggestions. Changed
Default to an unset state where driver will assign the colorspace
is not chosen by user, suggested by Ville and Maarten. Addressed
other misc review comments from Maarten. Split the changes to
have separate colorspace property for DP and HDMI.
v4: Addressed Chris and Ville's review comments, and created a
common colorspace property for DP and HDMI, filtered the list
based on the colorspaces supported by the respective protocol
standard.
v5: Made the property creation helper accept enum list based on
platform capabilties as suggested by Shashank. Consolidated HDMI
and DP property creation in the common helper.
v6: Addressed Shashank's review comments.
v7: Added defines instead of enum in uapi as per Brian Starkey's
suggestion in order to go with string matching at userspace. Updated
the commit message to add more details as well kernel docs.
v8: Addressed Maarten's review comments.
v9: Removed macro defines from uapi as per Brian Starkey and Daniel
Stone's comments and moved to drm include file. Moved back to older
design with exposing all HDMI colorspaces to userspace since infoframe
