[ Upstream commit 7adc77aa0e11f25b0e762859219c70852cd8d56f ]

Method init is typically ordered by class in the FW image as ThreeD,
TwoD, Compute.

Due to a bug in parsing the FW into our internal format, we've been
accidentally sending Twod + Compute methods to the ThreeD class, as
well as Compute methods to the TwoD class - oops.

1899747eb7 drm/mediatek: handle events when enabling/disabling crtc
[ Upstream commit 411f5c1eacfebb1f6e40b653d29447cdfe7282aa ]

The driver currently handles vblank events only when updating planes on
an already enabled CRTC. The atomic update API however allows requesting
an event when enabling or disabling a CRTC. This currently leads to
event objects being leaked in the kernel and to events not being sent
out. Fix it.

To prevent warnings like this from happening in the future, make the
SOC15_WAIT_ON_RREG macro initialize its ret variable before the while
loop that can time out. This macro's return value is always checked so
it should set ret in both the success and fail path.

ff19c8c6ea drm/amd/display: Retrain dongles when SINK_COUNT becomes non-zero
[ Upstream commit 3eb6d7aca53d81ce888624f09cd44dc0302161e8 ]

[WHY]
Two years ago the patch referenced by the Fixes tag stopped running
dp_verify_link_cap_with_retries during DP detection when the reason
for the detection was a short-pulse interrupt. This effectively meant
that we were no longer doing the verify_link_cap training on active
dongles when their SINK_COUNT changed from 0 to 1.

A year ago this was partly remedied with:
commit 80adaebd2d41 ("drm/amd/display: Don't skip link training for empty dongle")

This made sure that we trained the dongle on initial hotplug (without
connected downstream devices).

This is all fine and dandy if it weren't for the fact that there are
some dongles on the market that don't like link training when SINK_COUNT
is 0 These dongles will in fact indicate a SINK_COUNT of 0 immediately
after hotplug, even when a downstream device is connected, and then
trigger a shortpulse interrupt indicating a SINK_COUNT change to 1.

In order to play nicely we will need our policy to not link train an
active DP dongle when SINK_COUNT is 0 but ensure we train it when the
SINK_COUNT changes to 1.

[HOW]
Call dp_verify_link_cap_with_retries on detection even when the detection
is triggered from a short pulse interrupt.

With this change we can also revert this commit which we'll do in a separate
follow-up change:
commit 80adaebd2d41 ("drm/amd/display: Don't skip link training for empty dongle")

5d358e7e2b drm/gma500: Fixup fbdev stolen size usage evaluation
[ Upstream commit fd1a5e521c3c083bb43ea731aae0f8b95f12b9bd ]

psbfb_probe performs an evaluation of the required size from the stolen
GTT memory, but gets it wrong in two distinct ways:
- The resulting size must be page-size-aligned;
- The size to allocate is derived from the surface dimensions, not the fb
  dimensions.

When two connectors are connected with different modes, the smallest will
be stored in the fb dimensions, but the size that needs to be allocated must
match the largest (surface) dimensions. This is what is used in the actual
allocation code.

Fix this by correcting the evaluation to conform to the two points above.
It allows correctly switching to 16bpp when one connector is e.g. 1920x1080
and the other is 1024x768.

4ecba33ec8 drm/dp_mst: Remove VCPI while disabling topology mgr
[ Upstream commit 64e62bdf04ab8529f45ed0a85122c703035dec3a ]

[Why]

This patch is trying to address the issue observed when hotplug DP
daisy chain monitors.

e.g.
src-mstb-mstb-sst -> src (unplug) mstb-mstb-sst -> src-mstb-mstb-sst
(plug in again)

Once unplug a DP MST capable device, driver will call
drm_dp_mst_topology_mgr_set_mst() to disable MST. In this function,
it cleans data of topology manager while disabling mst_state. However,
it doesn't clean up the proposed_vcpis of topology manager.
If proposed_vcpi is not reset, once plug in MST daisy chain monitors
later, code will fail at checking port validation while trying to
allocate payloads.

When MST capable device is plugged in again and try to allocate
payloads by calling drm_dp_update_payload_part1(), this
function will iterate over all proposed virtual channels to see if
any proposed VCPI's num_slots is greater than 0. If any proposed
VCPI's num_slots is greater than 0 and the port which the
specific virtual channel directed to is not in the topology, code then
fails at the port validation. Since there are stale VCPI allocations
from the previous topology enablement in proposed_vcpi[], code will fail
at port validation and reurn EINVAL.

[How]

Clean up the data of stale proposed_vcpi[] and reset mgr->proposed_vcpis
to NULL while disabling mst in drm_dp_mst_topology_mgr_set_mst().

1f1611dc1f drm: atmel-hlcdc: enable clock before configuring timing engine
[ Upstream commit 2c1fb9d86f6820abbfaa38a6836157c76ccb4e7b ]

Changing pixel clock source without having this clock source enabled
will block the timing engine and the next operations after (in this case
setting ATMEL_HLCDC_CFG(5) settings in atmel_hlcdc_crtc_mode_set_nofb()
will fail). It is recomended (although in datasheet this is not present)
to actually enabled pixel clock source before doing any changes on timing
enginge (only SAM9X60 datasheet specifies that the peripheral clock and
pixel clock must be enabled before using LCD controller).

4f46f59a5e drm: msm: mdp4: Adjust indentation in mdp4_dsi_encoder_enable
commit 251e3cb1418ff3f5061ee31335e346e852b16573 upstream.

Clang warns:

../drivers/gpu/drm/msm/disp/mdp4/mdp4_dsi_encoder.c:124:3: warning:
misleading indentation; statement is not part of the previous 'if'
[-Wmisleading-indentation]
         mdp4_crtc_set_config(encoder->crtc,

previous statement is here
        if (mdp4_dsi_encoder->enabled)
        ^

This warning occurs because there is a space after the tab on this line.
Remove it so that the indentation is consistent with the Linux kernel
coding style and clang no longer warns.

abc51506fc drm/amd/dm/mst: Ignore payload update failures
commit 58fe03d6dec908a1bec07eea7e94907af5c07eec upstream.

Disabling a display on MST can potentially happen after the entire MST
topology has been removed, which means that we can't communicate with
the topology at all in this scenario. Likewise, this also means that we
can't properly update payloads on the topology and as such, it's a good
idea to ignore payload update failures when disabling displays.
Currently, amdgpu makes the mistake of halting the payload update
process when any payload update failures occur, resulting in leaving
DC's local copies of the payload tables out of date.

This ends up causing problems with hotplugging MST topologies, and
causes modesets on the second hotplug to fail like so:

41be0c3295 Revert "drm/sun4i: dsi: Change the start delay calculation"
[ Upstream commit a00d17e0a71ae2e4fdaac46e1c12785d3346c3f2 ]

This reverts commit da676c6aa6413d59ab0a80c97bbc273025e640b2.

The original commit adds a start parameter to the calculation of the
start delay according to some old BSP versions from Allwinner. However,
there're two ways to add this delay -- add it in DSI controller or add
it in the TCON. Add it in both controllers won't work.

The code before this commit is picked from new versions of BSP kernel,
which has a comment for the 1 that says "put start_delay to tcon". By
checking the sun4i_tcon0_mode_set_cpu() in sun4i_tcon driver, it has
already added this delay, so we shouldn't repeat to add the delay in DSI
controller, otherwise the timing won't match.

6fab6dbff4 drm/radeon: fix bad DMA from INTERRUPT_CNTL2
[ Upstream commit 62d91dd2851e8ae2ca552f1b090a3575a4edf759 ]

The INTERRUPT_CNTL2 register expects a valid DMA address, but is
currently set with a GPU MC address.  This can cause problems on
systems that detect the resulting DMA read from an invalid address
(found on a Power8 guest).

Instead, use the DMA address of the dummy page because it will always
be safe.

of_parse_phandle() returns NULL.  This code is cleaner if we use the
managed devm_of_find_backlight() so the clean up is automatic.

2e7d73cb22 drm/msm/dsi: Implement reset correctly
[ Upstream commit 78e31c42261779a01bc73472d0f65f15378e9de3 ]

On msm8998, vblank timeouts are observed because the DSI controller is not
reset properly, which ends up stalling the MDP.  This is because the reset
logic is not correct per the hardware documentation.

The documentation states that after asserting reset, software should wait
some time (no indication of how long), or poll the status register until it
returns 0 before deasserting reset.

wmb() is insufficient for this purpose since it just ensures ordering, not
timing between writes.  Since asserting and deasserting reset occurs on the
same register, ordering is already guaranteed by the architecture, making
the wmb extraneous.

Since we would define a timeout for polling the status register to avoid a
possible infinite loop, lets just use a static delay of 20 ms, since 16.666
ms is the time available to process one frame at 60 fps.

[ Upstream commit f47bee2ba447bebc304111c16ef1e1a73a9744dd ]

These regs are write-only, and the hw throws a hissy-fit (ie. reboots)
when we try to read them for GPU state snapshot, in response to a GPU
hang.  It is rather impolite when GPU recovery triggers an insta-
reboot, so lets remove the TPL1 registers from the snapshot.

[ Upstream commit fc19cbb785d7bbd1a1af26229b5240a3ab332744 ]

If mdp5_cfg_init fails because of an unknown major version, a null pointer
dereference occurs.  This is because the caller of init expects error
pointers, but init returns NULL on error.  Fix this by returning the
expected values on error.

c1e9cfc815 drm/xen-front: Fix mmap attributes for display buffers
[ Upstream commit 24ded292a5c2ed476f01c77fee65f8320552cd27 ]

When GEM backing storage is allocated those are normal pages,
so there is no point using pgprot_writecombine while mmaping.
This fixes mismatch of buffer pages' memory attributes between
the frontend and backend which may cause screen artifacts.

66779aa306 drm/fb-helper: generic: Fix setup error path
[ Upstream commit 6e1490cf439aa86b104e5124c36275b964238e1f ]

If register_framebuffer() fails during fbdev setup we will leak the
framebuffer, the GEM buffer and the shadow buffer for defio. This is
because drm_fb_helper_fbdev_setup() just calls drm_fb_helper_fini() on
error not taking into account that register_framebuffer() can fail.

Since the generic emulation uses DRM client for its framebuffer and
backing buffer in addition to a shadow buffer, it's necessary to open code
drm_fb_helper_fbdev_setup() to properly handle the error path.

Error cleanup is removed from .fb_probe and is handled by one function for
all paths.

035e304f95 drm/dp_mst: Skip validating ports during destruction, just ref
[ Upstream commit c54c7374ff44de5e609506aca7c0deae4703b6d1 ]

Jerry Zuo pointed out a rather obscure hotplugging issue that it seems I
accidentally introduced into DRM two years ago.

Pretend we have a topology like this:

|- DP-1: mst_primary
   |- DP-4: active display
   |- DP-5: disconnected
   |- DP-6: active hub
      |- DP-7: active display
      |- DP-8: disconnected
      |- DP-9: disconnected

If we unplug DP-6, the topology starting at DP-7 will be destroyed but
it's payloads will live on in DP-1's VCPI allocations and thus require
removal. However, this removal currently fails because
drm_dp_update_payload_part1() will (rightly so) try to validate the port
before accessing it, fail then abort. If we keep going, eventually we
run the MST hub out of bandwidth and all new allocations will start to
fail (or in my case; all new displays just start flickering a ton).

We could just teach drm_dp_update_payload_part1() not to drop the port
ref in this case, but then we also need to teach
drm_dp_destroy_payload_step1() to do the same thing, then hope no one
ever adds anything to the that requires a validated port reference in
drm_dp_destroy_connector_work(). Kind of sketchy.

So let's go with a more clever solution: any port that
drm_dp_destroy_connector_work() interacts with is guaranteed to still
exist in memory until we say so. While said port might not be valid we
don't really care: that's the whole reason we're destroying it in the
first place! So, teach drm_dp_get_validated_port_ref() to use the all
mighty current_work() function to avoid attempting to validate ports
from the context of mgr->destroy_connector_work. I can't see any
situation where this wouldn't be safe, and this avoids having to play
whack-a-mole in the future of trying to work around port validation.

This doesn't affect runtime because in the current code "idx" is always

First, we read from "vgdev->capsets[idx].max_size" before checking
whether "idx" is within bounds.  And secondly the bounds check is off by
one so we could end up reading one element beyond the end of the

Removing the drm_bridge_remove call should avoid a NULL dereference

taken.

The more natural approach would perhaps be to add a drm_bridge_add,
but there are several other bridges that never call drm_bridge_add.

3579293f6b drm/nouveau/bar/gf100: ensure BAR is mapped
commit 12e08beb32d64b6070b718630490db83dd321c8c upstream.

If the BAR is zero size, it indicates it was never successfully mapped.
Ensure that the BAR is valid during initialization before attempting to
use it.

[ Upstream commit ac2917b01992c098b8d4e6837115e3ca347fdd90 ]

The malidp_mw_connector_helper_funcs is not referenced by name
outside of the file it is in, so make it static to avoid the
following warning:

drivers/gpu/drm/arm/malidp_mw.c:59:41: warning: symbol 'malidp_mw_connector_helper_funcs' was not declared. Should it be static?

afb89cd5f2 drm/i915: Fix use-after-free when destroying GEM context
This patch is a simplified fix to address a use-after-free in 4.14.x and
4.19.x stable kernels. The flaw is already fixed upstream, starting in
5.2, by commit 7dc40713618c ("drm/i915: Introduce a mutex for
file_priv->context_idr") as part of a more complex patch series that
isn't appropriate for backporting to stable kernels.

Expand mutex coverage, while destroying the GEM context, to include the
GEM context lookup step. This fixes a use-after-free detected by KASAN:

dd4f3b3508 drm/i915/gen9: Clear residual context state on context switch
commit bc8a76a152c5f9ef3b48104154a65a68a8b76946 upstream.

Intel ID: PSIRT-TA-201910-001
CVEID: CVE-2019-14615

Intel GPU Hardware prior to Gen11 does not clear EU state
during a context switch. This can result in information
leakage between contexts.

For Gen8 and Gen9, hardware provides a mechanism for
fast cleardown of the EU state, by issuing a PIPE_CONTROL
with bit 27 set. We can use this in a context batch buffer
to explicitly cleardown the state on every context switch.

As this workaround is already in place for gen8, we can borrow
the code verbatim for Gen9.

ba4c2a719e drm/dp_mst: correct the shifting in DP_REMOTE_I2C_READ
commit c4e4fccc5d52d881afaac11d3353265ef4eccb8b upstream.

[Why]
According to DP spec, it should shift left 4 digits for NO_STOP_BIT
in REMOTE_I2C_READ message. Not 5 digits.

In current code, NO_STOP_BIT is always set to zero which means I2C
master is always generating a I2C stop at the end of each I2C write
transaction while handling REMOTE_I2C_READ sideband message. This issue
might have the generated I2C signal not meeting the requirement. Take
random read in I2C for instance, I2C master should generate a repeat
start to start to read data after writing the read address. This issue
will cause the I2C master to generate a stop-start rather than a
re-start which is not expected in I2C random read.

[How]
Correct the shifting value of NO_STOP_BIT for DP_REMOTE_I2C_READ case in
drm_dp_encode_sideband_req().

779f5790fa drm/fb-helper: Round up bits_per_pixel if possible
commit f30e27779d3031a092c2a177b7fb76adccc45241 upstream.

When userspace requests a video mode parameter value that is not
supported, frame buffer device drivers should round it up to a supported
value, if possible, instead of just rejecting it.  This allows
applications to quickly scan for supported video modes.

Currently this rule is not followed for the number of bits per pixel,
causing e.g. "fbset -depth N" to fail, if N is smaller than the current
number of bits per pixel.

Fix this by returning an error only if bits per pixel is too large, and
setting it to the current value otherwise.

See also Documentation/fb/framebuffer.rst, Section 2 (Programmer's View
of /dev/fb*").

845f872f2f drm/sun4i: tcon: Set RGB DCLK min. divider based on hardware model
commit 4396393fb96449c56423fb4b351f76e45a6bcaf6 upstream.

In commit 0b8e7bbde5e7 ("drm/sun4i: tcon: Set min division of TCON0_DCLK
to 1.") it was assumed that all TCON variants support a minimum divider
of 1 if only DCLK was used.

However, the oldest generation of hardware only supports minimum divider
of 4 if only DCLK is used. If a divider of 1 was used on this old
hardware, some scrolling artifact would appear. A divider of 2 seemed
OK, but a divider of 3 had artifacts as well.

Set the minimum divider when outputing to parallel RGB based on the
hardware model, with a minimum of 4 for the oldest (A10/A10s/A13/A20)
hardware, and a minimum of 1 for the rest. A value is not set for the
TCON variants lacking channel 0.

This fixes the scrolling artifacts seen on my A13 tablet.

efa13b328e drm/mst: Fix MST sideband up-reply failure handling
[ Upstream commit d8fd3722207f154b53c80eee2cf4977c3fc25a92 ]

Fix the breakage resulting in the stacktrace below, due to tx queue
being full when trying to send an up-reply. txmsg->seqno is -1 in this
case leading to a corruption of the mstb object by

	txmsg->dst->tx_slots[txmsg->seqno] = NULL;

a128928262 drm/sun4i: hdmi: Remove duplicate cleanup calls
commit 57177d214ee0816c4436c23d6c933ccb32c571f1 upstream.

When the HDMI unbinds drm_connector_cleanup() and drm_encoder_cleanup()
are called. This also happens when the connector and the encoder are
destroyed. This double call triggers a NULL pointer exception.

The patch fixes this by removing the cleanup calls in the unbind
function.

[ Upstream commit 5bf8bec3f4ce044a223c40cbce92590d938f0e9c ]

The hardened usercpy code is too paranoid ever since commit 6a30afa8c1fb
("uaccess: disallow > INT_MAX copy sizes")

Code itself should have been fine as-is.

60dee18d2c drm/nouveau: Move the declaration of struct nouveau_conn_atom up a bit
[ Upstream commit 37a68eab4cd92b507c9e8afd760fdc18e4fecac6 ]

Place the declaration of struct nouveau_conn_atom above that of
struct nouveau_connector. This commit makes no changes to the moved
block what so ever, it just moves it up a bit.

This is a preparation patch to fix some issues with connector handling
on pre nv50 displays (which do not use atomic modesetting).

12fefecbcb drm/amd/display: Fixed kernel panic when booting with DP-to-HDMI dongle
[ Upstream commit a51d9f8fe756beac51ce26ef54195da00a260d13 ]

[Why]
In dc_link_is_dp_sink_present, if dal_ddc_open fails, then
dal_gpio_destroy_ddc is called, destroying pin_data and pin_clock. They
are created only on dc_construct, and next aux access will cause a panic.

[How]
Instead of calling dal_gpio_destroy_ddc, call dal_ddc_close.

[ Upstream commit 3d0e3ce52ce3eb4b9de3caf9c38dbb5a4d3e13c3 ]

The INTERRUPT_CNTL2 register expects a valid DMA address, but is
currently set with a GPU MC address.  This can cause problems on
systems that detect the resulting DMA read from an invalid address
(found on a Power8 guest).

Instead, use the DMA address of the dummy page because it will always
be safe.

The object fence is not set to NULL after its reference is dropped. As a

which may lead to a use after free bug. To avoid the issue, fence is
explicitly set to NULL after dropping its reference.

7b3fe663da drm/amdgpu: disallow direct upload save restore list from gfx driver
[ Upstream commit 58f46d4b65021083ef4b4d49c6e2c58e5783f626 ]

Direct uploading save/restore list via mmio register writes breaks the security
policy. Instead, the driver should pass s&r list to psp.

For all the ASICs that use rlc v2_1 headers, the driver actually upload s&r list
twice, in non-psp ucode front door loading phase and gfx pg initialization phase.
The latter is not allowed.

VG12 is the only exception where the driver still keeps legacy approach for S&R
list uploading. In theory, this can be elimnated if we have valid srcntl ucode
for VG12.

[ Upstream commit b78e70c04c149299bd210759d7c7af7c86b89ca8 ]

Currently when the gather buffers are copied, they are copied to a
buffer that is allocated for the host1x client that wants to execute the
command streams in the buffers. However, the gather buffers will be read
by the host1x device, which causes SMMU faults if the DMA API is backed
by an IOMMU.

Fix this by allocating the gather buffer copy for the host1x device,
which makes sure that it will be mapped into the host1x's IOVA space if
the DMA API is backed by an IOMMU.

327e41607b drm/bridge: dw-hdmi: Restore audio when setting a mode
[ Upstream commit fadfee3f9d8f114435a8a3e9f83a227600d89de7 ]

When setting a new display mode, dw_hdmi_setup() calls
dw_hdmi_enable_video_path(), which disables all hdmi clocks, including
the audio clock.

We should only (re-)enable the audio clock if audio was already enabled
when setting the new mode.

Without this patch, on RK3288, there will be HDMI audio on some monitors
if i2s was played to headphone when the monitor was plugged.
ACER H277HU and ASUS PB278 are two of the monitors showing this issue.

[ Upstream commit dd998291dbe92106d8c4a7581c409b356928d711 ]

[WHY]

During detection:
function: get_active_converter_info populates link->dpcd_caps.dongle_caps
only when dpcd_rev >= DPCD_REV_11 and DWN_STRM_PORTX_TYPE is
DOWN_STREAM_DETAILED_HDMI or DOWN_STREAM_DETAILED_DP_PLUS_PLUS.
Otherwise, it is not cleared, and stale information remains.

During mode validation:
function: dp_active_dongle_validate_timing reads
link->dpcd_caps.dongle_caps->dongle_type to determine the maximum
pixel clock to support. This information is now stale and no longer
valid.

[HOW]
dp_active_dongle_validate_timing should be using
link->dpcd_caps->dongle_type instead.

5d60d39814 drm/drm_vblank: Change EINVAL by the correct errno
[ Upstream commit aed6105b28b10613f16c0bfe97525fe5a23338df ]

For historical reasons, the function drm_wait_vblank_ioctl always return
-EINVAL if something gets wrong. This scenario limits the flexibility
for the userspace to make detailed verification of any problem and take
some action. In particular, the validation of “if (!dev->irq_enabled)”
in the drm_wait_vblank_ioctl is responsible for checking if the driver
support vblank or not. If the driver does not support VBlank, the
function drm_wait_vblank_ioctl returns EINVAL, which does not represent
the real issue; this patch changes this behavior by return EOPNOTSUPP.
Additionally, drm_crtc_get_sequence_ioctl and
drm_crtc_queue_sequence_ioctl, also returns EINVAL if vblank is not
supported; this patch also changes the return value to EOPNOTSUPP in
these functions. Lastly, these functions are invoked by libdrm, which is
used by many compositors; because of this, it is important to check if
this change breaks any compositor. In this sense, the following projects
were examined:

* Drm-hwcomposer
* Kwin
* Sway
* Wlroots
* Wayland
* Weston
* Mutter
* Xorg (67 different drivers)

For each repository the verification happened in three steps:

* Update the main branch
* Look for any occurrence of "drmCrtcQueueSequence",
  "drmCrtcGetSequence", and "drmWaitVBlank" with the command git grep -n
  "STRING".
* Look in the git history of the project with the command
git log -S<STRING>

None of the above projects validate the use of EINVAL when using
drmWaitVBlank(), which make safe, at least for these projects, to change
the return values. On the other hand, mesa and xserver project uses
drmCrtcQueueSequence() and drmCrtcGetSequence(); this change is harmless
for both projects.

Change since V5 (Pekka Paalanen):
 - Check if the change also affects Mutter

Change since V4 (Daniel):
 - Also return EOPNOTSUPP in drm_crtc_[get|queue]_sequence_ioctl

Change since V3:
 - Return EINVAL for _DRM_VBLANK_SIGNAL (Daniel)

Change since V2:
 Daniel Vetter and Chris Wilson
 - Replace ENOTTY by EOPNOTSUPP
 - Return EINVAL if the parameters are wrong

[ Upstream commit bee447e224b2645911c5d06e35dc90d8433fcef6 ]

The DDC/CI protocol involves sending a multi-byte request to the
display via I2C, which is typically followed by a multi-byte
response. The internal I2C controller only allows single byte
reads/writes or reads of 8 sequential bytes, hence DDC/CI is not
supported when the internal I2C controller is used. The I2C
transfers complete without errors, however the data in the response
is garbage. Abort transfers to/from slave address 0x37 (DDC) with
-EOPNOTSUPP, to make it evident that the communication is failing.

a14083fe26 drm: meson: venc: cvbs: fix CVBS mode matching
commit 43cb86799ff03e9819c07f37f72f80f8246ad7ed upstream.

With commit 222ec1618c ("drm: Add aspect ratio parsing in DRM
layer") the drm core started honoring the picture_aspect_ratio field
when comparing two drm_display_modes. Prior to that it was ignored.
When the CVBS encoder driver was initially submitted there was no aspect
ratio check.

Switch from drm_mode_equal() to drm_mode_match() without
DRM_MODE_MATCH_ASPECT_RATIO to fix "kmscube" and X.org output using the
CVBS connector. When (for example) kmscube sets the output mode when
using the CVBS connector it passes HDMI_PICTURE_ASPECT_NONE, making the
drm_mode_equal() fail as it include the aspect ratio.

Prior to this patch kmscube reported:
  failed to set mode: Invalid argument

The CVBS mode checking in the sun4i (drivers/gpu/drm/sun4i/sun4i_tv.c
sun4i_tv_mode_to_drm_mode) and ZTE (drivers/gpu/drm/zte/zx_tvenc.c
tvenc_mode_{pal,ntsc}) drivers don't set the "picture_aspect_ratio" at
all. The Meson VPU driver does not rely on the aspect ratio for the CVBS
output so we can safely decouple it from the hdmi_picture_aspect
setting.

commit 4f69851fbaa26b155330be35ce8ac393e93e7442 upstream.

The "used" variables here come from the user in the ioctl and it can be
negative.  It could result in an out of bounds write.

8e47f51af8 drm/msm: fix memleak on release
commit a64fc11b9a520c55ca34d82e5ca32274f49b6b15 upstream.

If a process is interrupted while accessing the "gpu" debugfs file and
the drm device struct_mutex is contended, release() could return early
and fail to free related resources.

Note that the return value from release() is ignored.

The number of syncpoints on Tegra186 is 576 and therefore no longer fits
into 8 bits. Increase the size of the syncpoint ID field to 10 in order
to accomodate all syncpoints.

15479dd156 drm/sun4i: tcon: Set min division of TCON0_DCLK to 1.
[ Upstream commit 0b8e7bbde5e7e2c419567e1ee29587dae3b78ee3 ]

The datasheet of V3s (and various other chips) wrote
that TCON0_DCLK_DIV can be >= 1 if only dclk is used,
and must >= 6 if dclk1 or dclk2 is used. As currently
neither dclk1 nor dclk2 is used (no writes to these
bits), let's set minimal division to 1.

If this minimal division is 6, some common dot clock
frequencies can't be produced (e.g. 30MHz will not be
possible and will fallback to 25MHz), which is
obviously not an expected behaviour.

f0f4fa94ab UPSTREAM: drm/client: remove the exporting of drm_client_close
The function drm_client_close is declared as static and marked as
EXPORT_SYMBOL. It's a bit confusing for an internal function to be
exported. The area of visibility for such function is its .c file
and all other modules. Other *.c files of the same module can't use it,
despite all other modules can. Relying on the fact that this is the
internal function and it's not a crucial part of the API, the patch
removes the EXPORT_SYMBOL marking of drm_client_close.

7d9566fb14 gpu: ipu-v3: pre: don't trigger update if buffer address doesn't change
[ Upstream commit eb0200a4357da100064971689d3a0e9e3cf57f33 ]

On a NOP double buffer update where current buffer address is the same
as the next buffer address, the SDW_UPDATE bit clears too late. As we
are now using this bit to determine when it is safe to signal flip
completion to userspace this will delay completion of atomic commits
where one plane doesn't change the buffer by a whole frame period.

Fix this by remembering the last buffer address and just skip the
double buffer update if it would not change the buffer address.

e80e88ef60 drm/i915/userptr: Try to acquire the page lock around set_page_dirty()
commit 2d691aeca4aecbb8d0414a777a46981a8e142b05 upstream.

set_page_dirty says:

	For pages with a mapping this should be done under the page lock
	for the benefit of asynchronous memory errors who prefer a
	consistent dirty state. This rule can be broken in some special
	cases, but should be better not to.

Under those rules, it is only safe for us to use the plain set_page_dirty
calls for shmemfs/anonymous memory. Userptr may be used with real
mappings and so needs to use the locked version (set_page_dirty_lock).

However, following a try_to_unmap() we may want to remove the userptr and
so call put_pages(). However, try_to_unmap() acquires the page lock and
so we must avoid recursively locking the pages ourselves -- which means
that we cannot safely acquire the lock around set_page_dirty(). Since we
can't be sure of the lock, we have to risk skip dirtying the page, or
else risk calling set_page_dirty() without a lock and so risk fs
corruption.

a0ee03bb52 drm/i915/pmu: "Frequency" is reported as accumulated cycles
commit add3eeed3683e2636ef524db48e1a678757c8e96 upstream.

We report "frequencies" (actual-frequency, requested-frequency) as the
number of accumulated cycles so that the average frequency over that
period may be determined by the user. This means the units we report to
the user are Mcycles (or just M), not MHz.

3d0c72f99e msm/gpu/a6xx: Force of_dma_configure to setup DMA for GMU
[ Upstream commit 32aa27e15c28d3898ed6f9b3c98f95f34a81eab2 ]

The point of the 'force_dma' parameter for of_dma_configure
is to force the device to be set up even if DMA capability is
not described by the firmware which is exactly the use case
 we have for GMU - we need SMMU to get set up but we have no
other dma capabilities since memory is managed by the GPU
driver. Currently we pass false so of_dma_configure() fails
and subsequently GMU and GPU probe does as well.

4d146d7268 qxl: fix null-pointer crash during suspend
[ Upstream commit 7948a2b15873319d1bff4d37c09b9f2bf87b9021 ]

"crtc->helper_private" is not initialized by the QXL driver and thus the
"crtc_funcs->disable" call would crash (resulting in suspend failure).
Fix this by converting the suspend/resume functions to use the
drm_mode_config_helper_* helpers.

Tested system sleep with QEMU 3.0 using "echo mem > /sys/power/state".
During suspend the following message is visible from QEMU:

    spice/server/display-channel.c:2425:display_channel_validate_surface: canvas address is 0x7fd05da68308 for 0 (and is NULL)
    spice/server/display-channel.c:2426:display_channel_validate_surface: failed on 0

This seems to be triggered by QXL_IO_NOTIFY_CMD after
QXL_IO_DESTROY_PRIMARY_ASYNC, but aside from the warning things still
seem to work (tested with both the GTK and -spice options).

fee619bb81 drm/i915/cmdparser: Fix jump whitelist clearing
commit ea0b163b13ffc52818c079adb00d55e227a6da6f upstream.

When a jump_whitelist bitmap is reused, it needs to be cleared.
Currently this is done with memset() and the size calculation assumes
bitmaps are made of 32-bit words, not longs.  So on 64-bit
architectures, only the first half of the bitmap is cleared.

If some whitelist bits are carried over between successive batches
submitted on the same context, this will presumably allow embedding
the rogue instructions that we're trying to reject.

Use bitmap_zero() instead, which gets the calculation right.

commit 7e34f4e4aad3fd34c02b294a3cf2321adf5b4438 upstream.

In some circumstances the RC6 context can get corrupted. We can detect

The HW recovers from the corrupted state after a system suspend/resume
cycle, so detect the recovery and re-enable RC6 and runtime PM.

011b7173cb drm/i915: Lower RM timeout to avoid DSI hard hangs
commit 1d85a299c4db57c55e0229615132c964d17aa765 upstream.

In BXT/APL, device 2 MMIO reads from MIPI controller requires its PLL
to be turned ON. When MIPI PLL is turned off (MIPI Display is not
active or connected), and someone (host or GT engine) tries to read
MIPI registers, it causes hard hang. This is a hardware restriction
or limitation.

Driver by itself doesn't read MIPI registers when MIPI display is off.
But any userspace application can submit unprivileged batch buffer for
execution. In that batch buffer there can be mmio reads. And these
reads are allowed even for unprivileged applications. If these
register reads are for MIPI DSI controller and MIPI display is not
active during that time, then the MMIO read operation causes system
hard hang and only way to recover is hard reboot. A genuine
process/application won't submit batch buffer like this and doesn't
cause any issue. But on a compromised system, a malign userspace
process/app can generate such batch buffer and can trigger system
hard hang (denial of service attack).

The fix is to lower the internal MMIO timeout value to an optimum
value of 950us as recommended by hardware team. If the timeout is
beyond 1ms (which will hit for any value we choose if MMIO READ on a
DSI specific register is performed without PLL ON), it causes the
system hang. But if the timeout value is lower than it will be below
the threshold (even if timeout happens) and system will not get into
a hung state. This will avoid a system hang without losing any
programming or GT interrupts, taking the worst case of lowest CDCLK
frequency and early DC5 abort into account.

a7bda639a1 drm/i915/cmdparser: Ignore Length operands during command matching
commit 926abff21a8f29ef159a3ac893b05c6e50e043c3 upstream.

Some of the gen instruction macros (e.g. MI_DISPLAY_FLIP) have the
length directly encoded in them. Since these are used directly in
the tables, the Length becomes part of the comparison used for
matching during parsing. Thus, if the cmd being parsed has a
different length to that in the table, it is not matched and the
cmd is accepted via the default variable length path.

Fix by masking out everything except the Opcode in the cmd tables

6e53c71a69 drm/i915/cmdparser: Add support for backward jumps
commit f8c08d8faee5567803c8c533865296ca30286bbf upstream.

To keep things manageable, the pre-gen9 cmdparser does not
attempt to track any form of nested BB_START's. This did not
prevent usermode from using nested starts, or even chained
batches because the cmdparser is not strictly enforced pre gen9.

Instead, the existence of a nested BB_START would cause the batch
to be emitted in insecure mode, and any privileged capabilities
would not be available.

For Gen9, the cmdparser becomes mandatory (for BCS at least), and
so not providing any form of nested BB_START support becomes
overly restrictive. Any such batch will simply not run.

We make heavy use of backward jumps in igt, and it is much easier
to add support for this restricted subset of nested jumps, than to
rewrite the whole of our test suite to avoid them.

Add the required logic to support limited backward jumps, to
instructions that have already been validated by the parser.

Note that it's not sufficient to simply approve any BB_START
that jumps backwards in the buffer because this would allow an
attacker to embed a rogue instruction sequence within the
operand words of a harmless instruction (say LRI) and jump to
that.

We introduce a bit array to track every instr offset successfully
validated, and test the target of BB_START against this. If the
target offset hits, it is re-written to the same offset in the
shadow buffer and the BB_START cmd is allowed.

Note: This patch deliberately ignores checkpatch issues in the
cmdtables, in order to match the style of the surrounding code.
We'll correct the entire file in one go in a later patch.

Refactor all error conditions to jump to a dedicated

cdd77c6b4b drm/i915: Add gen9 BCS cmdparsing
commit 0f2f39758341df70202ae1c42d5a1e4ee392b6d3 upstream.

For gen9 we enable cmdparsing on the BCS ring, specifically
to catch inadvertent accesses to sensitive registers

Unlike gen7/hsw, we use the parser only to block certain
registers. We can rely on h/w to block restricted commands,
so the command tables only provide enough info to allow the
parser to delineate each command, and identify commands that
access registers.

Note: This patch deliberately ignores checkpatch issues in
favour of matching the style of the surrounding code. We'll
correct the entire file in one go in a later patch.

fea688c5dd drm/i915: Allow parsing of unsized batches
commit 435e8fc059dbe0eec823a75c22da2972390ba9e0 upstream.

In "drm/i915: Add support for mandatory cmdparsing" we introduced the
concept of mandatory parsing. This allows the cmdparser to be invoked
even when user passes batch_len=0 to the execbuf ioctl's.

However, the cmdparser needs to know the extents of the buffer being
scanned. Refactor the code to ensure the cmdparser uses the actual
object size, instead of the incoming length, if user passes 0.

7ce726b61c drm/i915: Support ro ppgtt mapped cmdparser shadow buffers
commit 4f7af1948abcb18b4772fe1bcd84d7d27d96258c upstream.

For Gen7, the original cmdparser motive was to permit limited
use of register read/write instructions in unprivileged BB's.
This worked by copying the user supplied bb to a kmd owned
bb, and running it in secure mode, from the ggtt, only if
the scanner finds no unsafe commands or registers.

For Gen8+ we can't use this same technique because running bb's
from the ggtt also disables access to ppgtt space. But we also
do not actually require 'secure' execution since we are only
trying to reduce the available command/register set. Instead we
will copy the user buffer to a kmd owned read-only bb in ppgtt,
and run in the usual non-secure mode.

Note that ro pages are only supported by ppgtt (not ggtt), but
luckily that's exactly what we need.

Add the required paths to map the shadow buffer to ppgtt ro for Gen8+

fc3510fe6f drm/i915: Add support for mandatory cmdparsing
commit 311a50e76a33d1e029563c24b2ff6db0c02b5afe upstream.

The existing cmdparser for gen7 can be bypassed by specifying
batch_len=0 in the execbuf call. This is safe because bypassing
simply reduces the cmd-set available.

In a later patch we will introduce cmdparsing for gen9, as a
security measure, which must be strictly enforced since without
it we are vulnerable to DoS attacks.

Introduce the concept of 'required' cmd parsing that cannot be
bypassed by submitting zero-length bb's.

commit 44157641d448cbc0c4b73c5231d2b911f0cb0427 upstream.

Retroactively stop reporting support for secure batches
through the api for gen6+ so that older binaries trigger
the fallback path instead.

Older binaries use secure batches pre gen6 to access resources
that are not available to normal usermode processes. However,
all known userspace explicitly checks for HAS_SECURE_BATCHES
before relying on the secure batch feature.

Since there are no known binaries relying on this for newer gens
we can kill secure batches from gen6, via I915_PARAM_HAS_SECURE_BATCHES.

fd9a708c7b drm/amdgpu/powerplay/vega10: allow undervolting in p7
commit e6f4e274c1e52d1f0bfe293fb44ddf59de6c0374 upstream.

The vega10_odn_update_soc_table() function does not allow the SCLK
dependent voltage to be set for power-state 7 to a value below the default
in pptable. Change the for-loop condition to allow undervolting in the
highest state.

11377c3e99 drm/ttm: Restore ttm prefaulting
commit 941f2f72dbbe0cf8c2d6e0b180a8021a0ec477fa upstream.

Commit 4daa4fba3a ("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.

Do not try to allocate any amount of memory requested by the user.
Instead limit it to 128 registers. Actually the longest series of
consecutive allowed registers are 48, mmGB_TILE_MODE0-31 and
mmGB_MACROTILE_MODE0-15 (0x2644-0x2673).

commit 0a3242bdb47713e09cb004a0ba4947d3edf82d8a upstream.

when creating a vGPU workload, the guest context head pointer should
be updated correctly by comparing with the exsiting workload in the
guest worklod queue including the current running context.

in some situation, there is a running context A and then received 2 new
vGPU workload context B and A. in the new workload context A, it's head
pointer should be updated with the running context A's tail.

v2: walk through guest workload list in backward way.

198bc7040c drm/nouveau/kms/nv50-: Don't create MSTMs for eDP connectors
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.

7a85c86735 drm/msm/dsi: Fix return value check for clk_get_parent
commit 5fb9b797d5ccf311ae4aba69e86080d47668b5f7 upstream.

clk_get_parent returns an error pointer upon failure, not NULL. So the
checks as they exist won't catch a failure. This patch changes the
checks and the return values to properly handle an error pointer.

0e45633f49 drm/omap: fix max fclk divider for omap36xx
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.

d224d76f24 UPSTREAM: drm/radeon: untag user pointers in radeon_gem_userptr_ioctl
(Upstream commit 4fdfae8d8f855d79b7d83fcd590b6ac7ed0099cf).

This patch is a part of a series that extends kernel ABI to allow to pass
tagged user pointers (with the top byte set to something else other than
0x00) as syscall arguments.

In radeon_gem_userptr_ioctl() an MMU notifier is set up with a (tagged)
userspace pointer.  The untagged address should be used so that MMU
notifiers for the untagged address get correctly matched up with the right
BO.  This funcation also calls radeon_ttm_tt_pin_userptr(), which uses
provided user pointers for vma lookups, which can only by done with
untagged pointers.

This patch untags user pointers in radeon_gem_userptr_ioctl().

d775d452c6 BACKPORT: drm/amdgpu: untag user pointers
(Upstream commit 35f3fc87bebfb2fffc1a9cdaf661ee3f95c2a5f1).

This patch is a part of a series that extends kernel ABI to allow to pass
tagged user pointers (with the top byte set to something else other than
0x00) as syscall arguments.

In amdgpu_gem_userptr_ioctl() and amdgpu_amdkfd_gpuvm.c/init_user_pages()
an MMU notifier is set up with a (tagged) userspace pointer.  The untagged
address should be used so that MMU notifiers for the untagged address get
correctly matched up with the right BO.  This patch untag user pointers in
amdgpu_gem_userptr_ioctl() for the GEM case and in amdgpu_amdkfd_gpuvm_
alloc_memory_of_gpu() for the KFD case.  This also makes sure that an
untagged pointer is passed to amdgpu_ttm_tt_get_user_pages(), which uses
it for vma lookups.
