855e764d39 drm/panel-simple: Fix dotclock for Ortustech COM37H3M
The currently listed dotclock disagrees with the currently
listed vrefresh rate. Change the dotclock to match the vrefresh.

There are two variants of the COM37H3M panel.
The older one's COM37H3M05DTC data sheet specifies:

                         MIN      TYP     MAX
CLK frequency    fCLK     --       22.4    26.3 MHz (in VGA mode)
VSYNC Frequency  fVSYNC   54       60      66   Hz
VSYNC cycle time tv       --      650      --   H
HSYNC frequency  fHSYNC   --       39.3    --   kHz
HSYNC cycle time th       --      570      --   CLK

The newer one's COM37H3M99DTC data sheet says:

                         MIN      TYP     MAX
CLK frequency    fCLK     18       19.8    27   MHz
VSYNC Frequency  fVSYNC   54       60      66   Hz
VSYNC cycle time tv      646      650     700   H
HSYNC frequency  fHSYNC  --        39.0    50.0 kHz
HSYNC cycle time th      504      508     630   CLK

So we choose a parameter set that lies within the specs
of both variants. We start at .vrefresh = 60,
choose .htotal = 570 and .vtotal = 650 and end up
in a clock of 22.230 MHz.

798fa870ab drm/i915: Improve the start alignment of bonded pairs
Always wait on the start of the signaler request to reduce the problem
of dequeueing the bonded pair too early -- we want both payloads to
start at the same time, with no latency, and yet still allow others to
make full use of the slack in the system. This reduce the amount of time
we spend waiting on the semaphore used to synchronise the start of the
bonded payload.

0d1650fa24 drm/mm: Remove redundant assignment in drm_mm_reserve_node
In Pete Goodliffe words, "You can improve a system by adding new code. You
can also improve a system by removing code" - In this case, commit
"202b52b7fbf70" added new code to initialize end of the node. So, there
is no need for duplicated initialization, and this patch simply removes it.

8496a2172d drm/meson: Add YUV420 output support
This patch adds support for the YUV420 output from the Amlogic Meson SoCs
Video Processing Unit to the HDMI Controller.

The YUV420 is obtained by generating a YUV444 pixel stream like
the classic HDMI display modes, but then the Video Encoder output
can be configured to down-sample the YUV444 pixel stream to a YUV420
stream.
In addition if pixel stream down-sampling, the Y Cb Cr components must
also be mapped differently to align with the HDMI2.0 specifications.

This mode needs a different clock generation scheme since the TMDS PHY
clock must match the 10x ratio with the YUV420 pixel clock, but
the video encoder must run at 2x the pixel clock.

This patch enables the bridge bus format negociation, and handles
the YUV420 case if selected by the negociation.

gmbus/aux may be clocked by cdclk, thus we should make sure no

the lock ordering here shouldn't matter.

Problem Description:
Currently we are checking internal fused rev id with pci rev id. However, fused
internal rev id is the same on all raven2 parts (in which Dali and Pollock were
based on too), thus Pollock detection fails

Fix:
use the pci rev to preform the detection for bandwidth calculations.

a0e40018dc drm/amd/display: Stop if retimer is not available
Raven provides retimer feature support that requires i2c interaction in
order to make it work well, all settings required for this configuration
are loaded from the Atom bios which include the i2c address. If the
retimer feature is not available, we should abort the attempt to set
this feature, otherwise, it makes the following line return
I2C_CHANNEL_OPERATION_NO_RESPONSE:

 i2c_success = i2c_write(pipe_ctx, slave_address, buffer, sizeof(buffer));
 ...
 if (!i2c_success)
   ASSERT(i2c_success);

This ends up causing problems with hotplugging HDMI displays on Raven,
and causes retimer settings to warn like so:

This commit reworks the way that we handle i2c write for retimer in the
way that we abort this configuration if the feature is not available in
the device. For debug sake, we kept a simple log message in case the
retimer is not available.

1450d23783 drm/amd/display: fix a minor HDCP logging error
[why]
In HDCP Uninitialzed State, a CPIRQ event would cause log output
internal policy error because the CPIRQ event is not recognized as
unexpected event.

[how]
CPIRQ is issued in HDCP uninitialized state is unexpected.  We should
set unexpected event flag in event ctx.

d7ecf5e37d drm/amd/display: determine rx id list bytes to read based on device count
[why]
Some RX doesn't like us to read rx id list upto max rx id list size.  As
discussed, we decided to read rx id list based on device count.

[how]
According to HDCP specs the actual size of rx id list is calculated as
rx id list size = 2+3+16+5*device_count.  We will read 16 bytes at a
time until it reached or exceeded rx id list size.

8cc426d79b drm/amd/display: Program DSC during timing programming
[why]
Link or DIG BE can't be exposed to a higher stream bandwidth than they
can handle. When DSC is required to fit the stream into the link
bandwidth, DSC has to be programmed during timing programming to ensure
this. Without it, intermittent issues such as black screen after S3 or a
hot-plug can be seen.

[how]
Move DSC programming from enabling stream on link to timing setup.

4c631826e0 drm/amd/display: Not check wm and clk change flag in optimized bandwidth.
[Why]
System isn't able to enter S0i3 due to not send display count 0 to smu.
When dpms off, clk changed flag is cleared alreay, and it is checked
when doing optimized bandwidth, and update clocks is bypassed due to the
flag is unset.

[How]
Remove check flag incide the function since watermark values and clocks
values are checked during update to determine whether to perform it, no
need to check it again outside the function.

It is possible even if sink signal is MST but driver enables SST stream.
We should not determine if we should do MST authentication based on

The UNSLICE_UNIT_LEVEL_CLKGATE and UNSLICE_UNIT_LEVEL_CLKGATE2 registers
that we update in a few engine workarounds are not masked registers
(i.e., we don't have to write a mask bit in the top 16 bits when
updating one of the lower 16 bits).  As such, these workarounds should
be applied via wa_write_or() rather than wa_masked_en()

v2:
 - Rebase

cc328351e1 drm/i915/gt: Wait for the wa batch to be pinned
Be sure to wait for the vma to be in place before we tell the GPU to
execute from the wa batch. Since initialisation is mostly synchronous
(or rather at some point during start up we will need to sync anyway),
we can affort to do an explicit i915_vma_sync() during wa batch
construction rather than check for a required await on every context
switch. (We don't expect to change the wa bb at run time so paying the
cost once up front seems preferrable.)

afdd597940 drm/vboxvideo/vboxvideo.h: Replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

270810a732 drm/i915/hotplug: Use phy to get the hpd_pin instead of the port (v5)
On some platforms such as Elkhart Lake, although we may use DDI D
to drive a connector, we have to use PHY A (Combo Phy PORT A) to
detect the hotplug interrupts as per the spec because there is no
one-to-one mapping between DDIs and PHYs. Therefore, use the
function intel_port_to_phy() which contains the logic for such
mapping(s) to find the correct hpd_pin.

This change should not affect other platforms as there is always
a one-to-one mapping between DDIs and PHYs.

v2:
- Convert the case statements to use PHYs instead of PORTs (Jani)

v3:
- Refactor the function to reduce the number of return statements by
  lumping all the case statements together except PHY_F which needs
  special handling (Jose)

v4:
- Add a comment describing how the HPD pin value associated with any
  port can be retrieved using port or phy enum value. (Jani)

v5:
- Use case ranges instead of individual labels and also normalize the
  return statement by adding -PHY_A to the expression (Ville)

7be1b9b8e9 drm/mm: Break long searches in fragmented address spaces
We try hard to select a suitable hole in the drm_mm first time. But if
that is unsuccessful, we then have to look at neighbouring nodes, and
this requires traversing the rbtree. Walking the rbtree can be slow
(much slower than a linear list for deep trees), and if the drm_mm has
been purposefully fragmented our search can be trapped for a long, long
time. For non-preemptible kernels, we need to break up long CPU bound
sections by manually checking for cond_resched(); similarly we should
also bail out if we have been told to terminate. (In an ideal world, we
would break for any signal, but we need to trade off having to perform
the search again after ERESTARTSYS, which again may form a trap of
making no forward progress.)

5b2adbddf2 drm/vc4/vc4_drv.h: Replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

ee2413eeed drm/i915: Add mechanism to submit a context WA on ring submission
This patch adds framework to submit an arbitrary batchbuffer on each
context switch to clear residual state for render engine on Gen7/7.5
devices.

The idea of always emitting the context and vm setup around each request
is primary to make reset recovery easy, and not require rewriting the
ringbuffer. As each request would set up its own context, leaving it to
the HW to notice and elide no-op context switches, we could restart the
ring at any point, and reorder the requests freely.

However, to avoid emitting clear_residuals() between consecutive requests
in the ringbuffer of the same context, we do want to track the current
context in the ring. In doing so, we need to be careful to only record a
context switch when we are sure the next request will be emitted.

This security mitigation change does not trigger any performance
regression. Performance is on par with current mainline/drm-tip.

v2: Update vm_alias params to point to correct address space "vm" due to

135dde8853 drm/i915/gvt: Fix dma-buf display blur issue on CFL
Commit c3b5a8430d ("drm/i915/gvt: Enable gfx virtualiztion for CFL")
added the support on CFL. The vgpu emulation hotplug support on CFL was
supposed to be included in that patch. Without the vgpu emulation
hotplug support, the dma-buf based display gives us a blur face.

So fix this issue by adding the vgpu emulation hotplug support on CFL.

09ed6ba43e drm/amdgpu/display: navi1x copy dcn watermark clock settings to smu resume from s3 (v2)
This interface is for dGPU Navi1x. Linux dc-pplib interface depends
 on window driver dc implementation.

 For Navi1x, clock settings of dcn watermarks are fixed. the settings
 should be passed to smu during boot up and resume from s3.
 boot up: dc calculate dcn watermark clock settings within dc_create,
 dcn20_resource_construct, then call pplib functions below to pass
 the settings to smu:
 smu_set_watermarks_for_clock_ranges
 smu_set_watermarks_table
 navi10_set_watermarks_table
 smu_write_watermarks_table

 For Renoir, clock settings of dcn watermark are also fixed values.
 dc has implemented different flow for window driver:
 dc_hardware_init / dc_set_power_state
 dcn10_init_hw
 notify_wm_ranges
 set_wm_ranges

 For Linux
 smu_set_watermarks_for_clock_ranges
 renoir_set_watermarks_table
 smu_write_watermarks_table

 dc_hardware_init -> amdgpu_dm_init
 dc_set_power_state --> dm_resume

 therefore, linux dc-pplib interface of navi10/12/14 is different
 from that of Renoir.

a0275dfc82 drm/amd/display: fix dcc swath size calculations on dcn1
[Why]
Swath sizes are being calculated incorrectly. The horizontal swath size
should be the product of block height, viewport width, and bytes per
element, but the calculation uses viewport height instead of width. The
vertical swath size is similarly incorrectly calculated. The effect of
this is that we report the wrong DCC caps.

[How]
Use viewport width in the horizontal swath size calculation and viewport
height in the vertical swath size calculation.

when we disable MST we should clear the cur link settings (lane_count=0 is

23baedd217 drm/i915: Don't check for wm changes until we've compute the wms fully
Currently we're comparing the watermarks between the old and new states
before we've fully computed the new watermarks. In particular
skl_build_pipe_wm() will not account for the amount of ddb space we'll
have. That information is only available during skl_compute_ddb()
which will proceed to zero out any watermark level exceeding the
ddb allocation. If we're short on ddb space this will end up
adding the plane to the state due erronously determining that the
watermarks have changed. Fix the problem by deferring
skl_wm_add_affected_planes() until we have the final watermarks
computed.

Noticed this when trying enable transition watermarks on glk.
We now computed the trans_wm as 28, but we only had 14 blocks
of ddb, and thus skl_compute_ddb() ended up disabling the cursor
trans_wm every time. Thus we ended up adding the cursor to every
commit that didn't actually affect the cursor at all.

e7f54e6c19 drm/i915: Don't check uv_wm in skl_plane_wm_equals()
The hardware never sees the uv_wm values (apart from
uv_wm.min_ddb_alloc affecting the ddb allocation). Thus there
is no point in comparing uv_wm to determine if we need to
reprogram the watermark registers. So let's check only the
rgb/y watermark in skl_plane_wm_equals(). But let's leave
a comment behind so that the next person reading this doesn't
get as confused as I did when I added this check.

If the ddb allocation ends up changing due to uv_wm
skl_ddb_add_affected_planes() takes care of adding the plane
to the state.

TODO: we should perhaps just eliminate uv_wm from the state
and simply track the min_ddb_alloc for uv instead.

9daee6141c drm/v3d: Replace wait_for macros to remove use of msleep
The wait_for macro's for Broadcom V3D driver used msleep, which is
inappropriate due to its inaccuracy at low values (minimum wait time
is about 30ms on the Raspberry Pi).  This sleep was triggering in
v3d_clean_caches(), causing us to only be able to dispatch ~33 compute
jobs per second.

This patch replaces the macro with the one from the Intel i915 version
which uses usleep_range to provide more accurate waits.

9340dfd3f5 drm/amdgpu/display: navi1x copy dcn watermark clock settings to smu resume from s3 (v2)
This interface is for dGPU Navi1x. Linux dc-pplib interface depends
 on window driver dc implementation.

 For Navi1x, clock settings of dcn watermarks are fixed. the settings
 should be passed to smu during boot up and resume from s3.
 boot up: dc calculate dcn watermark clock settings within dc_create,
 dcn20_resource_construct, then call pplib functions below to pass
 the settings to smu:
 smu_set_watermarks_for_clock_ranges
 smu_set_watermarks_table
 navi10_set_watermarks_table
 smu_write_watermarks_table

 For Renoir, clock settings of dcn watermark are also fixed values.
 dc has implemented different flow for window driver:
 dc_hardware_init / dc_set_power_state
 dcn10_init_hw
 notify_wm_ranges
 set_wm_ranges

 For Linux
 smu_set_watermarks_for_clock_ranges
 renoir_set_watermarks_table
 smu_write_watermarks_table

 dc_hardware_init -> amdgpu_dm_init
 dc_set_power_state --> dm_resume

 therefore, linux dc-pplib interface of navi10/12/14 is different
 from that of Renoir.

v2: add missing unlock in error case

f9b9b6d972 drm/amd/display: fix dcc swath size calculations on dcn1
[Why]
Swath sizes are being calculated incorrectly. The horizontal swath size
should be the product of block height, viewport width, and bytes per
element, but the calculation uses viewport height instead of width. The
vertical swath size is similarly incorrectly calculated. The effect of
this is that we report the wrong DCC caps.

Use viewport width in the horizontal swath size calculation and viewport
height in the vertical swath size calculation.

df8e34ac27 drm/amd/display: fix image corruption with ODM 2:1 DSC 2 slice
[why]
When combining two or more pipes in DSC mode, there will always be more
than 1 slice per line.  In this case, as per DSC rules, the sink device
is expecting that the ICH is reset at the end of each slice line (i.e.
ICH_RESET_AT_END_OF_LINE must be configured based on the number of
slices at the output of ODM).  It is recommended that software set
ICH_RESET_AT_END_OF_LINE = 0xF for each DSC in the ODM combine.  However
the current code only set ICH_RESET_AT_END_OF_LINE = 0xF when number of
slice per DSC engine is greater than 1 instead of number of slice per
output after ODM combine.

[how]
Add is_odm in dsc config. Set ICH_RESET_AT_END_OF_LINE = 0xF if either
is_odm or number of slice per DSC engine is greater than 1.

8d8c82b699 drm/amd/display: add worst case dcc meta pitch to fake plane
[why]
When we have single channel memory, we can not light up 2 4k displays
with a 1080p edp, because we don't have enough bw by a small margin.
this small margin comes from dcc meta being too large. We however don't
have this dcc meta when we create fake planes so, before the flip we
will not filter out the mode for 2 4k displays with a 1080p edp

[how]
Change get_default_swizzle_mode to something more general so we don't
end up with a separate function for every missing field in the fake
plane. Add a reasonable dcc meta to the fake plane when it is filled in,
so we filter out modes that don't have enough bandwidth. To do this, we
take the screen width and align it to 1024(8k 60)

8f1e574090 drm/i915: Add invert-brightness quirk for Thundersoft TST178 tablet
The Thundersoft TST178 tablet uses a DSI panel with an external PWM
controller (as all DSI panels do). But unlike other DSI panels a duty-cycle
of 100% turns the backlight off and 0% sets it to maximum brightness.

I've checked the VBT and there is a BDB_LVDS_BACKLIGHT section, but
it does not set the active_low_pwm flag. This tablet re-uses the main
PCI vendor and product ids for the subsystem ids, so I see no other option
then to add a DMI based quirk to fix this.

Note that the PWM backlight code in intel_panel.c currently does not honor
the vbt.active_low_pwm flag, but that does not matter in this case.

36e191f064 drm/i915: Apply i915_request_skip() on submission
Trying to use i915_request_skip() prior to i915_request_add() causes us
to try and fill the ring upto request->postfix, which has not yet been
set, and so may cause us to memset() past the end of the ring.

Instead of skipping the request immediately, just flag the error on the
request (only accepting the first fatal error we see) and then clear the
request upon submission.

56ed441aa1 drm/i915/ehl: Check PHY type before reading DPLL frequency
intel_ddi_clock_get() tests the DPLL ID against DPLL_ID_ICL_TBTPLL (2)
to determine whether to try to descend into a TBT-specific handler.
However this test will also be true when DPLL4 on EHL is used since that
shares the same DPLL ID (2).

Add an extra check to ensure the PHY is actually a Type-C PHY before
descending into the TBT handling.  This should ensure EHL still takes
the correct code path and somewhat future-proof the code as well.

v2: Drop the gen+ check since only gen11+ platforms can have Type-C
    outputs.  (Imre)

1b79cfd99f drm: kirin: Revert "Fix for hikey620 display offset problem"
This reverts commit ff57c65138.

With the commit ff57c65138 ("drm: kirin: Fix for hikey620
display offset problem") we added support for handling LDI
overflows by resetting the hardware.

However, its been observed that when we do hit the LDI overflow
condition, the irq seems to be screaming, and we do nothing but
stream:
  [drm:ade_irq_handler [kirin_drm]] *ERROR* LDI underflow!
over and over to the screen

I've tried a few appraoches to avoid this, but none has yet
been successful and the cure here is worse then the original
disease, so revert this for now.

169c0aa4bc drm/i915/gt: Drop the timeline->mutex as we wait for retirement
As we have pinned the timeline (using tl->active_count), we can safely
drop the tl->mutex as we wait for what we believe to be the final
request on that timeline. This is useful for ensuring that we do not
block the engine heartbeat by hogging the kernel_context's timeline on a
dead GPU.

ba518bbd3f drm/i915: Force DPCD backlight mode for some Dell CML 2020 panels
According to Dell, trying to match their panels via OUI is not reliable
enough and we've been told that we should check against the EDID
instead. As well, Dell seems to have some panels that are actually
intended to switch between using PWM for backlight controls and DPCD for
backlight controls depending on whether or not the panel is in HDR or
SDR mode. Yikes.

Regardless, we need to add quirks for these so that DPCD backlight
controls get enabled by default, since without additional driver support
that's the only form of brightness control that will work. Hopefully in
the future we can remove these quirks once we have a better way of
probing for this.

Changes since v1:
* Add one more EDID per Dell's request
* Remove model number (which is possibly wrong) and replace with Dell
  CML 2020 systems

17f5d57915 drm/i915: Force DPCD backlight mode on X1 Extreme 2nd Gen 4K AMOLED panel
The X1 Extreme is one of the systems that lies about which backlight
interface that it uses in its VBIOS as PWM backlight controls don't work
at all on this machine. It's possible that this panel could be one of
the infamous ones that can switch between PWM mode and DPCD backlight
control mode, but we haven't gotten any more details on this from Lenovo
just yet. For the time being though, making sure the backlight 'just
works' is a bit more important.

So, add a quirk to force DPCD backlight controls on for these systems
based on EDID (since this panel doesn't appear to fill in the device ID).
Hopefully in the future we'll figure out a better way of probing this.

Changes since v2:
* The bugzilla URL is deprecated, bug reporting happens on gitlab now.
  Update the messages we print to reflect this
* Also, take the opportunity to move FDO_BUG_URL out of i915_utils.c and
  into i915_utils.h so that other places which print things that aren't
  traditional errors but are worth filing bugs about, can actually use
  it.

0883ce8146 drm/dp: Introduce EDID-based quirks
The whole point of using OUIs is so that we can recognize certain
devices and potentially apply quirks for them. Normally this should work
quite well, but there appears to be quite a number of laptop panels out
there that will fill the OUI but not the device ID. As such, for devices
like this I can't imagine it's a very good idea to try relying on OUIs
for applying quirks. As well, some laptop vendors have confirmed to us
that their panels have this exact issue.

So, let's introduce the ability to apply DP quirks based on EDID
identification. We reuse the same quirk bits for OUI-based quirks, so
that callers can simply check all possible quirks using
drm_dp_has_quirk().
