2bbd6dba84 drm/i915: Try to use fast+narrow link on eDP again and fall back to the old max strategy on failure
Some new eDP panels don't like to operate at the max parameters, and
instead we need to go for an optimal confiugration. That unfortunately
doesn't work with older eDP panels which are generally only guaranteed
to work at the max parameters.

To solve these two conflicting requirements let's start with the optimal
setup, and if that fails we start again with the max parameters. The
downside is probably an extra modeset when we switch strategies but
I don't see a good way to avoid that.

For a bit of history we first tried to go for the fast+narrow in
commit 7769db5883 ("drm/i915/dp: optimize eDP 1.4+ link config
fast and narrow"). but that had to be reverted due to regression
on older panels in commit f11cb1c19a ("drm/i915/dp: revert back
to max link rate and lane count on eDP"). So now we try to get
the best of both worlds by using both strategies.

ff7fb44d00 drm/i915: Fix HTI port checking
There was some misinterpretation of specification, when DDIX_USED is
set, the next bit means 0 for DP and 1 for HDMI.

Anyways this misinterpretation is not causing any issues, this change
is just to comply with specification.
Also as for us it do not matters if it is HDMI or DP, not checking the
port type that HTI is using.

0d4ced1c5b drm/i915/backlight: fix CPU mode backlight takeover on LPT
The pch_get_backlight(), lpt_get_backlight(), and lpt_set_backlight()
functions operate directly on the hardware registers. If inverting the
value is needed, using intel_panel_compute_brightness(), it should only
be done in the interface between hardware registers and
panel->backlight.level.

The CPU mode takeover code added in commit 5b1ec9ac7a
("drm/i915/backlight: Fix backlight takeover on LPT, v3.") reads the
hardware register and converts to panel->backlight.level correctly,
however the value written back should remain in the hardware register
"domain".

This hasn't been an issue, because GM45 machines are the only known
users of i915.invert_brightness and the brightness invert quirk, and
without one of them no conversion is made. It's likely nobody's ever hit
the problem.

751f82b353 drm/i915/gt: Only disable preemption on gen8 render engines
The reason why we did not enable preemption on Broadwater was due to
missing GPGPU workarounds. Since this only applies to rcs0, only
restrict rcs0 (and our global capabilities).

While this does not affect exposing a preemption capability to
userspace, it does affect our internal decisions on whether to use
timeslicing and semaphores between individual engines.

b1ad5f6d68 drm/i915/gt: Only retire on the last breadcrumb if the last request
We use the completion of the last active breadcrumb to retire the
requests along a timeline. This is purely opportunistic as nothing
guarantees that any particular timeline is terminated by a breadcrumb;
except for parking the engine where we explicitly add a breadcrumb so
that we park quickly and do an explicit retire upon signaling to reduce
the latency dramatically (avoiding a retire worker roundtrip).

With scheduling, we anticipate retiring completed timelines as a matter
of course. Performing the same action from inside the breadcrumbs is
intended to provide similar functionality for legacy ringbuffer
submission.

previous breadcrumbs. On switch to a new physical engine, that link will

This patch undoes a last minute mistake introduced into commit
bab0557c8d ("drm/i915/gt: Remove virtual breadcrumb before transfer"),
whereby instead of unconditionally applying the flush, it was only
applied if the request itself was going to be reused.

08da4fcd6d drm/amd/pm: modify the fine grain tuning function for Renoir
This patch is to improve the fine grain tuning function for Renoir.
The fine grain tuning function uses the sysfs node -- pp_od_clk_voltage
to config gfxclk. Meanwhile, another sysfs
node -- power_dpm_force_perfomance_level also affects the gfx clk.
It will cause confusion when these two sysfs nodes works
together.
And the flag "od_enabled" is used to control the overdrive function for
dGPU, like navi10, navi14 and navi21.
APU like Renior or Vangogh uses this "od_enabled" to configure
the frequency range of gfx clock, but the max value of frequency
range will not be higher than the safe limit, it is not "overdrive".
So this patch adds two new flags -- "fine_grain_enabled" and
"fine_grain_started" to avoid this confusion, the flag will
make these two sysfs nodes work separately.
The flag "fine_grain_enabled" is set as "enabled" by default,
so the fine grain tuning function will be enabled by default.
But the flag "fine_grain_started" is set as "false" by default,
so the fine grain function will not take effect until it is set as
"true".
Only when power_dpm_force_perfomance_level is changed to
"manual" mode, the flag "fine_grain_started" will be set as "true",
and the fine grain tuning function will be started.
In other profile modes, including "auto", "high", "low", "profile_peak",
"profile_standard", "profile_min_sclk", "profile_min_mclk",
the flag "fine_grain_started" will be set as "false", and the od range of
fine grain tuning function will be restored default value.

4386b8e5ad drm/i915/gt: Remove timeslice suppression
In the next^W future patch, we remove the strict priority system and
continuously re-evaluate the relative priority of tasks. As such we need
to enable the timeslice whenever there is more than one context in the
pipeline. This simplifies the decision and removes some of the tweaks to
suppress timeslicing, allowing us to lift the timeslice enabling to a
common spot at the end of running the submission tasklet.

One consequence of the suppression is that it was reducing fairness
between virtual engines on an over saturated system; undermining the
principle for timeslicing.

6fdb335f1c drm/i915/dsi: Use unconditional msleep for the panel_on_delay when there is no reset-deassert MIPI-sequence
Commit 25b4620ee8 ("drm/i915/dsi: Skip delays for v3 VBTs in vid-mode")
added an intel_dsi_msleep() helper which skips sleeping if the
MIPI-sequences have a version of 3 or newer and the panel is in vid-mode;
and it moved a bunch of msleep-s over to this new helper.

This was based on my reading of the big comment around line 730 which
starts with "Panel enable/disable sequences from the VBT spec.",
where the "v3 video mode seq" column does not have any wait t# entries.

Given that this code has been used on a lot of different devices without
issues until now, it seems that my interpretation of the spec here is
mostly correct.

But now I have encountered one device, an Acer Aspire Switch 10 E
SW3-016, where the panel will not light up unless we do actually honor the
panel_on_delay after exexuting the MIPI_SEQ_PANEL_ON sequence.

What seems to set this model apart is that it is lacking a
MIPI_SEQ_DEASSERT_RESET sequence, which is where the power-on
delay usually happens.

Fix the panel not lighting up on this model by using an unconditional
msleep(panel_on_delay) instead of intel_dsi_msleep() when there is
no MIPI_SEQ_DEASSERT_RESET sequence.

Add support for DP-HDMI2.1 PCON

From the series cover letter:

This patch series attempts to add support for a DP-HDMI2.1 Protocol
Convertor. The VESA spec for the HDMI2.1 PCON are proposed in Errata
E5 to DisplayPort_v2.0:
https://vesa.org/join-vesamemberships/member-downloads/?action=stamp&fileid=42299
The details are mentioned in:
VESA DP-to-HDMI PCON Specification Standalone Document
https://groups.vesa.org/wg/DP/document/15651

This series starts with adding support for FRL (Fixed Rate Link)
Training between the PCON and HDMI2.1 sink.
As per HDMI2.1 specification, a new data-channel or lane is added in
FRL mode, by repurposing the TMDS clock Channel. Through FRL, higher
bit-rate can be supported, ie. up to 12 Gbps/lane (48 Gbps over 4
lanes).

With these patches, the HDMI2.1 PCON can be configured to achieve FRL
training based on the maximum FRL rate supported by the panel, source
and the PCON.
The approach is to add the support for FRL training between PCON and
HDMI2.1 sink and gradually add other blocks for supporting higher
resolutions and other HDMI2.1 features, that can be supported by pcon
for the sources that do not natively support HDMI2.1.

This is done before the DP Link training between the source and PCON
is started. In case of FRL training is not achieved, the PCON will
work in the regular TMDS mode, without HDMI2.1 feature support.
Any interruption in FRL training between the PCON and HDMI2.1 sink is
notified through IRQ_HPD. On receiving the IRQ_HPD the concerned DPCD
registers are read and FRL training is re-attempted.

Currently, we have tested the FRL training and are able to enable 4K
display with TGL Platform + Realtek PCON RTD2173 with HDMI2.1 supporting
panel.

Refer to commit cd0a89527d ("drm/i915/rkl: Add DDC pin mapping").
Create two ddc pin table for rkl TGP and CMP pch. Then HDMI can
works properly on rkl.

v2: update patch based on latest dinq branch.
v3: update ddc table for RKL+TGP sku.
    RKL+CNP sku will load cnp_ddc_pin_map[] setting.
v4: modify the if/else judgment to avoid nesting.
v5: fix typo in v4.

e4180c4253 drm/amdgpu: Add check to prevent IH overflow
Similar to commit <b82175750131>("drm/amdgpu: fix IH overflow on Vega10 v2").
When an ring buffer overflow happens the appropriate bit is set in the WPTR
register which is also written back to memory. But clearing the bit in the
WPTR doesn't trigger another memory writeback.

So what can happen is that we end up processing the buffer overflow over and
over again because the bit is never cleared. Resulting in a random system
lockup because of an infinite loop in an interrupt handler.

88d5cb2517 drm/amdgpu/display: drop DCN support for aarch64
From Ard:

"Simply disabling -mgeneral-regs-only left and right is risky, given that
the standard AArch64 ABI permits the use of FP/SIMD registers anywhere,
and GCC is known to use SIMD registers for spilling, and may invent
other uses of the FP/SIMD register file that have nothing to do with the
floating point code in question. Note that putting kernel_neon_begin()
and kernel_neon_end() around the code that does use FP is not sufficient
here, the problem is in all the other code that may be emitted with
references to SIMD registers in it.

So the only way to do this properly is to put all floating point code in
a separate compilation unit, and only compile that unit with
-mgeneral-regs-only."

Disable support until the code can be properly refactored to support this
properly on aarch64.

4b6b7437b1 drm/amd/display: Enable fp16 also on DCE-8/10/11.
The hw supports fp16, this is not only useful for HDR,
but also for standard dynamic range displays, because
it allows to get more precise color reproduction with
about 11 - 12 bpc linear precision in the unorm range
0.0 - 1.0.

Working fp16 scanout+display (and HDR over HDMI) was
verified on a DCE-8 asic, so i assume that the more
recent DCE-10/11 will work equally well, now that
format-specific plane scaling constraints are properly
enforced, e.g., the inability of fp16 to scale on older
hw like DCE-8 to DCE-11.

2d00164350 drm/amd/pm: improve the fine grain tuning function for RV/RV2/PCO
This patch is to improve the fine grain tuning function for RV/RV2/PCO.
The fine grain tuning function uses the sysfs node -- pp_od_clk_voltage
to config gfxclk. Meanwhile, another sysfs
node -- power_dpm_force_perfomance_level also affects the gfx clk.
It will cause confusion when these two sysfs nodes works
together. So this patch adds one flag to avoid this confusion, the flag
will make these two sysfs nodes work separately.
The flag is set as "disabled" by default, so the fine grain tuning function
will be disabled by default.
Only when power_dpm_force_perfomance_level is changed to
"manual" mode, the flag will be set as "enabled",
and the fine grain tuning function will be enabled.
In other profile modes, including "auto", "high", "low",
"profile_peak", "profile_standard", "profile_min_sclk",
"profile_min_mclk", the flag will be set as "disabled",
and the od range of fine grain tuning function will
be restored default value.

ea173d15b2 drm/amd/pm: add support to umd P-state function for vangogh
This patch is to add support to umd P-state function for vangogh.
It enables the "set" function of 3 sysfs nodes: pp_dpm_mclk,
pp_dpm_fclk, pp_dpm_socclk, the functions is used to set the DPM
frequency level of memclk/fclk/socclk.
Due to only after enabling the "power_dpm_force_performance_level"
sysfs node, it is allowed to set these three nodes,
so this patch also enables the "powe_dpm_force_performance_level"
sysfs node, which is used to change power profile.

ca55f459f5 drm/amd/pm: add the fine grain tuning function for renoir
This patch is to add the fine grain tuning function for renoir.
This function uses the pp_od_clk_voltage sysfs file to configure the min
and max value of gfx clock frequency manually or restore the default value.

Command guide:
echo "s level value" > pp_od_clk_voltage
        "s" - set the sclk frequency
        "level" - 0 or 1, "0" represents the min value,  "1" represents
        the max value
        "value" - the target value of sclk frequency, it should
        be limited in the safe range
echo "r" > pp_od_clk_voltage
        "r" - reset the sclk frequency, restore the default value instantly
echo "c" > pp_od_clk_voltage
        "c" - commit the min and max value of sclk frequency to the system
        only after the commit command, the target values set by "s" command
        will take effect.
Example:
1)change power profile from "auto" to "standard"
        $ cat power_dpm_force_performance_level
        auto
        $ echo "profile_standard" > power_dpm_force_performance_level
        $ cat power_dpm_force_performance_level
        profile_standard
2)check the default sclk frequency
        $ cat pp_od_clk_voltage
        OD_SCLK:
        0:        200Mhz
        1:       1400Mhz
        OD_RANGE:
        SCLK:     200MHz       1400MHz
3)use "s" -- set command to configure the min and max sclk frequency
        $ echo "s 0 600" > pp_od_clk_voltage
        $ echo "s 1 1000" > pp_od_clk_voltage
        $ echo "c" > pp_od_clk_voltage
        $ cat pp_od_clk_voltage
        OD_SCLK:

9577b0ec2b drm/amd/pm: add two new sysfs nodes for vangogh
This patch is to add two new sysfs nodes for vangogh:
pp_dpm_dclk and pp_dpm_vclk.
The two sysfs nodes are similar to pp_dpm_fclk/memclk/socclk.
pp_dpm_dclk represents the DPM frequency of dcn unit.
pp_dpm_vclk represents the DPM frequency of vcn unit.

This patch is to add new feature map macros to resolve duplicate name.
Vangogh uses one different format to name some feature bits of swSMU, it
causes some duplicate name in the existing feature map list.

ae7b32e7c3 drm/amd/pm: add support to umd P-state "fetch" function for vangogh
This patch is to add supoort to umd P-state function for vangogh.
It enables the "fetch" function of 3 sysfs nodes: pp_dpm_mclk,
pp_dpm_fclk, pp_dpm_socclk,the function is used to fetch
the current frequency of memclk/fclk/socclk.

3fea9f4244 drm/i915/display/psr: Use plane damage clips to calculate damaged area
Now using plane damage clips property to calcualte the damaged area.
Selective fetch only supports one region to be fetched so software
needs to calculate a bounding box around all damage clips.

Now that we are not complete fetching each plane, there is another
loop needed as all the plane areas that intersect with the pipe
damaged area needs to be fetched from memory so the complete blending
of all planes can happen.

v2:
- do not shifting new_plane_state->uapi.dst only src is in 16.16 format

v4:
- setting plane selective fetch area using the whole pipe damage area
- mark the whole plane area damaged if plane visibility or alpha
changed

v5:
- taking in consideration src.y1 in the damage coordinates
- adding to the pipe damaged area planes that were visible but are
invisible in the new state

v6:
- consider old state plane coordinates when visibility changes or it
moved to calculate damaged area
- remove from damaged area the portion not in src clip

v7:
- intersec every damage clip with src to minimize damaged area

v8:
- adjust pipe_damaged area to 4 lines grouping
- adjust calculation now that is understood that uapi.src is the
framebuffer coordinates that plane will start to fetch from

v9:
- Only add plane dst or src to damaged_area if visible
- Early skip plane damage calculation if it was not visible in old and
new state

8d03344b9d drm/i915/selftests: Switch 4k kmalloc to use get_free_page for alignment
In generating the reference LRC, we want a page-aligned address for
simplicity in computing the offsets within. This then shares the
computation for the HW LRC which is mapped and so page aligned, making
the comparison straightforward. It seems that kmalloc(4k) is not always
returning from a 4k-aligned slab cache (which would give us a page aligned
address) so force alignment by explicitly allocating a page.
