f377ea0561 Revert "drm/amd/display: pause the workload setting in dm"
This reverts commit bc6d54ac7e.

The workload profile needs to be in the default state when
the dc idle optimizaion state is entered.  However, when
jobs come in for video or GFX or compute, the profile may
be set to a non-default profile resulting in the dc idle
optimizations not taking affect and resulting in higher
power usage.  As such we need to pause the workload profile
changes during this transition.  When this patch was originally
committed, it caused a regression with a Dell U3224KB display,
but no other problems were reported at the time.  When it
was reapplied (this patch) to address increased power usage, it
seems to have caused additional regressions.  This change seems
to have a number of side affects (audio issues, stuttering,
etc.).  I suspect the pause should only happen when all displays
are off or in static screen mode, but I think this call site
gets called more often than that which results in idle state
entry more often than intended.  For now revert.

e27ada4f19 drm/xe: Select CONFIG_DEVICE_PRIVATE when DRM_XE_GPUSVM is selected
CONFIG_DEVICE_PRIVATE is a prerequisite for DRM_XE_GPUSVM.
Explicitly select it so that DRM_XE_GPUSVM is not unintentionally
left out from distro configs not explicitly enabling
CONFIG_DEVICE_PRIVATE.

v2:
- Select also CONFIG_ZONE_DEVICE since it's needed by
  CONFIG_DEVICE_PRIVATE.
v3:
- Depend on CONFIG_ZONE_DEVICE rather than selecting it.

bdcdf968be drm, drm/xe: Fix xe userptr in the absence of CONFIG_DEVICE_PRIVATE
CONFIG_DEVICE_PRIVATE is not selected by default by some distros,
for example Fedora, and that leads to a regression in the xe driver
since userptr support gets compiled out.

It turns out that DRM_GPUSVM, which is needed for xe userptr support
compiles also without CONFIG_DEVICE_PRIVATE, but doesn't compile
without CONFIG_ZONE_DEVICE.
Exclude the drm_pagemap files from compilation with !CONFIG_ZONE_DEVICE,
and remove the CONFIG_DEVICE_PRIVATE dependency from CONFIG_DRM_GPUSVM and
the xe driver's selection of it, re-enabling xe userptr for those configs.

v2:
- Don't compile the drm_pagemap files unless CONFIG_ZONE_DEVICE is set.
- Adjust the drm_pagemap.h header accordingly.

d0bd10792d drm/nouveau: implement missing DCB connector types; gracefully handle unknown connectors
* Implement missing DCB connectors in uconn.c previously defined in conn.h.
* Replace kernel WARN_ON macro with printk message to more gracefully signify
  an unknown connector was encountered.

With this patch, unknown connectors are explicitly marked with value 0
(DCB_CONNECTOR_VGA) to match the tested current behavior. Although 0xff
(DCB_CONNECTOR_NONE) may be more suitable, I don't want to introduce a
breaking change.

3036b4ce4b drm/nouveau: add missing DCB connector types
* Add missing DCB connectors in conn.h as per the NVIDIA DCB specification.

A lot of connector logic was rewritten for Linux v6.5; some display connector types
went unaccounted-for which caused kernel warnings on devices with the now-unsupported
DCB connectors. This patch adds all of the DCB connectors as defined by NVIDIA to the
dcb_connector_type enum to bring back support for these connectors to the new logic.

764a90eb02 drm/amd/pm: Workaround SI powertune issue on Radeon 430 (v2)
Radeon 430 and 520 are OEM GPUs from 2016~2017
They have the same device id: 0x6611 and revision: 0x87

On the Radeon 430, powertune is buggy and throttles the GPU,
never allowing it to reach its maximum SCLK. Work around this
bug by raising the TDP limits we program to the SMC from
24W (specified by the VBIOS on Radeon 430) to 32W.

Disabling powertune entirely is	not a viable workaround,
because	it causes the Radeon 520 to heat up above 100 C,
which I prefer to avoid.

Additionally, revise the maximum SCLK limit. Considering the
above issue, these GPUs never reached a high SCLK on Linux,
and the workarounds were added before the GPUs were released,
so the workaround likely didn't target these specifically.
Use 780 MHz (the maximum SCLK according to the VBIOS on the
Radeon 430). Note that the Radeon 520 VBIOS has a higher
maximum SCLK: 905 MHz, but in practice it doesn't seem to
perform better with the higher clock, only heats up more.

v2:
Move the workaround to si_populate_smc_tdp_limits.

532e2c87d4 drm/amdkfd: Do not include VGPR MSBs in saved PC during save
The current trap handler uses the top bits of ttmp1 to store a copy of
sq_wave_mode.*vgpr_msb (except for src2_vgpr_msb).  This is so the
effective values in sq_wave_mode can be cleared to ensure correct
behavior of the trap handler.

When saving sq_wave_mode, the trap handler correctly rebuilds the
expected value (with *vgpr_msb restored), so the save area is correct.
However, the PC itself is copied from ttmp[0:1], which contains the
wave's PC as well as the saved MSBs.

The debugger reads the PC from the save area and is confused when non-0
values from VGPR_MSBs are present.

This patch fixes this by saving the PC in the save area's PC slot, not
the composite of the PC and VGPR_MSBs.  On restore, the VGPR_MSBs are
restored from sq_wave_mode.

966d70f1e1 drm/amd/pm: Workaround SI powertune issue on Radeon 430 (v2)
Radeon 430 and 520 are OEM GPUs from 2016~2017
They have the same device id: 0x6611 and revision: 0x87

On the Radeon 430, powertune is buggy and throttles the GPU,
never allowing it to reach its maximum SCLK. Work around this
bug by raising the TDP limits we program to the SMC from
24W (specified by the VBIOS on Radeon 430) to 32W.

Disabling powertune entirely is	not a viable workaround,
because	it causes the Radeon 520 to heat up above 100 C,
which I prefer to avoid.

Additionally, revise the maximum SCLK limit. Considering the
above issue, these GPUs never reached a high SCLK on Linux,
and the workarounds were added before the GPUs were released,
so the workaround likely didn't target these specifically.
Use 780 MHz (the maximum SCLK according to the VBIOS on the
Radeon 430). Note that the Radeon 520 VBIOS has a higher
maximum SCLK: 905 MHz, but in practice it doesn't seem to
perform better with the higher clock, only heats up more.

v2:
Move the workaround to si_populate_smc_tdp_limits.

f262015b97 drm/xe: Update wedged.mode only after successful reset policy change
Previously, the driver's internal wedged.mode state was updated without
verifying whether the corresponding engine reset policy update in GuC
succeeded. This could leave the driver reporting a wedged.mode state
that doesn't match the actual reset behavior programmed in GuC.

With this change, the reset policy is updated first, and the driver's
wedged.mode state is modified only if the policy update succeeds on all
available GTs.

This patch also introduces two functional improvements:

 - The policy is sent to GuC only when a change is required. An update
   is needed only when entering or leaving XE_WEDGED_MODE_UPON_ANY_HANG,
   because only in that case the reset policy changes. For example,
   switching between XE_WEDGED_MODE_UPON_CRITICAL_ERROR and
   XE_WEDGED_MODE_NEVER doesn't affect the reset policy, so there is no
   need to send the same value to GuC.

 - An inconsistent_reset flag is added to track cases where reset policy
   update succeeds only on a subset of GTs. If such inconsistency is
   detected, future wedged mode configuration will force a retry of the
   reset policy update to restore a consistent state across all GTs.

6f4b7aed61 drm/xe/uapi: disallow bind queue sharing
Currently this is very broken if someone attempts to create a bind
queue and share it across multiple VMs. For example currently we assume
it is safe to acquire the user VM lock to protect some of the bind queue
state, but if allow sharing the bind queue with multiple VMs then this
quickly breaks down.

To fix this reject using a bind queue with any VM that is not the same
VM that was originally passed when creating the bind queue. This a uAPI
change, however this was more of an oversight on kernel side that we
didn't reject this, and expectation is that userspace shouldn't be using
bind queues in this way, so in theory this change should go unnoticed.

Based on a patch from Matt Brost.

v2 (Matt B):
  - Hold the vm lock over queue create, to ensure it can't be closed as
    we attach the user_vm to the queue.
  - Make sure we actually check for NULL user_vm in destruction path.
v3:
  - Fix error path handling.
