drm/xe/uapi: Introduce API for EU stall sampling

A new hardware feature first introduced in PVC gives capability to
periodically sample EU stall state and record counts for different stall
reasons, on a per IP basis, aggregate across all EUs in a subslice and
record the samples in a buffer in each subslice. Eventually, the aggregated
data is written out to a buffer in the memory. This feature is also
supported in XE2 and later architecture GPUs.

Use an existing IOCTL - DRM_IOCTL_XE_OBSERVATION as the interface into the
driver from the user space to do initial setup and obtain a file descriptor
for the EU stall data stream. Input parameter to the IOCTL is a struct
drm_xe_observation_param in which observation_type should be set to
DRM_XE_OBSERVATION_TYPE_EU_STALL, observation_op should be
DRM_XE_OBSERVATION_OP_STREAM_OPEN and param should point to a chain of
drm_xe_ext_set_property structures in which each structure has a pair of
property and value. The EU stall sampling input properties are defined in
drm_xe_eu_stall_property_id enum.

With the file descriptor obtained from DRM_IOCTL_XE_OBSERVATION, user space
can enable and disable EU stall sampling with the IOCTLs:
DRM_XE_OBSERVATION_IOCTL_ENABLE and DRM_XE_OBSERVATION_IOCTL_DISABLE.
User space can also call poll() to check for availability of data in the
buffer. The data can be read with read(). Finally, the file descriptor
can be closed with close().

v11: Changed a couple of variables in struct eu_stall_open_properties
from unsigned int to int.
v10: Use extension number while parsing chain of extensions.
Remove function description for static functions.
Move code around as per review feedback.
v9: Changed some u32 to unsigned int.

v7: Renamed input property DRM_XE_EU_STALL_PROP_EVENT_REPORT_COUNT
to DRM_XE_EU_STALL_PROP_WAIT_NUM_REPORTS to be consistent with
OA. Renamed the corresponding internal variables.
Fixed some commit messages based on review feedback.
v6: Change the input sampling rate to GPU cycles instead of
GPU cycles multiplier.

drm/xe/pxp: Allocate PXP execution resources

PXP requires submissions to the HW for the following operations

1) Key invalidation, done via the VCS engine
2) Communication with the GSC FW for session management, done via the
GSCCS.

Key invalidation submissions are serialized (only 1 termination can be
serviced at a given time) and done via GGTT, so we can allocate a simple
BO and a kernel queue for it.

Submissions for session management are tied to a PXP client (identified
by a unique host_session_id); from the GSC POV this is a user-accessible
construct, so all related submission must be done via PPGTT. The driver
does not currently support PPGTT submission from within the kernel, so
to add this support, the following changes have been included:

- a new type of kernel-owned VM (marked as GSC), required to ensure we
don't use fault mode on the engine and to mark the different lock
usage with lockdep.
- a new function to map a BO into a VM from within the kernel.

drm/xe: Add functions and sysfs for boot survivability

Boot Survivability is a software based workflow for recovering a system
in a failed boot state. Here system recoverability is concerned with
recovering the firmware responsible for boot.

This is implemented by loading the driver with bare minimum (no drm card)
to allow the firmware to be flashed through mei-gsc and collect telemetry.
The driver's probe flow is modified such that it enters survivability mode
when pcode initialization is incomplete and boot status denotes a failure.
In this mode, drm card is not exposed and presence of survivability_mode
entry in PCI sysfs is used to indicate survivability mode and
provide additional information required for debug

This patch adds initialization functions and exposes admin
readable sysfs entries

The new sysfs will have the below layout

/sys/bus/.../bdf

We have observed that we

drm/i915/cmtg: Disable the CMTG

The CMTG is a timing generator that runs in parallel with transcoders
timing generators and can be used as a reference for synchronization.

We have observed that we are inheriting from GOP a display configuration
with the CMTG enabled. Because our driver doesn't currently implement
any CMTG sequences, the CMTG ends up still enabled after our driver
takes over.

We need to make sure that the CMTG is not enabled if we are not going to
use it. For that, let's add a partial implementation in our driver that
only cares about disabling the CMTG if it was found enabled during
initial hardware readout. In the future, we can also implement sequences
for using the CMTG if that becomes a needed feature.

For now, we only deal with cases when it is possible to disable the CMTG
without requiring a modeset. For earlier display versions, we simply
skip if we find the CMTG enabled and we can't disable it without a
proper modeset. In the future, we need to properly handle that case.

v2:
- DG2 does not have the CMTG. Update HAS_CMTG() accordingly.
- Update logic to force disabling of CMTG only for initial commit.
v3:
- Add missing changes for v2 that were staged but not committed.
v4:
- Avoid if/else duplication in intel_cmtg_dump_state() by using "n/a"
for CMTG B enabled/disabled string for platforms without it. (Jani)
- Prefer intel_cmtg_readout_hw_state() over intel_cmtg_readout_state().
(Jani)
- Use display struct instead of i915 as first parameter for
TRANS_DDI_FUNC_CTL2(). (Jani)
- Fewer continuation lines in variable declaration/initialization for
better readability. (Jani)
- Coding style improvements. (Jani)
- Use drm_dbg_kms() instead of drm_info() for logging the disabling
of the CMTG.
- Make struct intel_cmtg_state entirely private to intel_cmtg.c.
v5:
- Do the disable sequence as part of the sanitization step after
hardware readout instead of initial modeset commit. (Jani)
- Adapt to commit 15133582465f ("drm/i915/display: convert global state
to struct intel_display") by using a display struct instead of i915
as argument for intel_atomic_global_obj_init().
v6:
- Do not track CMTG state as a global state. (Ville)
- Simplify the driver logic by only disabling the CMTG only on cases
when a modeset is not required. (Ville)
v7:
- Remove the call to drm_WARN_ON() when checking
intel_cmtg_disable_requires_modeset() and use a FIXME in the comment
instead.
- Remove the !HAS_CMTG() guard from intel_cmtg_get_config(), which is
static and its caller is already protected by that same condition.
- Also take the opportunity to put some Bspec references in the commit
trailers section.
v8:
- Use HAS_TRANSCODER() instead of intel_crtc_for_pipe(). (Ville)
- Ensure transcoder power well is enabled before reading
TRANS_DDI_FUNC_CTL2. (Ville)

drm/xe/vf: React to MIGRATED interrupt

To properly support VF Save/Restore procedure, fixups need to be
applied after PF driver finishes its part of VF Restore. The fixups
are required to adjust the ongoing execution for a hardware switch
that happened, because some GFX resources are not fully virtualized,
and assigned to a VF as range from a global pool. The VF on which
a VM is restored will often have different ranges provisioned than
the VF on which save process happened. Those resource fixups are
applied by the VF driver within a restored VM.

A VF driver gets informed that it was migrated by receiving an
interrupt from each GuC. The interrupt assigned for that purpose
is "GUC SW interrupt 0". Seeing that fields set from within the
irq handler should be the trigger for fixups.

The VF can safely do post-migration fixups on resources associated
to each GuC only after that GuC issued the MIGRATED interrupt.

This change introduces a worker to be used for post-migration fixups,
and a mechanism to schedule said worker when all GuCs sent the irq.

drm/i915/display: start a buffer object abstraction layer

The display code needs to deal with gem objects, and mostly uses struct
drm_i915_gem_object. That's not great, because for xe we need to
redefine it struct xe_bo during build.

Start a common interface using struct drm_gem_object, with separate
implementations for i915 and xe. For starters, convert i9xx_wm.c to use
it.

drm/xe/pf: Add functions to save and restore VF GuC state

To successfully migrate a VM with attached GPU VF we also need to
migrate VF's GuC state. Add necessary functions that interacts with
GuC to save and restore a VF GuC state. We will start using them in
upcoming patches.

Since VF migration requires many more changes in the driver, enable
those functions only under debug config.
