drm/ras: Introduce the DRM RAS infrastructure over generic netlink

Introduces the DRM RAS infrastructure over generic netlink.

The new interface allows drivers to expose RAS nodes and their
associated error counters to userspace in a structured and extensible
way. Each drm_ras node can register its own set of error counters, which
are then discoverable and queryable through netlink operations. This
lays the groundwork for reporting and managing hardware error states
in a unified manner across different DRM drivers.

Currently it only supports error-counter nodes. But it can be
extended later.

The registration is also not tied to any drm node, so it can be
used by accel devices as well.

It uses the new and mandatory YAML description format stored in
Documentation/netlink/specs/. This forces a single generic netlink
family namespace for the entire drm: "drm-ras".
But multiple-endpoints are supported within the single family.

Any modification to this API needs to be applied to
Documentation/netlink/specs/drm_ras.yaml before regenerating the
code:

Documentation/netlink/specs/drm_ras.yaml --mode uapi --header \

drm: verisilicon: add a driver for Verisilicon display controllers

This is a from-scratch driver targeting Verisilicon DC-series display
controllers, which feature self-identification functionality like their
GC-series GPUs.

Only DC8200 is being supported now, and only the main framebuffer is set
up (as the DRM primary plane). Support for more DC models and more
features is my further targets.

As the display controller is delivered to SoC vendors as a whole part,
this driver does not use component framework and extra bridges inside a
SoC is expected to be implemented as dedicated bridges (this driver
properly supports bridge chaining).

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.

drm/pagemap: Add a drm_pagemap cache and shrinker

Pagemaps are costly to set up and tear down, and they consume a lot
of system memory for the struct pages. Ideally they should be
created only when needed.

Add a caching mechanism to allow doing just that: Create the drm_pagemaps
when needed for migration. Keep them around to avoid destruction and
re-creation latencies and destroy inactive/unused drm_pagemaps on memory
pressure using a shrinker.

Only add the helper functions. They will be hooked up to the xe driver
in the upcoming patch.

- Add lockdep checking for drm_pagemap_put(). (Matt Brost)

drm/client: Support emergency restore via sysrq for all clients

Move the sysrq functionality from DRM fbdev helpers to the DRM device
and in-kernel clients, so that it becomes available on all clients.

DRM fbdev helpers support emergency restoration of the console output
via a special key combination. Press SysRq+v to replace the current
compositor with the kernel's output on the framebuffer console. This
allows users to see the log messages during system emergencies.

By moving the functionality from fbdev helpers to the DRM device, any
in-kernel client can serve as emergency output. This can be used to
bring up drm_log, for example.

Each DRM device registers itself to the list of possible sysrq handlers.
On receiving SysRq+v, the DRM core goes over all registered devices and
restores an in-kernel DRM client for each of them.

See Documentation/admin-guide/sysrq.rst on how to invoke SysRq. Switch
VTs to bring back the user-space compositor.

v2:
- declare placeholders as 'static inline' (kernel test robot)
- fix grammar in commit description

kbuild: Let kernel-doc.py use PYTHON3 override

It is possible to force a specific version of python to be used when
building the kernel by passing PYTHON3= on the make command line.
However kernel-doc.py is currently called with python3 hard-coded and
thus ignores this setting.

Use $(PYTHON3) to run $(KERNELDOC) so that the desired version of
python is used.

drm/vblank: Add vblank timer

The vblank timer simulates a vblank interrupt for hardware without
support. Rate-limits the display update frequency.

DRM drivers for hardware without vblank support apply display updates
ASAP. A vblank event informs DRM clients of the completed update.
Userspace compositors immediately schedule the next update, which
creates significant load on virtualization outputs. Display updates
are usually fast on virtualization outputs, as their framebuffers are
in regular system memory and there's no hardware vblank interrupt to
throttle the update rate.

The vblank timer is a HR timer that signals the vblank in software.
It limits the update frequency of a DRM driver similar to a hardware
vblank interrupt. The timer is not synchronized to the actual vblank
interval of the display.

The code has been adopted from vkms, which added the funtionality
in commit 3a0709928b17 ("drm/vkms: Add vblank events simulated by
hrtimers").

The new implementation is part of the existing vblank support,
which sets up the timer automatically. Drivers only have to start
and cancel the vblank timer as part of enabling and disabling the
CRTC. The new vblank helper library provides callbacks for struct
drm_crtc_funcs.

The standard way for handling vblank is to call drm_crtc_handle_vblank().
Drivers that require additional processing, such as vkms, can init
handle_vblank_timeout in struct drm_crtc_helper_funcs to refer to
their timeout handler.

There's a possible deadlock between drm_crtc_handle_vblank() and
hrtimer_cancel(). [1] The implementation avoids to call hrtimer_cancel()
directly and instead signals to the timer function to not restart
itself.

v4:
- fix possible race condition between timeout and atomic commit (Michael)
v3:
- avoid deadlock when cancelling timer (Ville, Lyude)
v2:
- implement vblank timer entirely in vblank helpers
- downgrade overrun warning to debug
- fix docs
