drm/vkms: Update testing with IGT IGT_DEVICE 
VKMS is no longer in the platform bus, instead, it is in the faux bus.

In addition, when present, IGT picks hardware drivers instead of virtual
drivers, like VKMS or vgem, if they are not forced.

Update the documentation to use IGT_FORCE_DRIVER instead of IGT_DEVICE.

Louis Chauvet 13fc9b9745 drm/vkms: Add and remove VKMS instances via configfs 
Allow to create, enable, disable and destroy VKMS instances using
configfs.

For the moment, it is not possible to add pipeline items, so trying to
enable the device will fail printing an informative error to the log.

Thomas Zimmermann 74afeb8128 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 3a0709928b ("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

Thomas Zimmermann fb24aaf541 drm/dumb-buffers: Provide helper to set pitch and size 
Add drm_modes_size_dumb(), a helper to calculate the dumb-buffer
scanline pitch and allocation size. Implementations of struct
drm_driver.dumb_create can call the new helper for their size
computations.

There is currently quite a bit of code duplication among DRM's
memory managers. Each calculates scanline pitch and buffer size
from the given arguments, but the implementations are inconsistent
in how they treat alignment and format support. Later patches will
unify this code on top of drm_mode_size_dumb() as much as possible.

drm_mode_size_dumb() uses existing 4CC format helpers to interpret
the given color mode. This makes the dumb-buffer interface behave
similar the kernel's video= parameter. Current per-driver implementations
again likely have subtle differences or bugs in how they support color
modes.

The dumb-buffer UAPI is only specified for known color modes. These
values describe linear, single-plane RGB color formats or legacy index
formats. Other values should not be specified. But some user space
still does. So for unknown color modes, there are a number of known
exceptions for which drm_mode_size_dumb() calculates the pitch from
the bpp value, as before. All other values work the same but print
an error.

v6:
- document additional use cases for DUMB_CREATE2 in TODO list (Tomi)
- fix typos in documentation (Tomi)
v5:
- check for overflows with check_mul_overflow() (Tomi)
v4:
- use %u conversion specifier (Geert)
- list DRM_FORMAT_Dn in UAPI docs (Geert)
- avoid dmesg spamming with drm_warn_once() (Sima)
- add more information about bpp special case (Sima)
- clarify parameters for hardware alignment
- add a TODO item for DUMB_CREATE2
v3:
- document the UAPI semantics
- compute scanline pitch from for unknown color modes (Andy, Tomi)

Alexandre Courbot a841614e60 gpu: nova-core: firmware: process and prepare the GSP firmware 
The GSP firmware is a binary blob that is verified, loaded, and run by
the GSP bootloader. Its presentation is a bit peculiar as the GSP
bootloader expects to be given a DMA address to a 3-levels page table
mapping the GSP firmware at address 0 of its own address space.

Prepare such a structure containing the DMA-mapped firmware as well as
the DMA-mapped page tables, and a way to obtain the DMA handle of the
level 0 page table.

Then, move the GSP firmware instance from the `Firmware` struct to the
`start_gsp` method since it doesn't need to be kept after the GSP is
booted.

As we are performing the required ELF section parsing and radix3 page
table building, remove these items from the TODO file.

drm: Add a vendor-specific recovery method to drm device wedged uevent 
Address the need for a recovery method (firmware flash on Firmware errors)
introduced in the later patches of Xe KMD.
Whenever XE KMD detects a firmware error, a firmware flash is required to
recover the device to normal operation.

The initial proposal to use 'firmware-flash' as a recovery method was
not applicable to other drivers and could cause multiple recovery
methods specific to vendors to be added.
To address this a more generic 'vendor-specific' method is introduced,
guiding users to refer to vendor specific documentation and system logs
for detailed vendor specific recovery procedure.

Add a recovery method 'WEDGED=vendor-specific' for such errors.
Vendors must provide additional recovery documentation if this method
is used.

It is the responsibility of the consumer to refer to the correct vendor
specific documentation and usecase before attempting a recovery.

For example: If driver is XE KMD, the consumer must refer
to the documentation of 'Device Wedging' under 'Documentation/gpu/xe/'.

v2: fix documentation (Raag)
v3: add more details to commit message (Sima, Rodrigo, Raag)
    add an example script to the documentation (Raag)
v4: use consistent naming (Raag)
v5: fix commit message

Alexandre Courbot 0988099646 gpu: nova-core: register: add support for relative array registers 
Add support for declaring arrays of registers available from a variable
base. This is effectively a combination of the relative and array
registers features.

nova-core does not make much use of this yet, but it will become helpful
to have for GSP boot.

Alexandre Courbot af10924fc4 gpu: nova-core: register: redesign relative registers 
The relative registers are currently very unsafe to use: callers can
specify any constant as the base address for access, meaning they can
effectively interpret any I/O address as any relative register.

Ideally, valid base addresses for a family of registers should be
explicitly defined in the code, and could only be used with the relevant
registers

This patch changes the relative register declaration from e.g.:

    register!(CPU_CTL @ +0x0000010, "CPU core control" {
        0:0     start as bool, "Start the CPU core";
    });

into:

    register!(CPU_CTL @ CpuCtlBase[0x10], "CPU core control" {
        0:0     start as bool, "Start the CPU core";
    });

Where `CpuCtlBase` is the name of a ZST used as a parameter of the
`RegisterBase<>` trait to define a trait unique to a class of register.
This specialized trait is then implemented for every type that provides
a valid base address, enabling said types to be passed as the base
address provider for the register's I/O accessor methods.

This design thus makes it impossible to pass an unexpected base address
to a relative register, and, since the valid bases are all known at
compile-time, also guarantees that all I/O accesses are done within the
valid bounds of the I/O range.

[acourbot@nvidia.com: add example in the commit log.]
