Add an early_init phase to MES for fetching and validating microcode
from the filesystem.
If MES microcode is required but not available during early init, the
firmware framebuffer will have already been released and the screen will
freeze.
Move the request for MES microcode into the early_init phase
so that if it's not available, early_init will fail.

Currently, there are issues with enabling PSR-SU + DSC. This stems from
the fact that DSC imposes a slice height on transmitted video data and
we are not conforming to that slice height in PSR-SU regions. So, pass
slice_height into su_y_granularity to feed the DSC slice height into
PSR-SU code.

All microcode runs a basic validation after it's been loaded. Each
IP block as part of init will run both.
Introduce a wrapper for request_firmware and amdgpu_ucode_validate.
This wrapper will also remap any error codes from request_firmware
to -ENODEV. This is so that early_init will fail if firmware couldn't
be loaded instead of the IP block being disabled.

Removing the firmware framebuffer from the driver means that even
if the driver doesn't support the IP blocks in a GPU it will no
longer be functional after the driver fails to initialize.
This change will ensure that unsupported IP blocks at least cause
the driver to work with the EFI framebuffer.

Add support for the 1080x2400 Visionox VTDR6130 AMOLED DSI panel
found on the Qualcomm SM8550 MTP board.
By default the the panel is configured to work with DSI compressed
streams, but can work in uncompressed video mode since 1080x2400 in
RGB888 fits in the 4 DSI lanes bandwidth.
While display compression is preferred for performance and power
reasons, let's start with the uncompressed video mode support and
add the DSC support later on.

This commit fixes vertical timings of the VEC (composite output) modes
to accurately represent the 525-line ("NTSC") and 625-line ("PAL") ITU-R
standards.
Previous timings were actually defined as 502 and 601 lines, resulting
in non-standard 62.69 Hz and 52 Hz signals being generated,
respectively.
Changes to vc4_crtc.c have also been made, to make the PixelValve
vertical timings accurately correspond to the DRM modeline in interlaced
modes. The resulting VERTA/VERTB register values have been verified
against the reference values set by the Raspberry Pi firmware.

The HVS can change AXI request mode based on how full the COB
FIFOs are.
Until now the vc4 driver has been relying on the firmware to
have set these to sensible values.
With HVS channel 2 now being used for live video, change the
panic mode for all channels to be explicitly set by the driver,
and the same for all channels.

The HVS Composite Output Buffer (COB) is the memory used to
generate the output pixel data.
Until now the vc4 driver has been relying on the firmware to
have set these to sensible values.
In testing triple screen support it has been noted that only
1 line was being assigned to HVS channel 2. Whilst that is fine
for the transposer (TXP), and indeed needed as only some pixels
have an alpha channel, it is insufficient to run a live display.
Split the COB more evenly between the 3 HVS channels.

Many panel drivers define dsi_dcs_write_seq() and dsi_generic_write_seq()
macros to send DCS commands and generic write packets respectively, with
the payload specified as a list of parameters instead of using arrays.
There's already a macro for the former, introduced by commit 2a9e9daf75
("drm/mipi-dsi: Introduce mipi_dsi_dcs_write_seq macro") so drivers can be
changed to use that. But there isn't one yet for the latter, let's add it.

argument. Handle special cases in simpledrm and ofdrm. Hard-code
XRGB8888 as fallback format for cases where no given format works.
The color-mode argument accepts the same values as the kernel's video
parameter. These are mostly bpp values between 1 and 32. The exceptions
are 15, which has a color depth of 15 and a bpp value of 16; and 32,
which has a color depth of 24 and a bpp value of 32.

point a separate thread can trigger the I915_GEM_CONTEXT_DESTROY ioctl.
So we need to ensure that nothing uses the ctx ptr after this. And we

that gem_context_register() does with the ctx pointer.

There are new cases where we want to block i915 probe, such
as when experimenting or developing the new Xe driver.
But also, with the new hybrid cards, users or developers might
want to use i915 only on integrated and fully block the probe
of the i915 for the discrete. Or vice versa.
There are even older development and validation reasons,
like when you use some distro where the modprobe.blacklist is
not present.
But in any case, let's introduce a more granular control, but without
introducing yet another parameter, but using the existent force_probe
one.
Just by adding a ! in the begin of the id in the force_probe, like
in this case where we would block the probe for Alder Lake:
$ insmod i915.ko force_probe='!46a6'
v2: Take care of '*' and '!*' cases as pointed out by
Gustavo and Jani.
