The table describes how each bit in the u64 value is used. Explicitly
state which values a field can take if we have defines for them. Also
add a note when a field isn't always populated.
Forcing people to update the table when changing the bit layout should
make it more obvious when there's a mistake, I hope.
If we get to the point where the bit layout gets more complicated, it
might be worth it to split the table into multiple tables (e.g. one for
GFX8, one for GFX9+, and so on).

The DCC_MAX_COMPRESSED_BLOCK has to contain one of
AMD_FMT_MOD_DCC_BLOCK_* and with 3 values this doesn't
fit in 1 bit.
Fix this cleanly while it is only in drm-next.

Pull char/misc fixes/removals from Greg KH:
"Here's some small fixes for 5.10-rc2 and a big driver removal.
The fixes are for some reported issues in the interconnect and
coresight drivers, nothing major.
The "big" driver removal is the MIC drivers have been asked to be
removed as the hardware never shipped and Intel no longer wants to
maintain something that no one can use. This is welcomed by many as
the DMA usage of these drivers was "interesting" and the security
people were starting to question some issues that were starting to be
found in the codebase.
Note, one of the subsystems for this driver, the "VOP" code, will
probably come back in future kernel versions as it was looking to
potentially solve some PCIe virtualization issues that a number of
other vendors were wanting to solve. But as-is, this codebase didn't
work for anyone else so no actual functionality is being removed.
All of these have been in linux-next with no reported issues"

This adds modifiers for GFX9+ AMD GPUs.
As the modifiers need a lot of parameters I split things out in
getters and setters.
- Advantage: simplifies the code a lot
- Disadvantage: Makes it harder to check that you're setting all
the required fields.
The tiling modes seem to change every generation, but the structure
of what each tiling mode is good for stays really similar. As such
the core of the modifier is
- the tiling mode
- a version. Not explicitly a GPU generation, but splitting out
a new set of tiling equations.
Sometimes one or two tiling modes stay the same and for those we
specify a canonical version.
Then we have a bunch of parameters on how the compression works.
Different HW units have different requirements for these and we
actually have some conflicts here.
e.g. the render backends need a specific alignment but the display
unit only works with unaligned compression surfaces. To work around
that we have a DCC_RETILE option where both an aligned and unaligned
compression surface are allocated and a writer has to sync the
aligned surface to the unaligned surface on handoff.
Finally there are some GPU parameters that participate in the tiling
equations. These are constant for each GPU on the rendering/texturing
side. The display unit is very flexible however and supports all
of them :|
Some estimates:
- Single GPU, render+texture: ~10 modifiers
- All possible configs in a gen, display: ~1000 modifiers
- Configs of actually existing GPUs in a gen: ~100 modifiers
For formats with a single plane everything gets put in a separate
DRM plane. However, this doesn't fit for some YUV formats, so if
the format has >1 plane, we let the driver pack the surfaces into
1 DRM plane per format plane.
This way we avoid X11 rendering onto the frontbuffer with DCC, but
still fit into 4 DRM planes.
