Midgard has multiple Surface Descriptor formats selectable in the texture
descriptor. Previously, we have used both the "64-bit surface descriptor" and
the "64-bit surface descriptor with 32-bit line stride and 32-bit layer stride".
A delicate routine tried to guess what stride the hardware will use if we don't
specify it explicitly, and omit the stride if it matches. Unfortunately, that
routine is broken in at least two ways:
* Textures with ASTC must always specify an explicit stride. Failing to do so
(like we were doing) is invalid.
* It applies even for interleaved textures. The comment above the function
saying otherwise is incorrect. (TODO: double check this)
Bifrost onwards always specify the strides explicitly. Let's just do that and
unify the gens. What is lost from doing this? A ludicrously trivial amount of
memory and texture descriptor cache space. 8 bytes per layer*level per texture,
in fact. Compared to the size of the textures being addressed, the memory usage
is trivial. The texture descriptor cache size maybe matters more. But given
Arm's hardware people went this direction for Bifrost and stuck to it, I doubt
it matters much.

Before we used GenXML, pan_texture mixed layout code with texture descriptor
packing code. For the most part, the layout code is generation-independent; the
pack code is not. We introduced an anti-pattern where the file was compiled N+1
times: N times for each PAN_ARCH value, and an extra time with no PAN_ARCH
value. And then the contents of the file changed completely depending on
PAN_ARCH. This is a pretty weird construction.
Let's instead split off the layout file from the descriptor file, compile the
layout file once, and compile the descriptor file per-gen.

Most of the time when the logging code is invoked, it means we're
already in an edge case. It should be as robust as possible, otherwise
we risk making hard to debug things even harder. To that end, instead
of blowing up if passed a NULL object on the list, handle it as
gracefully as we can.

Instead of being globbed into the RSD, Valhall uses minimal shader program
descriptors. For IDVS, we need separate descriptors for position and varying
shaders. It's actually worse -- we need separate descriptors for drawing points
and drawing lines/triangles in order to skip over the gl_PointSize write. Adapt
prepare_shader to upload all these descriptors.

Either as uniform remap table entries on Bifrost, or as simple buffer
descriptors on Valhall. The underlying hardware is different (and there are
compiler changes for load_ubo handling), but the high level UBO upload logic
does not have to care about that.

On Valhall, the fragment shader differs based on whether IDVS or the legacy
geometry flow is used be. In particular, varyings are accessed differently.
We use the legacy geometry flow for blitting on all GPUs, so indicate this in
the shader inputs.

Required to query texture features on Valhall. It's technically the same as
previous Malis (except for narrow ASTC), but conceptually it's different as
plane descriptors have superseded indexed pixel formats for block compressed
textures.

My understanding of the signal masks is that they control what stages
must complete before the semaphore is signaled. Using 0 theoretically
means the semaphore could be signaled immediately without waiting on
anything. Use ~0 instead to say it depends on everything.

Without this we might choose 8 or 16 width, while the app assumes 32.
With subgroup operations it may cause wrong calculations and thus bugs.
Examples of such games are Aperture Desk Job and DOOM Eternal.
v2: Make it a driconf option instead of applying unconditionally, move
from brw_required_dispatch_width to brw_compile_cs
v3: Rename allow_assuming_full_subgroups -> assume_full_subgroups.
Include assume_full_subgroups value in anv_pipeline_hash_compute().
v4: Move actual workaround code from brw_fs.c -> anv_pipeline.c.

SVGAv3 changes the PCI id due to differences in how PCI configuration
is handled - removal of VRAM and FIFO PCI resources, switch to MMIO
registers and MSI/MSI-X IRQ support but the 3D commands remain largely
the same.
This enables 3D/graphics acceleration support on SVGAv3.

SVGA device always supports direct maps which are preferable in all cases
because they avoid temporary surfaces and extra transfers. Furthermore
DMA transfers on devices with GB objects have undefined timing semantics.
Also the DMA transfers can not work on SVGAv3 because the device lacks
VRAM to be able to perform them.
Fix the last paths still using DMA transfers to make sure they're never
used on GB enabled configs. This fixes gnome-shell startup on SVGAv3.

Flushing the command queue before mapping a resource is not enough
to guaruantee that the mapped content is not stale. We have to finish
to make sure that the gb readback actually updated the guest surface.
This fixes races in direct maps (map reads raced with gb readbacks)
