We're not *quite* ready to open the flood gates on Bifrost (a major
blocker is CI, which is itself blocked on the lockdowns - expected to be
resolved in the coming months..)
Nevertheless, let's add a debug option to probe on compatible Bifrost
devices to avoid keeping out-of-tree patches around.

We don't force w=1 for Bifrost textures. We already compose this into
the swizzle as necessary, so we can just ignore this field I think. But
let's identify it so we don't forget what it is.
The blob uses it to force w=1 for <= 3-channel formats (0x10), as well
as a flag to swap r/b for BGRA (0x4). There are probably other flags
here but it doesn't.. really matter to us.

It doesn't make sense to munmap/mmap repeatedly; they're mapped GPU-side
anyway. So just munmap on free, which will happen in low-mem regardless.

Rather than heuristically guessing what PIPE formats correspond to what
in the hardware, hardcode a table. This is more verbose, but a lot more
obvious -- the previous format support code was a source of endless
silent bugs.

Similar to what the blob does. My reason for doing this was mainly so
traces weren't as different, which makes it more work to spot

Now that its Gallium dependencies have been resolved, we can move this
all out to root. The only nontrivial change here is keeping the
pandecode calls in Gallium-panfrost to avoid creating a circular
dependency between encoder/decoder. This could be solved with a third
drm folder but this seems less intrusive for now and Roman would
probably appreciate if I went longer than 8 hours without breaking the
Android build.

These two cases were flipped from the notes, leading to underestimates
of the padded vertex count, manifesting as visual corruption (random
geometry messed up). This issue was raised when noticing the corruption
went away when dramaticlaly oversizing max_index on an instanced indexed
draw, and then checking that padded_count >= vertex_count -- which
turned out *not* to be the case on certain inputs, a clear issue. Hence
looking into this routine...

Rather than creating partially within the Gallium create function and
monkeypatching on draw time with code split across N different files
with tight Gallium dependencies, let's streamline everything into a
series of maintainable routines in mesa/src/panfrost with no Gallium
dependencies, doing the entire texture creation in one-shot and thus
adding absolutely zero draw-time overhead (since we can allocate a BO
for the descriptor and upload ahead-of-time, so switching textures is as
cheap as switching pointers).
Was this worth it? You know, I'm not sure :|

It's a complicated story. But from what I can tell, in GL compute
without barriers, the blob is able to redistribute the workgroups in
various ways (that are not yet understood), whereas with barriers it
cannot redistribute anything, which accounts for erratic workgroup
packing without barriers.

There's only one way to encode comparison functions in the command
stream, not two. It's just that the semantics for texture comparisons
are flipped from the semantics of stencil comparison. We can factor out
that flip to common Panfrost code, rather than tying it to a second
Gallium routine.

It shows up as a special (magic?) attribute. We could try to be clever
and only include the extra record if gl_VertexID is actually read, but
honestly that's just extra complexity for no good reason. Might as well
just always include it; this won't be a real bottleneck, I don't think.

Padded counts are numbers of the form:
n = (2k + 1) * 2^s
for k, s integers. Rather than explicitly store k and s separately and
then compute this formula on demand, it's much cleaner to store the
padded number itself, which is what you manipulate most of the time.
When you do need k,s it is easy to factor by noticing the bitwise
representation:
s = ctz(n)
k = n >> (s + 1)
