This handles the usual case. 8-bit register access parallels 16-bit
access, but with one major caveat: in 8-bit mode, only half of the
register file is actually (directly) accessible as sources. In
particular, for each 16-bit integer register (hrN), we can only index a
*single* 8-bit integer (qrN), corresponding to the lower 8-bits. To get
the upper 8-bits, it is required to do an explicit shift. For example,
to add the bytes of a 16-bit integer hr0.x and get the result as an
8-bit qr0, you'd need to do something like:
ilsr hr1.x, hr0.x, #8
iadd qr0.x, qr0.x, qr1.x
This scheme diverges from 32-bit registers, in that both the upper and
lower halves of a 32-bit register are individually accessible as a pair
of half registers. For contrast, to add the lower and upper 16-bits of a
32-bit integer r0.x, you can just:
iadd hr0.x, hr0.x, hr1.x
Since hr1.x = upper 16-bit of r0.x.

Since it is dependent on the tile mode (ie. disabled for smaller mipmap
levels), we should handle it a similar way to fd_resource_level_linear().
The code previously mostly did the right thing because the old helper
took the tile mode.

Best to keep it encapsulated in the helper which returns layer/level
offset (and actually use that helper everywhere) rather than spreading
the logic around the code.
Also add a helper to find UBWC offset, to complete the encapsulation.

If someone is importing a buffer, we can't really know the state of it's
contents, so assume it is valid.
Signed-off-by: Rob Clark <robdclark@chromium.org>
There are still some fallbacks we'll need to handle before we can enable
UBWC by default. I think we may need to fallback to uncompressed if
image atomic operations are used. And we still need to sort out how to
handle image and sampler views of compressed resources if the image/
sampler view is using a format that does not support compression. (I
think the latter should hopefully be uncommon outside of deqp/piglit.)
But at least this gets us to the point where supertuxkart works properly
with UBWC enabled ;-)

A few fixes that get UBWC working for the games/benchmarks where I
noticed problems before (in particular and manhattan, and stk (modulo
image support for UBWC when compute shaders are used for post-process
effects):
+ fix the size of the UBWC meta buffer (ie, the offset to color
pixel data) that is returned by ->fill_ubwc_buffer_sizes()
+ correct size/layout for 8 and 16 byte per pixel formats
+ limit the supported formats.. Note all formats that can be
tiled can be compressed.

Now that dlist compilation again knows if it is inside glBegin/glEnd,

We have to use _mesa_inside_dlist_begin_end instead of
_mesa_inside_begin_end to see if we are inside a glBegin/glEnd block in
case of display lists.
So split the is_vertex_position function used in vertex attribute processing
into a imm and dlist variant and use the appropriate _mesa_inside_begin_end

This new pass (which isn't even compile-tested) attempts to determine
the ALU type of all the SSA values in a function impl. It takes a
greedy approach and assigns intness or floatness to everything it thinks
can possibly contain an int or a float. Some values will be labled as
both int and float and some will be labled as neither and it is up to
the caller to decide what to do with this information. However, for a
"nice" shader where the original source contained no bit-casts and no
implicit bit-casts were introduced by optimizations, there shouldn't be
any overlap in the two sets save for the odd CSEd zero constant.

These add a lot of complexity, and I currently can't measure any
performance benefit from having them. In the past, I seem to recall
seeing a benefit in drawoverhead scores, but currently it looks like
dropping them is either a wash or 1-2% faster.
Drop them to simplify allocations.
The STATE_BASE_ADDRESS "Size" fields can only hold 0xfffff in pages,
and 0xfffff * 4096 = 4294963200, which is 1 page shy of 4GB.
So we can't use the top page.

st/mesa's PBO upload path binds a vertex shader that doesn't use any
textures, but leaves the existing sampler views bound in place. This
was tricking us into thinking the PBO destination might be bound for
texturing in some cases. In Civilization VI, this fixes a false self-
dependency issue that was preventing CCS_E compression on upload.
Fixing this slightly improves frame times.
