intel/iris: Always initialize CCS to 0
Previously, we were initializing the CCS to 0xFF for MCS+CCS due to a
misunderstanding of the following lines in the bspec:
The following are the general SW requirements for MCS buffer clear
functionality:
...
- If Software wants to enable Color Compression without Fast
clear, Software needs to initialize MCS with zeros.
- Lossless compression and CCS initialized to all F (using HW
Fast Clear or SW direct Clear) on the same surface is not
supported.
The first line does not refer to the CCS as the comment author supposed
but refers to the MCS as the comment says. It means that if you want to
use MCS compression without a fast-clear, you should initialize the MCS
to 0x00. This is because the value 0x00 in the MCS means "all data is
in plane 0" which is a perfectly valid non-fast-clear initialization.
It's also the value the MCS should be in if you do a RECTLIST slow-clear
where the primitive fully covers each pixel such that the same value is
written to all samples.
The second line in the above quote seems to imply that CCS fast-clear is
incompatible with MCS fast-clear. In particular, MCS+CCS fast-clear
uses a 0xff value in the MCS (like on Gen7-11) and leaves the CCS in
either the compressed or the pass-through state. Therefore, we should
initialize the CCS to 0x00 even for MCS+CCS surfaces.

anv: Swizzle fast-clear values
Starting with Gen12, we can fast-clear a lot more surface formats and we
are suddenly in the position of having to fast-clear surfaces with
formats with an implicit swizzle such as VK_FORMAT_R4G4B4A4_UNORM_PACK16
which is represented as ISL_FORMAT_A4B4G4R4 with a BGRA swizzle. In
order for blorp to do the fast-clear color conversion for us, it needs
a properly swizzled color.
This fixes the following Vulkan CTS groups on TGL:
- dEQP-VK.pipeline.blend.format.b4g4r4a4_unorm_pack16.*

soft-fp64: Split a block that was missing a cast on a comparison
This function has code like:
if (0x7FD <= zExp) {
if ((0x7FD < zExp) ||
((zExp == 0x7FD) &&
(0x001FFFFFu == zFrac0 && 0xFFFFFFFFu == zFrac1) &&
increment)) {
...
return ...;
}
if (zExp < 0) {
I saw that, and I thought, "Uh... what? Dead code?" I thought it was a
bit fishy, so I grabbed the Berkeley SoftFloat Library 3e code, and
there is similar code in softfloat_roundPackToF64
(source/s_roundPackToF64.c), but it has an extra (uint16_t) cast in the
first comparison. This is basicially a shortcut for
if (zExp < 0 || zExp >= 0x7FD) {
So, having the nesting kind of makes sense. On a CPU, nesting the flow
control can be an optimization. On a GPU, it's just fail. Split the
block so that we don't need the uint16_t cast magic.

This occurs in a handful of places in the soft-fp64 code, and that is
the primary reason for the change.
Perhaps the patterns that generate umin should be conditioned on
something, but I'm not sure what. lower_bitops might cover the cases
that matter, but it seems ugly.

lima: implement zsbuf reload
Fragment shader can write depth and stencil if we set necessary flags
in RSW. In addition to that we need to use special format for Z24S8.
Original format is apparently Z24X8 since we can't sample stencil in GLES2.
This new format also seems to use several components for storing depth
since we saw r != g != b when sampling with this format.
[vasily: - initialize clear->depth to 0xffffff if we reload depth, just
like blob does. Reloading doesn't work otherwise
- use single bitmap for reload type]
