This reverts commit 4e1bbb000c. It turns
out that some DXVK apps due to some implementation detail of DXVK or
other create and destroy instances in an interleaved way. Freeing the
glsl_type memory without being a bit more careful causes use-after-free
issues. Looks like we need to try again.
When the host is running on softpipe/llvmpipe the maximum number of
samples for multisampling is 1. GL 3.0 requires at least 4 samples, and
softpipe/llvmpipe get around this by enabling PIPE_CAP_FAKE_SW_MSAA.
This patch mimics softpipe/llvmpipe behavior in virgl by enabling the
same PIPE_CAP_FAKE_SW_MSAA workaround when the max sample count reported
by the host is 1. This change allows virgl on a softpipe/llvmpipe host
to advertise support for GL 3.0 and beyond.

This patch refactors a substantial amount of code in preparation for
mipmaps. In particular, we know have a correct slice abstraction based
on offsets; cpu/gpu are no longer arbitrary pointers. We additionally
shuffle around other code to accompany these changes and cleanup how
tiled textures are handled, while drawing some attention to the blit
code.
Mipmaps are still disabled at this point, as autogeneration is not yet
implemented; enabling as-is would cause regressions.

Although this is not functional (and the command stream side is not
aiming for ES3 right now), this is enough to run dEQP-GLES3 shader
tests with the version override directive; this is useful, as some ES3

On Midgard, float ops support standard source modifiers (abs/neg) and
destination modifiers (sat/pos/round). Integer ops do not support these,
however. To cope, we use native NIR source modifiers for floats, but
lower them away to iabs/ineg for integers, implementing those ops
simultaneously to avoid regressions.

Some of these are not yet fully functional due to related bugs, but this
the correct op mapping. The native ball/bany opcodes act on vec4's
unconditionally. That said, both ball and bany have the nice property
that duplicating an argument does not affect their output, so the
default "hanging swizzles" allow us to implement 2/3-component opcodes
correctly, implicitly lowering.

This gets the basevertex from the draw depending on whether
it's an indexed or non-indexed draw.
We still fail a transform feedback test for vertex id, as
the vertex id actually an index id, and isn't getting translated
properly to a vertex id, suggestions on how/where to fix that welcome.

From "Alpha Coverage" section of SKL PRM Volume 7:
"If Pixel Shader outputs oMask, AlphaToCoverage is disabled in
hardware, regardless of the state setting for this feature."
From OpenGL spec 4.6, "15.2 Shader Execution":
"The built-in integer array gl_SampleMask can be used to change
the sample coverage for a fragment from within the shader."
From OpenGL spec 4.6, "17.3.1 Alpha To Coverage":
"If SAMPLE_ALPHA_TO_COVERAGE is enabled, a temporary coverage value
is generated where each bit is determined by the alpha value at the
corresponding sample location. The temporary coverage value is then
ANDed with the fragment coverage value to generate a new fragment
coverage value."
Similar wording could be found in Vulkan spec 1.1.100
"25.6. Multisample Coverage"
Thus we need to compute alpha to coverage dithering manually in shader
and replace sample mask store with the bitwise-AND of sample mask and
alpha to coverage dithering.
The following formula is used to compute final sample mask:
m = int(16.0 * clamp(src0_alpha, 0.0, 1.0))
dither_mask = 0x1111 * ((0xfea80 >> (m & ~3)) & 0xf) |
0x0808 * (m & 2) | 0x0100 * (m & 1)
sample_mask = sample_mask & dither_mask
Credits to Francisco Jerez <currojerez@riseup.net> for creating it.
It gives a number of ones proportional to the alpha for 2, 4, 8 or 16
least significant bits of the result.
GEN6 hardware does not have issue with simultaneous usage of sample mask
and alpha to coverage however due to the wrong sending order of oMask
and src0_alpha it is still affected by it.
