Because these formats are introduced trough an extension, their
enum values are exceedingly large and we cannot use them to index
directly into the format table we had for core formats. Instead,
we put these in a separate table and we always use the
VK_ENUM_OFFSET helper to index into these tables.

- gen4 - has dp4acc and dp2acc, dp4acc is used to implement
4x8 dot product.
- gen3 - has dp2acc, in OpenCL blob uses dp2acc for dot product
on both get3 and gen4.
- gen2 - unknown, lower everything.
- gen1 - no dp2acc, lower everything. OpenCL blob doesn't advertise
cl_qcom_dot_product8 but still generates code for it.
The assembly is more verbose and uses yet to be documented
mad32.u16 instruction.
Passes:
dEQP-VK.spirv_assembly.instruction.compute.opsdotkhr.*
dEQP-VK.spirv_assembly.instruction.compute.opudotkhr.*
dEQP-VK.spirv_assembly.instruction.compute.opsudotkhr.*

dEQP-VK.spirv_assembly.instruction.compute.opudotaccsatkhr.*
dEQP-VK.spirv_assembly.instruction.compute.opsudotaccsatkhr.*
Only packed 4x8 unsigned and mixed versions are accelerated.
However in theory we should be able to do better for signed version
than current NIR lowering.

Softpipe was the only driver still using this feature. I had enabled it
in ba22f014f9 ("softpipe: Enable PIPE_CAP_TGSI_ANY_REG_AS_ADDRESS;") for
an instr count win, but it's really not important to that driver and it's
not worth keeping the knob around just for that.

We don't plan to support NV_mesh_shader officially on RADV,
because it performs poorly on AMD hardware. However, we are
implementing this extension to get some experience with mesh
shader technology.
Users should not rely on this support because we are going
to remove it if/when a potential cross-vendor extension appears.

There exists hardware intel gen4 specifically that has only 6 clip planes
but supports GLSL 1.30. This enhances the CAP so that the current values
of 0,1 remain the same, but giving it a larger number will override the
max.
This allows the gen4 intel to set this to 6 and leave everyone else alone.

This was useful for emulating GL 3.2 in virgl on a GLES3 host renderer,
before GL_EXT_depth_clamp introduced the ability for hardware drivers to
expose the feature on GLES. Now that we have that, the desktop-GL-capable
HW that virgl cares about can expose desktop GL even on its GLES renderer
on the host without this emulation. I don't think anyone particularly
cares about hitting higher GL versions on actually-core-GLES hosts with
virgl.

It's a *long* time since SGI was the copyright holder for the OpenGL
trademark. And we implement more APIs by now, so let's update the
disclaimer to instead redirect to the Khronos licensing page for
details.
While we're at it, soften the language on legal status as a formal
implementation, as we currently have conformant drivers for most of the
APIs by now. But refer to the Khronos website for details, as
conformance status for drivers are subject to change.

When using the Vulkan API, command buffers can be recorded way before
perfetto is enabled. This can be problematic if you want already
recorded command buffers to produce traces.
This new environment variable makes perfetto enabled internally so
that command buffers are recorded with timestamps, even though no
perfetto recording happens.

It was a bit trickier to RE, since blob doesn't expose this
functionality at all, however we had a clue from the very beginning:
lima_blend_factor is 3 bits, i.e. 8 values, but only 5 of them were
used, it just waited till someone tried what 3 unused values do.
Interestingly enough, it turns out "5" works just as "0" (which is
PIPE_BLENDFACTOR_*SRC_*), but only if output register for gl_FragColor
is $0, So it looks suspiciously similar with PIPE_BLENDFACTOR_*SRC1_*
behavior, and looks like secondary output is taken from $0.
Since output regs for all other outputs are configured via RSW, there
must be a field in RSW for output register for secondary color, it's
likely 4 bits and it's currently set to 0 for reg $0.
Then it was just a matter of brute-forcing various consecutive 4 bits
in RSW - and indeed, setting top 4 bits of rsw->aux0 to the index of
gl_FragColor output register fixes blending tests when we use "5"
blend factor instead of "0".
So it must be a register number for gl_SecondaryFragColor. Unlike
gl_FragColor, the field is only repeated once in RSW.
Wire it up in compiler, and piglit arb_blend_func_extended now passes.
