00f5ea9fdc meson: Use dependency.partial_dependency()
It avoids calling pkg-config which was searched for in a wrong way, thus
breaking setup where unprefixed pkg-config was banned (e.g. on Exherbo).

e9add0c501 drm-shim: Let the driver choose to overwrite the first render node.
When I was writing drm-shim, I was focused on the v3d kmsro case -- use my
intel device as the kmsro display device and add on a simulator-based v3d
device that we could render with.  But for the noop backends we use for
shader-db, it's a lot more useful to just overwrite the first render node
in the system so that you don't have to pass a -d <how many render nodes I
already have in my system> argument.

5a8718f01b freedreno: Make the slice pitch be bytes, not pixels.
Back in a2xx, HW pitches were in pixels, so storing that was reasonable.
Ever since then, the HW wants pitches in bytes, and we have only one
instance of using pitch in pixels in the code (a3xx sysmem path).

Flip things around so that only a2xx has to worry about the cpp for
looking at pitches.

e4383b5c7f aco: decrease the uses of other copy operations after splitting/removing
For copies like v[7:8] = v[8:9], what currently happens is:
- do_copy() will skip the second dword
- the uses of the second dword will be reduced to 0
- the copy operation will be removed from the map
and v8 will never be set to v9.

So just decrease the uses of other operations after splitting or removing
the current operation, so: "v8 = v9" will be split off, it's uses reduced
and then the new copy will be done in the next iteration.

7f17a0a809 meson: correct windows-version define
The macro "_WINVER" does nothing, the macro definitions that matter for
windows API version selection are "_WIN32_WINNT" and "WINVER".

The header "sdkddkver.h" (which is included from thousands of
different windows-headers) defines "WINVER" to the same value as
"_WIN32_WINNT" of only the latter is defined, which explains why this
works right now. But we shouldn't depend on that kind of luck, and
instead define the right maco.

58f25098a0 radv: Use TRUNC_COORD on samplers
The default behaviour (0) is: "round-nearest-even to n.6 and drop fraction when point sampling" whereas the Vulkan spec simply wants us to floor it (1) "truncate when point sampling".

See 15.6.1 in the Vulkan spec.
https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#textures-normalized-operations

The Direct3D spec also mandates this (https://microsoft.github.io/DirectX-Specs/d3d/archive/D3D11_3_FunctionalSpec.htm#7.18.7%20Point%20Sample%20Addressing)

This fixes some point-sampling texture precision issues in some Direct3D 9 titles such as Guild Wars 2 and htoL#NiQ: The Firefly Diary that are not present on other vendors.

Fixes dEQP-VK.pipeline.sampler.exact_sampling.*

7086b38c81 radv: make sure to export the viewport index if FS needs it
If FS reads gl_ViewportIndex but VS doesn't export it, it should
be zero to avoid reading garbage.

Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/2818
Fixes: b424d49ac0 ("radv/llvm: fix exporting the viewport index if the fragment shader needs it")
