llvmpipe: enable GL compatibility profiles

The two rasterpos fails looks related to GLSL linking, the vertex
shader is linked with the geometry shader which doesn't use any
of it's outputs so they seem to get removed, which stops the rasterpos
from working.

This refactors out the vertex color clamping from the VS shader,

panfrost: Rewrite the clear colour packing code

At the beginning of a render pass, the hardware will fill the tilebuffer
with an arbitrary 128-bit word. To implement colour clears, the driver
must pack the API-specific clear colour according to the 128-bit layout
of the tilebuffer. This layout depends only on the render target format.

The existing code to handle this was based on loose guesswork. It works
for the format / clear colour combinations tested in dEQP-GLES3, but it
is severely deficient in the general case.  It works by matching on the
PIPE format of the render target (not the layout of the tilebuffer). For
special cased PIPE formats, it open codes a buggy pack routine.
Otherwise, it defaults to util_pack_color in the hope that will work.
Since util_pack_color doesn't know anything about Mali tilebuffer
layouts, that means it's defaulting to wrong behaviour.

Now that we understand internal tilebuffer layouts, let's rewrite the
packing code. Instead of matching PIPE formats, map the PIPE format to
the internal tilebuffer layout using the common table, ensuring the
mapping remains in sync with the render target descriptor. Then for
blendable tilebuffer formats, pack using a common float -> fixed point
path supporting optional sRGB translation. Raw formats use
util_pack_color as before.

For formats with less than 8 bits per channel, the new code uses the
fractional bits of the fixed-point representation. This is required for
correct dithering if the clear colour is not exactly representable in
the final low precision format.

In summary, at least the following bugs in the old code are fixed:

   * Swapped R/B channels with sRGB
   * Swapped R/B channels with some missing formats
   * Incorrect dithering with RGB565, RGB5_A1

Fixes the following test cases:

   dEQP-EGL.functional.wide_color.window_8888_colorspace_srgb
   dEQP-EGL.functional.wide_color.pbuffer_8888_colorspace_srgb
   dEQP-EGL.functional.wide_color.window_888_colorspace_srgb
   dEQP-EGL.functional.wide_color.pbuffer_888_colorspace_srgb

Later in the series, unit tests are added for the new implementation.

panfrost: Fix leak of render node fd

Transfer ownership of the render node fd to the panfrost_device (minor
change to panvk), and then close the file descriptor for the render node
bound to the panfrost_device when destroying the panfrost_device. Of all
the users of panfrost_open_device, panvk is the only one that correctly
closed the fd before. Accordingly, this fixes an fd leak in the Gallium
driver (and performance counter utilities).

This fix still applies to the Gallium driver when renderonly is in use--
although renderonly closes its own fd, the fd is _duplicated_ in
panfrost_drm_winsys.c, so renderonly and panfrost must _both_ close
their respective fd to fix the leak.

This fixes a crash when running dEQP-EGL for more than two hours.
dEQP-EGL creates a new screen for every test case and then immediately
destroys it. If destroying a screen leaks the fd, this causes the number
of open file descriptors to increase monotonically until the process
ends. This will eventually hit the system limit for number of open files
and abort the process.

This bug was identified while attempting to run the OpenGL ES
conformance tests via cts-runner, and then confirmed with `lsof`. With
the fix, the number of file descriptors reported by `lsof | wc -l` is
now constant while running dEQP-EGL as expected.

vulkan/wsi/wayland: always initialize format vector

In wsi_wl_display_init(), the format vector is initialized only when the
caller sets the function to query the formats/modifiers. But
wsi_wl_display_finish() always release the vector, no matter if it has

For now it just works because the u_vector_foreach() macro works when

Fortunately, there's a new kernel API for this: the I915_USERPTR_PROBE

iris: Don't try to CPU read imported clear color BOs

Previously, when importing a resource with modifiers that include
clear color as auxiliary data, we were mapping the clear color BO
on the CPU in order to set res->aux.clear_color to the value stored
there.

We are generally trying to avoid CPU mapping imported buffers, because
in hybrid setups, they could be from a different device, and may not be
mappable.  So we'd like to avoid that here.

This CPU-side knowledge of the clear color is only used in a few cases:

1. Avoiding a resolve due to a partial clear with a changing clear color

2. Avoiding disabling CCS when rendering to a texture view of a resource
   where the only format difference is sRGB vs. linear and the clear
   color is 0/1.

Instead of mapping the clear color BO on the CPU, we instead set a flag
indicating that we don't know the clear color, and reset it to known on
our first clear.

In the first case, the first partial fast clear of a resource would eat
an extra resolve (there is no penalty if we clear the whole resource).

The second case doesn't seem that critical, as it's someone rendering
to an imported BO - when the common case is to texture from it.
