Eric Anholt e3c7748b2e ci/bare-metal: Move the "POWER_GOOD not seen in time" check to the right time.
The poweron failure happens before we get to the bootloader
("load_archive: loading locale_en.bin") not after we're trying to boot the
kernel and we're waiting for the deqp run to complete.

Matt Turner 1aac47db69 Revert F16C series (MR 6774)
This reverts commit 4fb2eddfdf.
This reverts commit 7a1deb16f8.
This reverts commit 2b6a172343.
This reverts commit 5af81393e4.
This reverts commit 87900afe5b.

A couple of problems were discovered after this series was merged that
cause breakage in different configurations:

   (1) It seems that using -mf16c also enables AVX, leading to SIGILL on
   platforms that do not support AVX.
   (2) Since clang only warns about unknown flags, and as I understand
   it Meson's handling in cc.has_argument() is broken, the F16C code is
   wrongly enabled when clang is used, even for example on ARM, leading
   to a compilation error.

The gles3 and gles31 multisample and 565-no-depth-no-stencil caselists

test cases.

The remaining mustpass caselists all involve rotation, which is not
currently supported in the surfaceless deqp build.

Eric Anholt b4317fccdd ci/bare-metal: Update the kernel to msm-next-pgtables
I'd like to see this new non-UAPI feature bake in CI.  More importantly,
it may prevent some classes of flakes on cheza by isolating the processes
on the GPU so that a fault in one doesn't stomp over memory in another.
I've also pulled in a fix that etnaviv needed for their upcoming CI.

We add a few more kernel options while uprevving:

- More interconnect drivers for getting good GPU perf
- PRNG so that we don't get late-in-boot complaints about randomness.
- db820c's power domains and ethernet so hopefully we can switch to this
  upstream kernel

This seems to slightly change the flakes happening in bypass mode, so add
them to the list.

Eric Anholt d3b652f13d ci: Switch to using gold as the linker.
Debian defaults to bfd, which is comically slow.  We can't use lld because
the old version we have in the debian stable we use has various bugs.

This required bumping libwayland, which had multiply-defined symbols
issues in the previous release.

Closes: #3236

Eric Anholt 2d1c607005 ci: Make a missing device name correctly bail out of deqp-runner.sh.
If your driver is totally broken and can't even report its name, let's
stop here instead of doing a CTS run full of failure to start tests and
reporting them all missing at the end.
