I'm bringing up freedreno Vulkan on an Android phone, and my pains are
exactly what Chad said when working on Intel's vulkan for Android in
aa716db0f6 ("intel: Add simple logging façade for Android (v2)"):
On Android, stdio goes to /dev/null. On Android, remote gdb is even
more painful than the usual remote gdb. On Android, nothing works like
you expect and debugging is hell. I need logging.
This patch introduces a small, simple logging API that can easily wrap
Android's API. On non-Android platforms, this logger does nothing
fancy. It follows the time-honored Unix tradition of spewing
everything to stderr with minimal fuss.
My goal here is not perfection. My goal is to make a minimal, clean API,
that people hate merely a little instead of a lot, and that's good
enough to let me bring up Android Vulkan. And it needs to be fast,
which means it must be small. No one wants to their game to miss frames
while aiming a flaming bow into the jaws of an angry robot t-rex, and
thus become t-rex breakfast, because some fool had too much fun desiging
a bloated, ideal logging API.
Compared to trusty fprintf, _mesa_log[ewi]() is actually usable on
Android. Compared to os_log_message(), this has different error levels
and supports format arguments.
The only code change in the move is wrapping flockfile/funlockfile in
!DETECT_OS_WINDOWS, since mingw32 doesn't have it. Windows likely wants
different logging code, anyway.

We initially used this debug option to mean "don't bother registering
the OA configuration into the kernel".
This change makes this option suppress any interaction with the
i915/perf interface. This is useful when debugging self modifying
batches with performance queries while running on the intel_mi_runner.

Having to always pull the physical device from the instance has been
annoying for almost as long as the driver has existed. It also won't
work in a world where we ever have more than one physical device. This
commit adds a new field called "physical" to anv_device and switches
every location where we use device->instance->physicalDevice to use the
new field instead.

`strerror()` takes an `errno`, not the negative value returned by the
`ioctl()`.
Instead of fixing this as `"%s", strerror(errno)`, let's just use the
`"%m"` shortcut for it.
