OpenBSD added initial support for Qualcomm Snapdragon Elite X after 1 day

When a new processor is released, how long would you expect it to take before your favorite operating system adds support for it?

In the case of OpenBSD/arm64, the time lag can occasionally be measured in days if not hours.

In a recent message to tech@, Patrick Wildt (patrick@) premiered the patch to add support for the Qualcomm Snapdragon Elite X processor the day after it was officially released.

Patrick's message reads,

Hi there,

the Qualcomm Snapdragon Elite X machines were released yesterday, I got
a Lenovo Yoga Slim 7 today, and it's already booting up with working
NVMe, USB and keyboard.  Wonder if I beat my last record.

This is focused on ACPI mode, which we will only make use of until we
can switch to device trees.  The GIC bits will require some additional
work, but hey, it's day 1.

Cheers,
Patrick

followed by the code to implement initial support for the new chip.

A series of commits followed, and the result should be in OpenBSD/arm64 snapshots by the time you read this.

If you can get your hands on the hardware, please dive in and test!
