Bug ID: 246552
Summary: aarch64 ACPI detection fails on some platforms
Product: Base System
Version: CURRENT
Hardware: arm64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: b...@freebsd.org
Reporter: greg@unrelenting.technology
On some machines, the ACPI check (`has_acpi = (acpi_find_table(ACPI_SIG_SPCR)
!= 0)` in sys/arm64/arm64/machdep.c) seems to fail — the kernel refuses to use
ACPI even with kern.cfg.order=acpi, and hardcoding `has_acpi = true` helps.
Confirmed on two devices now:
- Raspberry Pi 4 https://github.com/pftf/RPi4 (by me)
- SolidRun HoneyComb LX2K / CEX7 module (NXP Layerscape LX2160A)

They *do* have the SPCR table of course.
