Anable ACPI on Orin board

[MicroSW]

hi,

on the Orin board, I see ACPI is disabled,

linux@orin1:~$ sudo dmesg | grep ACPI
[sudo] password for linux:
[ 0.417785] ACPI: Interpreter disabled.
[ 0.578328] pnp: PnP ACPI: disabled
[ 0.732937] EINJ: ACPI disabled.

do you know it is possible to enable it on the orin board, what reason why ACPI is disabled?

NOTE: I tried to enable ACPI(device tree → ACPI) in Orin UEFI, then the board get stuck, cannot boot up,

Hi Mlinux0,

Could you help to run the following command?

 zcat /proc/config.gz|grep CONFIG_ACPI

@MicroSW

[ 0.417785] ACPI: Interpreter disabled.

It seems the expected message because it is defined in kernel/kernel-5.10/include/linux/acpi.h as default.

 #define acpi_disabled 1

@KevinFFF

CONFIG_ACPI is enabled in .config. I suspected Orin board doesn’t have this ACPI table in its firmware(UEFI). meant UEFI doesn’t pass this ACPI table to kernel, would you please double check??

[KevinFFF]

Please check the following line.
It seems the expected result if the acpi_disabled defined as 1
bus.c - drivers/acpi/bus.c - Linux source code (v5.10.104) - Bootlin

UEFI didn’t pass ACPI table to kernel, I added acpi=on in bootargs,

sudo dmesg | grep ACPI
[ 0.000000] ACPI: Early table checksum verification disabled
[ 0.000000] ACPI: System description tables not found
[ 0.000000] ACPI: Failed to init ACPI tables
[ 0.426496] ACPI: Interpreter disabled.
[ 0.585792] pnp: PnP ACPI: disabled
[ 0.740388] EINJ: ACPI disabled.

I’ve checked with our internal.
ACPI is an alternate to DTB which is used to pass platform information to the kernel.
Sorry that we don’t support ACPI in any Jetson product.
