Graphics driver and CONFIG_ACPI

[Riza Dindir <riza.dindir%gmail.com@localhost>]

Hello,

I am trying to make the radeonr7 m265 display device to work on NetBSD
9.2 (amd64). In the radeon_bios.c file there is a definition used,
named CONFIG_ACPI. Some functions are using this definition. I want to
enable this. Where can I do this? In the configuration file (GENERIC
for instance) or someplace else?

Regards
Riza
