Here's "just compiles and works for me" patch, in case someone need them,
to bring the tools from recent FreeBSD-CURRENT, add /dev/acpi to /dev/MAKEDEV
for acpiconf, and update /etc/rc.suspend and /etc/rc.resume .
$ fetch http://les.ath.cx/DragonFly/in-tree-acpicatools.patch.gz
$ zcat in-tree-acpicatools.patch.gz | patch -d /usr/src -p0
The tools won't get built during buildworld since the patch doesn't add
acpi/ to SUBDIR list in usr.sbin/Makefile.
The acpiconf command invokes /etc/rc.suspend and /etc/rc.resume;
you'll see strange warnings unless you install these two scripts.
TODO/BUGS:
- bring in other endian-related functions from FreeBSD-CURRENT
and clean up the borrowed functions in acpiconf/acpi.c .
- move the following stuffs from /sys/dev/acpica5/Makefile into
Makefile.inc in the same directory, so that we can share the
definitions between acpi modules and tools:
.PATH, include paths, list of ACPI-CA source codes (SRCS+= lines),
make rules for modified version of acpi.h and acenv.h
- if you run `acpiconf -d', `acpiconf -e' or `acpiconf -s' no longer
works unless you reboot. `acpiconf -e' after `acpiconf -d' fails
with a warning:
acpi0: interrupt handler already installed
ACPI-0210: *** Error: Unable to install System Control Interrupt Handler, AE_ALREADY_EXISTS
