Hi, merging the code from ACPI For FreeBSD project into CURRENT finished! We would very much appreciate for all people who encouraged and helped and supported us. 1. Using ACPI If you have machines with ACPI BIOS, you should be able to power off the machine by shutdown -p (or acpiconf -s 5), or the power button is pressed if the machine support it. This is one of the power management features covered by ACPI. The implementaion of PnP configuration, processor control and thermal management features will come later. To activate acpi driver, just add device acpi in your kernel configuration file. Also you maybe interested in options ACPI_DEBUG options AML_DEBUG to watch the ACPI events and trace of AML interpreter. 2. Further development We, ACPI project guys, will stop maintaining own CVS repo. except for ACPI DSDT (Differentiated System Description Table) data file and ASL (ACPI Source Language) file collection. We're going to concentrate our development on -CURRENT. Because it is still in experimental phase, more developers are needed. To avoid making duplicate effort, I'd like to propose that having an announcement in -current (or -hackers?) ML first then starting your development. Watanabe-san and Yokoyama-san are working on GPE (General Purpose Event) handling, I myself (iwasaki) working on PowerResource implementaion for now. # Battery, Thermal management would be good candidates for your first trial. 3. ACPI data file collection The DSDT/ASL collection is available at http://www.jp.freebsd.org/cgi/cvsweb/ACPI/util/takawata/acpi/?cvsroot=freebsd-jp http://www.jp.freebsd.org/cgi/cvsweb/ACPI/util/dfr/acpitest/?cvsroot=freebsd-jp Note: this URL maybe change in the near future. If your machine has ACPI BIOS, please send us ({iwasaki|takawata}@FreeBSD.org) obtained data files as follows; # acpidump -o foo.dsdt > foo.asl 4. Information about ACPI http://www.teleport.com/~acpi/ has enough information about ACPI including links. It seems ACPI 2.0 Specification is now available for download from this site. I put diffs between 1.0b and 2.0 index with a little modification for your convenience at http://people.freebsd.org/~iwasaki/acpi/spec-index.diff Have fun! and Thanks!
