The apm_bios interface is not exactly a paragon of good design: it's only become as widespread as it has by historical accident, it represents a weird in-kernel combination of IPC and actual hardware control, and it isn't available cross-platform in any reliable fashion. Rather than seeking to perpetuate the use of /dev/apm_bios by random applications, I think we should encourage other distros to follow FSO's example and replace it with other mechanisms that are better suited to the 21st century. If we could standardise on a single D-Bus API for user-facing power management, with some kind of daemon responsible for arbitrating those requests and converting them into whatever operations are most suitable for the underlying kernel support (which might be /dev/apm_bios in some circumstances) then that would be perfect. p. _______________________________________________ Openembedded-devel mailing list [email protected] http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel
