a bit delayed response: >As has been alluded to in some of Jordan Hubbard's email, Sun >Microelectronics (SME, the processor division of Sun) recently discussed >paying FreeBSD core to officially support a port of FreeBSD to SPARC. >These plans fell through in some way (I wasn't part of the discussion, so >I don't know details), but SME is having me work on the port. I'm a >full-time employee of SME, and estimate that I can spend 30-35 hours per >week of my work week on the SPARC FreeBSD porting effort (plus whatever >personal time I spend). Great! >1) Is it possible with cvsup to maintain my own source tree with my >modifications, yet stay synched with current, so that once I have the >kernel running, I can submit a single update to the current tree (or have >someone with write access do it for me)? By performing simple grep for `outb', the following files seem to include i386-specific function calls. pccard/pcic.c pci/aic7870.c pci/if_de.c pci/ncr.c pci/tek390.c pci/wd82371.c I think there need to be big change to directory structure, and we should add some wrapper function for pci bus accesses, as NetBSD does.... /sys/pci -> /sys/pci(generic) + /sys/i386/pci ? /sys/pccard -> /sys/pccard(generic) + /sys/i386/pccard ? /sys/pc98 -> /sys/i386/pc98 ? (possible?) or, /sys/arch/i386 and /sys/arch/sparc ? itojun
