OpenBSD/hppa

• HP PA-RISC 7100, 7150, 7100LC, 7200 processors (7300 and 7300LC may work too);
• Viper (others ?) memory controller;
• LASI, ASP, WAX GSC bus controller;
• and EISA bus controller;
• NCR53C700, NCR53C710, NCR53C720 SCSI I/O Processor;
• Venom, CRX-8, CRX-24, HCRX-8, HCRX-24 video controllers;
• HIL or PS/2 keyboard and mouse;
• EISA devices will work, but they won't be usefull for booting, but those manufactured by HP for 700/800 systems.

• HP 9000 834, 835, 836, 844, 845, 846;
• HP 9000 E23, E35, E45, E55;
• HP 3000 908, 918, 928, 938;
• Hitachi VQ200, VQ210, and some workstations;
• Precision Book from RDI Computer Corporation (well, unlikely)
• HP VME and VXI single board systems (requires VME at least)

Status:

History:

• LASI, ASP, WAX and EISA bus adapters
• com, lpt, fdc drivers (no fd yet ;)
• PDC driver
• kernel bootstrap working
• network boot working through the LIF image
• cross-tools compiling/working

Build cross-tools:

cd /usr/src
sudo make TARGET=hppa cross-tools

cross-tools build process may fail in the libc stage, consider that's all right, since libc support is not finished yet.

Build boot.lif file using cross-tools:

cd /sys/arch/hppa/stand
make obj
set cross=(/usr/cross)
make MACHINE=hp700 MACHINE_ARCH=hppa \
	"AS=$cross/hppa/usr/bin/as" "CC=$cross/hppa/usr/bin/cc" \
	"CPP=$cross/hppa/usr/bin/cpp" "LD=$cross/hppa/usr/bin/ld" \
	"AR=$cross/hppa/usr/bin/ar" "STRIP=$cross/hppa/usr/strip" \
	"LORDER=$cross/hppa/usr/bin/lorder" "NM=$cross/hppa/usr/bin/nm" \
	"RANLIB=$cross/hppa/usr/bin/ranlib" "SIZE=$cross/hppa/usr/bin/size"

One will have a boot.lif file to boot then in the obj-directory. That image may include diskless kernel image if one was available in the sys/arch/hppa/compile/DISKLESS/bsd.
Kernel cross-build process is similiar to the one for boot, consult config(8) and options(8) for kernel build options and configuration.
