Computer (mainly NetBSD)

This page contains IEEE 1394 isochronous data hander for NetBSD and New CardBus stack for NetBSD.

Now NetBSD-current contains IEEE 1394 isochronous aquisition driver. NetBSD-current after 20021204 doesn't required IEEE 1394 iso patch. To enable IEEE 1394 isochronous driver, kernel configuration file must contain fwiso and fwohci definition, like below:

	fwohci* at pci? dev ? function ?
	# fwohci* at cardbus? dev ? function ? # for CardBus
	pseudo-device fwiso	4

then recompile kernel.

To use IEEE 1394 isochronous from userland, device nodes must be prepared. For i386, type like this:

	mknod fwiso0 c 95 0
	mknod fwiso1 c 95 1
	mknod fwiso2 c 95 2
	mknod fwiso3 c 95 3

	mknod fwdv0 c 95 512
	mknod fwdv1 c 95 513
	mknod fwdv2 c 95 514
	mknod fwdv3 c 95 515

For macppc, type like this:

	mknod fwiso0 c 67 0
	mknod fwiso1 c 67 1
	mknod fwiso2 c 67 2
	mknod fwiso3 c 67 3

	mknod fwdv0 c 67 512
	mknod fwdv1 c 67 513
	mknod fwdv2 c 67 514
	mknod fwdv3 c 67 515

5 Play it

Connect a DV deck (or DV camcoder) with i.LINK connector. You can get DV data with this command.

	cat /dev/fwdv0 > file

You can see this data with playdv in libdv-0.6. You can find libdv-0.6 at sourceforge libdv-0.98 requires some patches. Playdv in libdv package will play dv data. You can see the number of dropped DV frames using `vmstat -e'.

6 develop some program with it

/dev/fwiso? support open, close, read and ioctl systemcalls. To install a include file for fwiso, go into sys/dev/ieee1394 directory and copy fwiso_ioctl.h in /usr/include/dev/ieee1394/.

	mkdir /usr/include/dev/ieee1394
	cp -p fwiso_ioctl.h /usr/include/dev/ieee1394/

You can get and set the mode of fwiso, the iso channel for fwiso, the interface device for fwiso using ioctl. Three tiny sample programs, fwisochmod, fwisoviewmod and fwisoanalysis, are delivered with driver.

Old patches IEEE 1394 isochronous driver kit (09Oct02) for NetBSD-1.6I/i386 and possibly NetBSD-1.6I/macppc. IEEE 1394 isochronous driver kit (14May02) for NetBSD-1.5ZC/i386 and possibly NetBSD-1.5ZC/macppc. IEEE 1394 isochronous driver kit (02Oct01) for older current

CardBus2 for NetBSD (Experimental, 19Oct00)

An improved CardBus stack for NetBSD. Power management and card insertion and removal handling is improved. You can insert or remove CardBus card (not 16-bit card) during suspend. CardBus bridge will go into D3hot mode during suspend if possible. How do you feel?
