There are two ways to utilize 1394 pccards on Linux - with the kernel's own CardBus driver or with pcmcia-cs. See pcmcia-cs' README-2.4 for explanation of differences. Both or only one of the two ways may work for you. Both work for me. I can test only ohci1394, not pcilynx.
This is the way supported by the IEEE 1394 linux driver maintainers.
To have CardBus support in the kernel, build it with
CONFIG_PCMCIA=Y ("CardBus support") and with
the ohci1394 and/or pcilynx driver. The kernel module responsible for
1394 pccards is called ohci1394.o or pcilynx.o and can be loaded
manually (use modprobe) or by the
Note that suspend + resume do not work yet, and card ejection is unstable. I recommend to unload all IEEE 1394 kernel modules before ejecting the pccard or before putting the computer into power saving mode.
You can run pcmcia-cs' cardmgr in parallel to a CardBus enabled kernel for traditional configuration of 16bit PCMCIA cards using /etc/pcmcia scripts.
If you experience problems regarding resource management, try kernel 2.4.20 --- or pcmcia-cs:
This way is not supported by the IEEE 1394 linux driver maintainers. But you may be forced to this option if the 2.4/ 2.5 kernel does not work properly with your CardBus bridge. Let standalone pcmcia-cs drivers operate the CardBus then. You need
Build a kernel without CardBus support:
but with IEEE 1394 support. Install kernel and modules. Change to the
directory containing pcmcia-cs sources and apply the patch:
bzcat /path/to/patchfile | patch -p0
Read and understand PCMCIA-HOWTO, build and install pcmcia-cs:
make config make all make install
The kernel module associated to 1394 pccards is then called ohci1394_cb.o or pcilynx_cb.o and should be loaded by the pcmcia-cs cardmgr.
Be warned that the system locks up hard when a 1394 pccard served by pcmcia-cs is ejected (at least my system does so). Avoid this by unloading IEEE 1394 high-level drivers such as sbp2 and then running cardctl eject every time before ejecting the pccard or before putting the computer into power saving mode.
