dummy_cb - CardBus dummy device driver
insmod dummy_cb.o [pc_debug=n]
The dummy_cb module is a sort of "point enabler" for CardBus cards.
When it is bound to a card, it configures that card, but otherwise does
not do anything. It may be useful for cards that have Hot Plug PCI
kernel drivers, but do not have CardBus client drivers in the pcmcia-cs
package. Hot Plug PCI drivers expect the kernel to handle CardBus card
configuration; instead, drivers in the pcmcia-cs package rely on the
cb_enabler module to do that.
To use dummy_cb, edit /etc/pcmcia/config.opts and add one or more card
card "Western Digital 1394 Adapter"
pci 0x1033, 0x00cd
This will override any driver bindings in the main config file. After
restarting cardmgr, then, insertion of these cards should load
dummy_cb. After that, the Hot Plug PCI driver can be loaded.
Before ejecting a card using dummy_cb, it is important to manually
unload the corresponding Hot Plug PCI driver. Since cardmgr cannot
notify this sort of driver about removal events, bad things can happen
if the Hot Plug PCI driver is not unloaded first. Yes this is rather
fragile. Ideally, people will use Hot Plug PCI drivers with the kernel
PCMCIA subsystem, but dummy_cb is meant as a quick fix for situations
where that is not possible.
Selects the PCMCIA debugging level. This parameter is only
available if the module is compiled with debugging enabled. A
non-zero value enables debugging.
