comment "An alternative FireWire stack is available with EXPERIMENTAL=y"
depends on EXPERIMENTAL=n
NOTE:
You should only build ONE of the stacks, unless you REALLY know what
- you are doing. If you install both, you should configure them only as
- modules rather than link them statically, and you should blacklist one
- of the concurrent low-level drivers in /etc/modprobe.conf. Add either
-
- blacklist firewire-ohci
- or
- blacklist ohci1394
-
- there depending on which driver you DON'T want to have auto-loaded.
- You can optionally do the same with the other IEEE 1394/ FireWire
- drivers.
-
- If you have an old modprobe which doesn't implement the blacklist
- directive, use either
-
- install firewire-ohci /bin/true
- or
- install ohci1394 /bin/true
-
- and so on, depending on which modules you DON't want to have
- auto-loaded.
+ you are doing.
config FIREWIRE_OHCI
tristate "Support for OHCI FireWire host controllers"
NOTE:
- If you also build ohci1394 of the classic stack, blacklist either
- ohci1394 or firewire-ohci to let hotplug load only the desired driver.
+ You should only build ohci1394 or firewire-ohci, but not both.
+ If you nevertheless want to install both, you should configure them
+ only as modules and blacklist the driver(s) which you don't want to
+ have auto-loaded. Add either
+
+ blacklist firewire-ohci
+ or
+ blacklist ohci1394
+ blacklist video1394
+ blacklist dv1394
+
+ to /etc/modprobe.conf or /etc/modprobe.d/* and update modprobe.conf
+ depending on your distribution. The latter two modules should be
+ blacklisted together with ohci1394 because they depend on ohci1394.
+
+ If you have an old modprobe which doesn't implement the blacklist
+ directive, use "install modulename /bin/true" for the modules to be
+ blacklisted.
config FIREWIRE_SBP2
tristate "Support for storage devices (SBP-2 protocol driver)"
You should also enable support for disks, CD-ROMs, etc. in the SCSI
configuration section.

- NOTE:
