mthread(ADM)
mthread --
show multithreaded drivers and line disciplines
Syntax
/etc/mthread [ -bclms ]
Description
mthread displays multithreaded device drivers and
line disciplines that are currently
configured and running in the UNIX system kernel.
mthread accepts the following options:
-b-
Display multithreaded block device drivers.
-c-
Display multithreaded character device drivers.
-l-
Display multithreaded line disciplines.
-m-
Display multithreaded STREAMS modules.
-s-
Display multithreaded SCSI adapter drivers.
Exit values
mthread exits with 0 upon successful completion;
it exits with 1 on error.
Diagnostics
mthread displays the following messages on error:
mthread: cannot open /dev/at1
-
The control device node for the ci driver is missing. Run
idmknod(ADM)
to recreate it.
mthread: cannot determine multithreaded drivers
-
The currently booted kernel does not support mthread.
Relink and reboot with the ci
kernel module configured into the Link Kit.
Limitations
mthread is intended for use with multiprocessor systems
only. It requires the ci driver to be
configured into the kernel, and will not work with older versions
of this driver.
Multithreaded drivers will not appear in the output of
mthread until they have been opened and they have
registered themselves as multithreaded.
