a. save the existing kernel file and its kernel function set directory as
/stand/vmunix.prev and /stand /dlkm.vmunix.prev, respectively
b. move the newly generated kernel file and its kernel function set
directory to their default locations, /stand/vmunix and
/stand/dlkm, respectively
After the system reboots, your DLKM module will be available as
statically configured in the new running kernel.
DLKM Glossary
Auto load A capability made possible via the DLKM feature. Auto
loading occurs when the kernel detects a particular
loadable module is required to accomplish some task,
but the module is not currently loaded. The kernel
automatically loads the module. During an auto load,
the kernel also loads any modules that the module
being loaded depends upon, just as it does during a
demand load.
CDIO Context-Dependent Input/Output. A feature of the
HP-UX I/O subsystem that provides a consistent
interface for I/O busses and device drivers.
DLKM Dynamically Loadable Kernel Module. A feature
available in HP-UX 11.0 that supports dynamic loading
and unloading of kernel modules, to avoid wasting
kernel memory by keeping modules in core when they
are not in use.
DMA Direct Memory Access. High-speed transfer of large
quantities of data between the computer memory and a
peripheral device without involving the computer
central-processing unit. The central-processing unit is
halted during the data transfer and resumes operation
when all of the information has been transmitted.
Kernel module A section of code responsible for supporting a specific
capability or feature. Normally, such code is
maintained in individual object files and/or archives,
enabling modules to be conditionally included or
excluded from the kernel, depending on whether or not
the features they support are desired.
