Based on some examples in /usr/share/lkm, I have started adding
|
|
|
|
|
loadable modules for some portions of NetBSD I don't think should
|
|
|
|
|
require a kernel rebuild to install.
|
|
|
|
|
|
|
|
|
|
So far, I have added the following:
|
|
|
|
|
|
|
|
|
|
cd9660
|
|
|
|
|
fdesc
|
|
|
|
|
kernfs (slightly different than in /usr/share/lkm)
|
|
|
|
|
msdosfs
|
|
|
|
|
mfs
|
|
|
|
|
nullfs
|
|
|
|
|
portal
|
|
|
|
|
procfs
|
|
|
|
|
umapfs
|
|
|
|
|
union
|
|
|
|
|
|
|
|
|
|
Building and Testing
|
|
|
|
|
--------------------
|
|
|
|
|
|
|
|
|
|
mkdir /usr/lkm (if it's not there)
|
|
|
|
|
make depend && make && make install
|
|
|
|
|
|
|
|
|
|
Then, to install cd9660, for example, type:
|
|
|
|
|
modload -v -e cd9660_lkmentry -o /var/run/lkm.cd9660 /usr/lkm/cd9660.o
|
|
|
|
|
(or "make load" in the correct directory)
|
|
|
|
|
|
|
|
|
|
To remove it from memory, type:
|
|
|
|
|
modunload -n cd9660
|
|
|
|
|
(or "make unload" in the correct directory)
|
|
|
|
|
|

Notes
|
|
|
|
|
-----
|
|
|
|
|
|
|
|
|
|
Currently there is no symbol table management so the in-kernel debugger will
|
1999-08-25 04:59:08 +04:00
|
|
|
lose.
|

|
|
|
|
|
|
|
|
The LKM interface will (hopefully) be changing into something more usable.
|
|
|
|
|
If you use these files as a reference, you might have to change your
|
|
|
|
|
code if you want to use the new interface. I expect the old one to be
|
|
|
|
|
supported if it is possible to do so.

COMPAT modules
|
|
|
|
|
--------------
|
|
|
|
|
|
|
|
|
|
The FreeBSD module DOES load, but it will not work without other kernel
|
|
|
|
|
modifications.
|
|
|
|
|
|
|
|
|
|
The Linux module compiles, and also requires other kernel modifications
|
|
|
|
|
to run. It has not been tested.
|
|
|
|
|
|
|
|
|
|
VFS modules
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
These are somewhat tested. Since this whole system is still under
|
|
|
|
|
development use these at your own risk.
