Dear Scott,
I am glad to see you. I am working based on your RAIDFrame 2000-06 patc=
h. =20
I know you are so busy. So I am trying to transfer them myself. :)
About RAIDFrame, I have talk about some problems with Oster.
Let me talk about some work about RAIDFrame.
This is the first I hack the kernel. so I have a lot of problem about Fr=
eeBSD kernel.:(
First, I replace the simplelock with mutex, modify many proc parameter t=
o thread and
modify some buf structure to bio structure.
I think I must compile successfully firstly.:)
Now, I try to trace those command('raidctl').
When I excute the 'raidctl -C configfile'. the system is panic. I think =
the ioctl thread parameter
should be hold by rf_Configure, right? But the FreeBSD4.x version did not=
hold the ioctl proc paramter.
I know little about Gaint. I only know the Gaint is the global mtx var, b=
ut I do not know how to use it.
Could you give me some Gaint usage knowledge or relative articles ?
Hmm... I really want to learn the FreeBSD kernel by this experience. =20
Best Regards
Ouyang Kai

Have you taken the proper steps to handle Giant in the RAIDframe
kernel thread?
That said, I'm getting close to having -current RAIDframe patches
available. It's starting to work well on my system, and I'm squashing
Witness warnings as they come up.
