 Posted: Sun Sep 19, 2004 8:32 pm Post subject: how to compile an external module into the kernel |
 |
|
I have a GigaRAID raid cotroller on board, and I want to compile the module available from http://www.iteusa.com/ in to the kernel.
The steps I have tried as of now. I copy the files iteraid.c and iteraid.h in to the kernel tree's subfolder drivers/scsi. Then I change directory to the kernel top-level directory, and execute:
| Code: |
patch -p1 < ../linux-2.6.7-gentoo-r8a.patch
|
linux-2.6.7-gentoo-r8a.patch contents:

I then move on to configuring the kernel, but the configuration menu only gives me two options. Not compiling ITE IT8212 support, or compiling ITE IT8212 support as a module. I want ITE IT8212 support built in the kernel. So I can boot directly off the ide raid. Can I do this with ite's code, and how can I do this.
Side note, any suggested changes to Title "howto compile module in the kernel" that could make it easier to find though a search.

Horatio,
Your patch says:-
| Code: | +config SCSI_ITE_RAID
+ tristate "ITE IT8212 support"
+ depends on SCSI && PCI && EXPERIMENTAL |
The tristate means the options Y/M/N are available.
It depends on SCSI and PCI however, so if either of those are modules, you will not be able to say Y here.
Check the top level setting for SCSI it must be Y before you get to see the option you want.

I would change it to "how to compile an external module into the kernel".
The iteraid module will only be available as a builtin if you enabled that for everything it depends on as well.
That specifically means scsi support.
I.e. if scsi support = M, then anything scsi has to be M as well.

Gosh, I'm new at kernel hacking. Those suggestions did the trick. I've yet to really test this driver. I've only use fdisk to test if I could see the partions, drive size, etc.
Anyway, the line of the patch that reads:
| Code: |
+ depends on SCSI && PCI && EXPERIMENTAL
|
should be changed to:
| Code: |
+ depends on SCSI && BLK_DEV_SD && PCI && EXPERIMENTAL
|
Cheers. |
