Solved make buildkernel error for SCSI_DELAY=5000

[Naval]

Good Day!

Sorry, if the post is not in specialized category.

Today was trying to built custom kernel

Having thoroughly read handbook section 8.4. I create own kernel config.

After starting make buildkernel KERNCONF=[I]MYKERNEL[/I] I do receive error for string in own config file.

String was attributed to the

nooptions    SCSI_DELAY=5000     # Delay (in ms) before probing SCSI

.

Having commented it out, I resumed built and it went well.

Question.
I do not have any SCSI devices and I commented all the SCSI and RAID related sections including options related to SCSI and RAID, so why was the kernel built was with error?

What dependencies have option

SCSI_DELAY=5000

to rest non-SCSI devices?

Parts of the system handle all storage as SCSI. Confusing maybe, but nothing to worry. Just keep the option and think it as DISK_DELAY

My guess would be that either the option does not exist because the code that uses it has been removed from the custom kernel, or nooptions does not like it when the option that is being removed is also being assigned a value. Unfortunately, the actual error message was not shown.

Thanks for replies.

Actual error message not saved.

But no building stated at all. Was something like "config error line xx".

Thanks. Today 1st time built my kernel.

Regarding building the kernel and so on you might also want to read https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/updating-upgrading.html
and http://www.wonkity.com/~wblock/docs/html/buildworld.html. script(1) as mentioned in https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html is very useful to record huge sessions for later analysis. I use it quite often, not only for building world or kernel.

I wish you happy and successful compiling .

"config error line xx" _does_ come from config(8), it doesn't like the extra "=NNN"

Juha,

Just tested, indeed all went well with depreciated reminder of '=5000' of

nooptions    SCSI_DELAY=5000

.

Thanks. I will mark thread as solved.

Mr Block had the hawk eyes.

I'm confused, though. If you have nodeviced all SCSI away, why do you care about the cpp variable ? If some generic cam/disk/storage code uses it in a generic way, have you checked which direction the default value takes ? Will it be 1000 or 10'000 now ?

Juha,

I was care only for 'ideal' built - at least as seams for me .

From mine beginner side, it seems strange that I putting option related to SCSI to 'nooption', but make does not begins due to error.

It was assumed by me that if some devices placed in MYKERNCONF with 'nodevice' option, then their options should be set to 'nooption' as well.

 

[Juha Nurmela]

No worries, I'm also assuming on thin ice.

For the record, default SCSI_DELAY is 2000 msec. I still don't know if it affects all storage somehow.
