SCC Card Driver

SCC Card Driver

[Ray Wells]

I grabbed kernel 2.6.24.4 yesterday and there is no option in the ax25 
configuration for the SCC driver.

Can anyone advise if this is an oversight?

Oops. That should read 2.6.25.4

Did you enable ISA support?

config SCC
        tristate "Z8530 SCC driver"
        depends on ISA && AX25 && ISA_DMA_API

You raise a good point and I didn't check. I did notice that all ax25 
kernel stuff is no longer enabled as modules by default.

I suspect there has been a change between 2.6.25.1 and 2.6.25.4 because 
in 2.6.25.1 (which I'm compiling now) the ax25 stuff, including SCC, is 
enabled as modules by default.

Perhaps I was to used to what used to be!! Slap on wrist.

Thank you for your suggestion.

Ray,
    What distro are we talking about?  mkiss and ax25 modules are 
present on Fedora 9 with the 2.6.25.3 kernel.  Including them or not is 
normally a distro specific thing.

Mike,

I'm compiling on Debian 4.0 but as you say, it shouldn't be relevant. 
The kernel source came from kernel.org.

Just to be sure I wasn't fooling myself, with both 2.6.25.1 and 2.6.25.4 
I deleted the unzipped source and unzipped again. For each source I ran 
make menuconfig. The ax25 options were not selected by default in 
2.6.25.4 but they were in 2.6.25.1.

I haven't been able to go back into 2.6.25.4 to see if ISA was selected 
re the SCC problem but I'll do that probably today.

The raw kernel from kernel.org has bare minimum enabled.  You need to 
get a "config" file from your running system to enable all that the 
distro does by default.  I have also found that there are usually a lot 
of other drivers that need to be enabled just to make it run at all.

Mike,

I normally use my old config file but because I'm jumping quite a few 
kernel releases I decided to start from scratch.

I did some more investigating this morning and this is what I found.....
1. The SCC driver not appearing in 2.6.25.4 is due to ISA not being 
selected - my oversight.
2. In kernel 2.6.25.1 ISA is preslected, and all ax25 is preselected as 
modules
3. In kernel 2.6.25.4 ISA is not preslected and all ax25 is not preselected

Looks like there has been some serious culling of unessential drivers 
between 2.6.25.1 and 2.6.25.4. Takes me back to 2.0.x kernels.

Ray,

Are you aware of the kernel makefile target "oldconfig"?

Put your old config file in the proper directory for the kernel build and
do a make oldconfig and you will get prompted for the new stuff without changing 
already selected kernel options.
