 Posted: Thu Aug 08, 2002 4:28 pm Post subject: PCMCIA not loading nor unloading the modules! |
 |
|
1st: everything is working, I get the modules loaded by hands...
2nd: my pcmcia is actually a pcmcia-pci bridge, so this is not so laptop
the problem is that when /etc/init.d/pcmcia , no modules get loaded and starting of pcmcia failes
also, after I load the modules by hands, start the pcmcia and stop it, it doesn't unload the modules 
here is how my /etc/conf.d/pcmcia looks like:
| Code: | # more /etc/conf.d/pcmcia
# Should be either i82365 or tcic
PCMCIA=yes
PCIC=i82365
# Put socket driver timing parameters here
PCIC_OPTS="fast_pci=1 irq_mode=1"
# Put pcmcia_core options here
CORE_OPTS=
# Put cardmgr options here
CARDMGR_OPTS=
# To set the PCMCIA scheme at startup...
SCHEME=
|
as I said, it's all fixed now, my pcmcia works, but it was really a pain in my a*s before I got it worked out. I had to append some options to PCIC_OPTS and it didn't work, cause pcmcia startup script didn't seem to look the conf.d/pcmcia file 
is there any fix to this? how to get modules loaded when pcmcia is start up?
...and sorry my bad english

Did you add the lines | Code: | depend() {
need pcmcia
} |
to your /etc/conf.d/pcmcia file as mentioned in the Installation Guide? I didn't see it there, but I thought I would ask.

The Installation guide tells you to add need pcmcia to a net.ethx -file.
I'm using my wlan-card through pcmcia, but the problem is that it's PCMCIA which gets loaded first, and after it initialized my wlan-card with cardmgr -f, it attempts to run /etc/init.d/net.wlan0...
I didn't even have that file (net.wlan0), and just made a copy of my net.eth0.
There are the following lines on the top of my net.wlan0:
| Code: |
#for pcmcia users. note that pcmcia must be added to the same
#runlevel as the net.* script that needs it.
depend() {
use pcmcia
}
|
I dont think changing this to need pcmcia would help either, cause it's pcmcia that gets loaded before net.wlan0 in the 1st place
I also added this line into /etc/conf.d/net:
...so that the net.wlan0 -script actually works.
Now, because /etc/init.d/pcmcia tries to execute my /etc/init.d/net.wlan0, it's really pointless to rc-update add net.wlan0 default
This whole d*mn pcmcia-setup really bothers me. Why not to let pcmcia just use it's own /etc/pcmcia/networks.opts to set up network connections?
On the other hand, it would be nice, if I could just add my net.wlan0 to the default runlevel, and, when executed, it would use/need pcmcia, and that one would load the appropriate modules.
P.S. I actually haven't yet tried the last way

Sorry for the confusion. I was trying to ask if you had added it to your net.whatever file in /etc/init.d/ and got messed up. 
I would try that last way. I think I see your reasoning, but I don't know why your pcmcia file would try and start /etc/init.d/net.wlan0. I would think that it should be the other way around, especially if /etc/init.d/net.wlan0 depends on having pcmcia. Maybe if you add it to the default runlevel this will happen and all will be right with the world?

Still I need to load the modules by hand or /etc/init.d/net.wlan0 would just fail with a bunch of errors

Do you have an entry in /etc/modules.d/aliases for wlan0?

No I don't, cause I think it's pcmcia's job to probe for the card and load the apropriate modules (which it does...)

I saw this line: | Quote: | | Aug 14 19:48:49 cinderella modprobe: modprobe: Can't locate module wlan0 |
...and I thought that might be the problem. Which modules do you have to load by hand?

It looks like I didnt explain everything clearly 
Here is what I load by hands (the pcmcia-modules)

wlan-card's modules get loaded by pcmcia:
| Code: |
Aug 14 19:48:49 cinderella cardmgr[15620]: executing: 'modprobe prism2_cs'
Aug 14 19:48:49 cinderella kernel: init_module: prism2_cs.o: 0.1.15-pre1 Loaded
|
prism2_cs is the module for my wlan card. It's from the linux-wlan package by AbsoluteValue Systems (www.linux-wlan.org)

How about if you added these to /etc/modules.autoload, or is this not what you want either? It still wouldn't unload them, I guess, but it might make your life a little easier.

Cool - the only time I did any kernel hacking that actually got used by anybody. I doubt it's still listed, because it's ancient history now, but I went to a presentation Mark Matthews did at the first LinuxWorld in San Francisco, was instantly hooked on the idea, ordered two ZoomAir cards, picked up a 486 laptop from a company that was throwing them away for about US $100, turned it into a wireless/wired bridge, and then discovered that it didn't work on my Thinkpad and didn't work with kernel 2.2 (only supported 2.0 at that time). So I was sufficiently motivated to learn how Linux device drivers work and I fixed it and sent him patches, and was gratified to see my name in a driver changelog.

Actually that's what I did, since I couldn't come up with any better solution.
Anyway my original question was that it (pcmcia) doesn't load the modules when starting the init-script, doesn't load modules as it does in other distros. The problem with loading some modules by hand (or using /etcmodules.autoload), is that you'll also need to specify any extra options into /etc/modules.conf. Those options belong (in pcmcia's case) into /etc/conf.d/pcmcia, which doesn't get loaded (at least here).
The reason why pcmcia's startup-config-file (/etc/conf.d/pcmcia) should get read by the pcmcia, is because when you read the PCMCIA-HOWTO or some other documents, they're all telling you to modify your distro's specific startup-config-file

Nice, the driver is working great here. thanks for your job guys

Perhaps a very basic and pointless question, but are you using the kernel's pcmcia code or pcmcia-cs? A forum search for "pcmcia and modules" turned up 70 threads, among which were this, this, this, and this, in case any of these are of some use to you.

I'm using the pcmcia-cs package, together with the linux-wlan package for my card. All the kernel stuff is naturally disabled, as I've been told it's the best to do in many thousand docs
Still, in all those threads people are talking about modprobe i82365..., putting the pcmcia modules into /etc/modules.autoload.
But I think (and I really believe) that pcmcia should be able to load the modules by itself because I've seen this happening before.
I've used LFS and the modules got loaded by the init.d -script and the options I've put as PCIC_OPTS into /etc/sysconfig/pcmcia were applied to the i82365 module. LFS doesnt really have any own mechanisms, which would help pcmcia with the modules. I just did the make config, make all, make install when installing pcmcia-cs, and used the init.d -scripts that came with the pcmcia-cs package...
NOT that I couldn't live without that now in Gentoo, since everything really is working. I'm just wondering if anyone else is/was having problems with this issue, because they need some extra options for their pcmcia-bridges.

Well, then you might want to consider filing a bug report against pcmcia-cs on bugs.gentoo.org. I think that if you reference this thread, you will certainly be able to demonstrate that you have researched the issue thoroughly.
