Subject: rt2x00 - wireless compat - can not load compiled rt61pci
Date: Sun, 17 May 2009 12:50:43 +0200	[thread overview]
Message-ID: <4A0FEC03.9090803@centrum.cz> (raw)

Hello,

I use latest Mandriva distribution 2009.1 with kernel 
2.6.29.1-desktop-4mnb. I have rt2561 wifi card in my PC. I would like to 
switch my wifi card to AP or Ad-hoc mode. My distribution's rt61pci 
module doesn't support these modes. So I have downloaded 
compat-wireless-2.6.30-rc4.tar.bz2 
<http://www.orbit-lab.org/kernel/compat-wireless-2.6-stable/v2.6.30/compat-wireless-2.6.30-rc4.tar.bz2>.

I ran:
make
make install
make unload

Everything fine. But then "modprobe rt61pci" loaded my distribution's 
rt61pci module and not the compiled one. Distribution's one is in folder:

[root@trencancan compat-wireless-2.6.30-rc4]# ls -la 
/lib/modules/2.6.29.1-desktop-4mnb/kernel/drivers/net/wireless/rt2x00/rt61pci.ko.gz
-rw-r--r-- 1 root root 11279 2009-04-21 01:13 
/lib/modules/2.6.29.1-desktop-4mnb/kernel/drivers/net/wireless/rt2x00/rt61pci.ko.gz

Compiled one is in folder:
[root@trencancan compat-wireless-2.6.30-rc4]# ls -la 
/lib/modules/2.6.29.1-desktop-4mnb/updates/drivers/net/wireless/rt2x00/rt61pci.ko.gz
-rw-r--r-- 1 root root 123843 2009-05-16 23:21 
/lib/modules/2.6.29.1-desktop-4mnb/updates/drivers/net/wireless/rt2x00/rt61pci.ko.gz


But after I type "modprobe rt61pci", then:
[root@trencancan compat-wireless-2.6.30-rc4]# modinfo rt61pci

So you can see that Distribution's module (in kernel folder) was loaded. 
I think root cause of problem is that run of command: "depmod -ae" finds 
first rt61pci in kernel's folder and then next instance in updates 
folder is not considered. If I look at output of depmod command:

[root@trencancan compat-wireless-2.6.30-rc4]# grep -i rt61pci 
/lib/modules/2.6.29.1-desktop-4mnb/modules.dep
kernel/drivers/net/wireless/rt2x00/rt61pci.ko.gz: 
kernel/lib/crc-itu-t.ko.gz 
kernel/drivers/net/wireless/rt2x00/rt2x00pci.ko.gz 
kernel/drivers/net/wireless/rt2x00/rt2x00lib.ko.gz 
kernel/net/rfkill/rfkill.ko.gz kernel/drivers/leds/led-class.ko.gz 
kernel/net/mac80211/mac80211.ko.gz kernel/net/wireless/cfg80211.ko.gz 
kernel/drivers/misc/eeprom/eeprom_93cx6.ko.gz

So you may see that rt61pci in 
/lib/modules/2.6.29.1-desktop-4mnb/updates/drivers/net/wireless/rt2x00/ 
folder is not considered.

Please, how can I workaround this? Or what do I wrong? One solution can 
be to install all compat-wireless modules into kernel folder instead of 
updates folder. But then distribution's ones will be overwritten and 
un-installation will be impossible.

Thanks.
