[gentoo-user] where to find udev tarball
Hi, Recently saw that i have a udev-tarball enabled setup and think of disabling it. Wanna make a backup of the tarball before doing that, but can't find where it is located/saved. TIA. Rumen smime.p7s Description: S/MIME Cryptographic Signature

Thanks Zac. So this explains why if I set RC_DEVICE_TARBALL=no that
I don't use it.
My question is how do the devices get created if TARBALL=no? Is it
only the 50-udev.rules file that's responsible? I'm trying to debug
why none of my machines have the lirc/lirc0 devices like the Gentoo
Wiki's say they should.
Thanks,
Mark

The whole tarball thing is strongly against the ideas behind udev. udev reads information about your hardware from /sys (and listens for and creates nodes based on that. If you don't rely on the tarball stuff, it's perfectly safe to do: # rm -rf /dev/* # ls /dev # almost empty # udevstart # ls /dev # everything is back I'm trying to debug why none of my machines have the lirc/lirc0 devices like the Gentoo Wiki's say they should. You need to load the lirc module first. But there is always the possibility that the lirc module is not sysfs-aware, in which case it won't put anything in /sys, so udev won't know anything about it.

Hi Daniel. I've jsut been reading your primer on UDEV. Thanks. On 6/19/05, Daniel Drake [EMAIL PROTECTED] wrote: Mark Knecht wrote: My question is how do the devices get created if TARBALL=no? Is it only the 50-udev.rules file that's responsible? The whole tarball thing is strongly against the ideas behind udev. Yes, normally I've been using TARBALL=no and jsut letting the system create the devices. That has worked so far, but it's not working for this IR receiver that's part of lirc/mythtv. udev reads information about your hardware from /sys (and listens for and creates nodes based on that. If you don't rely on the tarball stuff, it's perfectly safe to do: # rm -rf /dev/* # ls /dev # almost empty # udevstart # ls /dev # everything is back Humm...almost everything. ;-) The /dev/lircd entry I had was not recreated. Maybe that's a sign of that stuff not being set up right? It was recreated after zapping and starting the lircd daemon again: myth12 ~ # /etc/init.d/lircd start * Starting lircd ... [ ok ] myth12 ~ # ls -al /dev/lirc* srw-rw-rw- 1 root root 0 Jun 19 15:21 /dev/lircd myth12 ~ # I'm trying to debug why none of my machines have the lirc/lirc0 devices like the Gentoo Wiki's say they should. You need to load the lirc module first. But there is always the possibility that the lirc module is not sysfs-aware, in which case it won't put anything in /sys, so udev won't know anything about it. Yes, the modules (I hope the right ones) are loaded: myth12 ~ # lsmod Module Size Used by fglrx 240380 0 agpgart28968 1 fglrx snd_usb_audio 63680 0 snd_usb_lib11520 1 snd_usb_audio snd_rawmidi20640 1 snd_usb_lib snd_atiixp 17120 0 snd_ac97_codec 75384 1 snd_atiixp lirc_i2c8836 0 i2c_core 18704 1 lirc_i2c lirc_dev 13156 1 lirc_i2c myth12 ~ # The device is visible in /proc/bus/usb/devices: T: Bus=03 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 2 Spd=1.5 MxCh= 0 D: Ver= 2.00 Cls=00(ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=0e9c ProdID= Rev= 1.00 S: Manufacturer=Streamzap, Inc.

It's pretty nice. cheers, Mark -- gentoo-user@gentoo.org mailing list

Daniel Daniel, I found it. The Gentoo Wiki for MythTV shows how to build in support for a remote that I don't use. They don't mention that this one line should be change, nor do they suggest where to get the info to know how to change it. Once I noticed a message while lirc was building that said something about looking at the ebuild source to see what remotes it supported it became clear I needed to change this one line in the instructions to choose my remote. This built a different driver which, when loaded, created all the /dev devices and I now have a working remote. Cheers, Mark -- gentoo-user@gentoo.org mailing list

Hi,
Thanks Zac.
Begun searching for it, stopped too early. Had done such a backup before
only that didn't record the location.
Rumen.
