Tpowa's "Simple Hardware Detection"

ozar · 2005-11-10 23:05:26

Info posted by Judd, here: http://www.archlinux.org/blog/2005/11/1 … detection/

Any of the rest of you playing around with this? I decided to give it a go and it seems to work pretty well, at least thus far. It reminds me of hwd/lshwd but no entry is needed in rc.conf and it does allow for faster boot times than those you get when using hotplug.

Anyway, it looks like it might have potential.

dtw · 2005-11-11 10:30:22

well, dude, hwd and lshwd could be run straight from rc.sysinit too if you wanted

tpowa · 2005-11-11 12:41:12

you all miss one point, this detection runs with basic linux utils and is really precise in loading modules.

Er...no. I didn't miss that at all. I was just saying that running from rc.sysinit was not restricted to anything - few people realize how easy it is to customize the initscripts

ozar · 2005-11-11 15:04:03

Yeah, I'd think you could run just about anything from rc.sysinit with the correct coding placed in it.

I am using custom kernel.
Kernel: 2.6.11.5-w4l-ARCH

[root@localhost /]# /sbin/hwdetect.sh -load-modules

tpowa · 2005-11-11 17:07:46

rasat for me sounds this like you have everything in the kernel , dont you?
EDIT: Ah thanks i changed the script to look in /sys/devices only

rasat · 2005-11-11 17:28:08

Kernel: 2.6.13-ARCH
No error messages. But also no modules were loaded same as with my custom kernel.

For the test, I tagged the MODULE line in my rc.conf
# MODULES=(!usbserial !ide-scsi uhci_hcd 8139too lp parport_pc snd_intel8x0)

tpowa · 2005-11-11 17:33:07

rasat try to change the line with find /sys
to find /sys/devices, that should fix your trouble.

Nop, no modules are loaded.

I suggest, you test it on a fresh Arch install with base packages only to make sure any type of module loader is not installed.

tpowa · 2005-11-11 17:51:52

rasat i mean to test you should try -show-modules

Notwithstanding that mouse entry in lshwd, I'd like to see evdev detected for my Synaptics touchpad - hotplug can do this, but lshwd and hwdetect can not.

tpowa · 2005-11-12 08:22:53

hm with evdev i'm not sure, hotplug tries to load a lot of modules, that's the reason for being slow, if evdev is not exported by /sys it cannot be autodetected.

And please remeber, this script shows you only modules that can be loaded, if the stuff is already in kernel it doesn't show you the modules.
the script has benn updated yesterday evening, so please try the new one.

Hi,

Can you add version to your script (please) so I can keep track of changes ;-)

running hwdetect -show-modules seems ok

Seems okay, however there are two issues:

1) 8139cp and 8139too are both detected but only 8139too should,
2) loading via-agp and running a 3D application (ie. tuxracer or glxgears) hangs my computer for good.

Mr Green · 2005-11-12 12:27:12

1) 8139cp and 8139too are both detected but only 8139too should,

Same here .....

tpowa · 2005-11-12 12:36:06

this 8139 is a very old bug, that comes from the kernel itself, it is not fixable.
they both have the same entries, but it doesn't hurt to load 8139cp and 8139too, because one of it fails.

tpowa · 2005-11-12 13:17:05

swiergot, confirmed the crash, but this only happens when you load tha agp driver when nvidia is already loaded, else it works.

swiergot · 2005-11-12 13:24:58

So, is via-agp not needed with nvidia loaded or is it a bug in either modules? Anyway, IMHO hwdetect must not let the crash happen.

tpowa · 2005-11-12 13:30:53

no i mean, if you use it with -load option on statup it will not happen the crash, because agp gets loaded before nvidia is loaded.

swiergot · 2005-11-12 13:36:34

And then loading nvidia will not crash?

tpowa · 2005-11-12 13:38:50

try it: load your agp module before! nvidia then it shouldn't crash
