Modules and startup speed

nukey · 06-14-2005, 03:39 PM

I consider my linux knowledge nearing avarage, I've got a http/https/mail/sql/webmail etc etc server running so i know some basic stuff

Now for the desktop (slack current on P4 3Ghz 512MB). It's running pretty wel but some things bother me.

The first thing is the hardware-detection during boot-up, it takes forever. Offcourse i googled and LQ-ed and i understand i can disable it and that i should load the modules i need at startup, but i don't know exactly where to start. I guess i sould do an lsmod right now and load all that modules at startup, but that's a whole bunch:

Code:

Should i modprobe at startup for all these modules ? or what would you suggest. ?

The other for which i've also done some reading is the "updating shared library links". I read i could make this run after boot by putting a delay in the command. Is that wise, is updating the shared library links nessecary at every startup ?

lspci gives this output (may be needed to answer some of my questions

dmesg gives some strange agpgart notification (which i searched for but still have to fix) but it also give is whole lot of PCI Hotplug thingies, anybody know what's wrong ? Or is nothing really wrong ?
This is the output of dmesg

Any help is appreciated, just point me in to the right direction and i'll figure the rest out for myself

You could start by disabling rc.hotplug. That is usually where the slowdown at startup comes, and it's usually useless if you aren't changing your hardware around.

Adding modprobe for the hardware is quicker. It's also quicker to compile the hardware directly into the kernel. The latter option, however, comes at the expense of having more things that can go wrong within the kernel. More accurately, if a driver does crash, it'll bring down the system.

That said, I usually compile directly into the kernel, and I've never had a problem. The only thing that's a module on any of my systems is MadWiFi, for the Atheros-based wlan card in my laptop. For older hardware, you're generally safe. Your system appears to be a VIA 82C-based system. So's my laptop, so you should be fairly safe compiling in.

Some thoughts on tweaking your setup:

1) You get the error message:

Code:

agpgart: Unsupported Via chipset (device id: 0258), you might want to try agp_try_unsupported=1
agpgart: no supported devices found.

You can fix that by adding

Code:

add options agpgart agp_try_unsupported=1

To /etc/modules.conf (2.4 kernel) or /etc/modprobe.conf (2.6 kernel)

2) Speed trick for booting. Uncomment:

Code:

compact        # faster, but won't work on all systems.

You'll get a warning that it may break your system. I'm crazy enough that I took the gamble. No breakage, faster boot. YMMV.

3) Compile a new 2.6 series kernel.

Add pre-emtable option.

Compile for your processor.

You seem to have a 3G P4 processor. I would guess that it has hyperthreading. Enable SMP and hyperthreading.

Get rid of stuff you don't need.

4) Disable hotplug if you want. You seem to use USB devices. Hotplug will load the modules for them "on-the-fly". I like that better than speeding up the boot time by ditching the feature.

5) You can eliminate ldconfig if you like. Just remember to run it whenever you install new software.

6)

Code:

kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2

Enable scsi emulation in /etc/lilo.conf if you are wanting to use it. Otherwise, edit /etc/rc.d/rc.modules to remove this error.

7)

Believe the pcihotuplug is for hot swapping. Might be wrong, but if so, you don't need it. Take that out when you recompile.

8)

Gonna take a break for now.

Thank you both, seems like i've got a little work to do this evening

Does the 2.4 kernel also have support for SMP by the way ?

Have you also got any more tips on the "hardware detection" , i mean if want to load
modules instead of using the hardware-detection should i modprobe for everything
that gets listed with lsmod ?

I did a few 2.4 kernel recompiles, most of them went fine.
For a 2.6 kernel, is it wise to install the 2.6.x kernel first (that comes with the slackware)
and then lateron make menuconfig while taking the slackware's config file to start from ?

killerbob · 06-15-2005, 07:30 AM

the 2.4 kernel *can* have support for SMP. I don't know whether the install kernel does, but probably not. It increases the kernel size for something that, while it improves performance on SMP systems, actually reduces performance on most other machines.

Ok, thanks

But can anyone put me in the right direction on how the handle the "hardware detection"/modprobe issue, that one in particular is bothering me and i don't exactly know where to begin.

nukey · 06-15-2005, 05:16 PM

Running a 2.6 kernel right know, hardware detection allready seames to take less time that before.

I'm getting a Disabling IRQ #10 after the hardware detection though.

I'm recompiling again right now, finaly found the SMP thingie in the kernel config, damn, annoying when your looking for "SMP" but i first didn't notice the whole words were standing there, not the abbreviation (or however you say or type that :P )

No problems with the agpgart with this kernel by the way.

But the hardware detection is still taking most of the time at startup, i tried to start every module (that's loaded when hardware-detection is on) by other means, they all get loaded, but then my networkcard isn't getting an ip-adress (haven't tested anything else, since i go crazy when i don't have a network connection

). I really think i'm missing something here.

When did you tried to start every module you need? You shoud do that in /etc/rc.d/rc.modules that's executed before the network is initilizated.

Yap, that was the problem, thank you

nukey · 06-15-2005, 05:50 PM

Ok, the recompile also worked, since "cat /proc/cpuinfo" gives me 2 procs now

Still need a little extra kernel tweaking but right now i'm pretty happy with the boot-time and the system-response.

Thank you all for answering my questions
