how to build your own ubuntu rt-kernel?

[studio32]

Hi,

How can I build my own Ubuntu rt kernel?

*I don t know why I posted this thread not in system configuration...


After building a Ubuntu kernel, should I also build the Linux-Restricted-Modules?

should I do something with realtime-lsm? http://packages.ubuntu.com/hardy/realtime-lsm-source

[studio32]

I tried to build 24.4-rt , it went ok, but guess what? After booting no soundcard, wtf!

What could this be?

edit: where can I find the boot messages? how do I turn this on (to get a file somewhere?)

Just because I'm curious, why are you building your own kernel?

I used to do this all the time a few years ago, back when the kernel modules weren't quite a reliable as they are now and you usually had to build your own kernels if you wanted all your hardware to work. These days the modular kernels seem to pretty much just work so it seems like custom compiling a kernel isn't worth the effort. I haven't had to compile a kernel in quite a while.

Your reply doesn't solve my problem.... but I do this to learn... I want to be able to build my own rt kernel!

Someone which can help me with this?

edit: where can I find the boot messages? how do I turn this on (to get a file somewhere?)

in a terminal, type

Code: Select all

dmesg

or inspect stuff in /var/log
most system logs are in there (syslog, message, etc)
There's a file called boot. It will be empty if bootlog is not on. To turn this on, change the file /etc/default/bootlogd (replace option with yes) and reboot

about your kernel config, have you turned on ALSA and PCI card option for your card ?

in terminal, type

Code: Select all

sudo modinfo snd-ice1712

as I presume that's the driver you need (Delta card).
if the module does exists, then test it :

Code: Select all

# load the module
sudo modprobe snd-ice1712

# check if something shows up  
cat /proc/asound/cards

# start the h/w mixer
envy24control

Generic kernel works ok.

[thorgal]

have you configured the kernel before compiling it ? You seem to have missed the ALSA module ...

in the kernel source top directory, as root:

Code: Select all

make menuconfig

then go to Device Drivers -> Sound -> Advanced Linux Sound Architecture : say M for most of the relevant stuff, then go further in PCI Devices : select nothing except what is relevant, namely ICEnsemble ICE1712 (Envy24) and optionally your onboard sound if you have (set all this ALSA stuff to M so that modules are created).

Also make sure you have selected FULL PREEMPTION for realtime stuff. That's in
Processor type and features -> Preemption Mode -> Complete Preemption (Real-Time)

[studio32]

have you configured the kernel before compiling it ? You seem to have missed the ALSA module ...

mmh I've done

Code: Select all

make oldconfig

Code: Select all

make xconfig

- Processor type and features> Preemption Mode (Complete Preemption (Real-Time))
- Processor type and features>Timer frequency (1000 HZ)

Nothing specially with ALSA

[thorgal]

see my post before, I updated it.

[studio32]

@ thorgal, thanks for your help.

I thought oldconfig takes over the settings of the generic kernel, and my soundcards works with that kernel, so why to change anything, except the realtime stuff?

You say I have to do it again the whole process? As root? I made the kernel in my /home folder... and use fakeroot for building...

[thorgal]

no, don't get me wrong, you don't need to be root. I just usually do admin tasks and other tweaks as root, kernel stuff included. fakeroot is fine and meant for ppl who don't want to use root.

About the kernel config, I can only presume you used a packaged config file as .config

Inspect the config file you used as a seed for your new kernel and check that the ALSA modules are included. This sounds really strange indeed.

ok mmh will try it tomorrow again...

[studio32]

@torgal, ok mmhh I did oldconfig and did what you said. Nothing was M or Y in ALSA :/
Strange?

It's running now for a second try.

btw what to do if you want to make a realtime kernel which is usable for as much people as possible? If you have to make an realtime kernel for Ubuntu studio for instance.
