Hi!

I am having problems building a new kernel.. R5E50

1. Downloaded kernel source that cecil posted in a topic something like "So you want kernel sources..."
2. unpacked, linked to linux, linked /usr/src/linux/include/asm-i386 to asm, and copied /boot/config-2.6.18-chw-13 to /usr/src/linux/.config
3. make
4. make modules_install
5. make install
lilo

... if I reboot now... everything seems to work.... except that my capture card(s) does not get initialized.... there is no mentions of ivtv in dmesg, and /dev/video0 does not show up.....

in /proc/interrupts there is no entries with ivtv as there used to be...

.......... now to the fun part...

If I restore /boot/ and /lib/modules and rerun lilo and reboot, everything works again...

if I manually copy the bzImage to /boot/ and rerun lilo, everything still works...
If I run make modules_install it stops working.....

what gets destroyed when I install the modules?!? do I haveto patch the kernel source I got from cecil?

I really need to turn off SMP for my backend (the network card seems to not work as supposed to when SMP is enabled), and for that I need to recompile everything in the kernel (scince the modules have the SMP versioning flag set) (ofcourse, I also wanted to recompile for my processor architecture also, and remove unwanted features.. but primarily, I just want the kernel to work!...)

so.. all-in-all .... I'm asking: how can we compile a working kernel?

I do see "knoppmyth is searching for multimedia devices bla bla bla bla" in the startup, and the capture card do show up in that list... but ivtv does not run anyway... udevd is also started.... no errormessages..... just no traces of ivtv....

Regards // OwL

Just noticed that "make modules_install" on the kernel will delete all the current modules, and then copy the new ones to the right location.... this causes the ivtv, nvidia and some other custom modules to be removed...

Cecil (or someone else who knows): What "extra" modules have been added in knoppmyth, that does not exist in the kernel source?
Where can we get the source for them?

And by the way..... I am having massive problems with packet loss on my ethernet card on R5E50 KM... very strange... I have tried to switch to other network cards, but they do not even initialize properly (they pass self test and seem to be allocated to eth0, but when the system is completely started, eth0 is missing, and no IRQ is assigned to the cards (except from the card that actually initializes, but that card then suffers from massive packetloss)).... This makes it virtually impossible to use that computer for backend/frontend system, scince streaming from the backend is very choppy due to the packetloss.... :((((
No error messages in dmesg, no errors reported in ifconfig... just, plain lost packets.... tried everything.. moved the cards around in the box, disabling IRQ:s, moving IRQ:s, disabling all extra periferals..

The same computer worked flawlessly on R5C KM

Re: Your Ethernet problem

I've been experiencing a lot of problems that may be interrupt related (lost remote keypresses, slow running clock, etc.). Your Ethernet problem might be related. I've been trying everything with no luck. However, I just found this related to issues with boxes unable to keep up with the new higher clock interrupt rate:
Quote:
In standard 2.6 kernels, the timer interrupt rate is fixed at kernel compile time and cannot be changed by command line parameters. You can, however, recompile your kernel with a lower timer interrupt rate. 100Hz is adequate for most applications in a Linux guest. See the documentation for your Linux distribution for detailed instructions on how to build and run a custom kernel. Before recompiling the guest kernel, locate the following line in /usr/src/linux-2.6/include/asm-i386/param.h:

#define HZ 1000


Change the value of HZ to 100:

#define HZ 100
I'm going to try and recompile my kernel this weekend and see what happens (I've never done this before....). I notice you are already successfully recompiling the kernel, so you might want to try this change. Reading elsewhere, a more reasonable value for the clock interrupt rate is probably 250 or 300.

Some related references: hvmware discussion quoted above or More fixes, none of which have worked for me

I checked it out...

but it seems to already be changed for 2.6.18 kernels and onwards..

This is the file from 2.6.18-chw-13
Code:

#ifndef _ASMi386_PARAM_H
#define _ASMi386_PARAM_H

#ifdef __KERNEL__
# define HZ             CONFIG_HZ       /* Internal kernel timer frequency */
# define USER_HZ        100             /* .. some user interfaces are in "ticks" */
# define CLOCKS_PER_SEC         (USER_HZ)       /* like times() */
#endif

#ifndef HZ
#define HZ 100
#endif

#define EXEC_PAGESIZE   4096

#ifndef NOGROUP
#define NOGROUP         (-1)
#endif

#define MAXHOSTNAMELEN  64      /* max length of hostname */
#define COMMAND_LINE_SIZE 256

#endif

I got around to trying this last night and you are partially right. It has been changed, but the default is still 1000 in KM (notice the ifndef).

To rebuild it, edit the .config in the source drive before making. Change:
Code:
# CONFIG_HZ_100 is not set
# CONFIG_HZ_250_NODEFAULT is not set
CONFIG_HZ_1000=y
CONFIG_HZ=1000
To:
Code:
CONFIG_HZ_100=y
CONFIG_HZ_250_NODEFAULT=y
# CONFIG_HZ_1000=y
# CONFIG_HZ=1000
When you run make, it will ask for the HZ to use.

Bad news is.... it didn't help my problem.

Hi!

I just managed to build kernel 2.6.20.4..

In my case it was just doing:

get the 2.6.20.4 kernel source from kernel.org, unpack, link to linux and copy the 2.6.18 config to the new kernel. Turned off SMP (Scince I thought my problem was related to that), added APIC support on uni processors and changed processor architecture to match my backends CPU.

Downloaded the latest ivtv source and latest firmwares (I unpacked them in the hotplug directory specified in the ivtv readme's). (the new ivtv needs new firmwares)

Then I read the ivtv install.README, and in there I got some things to change in the kernel config also... Did those changes.. (some v4l / multimedia devices something something, that was supposed to be turned off when using 2.6.20 kernels)

then I made:

Code:
cd /usr/src/linux
make
make modules_install
make install (but don't run lilo yet)
cd ..
tar -xvzf ivtv-0.10.1.tar.gz
cd ivtv-0.10.1
make
make install
apt-get install yaird
yaird -o /boot/initrd.img-2.6.20.4 2.6.20.4
nano /etc/lilo.conf (and added references to the new kernel and the new initrd image, make sure that you save the old kernel and initrd image references in another bootup choise, if the new kernel would blow up during boot)
lilo
reboot


Ofcourse the above might not be complete,, just wrote it of the top of my head (or do you say stack?,.. ;) )

Then I rebooted.....

but.. the bad news.... still packet losses, but I now only lose a couple of packets per 1000 I send.... but still not good.... (still unwatchable on the frontend, scince it skips all the time)

I have now managed to get me a couple of new network interfaces to try out... Will do that during the day...

Does anyone else have any tip to what choices in the kernel config that might affect our problems...

Regards // OwL

I have now been experimenting a bit...

Changed to other ethernet cards, but they don't seem to initialize properly.. :(

They show up during boot, and is given eth0, but when the bootup is finished, no eth0 exists...

if I force the realtek card to 10MBit full duplex, I lose no packets.... but... scince I have 100MBit internet connection, running on 10Mbit is no option,.. :(

Why is the only ethernet card that works (somewhat.... ) the realtek card?!?!

I think I will set this to SOLVED, scince I have actually managed to make myself some new kernels........ and start another thread in the linux general forum instead...

I have tweaked like a madman on the 2.6.20.4 kernel but I still suffer from packet loss.. :(

I now get 90-100MBit Rx speed and only about 15-20MBit Tx speed..... but the packet loss is down below 1% ... but it is still unusable for a frontend/backend system...

hey... wait.... what if.. hmmm... could it be like that?... my internet connection is 100/10 wonder if that plays any role in this?..... naaaa.. hardly.. internal network.... traceroute shows only one hop...

damn, this is driving me crazy....

Regards // R
