kernel 2.6.23 with system timer 1000Hz

Hello,

I'd like to use rosegarden, which requires system timer to be set 1000Hz. The stock 2.6.23 kernel is delivered with 300Hz timer. Hence, I wanted to change that and recompile the kernel. It seemed quite straight-forward, but...

As usually I ran the make menuconfig:

/usr/src/linux-2.6.23-ARCH> make menuconfig
scripts/kconfig/mconf arch/i386/Kconfig
drivers/crypto/Kconfig:54: can't open file "arch/s390/crypto/Kconfig"
make[1]: *** [menuconfig] Error 1
make: *** [menuconfig] Error 2

So, I tried to open the drivers/crypto/Kconfig and to comment out the source directive on line 54. After this, the menuconfig worked and I successfully changed the timer settings. Then, I ran make

/usr/src/linux-2.6.23-ARCH> make
  CHK     include/linux/version.h
  CHK     include/linux/utsrelease.h
make[1]: *** No rule to make target `missing-syscalls'.  Stop.
make: *** [prepare0] Error 2

Now, I'm lost. Do you have an idea what that means? What do I do wrong?

Thanks in advance, Kašpi.

Those are not full sources, just stuff necessary to compile external modules.

Use ABS for that.

OK, that explains a lot :-) Thans, Kašpi.

Hi kaspi. Have you solved this issue? I'd also like a 1000 Hz timer. Have you been able to find a suitable precompiled kernel? I know I can recompile the kernel, but I would like to avoid this. That's the reason why I've moved from Gentoo to Arch: because I was sick of compiling. Thanks

Hello,

I've solved that by compiling my own kernel. There used to be precompiled kernels with 1kHz clock but they seem to have disappeared. But I admit I haven't searched extensively.

On the other hand kernel compilation with ABS was fairly straightforward. There are at least 2 Arch wikipages about kernel compilation, so those I recommend to you.

Good luck, Kaspi.

Yeah, I know... "beyond" was one of these kernels. I might try to compile, I will see how slow it is. I have an old system (Athlon XP 1700+) and compiling a whole kernel can take some time.
Anyway, thanks a lot for your help
