Re: does the wheezy beta kernel have PREEMPT??

I'm not entirely sure why since I haven't done much kernel compiling and installation since my days of playing with FreeBSD (3.2-3.3 I believe). I'm pretty sure you can remove support for RTC hardware in the kernel config. That may or may not be your problem. You can also try disabling the High Prec...

Re: does the wheezy beta kernel have PREEMPT??

The rt patch is available for 3.2.27, it applies to the RasPi sources and they compile fine, but I can't test the results, because the RasPi sources removed some hardware support needed for QEMU. If you want to test it the patch can be found at http://www.kernel.org/pub/linux/kernel/projects/rt/3.2/...

Also yes I started with vanilla 3.4.11 applied the arm patch then the rt patch. Both patches I used and my config are here http://www.4shared.com/archive/Ow77Oe8S ... _conf.html

Re: does the wheezy beta kernel have PREEMPT??

I patched it with a generic arm patch found at http://xecdesign.com/downloads/linux-qemu/linux-arm.patch It actually patches for ARM11(ARMv6) support on the versatile board, which, from what I've read, is what QEMU is emulating. It's close to a RaspberryPi but not identical. It's the best I have to ...

Re: does the wheezy beta kernel have PREEMPT??

Two updates. I got the kernel to boot the Wheezy image on the downloads page. I only booted to console. I can't get the desktop, but I haven't worked on it for long. I also uploaded the wrong zImage heres the new link http://www.4shared.com/archive/_uwL6S1X ... furl=d1url

Re: does the wheezy beta kernel have PREEMPT??

I have compiled linux-3.4.11 (the newest kernel that I could find real-time patches for) with real-time support. It boots the Arch image available on Raspberry Pi's download page in Qemu. I haven't tried the Debian image. I don't have access to a Raspberry Pi yet so I'm following directions for Qemu...
