It creates a 'kernel.debug' compiled with -g as well as a normal kernel. You can use 'make install.debug' to install the debug kernel. It doesn't have any impact on the normal kernel at all. > PREEMPTION as I understand it should have been removed from the kernel > config file.

It allows threads that are in the kernel to be preempted by higher priority threads. It helps with interactivity and allows interrupt threads to run sooner rather than waiting.

I can confirm debug symbols is still in the kernel, but that is most likely used for backtraces and debugging when a kernel panic happens. This is instead of asking the user who had a kernel panic to rebuild with debugging to debug it. PREEMPTION as I understand it should have been removed from the kernel config file. It should have been removed from the GENERIC config file after RELENG_8_0_RELEASE tag is made. I don't know what your tag is when you update. Perhaps you're copying or using a config file from the BETA or RC days? I'll help until I can't help no more with your issue. --Tim ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Debug still in kernel
Hello all, I am currently tracking RELENG_8_0. I did a csup last night and noticed that debug is still enabled in the GENERIC kernel. I thought debugging was supposed to be left out once the 8 branch went RELEASE? Can anyone shed light on this subject? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
