Linux I don't actually have a reason for trying to build a Linux kernel with the CONFIG_PREEMPT_RT patch set. There's no way I can even measure the impact of it. Still, I felt like having a "real-time" Linux box, and set out to make one. Little did I know how difficult it would be to even get started.

The "O=/path/to/build_dir" option just puts the output somewhere else. This isn't especially useful, but it made me feel better. I hate having all the source and binaries jumbled up.

Interesting to know about the compile time. It was longer than I expected, but not a LOT longer. I'll have to see what I can do to trim it down.

Note that I was in a virtual machine. My experience has been the a VM has virtually no impact on purely processor-intensive tasks, but I only gave the VM 1 processor, which is why I didn't use the -jn option.
