[luau] kernel build question

2002-07-30 Thread Lou Rickard
Sorry, this is probably a dumb question. I've downloaded the kernel source for the 2.4.17 kernel. I've built the kernel, installed it, and successfully booted to it. So, what I'm suddenly wondering is, what to do with the /usr/include folder. Aren't those include files specific to the previous

[luau] compiler optimization?

2003-05-15 Thread Lou Rickard
A friend of mine reccommended that I play around with compiler optimizations a bit to see what happens. I was a little surprised. I have an application that's about 10k lines of C code written for linux. It's multi-threaded. It doesn't do any complicated math. It compiles to about 1.8MB. Comp

[luau] applying patches to RH kernels, RH and 2.6 kernel

2003-10-09 Thread Lou Rickard
Specifically, I'm trying to patch the 2.4.20-20.8 kernel with rml's preemptible kernel patch, but it's failing. I've tried going through and fixing the errored lines by hand, but no luck. And now I'm trying to find or figure out a methodical way of creating of doing this. Any ideas? I haven't b

[luau] measuring sustained disk rates

2003-10-13 Thread Lou Rickard
Is there a tool for measuring sustained disk rates? I'm trying to think up or find a way to test the long term to-disk performance of a system I have (scsi disks set to raid-0), but haven't been able to find anything that quite fits. The system is already fully loaded (no empty partition space),

[luau] include files

2004-03-01 Thread Lou Rickard
How do, or should, the include files in /usr/include relate to the include files in /usr/src/linux/include? If you upgrade your kernel, should the /usr/src/linux/include/linux/ files replace your /usr/include/linux files? It seems like they would, and yet, my system seems to run fine without doin

[LUAU] pthreads priority question

2005-01-25 Thread Lou Rickard
I was writing a multi-threaded program, and was using pthread_setschedparam() to boost the priority to something pseudo-realtime, when I got stumped on a question: I want my program to run at a higher level priority than standard, in fact I want it to run at as high a priority level as possible.
