HOWTO: Build an RT-application
Hi Remy,
I'd like to update "HOWTO: Build an RT-application" page on the rt wiki[1]. Since your are listed as maintainer, I better ask if my ideas are okay before editing.
1) I would like to get rid of quite outdated information (maybe move it to archive section?) on 'The impact of the Big Kernel Lock'
2) Add 'Don't use priority 99'
3) Don't implement spin locks (use priority inheritance futexes)
4) Avoid slow I/O
5) mmap passing data
6) Be aware of power management: cpufreq, nohz
2) - 5) are stolen from Steven's presentation
cheers,
daniel

Hi Martin,

I'm someone who would have found it very very useful to have an updated HOWTO about a year ago.
If you see missing items in my TODO list please let me know. I am far away to be an expert, but I think I give it a shot and see what the expert think.

The documentation is out of date or nonexistent for anyone new to linux-RT.
Yes, that is the nature of wikis :)

Thanks a lot for doing this.
No problem. I need something like this internally anyway, so why not use a public source :)
cheers,
daniel

It has been a very very long time ago when I wrote that page. (years?) Please take over this page and improve it :-)
I 'improved' it now: Flames and improvements are welcome. In case someone doesn't have an wiki account to fix it up, just post it here and I add it to the wiki.
cheers,
daniel

Should be easy to get an account on the wiki, no need to post here. Improvements / updates and so on, are very much welcome, so thanks!
