- | ====== KernelDesktop ====== | ||
- | |||
- | |||
- | ===== kernel-desktop specifications ===== | ||
- | |||
- | |||
- | ==== Main goals: ==== | ||
- | |||
- | * create kernel for desktop computers, oriented to architectures used as desktops: ppc, x86, amd64 (there is no ia64 support) | ||
- | * not so loaded as main PLD kernel, no full grsec, no vserver | ||
- | * add patches improving latency and other tasks useful on desktops | ||
- | |||
- | |||
- | ==== Conditional Builds: ==== | ||
- | |||
- | * preemptrt (**RT**): | ||
- | * [[http://people.redhat.com/~mingo/realtime-preempt/|realtime-preempt]] patch by Ingo Molar\\ this patch contains many changes from [[http://kernel.org/patchtypes/mm.html|-mm]] tree thus kernel using it may be very unstable or unusable | ||
- | |||
- | ck (**CK**): | ||
- | * Con Kolivas [[http://members.optusnet.com.au/ckolivas/kernel/|desktop patches]]\\ those patches are giving nice results, and generally work without problems\\ most of ck-patch parts are disabled when building with RT | ||
- | |||
- | grsec_minimal (**GR**): | ||
- | * grsecurity for ''/proc'': in PLD noone can live without grsecured ''/proc'', even on desktops ;-) | ||
- | |||
- | laptop (**LAP**): | ||
- | * simply changes HZ from default 1000 to 100, this should improve on-batery time, but decreases corectness of some programs using timer a lot (even 'time' in shells is not very reliable)\\ example: played some music with mplayer, time: <file>HZ=100: | ||
- | real 32m24.907s user 0m4.420s sys 0m0.780s | ||
- | HZ=1000: | ||
- | real 32m25.936s user 0m22.736s sys 0m7.582s</file> | ||

- | ===== Series 2.6.19 ===== | ||
- | Not started. CK patch is missing. | ||
- | |||
- | |||
- | |||
- | ---- | ||
- | |||
- | |||
- | |||
- | |||
- | ===== Tips ===== | ||
- | |||
- | * If you are using CK patch check the page to get some info about it. Then install ''schedtool'' and start using ''schedtool -I'' ! | ||
- | * If you own Macintosh PowerPC computer try adding ''noisapnp'' and ''i8042.nopnp'' to kernel cmdline to suppress some ugly warnings about non-existing device. | ||
