| - | ===== 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: ==== | ||
| - | |||
| - | * preemptrd (RT): | ||
| - | * [[http://people.redhat.com/~mingo/realtime-preempt/|realtime-preempt]] patch by Ingo Molar\\ this patch contains many changes from -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> | ||
