-====== 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: ==== 
- 
-  * 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>​
