====== 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 obsolete in current kernel versions.
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>

* + ext3 cache works fine
Athlon64 2GHz, 1GB RAM, some NVidia board, NVidia Ge''''Force 2 MX 200
* + did not have problems with genirq, unlike on other archs/computers
* - sometimes is was locking in kernel-mode for a long time (5 seconds)

===== 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.
