+====== 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>
+More patches:
+  * [[http://www.suspend2.net/|suspend2]]
+  * [[http://dev.gentoo.org/~spock/projects/vesafb-tng/|vesa-tng]]
+  * [[http://dev.gentoo.org/~spock/projects/gensplash/|fbsplash]] or [[http://www.bootsplash.org/|bootsplash]]
+  * [[http://www.namesys.com/v4/v4.html|reiser4]] and [[http://squashfs.sourceforge.net/|squashfs]]

+===== 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.
