| |
Hello again. This version of the page coloring patch implements "stealth mode", i.e. is as minimal as possible. There are many cleanups, and a few mods for the 2.5 series kernel.
The biggest change is that the hot/cold per-cpu lists are individually colored now, and the patch has the effect of randomizing the cache colors of pages pumped into the per-cpu lists. The lists are still lifo and still favor pages just freed.
No difference in kernel compile time on the K7 system I have; I suspect that decoupling allocation of pages from allocation of pages to processes dilutes the effectiveness of page coloring, but all of the schemes I can think of to enforce page coloring to processes are much more complicated than the one used by this patch.
Patch with /proc output:
