I think Im addicted. I need help!
In this update we added 8 cpus and rewrote the ppc64 pagetable management
code to do lockless inserts and removals (there is still locking at
the pte level to avoid races).
hardware: 32 way logical partition, 1.1GHz POWER4, 60G RAM
kernel: 2.5.7-pre1 + ppc64 pagetable rework
kernel compiled: 2.4.18 x86 with Martin's config
compiler: gcc 2.95.3 x86 cross compiler
make[1]: Leaving directory `/home/anton/intel_kernel/linux/arch/i386/boot'
128.89user 40.23system 0:07.52elapsed 2246%CPU (0avgtext+0avgdata 0maxresident)k
0inputs+0outputs (437084major+572835minor)pagefaults 0swaps
7.52 seconds is not a bad result for something running under a hypervisor.
The profile looks much better now. We still spend a lot of time flushing tlb
entries but we can look into batching them.
