| |
The patchset contains mainly scalability and NUMA stuff, and anything else that stops things from irritating me. It's meant to be pretty stable, not so much a testing ground for new stuff.
I'd be very interested in feedback from anyone willing to test on any platform, however large or small.

Since 2.5.58-mjb1 (~ = changed, + = added, - = dropped)
~ summit1 James Cleverdon / John Stultz ~ summit2 James Cleverdon / John Stultz ~ summit3 James Cleverdon / John Stultz ~ summit4 James Cleverdon / John Stultz ~ summit5 James Cleverdon / John Stultz ~ min_numasched Martin J. Bligh ~ numasched_ilb Michael Hohnbaum + numa_rebalancer Erich Focht + mpc_apic_id Martin J. Bligh + doaction Martin J. Bligh + vm_enough_memory Martin J. Bligh + discontig_x440 Pat Gaughen / Chandra + topo_hack Pat Gaughen
Notes: NUMA scheduler is fully there now. Please let me know of tuning data. Summit code should be fully working, with no more interrupt distribution problems. Discontigmem code for x440 may not work without a small ACPI fix.
Pending: Speed up page init on boot (Bill Irwin) Notsc automatic enablement (someone, please ... anyone?) scheduler callers profiling (Anton) PPC64 NUMA patches (Anton) Lockless xtime structures (Andi) P4 oprofile support (movement) Child runs first (akpm) New starfire driver (Ion) New qlogic driver (Badari ??)
