Just thought I'd let you know that CFS is working on the PS3
neutrino boot # dmesg Using PS3 machine description Page orders: linear mapping = 24, virtual = 12, io = 12 Starting Linux PPC64 #1 SMP Fri May 18 09:26:38 UTC 2007 ----------------------------------------------------- ppc64_pft_size = 0x14 physicalMemorySize = 0x8000000 ppc64_caches.dcache_line_size = 0x80 ppc64_caches.icache_line_size = 0x80 htab_address = 0x0000000000000000 htab_hash_mask = 0x1fff ----------------------------------------------------- Linux version 2.6.22-rc1-cfs-v13 (root@localhost) (gcc version 4.1.1 (Gentoo 4.1.1-r3)) #1 SMP Fri May 18 09:26:38 UTC 2007
It feels more responsive but I shall do more testing and see if there are any real benefits
