At last weeks' LPC, there was some interest in my patches for Auto/Lazy Migration to improve locality and possibly performance of unpinned guest VMs on a NUMA platform. As a result of these conversations I have reposted the patches [4 series, ~40 patches] as RFCs to the linux-numa list. Links to threads given below. I have rebased the patches atop 3Nov10 mmotm series [2.6.36 + 3nov mmotm]. The patched kernel builds, boots and survives some fairly heavy testing on an 8 node istanbul x86_64. Under heavy load, I do encounter a race in the somewhat optional migration cache. Currently this generates a warning and carries on, but the one migration cache entry and related page is then wedged. This would need to be resolved. The series/threads in the order applied: [PATCH/RFC 0/14] Shared Policy Overview http://markmail.org/message/trvpl3t7gimvwht6 [PATCH/RFC 0/8] numa - Migrate-on-Fault http://markmail.org/message/mdwbcitql5ka4uws [PATCH/RFC 0/11] numa - Automatic-migration http://markmail.org/message/zik3itmqed65mol2 [PATCH/RFC 1/5] numa - migration cache - core implementation http://markmail.org/message/xvck7enyezx6chyi RESEND: [PATCH/RFC 1/5] numa - migration cache - core implementation http://markmail.org/message/xgvvrnn2nk4nsn2e resend to add back the patch description missing from 1st attempt. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
