Hi, In this patch series we use winkle for offlined cores. I successfully tested the working of this with subcore functionality. Test scenario was as follows: 1. Set SMT mode to 1, Set subores-per-core to 1 2. Offline a core, in this case cpu 32 (sending it to winkle) 3. Set subcores-per-core to

Fast sleep is an idle state, where the core and the L1 and L2 caches are brought down to a threshold voltage. This also means that the communication between L2 and L3 caches have to be fenced. However the current P8 chips have a bug wherein this fencing between L2 and L3 caches get delayed by a cpu
