Hi Geoff and Arnd. I'm wondering if it is better to turn on CONFIG_SCHED_SMT or not, in Cell B.E. platforms. I realized that it's turned off in ps3defconfig, but turned on in cell_defconfig. I know Cell B.E has SMT but, I'm not sure how CONFIG_SCHED_SMT works with Cell B.E in details. Regards, Hiroyuki.
