I cloned my MMC card onto a USB stick and updated init.partitions.rc in my initrd to mount sdaX rather than mmblk0pX. Here are the boot times I get: With hmp_data.freqinvar_load_scale_enabled = 1 49s, 46s, 46s With hmp_data.freqinvar_load_scale_enabled = 0 39s, 40s, 37s So whilst the difference is nothing like what I see with MMC, there does still seem to be a significant effect. On the slow booting config, the 'Geiger counter' sound from the power circuitry does sound a bit harsher, perhaps the pattern of cpuidling is different. That could be my imaginations, or a symptom rather than a cause... -- Tixy _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
