Hi all,
As suggested in this wiki page ( http://www.omappedia.org/wiki/Power_Management_Debug_and_Profiling#Tracing_o...), I tried to use the pm_debug debugfs. However, I don't understand the bottom half of the output. If I type "cat /sys/kernel/debug/pm_debug/count", the bottom half of the output looks like this: per_clkdm->per_pwrdm (11) usbhost_clkdm->usbhost_pwrdm (0) cam_clkdm->cam_pwrdm (0) dss_clkdm->dss_pwrdm (0) core_l4_clkdm->core_pwrdm (8) core_l3_clkdm->core_pwrdm (4) d2d_clkdm->core_pwrdm (0) sgx_clkdm->sgx_pwrdm (0) iva2_clkdm->iva2_pwrdm (0) neon_clkdm->neon_pwrdm (0) mpu_clkdm->mpu_pwrdm (0) prm_clkdm->wkup_pwrdm (0) cm_clkdm->core_pwrdm (0) I tried to google what these mean, but found nothing. Please help! Thanks.
