Abstract
One disclosed method includes communicating with a kernel running on a primary processor, by a second processor, in response to detection of a state change; performing a hardware operation, in response to the state change, using the kernel without waking user space on the primary processor, where the user space remains suspended; and resuming a sleep mode of the primary processor by suspending the kernel after the hardware operation is completed. One example of a hardware operation is modification of display data on a touchscreen display. The method of operation may perform the hardware operation using the kernel without waking hardware drivers other than a hardware driver related to the hardware operation.
