help
This driver tracks ADSP sleep statistics while interfacing with
different userspace clients making use of ADSP. Based on the
activity notifications from these userspace clients, the driver
detects and logs sleep violations from ADSP subsystem. The driver
uses master stats from ADSP subsystem stored in SMEM.
