const char * log_prefix ()Defined at line 54 of file ../../src/media/audio/drivers/intel-hda/controller/intel-dsp-ipc.cc
void HardwareDspChannel (fbl::String log_prefix, MMIO_PTR adsp_registers_t * regs, std::optional<std::function<void (NotificationType)>> notification_callback, zx::duration hardware_timeout)Create an IPC object, able to send and receive messages to the SST DSP.
|regs| is the address of the ADSP MMIO register set in our address space.
|hardware_timeout| specifies how long we should wait for hardware to respond
to our requests before failing operations.
