alsa-devel-bounces@alsa-project.org Sender: "Alsa-devel" Implement IRQ handlers for immediate and delayed replies and notifications. Communication is synchronous and allows for serialization of maximum one message at a time. DSP may respond with ADSP_PENDING status for a request - known as delayed reply - and when situation occurs, framework keeps the lock and awaits upcoming response through IPCD channel which is handled in bottom-half. Immediate replies spawn no BH at all as their processing is very short.

Blocks are transferred to SRAM - either IRAM or DRAM - via DW DMA controller. Once basefw is booted, ownership of DMA transfer is lost in favour of DSP. Hosts reponsibilities don't end on initial block allocation and binary transfer. During Dx transitions host must store FW runtime context from DRAM before putting AudioDSP subsystem into lower power state. Said context gets flashed after D0 entry to bring DSP right where it was just before suspending. Load and restore procedures are finalized with SRAM power gating and adequate clock level selection. This power gates unused EBBs and clock speed effectively reducing power consumption.

This is represented by 'catpt_topology' member. Implementation covers all available pin types: - system playback and capture - two offload streams - loopback (reference) - bluetooth playback and capture PCM DAI operations differentiate between those pins as some (mainly offload) are to be handled differently - DSP expects wp updates on each notify_position notification. System playback has no volume control capability as it is routed to mixer stream directly. Other primary streams - capture and two offloads - offer individual volume controls. Compared to sound/soc/intel/haswell this configures SSP device format automatically on pcm creation.
