AM6 PSI-L Device Descriptions


This chapter provides information on the PSI-L devices in the AM6 SoC. Some System Firmware TISCI messages take device specific inputs. This chapter provides information on the valid values for PSI-L TISCI message parameters.

PSI-L Proxy Device IDs

Some System Firmware TISCI message APIs require the PSI-L Proxy device ID be provided as part of the request. Based on AM6 Device IDs these are the valid PSI-L Proxy device IDs.

PSI-L Proxy Device Name PSI-L Proxy Device ID

PSI-L Source and Destination Thread IDs

This section describes valid PSI-L source and destination thread IDs for each thread type. The thread IDs are used in the PSI-L based TISCI messages.


PSI-L threads marked as reserved for use by DMSC cannot be linked to another thread.
