AM275X PSI-L Device Descriptions¶
Introduction¶
This chapter provides information on the PSI-L devices in the AM275X 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 AM275X Device IDs these are the valid PSI-L Proxy device IDs.
| PSI-L Proxy Device Name | PSI-L Proxy Device ID |
|---|---|
| AM275X_DEV_DMASS0 | 25 |
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.
Warning
PSI-L threads marked as reserved for use by TIFS cannot be linked to another thread.
