AM65X_SR1 Ring Accelerator Device Descriptions

Introduction

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

Ring Accelerator Device IDs

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

Ring Accelerator Device Name Ring Accelerator Device ID
AM6_DEV_NAVSS0_RINGACC0 187
AM6_DEV_MCU_NAVSS0_RINGACC0 195

Ring Accelerator Ring Indices

This section describes valid Ring Accelerator ring indices for each ring type. The ring index and type ID are used in some Ring Accelerator based TISCI messages.

Warning

Resources marked as reserved for use by DMSC cannot be assigned to a host within the RM Board Configuration resource assignment array. The RM Board Configuration is rejected if an overlap with a reserved resource is detected.
