Description

DPA Outbox Blocking-Mode

As of firmware v32.43.2026, when the switch DPA Outbox configuration is in non-blocking mode, where DPA Outbox requests complete immediately (do not wait for completion), DPA Kernel, FlexIO SDK and DPA applications should use the "busy" bit check before performing DPA Outbox operations.

To avoid any issues, it is recommended to update the firmware version together with the FlexIO SDK and DPA Applications.

DPA Thread Context

Due to performance optimization, as of firmware v32.43.2026, DPA Thread context is changed in the DPA Kernel and such change will affect DPA applications.

To avoid any issues, it is recommended to update the firmware version together with the FlexIO SDK and DPA Applications.
