RapidIO II IP Core logical_transport_error, port_failed, and port_degraded Input Signals Trigger Interrupts or Not Irrespective of Interrupt Enables

Description

The RapidIO II IP core Port 0 Control CSR (offset 0x15C) LOG_TRANS_ERR_IRQ_EN, PORT_FAIL_IRQ_EN, and PORT_DEGR_IRQ_EN bits should control whether or not the IP core generates an interrupt in response to the input signals logical_transport_error, port_failed, and port_degraded, respectively.

However, the three register bits have no effect. Instead,

• The logical_transport_error signal always triggers an interrupt.
• The port_failed signal never triggers an interrupt.
• The port_degraded signal never triggers an interrupt.

Resolution

This issue has no workaround.

This issue is fixed in version 14.1 of the RapidIO II MegaCore function.
