Programming Details

Error Notification and Handling

The Raven ASIC and Falcon chip set can detect certain hardware errors and can be programmed to report these errors via the RavenMPIC interrupts or Machine Check Interrupt. Note that the TEA∗ signal is not used at all by the MVME2300 series. The following table summarizes how hardware errors are handled by the MVME2300 series boards:

Table 5-5. Error Notification and Handling

 

 

Cause

Action

 

 

Single-bit ECC

Store: Write corrected data to memory.

 

Load: Present corrected data to the MPC master.

 

Generate interrupt via RavenMPIC if so enabled.

 

 

Double-bit ECC

Store: Terminate the bus cycle normally without writing to DRAM.

 

Load: Present un-corrected data to the MPC master.

 

Generate interrupt via RavenMPIC if so enabled.

 

Generate Machine Check Interrupt to the processor(s) if so enabled.

 

 

MPC Bus Time Out

Store: Discard write data and terminate bus cycle normally.

 

Load: Present undefined data to the MPC master.

 

Generate interrupt via RavenMPIC if so enabled.

 

Generate Machine Check Interrupt to the processor(s) if so enabled.

 

 

PCI Target Abort

Store: Discard write data and terminate bus cycle normally.

 

Load: Return all ones and terminate bus cycle normally.

 

Generate interrupt via RavenMPIC if so enabled.

 

Generate Machine Check Interrupt to the processor(s) if so enabled.

 

 

PCI Master Abort

Store: Discard write data and terminate bus cycle normally

 

Load: Return all ones and terminate bus cycle normally

 

Generate interrupt via RavenMPIC if so enabled

 

Generate Machine Check Interrupt to the processor(s) if so enabled

 

 

PERR# Detected

Generate interrupt via RavenMPIC if so enabled

 

Generate Machine Check Interrupt to the processor(s) if so enabled

 

 

SERR# Detected

Generate interrupt via RavenMPIC if so enabled

 

Generate Machine Check Interrupt to the processor(s) if so enabled
