The Broadcom iProc IDM device allows control and monitoring of ASIC internal
bus transactions. Most importantly, it can be configured to detect bus
transaction timeout. In such case, critical information such as transaction
address that caused the error, bus master ID of the transaction that caused
the error, and etc., are made available from the IDM device.

This seems to have many of the features of an EDAC device reporting
uncorrectable errors.

Is there any reason why it is not implemented as such?

Thanks,

I thought EDAC errors (in fact, in our case, that's fatal rather than uncorrectable) are mostly for DDR. Is my understanding incorrect?

Thanks,
