To enable generating trace messages for an iRISC, the trace_mask register must be set according

to the specifications in the device’s Programmer’s Reference Manual. Setting or clearing bits of

the trace_mask register enables or disables, respectively, the generation of specific types of trace

messages. The TRACE_MASK parameter must be a hexadecimal or decimal number and its value

will be written into the trace_mask register. Changing trace_mask will not change or remove mes-

sages previously stored in the trace buffer, so disabled types of messages can still be displayed by

itrace if they were previously generated.

Example:

For Linux device names should be listed with the /dev/mst prefix. For Windows, no pre-

fix is required.

itrace -d /dev/mst/mt25204_pci_cr0 --nomap -m 0xffffffff tpt

This generates output regarding the sequence numbers, timestamps, and records of operations, such

as the following:
