2.4.3 Confirmation of HFI status
For confirmation of HFI status, the hfi_read_regs command is useful. As shown in
Example 2-10, the hfi_read_regs command shows the status of many types of registers,
such as window, non-window, cau, nmmu, and performance.
Example 2-10 hfi_read_regs command usage
usage: hfi_read_regs -l hfiX [-Z | {-w win_num | -m | -c | -s cau_slot | -n | -p |
-i}]
Example 2-11 shows the hfi_read_regs sample output.
Example 2-11
# hfi_read_regs -p -l hfi0
