Scripts to perform fuzz testing on the PCIe exposed space
To read a PCIe configuration space:
python reg_read.py <DEVICE_ID>
To write to a PCIe configuration space:
python reg_write.py -d=<DEVICE_ID> -r=basic -n=new -o=serial
Display help options:
python reg_write.py -h
-d=: Device ID -r=: Range of config space (basic = 64 byes, full = 256 bytes, extended = 4096 bytes) -n=: Next test type (new = do not ignore failing registers, cont = ignore previously failed registers) -o=: Order registers are being tested (serial = test registers in corresponding order from 0, random = test registers randomly -s=: Registers to be skipped in the next program run. Provide hexadecimal register value(s) separated with a comma (',') -i=: Integer value for the number of times the test should repeat with the same parameters -h: Help section with list of possible input commands.
To rewrite a pattern to the configuration space, create a pattern_file and run:
python pattern_scripts/reg_write_pattern.py <device_id>
An example pattern file can be found in the pattern_scripts subfolder.
