--- Comment #5 from Chris Wilson <chris at chris-wilson.co.uk> ---
Well I thought it was part of CONFIG_SECURITY_DMESG_RESTRICT but reading
through, no. igt needs write permission to /dev/kmsg, so check the permission
bits there and keep hunting until running "hostname > /dev/kmsg", the output
appears in dmesg. We expect to see start/stop markers as igt runs through the
subtests, which helps us when reading through the kernel logs to find the
relevant chunks.
