Bug Description
I was running the fwts aspm on some new kit and I got the following results:
PCIe ASPM check.
-------
Test 1 of 2: PCIe ASPM ACPI test.
PCIE ASPM is not controlled by Linux kernel.
ADVICE: BIOS reports that Linux kernel should not modify ASPM settings that BIOS configured. It can
be intentional because hardware vendors identified some capability bugs between the motherboard and
the add-on cards.
Test 2 of 2: PCIe ASPM registers test.
WARNING: Test 2, RP 00h:1Ch.01h L0s not enabled.
WARNING: Test 2, Device 02h:00h.00h L0s not enabled.
PASSED: Test 2, PCIE aspm setting matched was matched.
Is it possible for the warning messages to have a little more explanation using fwts_advice() as I'm not sure what the warning message really means w/o looking it up in the documentation.
Thanks!
