    Default Motherboards With Broken ASPM On Linux

    Phoronix: Motherboards With Broken ASPM On Linux

    One of the many OpenBenchmarking.org features that haven't yet been fully taken advantage is the opportunities presented by the vast collection of system hardware/software information and logs that have been submitted to this collaborative testing platform from Phoronix Media. OpenBenchmarking.org is much more than just being a storage place for benchmark results. After writing a simple plug-in this morning, here's a list of many motherboards that have broken PCI-E Active State Power Management support from their BIOS, which can lead to greatly increased power consumption under Linux...

    My exact board isn't there but the Gigabyte P55A-UD3 is. I have the UD6 so it seems likely that I'm affected. Just as well I've been running with pcie_aspm=force for a while.

    Default My Gigabyte EX58-UD3R is affected too

    Running with pcie_aspm=force seems to sort it out, though. (No sign of instability...)

    If your motherboard isn't on the list and you're affected, that means you should be running more benchmarks via the Phoronix Test Suite and opting to submit data to OpenBenchmarking.org

    " To ensure some quality, each motherboard in the list had at least two unique submissions where ASPM could be detected as not working due to the ACPI table. "

    What if they fix it in a BIOS update AFTER people go and make their submissions? The board would still be counted even though it shouldn't? I'd think you should be looking for cases where NO submissions say that the ASPM works on that board. Finding just two different submissions that say it doesn't work really isn't that helpful, IMO as mobo manufs. can claim they fixed it later.

    I know this was written more in a "let's show what pts can do" way, but:
    Toshiba Portable PC
    Sony VAIO
    are too vague.

    Unfortunately it's limited to what the motherboard vendor exposes from their BIOS as their vendor and product/model strings...

    My Lenovo W520 (4270cto) is affected. The "pcie_aspm=force" workaround works fine though.

    What factors are you using to indicate that ASPM is broken on a given motherboard?

    Not surprised that there are a crapload of Asus boards on the list given my experience dealing with their bios engineers who despite have all the proof in the world that something is broken won't listen to anyone until the issue becomes an epidemic.
