[Bug 1682711] Re: PCIe ASPM disabled even when enabled in FADT and pcie_aspm=force / setpci used
Kai-Heng, Yes, but with ASPM disabled unfortunately even ASPT doesn't help enough. :-( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1682711 Title: PCIe ASPM disabled even when enabled in FADT and pcie_aspm=force / setpci used To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1682711/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Is cooling the NVMe is your goal? 4.10.0-19 already has NVMe APST support. No sure if PCIe ASPM matters though. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1682711 Title: PCIe ASPM disabled even when enabled in FADT and pcie_aspm=force / setpci used To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1682711/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Talking to Matthew Garrett on irc he said that he thinks this may only be fixable via an UEFI change. 04:33 < ccheney> anyone know if it is possible to change a setting in LnkCap on a pci device? My pcie ports apparently have 'ASPM not supported' set and I need to turn it on somehow 04:33 < ccheney> its on a skylake system 04:35 < mjg59> ccheney: It's set by either the firmware or the chipset itself 04:35 < ccheney> the FADT doesn't have aspm disabled but its not enabled on the ports or the devices, setpci seems to be able to turn it on for LnkCtl but LnkCap seems to be overriding it? 04:35 < mjg59> lnkcap represents what the link is capable of 04:35 < ccheney> mjg59: is there anyway to force enable it afterwards via initrd (similar to acpi replacement tables) or something like that? 04:35 < mjg59> ccheney: Nope 04:35 < ccheney> ugh :( 04:35 < mjg59> Not that I know of -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1682711 Title: PCIe ASPM disabled even when enabled in FADT and pcie_aspm=force / setpci used To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1682711/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The setpci commands I used modified the LnkCtl option but not the LnkCap values. I'm not sure but suspect that the LnkCap values are what are causing the problem. -- LnkCap: Port #17, Speed 8GT/s, Width x4, ASPM not supported, Exit Latency L0s <1us, L1 <16us ClockPM- Surprise- LLActRep+ BwNot+ ASPMOptComp+ LnkCtl: ASPM Disabled; RCB 64 bytes Disabled- CommClk+ ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt- LnkCap: Port #7, Speed 8GT/s, Width x1, ASPM not supported, Exit Latency L0s <1us, L1 <16us ClockPM- Surprise- LLActRep+ BwNot+ ASPMOptComp+ LnkCtl: ASPM Disabled; RCB 64 bytes Disabled- CommClk+ ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt- vs LnkCap: Port #17, Speed 8GT/s, Width x4, ASPM not supported, Exit Latency L0s unlimited, L1 <16us ClockPM- Surprise- LLActRep+ BwNot+ ASPMOptComp+ LnkCtl: ASPM L0s L1 Enabled; RCB 64 bytes Disabled- CommClk- ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt- LnkCap: Port #7, Speed 8GT/s, Width x1, ASPM not supported, Exit Latency L0s unlimited, L1 <16us ClockPM- Surprise- LLActRep+ BwNot+ ASPMOptComp+ LnkCtl: ASPM L0s L1 Enabled; RCB 64 bytes Disabled- CommClk- ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt- -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1682711 Title: PCIe ASPM disabled even when enabled in FADT and pcie_aspm=force / setpci used To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1682711/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
