Subject: Lost PCIe PME after a914ff2d78ce ("PCI/ASPM: Don't select CONFIG_PCIEASPM by default")
Date: Thu, 28 May 2020 23:44:26 +0200 [thread overview]
Message-ID: <2e1ee784-7493-284b-96f9-96b2e0c4b817@gmail.com> (raw)
For whatever reason with this change (and losing ASPM control) I also
loose the PCIe PME interrupts. This prevents my network card from
resuming from runtime-suspend.
Reverting the change brings back ASPM control and the PCIe PME irq's.
Affected system is a Zotac MiniPC with a N3450 CPU:
PCI bridge: Intel Corporation Celeron N3350/Pentium N4200/Atom E3900 Series PCI Express Port A #1 (rev fb)
