So reverting 17c91487364f (PCI/ASPM: Do not initialize link state when aspm_disabled is set) on top of 4.20-rc4 makes the problem go away. I guess that the device in question needs pcie_aspm_cap_init() to be called for it even though the FADT says "NO_ASPM". Thanks, Rafael ^ permalink raw reply [flat|nested] 8+ messages in thread

With a good kernel (v4.19 or v4.20-rc with 17c91487364f reverted), would you mind collecting "lspci -vv" output, the dmesg log with "pci=earlydump", and the FADT dump? I'm interested in the initial state of the device at handoff from BIOS, and what Linux changes even when aspm_disabled is set. If we can't figure out a way to fix both this issue and the one fixed by 17c91487364f, I guess the fallback will be to revert 17c91487364f since it's better to allow a system that was previously broken to remain broken than it is to break a system that previously worked. But obviously I hope we can figure out a solution that fixes both cases. > > When it doesn't work, it doesn't generate any interrupts on device insertion > > and removal and this seems to be reproducible 100% of the time. > > So reverting 17c91487364f (PCI/ASPM: Do not initialize link state when > aspm_disabled is set) on top of 4.20-rc4 makes the problem go away. > > I guess that the device in question needs pcie_aspm_cap_init() to be > called for it even though the FADT says "NO_ASPM". ^ permalink raw reply [flat|nested] 8+ messages in thread

Well, depending on how many systems are affected by the issues fixed by 17c91487364f IMO. Arguably, if the FADT says "NO_ASPM", then the platform should not need the OS to initialize ASPM to work. I guess a manual workaround (like an extra kernel command line option or similar) should suffice in this particular case. > But obviously I hope we can figure out a solution that fixes both > cases.

I hope Patrick has a chance to look at this. Per the bugzilla mentioned in 17c91487364f, it fixes a problem with a custom proprietary PCIe device, and there's a lot of good detailed analysis there, so hopefully we can figure out a way to address both situations. ^ permalink raw reply [flat|nested] 8+ messages in thread

I queued up a revert on for-linus, since we haven't made any progress on this yet. I'll be on vacation much of this week, but I want to get the revert (or better, a fix if we can find one) in before -rc6 comes out next Sunday. If we figure out a fix before then, I'll drop the revert and use the fix instead. Bjorn ^ permalink raw reply [flat|nested] 8+ messages in thread
