Hmm.  Is the difference simply changing the PCIEASPM config symbol, or
are you booting with command-line arguments like "pcie_aspm=off"?

What's the specific PME bit that changes in the root ports?  Can you
collect the "sudo lspci -vvxxxx" output with and without ASPM?

The capability bits are generally read-only as far as the PCI spec is
concerned, but devices have implementation-specific knobs that the
BIOS may use to change things.  Without CONFIG_PCIEASPM, Linux will
not request control of LTR, and that could cause the BIOS to change
something.  You should be able to see the LTR control difference in
the dmesg logging about _OSC.

We should probably remove the "if EXPERT" from the PCIEASPM kconfig.
But I would expect PME to work correctly regardless of PCIEASPM, so
removing "if EXPERT" doesn't solve the underlying problem.

Rafael, does this ring any bells for you?  I don't remember a
connection between PME and ASPM, but maybe there is one.

Only difference is the config symbol. My command line is plain and simple:

Command line: initrd=\intel-ucode.img initrd=\initramfs-linux.img root=/dev/sda2 rw

lspci output w/ and w/o ASPM is attached incl. a diff.
Here comes the _OSC difference.

w/o ASPM

[    0.386063] acpi PNP0A08:00: _OSC: OS supports [ExtendedConfig Segments MSI HPX-Type3]
[    0.386918] acpi PNP0A08:00: _OSC: not requesting OS control; OS requires [ExtendedConfig ASPM ClockPM MSI]

w/ ASPM
[    0.388141] acpi PNP0A08:00: _OSC: OS supports [ExtendedConfig ASPM ClockPM Segments MSI HPX-Type3]
[    0.393648] acpi PNP0A08:00: _OSC: OS now controls [PME AER PCIeCapability LTR]

It's at least interesting that w/o ASPM OS doesn't control PME and AER.

Yeah, that makes sense.  I can't remember the details, but I'm pretty
sure there's a reason why we ask for the whole set of things.  Seems
like it solved some problem.  I think Matthew Garrett might have been
involved in that.

ACPI_PCIE_REQ_SUPPORT was introduced with 415e12b23792 ("PCI/ACPI:
Request _OSC control once for each root bridge (v3)") in 2011.
It's linked to the following bug report:
https://bugzilla.kernel.org/show_bug.cgi?id=20232

I can't say whether there's a chance that the proposed patch would
bring back the issue discussed at that time.

If somebody thinks that the proposed patch isn't the right solution,
then presumably the following needs to be touched.

	if ((support & ACPI_PCIE_REQ_SUPPORT) != ACPI_PCIE_REQ_SUPPORT) {
		decode_osc_support(root, "not requesting OS control; OS requires",
				   ACPI_PCIE_REQ_SUPPORT);
		return;
	}

	control = OSC_PCI_EXPRESS_CAPABILITY_CONTROL
		| OSC_PCI_EXPRESS_PME_CONTROL;

This was https://bugzilla.redhat.com/show_bug.cgi?id=638912 - some 
firmware misbehaves unless you pass the same set of supported

Current situation means that PME is unusable on all systems where
pcie_aspm_support_enabled() returns false, what is basically every
system except EXPERT mode is enabled and CONFIG_PCIEASPM is set.
So we definitely need to do something.

One question is whether the system from the 10yr old bug report
actually depends on OSC_PCI_EXPRESS_LTR_CONTROL control, or whether
some other change in recent years fixed the issue.
Not sure whether the system is still available for re-testing.

If worst case we have 10yr old systems breaking with a new kernel
then we still would have the workaround to enable CONFIG_PCIEASPM
on that system.

CONFIG_PCIEASPM is default y. I don't think there's huge value in 
adding complexity to deal with it being disabled, given that the kernel 
is then in a configuration that no vendor is testing against. There are 
existing runtime mechanisms to disable it at runtime.

It *was* default y. This changed with a914ff2d78ce ("PCI/ASPM: Don't
select CONFIG_PCIEASPM by default") and that's what triggered the
problem. If there's no easy solution, then maybe it's best to revert
the change for now.

Oh, sorry, I was looking at mainline. CONFIG_PCIEASPM should 
*definitely* be enabled by default - platforms expect the OS to support 
it. If we want to get rid of default y then I think it'd make more sense 
to have a CONFIG_DISABLE_PCIEASPM that's under EXPERT, and people who 
really want to disable the code can do so.

I think the fact that the EXPERT didn't get removed in the above bug
is a defintive bug.  But I'd go further and think the CONFIG_PCIEASPM
option should be removed entirely.  There is absolutely no good reason
to not build this small amount of code if PCIe support is enabled.

That might be a good solution.  I don't really want a situation where
leaving CONFIG_PCIEASPM unset is "known to break PME."

ASPM support has historically been fragile, and it's actually a
significant amount of code (~10KB on my x86), which is larger than
many other things for which we have config options.  But we do have
boot-time and run-time ways to disable it.

Another possibility might be to make it so Linux always advertises
ASPM support, but doesn't actually *do* anything unless
CONFIG_PCIEASPM is set.  I don't think advertising ASPM support means
the OS is required to change whatever configuration firmware did.
