            Bug ID: 214259
           Summary: Discrete Thunderbold Controller 8086:1137 throws DMAR
                    and XHCI errors and is only partially functional
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.13.12 and 5.14-rc7
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: USB
          Assignee: [email protected]
          Reporter: [email protected]
        Regression: No

Affected devices: Clevo X170KM Barebone (I have one here) and according to this reddit thread that describes the exact same problem a Thunderbold PCIe exapansion card:
https://www.reddit.com/r/Thunderbolt/comments/ohjakr/asus_thunderboltex_4_linux_compatability/

The Clevo does not use the build in thunderbold controler of the CPU but a discrete Thunderbold controler, which seems to be the exact same one from that expansion card with the pci id of 8086:1137.

High level problem desciption: I have Thunderbold dock with DP-out, USB ports and an Ethernet port. When I plug it in, only the DP port works. When its plugged in before boot, ethernet also works. The USB ports on the Dock never work.

dmesg is showing several erros regarding DMAR and xhci, since the DMAR errors are shwing up first is suspect them to be the root cause making the rest afterwards fails also.

The error is slightly different between 5.13 and 5.14

5.14-rc7:

[    3.148557] DMAR: DRHD: handling fault status reg 2
[    3.148561] DMAR: [DMA Write NO_PASID] Request device [0x04:0x00.0] fault

addr 0x69974000 [fault reason 0x05] PTE Write access is not set

5.13.12:

[    3.737783] DMAR: DRHD: handling fault status reg 2
[    3.737790] DMAR: [DMA Write] Request device [04:00.0] PASID ffffffff fault

addr 69974000 [fault reason 05] PTE Write access is not set

04.00.0 is the thunderbold controller:
04:00.0 USB controller [0c03]: Intel Corporation Thunderbolt 4 NHI [Maple Ridge 4C 2020] [8086:1137] (prog-if 40 [USB4 Host Interface])

New info: The intel_iommu=off boot flag makes the DMAR errors go away. However xhci errors stay and the USB ports of the dock are still disfunctional. So they are seperate issues after all.

--- Comment #18 from Hans de Goede ([email protected]) --- Thank you for your bug report.

I've prepared a patch series fixing bug 206459 as well as this bug:

https://lore.kernel.org/linux-pci/[email protected]/T/#t

This series is using DMI matching to identify affected systems and to enable the workaround only on affected systems.

I've used DMI_MATCH(DMI_BOARD_NAME, "X170KM-G") as match for this Clevo Barebone.

Can you confirm that:

cat /sys/class/dmi/id/board_name

outputs "X170KM-G" ?

Or even better, give this patch series a try ? Note the series is based on top of:
https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/log/?h=pci/resource

Thank you for the patch.

Yes, "X170KM-G" is the exact match for /sys/class/dmi/id/board_name on the affected device.

Kernel with patch series is compiling atm. Will add another post wether or not it worked.

I have exactly the same Hardware and when I Enable my Discrete ThunderBolt in the BIOS, I experience a series of TimeOut delays during Boot.

I am running 5.15.53 on Slackware64 15.0 ...

I don't have a Dock for my LapTop so I am not sure this bug is a duplicate of
https://bugzilla.kernel.org/show_bug.cgi?id=206459

Q1: Is your Patch Series still viable ?

If so, your second link above for the patch series no longer works:
https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/log/?h=pci/resource

Q2: Was this patch ever included in the kernel source tree ?

If so, what version should I try ?

Thanks !

The series got merged in mainline:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/?qt=grep&q=Add+kernel+cmdline+options+to+use%2Fignore+E820+reserved+regions

the kernel.org cgit is always a good option to search if a patch got applied in the end

Also don't forget to check linux-next
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/log/?qt=grep&q=Add+kernel+cmdline+options+to+use%2Fignore+E820+reserved+regions

or subsystem specific branches like drm-tip (on the fredesktop cgit:

--- Comment #25 from Bjorn Helgaas ([email protected]) --- I don't know the connection to the DMAR faults, but from the first log
(https://bugzilla.kernel.org/attachment.cgi?id=298567):

BIOS-e820: [mem 0x000000006bc00000-0x00000000efffffff] reserved pci_bus 0000:00: root bus resource [mem 0x71000000-0xdfffffff window]

This entire PCI host bridge aperture is "reserved" in the E820 map, which means we won't allocate any PCI BARs in that area, which means hot-add won't work.

The current workaround for this is https://git.kernel.org/linus/d341838d776a
("x86/PCI: Disable E820 reserved region clipping via quirks"), which appeared in v5.19.

I think the underlying issue is that this machine has EFI, Linux converts the EFI memory map to E820 format, and it converts EFI_MEMORY_MAPPED_IO to E820_TYPE_RESERVED. EFI_MEMORY_MAPPED_IO means "the OS must map this memory for use by EFI runtime services." It does *not* mean "the OS can never use this memory." I think Linux should omit EFI_MEMORY_MAPPED_IO areas completely from the E820 map.

This is basically the same issue as bug #216565. I attached a patch there to omit EFI_MEMORY_MAPPED_IO.

I would love to hear from anybody with a Clevo machine that shows similar problems. If you can, please boot with the patch at
https://bugzilla.kernel.org/attachment.cgi?id=303123 with the "efi=debug" kernel parameter, open new bugzilla with the complete dmesg log, and assign it to me.

The referenced efi_mmio-2 Patch applied cleanly on 5.15.77 and I am building a 5.15.77_bjorn_p Kernel now.

I'll have to wait until after work to install and boot but I'll enable Discrete Thunderbolt in my Insyde EFI Bios and boot 5.15.bjorn_p

This dmesg for linux 5.15.77 without your Patch.

When I enable 'Discrete Thunderbolt' in the Insyde BIOS there is a long delay for each of the three DMAR Errors and a final delay for Thunderbolt ( see time

This is 5.15.77 with your patch applied

This is linux 5.15.77 with your patch applied.

There are extra log entries before event 'do_add_efi_memmap' at timestamp

[0.000000]

The same three DMAR faults and timeouts still happen between timestamps

[26.938364] and [88.372760] and there is still a Discrete Thunderbold error at

--- Comment #31 from Bjorn Helgaas ([email protected]) --- Thank you very much for all this work, Konrad!

I'm confused. Comments #16 and #17 suggest that this DMAR issue was fixed by
https://git.kernel.org/linus/d341838d776a ("x86/PCI: Disable E820 reserved region clipping via quirks"), which appeared in v5.19. Can you confirm that?

You're welcome.

I was unable to successfully apply those patches against 5.15.y and then I believe the patches were reverted or partially reverted in 5.19.y.

I will consider running a newer Long-Term Kernel when it is announced next month, especially if it fixes Discrete Thunderbolt and especially since 5.15.y will go EoL in Oct 2023.

Thanks for all you do for the Linux Kernel, Bjorn !

I think the long delay is a different issue then the e820 region patch and has more to do with this:

[   88.372827] thunderbolt 0000:07:00.0: failed to send driver ready to ICM

the 20s delay between the 4 retries come from this:

https://elixir.bootlin.com/linux/latest/source/drivers/thunderbolt/icm.c#L1024

or this

https://elixir.bootlin.com/linux/latest/source/drivers/thunderbolt/icm.c#L1630

respecifly.

Having the icm not correctly initialized seems to be no problem however? I read somewhere that there is a software fallback for it. But I don't really know what the icm actually does in the first place xD.

--- Comment #36 from Konrad J Hambrick ([email protected]) --- Thanks for all the info [email protected]

The comments in Hans de Goede's three patches look familiar but I'll try all three patches against 5.15.y again.

Or should I be running a different Kernel Version ?

The Code referenced at elixir.bootlin.com is from Kernel Version 6.0.7 ...

I'll test next weekend when I've got time to build ; boot ; dmesg ; repeat

Then I will open a new bug report.

Thank you and thank you and Tuxedo Computers for the tuxedo-keyboard-master and tuxedo-keyboard-ite kernel modules ( they work great for me ) !

--- Comment #37 from Bjorn Helgaas ([email protected]) --- Regarding the delay, i.e., this from Konrad's attachment at comment 27:

[    6.837625] DMAR: DRHD: handling fault status reg 2
[    6.837629] DMAR: [DMA Write NO_PASID] Request device [07:00.0] fault addr

[   88.380241] thunderbolt: probe of 0000:07:00.0 failed with error -110

This all involves the same device (07:00.0) and it's all likely related, so I think we should reserve *this* bug report for this DMAR/timeout issue.

As far as I can tell, this is unrelated to bug 206459 and the E820 issues addressed by Hans de Goede's patches, so I'm going to reopen this bug report.

If we're lucky, maybe the DMAR/timeout stuff has been fixed by something between v5.15 and v6.0.

lspci -vvv for my Sager NP9672M / Clevo X170KM-G

Thanks Bjorn

Attached is lspci -vvv on the unpatched 5.15.77 Kernel if it helps.

It is large-ish but more may be better than less.

Should I try Linux 6.0.7 or maybe even 6.1.rc3 ?

Just tested 6.1-rc4 (from ubuntu mainline ppa)

Still same behaviour: 4*20s delay during boot, but works just fine afterwards.
