I've tried adding these kernel parameters in GRUB before boot placing them just between the "splash" and "---":

i8042.nopnp=1 pci=nocrs

(according to here https://www.reddit.com/r/linuxquestions/comments/f9h0q4/touchpad_issue_lenovo_s14515iil/fmg277m/ )

And voila!
- Touchpad is working
- Touchscreen is working
- pen/Stylus is NOT working properly - it behaves only just like if using a finger - no additional functionality except for basic "clicking"

BUT! according to kernel documentation ( https://www.kernel.org/doc/html/v4.10/admin-guide/kernel-parameters.html ) - this is a BUG and shall be reported:

nocrs [X86] Ignore PCI host bridge windows from ACPI.
If you need to use this, please report a bug.

So... what are next steps, please?

Thanks

This looks like a BIOS defect. BIOS programmed BAR 0 to [mem 0xfe010000-0xfe010fff], but according to the PCI0 _CRS method, that area is not routed to the PCI bus:

  ACPI: PCI Root Bridge [PCI0] (domain 0000 [bus 00-fe])

Can you check to see whether a BIOS update is available?

Can you please attach the contents of /proc/iomem (I think you have to save the contents as root in order to see the values).

But once there is a consensus it's a BIOS bug, I will communicate it with ACER to have it fixed (I hope).

Anyone has seen a similar error already?

It looks like a BIOS bug to me.

But Windows does work, and Linux should, too. It looks like there's plenty of available space for 00:1f.5 BAR 0. Can you try a current version of Linux, e.g., v5.8-rc1 with the command line argument 'dyndbg="file drivers/pci/* +p"'? There were some significant resource assignment changes in v5.5.

AIDA64 (https://www.aida64.com/) has a free trial version that should show the PCI address map under Windows. I assume it probably moved 00:1f.5 BAR 0 to somewhere inside the PCI host bridge window.

Thank you Bjorn,

1) do you suggest building my own kernel locally according to here https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel or do you have any specific kernel to use (like from PPA ?

2) I will get AIDA info for you, meanwhile, I'm already having this output from hwinfo64 windows app (attached) - maybe it helps already (?)

many thanks, really appreciate your help!

1) Sorry, I don't have a PPA or similar kernel image for you to try.

2) I expected that Windows would move 00:1f.5 BAR 0 to be inside the windows reported by the PCI0 _CRS, but the AIDA64 report shows otherwise:

B00 D1F F05: Intel Ice Point-LP PCH - SPI (Flash) Controller

Offset 000: 86 80 A4 34 06 04 00 00 30 00 80 0C 00 00 00 00
Offset 010: 00 00 01 FE 00 00 00 00 00 00 00 00 00 00 00 00

BAR 0 is at offset 0x10, and it still contains the value BIOS put there (0xfe010000).

I don't know why Linux couldn't find space for 00:1f.5 BAR 0. Tracing the resource assignment code with 'dyndbg="file drivers/pci/* +p"' and possibly some new trace messages might give a clue.

When Linux fails to assign space, it tries to revert to the BIOS assignment ("BAR 0: trying firmware assignment [mem 0xfe010000-0xfe010fff]"). Apparently we declined to use that BIOS assignment because it "conflicts with Reserved [mem 0xfc800000-0xfe7fffff]". Perhaps Linux should ignore that conflict.

That "Reserved [mem 0xfc800000-0xfe7fffff]" comes from the E820 map, and the Linux handling of that map is somewhat haphazard.

Hi @Bjorn,

is this the right kernel to test on?
https://code.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/unstable/+ref/master-5.8

I'm just git-cloning it..

Once compiled and set, you need me to boot with 'quiet splash dyndbg="file drivers/pci/* +p"' instead of current 'quiet splash i8042.nopnp=1 pci=nocrs' in GRUB and send dmesg output again? Is that correct?

Thank you

Bjorn Helgaas (bjorn-helgaas) wrote on 2020-07-02:

Yes, I think that kernel is fine.

You can leave the i8042.nopnp=1 in your kernel command line parameters. Otherwise it looks right.

I've just found out there is no need to compile kernel myself in Ubuntu, because this distro provides upstream kernel packages according to this: https://wiki.ubuntu.com/Kernel/MainlineBuilds

So... I'm just downloading from here:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8-rc4/

Namely these three:
- https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8-rc4/amd64/linux-headers-5.8.0-050800-generic_5.8.0-050800.202007052030_amd64.deb
- https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8-rc4/amd64/linux-image-unsigned-5.8.0-050800-generic_5.8.0-050800.202007052030_amd64.deb
- https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8-rc4/amd64/linux-modules-5.8.0-050800-generic_5.8.0-050800.202007052030_amd64.deb

Two questions:
1) Is that three .deb s enough or do I need also _all?
( https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8-rc4/amd64/linux-headers-5.8.0-050800_5.8.0-050800.202007052030_all.deb )

2) Is this procedure OK and valid for your purposes?

Thank you for the workaround! With the latest Ubuntu this works with just the "pci=nocrs" parameter. The pen input works fully in Wayland, but not at all in X11.

Also, I wrote an installation guide for this laptop with more fixes and tips:

This workaround (pci=nocrs) sorted my Touchpad issues on a Clevo NL51LU; it wasn't being detected due to the 'resource claim' issue at boot, as above.
See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1904052.

Incidentally, I tried kernels up to 5.10.0 and same problem.

Sorry that it is taking so long to fix this. There have been several attempts at fixing this upstream already, but all of them had to be reverted/dropped because they were causing issues on other laptop models.

The latest attempt at fixing this is here:
https://<email address hidden>/

And this patch, or something close to it will hopefully go upstream soon.

Perhaps one of the Ubuntu kernel devs can provide a test kernel with this patch for Ubuntu users with this problem to test?

Thanks for informing us, Bjorn. That means the safest way to go is wait until one's favourite distro ships kernel 5.19, which requires 5.19 be oficially out (non-rc stable final) - any estimates how long this might be (how much time kernel updates usually need to get from RC1 to final release?)

AceLan, I have tested your kernel and touchscreen and touchpad work, without the pci=nocrs GRUB option. Thank you very much!

I have two pieces of feedback on it that I think are specific to my system, but I want to log them in case they aren't. After selecting the patched 5.15 kernel in GRUB, I get the following message for a few seconds before the kernel starts to boot:

"error: null src bitmap in grub_video_bitmap_create_scaled.
Loading Linux 5.15.0-1043-generic ...
Loading initial ramdisk ...

Press any key to continue...."

I believe this is due to my custom GRUB theme, but it wasn't occurring on the 5.19 kernel. On both the 5.19 kernel and the 5.15.0-1043 kernel, booting is very slow - the kernel boot messages seem to take much longer than the stock 5.15 kernel. I assume this is for debugging purposes, but wanted to call it out just in case it's unexpected behavior. I'm more than happy to trade a slower boot for a working device of course! Again, feel free to ignore these quirks if they are specific to my system/expected behavior, I'm just being overly-thorough at this point.

Thank you for backporting this!

I don't know what's in the 5.18.10-76051810-generic kernel (I assume that's v5.18 + some Ubuntu patches). The upstream fixes for this went into v5.19: https://git.kernel.org/linus/3cc30140dbe2
I think v5.18 + the following patches (which somebody added in the "Bug Description" at the very beginning of this report) should work:

crysman,

The patch lists the affected platforms that have been reported with the issue. If the test kernel doesn't work for you(but pci=nocrs works), please post the output of 'sudo dmidecode --type 1' here, so that we can add the affected platform to the list.

Well, @acelankao, I am the one who created this bugreport originally, so my platform is certaily affected and I had already posted any info needed.

As @bjorn-helgaas writes, it seems to be fixed in 5.19, I just got confused by #48 and #49 stating it works in 5.15, but I missed the part with custom kernel, my bad, sorry.

=> I will wait for 5.19, thanks everyone for fixing this - it's been a looong journey though - I posted this two years ago... Nevertheless, better late than never, thanks again :)

It's booting fine indeed with the regular Ubuntu kernel (5.15.0-47-generic here) but I have many error messages like:

that are not present in mainline kernels (5.19.0-051900-generic for instance).

experimental patch to remove EfiMemoryMappedIO Edit (1.3 KiB, text/plain)

This is likely a duplicate of https://bugs.launchpad.net/bugs/1878279

The current upstream resolution to this problem is https://git.kernel.org/linus/d341838d776a ("x86/PCI: Disable E820 reserved region clipping via quirks"), which relies on quirks that match DMI Vendor, Product Version, Product Name, and Board Name. This isn't an ideal solution because there are likely other systems we don't know about that need a similar fix.

The patch I'm attaching here is an experimental idea to work around this issue without the maintenance burden of the quirks.

If anybody would be willing to test this patch, I would be very grateful. To test it, apply this patch to your kernel, boot with "pci=use_e820 efi=debug", and collect the dmesg log.

Hello, since I do not like the idea of maintaining quirks neither, I could help you, but the problem is I'm very busy lately - if you could describe (or provide link to) more detailed howto, I would test it. I just cannot spend extra time figuring-out the details... I've become more of a "just user" of my computer rather than former "hack-the-best-out-of-it kinda' geek", sorry...

No worries, your report and testing so far has been an immense help, so thank you for that!

https://git.kernel.org/linus/07eab0901ede ("efi/x86: Remove EfiMemoryMappedIO from E820 map") is essentially the same as the test patch from comment #62, and it appeared in v6.2-rc1, so just wait for a kernel image that includes that.

It turned out that 07eab0901ede broke extended config space on some systems, so there's a fix for that (https://git.kernel.org/cgit/linux/kernel/git/helgaas/pci.git/commit/?id=ac729baefdc3) that should appear in v6.2-rc4.
