[Bug 1884232] Re: touchpad doesn't work at all on ACER Spin 5
It seems we got stuck here, I've done everything I was asked for, now we
need somebody kernel-competent to review what I've posted and... let's
hope it will not take too long. If anybody else is affected, please mark
so at the top ("this affects me too") - to give this bug more heat
points. Thanks a lot to everyone involved!

[Bug 1884232] Re: touchpad doesn't work at all on ACER Spin 5
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
(0xfe01).
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
0xfe01-0xfe010fff]"). Apparently we declined to use that BIOS
assignment because it "conflicts with Reserved [mem
0xfc80-0xfe7f]". Perhaps Linux should ignore that conflict.
That "Reserved [mem 0xfc80-0xfe7f]" comes from the E820 map, and
the Linux handling of that map is somewhat haphazard.

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.

[Bug 1884232] Re: touchpad doesn't work at all on ACER Spin 5
This looks like a BIOS defect. BIOS programmed BAR 0 to [mem 0xfe01-0xfe010fff], but according to the PCI0 _CRS method, that area is not routed to the PCI bus: ACPI: PCI Root Bridge [PCI0] (domain [bus 00-fe]) pci_bus :00: root bus resource [mem 0x000a-0x000b window] pci_bus :00: root bus resource [mem 0x3f80-0xbfff window] pci :00:1f.5: [8086:34a4] type 00 class 0x0c8000 pci :00:1f.5: reg 0x10: [mem 0xfe01-0xfe010fff] pci :00:1f.5: can't claim BAR 0 [mem 0xfe01-0xfe010fff]: no compatible bridge window pci :00:1f.5: BAR 0: no space for [mem size 0x1000] pci :00:1f.5: BAR 0: trying firmware assignment [mem 0xfe01-0xfe010fff] pci :00:1f.5: BAR 0: [mem 0xfe01-0xfe010fff] conflicts with Reserved [mem 0xfc80-0xfe7f] pci :00:1f.5: BAR 0: failed to assign [mem size 0x1000] 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). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1884232 Title: touchpad doesn't work at all on ACER Spin 5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1884232/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

OK, I've successfully installed Ubuntu. Made successfully apt update && upgrade.

[Bug 1884232] Re: touchpad doesn't work at all on ACER Spin 5
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?
