ACPI Patch Error

[vrolife]

The ACPI patch needs to be port to TM2119, please provide the ACPI tables generated by acpidump -b.

[MalpenZibo]

Maybe it's caused by my tentative to install the acpi path changing the TM2107-Redmi_Book_Pro_14_2022 to make it work (with no luck) on my laptop but right now the acpidump -b command returns:

Table signature (0x4F324824) is invalid
Could not get ACPI table at index 34, AE_BAD_HEADER

I already launched the uninstall.sh acpi script to revert my tentative.

In any case, right now everything seems to work ok with the exception of the fingerprint sensor (I tried with the docker driver that work only for the first scan and after that the service crashed) and the internal microphone.

[MalpenZibo]

Same result on a fresh arch linux installation

Table signature (0x4F324824) is invalid
Could not get ACPI table at index 34, AE_BAD_HEADER

Here is another way to dump ACPI table sudo cp /sys/firmware/acpi/tables/DSDT ./dsdt.dat.

Here's a link to the dsdt.dat file https://drive.google.com/file/d/1nmx7xwiJRHZYG7OWSiXQQT0Z-Dusx7gE/view?usp=share_link

Need to know the BIOS version. dmidecode -t bios |grep Version

[MalpenZibo]

BIOS version: XMARB4B0P0B0B

[vrolife]

Try this branch. https://github.com/vrolife/modern_laptop/tree/TM2119

Thank you so much, you're a hero!!

I tried (I have systemd-boot).
NO_GRUB=1 sudo ./install.sh acpi and then I add to /boot/loader/entries/my_entry.conf

initrd  /acpi_override
options ... acpi_osi=! acpi_osi=Linux

After a reboot, the internal microphone still doesn't work

[MalpenZibo]

I notice that with the patch is not possible to set the screen brightness. Right now I removed the changes to the /boot/loader/entries/my_entry.conf file and the brightness can be changed again.

[vrolife]

Could it be "initrd /boot/acpi_override"? I know nothing about systemd-boot.

[vrolife]

Secure Boot will prevent Linux from loading ACPI patches, you may need to disable Secure Boot.

[MalpenZibo]

Secure boot Is already disabled.

Now I tried with /boot/acpi_override but the system doesn't start anymore (I've to fix It)
The error is: "Error preparing initrd: Not found"

[MalpenZibo]

Anyway, misconfig is fixed.
I think that the correct configuration is /acpi_override and something changes if I set that parameter (screen brightness cannot be changed anymore).

[vrolife]

Check whether ACPI table is correctly overwritten sudo dmesg|grep -i acpi|grep -i override

[MalpenZibo]

Ok! I can confirm that the patch is applied and the internal microphone now works. The only downside is that the screen brightness cannot be changed, without the patch the screen brightness can be changed but the internal microphone doesn't work.

sudo dmesg|grep -i acpi|grep -i override output

system-boot entries:

title Arch Linux acpi override (linux)
linux /vmlinuz-linux
initrd /acpi_override # it seems important to place the `/acpi_override` option before the other initrd
initrd /amd-ucode.img
initrd /initramfs-linux.img
options ... acpi_osi=! acpi_osi=Linux

[MalpenZibo]

Without adding options ... acpi_osi=! acpi_osi=Linux both internal microphone and screen brightness seems to work.

I'll test this setup to understand if cause other problems but for now it seems working well.

[vrolife]

acpi_osi=! acpi_osi=Linux fix that TM2113 cannot wake up without AC power. If your laptop doesn't have this problem, you may not need this option.

[MalpenZibo]

This problem seems not happen on this model.

Thank you so much. Now everything seems working correctly.

[MalpenZibo]

This solution stops working. I don't know why (probably some arch linux update) but right now if I try to boot the system using the entry with initrd /acpi_override I get a black screen and nothing more.

I'm currently booting the system without the acpi_override and with the internal microphone issue.

Do you have some ideas about this new problem?

[MalpenZibo]

Fixed with a bios rollback
