purpose your ACPI HID of your Wireless SOC
@tikilou, I have not read ALL of your previous posts. Did you explain how to do this in a way for people to understand how to do, who do not know as much as you about BIOS and Linux drivers?
I’ve forget that, sorry !
Dump ACPI Table :
sudo acpidump > acpi.dat(or take what you want in /sys/firmware/acpi/tables with root user)
Extract ACPI Table :
acpixtract -a acpi.datDecompile DSDT :
iasl -d dsdt.datIn dsdt.dsl (apparently we can found somes things in /sys/firmware/acpi/tables/SSDT* decompiled tables too and use them for correcting dsdt table, juste read it now), search the HID value for your hardware, compare with ACPID of the driver on Windows 10 with official drivers installed (proprierties), look if it use an existant compatible driver, and report it to the developer driver mainteneur of Linux modules kernel cibled.
Most of not working hardware on our tablets (Chuwi, Teclast, Onda, Dell…) have the same problem, ACPI Hardware IDs (HID) are not in database of existing drivers, so Linux Kernel who usually detect hardware with PCI IDs don’t know he can use an existant/compatible driver for them ! We need to report theses missing ACPI Hardware ID.I’m thinking it’s a problem with the i2c and SDIO controllers too.
For auto correcting and recompile dsdt.dsl to dsdt.aml (apparently it’s possible to manually correcting errors of ACPI DSDT table, and load it on Initramfs boot, i don’t know how to do that but all is here) :
iasl -tc dsdt.dslExample with the dsdt for chuwi Hi10 with DualOS bios dumped, extracted, decompiled : http://vavar60.online.fr/share/tablet/chuwi_hi10/Chuwi_hi10-DualOS-dsdt.dsl.txt
“OBDA” is the four letters for identify Realtek HID (Hardware ID) in DSDT part of ACPI table, after research i’ve found this for wifi sdio soc :

And now, he gonna purpose a new patch for support the Hi10 tablet with SDIO setting in bios configured to “ACPI”. 🙂
We have to do the same way for all hardware not actually supported, research, report, test. Then finally, later, Linux Kernel gonna include theses patchs.
I’m not a developer, and before have research for it, i’ve don’t know anything about ACPI table, so everybody can help about it. 🙂
Example with Bosch sensor for rotate screen, actually already supported by Linux kernel with “BOSCH bma2x2 accelerometer driver” project, but you can look inside the driver source code, there is not entry about ACPI HID : https://github.com/BoschSensortec/Linux_Kernel_Drivers/blob/master/drivers/input/misc/bma2x2.c
Ps : i’m giving the best now, but i’m in vacation now, i have a girlfriend, and we gonna travel around the world, wwoofing, etc, so i can’t be active like that anymore, but i’m sure this community, gonna work on all of that and fix theses problem soon. 😉
