Screenshots from Win8.1 before and after installing I2C driver:

so your speakers (hardware ID) are from realtek, good to now, I already have a template for realtek backend but it's empty so far. I will try to implement it better when I have time
how does the log look like on XP?

Implemented support for some missing HW IDs.

Also included i2cctrl_helper.cpl.

Still no Realtek I2S device detected.

Do these drivers work and get the job done on your Asus laptop? Do they initialize devices connected via I2C?

It's even worse for my case... because I don't even know how to run acpi ssdt tables .aml from Clover to ensure that my controller is powered on.... (Windows OSI version limit thanks to firmware, it enables and disables values according to OSI)

use the SLIC tool to check what acpi tables XP does load for you and check for all informations of your device in the ACPI tables (if it's on a acpi table not loaded by XP, then that explains the issue too).

Until then, no ACPI I2C enumeration works for now (mostly my case, yours may just need correct MMIO mapping IDK), not even for me (unless I fake it by enumerating it directly from i2cctrl instead of ACPI, but that would be a fake/virtual device and not the real thing, i'd rather focus on the real device than a virtual device).

Keep in mind that this driver was intended to be used on XP (it's adjusted to what it can do on XP) and not on later versions (meaning that it's pure WDM, no KMDF dependency, no sbpcx, no acpiex)...

And if you ask why I use i2cctrl.log, it's obvious, this is the only hardware with I2C that I have (it doesn't have serial port, ethernet port for debugging). On crashes I debug the crash in windbg in win11 from xp's memory.dmp (on the same hardware), while outside of BSOD through i2cctrl.log.

My controller is I2C IO Cannon Lake based on LPSS, yours is I2C EC based on DW, so maybe the mechanism isn't even the same for you compared to me.

BAR0 is detected I see, unlike in my case.

That means that the detection code on my i2cctrl.sys driver is not broken, the firmware maybe enables and disables controllers (power state of the controllers) based on OSI!

If you want to get this to work, we are gonna need help improving the ACPI 2.0 from Mov0xDead to add support, because even if OSI would be correct, our current XP's ACPI 2.0 still doesn't understand this at all!

@Dietmar This is where you come in, do you want to help me adding I2C/GPIO/UART support in XP's ACPI 2.0 from mov0xdead? Even making sure that it reports as Windows 2015 (Windows 10) and above in the OSI if necessary. My driver has a lot of XP-friendly implementations (this means that no KMDF, no acpiex and no spbcx), it tries to use I2C in XP's language, it also has a lot of unused garbage code that it's just sitting there tbh.
