[REQUEST] AMD Athlon 64 X2 3250e on Asus M4A78L-M LE

Edit: Yes I believe I can patch it.

Try to boot 3250e on supported motherboard and dump SSDT from it. Then inject SSDT into your system.

Don't have a motherboard here which supports it, would have to purchase one (which kind of defeats the purpose). Was kind of hoping that it would be possible to alter the bios to return the pss for the 3250e so the linux kernel would initiate the powernow_k8 driver.

Is it an good idea to alter an SSDT from another processor?

I have not found a way yet.

It's good idea. But you need suitable values for _PSS.

Decided to drop it for now. My brother needs a PC so I'm pairing it with a Phenom 2 I have and giving it to him. There is a Foxconn A7GMS 2.0 that I might use it for it which would probably have the same issues (as well as huge issues with AHCI).

Anyway thanks for the insight I might look in to using a script to inject SSDT values. If I finish that I'll post it somewhere here.

A small number of states - this is my guess why the table is not created, after analyze code at 0x5B483(57B4h:3943h).

Thx! Nice results!

Can Linux replace or patch SSDT when it starts?
Have you a hardware programmer to recover?

It's possible but the methods are not maintained far as I know. So I don't know what issues might arise on newer kernels.

And no I don't have a hardware programmer.

Hi, just to say it was working for me.
I was able to copy SSDT table from a working config with Opteron180, from one MB to another and enable powernow_k8.
You can do this with grub, in grub.cfg add "acpi /ssdt.aml" and put ssdt.aml in /boot
The .aml was generated with iasl tool, I'm not sure if we can directly use extracted table.
