Can you help develop the ata_piix module?

[PeterSuh-Q3]

Hello, @wjz304

pocopico is also a module that has been tried for a long time, but has not been successful yet. This is an essential module that enables SATA devices to operate on ICH5/6/7/8 controllers of older motherboards using LGA775. Modules that existed in the past Jun's loader or Redpill versions have not yet been developed. It seems to be related to syno libata, but I can't find the exact problem. The module associated with syno libata is sata_nv (module already developed by pocopico) and sata_sil and more.

The compiled module source is located in the path below.

https://github.com/PeterSuh-Q3/arpl-modules/tree/main/src/4.x/drivers/ata

The ata_piix module is already included in the integrated module, Even the module that was compiled again separately continues to receive the unknown symbol message. Again, what dependencies are there?

Attached is the log monitored by Junior. can you help me?

I don't have much research on drivers,

From the perspective of symbols, it seems that symbol names are related to some definitions of toolchain, and it may be necessary to modify the source code to make it compatible,

Additionally, I don't seem to have found the 'libata' that ata_piix relies on?

[PeterSuh-Q3]

Perhaps so it is speculated.

It also seems like a difficult task. I guess I'll have to spend some time researching it. It would be nice if it could be solved someday. There were users who demanded the necessity of this old chipset module.

Thank you for thinking about it together.
