ASMEDIA SATA Controller Woes - 1164 Works, 1166 and 1064 Do Not

[Seed]

I have 3 ASMEDIA controlls.

1164 on a DXP8800
1166 as a 6 port PCIe card
1064 onboard a CWWK motherboard

When I was on PVE 9.0 the DXP8800 wouldn't pass through the second controller. After updating to 9.2, this was fixed and looking at some discussions here looks like a "quirk" or something was introduced to fix this in the kernel, specifically for this NAS model and the 1164 controller.

On my CWWK board I have an onboard controller along with 2 Intel controllers. The intel one passes through fine, and so does the ASMEDIA one as far as I can tell. But when I look at the VM be it Truenas or Ubuntu 26.04 the card isn't there.

I then tried a PCIe card I had around which is the 1166 version controller and while it seems I can pass this through to the VMs it simply doesn't show up in the VM then obviously the drives attached do it don't either.

Any ideas? I am looking to compile a custom kernel but get some github auth issues to the kernel-mirror repo so it's not available to build against.

Probably a firmware and/or hardware issue with the ASM1166. Someone else also recently complained, here:

Maybe you are better at reading, than the other guy.

How does that help me? Ive read your posts and they are incomplete and dont reference my issue directly...

If you would've shown any kind of details of your issue, other than "...it simply doesn't show up in the VM..." then maybe someone might be able to help.
Questioning the helpfulness of others, however is certainly the way to go, if you provide no information.

The controller doesn't show up in the VM when it's passed through. i dont know what other information to provide, lmao...

So clearly ive used the "search function"....
