      Re: Guest receiving passthrough SATA controllers does not see attached drives

      It seems i'm having the same issue, using an AMD Epyc 7313P with Asrock Rack ROMED6U-2L2T motherboard and also having problem with passthrough the Advanced Micro Devices, Inc. [AMD] FCH SATA Controllers.

      When I passthrough the PCIe ASM1166 card, can see and use the drives (that are connected to this card) within the VM.
      But when I passthrough the Advanced Micro Devices, Inc. [AMD] FCH SATA Controllers [AHCI mode], don't see any connected drives to these controllers.
      In the guest os (tested with Ubuntu and Truenas Core & Scale) i'm getting drive error.

      For example, this are a few errors i get in Truenas Core:

      
*root@truenas[~]# camcontrol reportluns 0:0:0

    subclass   = SATA

    vendor     = 'Advanced Micro Devices, Inc. [AMD]'
    device     = 'FCH SATA Controller [AHCI mode]'
    class      = mass storage
    subclass   = SATA
ahci1@pci0:70:0:0:      class=0x010601 rev=0x51 hdr=0x00 vendor=0x1022 device=0x7904 subvendor=0x1022 subdevice=0x7901

    device     = 'FCH SATA Controller [AHCI mode]'
    class      = mass storage
    subclass   = SATA*

      When passthrough is disabled, i can see and use the connected disks just fine within XCP-NG and then no errors are reported.

      Any thoughts?

        Hello @hvm,

        Can you give the output of xl dmesg in XCP-ng and of dmesg in the guest that has the issues ?
        I have the impression that something is going wrong with reserved regions related to the SATA controller.

          Hi @Teddy-Astie

          First of all, thanks for your thoughts!
          I'm pretty stuck with these issues. So hopefully other insights will help 🙂
          Below are the requested log files.

          xl_dmesg_passthrough_enabled-XCPNG_host.txt
          pci_devices-XCPNG_host.txt
          dmesg_VM-truenas_core.txt
          dmesg_VM-ubuntu_24_04.txt
          xl_dmesg_passthrough_disabled-XCPNG_host.txt

            Hello @Teddy-Astie

            Have you had the opportunity to review the log file output?

            The past few weeks I have spent a lot of time trying to find a solution. But unfortunately after all the things I have tried, none of them have solved or did changed something to the problem.

            We are investigating the possibilities to run our branch locations environments with XCP-NG. This requires a working PoC where passthrough of this SATA controller is necessary.
