Greeting All,

I have an AMD Epyc 7282, on supermicro H11SSL-i, I want passthrough 1 SATA controller to my VM (TrueNas).But I get the error from my VM:

I have see some thread: like `https://forum.proxmox.com/threads/trying-to-pass-through-a-sata-controller-on-the-motherboard.99192/`

I tried set the cofig:

I skip this error by a LSI IT card, but i want to know how fix it.

Is there anything else I can do?

Thanks!
 
limiting SATA link speed to is usually an indication of a bad cable or a connection not making good contact. Do you have those messages on the Proxmox VM with the same drives also?
Or maybe the SATA controller just doesn't work with passthrough or does not reset properly. That last issue can sometimes be worked around by making sure no driver touches the controller before starting the VM: blacklisting the driver or early binding the device to vfio-pci. Note that other controllers might have the same ID and/or driver, which would make them unusable for the Proxmox host. Usually a reset issue will also prevent you from starting the VM a second time without rebooting the Proxmox host.
 
1. all driver, cable run well in PVE，i think the pointor is "softreset failed ", if i got that error, I can not read in pve after host reboot.if i shutdown and power on, everything ok.
2. vfio for sata device already bind , i wrote the conf:softdep ahci pre: vfio-pci, this config from your other thread, the driver for sata controller -> vfio-pci, but still softreset failed.
3. "maybe the SATA controller just doesn't work with passthrough" , how can i confirm that? ask for supermicro?

Look for a post on the internet from someone else who got that specific controller working with passthrough, and find out how they did it. (I assume devices don't work with passthrough until someone reports that they got it working.)
With kernel 5.15, you can select the reset method (and even disable it) according to some documentation about /sys/bus/pci/devices/.../reset_method. Maybe using another reset method works for you?
Virtually disconnecting the device from the PCIe bus (echo 1 >/sys/bus/pci/devices/0000\:44\:00.0/remove) and then rescanning the PCIe bus (echo 1 >/sys/bus/pci/rescan) works for some devices.

Thans U.
maybe i can try the reset_method.:)

Look for a post on the internet from someone else who got that specific controller working with passthrough, and find out how they did it. (I assume devices don't work with passthrough until someone reports that they got it working.)
With kernel 5.15, you can select the reset method (and even disable it) according to some documentation about /sys/bus/pci/devices/.../reset_method. Maybe using another reset method works for you?
Virtually disconnecting the device from the PCIe bus (echo 1 >/sys/bus/pci/devices/0000\:44\:00.0/remove) and then rescanning the PCIe bus (echo 1 >/sys/bus/pci/rescan) works for some devices.

ohhhhhhhhh,than u, it worked by set "bus" reset_method.
Bash: 
echo "bus" > /sys/bus/pci/devices/0000:44:00.0/reset_method

I am about to get the exact same system.

Does the sata controller passthrough work for you now?

Did I understand that right that you just "changed" the reset method "permanently" by once executing
Code: 
echo "bus" > /sys/bus/pci/devices/0000:44:00.0/reset_method
where 0000:44:00.0 is your controller?

Does that survive a reboot?
Did you exclude the controler somewhere else as well to in PVE ensure that it gets passed through to the VM?
