Subject: Need help to debug ata errors
Date: Fri, 3 Dec 2021 11:11:53 +0000 [thread overview]
Message-ID: <df61e958-7bd6-94df-0da2-56aa1084350d@xilinx.com> (raw)
Hi All,
I am trying to run linux as a DomU guest on Xen with AHCI assigned to it.
I can confirm that SATA works (ie able to detect sdb) as a Dom0 guest.
However, it does not work as a DomU guest.
Hardware :- ZCU102 board and it has two sata ports
Kernel :- 5.10
I have enabled the debug logs in drivers/ata
1. Logs from dom0 (where SATA works) https://pastebin.com/2BhMDq47
2. Logs from domU (where SATA does not work) https://pastebin.com/fE8WZnZ0
Can some help me to answer these questions
1. What does this mean "1st FIS failed" ?
2. In the dom0 logs, PORT_SCR_ERR = 0x41d0002 whereas in domU logs,
PORT_SCR_ERR = 0. Does it give some hints ?
3. Any other issues or hints to debug this ?
I can confirm that in domU scenario, we do not get any interrupts from
the device. What might be going wrong here ?
Thanks in advance.
Kind regards,
Ayan
