Hi Rlf，
Thank you for your reply. I solved the issue based on your suggestions.
However, I've encountered another problem. As shown in the image below,
I found that the MSI Capabilities of a PCIe device are being read
incorrectly as '0xff'. When I don't enable the Root Cell, the readings
with setpci are normal. However, when the Root Cell is enabled, the

Please describe your issue in a temporal flow.

What means the device hangs? Does Jailhouse crash?
msi_registers.raw is abnormal. I have verified that mmcfg_addr is
correct, but the read values are still incorrect. How should I proceed
with further debugging?
Would you please share (as text attachments):
- lspci -vvv (before enabling jailhouse)
- jailhouse-config-collect yoursystem.tar
- Jailhouse System Configuration as C Source
Why are you trying to change in PCI config space, what are you writing,
and what would you expect?
The device should not hang and there should be no need for you to modify
config space after enabling jailhouse, the device should continue
working as before.
Thanks,
Ralf

would you please disassemble your hypervisor binary with objdump, and
see what routine executed behind 0xfffffffff000b250?
