Hmm, this fails when passing it to jailhouse config create. Could it be that you
ran the collect job as normal user, not as root?
Seems like I failed to copy it from the remote host via scp.
I have attached a new version.
It has been run with current working condition.
I ran into more problem.
This card have BAR1 32bit presenting a MMIO address for its 16550 registers.
Mapping and accessing it in the Linux driver is OK.
However, the whole page is presented as 0xff and writing has no effect in a
custom RTOS cell.
I passed this device into a custom RTOS cell by adding PCI device, PCI caps,
and memory regions in the config file.
My code had mapped the BAR1 physical address 1:1 to virtual space.
Have I done anything wrong?
You possibly lack some logic in your RTOS code to properly enable the PCI
device, like Henning mentioned. You can always validate that by booting a Linux
in the non-root cell - it comes with all the needed logic.
