Dear all,
after a while using Jailhouse on 4.09 on TX1, I came back to the stock
Nvidia kernel since (as far as I've understood) X is not yet fully
supported when using the free GPU driver, and I'd like to setup a
demonstrator with graphics over Jailhouse.
When enabling Jailhouse on the 3.10 kernel I've got these errors on dmesg.
Jailhouse didn't print any error message on the serial console.
The system seems fully functional most of the times, even using X (the
system crashed only once)
I've progressively increased the address spaces for the root cell in the
hope of resolving the possible conflict, but without success (the root cell
now has access to almost the whole address space).
Can you help me in figuring out what this problem could be related to ?
Many thanks and best regards,
Claudio
