Thanks for the pointer that did the trick. I am now able to ping from
root/inmate and vice versa.
* For the Linux (root/inmate) IVSHMEM what is the test case that needs
to be run? (Ive done devmem read/write on root & inamte cell)
* I updated to the latest tip of next and now I am seeing below issue:
** Previously "jailhouse config check -a arm64
renesas-r8a774a1.cell" worked, now when I run "jailhouse config check
renesas-r8a774a1.cell" I get the below output:
root@hihope-rzg2m:~# jailhouse config check renesas-r8a774a1.cell
Reading configuration set:
Architecture: x86
Root cell: Renesas HopeRun HiHope RZ/G2M (renesas-r8a774a1.cell)
Overlapping memory regions inside cell: None
Overlapping memory regions with hypervisor: None
Missing PCI MMCONFIG interceptions: None
Missing resource interceptions for architecture x86: None
^^ Architecture detected here is x86 which isnt correct.
* Previously "jailhouse enable renesas-r8a774a1.cell" worked but
after update I am getting below error:
jailhouse: Configuration architecture mismatch
JAILHOUSE_ENABLE: Invalid argumen
Cheers,
