Hello everyone,
Lately i've tried to configure the recent Ultra96 cells to use IVHSMEM memory
region between them. I can enable the root cell (ultra96-ivshmem.cell) but when
I try to create the non-root cell (ultra96-gic-demo-ivshmem.cell), the system
freezes and i can't input any character to console.
Here is the output after inputing "jailhouse cell create
ultra96-gic-demo-ivshmem.cell":
[ 80.464769] CPU3: shutdown
[ 80.467397] psci: CPU3 killed.

There is no physical RAM at 0x80000000 and above. Chose a region from the
reservation (>= 0x60000000).
.virt_start = 0x80001000,
.size = 0x100000,
.flags = JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE |
JAILHOUSE_MEM_ROOTSHARED,
