I solved this problem by trying some different memory configurations.
The following does work:
mem=448M vmalloc=256M
/* Orangepi0.c */
.hypervisor_memory = {
.phys_start = 0x5f800000,
.size = 0x800000,
},
...
/* RAM */ {
.phys_start = 0x40000000,
.virt_start = 0x40000000,
.size = 0x1f700000,
.flags = JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE |
JAILHOUSE_MEM_EXECUTE,
},
/* IVSHMEM shared memory region */ {
.phys_start = 0x5f700000,
.virt_start = 0x5f700000,
.size = 0x100000,
.flags = JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE,
},
--------
But if I use the following configuration. When I enable jailhouse, it says
"JAILHOUSE_ENABLE: Invalid argument".
/* orangepi0.c */
.hypervisor_memory = {
.phys_start = 0x5c000000,
.size = 0x4000000,
},
......
/* RAM */ {
.phys_start = 0x40000000,
.virt_start = 0x40000000,
.size = 0x1bf00000,
.flags = JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE |
JAILHOUSE_MEM_EXECUTE,
},
/* IVSHMEM shared memory region */ {
.phys_start = 0x5bf00000,
.virt_start = 0x5bf00000,
.size = 0x100000,
.flags = JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE,
},

I don't know what's wrong with the second cell configuration
Thanks!
