After updating my memory layout, i.e. after creating one region for
loading the linux another for DDR RAM and lastly the communication
region in my inmate I no longer see the unhandled read error.
/* linux-loader space */ {
.phys_start = 0x59000000,
.virt_start = 0x0,
.size = 0x6400000,
.flags = JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE |
JAILHOUSE_MEM_EXECUTE | JAILHOUSE_MEM_LOADABLE,
},
/* RAM */ {
.phys_start = 0x5F400000,
.virt_start = 0x5F400000,
.size = 0x19C00000,
.flags = JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE |
JAILHOUSE_MEM_EXECUTE | JAILHOUSE_MEM_DMA |
JAILHOUSE_MEM_LOADABLE,
},
/* communication region */ {
.virt_start = 0x80000000,
.size = 0x00001000,
.flags = JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE |
JAILHOUSE_MEM_COMM_REGION,
},
I am able to load the linux on one of the CPUs but I cannot see any
console output on the serial.

Any pointers on debugging this? (jailhouse cell stat 1 doesn't seem to
updating the number so I assume it's panicked somewhere)
