Hello. I would like to test eMMC with jailhouse hypervisor.
I installed a newly patched hypervisor on the Jetson tx1 board, But I had a
problem.
The settings for the internal memory area are as follows. IRQchips only set the
GIC for uarta.
I added mem=3648M vmalloc=512M to the kenrel.
.mem_regions = {
/* UART */ {
.phys_start = 0x70006000,
.virt_start = 0x70006000,
.size = 0x1000,
.flags = JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE |
JAILHOUSE_MEM_IO,
},
/* RAM */ {
.phys_start = 0x17bfe0000,
.virt_start = 0x0,
.size = 0x00010000,
.flags = JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE |
JAILHOUSE_MEM_EXECUTE | JAILHOUSE_MEM_LOADABLE,
},
/* inmate RAM */ {
.phys_start = 0x168000000,
.virt_start = 0x168000000,
.size = 0x10000000,
.flags = JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE |
JAILHOUSE_MEM_EXECUTE | JAILHOUSE_MEM_DMA |
JAILHOUSE_MEM_LOADABLE,
For the non root cell, I run the following command.
$LOAD_ADDR=0x169000000
$DTB_ADDR=0x170000000
$sudo jailhouse cell create jetson-test-a.cell
$sudo jailhouse cell load jetson-test-a inmates/tools/arm64/linux-loader.bin -a
0x0 Image -a $LOAD_ADDR inmate-jetson-tx1.dtb -a $DTB_ADDR -s
"kernel=$LOAD_ADDR dtb=$DTB_ADDR" -a 0x1000
$sudo jailhouse cell start jetson-test-a
I could see the output of stared cell "jetson-test-a" in the terminal window,
but the kernel did not boot.
In this case, do you think that the linux-loader provided by jailhouse does not
work properly?
Can I assume the settings are wrong?
I added mem=3648M to limit the memory area of the root cell. Should I add mem=
and vmalloc to the non root cell device tree for the non root cell?
