I'm trying to run jailhouse on Jetson tx2 kit. I downloaded the jailhouse
and compiled it and run the command
=>sudo insmod Downloads/linux-jailhouse-jetson/driver/jailhouse.ko
// there is no error message in terminal console
but it gives following output on the serial console:
tx2@tx2-desktop:~$ [ 129.954491] jailhouse: loading out-of-tree module
taints kernel.
After this I tried to enable jailhouse through this command
=>sudo jailhouse enable Downloads/linux-jetson/configs/arm64/jetson-tx2.cell
// terminal displays: JAILHOUSE_ENABLE: Invalid argument
//and on the terminal console it displays:
[ 333.421533] jailhouse: mem_region_request failed for hypervisor memory
mem_region_request failed for hypervisor memory mem_region_request failed
for hypervisor memory mem_region_request failed for hypervisor memory.
[ 333.428303] jailhouse: Did you reserve the memory with "memmap=" or
"mem="?
I have changed /boot/extlinux/extlinux.conf file as follows:
TIMEOUT 30
DEFAULT primary
MENU TITLE L4T boot options
LABEL primary
MENU LABEL primary kernel
LINUX /boot/Image
INITRD /boot/initrd
APPEND ${cbootargs} quiet
*mem=7808M vmalloc=512M*
# When testing a custom kernel, it is recommended that you create a backup
of
# the original kernel and add a new entry to this file so that the device
can
# fallback to the original kernel. To do this:
#
# 1, Make a backup of the original kernel
# sudo cp /boot/Image /boot/Image.backup
#
# 2, Copy your custom kernel into /boot/Image
#
# 3, Uncomment below menu setting lines for the original kernel
#
# 4, Reboot
# LABEL backup
# MENU LABEL backup kernel
# LINUX /boot/Image.backup
# INITRD /boot/initrd
# APPEND ${cbootargs}
but this change is not working. So what's the wrong in this extlinux.conf
file as boot up is ignoring *mem=7808M vmalloc=512M *this statement.
Please help me through this error.
Thank you
