meta-agl-jailhouse: Add support for RPi4 with 2G/4G/8G of memoryjellyfish_9.99.3jellyfish/9.99.39.99.3
The Jailhouse configuration files had to be modified to append the additional
memory regions present on the higher mem variants of the RPi4.
To avoid the use of mem= kernel parameter to fix the memory that can be used
by the root cell, a device tree overlay with reserved-memory nodes is used
instead.
To avoid conflict with the GPU memory, the memory region used for Jailhouse
and the non-root cells was moved from 0x30000000 to 0x20000000.

The other ones will work too, - but will be limited to 1 GB of memory. + * All (1G-8G) memory variants. But note that there is 256M reserved for Jailhouse and 256MiB for GPU in AGL, so the smaller variants are not recommended. * QEMU x86-64 * Work in progress. Requires KVM. Nested virtualization must be enabled on the host. Currently, the right configuration of QEMU and Jailhouse to work out-of-box is being worked on. |
