Dear all,
I am trying to write configuration files for the root and
the non-root cells for an arm64 based system. I have checked the video
https://youtu.be/7fiJbwmhnRw and also the pdf. I could just infer from
these that I have to write the config files using the already existing
ones eg: amd-seatle.c and other files. But what I am not able to
understand is how do I come up with the different values in the config
files as in other files.
For Example:
This is small portion of amd-seattle.c how do we come up with the values
in the mem_regions[] as 20, irqchips[] as 3, hypervisor_memory.
phys_start = 0x83e0000000, and all othe r values in the config files.
Which document has been used. Any pointer to any of the documents of the
various config files listed in the configs would be a lot helpful.
#include <jailhouse/types.h>
#include <jailhouse/cell-config.h>
struct {
struct jailhouse_system header;
__u64 cpus[1];
struct jailhouse_memory mem_regions[20];
struct jailhouse_irqchip irqchips[3];
struct jailhouse_pci_device pci_devices[3];
} __attribute__((packed)) config = {
.header = {
.signature = JAILHOUSE_SYSTEM_SIGNATURE,
.revision = JAILHOUSE_CONFIG_REVISION,
.flags = JAILHOUSE_SYS_VIRTUAL_DEBUG_CONSOLE,
.hypervisor_memory = {
.phys_start = 0x83e0000000,
.size = 0x4000000,
},
.debug_console = {
.address = 0xe1010000,
.size = 0x1000,
.type = JAILHOUSE_CON_TYPE_PL011,
.flags = JAILHOUSE_CON_ACCESS_MMIO |
JAILHOUSE_CON_REGDIST_4,
},
