Almost everything went well, but when I started the fourth cell
(bare-metal), I got this error, and jailhouse hangs, so I am able to
1- create two linux non-root cells and inter-cell communication works fine,
and(including ethernet)
2- one bare-metal and linux non-root cell.(inter-cell communication works
fine (also ethernet)
I added one region for the newly created cell in all files with taking care
of correct flags, enlarged the state memory region and the all-cells R/W
memory region, and here is what I edited in the root cell:
Adding virtual PCI device 00:00.0 to cell "rpi4-linux-demo-2"
Shared memory connection established, peer cells:
/* IVSHMEM 0001:00:00.0 (demo) */
.type = JAILHOUSE_PCI_TYPE_IVSHMEM,
.domain = 1,
.bdf = 0 << 3,
.bar_mask = JAILHOUSE_IVSHMEM_BAR_MASK_INTX,
.shmem_regions_start = 0,
.shmem_dev_id = 0,
.shmem_peers = 4,
.shmem_protocol = JAILHOUSE_SHMEM_PROTO_UNDEFINED,
},
And in any other cell i change only the dev_id, so I have 0,1,2,3, the
second PCI is an VETH and is working fine for both linux cells together,
the problem only comes if I created the baremetal cell.
