I take it the kernel is loaded at 0xffbe00 which is right at the edge of
the low ram region. In fact after issuing the cell load command and
adjusting the path for the loader I get JAILHOUSE_CELL_LOAD: Invalid
argument.
Just tested cell-linux in a qemu machine, there it works, with pretty
similar addresses, which got me confused.
After double-checking it: 0xffb.e00 is *not* at the edge of low mem:
Low mem is 0x000.000 -- 0x0ff.fff
Comm region is 0x100.000 -- 0x100.fff
0xffb.e00 is (obviously) way above.
Please try to set your high mem's .virt_start to 0x200000. Then,
0xffbe00 is offsetted ~16MB inside your highmem, and it should work!
IOW:
/* high RAM */
{
.phys_start = 0x42300000,
.virt_start = 0x200000,
.size = 0x11000000,
.flags = JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE |
JAILHOUSE_MEM_EXECUTE |
JAILHOUSE_MEM_LOADABLE,
},
Thanks
