Exactly 2G.
qemu-system-ppc64 -M pseries -m 2G ....
The boot normally continue like this:
rfi-flush: fallback displacement flush available
count-cache-flush: software flush disabled.
stf-barrier: hwsync barrier available
PCI host bridge /pci@800000020000000 ranges:
IO 0x0000200000000000..0x000020000000ffff -> 0x0000000000000000
MEM 0x0000200080000000..0x00002000ffffffff -> 0x0000000080000000
MEM 0x0000210000000000..0x000021ffffffffff -> 0x0000210000000000
PPC64 nvram contains 65536 bytes
barrier-nospec: using ORI speculation barrier
Zone ranges:
Normal [mem 0x0000000000000000-0x000000007fffffff]
Movable zone start for each node
Early memory node ranges
node 0: [mem 0x0000000000000000-0x000000007fffffff]
Initmem setup node 0 [mem 0x0000000000000000-0x000000007fffffff]
