Hi, Testing MTTCG patch-set performance I found strange slowness with _upstream_ qemu (46bca5404b08201bb9df1ac32bc88fc7e6db1f74).
Basically booting a vexpress-a15 with "-smp 4" takes approximately forever if I use a vexpress-v2p-ca15-tc1.dtb (2x A15) dtb and 39 secs if I hack this dtb to have 4 CPUs.
This is definitely strange because if I use "-smp 2" with the same guest image it takes only 4 secs. And MTTCG patch-set seems to fix the issue as it boot in 6 secs with
"-smp 4". Is that a known issue or maybe it's my guest (linux 3.13.5)? Fred
