[Qemu-devel] [PATCH 6/8] tcg/tci: disable MTTCG if TCI is enabled

[Philippe Mathieu-Daudé]

TCI + MTTCG cause strange errors...

  $ arm-softmmu/qemu-system-arm -machine raspi2 -cpu cortex-a7 -smp 4 -accel 
tcg,thread=multi -kernel kernel7.img
  qemu-system-arm: Guest expects a stronger memory ordering than the host 
provides
  This may cause strange/hard to debug errors
  Segmentation fault (core dumped)
