From: KONRAD Frederic <fred.kon...@greensocs.com> Those are some icount patches required for reverse execution.
It introduces an icount clock which is only growing with icount. It allows QEMU to migrate icount so virtual clock is kept if the VM is migrated in icount mode (which is mandatory for migration based snapshot). They are rebased on uq/master of git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git And can be cloned here: git://git.greensocs.com/qemu_cexe.git:cexe_1_3_v6_rebased Thanks, Fred KONRAD Frederic (7): icount: put icount variables into TimerState. migration: migrate icount fields. migration: make qemu_savevm_state public. icount: introduce icount timer. icount: check for icount clock deadline when cpu loop exits. icount: make icount extra computed on icount clock as well. timer: add cpu_icount_to_ns function. cpus.c | 95 ++++++++++++++++++++++++++++++++++++++----------- include/qemu/timer.h | 10 +++++- include/sysemu/sysemu.h | 1 + qemu-timer.c | 8 ++++- savevm.c | 2 +- stubs/cpu-get-icount.c | 2 +- 6 files changed, 94 insertions(+), 24 deletions(-) -- 1.9.0
