[Qemu-devel] [PATCH v0 1/4] accel: split the tcg accelerator from accel.c file

[Yang Zhong <yang.zhong@intel.com>]

there are two accelerators in qemu, kvm and tcg.  kvm
accelerator is defined in kvm-all.c, but tcg accelerator
is defined in accel.c file. we split tcg accelerator from
accel.c file and create one new accel directory, which
will include kvm and tcg accel files.
