X-Received-From: 192.55.52.120 Subject: [Qemu-devel] [PATCH v0 1/4] accel: split the tcg accelerator from accel.c file X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Yang Zhong , pbonzini@redhat.com, anthony.xu@intel.com, qemu-devel@nongnu.org Errors-To: qemu-devel-bounces+importer=patchew.org@nongnu.org Sender: "Qemu-devel" X-ZohoMail: RSF_0 Z_629925259 SPT_0 Content-Transfer-Encoding: quoted-printable MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" 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.
