qemu参数解析

启动命令：
gdb –args /usr/bin/bin/qemu-system-x86_64 linux-0.2.img -m 512 -enable-kvm -smp 1,sockets=1,cores=1,threads=1 -realtime mlock=off -device ivshmem,shm=ivshmem,size=1 -device ivshmem,shm=ivshmem1,size=2

解析后的数据结构如下：

struct QemuOptsList {
const char *name;
const char *implied_opt_name;
bool merge_lists; /* Merge multiple uses of option into a single list? */
QTAILQ_HEAD(, QemuOpts) head;
QemuOptDesc desc[];
};
struct QemuOpts {
char *id;
QemuOptsList *list;
Location loc;
QTAILQ_HEAD(, QemuOpt) head;
QTAILQ_ENTRY(QemuOpts) next;
};
struct QemuOpt {
char *name;
char *str;
const QemuOptDesc *desc;
union {
bool boolean;
uint64_t uint;
} value;
QemuOpts *opts;
QTAILQ_ENTRY(QemuOpt) next;
};


主要api都在util/qemu-option.c 文件
