Nonetheless if we try to get this information with `-cpu help`, qemu just exists with an error code and no output. Let's correct that. The code is basically a copy from target/alpha/cpu.h, but we strip the "-hexagon-cpu" suffix before printing. This is to avoid confusing situations like the following: $ qemu-hexagon -cpu help Available CPUs: v67-hexagon-cpu $ qemu-hexagon -cpu v67-hexagon-cpu ./prog qemu-hexagon: unable to find CPU model 'v67-hexagon-cpu' Signed-off-by: Matheus Tavares Bernardino Signed-off-by: Taylor Simpson Tested-by: Taylor Simpson Reviewed-by: Taylor Simpson Message-Id: --- target/hexagon/cpu.h | 3 +++ target/hexagon/cpu.c | 20 ++++++++++++++++++++ 2 files changed, 23 insertions(+) diff --git a/target/hexagon/cpu.h b/target/hexagon/cpu.h index d095dc6647..bfcb1057dd 100644 --- a/target/hexagon/cpu.h +++ b/target/hexagon/cpu.h @@ -48,6 +48,9 @@ #define TYPE_HEXAGON_CPU_V71 HEXAGON_CPU_TYPE_NAME("v71") #define TYPE_HEXAGON_CPU_V73 HEXAGON_CPU_TYPE_NAME("v73") =20 +void hexagon_cpu_list(void); +#define cpu_list hexagon_cpu_list + #define MMU_USER_IDX 0 =20 typedef struct { diff --git a/target/hexagon/cpu.c b/target/hexagon/cpu.c index d4dfc382ab..7e127059c7 100644 --- a/target/hexagon/cpu.c +++ b/target/hexagon/cpu.c @@ -31,6 +31,26 @@ static void hexagon_v69_cpu_init(Object *obj) { } static void hexagon_v71_cpu_init(Object *obj) { } static void hexagon_v73_cpu_init(Object *obj) { } =20 +static void hexagon_cpu_list_entry(gpointer data, gpointer user_data) +{ + ObjectClass *oc =3D data; + char *name =3D g_strdup(object_class_get_name(oc)); + if (g_str_has_suffix(name, HEXAGON_CPU_TYPE_SUFFIX)) { + name[strlen(name) - strlen(HEXAGON_CPU_TYPE_SUFFIX)] =3D '\0'; + } + qemu_printf(" %s\n", name); + g_free(name); +} + +void hexagon_cpu_list(void) +{ + GSList *list; + list =3D object_class_get_list_sorted(TYPE_HEXAGON_CPU, false); + qemu_printf("Available CPUs:\n"); + g_slist_foreach(list, hexagon_cpu_list_entry, NULL); + g_slist_free(list); +} + static ObjectClass *hexagon_cpu_class_by_name(const char *cpu_model) { ObjectClass *oc; --=20 2.25.1
