But still, as you suggest, a patch like the following should be tested and
committed:
--- a/sys/dev/acpica/acpi_cpu.c
+++ b/sys/dev/acpica/acpi_cpu.c
@@ -828,7 +828,8 @@ acpi_cpu_cx_list(struct acpi_cpu_softc *sc)
sbuf_new(&sb, sc->cpu_cx_supported, sizeof(sc->cpu_cx_supported),
SBUF_FIXEDLEN);
for (i = 0; i < sc->cpu_cx_count; i++) {
- sbuf_printf(&sb, "C%d/%d ", i + 1, sc->cpu_cx_states[i].trans_lat);
+ sbuf_printf(&sb, "C%d/%d ", sc->cpu_cx_states[i].type,
+ sc->cpu_cx_states[i].trans_lat);
if (sc->cpu_cx_states[i].type < ACPI_STATE_C3)
sc->cpu_non_c3 = i;
}
P.S. I restored acpi@ cc: which I think is quite relevant, but was somehow lost.
