Hi,
Looks like for this SoC turbo state is not available, so try the following (enable speedstep regardless if turbo state is available or not, as you need speedstep!) :
--- a/src/soc/intel/denverton_ns/cpu.c
+++ b/src/soc/intel/denverton_ns/cpu.c
@@ -71,11 +71,11 @@ static void denverton_core_init(struct device *cpu)
enable_turbo();
/* Enable speed step. */
- if (get_turbo_state() == TURBO_ENABLED) {
+// if (get_turbo_state() == TURBO_ENABLED) {
msr = rdmsr(IA32_MISC_ENABLE);
msr.lo |= SPEED_STEP_ENABLE_BIT;
wrmsr(IA32_MISC_ENABLE, msr);
- }
+// }
}
King regards,
