![]() Slim Bootloader already calibrated TSC and provides it to U-Boot. Therefore, U-Boot does not have to re-calibrate TSC. Configuring tsc_base and clock_rate makes x86 tsc_timer driver bypass TSC calibration and use the provided TSC frequency. - Get TSC frequency from performance info hob - Set tsc_base and clock_rate for tsc_timer driver Signed-off-by: Aiden Park <aiden.park@intel.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Tested-by: Bin Meng <bmeng.cn@gmail.com> |
