From: Len Brown <len.brown@intel.com> Add a digit of precision to the --debug output for frequency range. This is useful when BCLK is not an integer. old: 6 * 83 = 500 MHz max efficiency frequency 26 * 83 = 2166 MHz base frequency new: 6 * 83.3 = 499.8 MHz max efficiency frequency 26 * 83.3 = 2165.8 MHz base frequency Signed-off-by: Len Brown <len.brown@intel.com> --- tools/power/x86/turbostat/turbostat.c | 42 +++++++++++++++++------------------ 1 file changed, 21 insertions(+), 21 deletions(-) diff --git a/tools/power/x86/turbostat/turbostat.c b/tools/power/x86/turbostat/turbostat.c index 19802be6dc02..762b81497c3b 100644 --- a/tools/power/x86/turbostat/turbostat.c +++ b/tools/power/x86/turbostat/turbostat.c @@ -1581,11 +1581,11 @@ dump_nhm_platform_info(void) fprintf(outf, "cpu%d: MSR_PLATFORM_INFO: 0x%08llx\n", base_cpu, msr);
