| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some systems /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us or /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us return a file error because of bad ACPI LPIT data from a misconfigured BIOS. turbostat interprets this failure as a fatal error and outputs turbostat: CPU LPI: No data available If the ACPI LPIT sysfs files return an error output a warning instead of a fatal error, disable the ACPI LPIT evaluation code, and continue.

| * tools/power turbostat: Also read package power on AMD F17h (Zen)Calvin Walton2019-03-201-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The package power can also be read from an MSR. It's not clear exactly what is included, and whether it's aggregated over all nodes or reported separately. It does look like this is reported separately per CCX (I get a single value on the Ryzen R7 1700), but it might be reported separately per- die (node?) on larger processors. If that's the case, it would have to be recorded per node and aggregated for the socket. Note that although Zen has these MSRs reporting power, it looks like the actual RAPL configuration (power limits, configured TDP) is done through PCI configuration space. I have not yet found any public documentation for this. Signed-off-by: Calvin Walton <calvin.walton@kepstin.ca> Signed-off-by: Len Brown <len.brown@intel.com>
| * tools/power turbostat: Add support for AMD Fam 17h (Zen) RAPLCalvin Walton2019-03-201-29/+130
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on the Open-Source Register Reference for AMD Family 17h Processors Models 00h-2Fh: https://support.amd.com/TechDocs/56255_OSRR.pdf These processors report RAPL support in bit 14 of CPUID 0x80000007 EDX, and the following MSRs are present: 0xc0010299 (RAPL_PWR_UNIT), like Intel's RAPL_POWER_UNIT 0xc001029a (CORE_ENERGY_STAT), kind of like Intel's PP0_ENERGY_STATUS 0xc001029b (PKG_ENERGY_STAT), like Intel's PKG_ENERGY_STATUS A notable difference from the Intel implementation is that AMD reports the "Cores" energy usage separately for each core, rather than a per-package total. The code has been adjusted to handle either case in a generic way. I haven't yet enabled collection of package power, due to being unable to test it on multi-node systems (TR, EPYC).

The guests have the AMD PStateDef MSR (0xC0010064 + state number) set to zero. As a result fid and did are zero and the crash occurs because of a divide by zero (cof = fid/did). This can be prevented by checking the enable bit in the PStateDef MSR before calculating cof. By doing this the value of pstate[i] remains zero and the value can be tested before displaying the active Pstates. Check the enable bit in the PstateDef register for all supported families and only print out enabled Pstates.

So it is twice as large as it should be on a typical Intel system. For example, on a 6 core Xeon system 'topo.num_cores' is 12, and on a 52 core Xeon system 'topo.num_cores' is 104. And interestingly, on a 68-core Knights Landing Intel system 'topo.num_cores' is 272, because this system has 4 logical CPUs per core. As a result, some of the turbostat calculations are incorrect. For example, on idle 52-core Xeon system when all cores are ~99% in Core C6 (CPU%c6), the summary (very first) line shows ~48% Core C6, while it should be ~99%. This patch fixes the problem by fixing 'topo.num_cores' calculation. Was: 1. Init 'thread_id' for all CPUs to -1 2. Run 'get_thread_siblings()' which sets it to 0 or 1 3. Increment 'topo.num_cores' when thread_id != -1 (bug!) Now: 1. Init 'thread_id' for all CPUs to -1 2. Run 'get_thread_siblings()' which sets it to 0 or 1 3. Increment 'topo.num_cores' when thread_id is not 0 I did not have a chance to test this on an AMD machine, and only tested on a couple of Intel Xeons (6 and 52 cores).
