| * tools/power/x86/intel-speed-select: Fix perf-profile command outputSrinivas Pandruvada2019-09-193-3/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit "c016ae8f9fa04d361efc8629de49ad3af12b5262 "tools/power/x86/intel-speed-select: Output success/failed for command output" introduced a regression in perf-profile outputs. With this the result field is changed to string interpreting every non zero value as errors. But these commands display on zero (>0) result. For example before this commit the display was: package-1 die-0 cpu-14 get-config-levels:4 Here the get-config-levels is interpreted as error and displayed as error with the above commit: package-1 die-0 cpu-14 get-config-levels:failed(error 4) Fix this issue by not using isst_display_result() to display such results, but define a new function which formats this data and prints.

For example: Core CPU CPU%c1 - - 100.00 0 0 100.00 0 2 100.00 1 1 100.00 1 3 100.00 But adding Busy% will fix this Core CPU Busy% CPU%c1 - - 99.77 0.23 0 0 99.77 0.23 0 2 99.77 0.23 1 1 99.77 0.23 1 3 99.77 0.23 This issue can be reproduced on most of the recent systems including Broadwell, Skylake and later. This is because if we don't select Busy% or Avg_MHz or Bzy_MHz then mperf value will not be read from MSR, so it will be 0. But this is required for C1% calculation when MSR for C1 residency is not present. Same is true for C3, C6 and C7 column selection. So add another define DO_BIC_READ(), which doesn't depend on user column selection and use for mperf, C3, C6 and C7 related counters. So when there is no platform support for C1 residency counters, we still read these counters, if the CPU has support and user selected display of CPU%c1.

The sleep time is controlled via -i option or by user sending a signal or a character to stdin. In the latter case, turbostat always adds 1 ms sleep before it reads the counters, in order to avoid larger imprecisions in the results in prints. While the 1 ms delay may be a good idea for a "dumb" user, it is a problem for an "aware" user. I do thousands and thousands of measurements over a short period of time (like 2ms), and turbostat unconditionally adds a 1ms to my interval, so I cannot get what I really need. This patch removes the unconditional 1ms sleep. This is an expert user tool, after all, and non-experts will unlikely ever use it in the non-fixed interval mode anyway, so I think it is OK to remove the 1ms delay.

Indeed, if stdin is a pipe, turbostat won't read anything from it, so it becomes impossible to get turbostat output at user-defined moments, instead of the regular intervals. There is no reason why this should works for terminals, but not for pipes. This patch improves the situation. Instead of ignoring pipes, we read data from them but gracefully handle the EOF case.

This interval is the delta between the start of one global (all counters on all CPUs) sampling and the start of another. However, this introduces a lot of jitter into the data. In order to reduce jitter, the interval calculation should be based on timestamps taken per thread and close to the start of the thread's sampling. Define a per thread time value to hold the delta between samples taken on the thread. Use the timestamp taken at the beginning of sampling to calculate the delta. Move the thread's beginning timestamp to after the CPU migration to avoid jitter due to the migration. Use the global time delta for the average time delta.
