The turbo-freq enable with auto mode, prints result for the last possible
CPU, which is not correct when either CPU is not present or user wants
command to be limited to a single die/package. For example, in the
below command user wants to limit to die/package 0, but the
"turbo-freq --auto" result is displayed using the other package.
$ sudo intel-speed-select -c 0 turbo-freq enable -a
Intel(R) Speed Select Technology
package-0
die-0
cpu-0
turbo-freq
enable:success
package--1
die-0
cpu-31
turbo-freq --auto
enable:success
Since we do have to traverse all CPUs, don't display CPU info for
"turbo-freq --auto", as we already displayed the result for
turbo-freq enable with the CPU information.
With the fix, the same command results in:
$ sudo intel-speed-select -c 0 turbo-freq enable -a
Intel(R) Speed Select Technology
package-0
die-0
cpu-0
turbo-freq
enable:success
turbo-freq --auto

There are some platforms, where there limited support of Intel(R) SST
features. Here perf-profile has only one base configuration and limited
support of commands. But still has support for discovery of base-freq and
turbo-freq features. So it is important to show minimum features to use
base-freq and turbo-freq features.
Here the change are:
- When there is no support of CONFIG_TDP_GET_LEVELS_INFO, then instead
of treating this as fatal error, treat this with number of config levels
= 0, that means only base level 0 is present.
- There is no support of mail box commands to get base frequencies or
turbo frequencies. Here present base frequency by reading cpufreq
base freq and turbo frequency by reading MSR 0x1AD.

Enable command also have support for --auto|-a option, which sets cpufreq

The turbo-freq feature is dependent on the core-power feature. If the
core-power feature is disabled while the turbo-freq feature is enabled,
this will break the turbo-freq feature. This is a firmware limitation,
where they can't return error under this scenario.
So when trying to disable core-power, make sure that the turbo-freq
feature is not enabled. If it enabled, return error if user is trying to

users don't have to take multiple steps to enable turbo-freq feature. For

While here also print the error to output when clos configuration fails.

commit "c016ae8f9fa04d361efc8629de49ad3af12b5262
"tools/power/x86/intel-speed-select: Output success/failed for command

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

get-config-levels:failed(error 4)

cpumasks are allocated by calling the alloc_cpu_mask() function and are
never free'd. They should be free'd after the commands have run.
Fix the memory leaks by calling free_cpu_set().

The intel-speed-select tool currently only outputs a hexidecimal CPU mask,
which requires translation for use with kernel parameters such as
isolcpus.
Along with the CPU mask, output a human readable CPU list.

The isst_send_msr_command() function will read 8 bytes but we are
passing an address to an int (4 bytes) so it results in a read overflow.

turbostat: Also read package power on AMD F17h (Zen)") add AMD Fam 17h
RAPL support.
Hygon Family 18h(Dhyana) support RAPL in bit 14 of CPUID 0x80000007 EDX,
and has MSRs RAPL_PWR_UNIT/CORE_ENERGY_STAT/PKG_ENERGY_STAT. So add Hygon
Dhyana Family 18h support for RAPL.
Already tested on Hygon multi-node systems and it shows correct per-core
energy usage and the total package power.

In some case C1% will be wrong value, when platform doesn't have MSR for
C1 residency.
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.

Turbostat works by taking a snapshot of counters, sleeping, taking another
snapshot, calculating deltas, and printing out the table.
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.
