Before this patch: turbostat does not recognize value "3" on Ice Lake Xeon
(ICX) and Sapphire Rapids Xeon (SPR), treats it as "unknown", and does not
display any package C-states in the results table.

$(or ...) is available since GNU Make 3.81, and useful to shorten the

Covert as follows:

This patch also converts:
$(if A, A, B) --> $(or A, B)
Strictly speaking, the latter is not an equivalent conversion because
GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B)
expands to " A", while $(or A, B) expands to "A".
Anyway, preceding spaces are not significant in the code hunks I touched.

When BIOS disables turbo, the cpuinfo_max_freq will also be same as the
power up base frequency. When SST-PP causes increase in base frequency
the performance will be still limited to the old base frequency as the
cpuinfo_max_freq will not be updated.
In this case we need to update scaling_max frequency to the new
base_frequency. This will result in setting updated max performance
limit in the Pstate driver. So performance will not be limited to the
old base frequency.

There are two TCC activation temeprature.
One is the default TCC activation temperature, also known as TJ_MAX.
Another one is the effective TCC activation temperature, which is the
subtraction of default TCC activation temperature and TCC offset.
The name of variable tcc_activation_temp might be misleading here.
Thus rename tcc_activation_temp to tj_max, and use tcc_default and
tcc_offset to calculate the effective TCC activation temperature.
No functional change in this patch.

It was found that on Elkhart Lake the TSC frequency is driven by
a separate crystal-clock domain, which is different from the
BCLK domain which includes mperf. This has result in small different
speed thus inconsistence between TSC and the mperf, which caused the
Busy% to be higher than 100%. On this platform it seems that the mperf
runs faster than tsc when the CPU is 100% utilized:
delta tsc(18815473183) < delta mperf(18958403680) for 10 seconds.
To align TSC with mperf, leverage the tsc_tweak mechanism introduced for
cores newer than Skylake, so that TSC and mperf would be calculated in
the same domain.

Currently the turbostat treats ICX the same way as SKX and shares the
code among them. But one difference is that ICX does not support Package
C6 Retention, unlike SKX and CLX.
So this patch:
1. Splitting SKX and ICX in turbostat.
2. Removing Package C6 Rentention for ICX.
And after this split, it would be easier to cutomize Ice Lake Server
in turbostat in the future.

The idx_to_offset() function returns type int (32-bit signed), but
MSR_PKG_ENERGY_STAT is u32 and would be interpreted as a negative number.
The end result is that it hits the if (offset < 0) check in update_msr_sum()
which prevents the timer callback from updating the stat in the background when
long durations are used. The similar issue exists in offset_to_idx() and
update_msr_sum(). Fix this issue by converting the 'int' to 'off_t' accordingly.

This is necessary because the counter is not enabled by default,

It is possible that users manually offlined CPUs via sysfs interface
and then started this utility. In this case we will not be able to get
package and die id of the those CPUs. So add an option to force online
if required for some commands.

Some older kernels don't support reading core-power status. In that case
mailbox command fails. So, display core-power status as "unknown" instead
of supported.

The current string size to print cpulist can accommodate upto 80
logical CPUs per package. But this limit is not enough. So increase
the string size. Also prevent buffer overflow, if the string size
reaches limit.

Add a new command to get and set TRL (Turbo Ratio Limits). This will

Add a new command "turbo-mode", which allows to enable/disable
turbo mode globally. This uses base-frequency as the max frequency
when turbo-mode is disabled. This allows soft disable turbo mode
without depending on kernel or BIOS.

6d6501d912 ("tools/power/turbostat: Read energy_perf_bias from sysfs")
converted turbostat to read the energy_perf_bias value from sysfs.
However, older kernels which do not have that file yet, would fail. For
those, fall back to the MSR reading.

In some case when BIOS disabled turbo, cpufreq cpuinfo_max_freq can be
lower than base_frequency at higher config level. So, in that case set
scaling_min_freq to base_frequency.

When BIOS disables turbo, The scaling_max_freq in cpufreq sysfs will be
limited to config level 0 base frequency. But when user selects a higher
config levels, this will result in higher base frequency. But since
scaling_max_freq is still old base frequency, the performance will still
be limited. So when the turbo is disabled and cpufreq base_frequency is
higher than scaling_max_freq, update the scaling_max_freq to the
base_frequency.

Some older kernels will not have support to get CPU die_id from the
sysfs. This requires several back ports. But the tool depends on getting
die_id to match to correct CPU.
Relax this restriction and use die_id as 0 when die_id is missing. This
is not a problem as we don't have any multi-die processors with Intel SST
support.
This helps in running this tool on older kernels with just Intel SST
drivers back ported.

turbostat tends to get confused when CPUs are added and removed
while it is running.
There are races, such as checking the current cpu, and then
reading a sysfs file that depends on that cpu number.
Close the two issues that seem to come up the most.
First, there is an infinite reset loop detector --
change that to allow more resets before giving up.
Secondly, one of those file reads didn't really need
to exit the program on failure...

I've encountered an issue with x86_energy_perf_policy. If I run it on a
machine that I'm told is a qemu-kvm virtual machine running inside a
privileged container, I get the following error:
x86_energy_perf_policy: /dev/cpu/0/msr offset 0x1ad read failed: Input/output error
I get the same error in a Digital Ocean droplet, so that might be a
similar environment.
I created the following patch which is intended to give a more
user-friendly message. It's based on a patch for turbostat from Prarit
Bhargava that was posted some time ago. The patch is "[v2] turbostat:
Running on virtual machine is not supported" [1].
Given my limited knowledge of the topic, I can't say with confidence
that this is the right solution, though (that's why this is not an
official patch submission). Also, I'm not sure what the convention with
exit codes is in this tool. Also, instead of the error message, perhaps
the tool should just not print anything in this case, which is how it
behaves in a "regular" VM?

turbostat formatting is broken with ACPI CST for enumeration. The

Since the RAPL Joule Counter is 32 bit, turbostat would
only print a *star* instead of printing the actual energy
consumed to indicate the overflow due to long duration.
This does not meet the requirement from servers as the
sampling time of turbostat is usually very long on servers.
So maintain a set of MSR buffer, and update them
periodically before the 32bit MSR register is wrapped round,
so as to avoid the overflow.
The idea is similar to the implementation of ktime_get():
Periodical MSR timer:
total_rapl_sum += (current_rapl_msr - last_rapl_msr);
Using get_msr_sum() to get the accumulated RAPL:
return (current_rapl_msr - last_rapl_msr) + total_rapl_sum;
The accumulated RAPL mechanism will be turned on in next patch.
