New platforms may have more than 1 punit in a Package/Die, thus it can
have multiple power domains in a Package/Die. Package id and die id is not
sufficient to refer to a specific Power domain.

Punit id can also be retrieved from ISST_IF_GET_PHY_ID.
punit id is unique within a Package/Die, and together with Package id and
Die id, they can be used to refer to a specific SST power domain.
For current platforms, Punit id is always Zero. So no functional changes
are expected for the current platforms.

A regression has occurred in the hid-sensor code where a device
name string has not been initialized to 0, and ends up without
a NULL char and is printed with %s. This includes random binary
data in the device name, which makes its way into the ftrace output
and ends up crashing sleepgraph because it expects the ftrace output
to be ASCII only.
For example: "HID-SENSOR-INT-020b?.39.auto" ends up in ftrace instead
of "HID-SENSOR-INT-020b.39.auto". It causes this crash in sleepgraph:
File "/usr/bin/sleepgraph", line 5579, in executeSuspend
for line in fp:
File "/usr/lib/python3.10/codecs.py", line 322, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position
1568: invalid start byte
The issue is present in 6.3-rc1 and is described in full here:
https://bugzilla.kernel.org/show_bug.cgi?id=217169
A separate fix has been submitted to have this issue repaired, but
it has also exposed a larger bug in sleepgraph, since nothing should
make sleepgraph crash. Sleepgraph needs to be able to handle binary
data showing up in ftrace gracefully.
Modify the ftrace processing code to treat it as potentially binary
and to filter out binary data and leave just the ASCII.

When SMT is disabled from kernel command line, sibling CPUs still
appears in the sysfs as offline CPUs. This is a problem when turbo-freq
is enabled in auto mode. They are still assigned to CLOS value
of 3 as they are still in the present CPU list. But they are not in the
sibling list of a CPU. When the CPU is a high priority CPU, because of
sibling it will be still set to CLOS to 3 as CLOS is assigned at core
level not at CPU level.
So, avoid setting CLOS 3 to offline CPU.

The canonical location for the tracefs filesystem is at /sys/kernel/tracing.
But, from Documentation/trace/ftrace.rst:
Before 4.1, all ftrace tracing control files were within the debugfs
file system, which is typically located at /sys/kernel/debug/tracing.
For backward compatibility, when mounting the debugfs file system,
the tracefs file system will be automatically mounted at:
/sys/kernel/debug/tracing
A few scripts in tools/power still refer to this older debugfs path, so
let's update them to avoid confusion.

Unfortunately RAPL domains cannot be directly mapped to the corresponding
CPU socket/package, core it belongs to.
Not sure this is possible at all with the current data exposed from the
kernel.
Still it can be worthful information for developers trying to optimize
power consumption of workloads or their system in general.

Read out powercap zone information via:

Power consumption can be monitored in micro Watts

Power consumption can be monitored in micro Watts
Zone: dram (disabled)
Power consumption can be monitored in micro Watts
There is a dummy -a option for powercap-info which can/should be used to
show more detailed info later. Like that other args can be added easily
later as well.
A enable/disable option via powercap-set subcommand is also an enhancement
for later.
Also not all RAPL domains are shown. The func walking through RAPL
subdomains is restricted and hardcoded to: "intel-rapl/intel-rapl:0"
On my system above powercap domains map to:
intel-rapl/intel-rapl:0
-> pack (age-0)
intel-rapl/intel-rapl:0/intel-rapl:0:0
-> core
intel-rapl/intel-rapl:0/intel-rapl:0:1

Missing ones on my system are:
intel-rapl-mmio/intel-rapl-mmio:0
-> pack (age-0)
intel-rapl/intel-rapl:1

This could get enhanced in:
struct powercap_zone *powercap_init_zones()

If -c option is not passed, CPU 0 was chosen as the default chosen CPU to
display details. However when CPU 0 is offline, it results in showing
unexpected output. This commit chooses the base_cpu
instead of CPU 0, hence keeping the output more relevant in all cases.
The base_cpu is the number of CPU on which the calling thread is

tools/power turbostat: version 2022.10.04
tools/power turbostat: Use standard Energy Unit for SPR Dram RAPL domain
tools/power turbostat: Do not dump TRL if turbo is not supported
tools/power turbostat: Add support for MeteorLake platforms
tools/power turbostat: Add support for RPL-S
Intel Xeon servers used to use a fixed energy resolution (15.3uj) for

cpu_map already has the cpu package id, die id information.

SST control is power-domain based rather than cpu based, on all the
systems including Sapphire Rapids and ealier.
SST core APIs uses cpu id as parameter, and use the underlying pkg_id and
die_id information to find a power domain, this is not straight forward
and introduces obscure logics in the code.

Sapphire Rapids Xeons (ICX and SPR). Therefore, stop decoding it for ICX and
SPR.

Sapphire Rapids Xeon (SPR) supports 2 flavors of PC6 - PC6N (non-retention) and
PC6R (retention). Before this patch we used ICX package C-state limits, which
was wrong, because ICX has only one PC6 flavor. With this patch, we use SKX PC6
limits for SPR, because they are the same.

It would be handy to have cmdline in turbostat output. For example,
according to the turbostat output, there are no C-states requested.
In this case the user is very curious if something like
intel_idle.max_cstate=0 was used, or may be idle=none too. It is
also curious whether things like intel_pstate=nohwp were used.

Currently, there are a number of variables which are displayed by
default, enabled with -e all, and listed by --list, but which you can
not give to --enable/-e.
So you can enable CPU0c1 (in the bic array), but you can't enable C1 or
C1% (not in the bic array, but exists in sysfs).
This runs counter to both the documentation and user expectations, and
it's just not very user friendly.
As such, the mechanism used by --hide has been duplicated, and is now
also used by --enable, so we can handle unknown names gracefully.
Note: One impact of this is that truly unknown fields given to --enable
will no longer generate errors, they will be silently ignored, as --hide
does.

Build of intel-speed-select will fail if you run:

gcc -O2 -Wall -g -D_GNU_SOURCE -Iinclude -I/usr/include/libnl3 -Wl,--as-needed -lnl-genl-3 -lnl-3 intel-speed-select-in.o -o intel-speed-select

...
In this case the problem is that order when linking matters when using
the flag -Wl,--as-needed, symbols not used at that point are discarded.
So since intel-speed-select-in.o comes after, at that point the
libraries/symbols are already discarded and then missing/undefined
references are reported.
To fix this, make sure we specify LDFLAGS after the object file.

The legacy ACPI hardware P-States function has 3 P-States on ACPI table,
the CPU frequency only can be switched between the 3 P-States. While the
processor supports the boost state, it will have another boost state
that the frequency can be higher than P0 state, and the state can be
decoded by the function of decode_pstates() and read by
amd_pci_get_num_boost_states().
However, the new AMD P-State function is different than legacy ACPI
hardware P-State on AMD processors. That has a finer grain frequency
range between the highest and lowest frequency. And boost frequency is
actually the frequency which is mapped on highest performance ratio. The
similar previous P0 frequency is mapped on nominal performance ratio.
If the highest performance on the processor is higher than nominal
performance, then we think the current processor supports the boost
state. And it uses amd_pstate_boost_init() to initialize boost for AMD
P-State function.

The processor with AMD P-State function also supports legacy ACPI
hardware P-States feature as well. Once driver sets AMD P-State eanbled,
the processor will respond the finer grain AMD P-State feature instead of

This patch also converts:

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)

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.

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.
