Zhang Rui e9f79348ae tools/power/x86/intel-speed-select: Always invoke isst_fill_platform_info
isst_fill_platform_info fills platform specific information.
And it is the proper place to set platform specific callbacks, as done in
next patch.

As the platform specific callbacks are needed in all cases, including
isst_print_platform_information.

Todd Brandt 6fa7f53735 pm-graph: sleepgraph: Avoid crashing on binary data in device names
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.

Uncore P1 is not uncore minmum frequency. This is uncore base frequency.
Correct display from uncore-frequency-min(MHz)
to uncore-frequency-base(Mhz).

To get uncore min frequency use mailbox command
CONFIG_TDP_GET_RATIO_INFO. Use this mailbox to get uncore frequency
limits when present.

Srinivas Pandruvada 6ed9e36315 tools/power/x86/intel-speed-select: turbo-freq auto mode with SMT off
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.

Ross Zwisler cf3e025186 PM: tools: use canonical ftrace path
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.

Thomas Renninger 8c37df3d63 cpupower: rapl monitor - shows the used power consumption in uj for each rapl domain
This CPU power monitor shows the power consumption
as exposed by the powercap subsystem, cmp with:
Documentation/power/powercap/powercap.rst

cpupower monitor -m RAPL
    | RAPL
 CPU| pack | core | unco
   0|6853926|967832|442381
   8|6853926|967832|442381
   1|6853926|967832|442381
   9|6853926|967832|442381

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.

Thomas Renninger c2294c1496 cpupower: Introduce powercap intel-rapl library and powercap-info command
Read out powercap zone information via:
cpupower powercap-info
and show the zone hierarchy to the user:

./cpupower powercap-info
Driver: intel-rapl
Powercap domain hierarchy:

Zone: package-0 (enabled)
Power consumption can be monitored in micro Watts

        Zone: core (disabled)
        Power consumption can be monitored in micro Watts

        Zone: uncore (disabled)
        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
-> uncore

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

intel-rapl/intel-rapl:1
-> psys

This could get enhanced in:
struct powercap_zone *powercap_init_zones()
and adopted to walk through all intel-rapl zones, but
also to other powercap drivers like dtpm
(Dynamic Thermal Power Management framework),
cmp with: drivers/powercap/dtpm_*

Saket Kumar Bhaskar 5975e2558e tools/cpupower: Choose base_cpu to display default cpupower details
The default output of cpupower info utils shows unexpected output
when CPU 0 is disabled.

Considering a case where CPU 0 is disabled, output of cpupower idle-info:

Before change:
cpupower idle-info
CPUidle driver: pseries_idle
CPUidle governor: menu
analyzing CPU 0:
 *is offline

After change:
./cpupower idle-info
CPUidle driver: pseries_idle
CPUidle governor: menu
analyzing CPU 50:

Number of idle states: 2
Available idle states: snooze CEDE
snooze:
Flags/Description: snooze
Latency: 0
Usage: 101748
Duration: 2724058
CEDE:
Flags/Description: CEDE
Latency: 12
Usage: 270004
Duration: 283019526849

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
currently executing.

Zhang Rui 850337ec7b tools/power/x86/intel-speed-select: Introduce struct isst_id
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.

Introduce struct isst_id to represent a SST Power Domain.

All core APIs are converted to use struct isst_id as parameter instead of
using cpu id.

The ACC (automatic C-state conversion) feature was available on Sky Lake and

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

Artem Bityutskiy 0e4d42af81 tools/power turbostat: fix SPR PC6 limits
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.

Len Brown a5c6d65d06 tools/power turbostat: Show uncore frequency
When CONFIG_INTEL_UNCORE_FREQ_CONTROL is effective,
(Linux 5.9 and later), print the current (and default)
min and max uncore frequency limits.

When that driver provides the current uncore frequency
(Linux 5.18 and later), print a UncMHz column
reflecting the current uncore frequency.

Note that UncMHz is an instantaneous sample, not an average.

eg.

$ sudo ./turbostat -S --show frequency
