A previous change amended try_to_freeze_tasks() with the "what"
variable pointing to a string describing the group of tasks subject to
the freezing which may be used in the error message in there too, so
make that happen.
Accordingly, update sleepgraph.py to catch the modified error message
as appropriate.

Pull cpupower utility updates for 6.2-rc1 from Shuah Khan:
"This cpupower update for Linux 6.2-rc1 consists of:
- enhancement to choose base_cpu to display default cpupower details
instead of picking cpu 0 and failing show information when it is
offline. This change ensure user will see power information on
the cpu the tool runs on.
- adds Georgian translation to cpupower documentation.

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

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.

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),

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.

SST control is power-domain based rather than cpu based, on all the

SST core APIs uses cpu id as parameter, and use the underlying pkg_id and

and introduces obscure logics in the code.

The ACC (automatic C-state conversion) feature was available on Sky Lake and
Cascade Lake Xeons (SKX and CLX), but it is not available on Ice Lake and
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.

The 'automatic_cstate_conversion_probe()' function has a too long 'if'
statement, convert it to a 'switch' statement in order to improve code
readability a bit.

Before this patch, SPR platform was considered identical to ICX platform. This
patch separates SPR support from ICX.
This patch is a preparation for adding SPR-specific package C-state limits
support.
