6d306d6ec7 tools/power/turbostat: Replace raw value cpu model with Macro 
Kernel already has
 #define INTEL_FAM6_NEHALEM_G	0x1F /* Auburndale / Havendale */

Use standard Macro for CPU Model instead of raw value.

2c019d6579 tools/power/turbostat: Support alternative graphics sysfs knobs 
/sys/class/graphics/fb0/device/drm/card0/ and /sys/class/drm/card0/
point to the same device node.
But in some cases, one exists and the other one does not.

Prefer to use /sys/class/drm/card0/, and fall back to
/sys/class/graphics/fb0/device/drm/card0/.

This recovers the "GFXMHz" and "GFXAMHz" columns on some platforms like
a SPR server.

4d1827485a tools/power/turbostat: Fix failure with new uncore sysfs 
On some platforms, turbostat fails during launch time like below,

turbostat version 2023.03.17 - Len Brown <lenb@kernel.org>
...
cpu40: MSR_IA32_PACKAGE_THERM_STATUS: 0x884c0000 (24 C)
cpu40: MSR_IA32_PACKAGE_THERM_INTERRUPT: 0x00000003 (100 C, 100 C)
turbostat: snapshot_sysfs_counter(/sys/devices/system/cpu/intel_uncore_frequency/package_00_die_00/current_freq_khz): No data available

This is because new uncore sysfs is used on these platforms as
introduced by commit 9b8dea80e3 ("platform/x86/intel-uncore-freq:
Support for cluster level controls").

With the new uncore sysfs interface,
/sys/devices/system/cpu/intel_uncore_frequency/package_00_die_00/current_freq_khz
is still available, but reading it fails.

How to support the fabric cluster level uncore sysfs is not settled yet,
as a short term fix, clear the BIC_UNCORE_MHZ bit when new sysfs I/F is
detected.

99481d2195 cpupower: Fix cpuidle_set to accept only numeric values for idle-set operation. 
For both the d and e options in 'cpupower idle_set' command, an
atoi() conversion is done without checking if the input argument
is all numeric. So, an atoi conversion is done on any character
provided as input and the CPU idle_set operation continues with
that integer value, which may not be what is intended or entirely
correct.

The output of cpuidle-set before patch is as follows:

[root@xxx cpupower]# cpupower idle-set -e 1$
Idlestate 1 enabled on CPU 0
[snip]
Idlestate 1 enabled on CPU 47

[root@xxx cpupower]# cpupower idle-set -e 11
Idlestate 11 not available on CPU 0
[snip]
Idlestate 11 not available on CPU 47

[root@xxx cpupower]# cpupower idle-set -d 12
Idlestate 12 not available on CPU 0
[snip]
Idlestate 12 not available on CPU 47

[root@xxx cpupower]# cpupower idle-set -d qw
Idlestate 0 disabled on CPU 0
[snip]
Idlestate 0 disabled on CPU 47

This patch adds a check for both d and e options in cpuidle-set.c
to see that the idle_set value is all numeric before doing a
string-to-int conversion using strtol().

The output of cpuidle-set after the patch is as below:

[root@xxx cpupower]# ./cpupower idle-set -e 1$
Bad idle_set value: 1$. Integer expected

[root@xxx cpupower]# ./cpupower idle-set -e 11
Idlestate 11 not available on CPU 0
[snip]
Idlestate 11 not available on CPU 47

[root@xxx cpupower]# ./cpupower idle-set -d 12
Idlestate 12 not available on CPU 0
[snip]
Idlestate 12 not available on CPU 47

[root@xxx cpupower]# ./cpupower idle-set -d qw
Bad idle_set value: qw. Integer expected

4ebde55b7d tools/power/x86/intel-speed-select: Adjust scope of core-power config 
When core-power configuration or enabled is modified, this is only done
for compute dies. But the config must also be set to cores with no CPUs.
Without this the configuration is not affective.

On displaying config information, allow display for non compute dies
also.

c2adb1877b cpupower: Make TSC read per CPU for Mperf monitor 
System-wide TSC read could cause a drift in C0 percentage calculation.
Because if first TSC is read and then one by one mperf is read for all
cpus, this introduces drift between mperf reading of later CPUs and TSC
reading.  To lower this drift read TSC per CPU and also just after mperf
read.  This technique improves C0 percentage calculation in Mperf monitor.

Before fix: (System 100% busy)

e652be0f59 cpupower:Fix resource leaks in sysfs_get_enabled() 
The sysfs_get_enabled() opened file processor not closed,
may cause a file handle leak.
Putting error handling and resource cleanup code together
makes the code easy to maintain and read.
Removed the unnecessary else if branch from the original
function, as it should return an error in cases other than '0'.

34ea427e01 PM: tools: sleepgraph: Recognize "CPU killed" messages 
On the arm64 platform with PSCI, the core log of CPU offline is as
follows:

[  100.431501] CPU1: shutdown
[  100.454820] psci: CPU1 killed (polled 20 ms)
[  100.459266] CPU2: shutdown
[  100.482575] psci: CPU2 killed (polled 20 ms)
[  100.486057] CPU3: shutdown
[  100.513974] psci: CPU3 killed (polled 28 ms)
[  100.518068] CPU4: shutdown
[  100.541481] psci: CPU4 killed (polled 24 ms)

Prevent sleepgraph from mistakenly treating the "CPU up" message as part
of the suspend flow (because it should be regarded as part of the resume
flow) by making it recognize the "CPU* killed" messages above.

0417552730 pm-graph: Update to v5.11 
install_latest_from_github.sh:
 - Added a new script which allows users to install the latest pm-graph
   from the upstream github repo. This is useful if the kernel source
   version has issues that have already been fixed in github.

sleepgraph.py:
 - Updated all the dmesg suspend/resume PM print formats to be able to
   process recent timelines using dmesg only.

 - Added ethtool output to the log for the system's ethernet device id the
   ethtool exists. This helps in debugging network issues.

 - Made the tool more robustly handle events where mangled dmesg or ftrace
   outputs do not include all the requisite data. The tool fails gracefully
   instead of creating a garbled timeline.

Emerald Rapids doesn't specify TRL (Turbo Ratio Limits) based instruction

Increase TRL levels to 5 for Emerald Rapids. Also change display to show
by level number. Show only non zero level values.

997074df65 tools/power/x86/intel-speed-select: Use cgroup v2 isolation 
On supported systems, it is possiible to isolate CPUs instead of
CPU online/offline. This is optional and can be specified using
-g option when running as daemon or in combination with -o option
for SST-PP level change.

CPU isolation doesn't isolate IRQs. So IRQs needs to be moved away
from isoolated CPUs. This can be done via IRQ sysfs or irqbalance daemon.

The IRQ balance daemon is also capable to parse thermal HFI messages to
move IRQs away from CPUS, which are supposed be isolated. But this
requires version released after July 2022.

instead.
