Kernel developers often need to diagnose remote customer systems
with the latest turbostat, yet customers are running binary distros
with out-dated turbostat and the customer has no experience
cloning linux kernel trees.
Add a turbostat "snapshot" makefile target to create a standalone
source snapshot from the developer's git tree, appropriately hacked
so that the customer can build turbostat without a kernel tree.
Include the turbostat binary in the snapshot, for convenience in
those situations where the source and destination are trusted,
(and have new enough glibc to execute).
The snapshot is named with the date it was taken rather than
the turbostat VERSION, as it could occur between VERSIONS...

Use of the CPU MSR driver is now optional.
Perf is now preferred for many counters.
Non-root users can now execute turbostat, though with limited function.
Add counters for some new GFX hardware.
Minor fixes.

Running turbostat on a 16 socket HPE Scale-up Compute 3200 (SapphireRapids) fails with:
turbostat: /sys/devices/system/cpu/intel_uncore_frequency/package_010_die_00/current_freq_khz: open failed: No such file or directory
We observe the sysfs uncore frequency directories named:
...
package_09_die_00/
package_10_die_00/
package_11_die_00/
...
package_15_die_00/
The culprit is an incorrect sprintf format string "package_0%d_die_0%d" used
with each instance of reading uncore frequency files. uncore-frequency-common.c
creates the sysfs directory with the format "package_%02d_die_%02d". Once the
package value reaches double digits, the formats diverge.
Change each instance of "package_0%d_die_0%d" to "package_%02d_die_%02d".

If user request --no-msr or is not able to access the MSRs,

Because MSR access permission checks are done after the cmdline is

By using the perf API we spend less time in between the reads of the
counters, resulting in more accurate calculations of the dependent
metrics.
Using perf API is also usually faster overall, although cache miss, if
we get one, is more costly when using perf vs MSR driver.
We would fallback to the msr reads if the sysfs isn't there or when in

turbostat prints the abnormal SYS%LPI across suspend-to-idle:
SYS%LPI = 114479815993277.50
This is reproduced by:
Run a freeze cycle, e.g. "sleepgraph -m freeze -rtcwake 15".
Then do a reboot. After boot up, launch the suspend-idle-idle
and check the SYS%LPI field.
The slp_so residence counter is in LPIT table, and BIOS does not
clears this register across reset. The PMC expects the OS to calculate
the LPI residency based on the delta. However, there is an firmware
issue that the LPIT gets cleared to 0 during the second suspend
to idle after the reboot, which brings negative delta value.

When running turbostat, a system with 512 cpus reaches the limit for
maximum number of file descriptors that can be opened. To solve this
problem, the limit is raised to 2^15, which is a large enough number.
Below data is collected from AMD server systems while running turbostat:
|-----------+-------------------------------|
| # of cpus | # of opened fds for turbostat |
|-----------+-------------------------------|
| 128 | 260 |
|-----------+-------------------------------|
| 192 | 388 |
|-----------+-------------------------------|
| 512 | 1028 |
|-----------+-------------------------------|
So, the new max limit would be sufficient up to 2^14 cpus (but this
also depends on how many counters are enabled).

This version addresses issues with:
- When CPU 0 hotplug is not possible, try cgroup v2 isolation
without any user input
- Fix turbo mode enable/disable swapped
- Sanitize command line integer and hex arguments
- Add more error messages
- Increase CPU count in one request
Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>
From kernel version 6.5, CPU 0 hotplug capability is deprecated.
If some SST profile doesn't have CPU 0, then it is no longer possible to
offline CPU 0. This means that user space threads will still run on
CPU 0.
To workaround this issue, use cgroup v2 isolation feature. Whenever there
/sys/devices/system/cpu/cpu0/online file is absent or open fails, isolate
CPU 0 via CPU cgroup v2 isolation. Also add a command line option to
force even if the /sys/devices/system/cpu/cpu0/online is present.
The previous commit "01bcb56f059e ("tools/power/x86/intel-speed-select:
Prevent CPU 0 offline") was just warning about this issue based on the
kernel version 6.5 and above. With this new approach, instead of warning

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.

MAX_PACKAGE_COUNT limits the intel-speed-select to systems with 8 sockets or fewer.
On a system with more than 8 sockets intel-speed-select silently ignores everything
beyond the 8th socket, rendering the tool useless for those systems.
Increase MAX_PACKAGE_COUNT to support systems with up to 32 sockets.

Fix CPU count display for power domain != 0. In the function
punit_id is always 0, so it never incremented cpu count for power
domain id != 0.

actually received from the kernel.

This version addresses issues with core power configuration for

Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>
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.

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.
