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.
No functional change in this patch.

For Atom CPUs that have core cstate deeper than C6,
MSR_CORE_C6_RESIDENCY actually returns the residency for both CC6 and
deeper Core cstates.
Thus, the real Core C6 residency should be the subtraction of

C-state pre-wake setting[1] is an optimization for some Intel CPUs to
be woken up from deep C-states in order to reduce latency. According to
the spec, the BIT30 is the C-state Pre-wake Disable. Expose this setting
accordingly.
Sample output from turbostat:

It was found that on Elkhart Lake the TSC frequency is driven by
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.

The idx_to_offset() function returns type int (32-bit signed), but
MSR_PKG_ENERGY_STAT is u32 and would be interpreted as a negative number.
The end result is that it hits the if (offset < 0) check in update_msr_sum()
which prevents the timer callback from updating the stat in the background when
long durations are used. The similar issue exists in offset_to_idx() and
update_msr_sum(). Fix this issue by converting the 'int' to 'off_t' accordingly.

It was reported that on Zen+ system turbostat started exiting,
which was tracked down to the MSR_PKG_ENERGY_STAT read failing because
offset_to_idx wasn't returning a non-negative index.
This patch combined the modification from Bingsong Si and

MSR_PKG_ENERGY_STATUS.

Use linux-perf to access the hardware instructions-retired counter.
This is necessary because the counter is not enabled by default,
and also the counter is prone to roll-over -- both of which
perf manages.
It is not necessary to use perf for the cycle counter,
because turbostat already needs to collect delta-aperf
to calcuate frequency.

ACPICA's internal message printing macros outside ACPICA and do
some related code cleanups (Rafael Wysocki).
- Modify the device enumeration code to turn off all of the unused
ACPI power resources at the end (Rafael Wysocki).
- Change the ACPI power resources handling code to turn off unused
ACPI power resources without checking their status which should not
be necessary by the spec (Rafael Wysocki).
- Add empty stubs for CPPC-related functions to be used when
CONFIG_ACPI_CPPC_LIB is not set (Rafael Wysocki).
- Simplify device enumeration code (Rafael Wysocki).

handling take over on hardware-reduced systems (Hans de Goede).
- Introduce acpi_dev_get() and switch over the ACPI core code to
using it (Andy Shevchenko).
- Use kobj_attribute as callback argument instead of a local struct
type in the CPPC linrary code (Nathan Chancellor).
- Drop unneeded initializatio of a static variable from the ACPI
processor driver (Tian Tao).
- Drop unnecessary local variable assignment from the ACPI APEI code
(Colin Ian King).

It is possible that users manually offlined CPUs via sysfs interface
and then started this utility. In this case we will not be able to get
package and die id of the those CPUs. So add an option to force online

The current string size to print cpulist can accommodate upto 80

- Updates to the cpupower command to add support for AMD family 0x19
and cleanup the code to remove many of the family checks to make
future family updates easier.
- Adding Makefile dependencies for install targets to allow building
cpupower in parallel rather than serially.

6d6501d912 ("tools/power/turbostat: Read energy_perf_bias from sysfs")
converted turbostat to read the energy_perf_bias value from sysfs.
However, older kernels which do not have that file yet, would fail. For
those, fall back to the MSR reading.

This may have previsously been set to validate the MSR_AMD_PSTATE_STATUS

Add a check in get_cpu_info() for the ability to read frequencies

The cpuid flag is set when CPUID_80000007_EDX[7] is set,
which is all families >= 10h. The check excludes family 14h
because HW pstate reporting was not implemented on family 14h.

The msr_pstate union struct named fam17h_bits is misleading since
this is the struct to use for all families >= 0x17, not just
for family 0x17. Rename the bits structs to be 'pstate' (for pre
family 17h CPUs) and 'pstatedef' (for CPUs since fam 17h) to align
closer with PPR/BDKG (1) naming.
There are no functional changes as part of this update.

When BIOS disables turbo, The scaling_max_freq in cpufreq sysfs will be
limited to config level 0 base frequency. But when user selects a higher
config levels, this will result in higher base frequency. But since
scaling_max_freq is still old base frequency, the performance will still
be limited. So when the turbo is disabled and cpufreq base_frequency is
higher than scaling_max_freq, update the scaling_max_freq to the
base_frequency.

Some older kernels will not have support to get CPU die_id from the
sysfs. This requires several back ports. But the tool depends on getting
die_id to match to correct CPU.
Relax this restriction and use die_id as 0 when die_id is missing. This
is not a problem as we don't have any multi-die processors with Intel SST
support.
This helps in running this tool on older kernels with just Intel SST
drivers back ported.

When SST-PP feature is not present, the TRL (Turbo Ratio Limits)
is read from MSRs. This is done as the mailbox command will fail
on Skylake-X based platform. But for IceLake servers, mailbox
commands can still be used. So add a check to allow for non Skylake
based platforms to read from mail box commands.

This change makes it easier to keep track of offline cpus whose cpuidle
or cpufreq property aren't changed when updates are made to online cpus."
* tag 'linux-cpupower-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux:
cpupower: Provide online and offline CPU information
- if wakeups occur in s2idle: "freeze time: N (-x ms waking y times) ms"
- change FREEZELOOP and FREEZEWAKE to S2LOOP and S2WAKE for brevity
- returns all sysfs vals to their initial state after testing
- use the dmesg log for debugging until the test is completed,
instrument the executeSuspend process to have a full trace,
if test completes, formal dmesg log overwrites the debug log
- fix CPU_ON and CPU_OFF devices in the timeline, should include [n]

... instead of poking at the MSR. For that, move the accessor functions
to misc.c and add a sysfs-writing function too.
There should be no functional changes resulting from this.

====================
pull-request: bpf-next 2020-11-14
1) Add BTF generation for kernel modules and extend BTF infra in kernel
e.g. support for split BTF loading and validation, from Andrii Nakryiko.
2) Support for pointers beyond pkt_end to recognize LLVM generated patterns
on inlined branch conditions, from Alexei Starovoitov.
3) Implements bpf_local_storage for task_struct for BPF LSM, from KP Singh.
4) Enable FENTRY/FEXIT/RAW_TP tracing program to use the bpf_sk_storage
infra, from Martin KaFai Lau.
5) Add XDP bulk APIs that introduce a defer/flush mechanism to optimize the
XDP_REDIRECT path, from Lorenzo Bianconi.
6) Fix a potential (although rather theoretical) deadlock of hashtab in NMI
context, from Song Liu.
7) Fixes for cross and out-of-tree build of bpftool and runqslower allowing build
for different target archs on same source tree, from Jean-Philippe Brucker.
8) Fix error path in htab_map_alloc() triggered from syzbot, from Eric Dumazet.
9) Move functionality from test_tcpbpf_user into the test_progs framework so it
can run in BPF CI, from Alexander Duyck.
10) Lift hashtab key_size limit to be larger than MAX_BPF_STACK, from Florian Lehner.
Note that for the fix from Song we have seen a sparse report on context
imbalance which requires changes in sparse itself for proper annotation
detection where this is currently being discussed on linux-sparse among
developers [0]. Once we have more clarification/guidance after their fix,
Song will follow-up.

Pull turbostat updates from Len Brown:
"Update update to version 20.09.30, one kernel side fix"
* 'turbostat' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux:
tools/power turbostat: update version number
powercap: restrict energy meter to root access
tools/power turbostat: harden against cpu hotplug

tools/power turbostat: Use sched_getcpu() instead of hardcoded cpu 0
tools/power turbostat: Enable accumulate RAPL display

tools/power turbostat: Make the energy variable to be 64 bit
tools/power turbostat: Always print idle in the system configuration header
tools/power turbostat: Print /dev/cpu_dma_latency
When a user tries to modify cpuidle or cpufreq properties on offline
CPUs, the tool returns success (exit status 0) but also does not provide
any warning message regarding offline cpus that may have been specified
but left unchanged. In case of all or a few CPUs being offline, it can be
difficult to keep track of which CPUs didn't get the new frequency or idle
state set. Silent failures are difficult to keep track of when there are a
huge number of CPUs on which the action is performed.
This patch adds helper functions to find both online and offline CPUs and
print them out accordingly.
We use these helper functions in cpuidle-set and cpufreq-set to print an
additional message if the user attempts to modify offline cpus.

turbostat tends to get confused when CPUs are added and removed
while it is running.
There are races, such as checking the current cpu, and then
reading a sysfs file that depends on that cpu number.
Close the two issues that seem to come up the most.
First, there is an infinite reset loop detector --
change that to allow more resets before giving up.
Secondly, one of those file reads didn't really need
to exit the program on failure...

The reported base-freq high-priority-cpu-list was potentially omitting
some cpus, due to incorrectly using a logical core count to constrain
the size of a physical punit core ID mask. We may need to read both high
and low PBF CORE_MASK values regardless of the logical core count.

For compatibility reasons, Glibc off_t is a 32-bit type on 32-bit x86
unless _FILE_OFFSET_BITS=64 is defined. Add this define, as otherwise
reading MSRs with index 0x80000000 and above attempts a pread with a
negative offset, which fails.

Family 19h processors have the same RAPL (Running average power limit)
hardware register interface as Family 17h processors.
Change the family checks to succeed for Family 17h and above to enable
core and package energy measurement on Family 19h machines.
Also update the TDP to the largest found at the bottom of the page at
amd.com->processors->servers->epyc->2nd-gen-epyc, i.e., the EPYC 7H12.

The column already present called GFXMHz reads from gt_cur_freq_mhz,
which represents the GT frequency that was requested, but power
management might not be able to do that. So the new column will display
what the actual frequency GT is running at.

I've encountered an issue with x86_energy_perf_policy. If I run it on a
machine that I'm told is a qemu-kvm virtual machine running inside a
privileged container, I get the following error:
x86_energy_perf_policy: /dev/cpu/0/msr offset 0x1ad read failed: Input/output error
I get the same error in a Digital Ocean droplet, so that might be a
similar environment.
I created the following patch which is intended to give a more
user-friendly message. It's based on a patch for turbostat from Prarit
Bhargava that was posted some time ago. The patch is "[v2] turbostat:
Running on virtual machine is not supported" [1].
Given my limited knowledge of the topic, I can't say with confidence
that this is the right solution, though (that's why this is not an
official patch submission). Also, I'm not sure what the convention with
exit codes is in this tool. Also, instead of the error message, perhaps
the tool should just not print anything in this case, which is how it
behaves in a "regular" VM?

Like we skip PC3 and PC6 columns when the package C-state limit
disables them, skip PC8/PC9/CP10 under analogous conditions.

turbostat formatting is broken with ACPI CST for enumeration. The
problem is that the CX_ACPI% is eight characters long which does not
work with tab formatting. One simple solution is to remove the underbar
from the state name such that C1_ACPI will be displayed as C1ACPI.
