The current notifiers have the following error handling pattern all
over the place:
int err, nr;
err = __foo_notifier_call_chain(&chain, val_up, v, -1, &nr);
if (err & NOTIFIER_STOP_MASK)
__foo_notifier_call_chain(&chain, val_down, v, nr-1, NULL)
And aside from the endless repetition thereof, it is broken. Consider
blocking notifiers; both calls take and drop the rwsem, this means
that the notifier list can change in between the two calls, making @nr
meaningless.
Fix this by replacing all the __foo_notifier_call_chain() functions
with foo_notifier_call_chain_robust() that embeds the above pattern,
but ensures it is inside a single lock region.
Note: I switched atomic_notifier_call_chain_robust() to use
the spinlock, since RCU cannot provide the guarantee
required for the recovery.
Note: software_resume() error handling was broken afaict.

The variable VERSION is expanded for every use of CFLAGS. This causes
"git describe" to get called multiple times on the kernel tree, which
can be quite slow.
The git revision does not change during build, so we can use simple
variable expansion to set VERSION.

Pull power management updates from Rafael Wysocki:
"The most significant change here is the extension of the Energy Model
to cover non-CPU devices (as well as CPUs) from Lukasz Luba.
There is also some new hardware support (Ice Lake server idle states
table for intel_idle, Sapphire Rapids and Power Limit 4 support in the

new switch to disable/enable CPU energy-efficiency optimizations in
intel_pstate, delayed timers in devfreq), some assorted fixes (cpufreq
core, intel_pstate, intel_idle) and cleanups (eg. cpuidle-psci,

Important fixes:
- in s2idle, use timekeeping_freeze trace mark instead of
machine_suspend to denote entry into s2idle mode.
- in s2idle, use machine_suspend trace mark to create a new virtual
device called "s2idle_enter_<n>x". It denotes an s2idle_enter call
loop of <n> iterations where s2idle was never actually achieved.
It isn't counted as "freeze time" in the header.
- in s2idle, only show multiple freeze times if s2idle went in and
out of resume_noirq. Otherwise multiple freezes are shown with
"waking" time subtracted (waking time is time spent outside s2idle
dealing with wakeups).
- in s2idle summaries, include "FREEZEWAKE" as an issue when at
least 1ms is spent waking from s2idle. A clean run should only
wake for the rtc timer.
- add support for device callbacks with matching names in the same
phase. In rare cases some devices register multiple callbacks from
separate drivers using the same name. Without this fix only one is
shown.
- add kparamsfmt string back to fix bootgraph
General updates:
- when suspend_machine is missing, error says "failed in
suspend_machine"
- extract target count/time and add to summary title if -multi
used
- include any instances of "timeout" in dmesg as issues to be
logged.
- fix ftrace parse to handle any number of flags (instead of
just 4).
- remove sync/async_device string from device detail, remains in
hover.
- when using callgraph (-f) add driver name to callgraph titles.

Pull power management updates from Rafael Wysocki:
"These rework the system-wide PM driver flags, make runtime switching
of cpuidle governors easier, improve the user space hibernation
interface code, add intel-speed-select interface documentation, add
more debug messages to the ACPI code handling suspend to idle, update
the cpufreq core and drivers, fix a minor issue in the cpuidle core
and update two cpuidle drivers, improve the PM-runtime framework,
update the Intel RAPL power capping driver, update devfreq core and
drivers, and clean up the cpupower utility.
Specifics:
- Rework the system-wide PM driver flags to make them easier to
understand and use and update their documentation (Rafael Wysocki,
Alan Stern).
- Allow cpuidle governors to be switched at run time regardless of
the kernel configuration and update the related documentation
accordingly (Hanjun Guo).
- Improve the resume device handling in the user space hibernarion
interface code (Domenico Andreoli).
- Document the intel-speed-select sysfs interface (Srinivas
Pandruvada).
- Make the ACPI code handing suspend to idle print more debug
messages to help diagnose issues with it (Rafael Wysocki).
- Fix a helper routine in the cpufreq core and correct a typo in the
struct cpufreq_driver kerneldoc comment (Rafael Wysocki, Wang
Wenhu).
- Update cpufreq drivers:
- Make the intel_pstate driver start in the passive mode by
default on systems without HWP (Rafael Wysocki).
- Add i.MX7ULP support to the imx-cpufreq-dt driver and add
i.MX7ULP to the cpufreq-dt-platdev blacklist (Peng Fan).
- Convert the qoriq cpufreq driver to a platform one, make the
platform code create a suitable device object for it and add
platform dependencies to it (Mian Yousaf Kaukab, Geert
Uytterhoeven).
- Fix wrong compatible binding in the qcom driver (Ansuel Smith).
- Build the omap driver by default for ARCH_OMAP2PLUS (Anders
Roxell).
- Add r8a7742 SoC support to the dt cpufreq driver (Lad
Prabhakar).
- Update cpuidle core and drivers:
- Fix three reference count leaks in error code paths in the
cpuidle core (Qiushi Wu).
- Convert Qualcomm SPM to a generic cpuidle driver (Stephan
Gerhold).
- Fix up the execution order when entering a domain idle state in
the PSCI driver (Ulf Hansson).
- Fix a reference counting issue related to clock management and
clean up two oddities in the PM-runtime framework (Rafael Wysocki,
Andy Shevchenko).
- Add ElkhartLake support to the Intel RAPL power capping driver and
remove an unused local MSR definition from it (Jacob Pan, Sumeet
Pawnikar).
- Update devfreq core and drivers:
- Replace strncpy() with strscpy() in the devfreq core and use
lockdep asserts instead of manual checks for a locked mutex in
it (Dmitry Osipenko, Krzysztof Kozlowski).
- Add a generic imx bus scaling driver and make it register an
interconnect device (Leonard Crestez, Gustavo A. R. Silva).
- Make the cpufreq notifier in the tegra30 driver take boosting
into account and delete an unuseful error message from that
driver (Dmitry Osipenko, Markus Elfring).
- Remove unneeded semicolon from the cpupower code (Zou Wei)"

The core mask display is wrong in some cases. This is showing more
cpus than the mask has. This is because mask is 64 bit but it used
with BIT() macro to get the presence of CPU which doesn't support
unsigned long long. Added a new macro for BIT_ULL and use that
to get the presence of a CPU.

Increase CPU count so that more than 64 is supported in one request.
For example:
sudo ./intel-speed-select -d --cpu 0-66 core-power assoc -clos 0
The above command stops at 63. With this change, it can support more
CPU numbers from 0-255.

The 'intel-speed-select -f json perf-profile get-lock-status' command
outputs the package, die, and cpu data as separate fields.
ex)
"package-0": {
"die-0": {
"cpu-0": {
Commit 74062363f8 ("tools/power/x86/intel-speed-select: Avoid duplicate Package strings for json") prettied this output so that it is a single line for
some json output commands and the same should be done for other commands.
Output package, die, and cpu info in a single line when using json output.

turbo-freq enable, requires clos enable. So this is a two step process,
when "-a" option is used. This is causing confusion to users. So enable
clos by default for turbo-freq enable.

On CLX-N, the perf-profile-level's output is terminated before the
speed-select-base-freq-properties are output which results in a corrupt
json file.

On CLX-N the perf-profile output is missing the package, die, and cpu
output. On CLX-N the pkg_dev struct will never be evaluated by the core
code so pkg_dev.processed is always 0 and the package, die, and cpu
information is never output.
Set the pkg_dev.processed flag to 1 for CLX-N processors.

When turbo-freq or base-freq feature is not supported, the enable will
fail. So first check support status and print error.
Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>
When turbo-freq is enabled, we can't disable core-power. Currently
it prints debug message to warn. Change this to error message.
While here remove "\n" from calls to isst_display_error_info_message(),
as it will be added again during actual print.

The single user could have called freeze_secondary_cpus() directly.
Since this function was a source of confusion, remove it as it's
just a pointless wrapper.
While at it, rename enable_nonboot_cpus() to thaw_secondary_cpus() to
preserve the naming symmetry.

Here are 3 SPDX patches for 5.7-rc1.
One fixes up the SPDX tag for a single driver, while the other two go
through the tree and add SPDX tags for all of the .gitignore files as
needed.
Nothing too complex, but you will get a merge conflict with your current
tree, that should be trivial to handle (one file modified by two things,
one file deleted.)
All 3 of these have been in linux-next for a while, with no reported
issues other than the merge conflict.

For platforms where multiple packages/die, this makes "Package-" key
duplicate. To make unique, add die and cpu id to key name.
So "Package-0" key name will change to "Package-0-die-x:cpu-x".
For example:
$sudo ./intel-speed-select -f json perf-profile info
Intel(R) Speed Select Technology
Executing on CPU model:106[0x6a]
{
"package-0:die-0:cpu-0": {
"perf-profile-level-0": {
"cpu-count": "32",
"enable-cpu-count": "32",
...
...
"package-1:die-0:cpu-16": {
"perf-profile-level-0": {
"cpu-count": "32",
"enable-cpu-count": "32",
"enable-cpu-mask": "ffff0000,ffff0000",
...
...
For non json format, there is no change. Here when print_package_info()
is called, it will return the level to print for other information.
This level is used formatting. Also in some function duplicate code
was there to print package,die and CPU information. Replace all that
code with a call to print_package_info().

Treat a case when mailbox/mmio command can't be handled by the kernel
drivers when the module is removed or send a command which no driver can
handle. In this case ENOTTY result is returned, so print error.
Also when the isst_if_mmio module is removed, we can't send CLOS message
messages via Mailbox on non SKX based platforms. When this module is
removed, isst_platform_info.mmio_supported is set to 0. So it can't be
used as a condition to send via mailbox. Here replace check for Skylake

Once the CPU is offline, the topology information (core-id, package-id,
die-id) is not accessible via sysfs. So when user selects a config level
more than base config 0 and offlined CPUs to match the config level,
to return to base config he has to manually online CPUs before. Without
this CPUs information mapping from Punit CPU numbering will lot work
as it needs atlest package id for each CPU.
To avoid this additional steps store the topology information in a file
, which is created on the very first run after boot. Since system boots
in base config and all CPUs are online, we can get information about
every CPU.
Once any of the APIs like get_physical_package_id(),
get_physical_core_id() or get_physical_die_id() fails to read from
sysfs, read from the stored mapping file.
This mapping file is stored in /tmp file system. so on every boot
it is recreated to make sure that any new CPUs are added to the
system before boot are taken into account.
But don't use the stored physical device id when trying to get
information for CPU to send message in for_each_online_package_in_set().
Here use the real value from syfs and in case fails try the next CPU.

Instead of displaying 0 and 1 for enable status, display "disabled"

package-0
die-0
cpu-0
core-power
support-status:supported
enable-status:enabled

For the command

There are two instances of “speed-select-turbo-freq” underneath
“perf-profile-level-0” for each package. When we load the output into
python with json.load(), the second instance overwrites the first.
Result is that we can only access:
"speed-select-turbo-freq": {
"bucket-0": {
"high-priority-cores-count": "2",
"high-priority-max-frequency(MHz)": "3000",
"high-priority-max-avx2-frequency(MHz)": "2800",

Because it is a duplicate of "speed-select-turbo-freq": "disabled"

The turbo-freq enable with auto mode, prints result for the last possible
CPU, which is not correct when either CPU is not present or user wants
command to be limited to a single die/package. For example, in the
below command user wants to limit to die/package 0, but the
"turbo-freq --auto" result is displayed using the other package.
$ sudo intel-speed-select -c 0 turbo-freq enable -a
Intel(R) Speed Select Technology
package-0
die-0
cpu-0
turbo-freq
enable:success
package--1
die-0
cpu-31
turbo-freq --auto
enable:success
Since we do have to traverse all CPUs, don't display CPU info for
"turbo-freq --auto", as we already displayed the result for
turbo-freq enable with the CPU information.
With the fix, the same command results in:
$ sudo intel-speed-select -c 0 turbo-freq enable -a

*cpufreq_get_available_frequencies(unsigned int cpu)
to
struct cpufreq_frequencies
*cpufreq_get_frequencies(const char *type, unsigned int cpu)
This patch recovers the old API and implements the new functionality
in a newly introduce method:
struct cpufreq_boost_frequencies
*cpufreq_get_available_frequencies(unsigned int cpu)
This one should get merged into stable kernels back to 5.0 when

Sync msr-index.h to pull in recent renames of the IA32_FEATURE_CONTROL
MSR definitions. Update KVM's VMX selftest and turbostat accordingly.
Keep the full name in turbostat's output to avoid breaking someone's
workflow, e.g. if a script is looking for the full name.
While using the renamed defines is by no means necessary, do the sync
now to avoid leaving a landmine that will get stepped on the next time
msr-index.h needs to be refreshed for some other reason.

It is possible that certain config levels are not available, even
if the max level includes the level. There can be missing levels in
some platforms. So ignore the level when called for information dump
for all levels and fail if specifically ask for the missing level.
Here the changes is to continue reading information about other levels
even if we fail to get information for the current level. But use the
"processed" flag to indicate the failure. When the "processed" flag is
not set, don't dump information about that level.

There are some platforms, where there limited support of Intel(R) SST
features. Here perf-profile has only one base configuration and limited
support of commands. But still has support for discovery of base-freq and
turbo-freq features. So it is important to show minimum features to use
base-freq and turbo-freq features.
Here the change are:
- When there is no support of CONFIG_TDP_GET_LEVELS_INFO, then instead
of treating this as fatal error, treat this with number of config levels
= 0, that means only base level 0 is present.
- There is no support of mail box commands to get base frequencies or
turbo frequencies. Here present base frequency by reading cpufreq
base freq and turbo frequency by reading MSR 0x1AD.
- Don't display any field, which has value == 0.

Scaling min frequency be different for high and low priority cores.
This is the way the firmware will understand the priority.

scaling_min_freq to P1High for high priority cores and P1Low to low
priority cores.

In CLX_N base_frequency is read from cpufreq sysfs, where units are in
KHz. The internal units in the code matches the real ratios which are
in 100MHz scale. So when storing units for CLX-N frequencies, convert
to 100MHz scale.

AMD Zen 2 introduces the RDPRU instruction which can be used to access some
processor registers which are typically only accessible in privilege level
0. ECX specifies the register to read and EDX:EAX will contain the value read.
ECX: 0 - Register MPERF
1 - Register APERF
This has the added advantage of not having to use the msr module, since the
userspace to kernel transitions which occur during each read_msr() might
cause APERF and MPERF to go out of sync.

The per_cpu_schedule flag is used to move the cpupower process to the cpu
on which we are looking to read the APERF/MPERF registers.
This prevents IPIs from being generated by read_msr()s as we are already
on the cpu of interest.
Ex: If cpupower is running on CPU 0 and we execute
read_msr(20, MSR_APERF, val) then,
read_msr(20, MSR_MPERF, val)
the msr module will generate an IPI from CPU 0 to CPU 20 to query
for the MSR_APERF and then the MSR_MPERF in separate IPIs.
This delay, caused by IPI latency, between reading the APERF and MPERF
registers may cause both of them to go out of sync.
The use of the per_cpu_schedule flag reduces the probability of this
from happening. It comes at the cost of a negligible increase in cpu
consumption caused by the migration of cpupower across each of the
cpus of the system.

Cpupower tool has set and info options which are being used only by
x86 machines. This patch removes support for these two subcommands
from cpupower utility for POWER. Thus, these two subcommands will now be
available only for intel.
This removes the ambiguous error message while using set option in case
of using non-intel systems.
Without this patch on a POWER system:

The turbo-freq feature is dependent on the core-power feature. If the
core-power feature is disabled while the turbo-freq feature is enabled,
this will break the turbo-freq feature. This is a firmware limitation,

So when trying to disable core-power, make sure that the turbo-freq
feature is not enabled. If it enabled, return error if user is trying to

Introduce --auto|-a option to turbo-freq enable feature, so that it
does in one step for users who are OK by setting all passed target cores
as high priority and set in CLOS 0 and remaining in CLOS 3. In this way,
users don't have to take multiple steps to enable turbo-freq feature. For
users who want more fine grain control, they can always use core-power
feature to set custom CLOS configuration and assignment.
While here also print the error to output when clos configuration fails.
For example
intel-speed-select -c 0-4 turbo-freq enable --auto
The above command will enable turbo-freq and core-power feature. Also

commit "c016ae8f9fa04d361efc8629de49ad3af12b5262
"tools/power/x86/intel-speed-select: Output success/failed for command

For example before this commit the display was:

Here the get-config-levels is interpreted as error and displayed
as error with the above commit:
package-1

Pull power management updates from Rafael Wysocki:
"These include a rework of the main suspend-to-idle code flow (related
to the handling of spurious wakeups), a switch over of several users
of cpufreq notifiers to QoS-based limits, a new devfreq driver for
Tegra20, a new cpuidle driver and governor for virtualized guests, an
extension of the wakeup sources framework to expose wakeup sources as
device objects in sysfs, and more.
Specifics:
- Rework the main suspend-to-idle control flow to avoid repeating
"noirq" device resume and suspend operations in case of spurious
wakeups from the ACPI EC and decouple the ACPI EC wakeups support
from the LPS0 _DSM support (Rafael Wysocki).
- Extend the wakeup sources framework to expose wakeup sources as
device objects in sysfs (Tri Vo, Stephen Boyd).
- Expose system suspend statistics in sysfs (Kalesh Singh).
- Introduce a new haltpoll cpuidle driver and a new matching governor
for virtualized guests wanting to do guest-side polling in the idle
loop (Marcelo Tosatti, Joao Martins, Wanpeng Li, Stephen Rothwell).
- Fix the menu and teo cpuidle governors to allow the scheduler tick
to be stopped if PM QoS is used to limit the CPU idle state exit
latency in some cases (Rafael Wysocki).
- Increase the resolution of the play_idle() argument to microseconds
for more fine-grained injection of CPU idle cycles (Daniel
Lezcano).
- Switch over some users of cpuidle notifiers to the new QoS-based
frequency limits and drop the CPUFREQ_ADJUST and CPUFREQ_NOTIFY
policy notifier events (Viresh Kumar).
- Add new cpufreq driver based on nvmem for sun50i (Yangtao Li).
- Add support for MT8183 and MT8516 to the mediatek cpufreq driver
(Andrew-sh.Cheng, Fabien Parent).
- Add i.MX8MN support to the imx-cpufreq-dt cpufreq driver (Anson
Huang).
- Add qcs404 to cpufreq-dt-platdev blacklist (Jorge Ramirez-Ortiz).
- Update the qcom cpufreq driver (among other things, to make it
easier to extend and to use kryo cpufreq for other nvmem-based
SoCs) and add qcs404 support to it (Niklas Cassel, Douglas
RAILLARD, Sibi Sankar, Sricharan R).
- Fix assorted issues and make assorted minor improvements in the
cpufreq code (Colin Ian King, Douglas RAILLARD, Florian Fainelli,
Gustavo Silva, Hariprasad Kelam).
- Add new devfreq driver for NVidia Tegra20 (Dmitry Osipenko, Arnd
Bergmann).
- Add new Exynos PPMU events to devfreq events and extend that
mechanism (Lukasz Luba).
- Fix and clean up the exynos-bus devfreq driver (Kamil Konieczny).
- Improve devfreq documentation and governor code, fix spelling typos
in devfreq (Ezequiel Garcia, Krzysztof Kozlowski, Leonard Crestez,
MyungJoo Ham, Gaël PORTAY).
- Add regulators enable and disable to the OPP (operating performance
points) framework (Kamil Konieczny).
- Update the OPP framework to support multiple opp-suspend properties
(Anson Huang).
- Fix assorted issues and make assorted minor improvements in the OPP
code (Niklas Cassel, Viresh Kumar, Yue Hu).
- Clean up the generic power domains (genpd) framework (Ulf Hansson).
- Clean up assorted pieces of power management code and documentation
(Akinobu Mita, Amit Kucheria, Chuhong Yuan).
- Update the pm-graph tool to version 5.5 including multiple fixes
and improvements (Todd Brandt).
- Update the cpupower utility (Benjamin Weis, Geert Uytterhoeven,
Sébastien Szymanski)"
