- Update the Energy Model support code to allow the Energy Model to be
artificial, which means that the power values may not be on a uniform
scale with other devices providing power information, and update the
cpufreq_cooling and devfreq_cooling thermal drivers to support
artificial Energy Models (Lukasz Luba).
- Make DTPM check the Energy Model type (Lukasz Luba).
- Fix policy counter decrementation in cpufreq if Energy Model is in
use (Pierre Gondois).
- Add AlderLake processor support to the intel_idle driver (Zhang Rui).
- Fix regression leading to no genpd governor in the PSCI cpuidle
driver and fix the riscv-sbi cpuidle driver to allow a genpd
governor to be used (Ulf Hansson).
* pm-em:
PM: EM: Decrement policy counter
powercap: DTPM: Check for Energy Model type
thermal: cooling: Check Energy Model type in cpufreq_cooling and devfreq_cooling
Documentation: EM: Add artificial EM registration description
PM: EM: Remove old debugfs files and print all 'flags'
PM: EM: Change the order of arguments in the .active_power() callback
PM: EM: Use the new .get_cost() callback while registering EM
PM: EM: Add artificial EM flag

cpuidle: psci: Fix regression leading to no genpd governor
intel_idle: Add AlderLake support
The thermal subsystem registers a hwmon device without providing chip
information or sysfs attribute groups. While undesirable, it would be
difficult to change. On the other side, it abuses the
hwmon_device_register_with_info API by not providing that information.
Use new API specifically created for the thermal subsystem instead to
let us enforce the 'chip' parameter for other callers of

Previously, during suspend, intel_pch_thermal driver logs for every
cooling iteration, about the current PCH temperature and number of cooling
iterations that have been tried, like below
[ 100.955526] intel_pch_thermal 0000:00:14.2: CPU-PCH current temp [53C] higher than the threshold temp [50C], sleep 1 times for 100 ms duration
[ 101.064156] intel_pch_thermal 0000:00:14.2: CPU-PCH current temp [53C] higher than the threshold temp [50C], sleep 2 times for 100 ms duration
After changing the default delay_cnt to 600, in practice, it is common to
see tens of the above messages if the system is suspended when PCH
overheats. Thus, change this log message from dev_warn to dev_dbg because
it is only useful when we want to check the temperature trend.
At the same time, there is always a one-line message given by the driver
with the patch applied, with below four possibilities.
1. PCH is cool, no cooling delay needed
[ 1791.902853] intel_pch_thermal 0000:00:12.0: CPU-PCH is cool [48C]
2. PCH overheats and becomes cool after the cooling delays
[ 1475.511617] intel_pch_thermal 0000:00:12.0: CPU-PCH is cool [49C] after 30700 ms delay
3. PCH still overheats after the overall cooling timeout
[ 2250.157487] intel_pch_thermal 0000:00:12.0: CPU-PCH is hot [60C] after 60000 ms delay. S0ix might fail
4. PCH aborts cooling because of wakeup event detected during the delay
[ 1933.639509] intel_pch_thermal 0000:00:12.0: Wakeup event detected, abort cooling

Commit ef63b043ac ("thermal: intel: pch: fix S0ix failure due to PCH
temperature above threshold") introduces delay loop mechanism that allows
PCH temperature to go down below threshold during suspend so it won't
block S0ix. And the default overall delay timeout is 1 second.
However, in practice, we found that the time it takes to cool the PCH down
below threshold highly depends on the initial PCH temperature when the
delay starts, as well as the ambient temperature.
And in some cases, the 1 second delay is not sufficient. As a result, the
system stays in a shallower power state like PCx instead of S0ix, and
drains the battery power, without user' notice.
To make sure S0ix is not blocked by the PCH overheating, we
1. expand the default overall timeout to 60 seconds.
2. make sure the temperature is below threshold rather than equal to it.
At the same time, as the cooling delay can be much longer and many wakeup
events (ACPI Power Button press, USB mouse move, etc) becomes valid in the
suspend_noirq phase, add detection of wakeup event so that the driver
does not delay blindly when the system suspend is likely to abort soon.
This patch may introduce longer suspend time, but only in the cases when
the system overheats and Linux used to enter a shallower S2idle state,
say, PCx instead of S0ix.

Add VTM thermal support. In the Voltage Thermal Management
Module(VTM), K3 J72XX supplies a voltage reference and a temperature
sensor feature that are gathered in the band gap voltage and
temperature sensor (VBGAPTS) module. The band gap provides current and
voltage reference for its internal circuits and other analog IP
blocks. The analog-to-digital converter (ADC) produces an output value
that is proportional to the silicon temperature.
Currently reading temperatures only is supported. There are no
active/passive cooling agent supported.
J721e SoCs have errata i2128: https://www.ti.com/lit/pdf/sprz455
The VTM Temperature Monitors (TEMPSENSORs) are trimmed during production,
with the resulting values stored in software-readable registers. Software
should use these register values when translating the Temperature
Monitor output codes to temperature values.
It has an involved workaround. Software needs to read the error codes for
-40C, 30C, 125C from the efuse for each device & derive a new look up table
for adc to temperature conversion. Involved calculating slopes & constants
using 3 different straight line equations with adc refernce codes as the
y-axis & error codes in the x-axis.
-40C to 30C
30C to 125C
125C to 150C
With the above 2 line equations we derive the full look-up table to
workaround the errata i2128 for j721e SoC.
Tested temperature reading on J721e SoC & J7200 SoC.

The "enabled" mode fails with -EINVAL when the new handshake is used.
To address this issue, when the new OS UUID mask is set:
- When the mode is "enabled", return 0 as the firmware already has the
latest policy mask.
- When the mode is "disabled", update the firmware with the UUID mask
of zero.
This way, the firmware can take over the thermal control.

There are multiple devfreq cooling devices in system, some of them has
EM model but others do not. Energy model ops such as state2power will

The IPA governor regards the cooling devices without EM model as a power

Update the firmware with OS supported policies mask, so that firmware can
relinquish its internal controls. Without this update several Tiger Lake
laptops gets performance limited with in few seconds of executing in
turbo region.
The existing way of enumerating firmware policies via IDSP method and
selecting policy by directly writing those policy UUIDS via _OSC method
is not supported in newer generation of hardware.
There is a new UUID "B23BA85D-C8B7-3542-88DE-8DE2FFCFD698" is defined for
updating policy capabilities. As part of ACPI _OSC method:
Arg0 - UUID: B23BA85D-C8B7-3542-88DE-8DE2FFCFD698
Arg1 - Rev ID: 1
Arg2 - Count: 2
Arg3 - Capability buffers: Array of Arg2 DWORDS
DWORD1: As defined in the ACPI 5.0 Specification
- Bit 0: Query Flag
- Bits 1-3: Always 0
- Bits 4-31: Reserved
DWORD2 and beyond:
- Bit0: set to 1 to indicate Intel(R) Dynamic Tuning is active, 0 to
indicate it is disabled and legacy thermal mechanism should
be enabled.
- Bit1: set to 1 to indicate Intel(R) Dynamic Tuning is controlling
active cooling, 0 to indicate bios shall enable legacy thermal
zone with active trip point.
- Bit2: set to 1 to indicate Intel(R) Dynamic Tuning is controlling
passive cooling, 0 to indicate bios shall enable legacy thermal
zone with passive trip point.
- Bit3: set to 1 to indicate Intel(R) Dynamic Tuning is handling
critical trip point, 0 to indicate bios shall enable legacy
thermal zone with critical trip point.
- Bits 4:31: Reserved
From sysfs interface, there is an existing interface to update policy
UUID using attribute "current_uuid". User space can write the same UUID
for ACTIVE, PASSIVE and CRITICAL policy. Driver converts these UUIDs to
DWORD2 Bit 1 to Bit 3. When any of the policy is activated by user
space it is assumed that dynamic tuning is active.
For example
$cd /sys/bus/platform/devices/INTC1040:00/uuids
To support active policy
$echo "3A95C389-E4B8-4629-A526-C52C88626BAE" > current_uuid
To support passive policy
$echo "42A441D6-AE6A-462b-A84B-4A8CE79027D3" > current_uuid
To support critical policy
$echo "97C68AE7-15FA-499c-B8C9-5DA81D606E0A" > current_uuid
To check all the supported policies
$cat current_uuid
3A95C389-E4B8-4629-A526-C52C88626BAE
42A441D6-AE6A-462b-A84B-4A8CE79027D3
97C68AE7-15FA-499c-B8C9-5DA81D606E0A
To match the bit format for DWORD2, rearranged enum int3400_thermal_uuid
and int3400_thermal_uuids[] by swapping current INT3400_THERMAL_ACTIVE
and INT3400_THERMAL_PASSIVE_1.
If the policies are enumerated via IDSP method then legacy method is
used, if not the new method is used to update policy support.
