Added processor thermal device mail box interface for workload hints
setting. These hints will give indication to hardware to better manage
power and thermals. The supported hints are:
idle
semi_active
burusty
sustained
battery_life
For example when the system is on battery, the hardware can be less
aggressive in power ramp up.
This will create an attribute group at
/sys/bus/pci/devices/0000:00:04.0/workload_request
This folder contains two attributes:
workload_available_types : (RO): This shows available workload types
workload_type: (RW) : Allows to set and get current workload type

Add support for RFIM (Radio Frequency Interference Mitigation) support
via processor thermal PCI device. This drivers allows adjustment of
FIVR (Fully Integrated Voltage Regulator) and DDR (Double Data Rate)
frequencies to avoid RF interference with WiFi and 5G.
Switching voltage regulators (VR) generate radiated EMI or RFI at the
fundamental frequency and its harmonics. Some harmonics may interfere
with very sensitive wireless receivers such as Wi-Fi and cellular that
are integrated into host systems like notebook PCs. One of mitigation
methods is requesting SOC integrated VR (IVR) switching frequency to a
small % and shift away the switching noise harmonic interference from
radio channels. OEM or ODMs can use the driver to control SOC IVR
operation within the range where it does not impact IVR performance.
DRAM devices of DDR IO interface and their power plane can generate EMI
at the data rates. Similar to IVR control mechanism, Intel offers a
mechanism by which DDR data rates can be changed if several conditions
are met: there is strong RFI interference because of DDR; CPU power
management has no other restriction in changing DDR data rates;
PC ODMs enable this feature (real time DDR RFI Mitigation referred to as
DDR-RFIM) for Wi-Fi from BIOS.
This change exports two folders under /sys/bus/pci/devices/0000:00:04.0.
One folder "fivr" contains all attributes exposed for controling FIVR
features. The other folder "dvfs" contains all attributes for DDR
features.
Changes done to implement:
- New module for rfim interfaces
- Two new per processor features for DDR and FIVR
- Enable feature for Tiger Lake (FIVR only) and Alder Lake
The attributes exposed and explanation:
FIVR attributes
vco_ref_code_lo (RW): The VCO reference code is an 11-bit field and
controls the FIVR switching frequency. This is the 3-bit LSB field.
vco_ref_code_hi (RW): The VCO reference code is an 11-bit field and
controls the FIVR switching frequency. This is the 8-bit MSB field.
spread_spectrum_pct (RW): Set the FIVR spread spectrum clocking
percentage
spread_spectrum_clk_enable (RW): Enable/disable of the FIVR spread
spectrum clocking feature
rfi_vco_ref_code (RW): This field is a read only status register which
reflects the current FIVR switching frequency
fivr_fffc_rev (RW): This field indicated the revision of the FIVR HW.
DVFS attributes
rfi_restriction_run_busy (RW): Request the restriction of specific DDR
data rate and set this value 1. Self reset to 0 after operation.
rfi_restriction_err_code (RW): Values: 0 :Request is accepted, 1:Feature
disabled, 2: the request restricts more points than it is allowed
rfi_restriction_data_rate_Delta (RW): Restricted DDR data rate for RFI
protection: Lower Limit
rfi_restriction_data_rate_Base (RW): Restricted DDR data rate for RFI
protection: Upper Limit
ddr_data_rate_point_0 (RO): DDR data rate selection 1st point
ddr_data_rate_point_1 (RO): DDR data rate selection 2nd point
ddr_data_rate_point_2 (RO): DDR data rate selection 3rd point

The Processor Thermal PCI device supports multiple features. Currently
we export only RAPL. But we need more features from this device exposed
for Tiger Lake and Alder Lake based platforms. So re-structure the
current MMIO interface, so that more features can be added cleanly.
No functional changes are expected with this change.
Changes done in this patch:
- Using PCI_DEVICE_DATA(), hence names of defines changed
- Move RAPL MMIO code to its own module
- Move the RAPL MMIO offsets to RAPL MMIO module
- Adjust Kconfig dependency of PROC_THERMAL_MMIO_RAPL
- Per processor driver data now contains the supported features
- Moved all the common data structures and defines to a common header
file
- This new header file contains all the processor_thermal_* interfaces
- Based on the features supported the module interface is called
- Each module atleast provides one add and one remove function

I noticed that I couldn't read the PCH temperature on my workstation
(C620 series chipset, w/ 2x Xeon Gold 5215 CPUs) directly, but had to go
through IPMI. Looking at the data sheet, it looks to me like the
existing intel PCH thermal driver should work without changes for
Lewisburg.
I suspect there's some other PCI IDs missing. But I hope somebody at
Intel would have an easier time figuring that out than I...

When system tries to enter S0ix suspend state, just after active load
scenarios, it fails due to PCH current temperature is higher than set
threshold.
This patch introduces delay loop mechanism that allows PCH temperature
to go down below threshold during suspend so it won't fail to enter S0ix.
Add delay loop timeout and count as module parameters for user to tune it,
if required based on system design. This change notifies the different
warning messages like when PCH temperature above the threshold and
executing delay loop. Also, notify the messages when it success or
failure for S0ix entry.
Previously out of 1000 runs around 3 to 5 times it might fail to enter
S0ix just after heavy workload. With this change, S0ix failures reduced
as PCH cools down below threshold.

static priority level knowledge from non-scheduler code.
The three APIs for non-scheduler code to set SCHED_FIFO are:
- sched_set_fifo()
- sched_set_fifo_low()
- sched_set_normal()
These are two FIFO priority levels: default (high), and a 'low' priority level,
plus sched_set_normal() to set the policy back to non-SCHED_FIFO.
Since the changes affect a lot of non-scheduler code, we kept this in a separate

Use thermal_zone_device_{en|dis}able() and thermal_zone_device_is_enabled().
Consequently, all set_mode() implementations in drivers:
- can stop modifying tzd's "mode" member,
- shall stop taking tzd's lock, as it is taken in the helpers
- shall stop calling thermal_zone_device_update() as it is called in the
helpers
- can assume they are called when the mode truly changes, so checks to
verify that can be dropped
Not providing set_mode() by a driver no longer prevents the core from
being able to set tzd's mode, so the relevant check in mode_store() is
removed.
Other comments:
- acpi/thermal.c: tz->thermal_zone->mode will be updated only after we
return from set_mode(), so use function parameter in thermal_set_mode()
instead, no need to call acpi_thermal_check() in set_mode()
- thermal/imx_thermal.c: regmap writes and mode assignment are done in
thermal_zone_device_{en|dis}able() and set_mode() callback
- thermal/intel/intel_quark_dts_thermal.c: soc_dts_{en|dis}able() are a
part of set_mode() callback, so they don't need to modify tzd->mode, and
don't need to fall back to the opposite mode if unsuccessful, as the return
value will be propagated to thermal_zone_device_{en|dis}able() and
ultimately tzd's member will not be changed in thermal_zone_device_set_mode().
- thermal/of-thermal.c: no need to set zone->mode to DISABLED in
of_parse_thermal_zones() as a tzd is kzalloc'ed so mode is DISABLED anyway

The platform vendor may expose an array of OEM-specific values to be used
in determining DPTF policy. These are obtained via the ODVP method, and
then simply exposed in sysfs. In addition, they are updated when a
notification is received or when the DPTF policy is changed by userland.

Implementing DPTF properly requires making use of firmware-provided
information associated with the INT3400 device. Calling GDDV provides a
buffer of information which userland can then interpret to determine
appropriate DPTF policy.

a sleep-able context (Geert Uytterhoeven)
- Do code cleanup and re-organization to set the scene for a new
process for the brcmstb (Florian Fainelli)
- Fix bindings check issues on brcm (Stefan Wahren)
- Add Jasper Lake support on int340x (Nivedita Swaminathan)
- Add Comet Lake support on intel pch (Gayatri Kammela)
- Fix unmatched pci_release_region() on x86 (Chuhong Yuan)
- Remove temperature boundaries for rcar and rcar3 (Niklas Söderlund)
- Fix return value to -ENODEV when thermal_zone_of_sensor_register() is
called with the of-node is missing (Peter Mamonov)

The driver calls pci_request_regions() in probe and uses
pci_release_regions() in probe failure.
However, it calls pci_release_region() in remove, which does
match the other two calls.
Use pci_release_regions() instead to unify them.
