commit 2685c77b80a80c57e2a25a726b82fb31e6e212ab upstream.
The existing mail mechanism only supports writing of workload types.
However, mailbox command for RFIM (cmd = 0x08) also requires write
operation which is ignored. This results in failing to store RFI
restriction.
Fixint this requires enhancing mailbox writes for non workload
commands too, so remove the check for MBOX_CMD_WORKLOAD_TYPE_WRITE
in mailbox write to allow this other write commands to be supoorted.
At the same time, however, we have to make sure that there is no
impact on read commands, by avoiding to write anything into the
mailbox data register.
To properly implement that, add two separate functions for mbox read
and write commands for the processor thermal workload command type.
This helps to distinguish the read and write workload command types
from each other while sending mbox commands.

commit 994a04a20b03128838ec0250a0e266aab24d23f1 upstream.
32-bit processors cannot generally access 64-bit MMIO registers
atomically, and it is unknown in which order the two halves of
this registers would need to be read:
drivers/thermal/intel/int340x_thermal/processor_thermal_mbox.c: In function 'send_mbox_cmd':
drivers/thermal/intel/int340x_thermal/processor_thermal_mbox.c:79:37: error: implicit declaration of function 'readq'; did you mean 'readl'? [-Werror=implicit-function-declaration]
79 | *cmd_resp = readq((void __iomem *) (proc_priv->mmio_base + MBOX_OFFSET_DATA));
| ^~~~~
| readl
The driver already does not build for anything other than x86,
so limit it further to x86-64.

commit c4fcf1ada4ae63e0aab6afd19ca2e7d16833302c upstream.
When the driver resumes, the tcc offset is set back to its previous
value. But this only works if the value was user defined as otherwise
the offset isn't saved. This asymmetric logic is harder to maintain and
introduced some issues.
Improve the logic by saving the tcc offset in a suspend op, so the right
value is always restored after a resume.

[ Upstream commit d9c8e52ff9e84ff1a406330f9ea4de7c5eb40282 ]
Commit aeb58c860dc5 ("thermal/drivers/int340x: processor_thermal: Suppot
64 bit RFIM responses") started using 'readq()' to read 64-bit status
responses from the int340x hardware.
That's all fine and good, but on 32-bit targets a 64-bit 'readq()' is
ambiguous, since it's no longer an atomic access. Some hardware might
require 64-bit accesses, and other hardware might want low word first or
high word first.
It's quite likely that the driver isn't relevant in a 32-bit environment
any more, and there's a patch floating around to just make it depend on
X86_64, but let's make it buildable on x86-32 anyway.
The driver previously just read the low 32 bits, so the hardware
certainly is ok with 32-bit reads, and in a little-endian environment
the low word first model is the natural one.
So just add the include for the 'io-64-nonatomic-lo-hi.h' version.

After upgrading to Linux 5.13.3 I noticed my laptop would shutdown due
to overheat (when it should not). It turned out this was due to commit
fe6a6de6692e ("thermal/drivers/int340x/processor_thermal: Fix tcc setting").
What happens is this drivers uses a global variable to keep track of the
tcc offset (tcc_offset_save) and uses it on resume. The issue is this
variable is initialized to 0, but is only set in
tcc_offset_degree_celsius_store, i.e. when the tcc offset is explicitly
set by userspace. If that does not happen, the resume path will set the
offset to 0 (in my case the h/w default being 3, the offset would become
too low after a suspend/resume cycle).
The issue did not arise before commit fe6a6de6692e, as the function
setting the offset would return if the offset was 0. This is no longer
the case (rightfully).
Fix this by not applying the offset if it wasn't saved before, reverting
back to the old logic. A better approach will come later, but this will
be easier to apply to stable kernels.
The logic to restore the offset after a resume was there long before
commit fe6a6de6692e, but as a value of 0 was considered invalid I'm
referencing the commit that made the issue possible in the Fixes tag
instead.

Add a new PCI driver which register a thermal zone and allows to get
notification for threshold violation by a RW trip point. These
notifications are delivered from the device using MSI based
interrupt.
The main difference between this new PCI driver and the existing
one is that the temperature and trip points directly use PCI
MMIO instead of using ACPI methods.
This driver registers a thermal zone "TCPU_PCI" in addition to the
legacy processor thermal device, which uses ACPI companion device
to set name, temperature and trips.
This driver is enabled for AlderLake.

Remove enumeration part from the processor_thermal_device to two
different modules. One for ACPI and one for PCI:
ACPI enumeration: int3401_thermal
PCI part: processor_thermal_device_pci_legacy
The current processor_thermal_device now just implements interface
functions to be used by the ACPI and PCI enumeration module. This is
done by:
1. Make functions proc_thermal_add() and proc_thermal_remove() non static
and export them for usage in other processor_thermal_device_pci_legacy.c
and in int3401_thermal.c.
2. Move the sysfs file creation for TCC offset and power limit attribute
group to the proc_thermal_add() from the individual enumeration callbacks
for PCI and ACPI.
3. Create new interface functions proc_thermal_mmio_add() and
proc_thermal_mmio_remove() which will be called from the
processor_thermal_device_pci_legacy module.
4. Export proc_thermal_resume(), so that it can be used by power
management callbacks.
5. Remove special check for double enumeration as it never happens.
While here, fix some cleanup on error conditions in proc_thermal_add().
No functional changes are expected with this change.

After commit 81ad4276b505 ("Thermal: Ignore invalid trip points") all
user_space governor notifications via RW trip point is broken in intel
thermal drivers. This commits marks trip_points with value of 0 during
call to thermal_zone_device_register() as invalid. RW trip points can be
0 as user space will set the correct trip temperature later.
During driver init, x86_package_temp and all int340x drivers sets RW trip
temperature as 0. This results in all these trips marked as invalid by
the thermal core.
To fix this initialize RW trips to THERMAL_TEMP_INVALID instead of 0.

We are seeing thermal shutdown on Intel based mobile workstations, the
shutdown happens during the first trip handle in
thermal_zone_device_register():
kernel: thermal thermal_zone15: critical temperature reached (101 C), shutting down
However, we shouldn't do a thermal shutdown here, since
1) We may want to use a dedicated daemon, Intel's thermald in this case,
to handle thermal shutdown.
2) For ACPI based system, _CRT doesn't mean shutdown unless it's inside
ThermalZone namespace. ACPI Spec, 11.4.4 _CRT (Critical Temperature):
"... If this object it present under a device, the device’s driver
evaluates this object to determine the device’s critical cooling
temperature trip point. This value may then be used by the device’s
driver to program an internal device temperature sensor trip point."
So a "critical trip" here merely means we should take a more aggressive
cooling method.
As int340x device isn't present under ACPI ThermalZone, override the
default .critical callback to prevent surprising thermal shutdown.

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
ddr_data_rate_point_3 (RO): DDR data rate selection 4th 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

set_mode() is only called when tzd's mode is about to change. Actual
setting is performed in thermal_core, in thermal_zone_device_set_mode().
The meaning of set_mode() callback is actually to notify the driver about
the mode being changed and giving the driver a chance to oppose such
change.
To better reflect the purpose of the method rename it to change_mode()

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
