2020-12-10thermal: int340x: processor_thermal: Add mailbox driverSrinivas Pandruvada
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 setting Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://lore.kernel.org/r/20201126171829.945969-4-srinivas.pandruvada@linux.intel.com
2020-12-10thermal: int340x: processor_thermal: Add RFIM driverSrinivas Pandruvada
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 rfi_disable (RW): Disable DDR rate change feature Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://lore.kernel.org/r/20201126171829.945969-3-srinivas.pandruvada@linux.intel.com

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 Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://lore.kernel.org/r/20201126171829.945969-1-srinivas.pandruvada@linux.intel.com

2020-12-07platform/x86/drivers/acerhdf: Check the interval value when it is setDaniel Lezcano
Currently the code checks the interval value when the temperature is read which is bad for two reasons: - checking and setting the interval in the get_temp callback is inaccurate and awful, that can be done when changing the value. - Changing the thermal zone structure internals is an abuse of the exported structure, moreover no lock is taken here. The goal of this patch is to solve the first item by using the 'set' function called when changing the interval. The check is done there and removed from the get_temp function. If the thermal zone was not initialized yet, the interval is not updated in this case as that will happen in the init function when registering the thermal zone device. I don't have any hardware to test the changes.

2020-11-26thermal: power allocator: change the 'k_i' coefficient estimationLukasz Luba
Intelligent Power Allocation (IPA) is built around the PID controller concept. The initialization code tries to setup the environment based on the information available in DT or estimate the value based on minimum power reported by each of the cooling device. The estimation will have an impact on the PID controller behaviour via the related 'k_po', 'k_pu', 'k_i' coefficients and also on the power budget calculation. This change prevents the situation when 'k_i' is relatively big compared to 'k_po' and 'k_pu' values. This might happen when the estimation for 'sustainable_power' returned small value, thus 'k_po' and 'k_pu' are small.

2020-11-07thermal: intel: pch: fix S0ix failure due to PCH temperature above thresholdSumeet Pawnikar
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.

2020-10-25kernel/sys.c: fix prototype of prctl_get_tid_address()Rasmus Villemoes
tid_addr is not a "pointer to (pointer to int in userspace)"; it is in fact a "pointer to (pointer to int in userspace) in userspace". So sparse rightfully complains about passing a kernel pointer to put_user().

2020-10-25mm: remove kzfree() compatibility definitionEric Biggers
Commit 453431a54934 ("mm, treewide: rename kzfree() to kfree_sensitive()") renamed kzfree() to kfree_sensitive(), but it left a compatibility definition of kzfree() to avoid being too disruptive. Since then a few more instances of kzfree() have slipped in. Just get rid of them and remove the compatibility definition once and for all.

This is the cleanup of the latest series of prandom_u32 experimentations consisting in using SipHash instead of Tausworthe to produce the randoms used by the network stack. The changes to the files were kept minimal, and the controversial commit that used to take noise from the fast_pool (f227e3ec3b5c) was reverted. Instead, a dedicated "net_rand_noise" per_cpu variable is fed from various sources of activities (networking, scheduling) to perturb the SipHash state using fast, non-trivially predictable data, instead of keeping it fully deterministic. The goal is essentially to make any occasional memory leakage or brute-force attempt useless. The resulting code was verified to be very slightly faster on x86_64 than what is was with the controversial commit above, though this remains barely above measurement noise. It was also tested on i386 and arm, and build- tested only on arm64" Link: https://lore.kernel.org/netdev/20200808152628.GA27941@SDF.ORG/ * tag '20201024-v4-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/prandom: random32: add a selftest for the prandom32 code random32: add noise from network and scheduling activity random32: make prandom_u32() output unpredictable
