2024-05-01hwmon: (max31790) revise the scale to write pwmDelphine CC Chiu1-1/+7
Since the value for PWMOUT Target Duty Cycle register is a 9 bit left-justified value that ranges from 0 to 511 and is contained in 2 bytes. There is an issue that the PWM signal recorded by oscilloscope would not be on consistently if we set PWM to 100% to the driver. It is because the LSB of the 9 bit would always be zero if it just left shift 8 bit for the value that write to PWMOUT Target Duty Cycle register. Therefore, revise the scale of the value that was written to pwm input from 255 to 511 and modify the value to left-justified value.

2024-04-30hwmon: (it87) Test for chipset before entering configuration modeFrank Crawford1-5/+47
Major part of the change for the new method to avoid chipset issues. The actual update does the following: 1) Lock the memory, but does not perform a SIO entry (previously it would have performed an SIO entry). 2) Attempt to read the chipID. This should be safe no matter which chip we have. 3) If step (2) fails, then perform SIO entry and retry chipID read. For older chips and on failure it acts similarly to prior to this patch. 4) Set the sio_data->type, similar to previously. 5) If we have not performed an SIO entry, and this is not a chip type with the NOCONF feature, then it will perform an SIO entry at this point. 6) Proceed with setup as prior to this patch. 7) Any following access to the SIO registers will invoke the SIO entry and SIO exit steps unless it is a chip with the NOCONF feature set. This was set up in the previous patches in this patchset. 8) Update to the exit based on if it had performed a SIO entry or not.

2024-04-28hwmon: (coretemp) Extend the bitmask to read temperature to 0xffRicardo Neri1-1/+1
The Intel Software Development manual defines the temperature digital readout as the bits [22:16] of the IA32_[PACKAGE]_THERM_STATUS registers. Bit 23 is specified as reserved. In recent processors, however, the temperature digital readout uses bits [23:16]. In those processors, using the bitmask 0x7f would lead to incorrect readings if the temperature deviates from TjMax by more than 127 degrees Celsius. Although not guaranteed, bit 23 is likely to be 0 in processors from a few generations ago. The temperature reading would still be correct in those processors when using a 0xff bitmask. Model-specific provisions can be made for older processors in which bit 23 is not 0 should the need arise.

2024-04-28hwmon: (aspeed-g6-pwm-tach) Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2024-03-12platform/x86: wmi: Do not instantiate older WMI drivers multiple timesArmin Wolf1-0/+1
Many older WMI drivers cannot be instantiated multiple times for two reasons: - they are using the legacy GUID-based WMI API - they are singletons (with global state) Prevent such WMI drivers from binding to WMI devices with a duplicated GUID, as this would mean that the WMI driver will be instantiated at least two times (one for the original GUID and one for the duplicated GUID). WMI drivers which can be instantiated multiple times can signal this by setting a flag inside struct wmi_driver. Tested on a ASUS Prime B650-Plus.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 APIC updates from Thomas Gleixner: "Rework of APIC enumeration and topology evaluation. The current implementation has a couple of shortcomings: - It fails to handle hybrid systems correctly. - The APIC registration code which handles CPU number assignents is in the middle of the APIC code and detached from the topology evaluation. - The various mechanisms which enumerate APICs, ACPI, MPPARSE and guest specific ones, tweak global variables as they see fit or in case of XENPV just hack around the generic mechanisms completely. - The CPUID topology evaluation code is sprinkled all over the vendor code and reevaluates global variables on every hotplug operation. - There is no way to analyze topology on the boot CPU before bringing up the APs. This causes problems for infrastructure like PERF which needs to size certain aspects upfront or could be simplified if that would be possible. - The APIC admission and CPU number association logic is incomprehensible and overly complex and needs to be kept around after boot instead of completing this right after the APIC enumeration. This update addresses these shortcomings with the following changes: - Rework the CPUID evaluation code so it is common for all vendors and provides information about the APIC ID segments in a uniform way independent of the number of segments (Thread, Core, Module, ..., Die, Package) so that this information can be computed instead of rewriting global variables of dubious value over and over. - A few cleanups and simplifcations of the APIC, IO/APIC and related interfaces to prepare for the topology evaluation changes. - Seperation of the parser stages so the early evaluation which tries to find the APIC address can be seperately overridden from the late evaluation which enumerates and registers the local APIC as further preparation for sanitizing the topology evaluation. - A new registration and admission logic which - encapsulates the inner workings so that parsers and guest logic cannot longer fiddle in it - uses the APIC ID segments to build topology bitmaps at registration time - provides a sane admission logic - allows to detect the crash kernel case, where CPU0 does not run on the real BSP, automatically. This is required to prevent sending INIT/SIPI sequences to the real BSP which would reset the whole machine. This was so far handled by a tedious command line parameter, which does not even work in nested crash scenarios. - Associates CPU number after the enumeration completed and prevents the late registration of APICs, which was somehow tolerated before. - Converting all parsers and guest enumeration mechanisms over to the new interfaces. This allows to get rid of all global variable tweaking from the parsers and enumeration mechanisms and sanitizes the XEN[PV] handling so it can use CPUID evaluation for the first time. - Mopping up existing sins by taking the information from the APIC ID segment bitmaps. This evaluates hybrid systems correctly on the boot CPU and allows for cleanups and fixes in the related drivers, e.g. PERF. The series has been extensively tested and the minimal late fallout due to a broken ACPI/MADT table has been addressed by tightening the admission logic further" * tag 'x86-apic-2024-03-10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (76 commits) x86/topology: Ignore non-present APIC IDs in a present package x86/apic: Build the x86 topology enumeration functions on UP APIC builds too smp: Provide 'setup_max_cpus' definition on UP too smp: Avoid 'setup_max_cpus' namespace collision/shadowing x86/bugs: Use fixed addressing for VERW operand x86/cpu/topology: Get rid of cpuinfo::x86_max_cores x86/cpu/topology: Provide __num_[cores|threads]_per_package x86/cpu/topology: Rename topology_max_die_per_package() x86/cpu/topology: Rename smp_num_siblings x86/cpu/topology: Retrieve cores per package from topology bitmaps x86/cpu/topology: Use topology logical mapping mechanism x86/cpu/topology: Provide logical pkg/die mapping x86/cpu/topology: Simplify cpu_mark_primary_thread() x86/cpu/topology: Mop up primary thread mask handling x86/cpu/topology: Use topology bitmaps for sizing x86/cpu/topology: Let XEN/PV use topology from CPUID/MADT x86/xen/smp_pv: Count number of vCPUs early x86/cpu/topology: Assign hotpluggable CPUIDs during init x86/cpu/topology: Reject unknown APIC IDs on ACPI hotplug x86/topology: Add a mechanism to track topology via APIC IDs ...

The driver support two functions: PWM and Tachometer. The PWM feature can handle up to 16 output ports, while the Tachometer can monitor to up to 16 input ports as well. This driver implements them by exposing two kernel subsystems: PWM and HWMON. The PWM subsystem can be utilized alongside existing drivers for controlling elements such as fans (pwm-fan.c), beepers (pwm-beeper.c) and so on. Through the HWMON subsystem, the driver provides sysfs interfaces for fan.

2024-02-25hwmon: (chipcap2) fix return path in cc2_request_alarm_irqs()Javier Carrasco1-5/+9
The return path can be improved by returning upon first failure. The current implementation would try to register the second interrupt even if the first one failed, which is unnecessary. Moreover, if no irqs are available, the return value should be zero (the driver supports the use case with no interrupts). Currently the initial value is unassigned and that may lead to returning an unknown value if stack variables are not automatically set to zero and no irqs were provided.

The reg_val variable in cc2_get_reg_val() might be used without a known value if cc2_read_reg() fails. That leads to a useless data conversion because the returned error means the read operation failed and the data is not relevant.
