2021-02-15thermal: qcom: add support for adc-tm5 PMIC thermal monitorDmitry Baryshkov
Add support for Thermal Monitoring part of PMIC5. This part is closely coupled with ADC, using it's channels directly. ADC-TM support generating interrupts on ADC value crossing low or high voltage bounds, which is used to support thermal trip points.

2021-02-15thermal: ti-soc-thermal: Simplify polling with iopollTony Lindgren
We can use iopoll for checking the EOCZ (end of conversion) bit. And with this we now also want to handle the timeout errors properly. For omap3, we need about 1.2ms for the single mode sampling to wait for EOCZ down, so let's use 1.5ms timeout there. Waiting for sampling to start is faster and we can use 1ms timeout.

2021-02-15thermal: ti-soc-thermal: Fix stuck sensor with continuous mode for 4430Tony Lindgren
At least for 4430, trying to use the single conversion mode eventually hangs the thermal sensor. This can be quite easily seen with errors: thermal thermal_zone0: failed to read out thermal zone (-5) Also, trying to read the temperature shows a stuck value with: $ while true; do cat /sys/class/thermal/thermal_zone0/temp; done Where the temperature is not rising at all with the busy loop. Additionally, the EOCZ (end of conversion) bit is not rising on 4430 in single conversion mode while it works fine in continuous conversion mode. It is also possible that the hung temperature sensor can affect the thermal shutdown alert too. Let's fix the issue by adding TI_BANDGAP_FEATURE_CONT_MODE_ONLY flag and use it for 4430. Note that we also need to add udelay to for the EOCZ (end of conversion) bit polling as otherwise we have it time out too early on 4430. We'll be changing the loop to use iopoll in the following clean-up patch.

2021-02-15thermal: ti-soc-thermal: Skip pointless register access for dra7Tony Lindgren
On dra7, there is no Start of Conversion (SOC) register bit and we have an empty bgap_soc_mask in the configuration for the thermal driver. Let's not do pointless reads and writes with the empty mask. There's also no point waiting for End of Conversion bit (EOCZ) to go high on dra7. We only care about it going down, and are now mostly timing out waiting for EOCZ high while it has already gone down. When we add checking for the timeout errors in a later patch, waiting for EOCZ high would cause bogus time out errors.

2021-01-19thermal: int340x: Fix unexpected shutdown at critical temperatureKai-Heng Feng
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.

2021-01-19thermal/core: Remove the 'forced_passive' optionDaniel Lezcano
The code was reorganized in 2012 with the commit 0c01ebbfd3caf1. The main change is a loop on the trip points array and a unconditional call to the throttle() ops of the governors for each of them even if the trip temperature is not reached yet. With this change, the 'forced_passive' is no longer checked in the thermal_zone_device_update() function but in the step wise governor's throttle() callback. As the force_passive does no belong to the trip point array, the thermal_zone_device_update() can not compare with the specified passive temperature, thus does not detect the passive limit has been crossed. Consequently, throttle() is never called and the 'forced_passive' branch is unreached. In addition, the default processor cooling device is not automatically bound to the thermal zone if there is not passive trip point, thus the 'forced_passive' can not operate. If there is an active trip point, then the throttle function will be called to mitigate at this temperature and the 'forced_passive' will override the mitigation of the active trip point in this case but with the default cooling device bound to the thermal zone, so usually a fan, and that is not a passive cooling effect. Given the regression exists since more than 8 years, nobody complained and at the best of my knowledge there is no bug open in https://bugzilla.kernel.org, it is reasonable to say it is unused. Remove the 'forced_passive' related code.

The big core two fixes are for power management ("block: Do not accept any requests while suspended" and "block: Fix a race in the runtime power management code") which finally sorts out the resume problems we've occasionally been having. To make the resume fix, there are seven necessary precursors which effectively renames REQ_PREEMPT to REQ_PM, so every "special" request in block is automatically a power management exempt one.

2021-01-01depmod: handle the case of /sbin/depmod without /sbin in PATHLinus Torvalds
Commit 436e980e2ed5 ("kbuild: don't hardcode depmod path") stopped hard-coding the path of depmod, but in the process caused trouble for distributions that had that /sbin location, but didn't have it in the PATH (generally because /sbin is limited to the super-user path). Work around it for now by just adding /sbin to the end of PATH in the depmod.sh script.

2020-12-30kernel/io_uring: cancel io_uring before task worksPavel Begunkov
For cancelling io_uring requests it needs either to be able to run currently enqueued task_works or having it shut down by that moment. Otherwise io_uring_cancel_files() may be waiting for requests that won't ever complete. Go with the first way and do cancellations before setting PF_EXITING and so before putting the task_work infrastructure into a transition state where task_work_run() would better not be called.

io_sqe_files_unregister() uninterruptibly waits for enqueued ref nodes, however requests keeping them may never complete, e.g. because of some userspace dependency.

2020-12-30intel_idle: add SnowRidge C-state tableArtem Bityutskiy
Add C-state table for the SnowRidge SoC which is found on Intel Jacobsville platforms. The following has been changed. 1. C1E latency changed from 10us to 15us. It was measured using the open source "wult" tool (the "nic" method, 15us is the 99.99th percentile). 2. C1E power break even changed from 20us to 25us, which may result in less C1E residency in some workloads. 3. C6 latency changed from 50us to 130us. Measured the same way as C1E. The C6 C-state is supported only by some SnowRidge revisions, so add a C-state table commentary about this. On SnowRidge, C6 support is enumerated via the usual mechanism: "mwait" leaf of the "cpuid" instruction. The 'intel_idle' driver does check this leaf, so even though C6 is present in the table, the driver will only use it if the CPU does support it.

2020-12-30cpufreq: intel_pstate: Fix fast-switch fallback pathRafael J. Wysocki
When sugov_update_single_perf() falls back to the "frequency" path due to the missing scale-invariance, it will call cpufreq_driver_fast_switch() via sugov_fast_switch() and the driver's ->fast_switch() callback will be invoked, so it must not be NULL. However, after commit a365ab6b9dfb ("cpufreq: intel_pstate: Implement the ->adjust_perf() callback") intel_pstate sets ->fast_switch() to NULL when it is going to use intel_cpufreq_adjust_perf(), which is a mistake, because on x86 the scale-invariance may be turned off dynamically, so modify it to retain the original ->adjust_perf() callback pointer.
