2020-12-11rtc: core: Make the sync offset default more realisticThomas Gleixner
The offset which is used to steer the start of an RTC synchronization update via rtc_set_ntp_time() is huge. The math behind this is: tsched twrite(t2.tv_sec - 1) t2 (seconds increment) twrite - tsched is the transport time for the write to hit the device. t2 - twrite depends on the chip and is for most chips one second. The rtc_set_ntp_time() calculation of tsched is: tsched = t2 - 1sec - (t2 - twrite) The default for the sync offset is 500ms which means that twrite - tsched is 500ms assumed that t2 - twrite is one second. This is 0.5 seconds off for RTCs which are directly accessible by IO writes and probably for the majority of i2C/SPI based RTC off by an order of magnitude. Set it to 5ms which should bring it closer to reality. The default can be adjusted by drivers (rtc_cmos does so) and could be adjusted further by a calibration method which is an orthogonal problem.

2020-12-11rtc: cmos: Make rtc_cmos sync offset correctThomas Gleixner
The offset for rtc_cmos must be -500ms to work correctly with the current implementation of rtc_set_ntp_time() due to the following: tsched twrite(t2.tv_sec - 1) t2 (seconds increment) twrite - tsched is the transport time for the write to hit the device, which is negligible for this chip because it's accessed directly. t2 - twrite = 500ms according to the datasheet. But rtc_set_ntp_time() calculation of tsched is: tsched = t2 - 1sec - (t2 - twrite) The default for the sync offset is 500ms which means that the write happens at t2 - 1.5 seconds which is obviously off by a second for this device. Make the offset -500ms so it works correct.

2020-12-11rtc: mc146818: Prevent reading garbageThomas Gleixner
The MC146818 driver is prone to read garbage from the RTC. There are several issues all related to the update cycle of the MC146818. The chip increments seconds obviously once per second and indicates that by a bit in a register. The bit goes high 244us before the actual update starts. During the update the readout of the time values is undefined. The code just checks whether the update in progress bit (UIP) is set before reading the clock. If it's set it waits arbitrary 20ms before retrying, which is ample because the maximum update time is ~2ms. But this check does not guarantee that the UIP bit goes high and the actual update happens during the readout. So the following can happen 0.997 UIP = False -> Interrupt/NMI/preemption 0.998 UIP -> True 0.999 Readout <- Undefined To prevent this rework the code so it checks UIP before and after the readout and if set after the readout try again. But that's not enough to cover the following: 0.997 UIP = False Readout seconds -> NMI (or vCPU scheduled out) 0.998 UIP -> True update completes UIP -> False 1.000 Readout minutes,.... UIP check succeeds That can make the readout wrong up to 59 seconds. To prevent this, read the seconds value before the first UIP check, validate it after checking UIP and after reading out the rest. It's amazing that the original i386 code had this actually correct and the generic implementation of the MC146818 driver got it wrong in 2002 and it stayed that way until today.

2020-12-11sched/fair: Clear SMT siblings after determining the core is not idleMel Gorman
The clearing of SMT siblings from the SIS mask before checking for an idle core is a small but unnecessary cost. Defer the clearing of the siblings until the scan moves to the next potential target. The cost of this was not measured as it is borderline noise but it should be self-evident.

The value freq_max/freq_base is a fundamental component of frequency invariance calculations. It may come from a variety of sources such as MSRs or ACPI data, tracking it down when troubleshooting a system could be non-trivial.

2020-12-11x86, sched: Use midpoint of max_boost and max_P for frequency invariance on ↵Giovanni Gherdovich
AMD EPYC Frequency invariant accounting calculations need the ratio freq_curr/freq_max, but freq_max is unknown as it depends on dynamic power allocation between cores: AMD EPYC CPUs implement "Core Performance Boost". Three candidates are considered to estimate this value: - maximum non-boost frequency - maximum boost frequency - the mid point between the above two Experimental data on an AMD EPYC Zen2 machine slightly favors the third option, which is applied with this patch. The analysis uses the ondemand cpufreq governor as baseline, and compares it with schedutil in a number of configurations. Using the freq_max value described above offers a moderate advantage in performance and efficiency: sugov-max (freq_max=max_boost) performs the worst on tbench: less throughput and reduced efficiency than the other invariant-schedutil options (see "Data Overview" below). Consider that tbench is generally a problematic case as no schedutil version currently is better than ondemand. sugov-P0 (freq_max=max_P) is the worst on dbench, while the other sugov's can surpass ondemand with less filesystem latency and slightly increased efficiency. 1.

2020-12-11x86, sched: Calculate frequency invariance for AMD systemsNathan Fontenot
This is the first pass in creating the ability to calculate the frequency invariance on AMD systems. This approach uses the CPPC highest performance and nominal performance values that range from 0 - 255 instead of a high and base frquency. This is because we do not have the ability on AMD to get a highest frequency value. On AMD systems the highest performance and nominal performance vaues do correspond to the highest and base frequencies for the system so using them should produce an appropriate ratio but some tweaking is likely necessary. Due to CPPC being initialized later in boot than when the frequency invariant calculation is currently made, I had to create a callback from the CPPC init code to do the calculation after we have CPPC data. Special thanks to "kernel test robot <lkp@intel.com>" for reporting that compilation of drivers/acpi/cppc_acpi.c is conditional to CONFIG_ACPI_CPPC_LIB, not just CONFIG_ACPI.

The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure that both `delay_usecs` & `delay` are used (in this order to preserve backwards compatibility).

2020-12-10selftests/bpf: Silence ima_setup.sh when not running in verbose mode.KP Singh
Currently, ima_setup.sh spews outputs from commands like mkfs and dd on the terminal without taking into account the verbosity level of the test framework. Update test_progs to set the environment variable SELFTESTS_VERBOSE=1 when a verbose output is requested. This environment variable is then used by ima_setup.sh (and can be used by other similar scripts) to obey the verbosity level of the test harness without needing to re-implement command line options for verbosity. In "silent" mode, the script saves the output to a temporary file, the contents of which are echoed back to stderr when the script encounters an error.

2020-12-10Input: edt-ft5x06 - consolidate handling of number of electrodesDmitry Torokhov
Instead of special-casing retrieval of number of X/Y electrodes based on the firmware, let's select default values and mark registers as non-existent on firmwares that do not support this operation. Also mark "report rate" register as non-existent for generic firmwares as having it set to 0 does not make sense.

2020-12-10selftests/bpf: Drop the need for LLVM's llcAndrew Delgadillo
LLC is meant for compiler development and debugging. Consequently, it exposes many low level options about its backend. To avoid future bugs introduced by using the raw LLC tool, use clang directly so that all appropriate options are passed to the back end. Additionally, simplify the Makefile by removing the CLANG_NATIVE_BPF_BUILD_RULE as it is not being use, stop passing dwarfris attr since elfutils/libdw now supports the bpf backend (which should work with any recent pahole), and stop passing alu32 since -mcpu=v3 implies alu32.

2020-12-10selftests/bpf: fix bpf_testmod.ko recompilation logicAndrii Nakryiko
bpf_testmod.ko build rule declared dependency on VMLINUX_BTF, but the variable itself was initialized after the rule was declared, which often caused bpf_testmod.ko to not be re-compiled. Fix by moving VMLINUX_BTF determination sooner. Also enforce bpf_testmod.ko recompilation when we detect that vmlinux image changed by removing bpf_testmod/bpf_testmod.ko. This is necessary to generate correct module's split BTF. Without it, Kbuild's module build logic might determine that nothing changed on the kernel side and thus bpf_testmod.ko shouldn't be rebuilt, so won't re-generate module BTF, which often leads to module's BTF with wrong string offsets against vmlinux BTF. Removing .ko file forces Kbuild to re-build the module.
