2021-07-04thermal/drivers/int340x/processor_thermal: Add PCI MMIO based thermal driverSrinivas Pandruvada4-1/+373
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.

2021-07-04thermal/drivers/int340x/processor_thermal: Split enumeration and processing partSrinivas Pandruvada5-259/+286
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.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull scheduler udpates from Ingo Molnar: - Changes to core scheduling facilities: - Add "Core Scheduling" via CONFIG_SCHED_CORE=y, which enables coordinated scheduling across SMT siblings. This is a much requested feature for cloud computing platforms, to allow the flexible utilization of SMT siblings, without exposing untrusted domains to information leaks & side channels, plus to ensure more deterministic computing performance on SMT systems used by heterogenous workloads. There are new prctls to set core scheduling groups, which allows more flexible management of workloads that can share siblings. - Fix task->state access anti-patterns that may result in missed wakeups and rename it to ->__state in the process to catch new abuses. - Load-balancing changes: - Tweak newidle_balance for fair-sched, to improve 'memcache'-like workloads. - "Age" (decay) average idle time, to better track & improve workloads such as 'tbench'. - Fix & improve energy-aware (EAS) balancing logic & metrics. - Fix & improve the uclamp metrics. - Fix task migration (taskset) corner case on !CONFIG_CPUSET. - Fix RT and deadline utilization tracking across policy changes - Introduce a "burstable" CFS controller via cgroups, which allows bursty CPU-bound workloads to borrow a bit against their future quota to improve overall latencies & batching. Can be tweaked via /sys/fs/cgroup/cpu/<X>/cpu.cfs_burst_us. - Rework assymetric topology/capacity detection & handling. - Scheduler statistics & tooling: - Disable delayacct by default, but add a sysctl to enable it at runtime if tooling needs it. Use static keys and other optimizations to make it more palatable. - Use sched_clock() in delayacct, instead of ktime_get_ns(). - Misc cleanups and fixes. * tag 'sched-core-2021-06-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (72 commits) sched/doc: Update the CPU capacity asymmetry bits sched/topology: Rework CPU capacity asymmetry detection sched/core: Introduce SD_ASYM_CPUCAPACITY_FULL sched_domain flag psi: Fix race between psi_trigger_create/destroy sched/fair: Introduce the burstable CFS controller sched/uclamp: Fix uclamp_tg_restrict() sched/rt: Fix Deadline utilization tracking during policy change sched/rt: Fix RT utilization tracking during policy change sched: Change task_struct::state sched,arch: Remove unused TASK_STATE offsets sched,timer: Use __set_current_state() sched: Add get_current_state() sched,perf,kvm: Fix preemption condition sched: Introduce task_is_running() sched: Unbreak wakeups sched/fair: Age the average idle time sched/cpufreq: Consider reduced CPU capacity in energy calculation sched/fair: Take thermal pressure into account while estimating energy thermal/cpufreq_cooling: Update offline CPUs per-cpu thermal_pressure sched/fair: Return early from update_tg_cfs_load() if delta == 0 ...

2021-06-17thermal/cpufreq_cooling: Update offline CPUs per-cpu thermal_pressureLukasz Luba1-1/+1
The thermal pressure signal gives information to the scheduler about reduced CPU capacity due to thermal. It is based on a value stored in a per-cpu 'thermal_pressure' variable. The online CPUs will get the new value there, while the offline won't. Unfortunately, when the CPU is back online, the value read from per-cpu variable might be wrong (stale data). This might affect the scheduler decisions, since it sees the CPU capacity differently than what is actually available. Fix it by making sure that all online+offline CPUs would get the proper value in their per-cpu variable when thermal framework sets capping.

This one limits the fallout until proper enablement. - Use cpu_feature_enabled() in the idxd driver so that it can be build-time disabled through the defines in disabled-features.h. - Fix LVT thermal setup for SMI delivery mode by making sure the APIC LVT value is read before APIC initialization so that softlockups during boot do not happen at least on one machine. - Mark all legacy interrupts as legacy vectors when the IO-APIC is disabled and when all legacy interrupts are routed through the PIC" * tag 'x86_urgent_for_v5.13-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/sev: Check SME/SEV support in CPUID first x86/fault: Don't send SIGSEGV twice on SEGV_PKUERR x86/setup: Always reserve the first 1M of RAM x86/alternative: Optimize single-byte NOPs at an arbitrary position x86/cpufeatures: Force disable X86_FEATURE_ENQCMD and remove update_pasid() dmaengine: idxd: Use cpu_feature_enabled() x86/thermal: Fix LVT thermal setup for SMI delivery mode x86/apic: Mark _all_ legacy interrupts when IO/APIC is missing
2021-05-31x86/thermal: Fix LVT thermal setup for SMI delivery modeBorislav Petkov1-4/+11
There are machines out there with added value crap^WBIOS which provide an SMI handler for the local APIC thermal sensor interrupt. Out of reset, the BSP on those machines has something like 0x200 in that APIC register (timestamps left in because this whole issue is timing sensitive): [ 0.033858] read lvtthmr: 0x330, val: 0x200 which means: - bit 16 - the interrupt mask bit is clear and thus that interrupt is enabled - bits [10:8] have 010b which means SMI delivery mode. Now, later during boot, when the kernel programs the local APIC, it soft-disables it temporarily through the spurious vector register: setup_local_APIC: ... /* * If this comes from kexec/kcrash the APIC might be enabled in * SPIV. Soft disable it before doing further initialization. */ value = apic_read(APIC_SPIV); value &= ~APIC_SPIV_APIC_ENABLED; apic_write(APIC_SPIV, value); which means (from the SDM): "10.4.7.2 Local APIC State After It Has Been Software Disabled ... * The mask bits for all the LVT entries are set. Attempts to reset these bits will be ignored." And this happens too: [ 0.124111] APIC: Switch to symmetric I/O mode setup [ 0.124117] lvtthmr 0x200 before write 0xf to APIC 0xf0 [ 0.124118] lvtthmr 0x10200 after write 0xf to APIC 0xf0 This results in CPU 0 soft lockups depending on the placement in time when the APIC soft-disable happens. Those soft lockups are not 100% reproducible and the reason for that can only be speculated as no one tells you what SMM does. Likely, it confuses the SMM code that the APIC is disabled and the thermal interrupt doesn't doesn't fire at all, leading to CPU 0 stuck in SMM forever... Now, before 4f432e8bb15b ("x86/mce: Get rid of mcheck_intel_therm_init()") due to how the APIC_LVTTHMR was read before APIC initialization in mcheck_intel_therm_init(), it would read the value with the mask bit 16 clear and then intel_init_thermal() would replicate it onto the APs and all would be peachy - the thermal interrupt would remain enabled. But that commit moved that reading to a later moment in intel_init_thermal(), resulting in reading APIC_LVTTHMR on the BSP too late and with its interrupt mask bit set. Thus, revert back to the old behavior of reading the thermal LVT register before the APIC gets initialized.

2021-05-14thermal/drivers/intel: Initialize RW trip to THERMAL_TEMP_INVALIDSrinivas Pandruvada2-1/+5
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.
