git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull performance event updates from Ingo Molnar: - Add CPU-PMU support for Intel Sapphire Rapids CPUs - Extend the perf ABI with PERF_SAMPLE_WEIGHT_STRUCT, to offer two-parameter sampling event feedback. Not used yet, but is intended for Golden Cove CPU-PMU, which can provide both the instruction latency and the cache latency information for memory profiling events. - Remove experimental, default-disabled perfmon-v4 counter_freezing support that could only be enabled via a boot option. The hardware is hopelessly broken, we'd like to make sure nobody starts relying on this, as it would only end in tears. - Fix energy/power events on Intel SPR platforms - Simplify the uprobes resume_execution() logic - Misc smaller fixes. * tag 'perf-core-2021-02-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: perf/x86/rapl: Fix psys-energy event on Intel SPR platform perf/x86/rapl: Only check lower 32bits for RAPL energy counters perf/x86/rapl: Add msr mask support perf/x86/kvm: Add Cascade Lake Xeon steppings to isolation_ucodes[] perf/x86/intel: Support CPUID 10.ECX to disable fixed counters perf/x86/intel: Add perf core PMU support for Sapphire Rapids perf/x86/intel: Filter unsupported Topdown metrics event perf/x86/intel: Factor out intel_update_topdown_event() perf/core: Add PERF_SAMPLE_WEIGHT_STRUCT perf/intel: Remove Perfmon-v4 counter_freezing support x86/perf: Use static_call for x86_pmu.guest_get_msrs perf/x86/intel/uncore: With > 8 nodes, get pci bus die id from NUMA info perf/x86/intel/uncore: Store the logical die id instead of the physical die id. x86/kprobes: Do not decode opcode in resume_execution()

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull scheduler updates from Ingo Molnar: "Core scheduler updates: - Add CONFIG_PREEMPT_DYNAMIC: this in its current form adds the preempt=none/voluntary/full boot options (default: full), to allow distros to build a PREEMPT kernel but fall back to close to PREEMPT_VOLUNTARY (or PREEMPT_NONE) runtime scheduling behavior via a boot time selection. There's also the /debug/sched_debug switch to do this runtime. This feature is implemented via runtime patching (a new variant of static calls). The scope of the runtime patching can be best reviewed by looking at the sched_dynamic_update() function in kernel/sched/core.c. ( Note that the dynamic none/voluntary mode isn't 100% identical, for example preempt-RCU is available in all cases, plus the preempt count is maintained in all models, which has runtime overhead even with the code patching. ) The PREEMPT_VOLUNTARY/PREEMPT_NONE models, used by the vast majority of distributions, are supposed to be unaffected. - Fix ignored rescheduling after rcu_eqs_enter(). This is a bug that was found via rcutorture triggering a hang. The bug is that rcu_idle_enter() may wake up a NOCB kthread, but this happens after the last generic need_resched() check. Some cpuidle drivers fix it by chance but many others don't. In true 2020 fashion the original bug fix has grown into a 5-patch scheduler/RCU fix series plus another 16 RCU patches to address the underlying issue of missed preemption events. These are the initial fixes that should fix current incarnations of the bug. - Clean up rbtree usage in the scheduler, by providing & using the following consistent set of rbtree APIs: partial-order; less() based: - rb_add(): add a new entry to the rbtree - rb_add_cached(): like rb_add(), but for a rb_root_cached total-order; cmp() based: - rb_find(): find an entry in an rbtree - rb_find_add(): find an entry, and add if not found - rb_find_first(): find the first (leftmost) matching entry - rb_next_match(): continue from rb_find_first() - rb_for_each(): iterate a sub-tree using the previous two - Improve the SMP/NUMA load-balancer: scan for an idle sibling in a single pass. This is a 4-commit series where each commit improves one aspect of the idle sibling scan logic. - Improve the cpufreq cooling driver by getting the effective CPU utilization metrics from the scheduler - Improve the fair scheduler's active load-balancing logic by reducing the number of active LB attempts & lengthen the load-balancing interval. This improves stress-ng mmapfork performance. - Fix CFS's estimated utilization (util_est) calculation bug that can result in too high utilization values Misc updates & fixes: - Fix the HRTICK reprogramming & optimization feature - Fix SCHED_SOFTIRQ raising race & warning in the CPU offlining code - Reduce dl_add_task_root_domain() overhead - Fix uprobes refcount bug - Process pending softirqs in flush_smp_call_function_from_idle() - Clean up task priority related defines, remove *USER_*PRIO and USER_PRIO() - Simplify the sched_init_numa() deduplication sort - Documentation updates - Fix EAS bug in update_misfit_status(), which degraded the quality of energy-balancing - Smaller cleanups" * tag 'sched-core-2021-02-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (51 commits) sched,x86: Allow !PREEMPT_DYNAMIC entry/kvm: Explicitly flush pending rcuog wakeup before last rescheduling point entry: Explicitly flush pending rcuog wakeup before last rescheduling point rcu/nocb: Trigger self-IPI on late deferred wake up before user resume rcu/nocb: Perform deferred wake up before last idle's need_resched() check rcu: Pull deferred rcuog wake up to rcu_eqs_enter() callers sched/features: Distinguish between NORMAL and DEADLINE hrtick sched/features: Fix hrtick reprogramming sched/deadline: Reduce rq lock contention in dl_add_task_root_domain() uprobes: (Re)add missing get_uprobe() in __find_uprobe() smp: Process pending softirqs in flush_smp_call_function_from_idle() sched: Harden PREEMPT_DYNAMIC static_call: Allow module use without exposing static_call_key sched: Add /debug/sched_preempt preempt/dynamic: Support dynamic preempt with preempt= boot option preempt/dynamic: Provide irqentry_exit_cond_resched() static call preempt/dynamic: Provide preempt_schedule[_notrace]() static calls preempt/dynamic: Provide cond_resched() and might_resched() static calls preempt: Introduce CONFIG_PREEMPT_DYNAMIC static_call: Provide DEFINE_STATIC_CALL_RET0() ...

2021-02-17static_call: Allow module use without exposing static_call_keyJosh Poimboeuf1-0/+7
When exporting static_call_key; with EXPORT_STATIC_CALL*(), the module can use static_call_update() to change the function called. This is not desirable in general. Not exporting static_call_key however also disallows usage of static_call(), since objtool needs the key to construct the static_call_site. Solve this by allowing objtool to create the static_call_site using the trampoline address when it builds a module and cannot find the static_call_key symbol. The module loader will then try and map the trampole back to a key before it constructs the normal sites list. Doing this requires a trampoline -> key associsation, so add another magic section that keeps those.

Introduce a dedicated option to tune preemption flavour at boot time, This will be only available on architectures efficiently supporting static calls in order not to tempt with the feature against additional overhead that might be prohibitive or undesirable. CONFIG_PREEMPT_DYNAMIC is automatically selected by CONFIG_PREEMPT if the architecture provides the necessary support (CONFIG_STATIC_CALL_INLINE, CONFIG_GENERIC_ENTRY, and provide with __preempt_schedule_function() / __preempt_schedule_notrace_function()).

The function can be cast to any function pointer type that has a single %RAX return (including pointers). Also provide a version that returns an int for convenience. We are clearing the entire %RAX register in any case, whether the return value is 32 or 64 bits, since %RAX is always a scratch register anyway.

The only remaining use of MAX_USER_PRIO (and USER_PRIO) is the SCALE_PRIO() definition in the PowerPC Cell architecture's Synergistic Processor Unit (SPU) scheduler. TASK_USER_PRIO isn't used anymore. Commit fe443ef2ac42 ("[POWERPC] spusched: Dynamic timeslicing for SCHED_OTHER") copied SCALE_PRIO() from the task scheduler in v2.6.23. Commit a4ec24b48dde ("sched: tidy up SCHED_RR") removed it from the task scheduler in v2.6.24. Commit 3ee237dddcd8 ("sched/prio: Add 3 macros of MAX_NICE, MIN_NICE and NICE_WIDTH in prio.h") introduced NICE_WIDTH much later. With: MAX_USER_PRIO = USER_PRIO(MAX_PRIO) = MAX_PRIO - MAX_RT_PRIO MAX_PRIO = MAX_RT_PRIO + NICE_WIDTH MAX_USER_PRIO = MAX_RT_PRIO + NICE_WIDTH - MAX_RT_PRIO MAX_USER_PRIO = NICE_WIDTH MAX_USER_PRIO can be replaced by NICE_WIDTH to be able to remove all the {*_}USER_PRIO defines.

So here's more fixes... Thanks Murphy. Anyway, three more x86/urgent fixes for 5.11 final. We should be finally ready (famous last words). :-) - An SGX use after free fix - A fix for the fix to disable CET instrumentation generation for kernel code.
