Zqiang	8780129cbc	smp: Add missing destroy_work_on_stack() call in smp_call_on_cpu() [ Upstream commit 77aeb1b685f9db73d276bad4bb30d48505a6fd23 ] For CONFIG_DEBUG_OBJECTS_WORK=y kernels sscs.work defined by INIT_WORK_ONSTACK() is initialized by debug_object_init_on_stack() for the debug check in __init_work() to work correctly. But this lacks the counterpart to remove the tracked object from debug objects again, which will cause a debug object warning once the stack is freed. Add the missing destroy_work_on_stack() invocation to cure that.

Nadav Amit	89496d80bf	smp: Fix offline cpu check in flush_smp_call_function_queue() commit 9e949a3886356fe9112c6f6f34a6e23d1d35407f upstream. The check in flush_smp_call_function_queue() for callbacks that are sent to offline CPUs currently checks whether the queue is empty. However, flush_smp_call_function_queue() has just deleted all the callbacks from the queue and moved all the entries into a local list. This checks would only be positive if some callbacks were added in the short time after llist_del_all() was called. This does not seem to be the intention of this check. Change the check to look at the local list to which the entries were moved instead of the queue from which all the callbacks were just removed.

Arnd Bergmann	41f1aed56d	smp: Fix smp_call_function_single_async prototype commit 1139aeb1c521eb4a050920ce6c64c36c4f2a3ab7 upstream. As of commit `966a967116` ("smp: Avoid using two cache lines for struct call_single_data"), the smp code prefers 32-byte aligned call_single_data objects for performance reasons, but the block layer includes an instance of this structure in the main 'struct request' that is more senstive to size than to performance here, see `4ccafe0320` ("block: unalign call_single_data in struct request"). The result is a violation of the calling conventions that clang correctly points out: block/blk-mq.c:630:39: warning: passing 8-byte aligned argument to 32-byte aligned parameter 2 of 'smp_call_function_single_async' may result in an unaligned pointer access [-Walign-mismatch] smp_call_function_single_async(cpu, &rq->csd); It does seem that the usage of the call_single_data without cache line alignment should still be allowed by the smp code, so just change the function prototype so it accepts both, but leave the default alignment unchanged for the other users. This seems better to me than adding a local hack to shut up an otherwise correct warning in the caller.

Sebastian Andrzej Siewior	7a9b76bb9b	smp: Process pending softirqs in flush_smp_call_function_from_idle() [ Upstream commit 66040b2d5d41f85cb1a752a75260595344c5ec3b ] send_call_function_single_ipi() may wake an idle CPU without sending an IPI. The woken up CPU will process the SMP-functions in flush_smp_call_function_from_idle(). Any raised softirq from within the SMP-function call will not be processed. Should the CPU have no tasks assigned, then it will go back to idle with pending softirqs and the NOHZ will rightfully complain. Process pending softirqs on return from flush_smp_call_function_queue().

Paul E. McKenney	35feb60474	kernel/smp: Provide CSD lock timeout diagnostics This commit causes csd_lock_wait() to emit diagnostics when a CPU fails to respond quickly enough to one of the smp_call_function() family of function calls.

Paul E. McKenney	e48c15b796	smp: Add source and destination CPUs to __call_single_data This commit adds a destination CPU to __call_single_data, and is inspired by an earlier commit by Peter Zijlstra. This version adds #ifdef to permit use by 32-bit systems and supplying the destination CPU for all smp_call_function*() requests, not just smp_call_function_single(). If need be, 32-bit systems could be accommodated by shrinking the flags field to 16 bits (the atomic_t variant is currently unused) and by providing only eight bits for CPU on such systems. It is not clear that the addition of the fields to __call_single_node are really needed.

Peter Zijlstra	a148866489	sched: Replace rq::wake_list The recent commit: `90b5363acd` ("sched: Clean up scheduler_ipi()") got smp_call_function_single_async() subtly wrong. Even though it will return -EBUSY when trying to re-use a csd, that condition is not atomic and still requires external serialization. The change in ttwu_queue_remote() got this wrong. While on first reading ttwu_queue_remote() has an atomic test-and-set that appears to serialize the use, the matching 'release' is not in the right place to actually guarantee this serialization. The actual race is vs the sched_ttwu_pending() call in the idle loop; that can run the wakeup-list without consuming the CSD. Instead of trying to chain the lists, merge them.

Peter Zijlstra	4b44a21dd6	irq_work, smp: Allow irq_work on call_single_queue Currently irq_work_queue_on() will issue an unconditional arch_send_call_function_single_ipi() and has the handler do irq_work_run(). This is unfortunate in that it makes the IPI handler look at a second cacheline and it misses the opportunity to avoid the IPI.

Peter Xu	5a18ceca63	smp: Allow smp_call_function_single_async() to insert locked csd Previously we will raise an warning if we want to insert a csd object which is with the LOCK flag set, and if it happens we'll also wait for the lock to be released. However, this operation does not match perfectly with how the function is named - the name with "_async" suffix hints that this function should not block, while we will. This patch changed this behavior by simply return -EBUSY instead of waiting, at the meantime we allow this operation to happen without warning the user to change this into a feature when the caller wants to "insert a csd object, if it's there, just wait for that one". This is pretty safe because in flush_smp_call_function_queue() for async csd objects (where csd->flags&SYNC is zero) we'll first do the unlock then we call the csd->func(). So if we see the csd->flags&LOCK is true in smp_call_function_single_async(), then it's guaranteed that csd->func() will be called after this smp_call_function_single_async() returns -EBUSY.

Josh Poimboeuf	b284909aba	cpu/hotplug: Fix "SMT disabled by BIOS" detection for KVM With the following commit: `73d5e2b472` ("cpu/hotplug: detect SMT disabled by BIOS") ... the hotplug code attempted to detect when SMT was disabled by BIOS, in which case it reported SMT as permanently disabled. However, that code broke a virt hotplug scenario, where the guest is booted with only primary CPU threads, and a sibling is brought online later. The problem is that there doesn't seem to be a way to reliably distinguish between the HW "SMT disabled by BIOS" case and the virt "sibling not yet brought online" case. So the above-mentioned commit was a bit misguided, as it permanently disabled SMT for both cases, preventing future virt sibling hotplugs. Going back and reviewing the original problems which were attempted to be solved by that commit, when SMT was disabled in BIOS: 1) /sys/devices/system/cpu/smt/control showed "on" instead of "notsupported"; and 2) vmx_vm_init() was incorrectly showing the L1TF_MSG_SMT warning. I'd propose that we instead consider #1 above to not actually be a problem. Because, at least in the virt case, it's possible that SMT wasn't disabled by BIOS and a sibling thread could be brought online later. So it makes sense to just always default the smt control to "on" to allow for that possibility (assuming cpuid indicates that the CPU supports SMT). The real problem is #2, which has a simple fix: change vmx_vm_init() to query the actual current SMT state -- i.e., whether any siblings are currently online -- instead of looking at the SMT "control" sysfs value. So fix it by: a) reverting the original "fix" and its followup fix: `73d5e2b472` ("cpu/hotplug: detect SMT disabled by BIOS") `bc2d8d262c` ("cpu/hotplug: Fix SMT supported evaluation") and b) changing vmx_vm_init() to query the actual current SMT state -- instead of the sysfs control value -- to determine whether the L1TF warning is needed. This also requires the 'sched_smt_present' variable to exported, instead of 'cpu_smt_control'.

Thomas Gleixner	bc2d8d262c	cpu/hotplug: Fix SMT supported evaluation Josh reported that the late SMT evaluation in cpu_smt_state_init() sets cpu_smt_control to CPU_SMT_NOT_SUPPORTED in case that 'nosmt' was supplied on the kernel command line as it cannot differentiate between SMT disabled by BIOS and SMT soft disable via 'nosmt'. That wreckages the state and makes the sysfs interface unusable. Rework this so that during bringup of the non boot CPUs the availability of SMT is determined in cpu_smt_allowed(). If a newly booted CPU is not a 'primary' thread then set the local cpu_smt_available marker and evaluate this explicitely right after the initial SMP bringup has finished. SMT evaulation on x86 is a trainwreck as the firmware has all the information _before_ booting the kernel, but there is no interface to query it.

Ying Huang	966a967116	smp: Avoid using two cache lines for struct call_single_data struct call_single_data is used in IPIs to transfer information between CPUs. Its size is bigger than sizeof(unsigned long) and less than cache line size. Currently it is not allocated with any explicit alignment requirements. This makes it possible for allocated call_single_data to cross two cache lines, which results in double the number of the cache lines that need to be transferred among CPUs. This can be fixed by requiring call_single_data to be aligned with the size of call_single_data. Currently the size of call_single_data is the power of 2. If we add new fields to call_single_data, we may need to add padding to make sure the size of new definition is the power of 2 as well. Fortunately, this is enforced by GCC, which will report bad sizes. To set alignment requirements of call_single_data to the size of call_single_data, a struct definition and a typedef is used. To test the effect of the patch, I used the vm-scalability multiple thread swap test case (swap-w-seq-mt). The test will create multiple threads and each thread will eat memory until all RAM and part of swap is used, so that huge number of IPIs are triggered when unmapping memory. In the test, the throughput of memory writing improves ~5% compared with misaligned call_single_data, because of faster IPIs.

Peter Zijlstra	6c8557bdb2	smp, cpumask: Use non-atomic cpumask_{set,clear}_cpu() The cpumasks in smp_call_function_many() are private and not subject to concurrency, atomic bitops are pointless and expensive.

Aaron Lu	3fc5b3b6a8	smp: Avoid sending needless IPI in smp_call_function_many() Inter-Processor-Interrupt(IPI) is needed when a page is unmapped and the process' mm_cpumask() shows the process has ever run on other CPUs. page migration, page reclaim all need IPIs. The number of IPI needed to send to different CPUs is especially large for multi-threaded workload since mm_cpumask() is per process. For smp_call_function_many(), whenever a CPU queues a CSD to a target CPU, it will send an IPI to let the target CPU to handle the work. This isn't necessary - we need only send IPI when queueing a CSD to an empty call_single_queue. The reason: flush_smp_call_function_queue() that is called upon a CPU receiving an IPI will empty the queue and then handle all of the CSDs there. So if the target CPU's call_single_queue is not empty, we know that: i. An IPI for the target CPU has already been sent by 'previous queuers'; ii. flush_smp_call_function_queue() hasn't emptied that CPU's queue yet. Thus, it's safe for us to just queue our CSD there without sending an addtional IPI. And for the 'previous queuers', we can limit it to the first queuer. To demonstrate the effect of this patch, a multi-thread workload that spawns 80 threads to equally consume 100G memory is used. This is tested on a 2 node broadwell-EP which has 44cores/88threads and 32G memory. So after 32G memory is used up, page reclaiming starts to happen a lot. With this patch, IPI number dropped 88% and throughput increased about 15% for the above workload.

Ingo Molnar	4c822698cb	sched/headers: Prepare for new header dependencies before moving code to <linux/sched/idle.h> We are going to split <linux/sched/idle.h> out of <linux/sched.h>, which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder <linux/sched/idle.h> file that just maps to <linux/sched.h> to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

Michael Ellerman	51111dce25	kernel/smp: Tell the user we're bringing up secondary CPUs Currently we don't print anything before starting to bring up secondary CPUs. This can be confusing if it takes a long time to bring up the secondaries, or if the kernel crashes while doing so and produces no further output. On x86 they work around this by detecting when the first secondary CPU comes up and printing a message (see announce_cpu()). But doing it in smp_init() is simpler and works for all arches.
