The 'trace' tool was accepting any names passed and just looking if syscalls returned via the raw_syscalls:* tracepoints were in that list, leading to it accepting perf events and then never finding any, as those are not valid syscall names, confusing users. Fix it by checking each entry in the list using audit_name_to_syscall, telling the user which entries are invalid and suggesting where to look for valid syscall names. E.g: [root@zoo ~]# trace -e open,foo,bar,close,baz Error: Invalid syscall bar, baz, foo Hint: try 'perf list syscalls:sys_enter_*' Hint: and: 'man syscalls' [root@zoo ~]# Reported-by:

Because we now propagate all evlist's cpu_maps and thread_map objects through all evsels, the perf_evsel__(nr_)cpus no longer need to be specific to stat object and check evlist and target objects. Signed-off-by:

Jiri Olsa authored
Propagate evlist's thread_map object through all the evsel objects. It'll be handy to access evsel's threads directly in following patches. The reason is there's no link from evsel to evlist which hold threads map now and evlist is not always available. Signed-off-by:

With commit: e1e455f4 (perf tools: Work around lack of sched_getcpu in glibc < 2.6), perf_bench numa mem with -c or -m option is not able to correctly calculate convergence. With the above commit, sched_getcpu always seems to return -1. The intention of commit e1e455f4 was to add a sched_getcpu in glibc < 2.6. Hence keep the sched_getcpu definition under an ifdef. This regression happened occurred between v4.0 and v4.1 Signed-off-by:

Fix failure to probe events on arm, the problem was introduced by commit 5a51fcd1 ("perf probe: Skip kernel symbols which is out of .text"). For some architectures, the '_etext' label is not in the .text section (in the .notes section for arm/arm64). Labels out of the .text section are not loaded as symbols and we get a zero value when looking up its addresses, which causes all events to be wrongly skipped. This patch skips checking the text address range when failing to get the address of '_etext' and thus fixes the problem. The problem can be reproduced on arm as follows: # perf probe --add='generic_perform_write' generic_perform_write+0 is out of .text, skip it. Probe point 'generic_perform_write' not found. Error: Failed to add events. After this patch: # perf probe --add='generic_perform_write' Added new event: probe:generic_perform_write (on generic_perform_write) You can now use it in all perf tools, such as: perf record -e probe:generic_perform_write -aR sleep 1 Signed-off-by:

When dumping events with 'perf report -D' the event print always starts with a newline (see dump_event()). Do the same with the "Aggregated stats" print so that it is not jammed up against the last event print. Signed-off-by:

Adrian Hunter authored
With 'perf report -D' the PERF_RECORD_FINISHED_ROUND event was printed without a newline, resulting in: 0x91a18 [0x8]: PERF_RECORD_FINISHED_ROUNDAggregated stats Other events print their details, but PERF_RECORD_FINISHED_ROUND doesn't have any so just add a print for a newline. Signed-off-by:

The Intel events use a dot to separate event name and unit mask. Allow dot in names in the scanner, and remove special handling of dot as EOF. Also remove the hack in jevents to replace dot with underscore. This way dotted events can be specified directly by the user. I'm not fully sure this change to the scanner is correct (what was the dot special case good for?), but I haven't found anything that breaks with it so far at least. Signed-off-by:

Pull x86 core updates from Ingo Molnar: "There were so many changes in the x86/asm, x86/apic and x86/mm topics in this cycle that the topical separation of -tip broke down somewhat - so the result is a more traditional architecture pull request, collected into the 'x86/core' topic. The topics were still maintained separately as far as possible, so bisectability and conceptual separation should still be pretty good - but there were a handful of merge points to avoid excessive dependencies (and conflicts) that would have been poorly tested in the end. The next cycle will hopefully be much more quiet (or at least will have fewer dependencies). The main changes in this cycle were: * x86/apic changes, with related IRQ core changes: (Jiang Liu, Thomas Gleixner) - This is the second and most intrusive part of changes to the x86 interrupt handling - full conversion to hierarchical interrupt domains: [IOAPIC domain] ----- | [MSI domain] --------[Remapping domain] ----- [ Vector domain ] | (optional) | [HPET MSI domain] ----- | | [DMAR domain] ----------------------------- | [Legacy domain] ----------------------------- This now reflects the actual hardware and allowed us to distangle the domain specific code from the underlying parent domain, which can be optional in the case of interrupt remapping. It's a clear separation of functionality and removes quite some duct tape constructs which plugged the remap code between ioapic/msi/hpet and the vector management. - Intel IOMMU IRQ remapping enhancements, to allow direct interrupt injection into guests (Feng Wu) * x86/asm changes: - Tons of cleanups and small speedups, micro-optimizations. This is in preparation to move a good chunk of the low level entry code from assembly to C code (Denys Vlasenko, Andy Lutomirski, Brian Gerst) - Moved all system entry related code to a new home under arch/x86/entry/ (Ingo Molnar) - Removal of the fragile and ugly CFI dwarf debuginfo annotations. Conversion to C will reintroduce many of them - but meanwhile they are only getting in the way, and the upstream kernel does not rely on them (Ingo Molnar) - NOP handling refinements. (Borislav Petkov) * x86/mm changes: - Big PAT and MTRR rework: making the code more robust and preparing to phase out exposing direct MTRR interfaces to drivers - in favor of using PAT driven interfaces (Toshi Kani, Luis R Rodriguez, Borislav Petkov) - New ioremap_wt()/set_memory_wt() interfaces to support Write-Through cached memory mappings. This is especially important for good performance on NVDIMM hardware (Toshi Kani) * x86/ras changes: - Add support for deferred errors on AMD (Aravind Gopalakrishnan) This is an important RAS feature which adds hardware support for poisoned data. That means roughly that the hardware marks data which it has detected as corrupted but wasn't able to correct, as poisoned data and raises an APIC interrupt to signal that in the form of a deferred error. It is the OS's responsibility then to take proper recovery action and thus prolonge system lifetime as far as possible. - Add support for Intel "Local MCE"s: upcoming CPUs will support CPU-local MCE interrupts, as opposed to the traditional system- wide broadcasted MCE interrupts (Ashok Raj) - Misc cleanups (Borislav Petkov) * x86/platform changes: - Intel Atom SoC updates ... and lots of other cleanups, fixlets and other changes - see the shortlog and the Git log for details" * 'x86-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (222 commits) x86/hpet: Use proper hpet device number for MSI allocation x86/hpet: Check for irq==0 when allocating hpet MSI interrupts x86/mm/pat, drivers/infiniband/ipath: Use arch_phys_wc_add() and require PAT disabled x86/mm/pat, drivers/media/ivtv: Use arch_phys_wc_add() and require PAT disabled x86/platform/intel/baytrail: Add comments about why we disabled HPET on Baytrail genirq: Prevent crash in irq_move_irq() genirq: Enhance irq_data_to_desc() to support hierarchy irqdomain iommu, x86: Properly handle posted interrupts for IOMMU hotplug iommu, x86: Provide irq_remapping_cap() interface iommu, x86: Setup Posted-Interrupts capability for Intel iommu iommu, x86: Add cap_pi_support() to detect VT-d PI capability iommu, x86: Avoid migrating VT-d posted interrupts iommu, x86: Save the mode (posted or remapped) of an IRTE iommu, x86: Implement irq_set_vcpu_affinity for intel_ir_chip iommu: dmar: Provide helper to copy shared irte fields iommu: dmar: Extend struct irte for VT-d Posted-Interrupts iommu: Add new member capability to struct irq_remap_ops x86/asm/entry/64: Disentangle error_entry/exit gsbase/ebx/usermode code x86/asm/entry/32: Shorten __audit_syscall_entry() args preparation x86/asm/entry/32: Explain reloading of registers after __audit_syscall_entry() ... -

Pull x86 FPU updates from Ingo Molnar: "This tree contains two main changes: - The big FPU code rewrite: wide reaching cleanups and reorganization that pulls all the FPU code together into a clean base in arch/x86/fpu/. The resulting code is leaner and faster, and much easier to understand. This enables future work to further simplify the FPU code (such as removing lazy FPU restores). By its nature these changes have a substantial regression risk: FPU code related bugs are long lived, because races are often subtle and bugs mask as user-space failures that are difficult to track back to kernel side backs. I'm aware of no unfixed (or even suspected) FPU related regression so far. - MPX support rework/fixes.
