The last sw period was not correctly updated on overflow and thus led to wrong distribution of events. We always need to properly initialize data.period in struct perf_sample_data. Signed-off-by:

Merge branch 'perf/annotate' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core Perf annotate browser improvements: - Get back the line separating the overheads from the disassembly, requested by Peter Zijlstra, Linus agreed now that it is a solid line and more column real state was harvested. Also it has the jump->arrow lines separated from it by the address/jump target column. - Don't change asm line color when toggling source code view. Requested by Peter Zijlstra.

The first column (columns in the near future) are for the per line event overhead(s), that only appear when they are not zero. To clearly separate it, add back a solid vertical line, with just one colour, not influenced by the per line overheads. Then have the addr/offset column, then optionally the dynamic (static in the future) jump->target arrows, if 'j' enables it. Then the instructions. Requested-by:

As ftrace function tracing would require modifying code that could be executed in NMI context, which is not stopped with stop_machine(), ftrace had to do a complex algorithm with various stages of setup and memory barriers to make it work. With the new breakpoint method, this is no longer required. The changes to the code can be done without any problem in NMI context, as well as without stop machine altogether. Remove the complex code as it is no longer needed. Also, a lot of the notrace annotations could be removed from the NMI code as it is now safe to trace them. With the exception of do_nmi itself, which does some special work to handle running in the debug stack. The breakpoint method can cause NMIs to double nest the debug stack if it's not setup properly, and that is done in do_nmi(), thus that function must not be traced.

This method changes x86 to add a breakpoint to the mcount locations instead of calling stop machine. Now that iret can be handled by NMIs, we perform the following to update code: 1) Add a breakpoint to all locations that will be modified 2) Sync all cores 3) Update all locations to be either a nop or call (except breakpoint op) 4) Sync all cores 5) Remove the breakpoint with the new code. 6) Sync all cores [ Added updates that Masami suggested: Use unlikely(modifying_ftrace_code) in int3 trap to keep kprobes efficient. Don't use NOTIFY_* in ftrace handler in int3 as it is not a notifier. ] Cc: H. Peter Anvin <hpa@zytor.com> Acked-by:

Arnaldo Carvalho de Melo authored

Merge tag 'perf-annotate-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core Annotation improvements: Now the default annotate browser uses a much more compact format, implementing suggestions made made by several people, notably Linus. Here is part of the new __list_del_entry() annotation: __list_del_entry 8.47 │ push %rbp 8.47 │ mov (%rdi),%rdx 20.34 │ mov $0xdead000000100100,%rcx 3.39 │ mov 0x8(%rdi),%rax 0.00 │ mov %rsp,%rbp 1.69 │ cmp %rcx,%rdx 0.00 │ je 43 1.69 │ mov $0xdead000000200200,%rcx 3.39 │ cmp %rcx,%rax 0.00 │ je a3 5.08 │ mov (%rax),%r8 18.64 │ cmp %r8,%rdi 0.00 │ jne 84 1.69 │ mov 0x8(%rdx),%r8 25.42 │ cmp %r8,%rdi 0.00 │ jne 65 1.69 │ mov %rax,0x8(%rdx) 0.00 │ mov %rdx,(%rax) 0.00 │ leaveq 0.00 │ retq 0.00 │ 43: mov %rdx,%r8 0.00 │ mov %rdi,%rcx 0.00 │ mov $0xffffffff817cd6a8,%rdx 0.00 │ mov $0x31,%esi 0.00 │ mov $0xffffffff817cd6e0,%rdi 0.00 │ xor %eax,%eax 0.00 │ callq ffffffff8104eab0 <warn_slowpath_fmt> 0.00 │ leaveq 0.00 │ retq 0.00 │ 65: mov %rdi,%rcx 0.00 │ mov $0xffffffff817cd780,%rdx 0.00 │ mov $0x3a,%esi 0.00 │ mov $0xffffffff817cd6e0,%rdi 0.00 │ xor %eax,%eax 0.00 │ callq ffffffff8104eab0 <warn_slowpath_fmt> 0.00 │ leaveq 0.00 │ retq The infrastructure is there to provide formatters for any instruction, like the one I'll do for call functions to elide the address. Further fixes on top of the first iteration: - Sometimes a jump points to an offset with no instructions, make the mark jump targets function handle that, for now just ignoring such jump targets, more investigation is needed to figure out how to cope with that. - Handle jump targets that are outside the function, for now just don't try to draw the connector arrow, right thing seems to be to mark this jump with a -> (right arrow) and handle it like a callq.

Add a debugfs entry under per_cpu/ folder for each cpu called buffer_size_kb to control the ring buffer size for each CPU independently. If the global file buffer_size_kb is used to set size, the individual ring buffers will be adjusted to the given size. The buffer_size_kb will report the common size to maintain backward compatibility. If the buffer_size_kb file under the per_cpu/ directory is used to change buffer size for a specific CPU, only the size of the respective ring buffer is updated. When tracing/buffer_size_kb is read, it reports 'X' to indicate that sizes of per_cpu ring buffers are not equivalent.

Currently, trace_printk() uses a single buffer to write into to calculate the size and format needed to save the trace. To do this safely in an SMP environment, a spin_lock() is taken to only allow one writer at a time to the buffer. But this could also affect what is being traced, and add synchronization that would not be there otherwise. Ideally, using percpu buffers would be useful, but since trace_printk() is only used in development, having per cpu buffers for something never used is a waste of space. Thus, the use of the trace_bprintk() format section is changed to be used for static fmts as well as dynamic ones. Then at boot up, we can check if the section that holds the trace_printk formats is non-empty, and if it does contain something, then we know a trace_printk() has been added to the kernel. At this time the trace_printk per cpu buffers are allocated. A check is also done at module load time in case a module is added that contains a trace_printk(). Once the buffers are allocated, they are never freed. If you use a trace_printk() then you should know what you are doing. A buffer is made for each type of context: normal softirq irq nmi The context is checked and the appropriate buffer is used. This allows for totally lockless usage of trace_printk(), and they no longer even disable interrupts. Requested-by:
