When building kernel without CONFIG_FRAME_POINTER, gcc uses CFA (canonical frame address) for frame base. With this patch, perf probe just gets CFI (call frame information) from debuginfo and search corresponding CFA from the CFI. IOW, this allows perf probe works correctly on the kernel without CONFIG_FRAME_POINTER. <Before> ./perf probe -fn sched_slice:12 lw.weight Fatal: DW_OP 156 is not supported. (^^^ DW_OP_call_frame_cfa) <After> ./perf probe -fn sched_slice:12 lw.weight Add new event: probe:sched_slice (on sched_slice:12 with weight=lw.weight) Cc: Ingo Molnar <mingo@elte.hu> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Mike Galbraith <efault@gmx.de> Cc: Frederic Weisbecker <fweisbec@gmail.com> LKML-Reference: <20100412171728.3790.98217.stgit@localhost6.localdomain6> Signed-off-by: Masami Hiramatsu <mhiramat@redhat.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

Query the basic type information (byte-size and signed-flag) from debuginfo and pass that to kprobe-tracer.

Support basic types of integer (u8, u16, u32, u64, s8, s16, s32, s64) in kprobe tracer. With this patch, users can specify above basic types on each arguments after ':'. If omitted, the argument type is set as unsigned long (u32 or u64, arch-dependent). e.g. echo 'p account_system_time+0 hardirq_offset=%si:s32' > kprobe_events adds a probe recording hardirq_offset in signed-32bits value on the entry of account_system_time.

Set the last field name to the argument name when the argument is refering a data-structure member. e.g. ./perf probe --add 'vfs_read file->f_mode' Add new event: probe:vfs_read (on vfs_read with f_mode=file->f_mode) This probe records file->f_mode, but the argument name becomes "f_mode". This enables perf-trace command to parse trace event format correctly.

struct sort_entry has a callback named snprintf that turns an entry into a string result. But there are glibc versions that implement snprintf through a macro. The following expression is then going to get the snprintf call preprocessed: ent->snprintf(...) to finally end up in a build error: util/hist.c: Dans la fonction «hist_entry__snprintf» : util/hist.c:539: erreur: «struct sort_entry» has no member named «__builtin___snprintf_chk» To fix this, prepend struct sort_entry callbacks with an "se_" prefix.

The cpu/task clock events implement their own version of exclusion on top of exclude_user and exclude_kernel. The result is that when the event triggered in the kernel but we have exclude_kernel set, we try to rewind using task_pt_regs. There are two side effects of this: - we call task_pt_regs even on kernel threads, which doesn't give us the desired result. - if the event occured in the kernel, we shouldn't rewind to the user context. We want to actually ignore the event. get_irq_regs() will always give us the right interrupted context, so use its result and submit it to perf_exclude_context() that knows when an event must be ignored.

Each time a software event triggers, we need to walk through the entire list of events from the current cpu and task contexts to retrieve a running perf event that matches. We also need to check a matching perf event is actually counting. This walk is wasteful and makes the event fast path scaling down with a growing number of events running on the same contexts. To solve this, we store the running perf events in a hashlist to get an immediate access to them against their type:event_id when they trigger. v2: - Fix SWEVENT_HLIST_SIZE definition (and re-learn some basic maths along the way) - Only allocate hlist for online cpus, but keep track of the refcount on offline possible cpus too, so that we allocate it if needed when it becomes online. - Drop the kref use as it's not adapted to our tricks anymore. v3: - Fix bad refcount check (address instead of value). Thanks to Eric Dumazet who spotted this. - While exiting cpu, move the hlist release out of the IPI path to lock the hlist mutex sanely.

Parsing an option from the command line with OPT_BOOLEAN on a bool data type would not work on a big-endian machine due to the manner in which the boolean was being cast into an int and incremented. For example, running 'perf probe --list' on a PowerPC machine would fail to properly set the list_events bool and would therefore print out the usage information and terminate. This patch makes OPT_BOOLEAN work as expected with a bool datatype. For cases where the original OPT_BOOLEAN was intentionally being used to increment an int each time it was passed in on the command line, this patch introduces OPT_INCR with the old behaviour of OPT_BOOLEAN (the verbose variable is currently the only such example of this). I have reviewed every use of OPT_BOOLEAN to verify that a true C99 bool was passed. Where integers were used, I verified that they were only being used for boolean logic and changed them to bools to ensure that they would not be mistakenly used as ints. The major exception was the verbose variable which now uses OPT_INCR instead of OPT_BOOLEAN. Signed-off-by: Ian Munsie <imunsie@au.ibm.com> Acked-by: David S.

I don't claim to understand the tty layer, but it seems like hvc_open and hvc_close should be balanced in their kref reference counting. Right now we get a kref every call to hvc_open: if (hp->count++ > 0) { tty_kref_get(tty); <----- here spin_unlock_irqrestore(&hp->lock, flags); hvc_kick(); return 0; } /* else count == 0 */ tty->driver_data = hp; hp->tty = tty_kref_get(tty); <------ or here if hp->count was 0 But hvc_close has: tty_kref_get(tty); if (--hp->count == 0) { ... /* Put the ref obtained in hvc_open() */ tty_kref_put(tty); ... } tty_kref_put(tty); Since the outside kref get/put balance we only do a single kref_put when count reaches 0. The patch below changes things to call tty_kref_put once for every hvc_close call, and with that my machine boots fine.

rwsems can be used with IRQs disabled, particularily in early boot before IRQs are enabled. Currently the spin_unlock_irq() usage in the slow-patch will unconditionally enable interrupts and cause problems since interrupts are not yet initialized or enabled.

In NOMMU mode, the FRV segment handling is broken because KERNEL_DS == USER_DS. This causes tests of the following sort: /* don't pin down non-user-based iovecs */ if (segment_eq(get_fs(), KERNEL_DS)) return NULL; to malfunction. To fix this, make USER_DS the top of RAM instead of the top of the non-IO address space, and make KERNEL_DS one more than the top of the non-IO address space. Also get rid of FRV's __addr_ok() as nothing uses it.
