* | hlist: drop the node parameter from iteratorsSasha Levin2013-02-281-2/+1

I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually. The semantic patch which is mostly the work of Peter Senna Tschudin is here: @@ iterator name hlist_for_each_entry, hlist_for_each_entry_continue, hlist_for_each_entry_from, hlist_for_each_entry_rcu, hlist_for_each_entry_rcu_bh, hlist_for_each_entry_continue_rcu_bh, for_each_busy_worker, ax25_uid_for_each, ax25_for_each, inet_bind_bucket_for_each, sctp_for_each_hentry, sk_for_each, sk_for_each_rcu, sk_for_each_from, sk_for_each_safe, sk_for_each_bound, hlist_for_each_entry_safe, hlist_for_each_entry_continue_rcu, nr_neigh_for_each, nr_neigh_for_each_safe, nr_node_for_each, nr_node_for_each_safe, for_each_gfn_indirect_valid_sp, for_each_gfn_sp, for_each_host; type T; expression a,c,d,e; identifier b; statement S; @@ -T b; <+... when != b ( hlist_for_each_entry(a, - b, c, d) S | hlist_for_each_entry_continue(a, - b, c) S | hlist_for_each_entry_from(a, - b, c) S | hlist_for_each_entry_rcu(a, - b, c, d) S | hlist_for_each_entry_rcu_bh(a, - b, c, d) S | hlist_for_each_entry_continue_rcu_bh(a, - b, c) S | for_each_busy_worker(a, c, - b, d) S | ax25_uid_for_each(a, - b, c) S | ax25_for_each(a, - b, c) S | inet_bind_bucket_for_each(a, - b, c) S | sctp_for_each_hentry(a, - b, c) S | sk_for_each(a, - b, c) S | sk_for_each_rcu(a, - b, c) S | sk_for_each_from -(a, b) +(a) S + sk_for_each_from(a) S | sk_for_each_safe(a, - b, c, d) S | sk_for_each_bound(a, - b, c) S | hlist_for_each_entry_safe(a, - b, c, d, e) S | hlist_for_each_entry_continue_rcu(a, - b, c) S | nr_neigh_for_each(a, - b, c) S | nr_neigh_for_each_safe(a, - b, c, d) S | nr_node_for_each(a, - b, c) S | nr_node_for_each_safe(a, - b, c, d) S | - for_each_gfn_sp(a, c, d, b) S + for_each_gfn_sp(a, c, d) S | - for_each_gfn_indirect_valid_sp(a, c, d, b) S + for_each_gfn_indirect_valid_sp(a, c, d) S | for_each_host(a, - b, c) S | for_each_host_safe(a, - b, c, d) S | for_each_mesh_entry(a, - b, c, d) S ) ...+> [akpm@linux-foundation.org: drop bogus change from net/ipv4/raw.c] [akpm@linux-foundation.org: drop bogus hunk from net/ipv6/raw.c] [akpm@linux-foundation.org: checkpatch fixes] [akpm@linux-foundation.org: fix warnings] [akpm@linux-foudnation.org: redo intrusive kvm changes] Tested-by: Peter Senna Tschudin <peter.senna@gmail.com> Acked-by: Paul E.

* perf gtk/annotate: Support multiple event annotationNamhyung Kim2013-02-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | Show multiple annotation result for each evsel. Each result represents the most frquently sampled symbol/function for the evsel and it will be shown in a tab window. For this add a reference to main container (notebook) to the pgctx. At the first call to annotate browser, hist_entry__find_annotations() will setup a new browser, and next calls will add new tabs to the browser. But it requires final perf_gtk__show_annotations() to start processing GUI events.

* perf annotate: Fix warning message on a missing vmlinuxNamhyung Kim2013-02-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When perf annotate runs with no vmlinux file it cannot annotate kernel symbols because the kallsyms only provides symbol addresses. So it recommends to run perf buildid-cache to install proper vmlinux image. But running perf buildid-cache -av vmlinux as the message gives me a following error: $ perf buildid-cache -av /home/namhyung/build/kernel/vmlinux Couldn't add v: No such file or directory Since the -a option receives a parameter, 'v' should not be after the option. In addition -a option is not work for this case since the build-id cache already has a kallsyms with same build-id so it'll fail with EEXIST. Use recently added -u (--update) option for it.

* perf tools: Fix calloc argument orderingPaul Gortmaker2013-02-062-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | A sweep of the kernel for regex "kcalloc(sizeof" turned up 2 reversed args, fixed in commit d3d09e18203dba16a9dbdb2b4cc673d90748cdd1 ("EDAC: Fix kcalloc argument order") and also fixed in the networking commit a1b1add07fa794974573d93483d68e373edfe7bd ("gro: Fix kcalloc argument order"). I know that was the regex used, because on seeing the 1st of these changes, I wondered "how many other instances of this are there" and I happened to just use "calloc(sizeof" as a regex and it in turn found these additional reversed args instances in the perf code. In the kcalloc cases, the changes are cosmetic, since the numbers are simply multiplied. I had no desire to go data mining in userspace to see if the same thing held true there, however.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I am getting segfaults *after* the time sorting of perf samples where the event type is off the charts: (gdb) bt \#0 0x0807b1b2 in hists__inc_nr_events (hists=0x80a99c4, type=1163281902) at util/hist.c:1225 \#1 0x08070795 in perf_session_deliver_event (session=0x80a9b90, event=0xf7a6aff8, sample=0xffffc318, tool=0xffffc520, file_offset=0) at util/session.c:884 \#2 0x0806f9b9 in flush_sample_queue (s=0x80a9b90, tool=0xffffc520) at util/session.c:555 \#3 0x0806fc53 in process_finished_round (tool=0xffffc520, event=0x0, session=0x80a9b90) at util/session.c:645 This is bizarre because the event has already been processed once -- before it was added to the samples queue -- and the event was found to be sane at that time. There seem to be 2 causes: 1. perf_evlist__mmap_read updates the read location even though there are outstanding references to events sitting in the mmap buffers via the ordered samples queue. 2. There is a single evlist->event_copy for all evlist entries. event_copy is used to handle an event wrapping at the mmap buffer boundary. This patch addresses the second problem - making event_copy local to each perf_mmap. With this change my highly repeatable use case no longer fails. The first problem is much more complicated and will be the subject of a future patch.

* perf sort: Drop ip_[lr] arguments from _sort__sym_cmp()Namhyung Kim2013-02-061-17/+6
| | | | | | | | | | | | | | | | | | | | | | | Current _sort__sym_cmp() function is used for comparing symbols between two hist entries on symbol, symbol_from and symbol_to sort keys. Those functions pass addresses of symbols but it's meaningless since it gets over-written inside of the _sort__sym_cmp function to a start address of the symbol. So just get rid of them. This might cause a difference than prior output for branch stacks since it seems not using start address of the symbol but branch address. However AFAICS it'd be same as it gets overwritten anyway. Also remove redundant part of code in sort__sym_cmp().
