In order to differentiate source lines from asm line, print them with

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

But it requires final perf_gtk__show_annotations() to start processing

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.

Investigating the following gesture highlighted two slight implementation
errors with choosing which slots to report in which slot when multiple
contacts are present:
Action SGM AGM (MTB slot:Contact)
1. Touch contact 0 (0:0)
2. Touch contact 1 (0:0, 1:1)
3. Lift contact 0 (1:1)
4. Touch contacts 2,3 (0:2, 1:3)
In step 4, slot 1 was not being cleared first, which means the same
tracking ID was being used for reporting both the old contact 1 and the
new contact 3. This could result in "drumroll", where the old contact 1
would appear to suddenly jump to new finger 3 position.
Similarly, if contacts 2 & 3 are not detected at the same sample, step 4
is split into two:
Action SGM AGM (MTB slot:contact)
1. Touch contact 0 (0:0)
2. Touch contact 1 (0:0, 1:1)
3. Lift contact 0 (1:1)
4. Touch contact 2 (0:2, 1:1)
5. Touch contact 3 (0:2, 1:3)
In this case, there was also a bug. In step 4, when contact 1 moves from
SGM to AGM and contact 2 is first reported in SGM, slot 0 was actually
empty. So slot 0 can be used to report the new SGM (contact 0),
immediately. Since it was empty, contact 2 in slot 0 will get a new
tracking ID.

====================
VLAN filtering/VLAN aware bridge
Changes since v10
* Updated implemenation of ndo_fdb_del in emulex and qlogic drivers.
Changes since v9:
* series re-ordering so make functionality more distinct. Basic vlan
filtering is patches 1-4. Support for PVID/untagged vlans is patches
5 and 6. VLAN support for FDB/MDB is patches 7-11. Patch 12 is
still additional egress policy.
* Slight simplification to code that extracts the VID from skb. Since we
now depend on the vlan module, at the time of input skb_tci is guaranteed
to be set if the packet had 8021q header. We can simply refere to it.
* Changed the opaque 'parent' pointer from prior patches to a union so we
can be much more explicit in our assignments.
* Lots of additional testing with STP turned on. No issues were observed.
Changes since v8:
* Unified vlans_to_* calls into a single interface
* Fixed the rest of the issues report by Michal Miroslaw
* Fixed a bug where fdb entries were not created for all added vlans.
Changes since v7:
* Rebases on the latest net-next and removed the vlan wrapper patch from
the series.
* Fixed a crash in br_fdb_add/br_fdb_delete.
Changes since v6:
* VLANs are now stored in a VLAN bitmap per port. This allows for O(1)
lookup at ingress and egress. We simply check to see if the bit associated
with the vlan id is set in the map. The drawback to this approach is that
it wastes some space when there is only a small number of VLANs.
* In addition to the build time configuration option, VLAN filtering also has
a configuration paramter in sysfs. By default the filtering is turned off
and all traffic is permitted. When the filtring is turned on, we do strict
matching to the filter configured. Thus, if there is no configuration, all
packets are rejected. This was done to make the behavior more streight
forward. Without this (and if egress policy patch is rejected), the
decision for how to forward untagged traffic that was not filtered at ingress
is almost impossible to make. It would not be right to deliver to every
port that has PVID set as, each port may have a different PVID.
* Separate egress policy bitmap patch has been isolated and is provided last
in the series. This has been a more contentious piece of functionality and I
wanted to isolate it so that it could easily be dropped and not block the whole
series.
Changes since v5:
- Pulled VLAN filtering into its own file and made it a configuration options.
- Made new vlan filtering option dependent on VLAN_8021Q.
- Got rid of HW filter inlines and moved then vlan_core.c.
(All of the above suggested by Stephen Hemminger)
Changes since v4:
- Pull per-port vlan data into its own structures and give it to the bridge
device thus making bridge device behave like a regular port for vlan
configuration.
- Add a per-vlan 'untagged' bitmap that determins egress policy. If a port
is part of this bitmap, traffic egresses untagged.
- PVID is now used for ingress policy only. Incomming frames without VLAN tag
are assigned to the PVID vlan. Egress is determined via bitmap memberships.
- Allow for incremental config of a vlan. Now, PVID and untagged memberships
may be set on existing vlans. They however can NOT be cleared separately.
- VLAN deletion is now done via RTM_DELLINK command for PF_BRIDGE family.
This cleans up the netlink interface.
Changes since v3:
- Re-integrated compiler problems that got left out last time. Appologies.
- checkpatches.pl errors fixed
Changes since v2:
- Added inline functiosn to manimulate vlan hw filters and re-use in 8021q
and bridge code.
- Use rtnl_dereference (Michael Tsirkin)
- Remove synchronize_net() call (Eric Dumazet)
- Fix NULL ptr deref bug I introduced in br_ifinfo_notify.
Changes since v1:
- Fixed some forwarding bugs.
- Add vlan to local fdb entries. New local entries are created per vlan
to facilite correct forwarding to bridge interface.
- Allow configuration of vlans directly on the bridge master device
in addition to ports.
Changes since rfc v2:
- Per-port vlan bitmap is gone and is replaced with a vlan list.
- Added bridge vlan list, which is referenced by each port. Entries in
the birdge vlan list have port bitmap that shows which port are parts
of which vlan.
- Netlink API changes.
- Dropped sysfs support for now. If people think this is really usefull,
can add it back.
- Support for native/untagged vlans.
Changes since rfc v1:
- Comments addressed regarding formatting and RCU usage
- iocts have been removed and changed over the netlink interface.
- Added support of user added ndb entries.
- changed sysfs interface to export a bitmap. Also added a write interface.
I am not sure how much I like it, but it made my testing easier/faster. I
might change the write interface to take text instead of binary.

Add an ability to configure a separate "untagged" egress
policy to the VLAN information of the bridge. This superseeds PVID
policy and makes PVID ingress-only. The policy is configured with a
new flag and is represented as a port bitmap per vlan. Egress frames
with a VLAN id in "untagged" policy bitmap would egress

When VLAN is added to the port, a local fdb entry for that port
(the entry with the mac address of the port) is added for that
VLAN. This way we can correctly determine if the traffic
is for the bridge itself. If the address of the port changes,
we try to change all the local fdb entries we have for that port.

When a user adds bridge neighbors, allow him to specify VLAN id.
If the VLAN id is not specified, the neighbor will be added
for VLANs currently in the ports filter list. If no VLANs are
configured on the port, we use vlan 0 and only add 1 entry.

Add vlan_id to multicasts groups so that we know which vlan
each group belongs to and can correctly forward to appropriate vlan.
