Hi List,
I am trying to use ftrace on a P2020 board, using the following :
- Linux 2.6.35-11
- Xenomai 2.5.5.1 (or 2.5.6, same problem)
- ipipe 2.12-01
I launch it using :
$ mkdir /tmp/debug
$ mount -t debugfs nodev /tmp/debug
$ cd /tmp/debug/tracing
$ echo function_graph current_tracer

Yes, ipipe tracing works.
When it is the case, BTW, Here is the result of echoing a new tracer :
$cat max

This patch adds a class driver for raw Ethernet drivers under
Xenomai. The goal is to support industrial protocols such as EtherCAT
and IEC 61850, where the stack is a user space program needing
direct access at the packet level. The class driver offers interfaces
for registration, buffer
This patch adds a class driver for sending and receiving raw Ethernet
packets over a character device interface.

This commit adjusts the code to use the second hardware receive queue.
The idea is to keep the first queue open for later use as a fast path
for real time Ethernet packets.
Note that this patch relies on the specific filer capabilities of eTSEC

*** Applies to ipipe-2.6.36-powerpc-2.12-03
This patch provides an example driver for the raw packet interface.
Much of the code is copy/paste from the main gainfar driver. The patch
uses the hardware priority queues of the P2020 to make a fast path for
real time traffic. Note this might not work
