Ubuntu now ships with module signing enabled by default.
Does the installation fail, or is it just a warning?
i don't know
....
lsmod | grep lttng
-> no module found
The modules will not be automatically loaded after being built and
installed. You have to launch lttng-sessiond (as root) for that. What
is the output of the following commands?
make
sudo make modules_install
sudo depmod -a
sudo lttng-sessiond &
lsmod | grep lttng

Hi,
I want to write a driver with trace events.
In the first step i compile the example trace-events-sample.c with the
makefile:
ifneq ($(KERNELRELEASE),)
obj-m := modul_trace-events-sample.o
modul_trace-events-sample-y := trace-events-sample.o
ccflags-y := -I$(src)
else
KDIR ?= /lib/modules/`uname -r`/build
default:
$(MAKE) -C $(KDIR) M=$$PWD
endif
now i get the modul_trace-events-sample.ko File.
now:
insmod modul_trace-events-sample.ko
lttng create
lttng enable-event -k -a
lttng start
...wait...
lttng stop
lttng destroy
now i look the result in the eclise viewer, but i found event
"trace_foo_bar" not in the session!
what am I doing wrong?
I use ubuntu 13.04 in a vmware
Thanks
