The file name will be 'power' with a mode of 0644 (-rw-r--r--).
+Word of warning: While the kernel allows device_create_file() and
+device_remove_file() to be called on a device at any time, userspace has
+strict expectations on when attributes get created. When a new device is
+registered in the kernel, a uevent is generated to notify userspace (like
+udev) that a new device is available. If attributes are added after the
+device is registered, then userspace won't get notified and userspace will
+not know about the new attributes.
+
+This is important for device driver that need to publish additional
+attributes for a device at driver probe time. If the device driver simply
+calls device_create_file() on the device structure passed to it, then
+userspace will never be notified of the new attributes. Instead, it should
+probably use class_create() and class->dev_attrs to set up a list of
+desired attributes in the modules_init function, and then in the .probe()
+hook, and then use device_create() to create a new device as a child
+of the probed device. The new device will generate a new uevent and
+properly advertise the new attributes to userspace.
+
+For example, if a driver wanted to add the following attributes:
+struct device_attribute mydriver_attribs[] = {
+ __ATTR(port_count, 0444, port_count_show),
+ __ATTR(serial_number, 0444, serial_number_show),
+ NULL
+};
+
+Then in the module init function is would do:
+ mydriver_class = class_create(THIS_MODULE, "my_attrs");
+ mydriver_class.dev_attr = mydriver_attribs;
+
+And assuming 'dev' is the struct device passed into the probe hook, the driver
+probe function would do something like:
+ create_device(&mydriver_class, dev, chrdev, &private_data, "my_name");

Ftrace uses the debugfs file system to hold the control files as
well as the files to display output.
-To mount the debugfs system:
+When debugfs is configured into the kernel (which selecting any ftrace
+option will do) the directory /sys/kernel/debug will be created. To mount
+this directory, you can add to your /etc/fstab file:
- # mkdir /debug
- # mount -t debugfs nodev /debug
+ debugfs /sys/kernel/debug debugfs defaults 0 0
-( Note: it is more common to mount at /sys/kernel/debug, but for
- simplicity this document will use /debug)
+Or you can mount it at run time with:
+
+ mount -t debugfs nodev /sys/kernel/debug
+
+For quicker access to that directory you may want to make a soft link to
+it:
+
+ ln -s /sys/kernel/debug /debug
+
+Any selected ftrace option will also create a directory called tracing
+within the debugfs. The rest of the document will assume that you are in
+the ftrace directory (cd /sys/kernel/debug/tracing) and will only concentrate
+on the files within that directory and not distract from the content with
+the extended "/sys/kernel/debug/tracing" path name.

Check that the driver you are about to trace is not loaded.
Activate mmiotrace (requires root privileges):
-$ echo mmiotrace > /debug/tracing/current_tracer
+$ echo mmiotrace > /sys/kernel/debug/tracing/current_tracer
Start storing the trace:
-$ cat /debug/tracing/trace_pipe > mydump.txt &
+$ cat /sys/kernel/debug/tracing/trace_pipe > mydump.txt &
The 'cat' process should stay running (sleeping) in the background.
Load the driver you want to trace and use it. Mmiotrace will only catch MMIO
accesses to areas that are ioremapped while mmiotrace is active.
During tracing you can place comments (markers) into the trace by
-$ echo "X is up" > /debug/tracing/trace_marker
+$ echo "X is up" > /sys/kernel/debug/tracing/trace_marker
This makes it easier to see which part of the (huge) trace corresponds to
which action. It is recommended to place descriptive markers about what you
do.
Shut down mmiotrace (requires root privileges):
-$ echo nop > /debug/tracing/current_tracer
+$ echo nop > /sys/kernel/debug/tracing/current_tracer
The 'cat' process exits. If it does not, kill it by issuing 'fg' command and
pressing ctrl+c.
