4dd37d092c Communicate traces to userspace through shared memory instead of copying. 
2006-10-22  Soren Sandmann <sandmann@daimi.au.dk>

	Communicate traces to userspace through shared memory instead of
	copying.

	* module/sysprof-module.c: Store the traces in a SysprofMmapArea.
	(sysprof_mmap): Implement this method.
	(sysprof_nopage): Implement this.
	(sysprof_read): Just reset the tail pointer and return zero.

	* module/sysprof-module.h (struct SysprofMmapArea): New
	structure.

	* collector.c (collector_stop): Unmap the device
	(in_dead_period): New function
	(on_read): Read the traces out of mmap()ed area instead of reading
	them. Call read() to prevent poll() from firing.
	(struct Collector): New members map_area and current.

	* Makefile.am (insert-module): Prefix modprobe with /sbin

	* collector.c (open_fd): mmap() the sysprof device.

ad5ffd749b Dist and install udev rule. 
2005-12-20  Kristian Høgsberg  <krh@redhat.com>

        * Makefile.am: Dist and install udev rule.

        * collector.c: (open_fd):
        * sysprof-text.c: (no_module):
        * sysprof.c: (on_start_toggled): Update device filename.

        * 60-sysprof.rules: New udev rule file to set permissions for
        sysprof char device.

        * module/sysprof-module.c: Switch kernel module to use a misc char
        device instead.  Start and stop the timer on device open and
        close instead of module load and unload.

18abd9e1e6 Updates 
Sat Jun 18 22:45:04 2005  Søren Sandmann  <sandmann@redhat.com>

	* TODO: Updates

	* configure.ac: Check for Linux 2.6.11

	* process.c (get_pidname): Present pid=-1 as [kernel].

	* module/sysprof-module.c: Use register_timer_hook() instead of
	a kernel timer. Set trace.pid to -1 if interrupt happens in
	kernel.

71db050480 Auto*ify. 
Sat May 14 15:49:52 2005  Søren Sandmann  <sandmann@redhat.com>

	Auto*ify.

	* TODO: updates

	* AUTHORS, INSTALL, Makefile.am, NEWS, configure.ac: New files

	* module/Makefile: New file

	* module/sysprof-module.c, module/sysprof-module.h: Move these
	files to their own directy, as the kernel build system does not
	work very well with auto*.

	* sysprof.c, autogen.sh: Some auto* changes.
