2007-09-16 Soren Sandmann <sandmann@daimi.au.dk>
* process.c (process_lookup_kernel_symbol): Add support for
looking up kernel symbols from /proc/kallsyms
* sysprof-text.c (dump_data): Print note that the file is being
saved.
* module/sysprof-module.[ch] (timer_notify): Send a copy of the
kernel stack to userspace.

2007-08-26 Soren Sandmann <sandmann@daimi.au.dk>
* profile.c (profile_get_size): Compute the size by simply summing
the size of the siblings. They are toplevel by definition, and
this works if the siblings for some reason has the same address.

2006-11-22 Soren Sandmann <sandmann@daimi.au.dk>
* profile.c (add_trace_to_tree): Move match to front
(add_trace_to_tree): Break as soon as a recursive call is found.
* stackstash.c (do_callback): Manual tail call optimization.
2006-11-02 Soren Sandmann <sandmann@daimi.au.dk>
Valgrind:
* binparser.c (bin_parser_free): Add this function
* elfparser.c (elf_parser_free): Call bin_parser_free()
* sysprof.c (compute_text_width, add_text): Plug leaks
* collector.c (add_trace_to_stash): Copy n_addresses to a stack
variable instead of reading it out of the mmap'ed area all the
time. (That way if there is an overrun, we won't write too much
into the address array).
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.

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.
2006-08-20 Soren Sandmann <sandmann@daimi.au.dk>
* process.h: Make process_lookup_symbol() return a string. Delete
process_lookup_symbol_with_filename().
* process.c (struct Process): Make "undefined" a string
(lookup_kernel_symbol): Return a string
(process_lookup_symbol): Return a string, not a symbol
* collector.c (unique_dup): Take a string instead of a
Symbol.
(lookup_symbol): Make sym a string instead of a Symbol.
* binfile.c (bin_symbol_get_name): New function.
* binfile.[ch] (struct BinSymbol): Rename Symbol to BinSymbol and
make it an opaque structure.
* binfile.[ch]: Remove unused symbol operations

not tail to the buffer.
Sun Jan 8 03:22:22 2006 Soeren Sandmann <sandmann@redhat.com>
* process.c (process_flush_caches): Resurrect this function.
* collector.c (collector_reset): Call it from here
Tue Dec 20 16:03:29 2005 Soeren Sandmann <sandmann@redhat.com>
* TODO: Updates
* sysprof-text.c (main): Make it try and load the module before
complaining.
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.
Sat Nov 12 19:44:43 2005 Søren Sandmann <sandmann@redhat.com>
* module/sysprof-module.c (read_frame): New function that uses
copy_from_user_inatomic() as check_user_pages_readable() has
disappeared in recent kernels.
* module/sysprof-module.c (timer_notify): Use it here.
* TODO: Updates
* configure.ac: Change the wording of the CVS HEAD warning as this
change seems to also have fixed the lockup with rawhide kernels.
Sun Nov 6 Soeren Sandmann <sandmann@redhat.com>
* TODO: updates
* collector.c (on_read): Only call back when a new sample actually
arrived.
* collector.c (collector_stop): close the filedescriptor

* sysprof.c (ensure_profile): Stop the collector.
* sysprof.c (on_reset_clicked): Stop the collector when state
becomes INITIAL.
Sun Nov 6 18:31:23 2005 Soeren Sandmann <sandmann@redhat.com>
* stackstash.c (stack_stash_foreach):
* stackstash.c (stack_node_foreach_trace): Make these function
call back with GLists rather than GSLists.
* profile.c (add_trace_to_tree): Iterate backwards instead of
copying the list.
Mon Oct 31 23:41:33 2005 Soeren Sandmann <sandmann@redhat.com>
* stackstash.h (struct StackNode): Add "total" field.
* stackstash.c (stack_stash_add_trace): Keep track of the
aggregate size.

computed total

from scratch.
