* stackstash.h (struct StackNode): Add "total" field.
* stackstash.c (stack_stash_add_trace): Keep track of the
aggregate size.
* profile.c (profile_get_size): Sum the totals of the siblings
instead of all the children.
* profile.c (build_object_list): Correctly compute obj->self
* profile.c (profile_load): Don't ignore the node->total field.
* profile.c (serialize_call_tree): Save node->total instead of the
computed total
* profile.c (compute_total): Use n->total instead of computing it
from scratch.
* profile.c: Remove unused sum_children() function.
* TODO: Updates
* process.c (process_get_from_pid): Plug leak.
Tue Sep 27 01:33:33 2005 Soeren Sandmann <sandmann@redhat.com>
* process.c (process_lookup_symbol): If the address is 0x01, treat
as kernel, regardless of whether we have a map for that address or
not.
* module/sysprof-module.c (timer_notify): Take a stack trace of
the current process, even when we are in kernel mode. This way we
can assign kernel activity to individual user space stacktraces.
* TODO: updates.
Tue Aug 30 16:57:33 2005 Søren Sandmann <sandmann@redhat.com>
* configure.ac: Complain if we can't find /lib/modules/`uname
-r`/build/Makefile.
* process.c (process_lookup_symbol): Take an address of 0x1 to
mean "in kernel".
* module/sysprof-module.c (timer_notify): When reporting in-kernel
time, give the current pid instead of -1.
* TODO: 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.
Tue Apr 5 23:01:02 2005 Søren Sandmann <sandmann@redhat.com>
* binfile.c (read_symbols): Put back the weird loop, and stop
pretending I understand this. This time use SEC_ALLOC instead of
SEC_LOAD.
Tue Apr 5 20:13:44 2005 Søren Sandmann <sandmann@redhat.com>
* process.c (process_ensure_map): Add commented out debug spew.
* process.c (process_lookup_symbol): Remove all should_offset()
function and all references to it.
* binfile.c (bin_file_lookup_symbol): Document that address must
be in file coordinates.
* binfile.c (read_symbols): Remove misguided code that tried to
guess the load address of the file. Instead, do all computations
in "file coordinates". Also fix a memory leak. Add commented out
debug spew.
* binfile.c (separate_debug_file_exists): Fix signedness
Thu Mar 31 19:51:51 2005 Søren Sandmann <sandmann@redhat.com>
* sysprof-module.c (do_generate): Walk all threads, not just all
processes.
* TODO: Add disk profiling ideas
Wed Mar 2 23:39:50 2005 Soeren Sandmann <sandmann@redhat.com>
* profile.[ch], sfile.[ch]: Experiment with a
file-format-description format.
* sysprof.c: Add commented out code using /proc/ based
timeout.
