* Add the .call modifier to syscall entry probes.Przemyslaw Pawelczyk2009-10-122-704/+704
| | | | | | | | | | | | | | | | | | | | Inline functions do not have an indentifiable return point and require kernel built using VTA-enabled gcc to get tracking of variables. OTOH syscall functions are very rarely inlined (depending on the compiler mood), therefore filtering probes to include only non-inlined functions ensures consistent behavior between different kernels. This removes the problem of inaccessible variables in inlined syscalls that is described in comments #6-9 to PR5890 and gives us the status quo w.r.t. syscall probing, because before the commit solving PR10572 (b7478964) inline instances were masked anyway by non-inline ones. You can check whether you have inlined syscalls using following command: $ stap -l 'kernel.function("sys_*"),kernel.function("compat_sys_*")' \ 2>&1 -vvv | awk '/^selected inline/{print $5}' * tapset/syscalls.stp: Add .call to all entry probes. * tapset/syscalls2.stp: Ditto.

* indent tapset: make O(1) rather than O(n)Frank Ch. Eigler2009-10-021-5/+1
| | | | | * tapset/indent.stp (_generic_indent): Use "%-*s" instead of string concatenation loop.
* Actually indent_thread() is a very useful function, butBreno Leitao2009-10-011-4/+16
| | | | | | | | | | | | | | | | | | | | | | sometimes you're probing something that is not related to any task, as an interrupt function, and if the application changes during the interrupt, the indentation gets confused. For example: 0 swapper(0): -> neo_copy_data_from_queue_to_uart 69 a.out(7659): -> neo_parse_modem 74 a.out(7659): -> neo_param 14 swapper(0): <- neo_copy_data_from_queue_to_uart 83 a.out(7659): -> jsm_carrier 86 a.out(7659): <- jsm_carrier 0 swapper(0): -> neo_parse_modem 94 a.out(7659): <- jsm_tty_set_termios 8 swapper(0): <- neo_parse_modem So, I decided to create a simpler function that doesn't consider the task. Much of the idea of this implementation came from Frank(Thanks)
