* Cleanup.David Smith2009-06-181-129/+0
| | | | | | * runtime/print_old.c: Removed unneeded file. * runtime/print_flush.c: Renamed from print_new.c * runtime/print.c: Includes print_flush.c (instead of print_new.c).
* Transports now export their state.David Smith2009-06-181-3/+2
| | | | | | | | | | | | | | * runtime/transport/transport.h: Added prototype for _stp_transport_get_state(). * runtime/transport/relay_v2.c (_stp_transport_get_state): New function. * runtime/transport/relayfs.c (_stp_transport_get_state): Ditto. * runtime/transport/ring_buffer.c (_stp_transport_data_fs_init): Sets state. (_stp_transport_data_fs_start): Ditto. (_stp_transport_data_fs_stop): Ditto. (_stp_transport_get_state): Returns state. * runtime/print_new.c (stp_print_flush): Checks transport state before trying to flush.
* Start at supporting the original transport (STP_TRANSPORT_VERSION=1).David Smith2009-05-121-0/+9
| | | | | | | | | * runtime/print.c: Only use print_new.c. * runtime/print_new.c (stp_print_flush): Add STP_TRANSPORT_VERSION 1 support. * runtime/transport/transport.c: Removed inclusion of procfs.c. * runtime/transport/procfs.c (_stp_proc_read): Adapt to new interface. (_stp_proc_write): Ditto. * runtime/transport/relayfs.c: Ditto.
* Hid details of internal ring_buffer.c structure.David Smith2009-05-071-5/+8
| | | | | | | | | * runtime/print_new.c (stp_print_flush): Calls _stp_data_entry_data() to get data pointer. * runtime/transport/transport.h: Removed _stp_entry definition. Added _stp_data_entry_data() declaration. * runtime/transport/ring_buffer.c: Uses new _stp_data_entry structure. (_stp_data_entry_data): Added.
* 2009-03-31 David Smith <dsmith@redhat.com>David Smith2009-03-311-95/+37
| | | | | | | | | | | | * print_new.c (stp_print_flush): Pushed MAX_RESERVE logic down to _stp_data_write_reserve(). Now just keeps calling _stp_data_write_reserve() until it has written the entire print buffer. * transport/ring_buffer.c (_stp_data_write_reserve): Breaks large reserve requests down into smaller ones for better buffer use. Returns the number of bytes reserved. * transport/transport.h: Updated _stp_data_write_reserve() prototype.

| | | | * print_new.c: Whitespace/indent changes only.
* Working bulkmode support.David Smith2009-03-131-6/+91
| | | | | | | | | | | | 2009-03-13 David Smith <dsmith@redhat.com> * print_new.c (stp_print_flush): Added bulkmode support for new transport. * transport/ring_buffer.c (__stp_find_next_entry): Fixed syntax error in bulkmode code. (_stp_transport_data_fs_init): Changed 'for_each_possible_cpu()' to 'for_each_online_cpu()' so that non-online cpu's won't have a trace file created.
* Small update.David Smith2009-03-111-1/+1
| | | | | | | | 2009-03-11 David Smith <dsmith@redhat.com> * print_new.c (stp_print_flush): Updated MAX_RESERVE_SIZE. * transport/ring_buffer.c (__stp_alloc_ring_buffer): Reserves more space.
* Handles polling and breaks down large buffers.David Smith2009-03-111-1/+29
| | | | | | | | | | | | 2009-03-11 David Smith <dsmith@redhat.com> * print_new.c (stp_print_flush): Breaks up the buffer into smaller pieces (since the ring_buffer likes lots of small events, not one large one). * transport/ring_buffer.c (__stp_alloc_ring_buffer): Reserves space for struct _stp_entry. (_stp_data_poll_trace): New function. (_stp_data_write_commit): Wakes up any tasks waiting on data.
* First working version that actually produces output.David Smith2009-03-091-8/+9
| | | | | | | | | | | | | | | | | | | | | | | 2009-03-09 David Smith <dsmith@redhat.com> * print_new.c (stp_print_flush): Calls _stp_data_write_reserve() and _stp_data_write_commit(). * transport/ring_buffer.c (__stp_alloc_ring_buffer): Sets up a default buffer size of STP_BUFFER_SIZE; (trace_seq_reset): New function. (peek_next_entry): New function. (__find_next_entry): New function. (find_next_entry_inc): New function. (_stp_data_read_trace): Uses find_next_entry_inc() to get the next entry, then calls _stp_entry_to_user() to copy it to the user's buffer, then calls ring_buffer_consume() to consume it. (_stp_data_write_reserve): New function. (_stp_data_write_commit): New function. * transport/transport.c (_stp_transport_close): Calls functions that were ifdef'ed out. * transport/transport.h (struct _stp_entry): Added _stp_entry definition and _stp_data_write_reserve()/_stp_data_write_commit() prototypes.
* More cleanup.David Smith2009-02-251-0/+4
| | | | | | | | | | | | | | | | 2009-02-25 David Smith <dsmith@redhat.com> * debug.h: Removed unused variable '_stp_transport_state'. * print_new.c (stp_print_flush): Ifdef'ed out call to utt_reserve(). * runtime.h: Added _stp_warn() prototype. * transport/control.c: Includes control.h, mempool.c, and symbols.c. Renamed '_stp_attached' to '_stp_ctl_attached'. * transport/control.h: Removed _stp_pool_q declaration. * transport/debugfs.c (_stp_register_ctl_channel_fs): Uses _stp_get_module_dir(). * transport/transport.c: Cleanup. * transport/transport.h: Ditto.
* Major hacking to minimal config.David Smith2009-02-241-2/+3

(utt_reserve): Ifdef'ed out guts.
* Use 'static' as much as possibleJosh Stone2009-01-281-1/+1
| | | | | | | | | | This change just inserts 'static' on runtime, tapset, and generated C functions and globals, so the compiler can do a better job of optimizing. My tests with small scripts show ~10% reduction in compile time and ~20% reduction in module size. Larger scripts may show less benefit, but I expect purely positive results.
