From 29000b204d039bc1123027eba755329ab36a3dde Mon Sep 17 00:00:00 2001 From: drath Date: Tue, 14 Aug 2007 09:48:54 +0000 Subject: - reworked presto.c to allow use of either FTD2XX or libftdi (libftdi not functional yet). Configure option changed from --enable-presto to --enable-presto_ftd2xx and --enable-presto_libftdi - completed trace point support for use with ARM7/9 DCC - completed debug message output with support for HEX dumps (1, 2 or 4 byte quantities) - fixed bug in delete_debug_msg_receiver (thanks to Pavel Chromy) - fixed bug in image_add_section (thanks to Pavel Chromy) - at91sam7 sector erase reworked (thanks to Pavel Chromy) - merge consecutive sections during flash image write to work around possible section alignment issues with LPC2000 targets git-svn-id: svn://svn.berlios.de/openocd/trunk@194 b42882b7-edfa-0310-969c-e2dbd0fdcd60 --- src/target/trace.c | 109 ++++++++++++++++++++++++++++++++++++++++++++++++++--- 1 file changed, 104 insertions(+), 5 deletions(-) (limited to 'src/target/trace.c') diff --git a/src/target/trace.c b/src/target/trace.c index 3eec3d83..536e34a5 100644 --- a/src/target/trace.c +++ b/src/target/trace.c @@ -25,8 +25,76 @@ #include "log.h" #include "trace.h" #include "target.h" +#include "command.h" #include +#include +#include + +int trace_point(target_t *target, int number) +{ + trace_t *trace = target->trace_info; + + DEBUG("tracepoint: %i", number); + + if (number < trace->num_trace_points) + trace->trace_points[number].hit_counter++; + + if (trace->trace_history_size) + { + trace->trace_history[trace->trace_history_pos++] = number; + if (trace->trace_history_pos == trace->trace_history_size) + { + trace->trace_history_pos = 0; + trace->trace_history_overflowed = 1; + } + } + + return ERROR_OK; +} + +int handle_trace_point_command(struct command_context_s *cmd_ctx, char *cmd, char **args, int argc) +{ + target_t *target = get_current_target(cmd_ctx); + trace_t *trace = target->trace_info; + + if (argc == 0) + { + int i; + + for (i = 0; i < trace->num_trace_points; i++) + { + command_print(cmd_ctx, "trace point 0x%8.8x (%"PRIi64" times hit)", + trace->trace_points[i].address, + trace->trace_points[i].hit_counter); + } + + return ERROR_OK; + } + + if (!strcmp(args[0], "clear")) + { + if (trace->trace_points) + free(trace->trace_points); + trace->num_trace_points = 0; + trace->trace_points_size = 0; + + return ERROR_OK; + } + + /* resize array if necessary */ + if (!trace->trace_points || (trace->trace_points_size == trace->num_trace_points)) + { + trace->trace_points = realloc(trace->trace_points, sizeof(trace_point_t) * (trace->trace_points_size + 32)); + trace->trace_points_size += 32; + } + + trace->trace_points[trace->num_trace_points].address = strtoul(args[0], NULL, 0); + trace->trace_points[trace->num_trace_points].hit_counter = 0; + trace->num_trace_points++; + + return ERROR_OK; +} int handle_trace_history_command(struct command_context_s *cmd_ctx, char *cmd, char **args, int argc) { @@ -35,6 +103,15 @@ int handle_trace_history_command(struct command_context_s *cmd_ctx, char *cmd, c if (argc > 0) { + trace->trace_history_pos = 0; + trace->trace_history_overflowed = 0; + + if (!strcmp(args[0], "clear")) + { + /* clearing is implicit, we've just reset position anyway */ + return ERROR_OK; + } + if (trace->trace_history) free(trace->trace_history); @@ -46,24 +123,46 @@ int handle_trace_history_command(struct command_context_s *cmd_ctx, char *cmd, c else { int i; + int first = 0; + int last = trace->trace_history_pos; + + if (trace->trace_history_overflowed) + { + first = trace->trace_history_pos; + last = trace->trace_history_pos - 1; + } - for (i = 0; i < trace->trace_history_size; i++) + for (i = first; (i % trace->trace_history_size) != last; i++) { - if (trace->trace_history[i] < trace->num_trace_points) + if (trace->trace_history[i % trace->trace_history_size] < trace->num_trace_points) { u32 address; - address = trace->trace_points[trace->trace_history[i]].address; + address = trace->trace_points[trace->trace_history[i % trace->trace_history_size]].address; command_print(cmd_ctx, "trace point %i: 0x%8.8x", - trace->trace_history[i], + trace->trace_history[i % trace->trace_history_size], address); } else { - command_print(cmd_ctx, "trace point %i: -not defined-", trace->trace_history[i]); + command_print(cmd_ctx, "trace point %i: -not defined-", trace->trace_history[i % trace->trace_history_size]); } } } return ERROR_OK; } + +int trace_register_commands(struct command_context_s *cmd_ctx) +{ + command_t *trace_cmd = + register_command(cmd_ctx, NULL, "trace", NULL, COMMAND_ANY, "trace commands"); + + register_command(cmd_ctx, trace_cmd, "history", handle_trace_history_command, + COMMAND_EXEC, "display trace history, ['clear'] history or set [size]"); + + register_command(cmd_ctx, trace_cmd, "point", handle_trace_point_command, + COMMAND_EXEC, "display trace points, ['clear'] list of trace points, or add new tracepoint at [address]"); + + return ERROR_OK; +} -- cgit v1.2.3
