perf tools: Add facility to export data in database-friendly way This patch introduces an abstraction for exporting sample data in a database-friendly way. The abstraction does not implement the actual output. A subsequent patch takes this facility into use for extending the script interface. The abstraction is needed because static data like symbols, dsos, comms etc need to be exported only once. That means allocating them a unique identifier and recording it on each structure. The member 'db_id' is used for that. 'db_id' is just a 64-bit sequence number. Exporting centres around the db_export__sample() function which exports the associated data structures if they have not yet been allocated a db_id.

perf script: Enable db export to output sampled callchains This change enables the db export api to export callchains. This is accomplished by adding callchains obtained from samples to the call_path_root structure and exporting them via the current call path export API. While the current API does support exporting call paths, this is not supported when sampling. This commit addresses that missing feature by allowing the export of call paths when callchains are present in samples. Summary: - This feature is activated by initializing the call_path_root member inside the db_export structure to a non-null value. - Callchains are resolved with thread__resolve_callchain() and then stored and exported by adding a call path under call path root. - Symbol and DSO for each callchain node are exported via db_ids_from_al() This commit puts in place infrastructure to be used by subsequent commits, and by itself, does not introduce any user-visible changes.

perf tools: Refactor code to move call path handling out of thread-stack Move the call path handling code out of thread-stack.c and thread-stack.h to allow other components that are not part of thread-stack to create call paths. Summary: - Create call-path.c and call-path.h and add them to the build. - Move all call path related code out of thread-stack.c and thread-stack.h and into call-path.c and call-path.h. - A small subset of structures and functions are now visible through call-path.h, which is required for thread-stack.c to continue to compile. This change is a prerequisite for subsequent patches in this change set and by itself contains no user-visible changes.

The abstraction does not implement the actual output. A subsequent patch takes this facility into use for extending the script interface.

perf symbols: Unify symbol maps Remove the split of symbol tables for data (MAP__VARIABLE) and for functions (MAP__FUNCTION), its unneeded and there were various places doing two lookups to find a symbol, so simplify this. We still will consider only the symbols that matched the filters in place, i.e. see the (elf_(sec,sym)|symbol_type)__filter() routines in the patch, just so that we consider only the same symbols as before, to reduce the possibility of regressions. All the tests on 50-something build environments, in varios versions of lots of distros and cross build environments were performed without build regressions, as usual with all pull requests the other tests were also performed: 'perf test' and 'make -C tools/perf build-test'. Also this was done at a great granularity so that regressions can be bisected more easily.

perf tools: Add facility to export data in database-friendly way This patch introduces an abstraction for exporting sample data in a database-friendly way. The abstraction does not implement the actual output. A subsequent patch takes this facility into use for extending the script interface. The abstraction is needed because static data like symbols, dsos, comms etc need to be exported only once. That means allocating them a unique identifier and recording it on each structure. The member 'db_id' is used for that. 'db_id' is just a 64-bit sequence number. Exporting centres around the db_export__sample() function which exports the associated data structures if they have not yet been allocated a db_id.

perf script: Enable db export to output sampled callchains This change enables the db export api to export callchains. This is accomplished by adding callchains obtained from samples to the call_path_root structure and exporting them via the current call path export API. While the current API does support exporting call paths, this is not supported when sampling. This commit addresses that missing feature by allowing the export of call paths when callchains are present in samples. Summary: - This feature is activated by initializing the call_path_root member inside the db_export structure to a non-null value. - Callchains are resolved with thread__resolve_callchain() and then stored and exported by adding a call path under call path root. - Symbol and DSO for each callchain node are exported via db_ids_from_al() This commit puts in place infrastructure to be used by subsequent commits, and by itself, does not introduce any user-visible changes.

While callchains themselves are nice to have, being able to associate them with samples makes them much more useful, and can allow for such things as determining how much cumulative time is spent in a particular function. This information is normally possible to get from the call return processor. However, when doing normal sampling, call/return information is not available, thus necessitating the need for associating samples directly with call paths.

perf tools: Add facility to export data in database-friendly way This patch introduces an abstraction for exporting sample data in a database-friendly way. The abstraction does not implement the actual output. A subsequent patch takes this facility into use for extending the script interface. The abstraction is needed because static data like symbols, dsos, comms etc need to be exported only once. That means allocating them a unique identifier and recording it on each structure. The member 'db_id' is used for that. 'db_id' is just a 64-bit sequence number. Exporting centres around the db_export__sample() function which exports the associated data structures if they have not yet been allocated a db_id.

perf db-export: Add trace begin / end branch type variants Add branch types to cover different combinations with "trace begin" or "trace end". Previously, the Intel PT decoder would indicate begin / end by a branch from / to zero. That hides useful information, in particular when a trace ends with a call. Before remedying that, prepare the database export to export branch types with more combinations that include trace begin / end. In those cases extend the descriptions to include 'trace begin' and 'trace end' separately.
