- Subject: [PATCH 00/12] record btrace: prepare for a new trace format
- Authentication-results: sourceware.org; auth=none
This is the first part of a patch series that adds support for a new trace
format. The entire series consists of three parts:
- preparation (this)
- support live inferior tracing
- support trace in core files
Besides preparing for an additional trace format, this first part adds the
following functionality:
- allow the trace buffer size to be configured
- indicate errors as gaps in the trace
In order to motivate some patches (e.g. identifying the cpu or changing the
btrace_compute_ftrace parameters), I also send a work-in-progress version of the
second part that adds support for the new trace format. This patch is not part
of the series under review.
Markus Metzger (12):
btrace: add struct btrace_data
btrace: add format argument to supports_btrace
btrace, linux: add perf event buffer abstraction
record btrace: add configuration struct
record-btrace: add bts buffer size configuration option
btrace: update btrace_compute_ftrace parameters
btrace: extend struct btrace_insn
btrace: identify cpu
btrace: use the new cpu identifier
record-btrace: indicate gaps
configure: check for libipt
[wip] btrace: support Intel(R) Processor Trace
