Subject: [PATCH v2 00/13] record btrace: prepare for a new trace format
Date: Thu, 20 Nov 2014 10:47:00 -0000 [thread overview]
Message-ID: <1416480444-9943-1-git-send-email-markus.t.metzger@intel.com> (raw)
Changes to v1:
- incorporated Pedro's comments
- moved btrace-common from common/ into nat/ and renamed to x86-btrace
- changed "btrace, linux: add perf event buffer abstraction" and
"[wip] btrace: support Intel(R) Processor Trace" to support
a new kernel interface: https://lkml.org/lkml/2014/11/14/292.
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 (13):
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: move and rename btrace-common
btrace: identify cpu
btrace: use the new cpu identifier
record-btrace: indicate gaps
configure: check for libipt
[wip] btrace: support Intel(R) Processor Trace
