[PATCH v2 0/3] perf cs-etm: Handle valid-but-zero timestamps

by James Clark

This patchset is an alternate solution to the original: "[RFC PATCH] perf cs-etm: Handle valid-but-zero timestamps". It uses the existing Z option to --itrace instead of modifying the behaviour of the cs_etm__etmq_get_timestamp() function. Using timeless mode is equivalent to ignoring 0 timestamps, as suggested by Mike and Leo. It applies on top of "[PATCH v3 0/2] perf cs-etm: Set time on synthesised samples to preserve ordering" James Clark (3): perf cs-etm: Move synth_opts initialisation perf cs-etm: Start reading 'Z' --itrace option perf cs-etm: Prevent and warn on underflows during timestamp calculation. .../perf/util/cs-etm-decoder/cs-etm-decoder.c | 45 ++++++++++++++----- tools/perf/util/cs-etm.c | 20 +++++---- 2 files changed, 46 insertions(+), 19 deletions(-) -- 2.28.0

[PATCH v2 00/40] Use ASCII subset instead of UTF-8 alternate symbols

by Mauro Carvalho Chehab

This series contain basically a cleanup from all those years of converting files to ReST. During the conversion period, several tools like LaTeX, pandoc, DocBook and some specially-written scripts were used in order to convert existing documents. Such conversion tools - plus some text editor like LibreOffice or similar - have a set of rules that turns some typed ASCII characters into UTF-8 alternatives, for instance converting commas into curly commas and adding non-breakable spaces. All of those are meant to produce better results when the text is displayed in HTML or PDF formats. While it is perfectly fine to use UTF-8 characters in Linux, and specially at the documentation, it is better to stick to the ASCII subset on such particular case, due to a couple of reasons: 1. it makes life easier for tools like grep; 2. they easier to edit with the some commonly used text/source code editors. Also, Sphinx already do such conversion automatically outside literal blocks, as described at: https://docutils.sourceforge.io/docs/user/smartquotes.html In this series, the following UTF-8 symbols are replaced: - U+00a0 (' '): NO-BREAK SPACE - U+00ad (''): SOFT HYPHEN - U+00b4 ('´'): ACUTE ACCENT - U+00d7 ('×'): MULTIPLICATION SIGN - U+2010 ('‐'): HYPHEN - U+2018 ('‘'): LEFT SINGLE QUOTATION MARK - U+2019 ('’'): RIGHT SINGLE QUOTATION MARK - U+201c ('“'): LEFT DOUBLE QUOTATION MARK - U+201d ('”'): RIGHT DOUBLE QUOTATION MARK - U+2212 ('−'): MINUS SIGN - U+2217 ('∗'): ASTERISK OPERATOR - U+feff (''): ZERO WIDTH NO-BREAK SPACE (BOM) --- v2: - removed EM/EN DASH conversion from this patchset; - removed a few fixes, as those were addressed on a separate series. PS.: The first version of this series was posted with a different name: https://lore.kernel.org/lkml/cover.1620641727.git.mchehab+huawei@kernel.org/ I also changed the patch texts, in order to better describe the patches goals.

[RFC PATCH] perf cs-etm: Handle valid-but-zero timestamps

by James Clark

There is an intermittent issue on Trogdor devices that results in all Coresight timestamps having a value of zero. Because zero is currently treated as "not found" rather than "found but zero", this breaks the decoding flow when it would otherwise work. This patch adds an out parameter and return code so the difference between zero and non-existent timestamps can be determined. There is also a change to fix an underflow. Although this is a workaround, the change is technically a valid way of writing the cs_etm__etmq_get_timestamp() function. It could have been written similarly to this without trying to work around this issue, so it's no less correct. But, because it's a workaround to a problem elsewhere, I will submit this as an RFC for feedback. This patch applies on top of the "[PATCH v2 0/2] perf cs-etm: Set time on synthesised samples to preserve ordering" patchset.
