Subject: [PATCH 0/6] perf cs-etm: Support TRBE (unformatted decoding)
Date: Tue, 13 Jul 2021 16:40:02 +0100 [thread overview]
Message-ID: <20210713154008.29656-1-james.clark@arm.com> (raw)
This patchset consists of refactoring to allow the decoder to be
created in advance when the AUX records are iterated over. The
AUX record flags are used to communicate whether the data is
formatted or not which is the reason this refactoring is required.
These changes result in some simplifications, removal of early exit
conditions etc.
A change was also made to --dump-raw-trace code to allow the
formatted/unformatted status to persist and for the decoder to
not be continually deleted and recreated.
The changes apply on top of the previous patchset "[PATCH v7 0/2] perf
cs-etm: Split Coresight decode by aux records".
James Clark (6):
perf cs-etm: Refactor initialisation of kernel start address
perf cs-etm: Split setup and timestamp search functions
perf cs-etm: Only setup queues when they are modified
perf cs-etm: Suppress printing when resetting decoder
perf cs-etm: Use existing decoder instead of resetting it
perf cs-etm: Pass unformatted flag to decoder
