Subject: [PATCH v4 0/8] perf: Arm SPEv1.2 support
Date: Mon, 09 Jan 2023 13:26:17 -0600 [thread overview]
Message-ID: <20220825-arm-spe-v8-7-v4-0-327f860daf28@kernel.org> (raw)
Peter, this series is blocked on an ack from you on patch 7. There was
some discussion on validation of the 'config3' attr. The options where
laid out by Mark here[0]. Please chime in on your preference.
Will, can you pick up patches 1-6 at least if there's no progress on
'config3'.
This series adds support for Arm SPEv1.2 which is part of the
Armv8.7/Armv9.2 architecture. There's 2 new features that affect the
kernel: a new event filter bit, branch 'not taken', and an inverted
event filter register.
Since this support adds new registers and fields, first the SPE register
defines are converted to automatic generation.
The perf tool side changes are available here[1].
Tested on FVP.
