Subject: [PATCH v1 0/3] arm64: Boot requirements clarifications
Date: Mon, 12 Apr 2021 16:19:52 +0100 [thread overview]
Message-ID: <20210412151955.16078-1-broonie@kernel.org> (raw)
This series makes explicit our booting requirements in a number of
areas, mainly the initialisation of optional floating point features.
While no issues have been encountered it seems better to be explict,
particularly given that new extensions frequently require setup from
higher exception levels to be functional so our list of explicit
requirement is tending to become more and more exhaustive creating some
expecation that requirements will be stated clearly.
Due to a collision with my recent FGT series this series is based on top
of arm64/for-next/fgt-boot-init.
Mark Brown (3):
arm64: Relax booting requirements for configuration of traps
arm64: Explicitly require that FPSIMD instructions do not trap
arm64: Explicitly document boot requirements for SVE
