Subject: [PATCH v1 0/2] Handle multi-letter extensions starting with caps in riscv,isa
Date: Wed, 26 Apr 2023 11:43:23 +0100 [thread overview]
Message-ID: <20230426-satin-avenging-086d4e79a8dd@wendy> (raw)
Hey,
Following on from [1] in which Yangyu reported kernel panics for a
riscv,isa string containing "rv64ima_Zifencei", as the parser got
confused by the capital letter, here's a small change to the parser to
handle invalid extensions starting with capital & the removal of some
inaccurate wording from the dt-binding.
Cheers,
Conor.
