Subject: [PATCH v2 05/17] riscv: Fix extension subset checking
Date: Mon, 15 Apr 2024 21:12:02 -0700 [thread overview]
Message-ID: <20240415-dev-charlie-support_thead_vector_6_9-v2-5-c7d68c603268@rivosinc.com> (raw)
In-Reply-To: <20240415-dev-charlie-support_thead_vector_6_9-v2-0-c7d68c603268@rivosinc.com>
This loop is supposed to check if ext->subset_ext_ids[j] is valid, rather
than if ext->subset_ext_ids[i] is valid, before setting the extension
id ext->subset_ext_ids[j] in isainfo->isa.
Signed-off-by: Charlie Jenkins <charlie@rivosinc.com>
Reviewed-by: Conor Dooley <conor.dooley@microchip.com>
Fixes: 0d8295ed975b ("riscv: add ISA extension parsing for scalar crypto")
