From: Mark Brown Date: Mon, 9 Jun 2025 15:25:32 +0000 (+0100) Subject: kselftest/arm64: Fix test for streaming FPSIMD write in sve-ptrace X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=94ab150010f430a36c72e2fe5b7da44a625a6ad5;p=users%2Fjedix%2Flinux-maple.git kselftest/arm64: Fix test for streaming FPSIMD write in sve-ptrace Since f916dd32a943 ("arm64/fpsimd: ptrace: Mandate SVE payload for streaming-mode state") we do not support writing FPSIMD payload data when writing NT_ARM_SSVE but the sve-ptrace test has an explicit test for this being supported which was not updated to reflect the new behaviour. Fix the test to expect a failure when writing FPSIMD data to the streaming mode register set.
