Message-Id: <20241107-arm64-fp-stress-irritator-v2-3-c4b9622e36ee@kernel.org> Date: Thu, 07 Nov 2024 01:39:22 +0000 From: Mark Brown <broonie@...nel.org> To: Catalin Marinas <catalin.marinas@....com>, Will Deacon <will@...nel.org>, Shuah Khan <shuah@...nel.org> Cc: Mark Rutland <mark.rutland@....com>, linux-arm-kernel@...ts.infradead.org, linux-kselftest@...r.kernel.org, linux-kernel@...r.kernel.org, Mark Brown <broonie@...nel.org> Subject: [PATCH v2 3/6] kselftest/arm64: Corrupt P0 in the irritator when testing SSVE When building for streaming SVE the irritator for SVE skips updates of both P0 and FFR. While FFR is skipped since it might not be present there is no reason to skip corrupting P0 so switch to an instruction valid in streaming mode and move the ifdef.
