Subject: [PULL 05/38] target/ppc: POWER10 does not have transactional memory
Date: Wed, 13 Mar 2024 02:58:16 +1000 [thread overview]
Message-ID: <20240312165851.2240242-6-npiggin@gmail.com> (raw)
In-Reply-To: <20240312165851.2240242-1-npiggin@gmail.com>
POWER10 hardware implements a degenerate transactional memory facility
in POWER8/9 PCR compatibility modes to permit migration from older
CPUs, but POWER10 / ISA v3.1 mode does not support it so the CPU model
should not support it.
