[PULL 06/10] target/ppc: Use SMT4 small core chip type in POWER9/10 PVRs
Posted by Daniel Henrique Barboza 2 years, 6 months ago
From: Nicholas Piggin <npiggin@gmail.com>

QEMU's PVR value for POWER9 DD2.0 has chip type 1, which is the SMT4
"small core" type that OpenPOWER processors use. QEMU's PVR for all
other POWER9/10 have chip type 0, which "enterprise" systems use.

The difference does not really matter to QEMU (because it does not care
about SMT mode in the target), but for consistency all PVRs should use
the same chip type. We'll go with the SMT4 OpenPOWER type.
