From 25dd7a2f56e8e44258be4df6daa22ca354c9da88 Mon Sep 17 00:00:00 2001 From: Dmitry Selyutin Date: Tue, 3 May 2022 16:40:29 +0000 Subject: [PATCH] ppc/svp64: support LibreSOC architecture This patch adds support for LibreSOC machine and SVP64 extension flag for PowerPC architecture. SV (Simple-V) is a strict RISC-paradigm Scalable Vector Extension for the Power ISA. SVP64 is the 64-bit Prefixed instruction format implementing SV. Funded by NLnet through EU Grants No: 825310 and 825322, SV is in DRAFT form and is to be publicly submitted via the OpenPOWER Foundation ISA Working Group via the newly-created External RFC Process.
