From d83d350cb2f9edbdb4eccc6454c82202a09483c8 Mon Sep 17 00:00:00 2001 From: Benjamin Gray Date: Wed, 27 Dec 2023 23:46:50 +1000 Subject: [PATCH] ppc/spapr: Add pa-features for POWER10 machines Add POWER10 pa-features entry. Notably DEXCR and [P]HASHST/[P]HASHCHK instruction support is advertised. Each DEXCR aspect is allocated a bit in the device tree, using the 68--71 byte range (inclusive). The functionality of the [P]HASHST/[P]HASHCHK instructions is separately declared in byte 72, bit 0 (BE).
