From cd53ee9c41f991bbca75641e647005e013a3eac0 Mon Sep 17 00:00:00 2001 From: Michal Orzel Date: Thu, 29 Feb 2024 13:13:52 +0100 Subject: [PATCH] SUPPORT.md: clarify support of booting 32-bit Xen on ARMv8 Since commit bd1001db0af1 ("xen/arm: arm32: Allow Xen to boot on unidentified CPUs"), it's been possible to boot 32-bit Xen on ARMv8A CPUs in AArch32 state (assuming HW supports EL2 execution in AArch32). Clarify the support statement and mark it as Tech Preview, as this use case is uncommon and hasn't really been tested/hardened.
