From 6fb6f3096a3c417c8fe1eaaa4e80b230d19ff93d Mon Sep 17 00:00:00 2001 From: Amit Machhiwal Date: Mon, 28 Oct 2024 14:45:36 +0530 Subject: spapr: nested: Add Power11 capability support for Nested PAPR guests in TCG L0 The Power11 architected and raw mode support in Linux was merged via [1] and the corresponding support in QEMU is waiting to be added by [2] which in V6 currently. Add the Power11 capabilities and the required handling in TCG L0 implementation of the "Nested PAPR API". Note: This patch is based on [2].
