From f00373b895da830ef6d0ee9a518e336e8252a4a3 Mon Sep 17 00:00:00 2001 From: Rowan Hart Date: Fri, 27 Jun 2025 12:25:04 +0100 Subject: plugins: Add memory virtual address write API MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch adds functions to the plugins API to allow reading and writing memory via virtual addresses. These functions only permit doing so on the current CPU, because there is no way to ensure consistency if plugins are allowed to read or write to other CPUs that aren't currently in the context of the plugin.
