From 84fe49d94ac72d7fd226a65d2250c6294885561d Mon Sep 17 00:00:00 2001 From: Roy Hopkins Date: Thu, 3 Jul 2025 16:00:36 +0100 Subject: [PATCH] meson: Add optional dependency on IGVM library MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The IGVM library allows Independent Guest Virtual Machine files to be parsed and processed. IGVM files are used to configure guest memory layout, initial processor state and other configuration pertaining to secure virtual machines. This adds the --enable-igvm configure option, enabled by default, which attempts to locate and link against the IGVM library via pkgconfig and sets CONFIG_IGVM if found. The library is added to the system_ss target in backends/meson.build where the IGVM parsing will be performed by the ConfidentialGuestSupport object. Signed-off-by: Roy Hopkins Acked-by: Michael S.
