From 95dec3e148d6ac27fc19e5a5c2396a3c3cf01633 Mon Sep 17 00:00:00 2001 From: Richard Lyu <richard.lyu@suse.com> Date: Mon, 17 Mar 2025 12:07:48 +0800 Subject: [PATCH] Increase FVMAIN Size for Compatibility with 2MB Size Limit In edk2-stable202502, the increase in code space caused an increase in size, leading to build failures for OVMF under the 2MB size limit due to insufficient space, because FVMAIN_COMPACT had insufficient space. This patch adjusts the memory layout by reducing SEVFV size by 0x10000, as its usage is below 50%, and reallocates the freed 0x10000 space to FVMAIN_COMPACT. This ensures sufficient space to accommodate all code within the FD_SIZE_2MB.
