From 3e08d9afd273b5dade84fec5f7f17113c47b6b75 Mon Sep 17 00:00:00 2001 From: Gary Lin Date: Fri, 2 Sep 2022 11:26:39 +0800 Subject: [PATCH 1/2] kern/efi/mm: Enlarge the default heap size The default heap size (0x100000, 1MB) is not enough for the openSUSE/SUSE theme, and the additional dynamical allocation of memory regions significantly slows down the loading of the grub2 menu theme. This commit increases the default heap size to 0x2000000, 32MB, and this should be enough to cover the theme files.
