From c47c7ab9b53635860c6b48736efdd22822d726d7 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Tue, 8 Feb 2022 12:17:26 -0700 Subject: [PATCH] MIPS: Malta: Enable BLK_DEV_INITRD This configuration is useful for boot testing malta_defconfig in QEMU with just a simple cpio initrd, instead of a full ext4 rootfs. This results in an increase of ~164KB of vmlinux (with GCC 11.2.0): $ diskus vmlinux.before 11.19 MB (11,194,368 bytes) $ diskus vmlinux.after 11.36 MB (11,358,208 bytes) This size increase comes from the fact that usr/Kconfig is sourced when CONFIG_BLK_DEV_INITRD is enabled, which defaults to supporting several decompression algorithms for compressed initrds. This seems like a reasonable tradeoff but these configurations could be disabled in the future if there are complaints about the size increase.
