From e505e6bf4205255bf6e0daba9ea0f80b6391b936 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 24 Feb 2023 14:52:30 +0100 Subject: [PATCH] arm64: defconfig: Add IOSCHED_BFQ to the default configs ARM64 systems are often memory constrained and more often than not use slow single-channel storage such as flash memory or MMC/SD-cards. For any interactive systems (such as mobile phones, tablets, chromebooks...) the BFQ I/O scheduler will be desireable. Make sure the BFQ I/O scheduler is available on these systems. ARM (32), Loongarch, MIPS, m68k, UM and S390 has also enabled BFQ in their defconfigs, cf commit b495dfed706c4c5873c0dab8930ad6eb1d276a6c "um: Cleanup CONFIG_IOSCHED_CFQ" where the motivation is that it replaces the former CFQ scheduler.
