From: antohami@basealt.ru To: devel-kernel@lists.altlinux.org Subject: [d-kernel] [PATCH 1/1] config: CONFIG_SQUASHFS_DECOMP_MULTI_PERCPU=y Date: Mon, 13 Mar 2023 14:46:34 +0700 Message-ID: <59c877bbadb1737b2919609e7b97b5a29900ec90.1678693470.git.antohami@altlinux.org> (raw) In-Reply-To: <cover.1678693468.git.antohami@altlinux.org> From: Anton Midyukov <antohami@altlinux.org> 1. Now to enable CONFIG_SQUASHFS_DECOMP_* you need to enable CONFIG_SQUASHFS_COMPILE_DECOMP_*. Since CONFIG_SQUASHFS_COMPILE_DECOMP_MULTI was not set CONFIG_SQUASHFS_DECOMP_MULTI is ignored and CONFIG_SQUASHFS_COMPILE_DECOMP_SINGLE is selected 2. Algorithm MULTI_PERCPU in modern conditions looks better than MULTI. Since hyper_threading is not relevant now, it is not available outside of intel, then there is no point in making two threads per core now. aarch64 processors have many cores, but they are slow.
