lz4c has been considered deprecated by upstream since at least 2018 [1] and has been disabled by default recently [2]. openSUSE Tumbleweed is no longer packaging the deprecated version and others will likely follow. Going back as far as Ubuntu 16.04/Fedora 25, both lz4 and lz4c are installed as part of the same package and both accept -9 to enable high compression so switching should be safe. 1. https://github.com/lz4/lz4/pull/553 2. https://github.com/lz4/lz4/pull/1479 Signed-off-by: Justin Bronder <jsbronder@xxxxxxxxxxxxxx> --- Makefile | 2 +- scripts/Makefile.lib | 4 ++-- 2 files changed, 3 insertions(+), 3 deletions(-) diff --git a/Makefile b/Makefile index 68a8faff2543..ded07aca0d2a 100644 --- a/Makefile +++ b/Makefile @@ -508,7 +508,7 @@ KGZIP = gzip KBZIP2 = bzip2 KLZOP = lzop LZMA = lzma -LZ4 = lz4c +LZ4 = lz4 XZ = xz ZSTD = zstd diff --git a/scripts/Makefile.lib b/scripts/Makefile.lib index 01a9f567d5af..b73950bfee34 100644 --- a/scripts/Makefile.lib +++ b/scripts/Makefile.lib @@ -371,10 +371,10 @@ quiet_cmd_lzo_with_size = LZO $@ cmd_lzo_with_size = { cat $(real-prereqs) | $(KLZOP) -9; $(size_append); } > $@ quiet_cmd_lz4 = LZ4 $@ - cmd_lz4 = cat $(real-prereqs) | $(LZ4) -l -c1 stdin stdout > $@ + cmd_lz4 = cat $(real-prereqs) | $(LZ4) -l -9 stdin stdout > $@ quiet_cmd_lz4_with_size = LZ4 $@ - cmd_lz4_with_size = { cat $(real-prereqs) | $(LZ4) -l -c1 stdin stdout; \ + cmd_lz4_with_size = { cat $(real-prereqs) | $(LZ4) -l -9 stdin stdout; \ $(size_append); } > $@ # U-Boot mkimage -- 2.47.0
