From ed149717eec3bfe42d4cc32ee1d74cc53a19bad5 Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Fri, 5 Apr 2024 14:29:50 +0200 Subject: [PATCH] tools: zstd: override max safe compression level ZTSD limits the safe compression level to a max of 19 as 20 to 22 cause increased RAM usage. Higher levels require --ultra arg passed. There isn't currently a way to set --ultra using ENV options similar to ZSTD_CLEVEL and ZSTD_CLEVEL is limited to 19. To fix this, we can increase the max safe compression level by providing a custom ZSTDCLI_CLEVEL_MAX value with CFLAGS. The max safe level is increased to 20.
