From: Zeyu Dong Date: Sat, 30 Sep 2023 00:54:58 +0000 (-0400) Subject: build: cache kernel module package compiling X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=52751b12320599b557d8c7779b612102b963595d;p=openwrt%2Fstaging%2Fstintel.git build: cache kernel module package compiling Kernel module packages compiling is not cached (e.g. mac80211) even with CONFIG_CCACHE on. CC should be set to KERNEL_CC in KERNEL_MAKE_FLAGS at kernel.mk to allow kernel module packages using ccache.
