Something like this takes the time for 'headers_install_all' from 30s to 20s on my machine, and from 9s to 1.5s when it doesn't actually have to do anything. I have yet to actually remove $(BIARCH) and just override $(dst), though. diff --git a/Makefile b/Makefile index eff8fee..4eae126 100644 --- a/Makefile +++ b/Makefile @@ -1017,6 +1017,14 @@ headers_install_all: __headers BIASMDIR=-bi-$$arch ;\ done +PHONY += headers_install_all_faster +headers_install_all_faster: __headers + $(Q)$(MAKE) ARCH= SRCARCH= $(hdr-inst)=include + $(Q)set -e; for arch in $(hdr-archs); do \ + $(MAKE) ARCH=$$arch SRCARCH=$$arch $(hdr-inst)=include/asm-$$arch \ + BIASMDIR=-bi-$$arch ;\ + done + PHONY += headers_install headers_install: __headers $(Q)if [ ! -r $(srctree)/include/asm-$(SRCARCH)/Kbuild ]; then \ diff --git a/include/Kbuild b/include/Kbuild index b522887..9393f7e 100644 --- a/include/Kbuild +++ b/include/Kbuild @@ -5,4 +5,6 @@ header-y += mtd/ header-y += rdma/ header-y += video/ +ifneq ($(ARCH),) header-y += asm-$(ARCH)/ +endif -- dwmw2 -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
