From 5dffbe811b78684fc4d8538cb7b38d9c47f96f9f Mon Sep 17 00:00:00 2001 From: Segher Boessenkool Date: Sun, 6 Apr 2008 22:16:07 +0200 Subject: [PATCH] kbuild: show defconfig subdirs in make help PowerPC will start moving board defconfigs into subarch-specific subdirs soon. "make help" currently does not look in subdirs to find the defconfigs to show. This is partially a good thing, since there are way too many defconfigs for one list. This patch makes the main "make help" display something like help-40x - Show 40x-specific targets help-44x - Show 44x-specific targets help-boards - Show all of the above and wires up stuff so those new help-* commands actually work. [sam: fixed it up to display x86 defconfigs too] Cc: Josh Boyer Signed-off-by: Segher Boessenkool Signed-off-by: Sam Ravnborg --- Makefile | 23 ++++++++++++++++++++++- 1 file changed, 22 insertions(+), 1 deletion(-) diff --git a/Makefile b/Makefile index fc3411e..da76f51 100644 --- a/Makefile +++ b/Makefile @@ -1174,8 +1174,10 @@ rpm: include/config/kernel.release FORCE # Brief documentation of the typical targets used # --------------------------------------------------------------------------- -boards := $(wildcard $(srctree)/arch/$(ARCH)/configs/*_defconfig) +boards := $(wildcard $(srctree)/arch/$(SRCARCH)/configs/*_defconfig) boards := $(notdir $(boards)) +board-dirs := $(dir $(wildcard $(srctree)/arch/$(SRCARCH)/configs/*/*_defconfig)) +board-dirs := $(sort $(notdir $(board-dirs:/=))) help: @echo 'Cleaning targets:' @@ -1229,6 +1231,11 @@ help: $(foreach b, $(boards), \ printf " %-24s - Build for %s\\n" $(b) $(subst _defconfig,,$(b));) \ echo '') + @$(if $(board-dirs), \ + $(foreach b, $(board-dirs), \ + printf " %-16s - Show %s-specific targets\\n" help-$(b) $(b);) \ + printf " %-16s - Show all of the above\\n" help-boards; \ + echo '') @echo ' make V=0|1 [targets] 0 => quiet build (default), 1 => verbose build' @echo ' make V=2 [targets] 2 => give reason for rebuild of target' @@ -1240,6 +1247,20 @@ help: @echo 'For further info see the ./README file' +help-board-dirs := $(addprefix help-,$(board-dirs)) + +help-boards: $(help-board-dirs) + +boards-per-dir = $(notdir $(wildcard $(srctree)/arch/$(SRCARCH)/configs/$*/*_defconfig)) + +$(help-board-dirs): help-%: + @echo 'Architecture specific targets ($(SRCARCH) $*):' + @$(if $(boards-per-dir), \ + $(foreach b, $(boards-per-dir), \ + printf " %-24s - Build for %s\\n" $*/$(b) $(subst _defconfig,,$(b));) \ + echo '') + + # Documentation targets # --------------------------------------------------------------------------- %docs: scripts_basic FORCE -- 2.7.4
