Then, I cd into , run 'make modules_install' and get the error above. The issue turns out to be that we when we install firmware pick up the list of firmware blobs from firmware/Makefile. And this triggers the Makefile rules to update ihex2fw. There were two solutions for this issue: 1) Move the list of firmware blobs to a separate file 2) Avoid ihex2fw rebuild by moving it to scripts As I seriously beleive that the list of firmware blobs should be done in a fundamental different way solution 2) was selected.

The reason for that was that too small delays will have their labels mixed up in the graph in an unreadable mess. This patch has a fix for this; for one, it makes the output wider, so more will fit. The second part is that smaller delays are now shown with a much smaller font for the label; while this isn't per se readable at a 1:1 zoom, at least you can zoom in with most SVG viewing applications and see what it is you are looking at.

Instead of using an editor or one of the frontends it's convenient to do this from the command line. It's also useful to do from automated build scripts when building different variants from a base config file. I extracted most of the CONFIG manipulation code from one of my build scripts into a new shell script scripts/config The script is not integrated with the normal Kconfig machinery and doesn't do any checking against Kconfig files, but just manipulates that text format. This is always done at make time anyways. I believe this script would be a useful standard addition for scripts/* Sample usage: ./scripts/config --disable smp Disable SMP in .config file ./scripts/config --file otherdir/.config --module e1000e Enable E1000E as module in otherdir/.config ./scripts/config --state smp y Check state of config option CONFIG_SMP After merging into git please make scripts/config executable Signed-off-by: Andi Kleen Signed-off-by: Sam Ravnborg --- scripts/config | 150 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 150 insertions(+) create mode 100755 scripts/config diff --git a/scripts/config b/scripts/config new file mode 100755 index 000000000000..68b9761cdc38 --- /dev/null +++ b/scripts/config @@ -0,0 +1,150 @@ +#!/bin/bash +# Manipulate options in a .config file from the command line + +usage() { + cat >&2 < Date: Sat, 3 Jan 2009 03:21:42 +0100 Subject: kbuild: add a symlink to the source for separate objdirs I have some scripts which need to map back to the source directory from an objdir.
