bootgraph: make the bootgraph script show async waiting time

2009-01-10T23:06:52+00:00

It is useful for diagnosing boot performance to see where async function calls are waiting on serialization... this patch adds this functionality to the bootgraph.pl script. The waiting time is shown as a half transparent, gray bar through the block that is waiting. Signed-off-by: Arjan van de Ven Signed-off-by: Linus Torvalds

kconfig: add script to manipulate .config files on the command line

2009-01-07T20:44:22+00:00

I often change single options in .config files. 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

kbuild: reintroduce ALLSOURCE_ARCHS support for tags/cscope

2009-01-07T20:44:21+00:00

This patch reintroduce the ALLSOURCE_ARCHS support for tags/TAGS/ cscope targets. The Kbuild previously has this feature, but after moving the targets into scripts/tags.sh, ALLSOURCE_ARCHS disappears. It's something like this: $ make ALLSOURCE_ARCHS="x86 mips arm" tags cscope Signed-off-by: Jike Song Signed-off-by: Sam Ravnborg

bootchart: improve output based on Dave Jones' feedback

2009-01-07T20:44:21+00:00

Dave Jones, in his blog, had some feedback about the bootchart script: Primarily his complaint was that shorter delays weren't visualized. 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.

fix modules_install via NFS

2009-01-07T20:44:20+00:00

Rafael reported: I get the following error from 'make modules_install' on my test boxes: HOSTCC firmware/ihex2fw /home/rafael/src/linux-2.6/firmware/ihex2fw.c:268: fatal error: opening dependency file firmware/.ihex2fw.d: Read-only file system compilation terminated. make[3]: *** [firmware/ihex2fw] Error 1 make[2]: *** [_modinst_post] Error 2 make[1]: *** [sub-make] Error 2 make: *** [all] Error 2 where the configuration is that the kernel is compiled on a build box with 'make O= -j5' and then is mounted over NFS read-only by each test box (full path to this directory is the same on the build box and on the test boxes). 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.

checkpatch: struct file_operations should normally be const

2009-01-06T23:59:17+00:00

In the general use case struct file_operations should be a const object. Check for and warn where it is not. As suggested by Steven and Ingo. Acked-by: Steven Rostedt Cc: Ingo Molnar Signed-off-by: Andy Whitcroft Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

checkpatch: ensure we actually detect if assignments split across lines

2009-01-06T23:59:17+00:00

When checking for assignments within if conditionals we check the whole of the condition, but the match is performed using a line constrained regular expression. This means we can miss split conditionals or those on the second line. Allow the check to span lines. Signed-off-by: Andy Whitcroft Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

checkpatch: do not report nr_static as a static declaration

2009-01-06T23:59:17+00:00

Ensure we do not report identifiers containing the word static as static declarations. For example this should not be reported as an unecessary assignement of 0: long nr_static = 0; Signed-off-by: Andy Whitcroft Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
