scripts: Switch to more portable Perl shebang

2017-05-14T02:20:44+00:00

The default NetBSD package manager is pkgsrc and it installs Perl along other third party programs under custom and configurable prefix. The default prefix for binary prebuilt packages is /usr/pkg, and the Perl executable lands in /usr/pkg/bin/perl. This change switches "/usr/bin/perl" to "/usr/bin/env perl" as it's the most portable solution that should work for almost everybody. Perl's executable is detected automatically. This change switches -w option passed to the executable with more modern "use warnings;" approach. There is no functional change to the default behavior. While there, drop "require 5" from scripts/namespace.pl (Perl from 1994?). Signed-off-by: Kamil Rytarowski Signed-off-by: Masahiro Yamada

kbuild: Make scripts executable

2014-08-20T14:03:45+00:00

The Makefiles call the respective interpreter explicitly, but this makes it easier to use the scripts manually. Signed-off-by: Michal Marek

scripts/bootgraph.pl: Add graphic header

Adding -header + help function like other .pl in /scripts. Signed-off-by: Fabian Frederick Signed-off-by: Michal Marek

bootgraph.pl: relax timing information requirements

2011-06-12T22:04:57+00:00

This patch removes the assumption of the bootgraph.pl script that the timing information reported by PRINTK_TIME will contain at least one entry with a time of less than 100 seconds. Not all boards correctly reset the system timer and in many cases the inital times reported by PRINTK_TIME is high. When this occurs the bootchart.pl script fails to give any useful output. This patch sets the $firsttime variable to the largest value expected by PRINTK_TIME Signed-off-by: Andrew Murray Acked-by: Arjan van de Ven Signed-off-by: Jiri Kosina

bootgraph: fix for use with dot symbols

2009-02-15T11:50:08+00:00

powerpc has dot symbols, so the dmesg output looks like: <4>[ 0.327310] calling .migration_init+0x0/0x9c @ 1 <4>[ 0.327595] initcall .migration_init+0x0/0x9c returned 1 after 0 usecs The below fixes bootgraph.pl so it handles this correctly.

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

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.

tracing/fastboot: put error message on stderr
