Previous ID: LIN7-5762
Found In Version: 6.0.0.27
Fix Version: 6.0.0.29
Severity: Standard
Applicable for: Wind River Linux 6
Component/s: Kernel
Host OS: Linux Ubuntu
Architecture: All
This defect affects WRL6, and WRL7 and probably on WRL8 too
The kconf_check tool fails to find certains valid kernel options.
It contains this part:
---
for i in `cat $KCONF_DIR/all.kcf` ; do
cat $LINUX_SRC/$i | grep '^[ ]*\(menu\)*config ' | \
awk '{print "CONFIG_"$2}' >> $KCONF_DIR/all.cfg done
---
I.e. it assumes a config keyword is followed by a space. That is not always true.
Many Kconfig files contain a tab character after the config keyword.
That causes the kconf_check script to fail to find a number of config options and if any of those options are in the users "config-input", will cause the option to be mistakenly reported in the "invalid.cfg" file.
* Makefile:
Simple makefile to show how I run configure.
* meta-foo
A simple layer with an addition kernel configuration.
It adds:
CONFIG_DAVINCI_CLKINIT=y
* out_save
I saved the files mentioned below from my build.
* How to run
$ make configure
$ make bbs
$ bitbake -f -c compile linux-windriver
* Files to check:
- out/build/build/linux-windriver/temp/do_kernel_configcheck/log.do_kernel_configcheck.*
Will have an entry with:
[invalid (1)]: .meta/cfg/standard/lsi-axm55xx/invalid.cfg
This BSP sets config options that are not offered anywhere within this kernel
- out/build/build/linux-windriver/linux/.meta/cfg/standard/lsi-axm55xx/all.cfg
This file should contain all valid config options in the kernel source.
Due to this bug it will miss those with "config<tab>".
(E.g. it does not have an entry for CONFIG_DAVINCI_CLKINIT)
- out/build/build/linux-windriver/linux/.meta/cfg/standard/lsi-axm55xx/invalid.cfg
Will have an entry for CONFIG_DAVINCI_CLKINIT. (Due to all.cfg not having it.)
