kern-tools: symbol-why fix and README update

2021-03-11T14:00:36+00:00

There was a bad indent in symbol_why, which we fix with a submitted patch. As part of getting that patch, it was pointed out that there's no README telling people where to send changes. So we add a basic README to avoid that in the future: 8f6aaab docs: add README for patch submission 9f1a6cb symbol_why: fix incorrect indentation of sys.exit(1) (From OE-Core rev: eea536b4368abed2248d3d0c5727a680b7368ce7) Signed-off-by: Bruce Ashfield Signed-off-by: Richard Purdie

kern-tools: non-gcc config support and option re-classification

2020-12-24T08:21:23+00:00

Integrating the following commits: 1aa9046 merge_config.sh: Translate some env variables to make variables 6fdcd64 symbol_why: allow re-classification from non-hardare to hardware With these, a non-gcc compiler can be used, since the invocation of the kernel configuration explicitly passes the variables as command line vars, versus environment variables. This means the kernel Makefile assignments are overriden and the desired compiler used. With option re-classification, we can inhibit warnings when an option has incorrectly been classified has 'hardware', and hence triggers a visible warning.

kernel-yocto: make # is not set matching more precise

2020-08-13T07:07:00+00:00

Integrating the following commit: symbol_why: tighten 'is not set' matching Commented lines that contained CONFIG_FOO ... were being picked up as option lines and reported as invalid. We make the regex more explicit and only match on spaces before CONFIG_ to declare if a 'is not set' line is invalid.

kernel-yocto: enhance configuration queue analysis capabilities

2020-08-08T08:17:49+00:00

Enable the kernel-yocto bbclass to use enhanced capabilities from the kern-tools symbol_why.pl. We bump the kern-tools SRCREV to pickup the reworking of symbol_why, which uses Kconfiglib to provide analysis on configuration values. This is useful for debugging why a symbol specified in a fragment did not end up in the final .config. We introduce two ways to interact with the new symbol_why: 1) a replacement of the existing kconf_check script 2) a dedicated task that is explicitly invoked to dump details on the configuration. The kconf_check replacement is transparent to the user, and is run in exactly the same way as it was previously. But we get better output and more detailed diagnostics if there are symbols that don't make it into the final .config The second way to interact with symbol why is via the new task do_config_analysis. This is invoked like any other task, and by default will provide a full configuration analysis and point the user at files to look at for details. If a more targetted analysis is desired, then specific symbols can be set in the CONFIG_ANALYSIS variable. When this variable is set, the task will only run for the given symbols and provide per-variable links to the user. This variable can be set like any other, including specification in the local.conf: CONFIG_ANALYSIS_pn-linux-yocto-dev = 'NF_CONNTRACK LOCALVERSION' Which produces output as follows: WARNING: linux-yocto-dev-5.8-rc++gitAUTOINC+d22beb8f8a_8fc484ed37-r0 do_config_analysis: Configuration analysis executed, see: tmp/work/qemuarm64-poky-linux/linux-yocto-dev/5.8-rc++gitAUTOINC+d22beb8f8a_8fc484ed37-r0/NF_CONNTRACK-config-analysis.txt for details WARNING: linux-yocto-dev-5.8-rc++gitAUTOINC+d22beb8f8a_8fc484ed37-r0 do_config_analysis: Configuration audit executed, see: tmp/work/qemuarm64-poky-linux/linux-yocto-dev/5.8-rc++gitAUTOINC+d22beb8f8a_8fc484ed37-r0/NF_CONNTRACK-config-audit.txt for details WARNING: linux-yocto-dev-5.8-rc++gitAUTOINC+d22beb8f8a_8fc484ed37-r0 do_config_analysis: Configuration analysis executed, see: tmp/work/qemuarm64-poky-linux/linux-yocto-dev/5.8-rc++gitAUTOINC+d22beb8f8a_8fc484ed37-r0/LOCALVERSION-config-analysis.txt for details WARNING: linux-yocto-dev-5.8-rc++gitAUTOINC+d22beb8f8a_8fc484ed37-r0 do_config_analysis: Configuration audit executed, see: work/qemuarm64-poky-linux/linux-yocto-dev/5.8-rc++gitAUTOINC+d22beb8f8a_8fc484ed37-r0/LOCALVERSION-config-audit.txt for details (From OE-Core rev: cbc896def4c8bab3150d3405969e5dd018d62d0c) Signed-off-by: Bruce Ashfield Signed-off-by: Richard Purdie

kern-tools: fix merge_config when LD contains parameters

2020-02-08T13:20:02+00:00

To ensure that the kernel linker is used when allno/mod/yes config merge_config steps were executed, the call to make was tweaked to explicitly pass LD. But since the variable wasn't quoted, any parameters to LD (like the sysroot) were mistakenly passed to make, and hence could trigger an error on some architectures. We also tweak the logging to hightlight errors like this in the future and avoid losing it in the noise of merge configs sometimes overly verbose output.

kern-tools: update Kconfiglib to latest (for 5.4+ kernel)

2020-02-03T00:10:11+00:00

When a symbol doesn't make it into the final analysis is run using Kconfiglib to show dependencies. v5.4 has introduced Kconfig elements that Kconfiglib can't parse (hence we get no analysis). Updating the Kconfiglib snapshot solves our problem. (From OE-Core rev: 240e0ae13d35469eecafc82d2cd9cfd110095c55) Signed-off-by: Bruce Ashfield Signed-off-by: Richard Purdie
