Hi,
I'm having some trouble using buildman to test the impact of some Kconfig cleanup patches ([1]).
The patches introduce a new CONFIG_SPL_* option and I try to find out which defconfigs need to be fixed, by comparing build sizes.
Now when I added a patch to fix a defconfig I noticed that buildman wouldn't report the expected size changes and upon looking more closely I found that the added Kconfig options are still missing in u-boot-spl.cfg.
The strange thing is, that when I try to build only the last commit then the Kconfig options are there, which is why I suspect a bug in buildman not handling Kconfig changes correctly with consecutive builds.
Can anyone have a look what is wrong or how I can debug this issue?
The issue can be reproduced with the branch at [1], running:
buildman -b spi_flash_kconfig_cleanup_3 --step 0 xilinx_zynqmp_virt
Could you please add "-C" to the buildman command line and have a try?
Indeed forcing the reconfig between the build steps with '-C' fixes the issue.
Is it a known problem, that buildman doesn't handle Kconfig changes correctly without '-C' in some cases?
Thanks, Frieder
for a build where the added Kconfig options are missing in the resulting u-boot-spl.cfg.
And:
buildman -b spi_flash_kconfig_cleanup_3^..spi_flash_kconfig_cleanup_3 xilinx_zynqmp_virt
for a build of only the last commit with expected output.
Thanks, Frieder
