what to do with a private BUILD REGRESSION report ?
by jim.cromie＠gmail.com
I recently (3 hrs ago) got a report from lkp
[jimc:dd-drm-next] BUILD REGRESSION 72004a480e5609bb441794ac5e75fc2aa95ca500
Why is this a private email, and not sent to kbuild-all too ?
It seems counter to convention,
and all my other brown-bag errors are splayed out for ridicule ;-)
and more importantly...
why is it different than the more public reports ?
did this revision get further than previous ones ?
what milestone did it reach ?
As to its contents
Error/Warning in current branch:
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_debug.c:63:54: error: expected ')' before string constant
lib/dynamic_debug.c:1227:52: error: invalid use of undefined type 'struct module'
possible Error/Warning in current branch:
drivers/gpu/drm/drm_print.c:62:52: error: expected ')' before string constant
lib/dynamic_debug.c:1227:52: error: incomplete definition of type 'struct module'
it looks like a proper compile err,
why is it reported this way, and not like others Ive received (this from 8/5)
[kbuild-all] [jimc:dd-drm-next 7/8] drivers/gpu/drm/drm_print.c:64:41: error: expected ')' before string constant
those others include triggering .config, and cross compile script
is the difference that the error is on 8/8, after I shuffled patch order ?
lkp ran the patchset on a lot of configs,
are these configs available for download ?
If they are, could you add a link to the report ?
thanks,
Jim
