[Laurent Navet]

Hi,
maybe a noob's question, but what can we do with these reports ?
How do we know which kernel tree is build, where is the .config ?

How can I have a chance to reproduce and try to fix these errors ?

Regards,

Hi Laurent,

This summary of error messages mainly serves to avoid duplicate
reports/fixing. For example, when someone hit a build error, he may
find this email via google and get to know that it has already been
caught and reported by the 0day kernel build test system.

> How do we know which kernel tree is build, where is the .config ?

Most of the error messages are bisected and directly email reported to
the bad commit's author/committers with the tree/branch/commit/config
information, for example:

tree:   git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git akpm
head:   799385ad830581545b29a54419806af1a9fabb3b
commit: 8a374951fb822d160bfe80b27555e5a6e14c1916 [42/325] sched: /proc/sched_stat fails on very very large machines
config: make ARCH=x86_64 allmodconfig

Another small set of possibly false positive error messages that need
manual checks are reported to kbuild@01.org, which are taken care of
by community volunteers:

        https://lists.01.org/mailman/listinfo/kbuild

That's where you may really help us. :)

> How can I have a chance to reproduce and try to fix these errors ?

The kbuild@01.org email reports will show you the literal commands to
get to the bad commit and code, for example:

git remote add drm-intel git://people.freedesktop.org/~danvet/drm-intel.git
git remote update drm-intel
git checkout 9cc16ce8a74a5aceafa8fa81aac6814b8382b005
vim +6776 drivers/gpu/drm/i915/intel_display.c

Thanks,
Fengguang

Subscribed, let's see what happens,
