How to run well about the Linux Kernel Performance tests
by xly
Hi,
Ying, Fengguang and Tim
I belong to the OS Labs in Tsinghua univ.
I run the lkp-tests on Ubuntu 14.04. and I had a few problems:
1) After I run the command "lkp split-job $LKP_SRC/jobs/hackbench.yaml"， I get the following error message, How should I fix it ?
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- /home/chy/lkp-tests/lib/assert (LoadError)
from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'

from /home/chy/lkp-tests/sbin/split-job:5:in `<main>'
2) After the command "lkp result hackbench" to check result , there are a lot of files in the directory "/result/hackbench/xxx/ubuntu/defconfig/gcc-4.8/3.13.0-24-generic/0/".
and how to analysis these files?
Thanks for Linux Kernel Performance tests Project！

[of/platform] BUG: unable to handle kernel paging request at 6b6b6b7f
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://git.collabora.co.uk/git/user/tomeu/linux.git on-demand-probes-v6
commit 7ec0126d70e7cf5029b717f3b3ecf48ee1d17930
Author: Tomeu Vizoso <tomeu.vizoso(a)collabora.com>
AuthorDate: Tue Aug 11 10:07:10 2015 +0200
Commit: Tomeu Vizoso <tomeu.vizoso(a)collabora.com>
CommitDate: Tue Aug 11 12:09:17 2015 +0200
of/platform: Point to struct device from device node
When adding a platform device, set the device node's device member to
point to it.
This speeds lookups considerably and is safe because we only create one
platform device for any given device node.

Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
commit ef7f0d6a6ca8c9e4b27d78895af86c2fbfaeedb2
Author: Andrey Ryabinin <a.ryabinin(a)samsung.com>
AuthorDate: Fri Feb 13 14:39:25 2015 -0800

x86_64: add KASan support
This patch adds arch specific code for kernel address sanitizer.
16TB of virtual addressed used for shadow memory. It's located in range
[ffffec0000000000 - fffffc0000000000] between vmemmap and %esp fixup
stacks.
At early stage we map whole shadow region with zero page. Latter, after
pages mapped to direct mapping address range we unmap zero pages from
corresponding shadow (see kasan_map_shadow()) and allocate and map a real
shadow memory reusing vmemmap_populate() function.
Also replace __pa with __pa_nodebug before shadow initialized. __pa with
CONFIG_DEBUG_VIRTUAL=y make external function call (__phys_addr)
__phys_addr is instrumented, so __asan_load could be called before shadow
area initialized.
