LSB Result

Introduction

The Linux Standard Base(LSB) was created to lower the overall costs of supporting the Linux platform. By reducing the differences between individual Linux distributions, the LSB greatly reduces the costs involved with porting applications to different distributions, as well as lowers the cost and effort involved in after-market support of those applications. (http://www.linuxfoundation.org/collaborate/workgroups/lsb)

LSB Test Suite support the following architecture.

• i486
• ia64
• ppc32
• ppc64
• s390
• s390x
• x86_64

LSB doesn't support arm and mips at present and maybe support in the future. YOCTO will make lsb test before releasing a new version.

Fixing bugs reported by LSB Test Suite has completed on Mar 5th 2012. All of bugs have been fixed at that point. But some new bugs arise during lsb test recently because of the updating for OE-Core since Mar 5th 2012. These new bugs will be fixed in 1.3.

Test Environment

• Image: core-image-lsb-qt3
• Platform: x86-32(emenlow), x86-64(jasperforest), ppc(mpc8315e-rdb)
• Version of LSB Test Suite: 4.1

Setup test environment

We setup LSB test environment on emenlow as an example.

• Build the image

1. Download the poky source

$ git clone git://git.pokylinux.org/poky.git

2. Download the intel BSP meta source

$ cd poky
$ git clone git://git.pokylinux.org/meta-intel.git

3. Downloand the qt3 meta source

$ git clone git://git.pokylinux.org/meta-qt3.git

4. Prepare the build environment

$ source oe-init-build-env

5. Edit the conf/bblayers.conf and conf/local.conf(LSB 4.1 core test requires pam support, so open the distro feature “pam”）

$ vi conf/bblayers.conf

…...
BBLAYERS = " \ 
  ##COREBASE##/meta \ 
  ##COREBASE##/meta-yocto \ 
  ##COREBASE##/meta-intel \
  ##COREBASE##/meta-intel/meta-emenlow \ 
  ##COREBASE##/meta-qt3 \
“

$ vi conf/local.conf

…...
MACHINE ?= "emenlow"
…... 
DISTRO ?= "poky-lsb 
DISTRO_FEATURES_append += " pam"
…...

6. Build

$ bitbake core-image-lsb-qt3

When build successfully, you can find the kernel, rootfs image, rootfs cpio tarball, and modules tarball in build/tmp/deploy/images direcotry.

• Install system

We assume that there is already a default OS on target(You can install the system by following the README.hardware in poky source). In order to install the new system, you need to prepare a free disk partition. If not, you need to create it by running 'fdisk' command. We assume the free disk partition is /dev/sda5.

There are 2 ways to install the rootfs to the target: Using rootfs image or using rootfs cpio tarball.

Using rootfs image:

1. Boot up the emenlow hardware by default mode.

2. Copy core-image-lsb-qt3-emenlow.ext3 to emenlow from host:

$ scp core-image-lsb-qt3-emenlow.ext3 root@emenlow-ip:/

3. Install the core-image-lsb-qt3-emenlow.ext3 to a free disk partition.

emenlow$ mount /dev/sda5 /mnt 
emenlow$ dd if=core-image-lsb-qt3-emenlow.ext3 of=/dev/sda5 
emenlow$ umount /mnt 
emenlow$ e2fsck -f /dev/sda5 
emenlow$ resize2fs /dev/sda5 

Using rootfs cpio tarball:

1. Boot up the emenlow hardware by default mode.

2. Copy core-image-lsb-qt3-emenlow.cpio.gz to emenlow from host:

$ scp core-image-lsb-qt3-emenlow.cpio.gz root@emenlow-ip:/

3. Install the core-image-lsb-qt3-emenlow.cpio.gz to a free disk partition.

emenlow$ gzip -d core-image-lsb-qt3-emenlow.cpio.gz
emenlow$ mount /dev/sda5 /mnt 
emenlow$ cd /mnt; cpio -ivdm <../core-image-lsb-qt3-emenlow.cpio 
emenlow$ sync; umount /mnt  

Then install the kernel and modified the grub.

1. Copy kernel to emenlow from host. We assume your boot disk partition is /dev/sda1:

$ scp bzImage-emenlow.bin root@emenlow-ip:/
$ mount /dev/sda1 /mnt
$ cp bzImage-emenlow.bin /mnt/boot/bzImage

2. Modify grub menu.lst

$ vi /mnt/boot/grub/menu.lst

add new lines as below:

title LSB 
root  (hd0,0) 
kernel /boot/bzImage root=/dev/sda5 rw

You can also change the default boot sequence.

3. Restart the emenlow

• Install LSB testsuite

You can follow the File:LSB Test.pdf to install and run LSB test.

Analysis of result

Below table shows the failed test cases.

• Total failures: The number of total failures after running test. It includes known problems and real failures which should be fixed.
• Known problem: Known problem means it is a bug of LSB itself and we can find trace these bugs on http://bugs.linuxbase.org. On link page we give a summary of known problems.
• Failures(need to fix) : Real failures we should fix them
• Test suite error : Caused by two reasons: one is for absent library needed by test suite. one is that test suite could lose some function which should be included in it.

x86 (emenlow,update(2013-03-12))

• New problem: It is a bug without arising on previous version. It could be caused by some patches updated every day.

ppc(mpc8315e,update (2012-04-13))

We have the following failures(including "unresolved" and "failed") to fix.

Core Tests	67	67

• For new problem, it has others besides the problems emenlow has
  • Qt4-Azov Tests
    • "Child process timed out" caused many unresolved items
  • No locale and charmap in the latest lsb image, there were many failures because of the absent of locale resources.
• Illegal instruction(Known problem http://bugs.linuxbase.org/show_bug.cgi?id=3253)
  • 65 SIGILL error
    • Core Tests
      • /tset/ANSI.os/math/... : SIGILL cause 47 unresolved failures.
      • /tset/LSB.os/libm/fpeInvalid/T.fpeInvalid (1st--2nd)
    • Desktop-t2c Tests
      • /glib-t2c/tests/glib_random/glib_random (9th--23rd)
    • Xpdf Tests
      • pdftotext
  • It was caused by the difference of compilation tool between LSB Test Suite and mpc8315e. In fact, instruction "fsqrt" doesn't exist on e300core serial and CPU of mpc8315e belongs to e300core type. So this problem can't be solved for mpc8315e
• OLVER Core Tests:
  • OLVER Core Tests can't be finished on mpc8315e-rdb
  • We think the reason which make test blocked is the low memory(128M on mpc8315e). Because we re-run the test case which is blocked during OLVER core tests and it can pass successfully. That is to say, if we run the single test case, it will be passed. But we run all OLVER core tests and the whole tests will be blocked. We have ever run OLVER Core Tests for nearly 50 hours and it can't finish.
  • lsb-test-olver-core may require about 512Mb of system memory (with an X server and a contemporary desktop running), as well as 2Gb of free disk space to complete a test run. The reference linkage: http://ldn.linuxfoundation.org/lsb/preparing-lsb-distribution-testing
• Qt3-Azov Tests, Printing Tests
  • Out of memory error cause all of the failures, the information like the following arise on screen when running Qt3 and Printing test suite

We should fix the following problems. We also filed bugs for them and try to fix them.
