in my local tree for some time. I need to push them upstream:
- Separate out config-bisect.pl from ktest.pl.
This allows users to do config bisects without full ktest setup.
- Email on status change.
Allow the user to be emailed on test start, finish, failure, etc.
- Other small fixes and enhancements

CONSOLE = nc -d localhost 3001

Required version ending to differentiate the test

EOF

|
|
$config_help{"REBOOT_TYPE"} = << "EOF"
|
|
Way to reboot the box to the test kernel.
|
|
Only valid options so far are "grub", "grub2", "syslinux", and "script".
|
|
|
|
If you specify grub, it will assume grub version 1
|
|
and will search in /boot/grub/menu.lst for the title \$GRUB_MENU
|
|
and select that target to reboot to the kernel. If this is not
|
|
your setup, then specify "script" and have a command or script
|
|
specified in REBOOT_SCRIPT to boot to the target.
|
|
|
|
The entry in /boot/grub/menu.lst must be entered in manually.
|
|
The test will not modify that file.
|
|
|
|
If you specify grub2, then you also need to specify both \$GRUB_MENU
|
|
and \$GRUB_FILE.
|
|
|
|
If you specify syslinux, then you may use SYSLINUX to define the syslinux
|
|
command (defaults to extlinux), and SYSLINUX_PATH to specify the path to
|
|
the syslinux install (defaults to /boot/extlinux). But you have to specify
|
|
SYSLINUX_LABEL to define the label to boot to for the test kernel.
|
|
EOF
|
|
;
|
|
$config_help{"GRUB_MENU"} = << "EOF"
|
|
The grub title name for the test kernel to boot
|
|
(Only mandatory if REBOOT_TYPE = grub or grub2)
|
|
|
|
Note, ktest.pl will not update the grub menu.lst, you need to
|
|
manually add an option for the test. ktest.pl will search
|
|
the grub menu.lst for this option to find what kernel to
|
|
reboot into.
|
|
|
|
For example, if in the /boot/grub/menu.lst the test kernel title has:
|
|
title Test Kernel
|
|
kernel vmlinuz-test
|
|
GRUB_MENU = Test Kernel
|
|
|
|
For grub2, a search of \$GRUB_FILE is performed for the lines
|
|
that begin with "menuentry". It will not detect submenus. The
|
|
menu must be a non-nested menu. Add the quotes used in the menu
|
|
to guarantee your selection, as the first menuentry with the content
|
|
of \$GRUB_MENU that is found will be used.
|

EOF

$config_help{"GRUB_FILE"} = << "EOF"

If grub2 is used, the full path for the grub.cfg file is placed

here. Use something like /boot/grub2/grub.cfg to search.

EOF

$config_help{"SYSLINUX_LABEL"} = << "EOF"

If syslinux is used, the label that boots the target kernel must

be specified with SYSLINUX_LABEL.
