Commit52d21580b3"ktest: Use make -s kernelrelease" fixed commit7ff525712a"kbuild: fake the "Entering directory ..." message more simply" as that commit added output after the make kernelrelease. But there's still some build scripts that are used by ktest that has output before the make is executed, and requires that only the last line is printed.

$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

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