114 | $config_help{"MACHINE"} = << "EOF" | |
115 | The machine hostname that you will test. | |
116 | EOF | |
117 | ; | |
118 | $config_help{"SSH_USER"} = << "EOF" | |
119 | The box is expected to have ssh on normal bootup, provide the user | |
120 | (most likely root, since you need privileged operations) | |
121 | EOF | |
122 | ; | |
123 | $config_help{"BUILD_DIR"} = << "EOF" | |
124 | The directory that contains the Linux source code (full path). | |
125 | EOF | |
126 | ; | |
127 | $config_help{"OUTPUT_DIR"} = << "EOF" | |
128 | The directory that the objects will be built (full path). | |
129 | (can not be same as BUILD_DIR) | |
130 | EOF | |
131 | ; | |
132 | $config_help{"BUILD_TARGET"} = << "EOF" | |
133 | The location of the compiled file to copy to the target. | |
134 | (relative to OUTPUT_DIR) | |
135 | EOF | |
136 | ; | |
137 | $config_help{"TARGET_IMAGE"} = << "EOF" | |
138 | The place to put your image on the test machine. | |
139 | EOF | |
140 | ; | |
141 | $config_help{"POWER_CYCLE"} = << "EOF" | |
142 | A script or command to reboot the box. | |
143 | ||
144 | Here is a digital loggers power switch example | |
145 | POWER_CYCLE = wget --no-proxy -O /dev/null -q --auth-no-challenge 'http://admin:admin\@power/outlet?5=CCL' | |
146 | ||
147 | Here is an example to reboot a virtual box on the current host | |
148 | with the name "Guest". | |
149 | POWER_CYCLE = virsh destroy Guest; sleep 5; virsh start Guest | |
150 | EOF | |
151 | ; | |
152 | $config_help{"CONSOLE"} = << "EOF" | |
153 | The script or command that reads the console | |
154 | ||
155 | If you use ttywatch server, something like the following would work. | |
156 | CONSOLE = nc -d localhost 3001 | |
157 | ||
158 | For a virtual machine with guest name "Guest". | |
159 | CONSOLE = virsh console Guest | |
160 | EOF | |
161 | ; | |
162 | $config_help{"LOCALVERSION"} = << "EOF" | |
163 | Required version ending to differentiate the test | |
164 | from other linux builds on the system. | |
165 | EOF | |

167 | $config_help{"REBOOT_TYPE"} = << "EOF" | |
168 | Way to reboot the box to the test kernel. | |
169 | Only valid options so far are "grub" and "script". | |
170 | ||
171 | If you specify grub, it will assume grub version 1 | |
172 | and will search in /boot/grub/menu.lst for the title \$GRUB_MENU | |
173 | and select that target to reboot to the kernel. If this is not | |
174 | your setup, then specify "script" and have a command or script | |
175 | specified in REBOOT_SCRIPT to boot to the target. | |
176 | ||
177 | The entry in /boot/grub/menu.lst must be entered in manually. | |
178 | The test will not modify that file. | |
179 | EOF | |
180 | ; | |
181 | $config_help{"GRUB_MENU"} = << "EOF" | |
182 | The grub title name for the test kernel to boot | |
183 | (Only mandatory if REBOOT_TYPE = grub) | |
184 | ||
185 | Note, ktest.pl will not update the grub menu.lst, you need to | |
186 | manually add an option for the test. ktest.pl will search | |
187 | the grub menu.lst for this option to find what kernel to | |
188 | reboot into. | |
189 | ||
190 | For example, if in the /boot/grub/menu.lst the test kernel title has: | |
191 | title Test Kernel | |
192 | kernel vmlinuz-test | |
193 | GRUB_MENU = Test Kernel | |
194 | EOF | |
195 | ; | |
196 | $config_help{"REBOOT_SCRIPT"} = << "EOF" | |
197 | A script to reboot the target into the test kernel | |
