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

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