12 | * This test is used to check that some Open Firmware based machines (i.e. |
13 | * OpenBIOS or SLOF) can be started successfully in TCG mode. To do this, we | |
14 | * first put some Forth code into the "boot-command" Open Firmware environment | |
15 | * variable. This Forth code writes a well-known magic value to a known location | |
16 | * in memory. Then we start the guest so that the firmware can boot and finally | |
17 | * run the Forth code. | |
fcbf4a3c TH |
18 | * The testing code here then can finally check whether the value has been |
19 | * successfully written into the guest memory. | |
