Since the mac99 and g3beige PowerPC machines recently broke without being noticed, it would be good to have a tester for "make check" that detects such issues immediately. A simple way to test the firmware of these machines is to use the "-prom-env" parameter of QEMU. This parameter can be used to put some Forth code into the 'boot-command' firmware variable which then can signal success to the tester by writing a magic value to a known memory location. And since some of the Sparc machines are also using OpenBIOS, they are now tested with this prom-env-tester, too.

* This test is used to check that some OpenBIOS machines can be started
|
|
* successfully in TCG mode. To do this, we first put some Forth code into
|
|
* the "boot-command" Open Firmware environment variable. This Forth code
|
|
* writes a well-known magic value to a known location in memory. Then we
|
|
* start the guest so that OpenBIOS can boot and finally run the Forth code.
|
|
* The testing code here then can finally check whether the value has been
|
|
* successfully written into the guest memory.
