If QEMU has been compiled with the flags --enable-tcg-interpreter and --enable-debug, the guest is running incredibly slow. The prom-env test is approximately 10 times slower than normal in this case, and it takes up to 500 seconds until the test with the pseries machine finishs. While we should still look for ways to speed up the test on the pseries machine here, let's bump the timeout to 600 seconds to allow the test to pass with this unusal configuration already now. Also move the pseries test into the "slow" category - since it is really a very slow test. Reviewed-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Thomas Huth <thuth@redhat.com>

* This test is used to check that some Open Firmware based machines (i.e.
|
|
* OpenBIOS or SLOF) 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 the firmware 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.
