2018-12-17tests/prom-env: Make test independent of global_qtestThomas Huth
global_qtest is only needed here for one readl(). Let's replace it with qtest_readl() and we can remove the global_qtest variable here. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>
2018-08-16libqtest: Replace qtest_startf() by qtest_initf()Markus Armbruster
qtest_init() creates a new QTestState, and leaves @global_qtest alone. qtest_start() additionally assigns it to @global_qtest, but qtest_startf() additionally assigns NULL to @global_qtest. This makes no sense. Replace it by qtest_initf() that works like qtest_init(), i.e. leaves @global_qtest alone.

2017-10-20libqtest: Add qtest_[v]startf()Eric Blake
We have several callers that were formatting the argument strings themselves; consolidate this effort by adding new convenience functions directly in libqtest, and update some call-sites that can benefit from it. Note that the new functions qtest_startf() and qtest_vstartf() behave more like qtest_init() (the caller must assign global_qtest after the fact, rather than getting it implicitly set). This helps us prepare for future patches that get rid of the global variable, by explicitly highlighting which tests still depend on it now.

2017-10-16tests/prom-env: Bump the timeout, and test pseries only in slow modeThomas Huth
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>
2017-02-28tests/prom-env: Enable the test for the sun4u machine, tooThomas Huth
The 32-bit TCG bug has been fixed a while ago, so we can enable this test for sparc64 now, too. Unfortunately, OpenBIOS does not work with the sun4v machine anymore (it needs to catch up with the improved emulation), so we can only enable this test for the sun4u machine right now.

2017-02-10tests/prom-env: Ease time-out problems on slow hostsThomas Huth
Peter Maydell recently ran into time-out problems with the prom-env test on a rather slow ARM board. To tackle this issue, we can speed up the test by running QEMU with "-nodefaults" for the pseries machine, so that SLOF has less devices to scan during boot, and by using the "nvramrc" environment variable instead of "boot-command", since this variable is evaluated earlier in the boot process. And to be really sure that we do not face such time out problems again, let's also increase the time out value from 100s to 120s instead.

2016-10-28tests: Add pseries machine to the prom-env-test, tooDavid Gibson
Now that we also support the "-prom-env" parameter for the pseries machine, we can enable this test for this machine, too. Since booting with TCG is rather slow with the pseries machine, we also enable the "-nodefaults" parameter for this test now, so that SLOF does not have to check that much devices during boot and thus runs a little bit faster.

2016-06-17ppc / sparc: Add a tester for checking whether OpenBIOS runs successfullyThomas Huth
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.
