◆ test_main()

void test_main ( void )

To be implemented by each test, as its entry point.

Todo:: Implement better command line infrastructure, but this will do for now.

At the time of writing, Xen doesn't correctly handle invlpg while running in shadow mode on AMD Gen1 hardware lacking decode assistance. For this test, we simply care that Xen doesn't crash.
