Defined at line 543 of file ../../src/devices/usb/drivers/dwc3/dwc3-test-fixture.h

Test is templated on a parameter which, if true, will have the harness start and stop the driver.

Otherwise, it is the individual test(s) responsibility to start and stop the driver.

zx_status_t WaitForPhy ()

There's an inherent race in the way this test is set up between the three threads: the

foreground testing thread, the background driver thread, and the environment thread the fakes

are running on. Driving the driver's dispatcher to an idle state and then tearing down the test

will race with the environment's dispatcher execution of the Watch handler. If the environment

dispatcher is torn down before the side effects of the Watch handler execute, ~FakeUsbPhy()

will sometimes fail. To resolve this race, the foreground testing thread needs to be

synchronized against the environment thread and wait for the fakes to catch up.
