Hi Eric,
On 09/01/2017 03:03 PM, Eric Blake wrote:
When initializing a QPCIBus, track which QTestState the bus is
associated with (so that a later patch can then explicitly use
that test state for all communication on the bus, rather than
blindly relying on global_qtest). Update the initialization
functions to take another parameter, and update all callers to
pass in state (for now, most callers get away with passing the
current global_qtest as the current state, although this required
fixing the order of initialization to ensure qtest_start() is
called before qpci_init*() in rtl8139-test, and provided an
opportunity to pass in the allocator in e1000e-test).
