Markus Armbruster 62fff696d5 tests: Pass literal format strings directly to qmp_FOO()
The qmp_FOO() take a printf-like format string.  In a few places, we
assign a string literal to a variable and pass that instead of simply
passing the literal.  Clean that up.

Bonus: gets rid of non-literal format strings.  A step towards
compile-time format string checking without triggering
-Wformat-nonliteral.

Eric Blake 05e520f1c7 libqos: Use explicit QTestState for fw_cfg operations
Drop one more client of global_qtest by teaching all fw_cfg test
functionality (invoked through alloc-pc) to pass in an explicit
QTestState, adjusting all callers.  In particular, fw_cfg-test
had to reorder things to create the test state prior to creating
the fw_cfg (and drop a pointless strdup in the meantime), but that
test now no longer depends on global_qtest.

Eric Blake e5d1730d1e libqos: Track QTestState with QPCIBus
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).

Touch up some allocations to use g_new0() rather than g_malloc()
while in the area, and simplify some code (all implementations
of QOSOps provide a .init_allocator() that never fails).

David Gibson b4ba67d9a7 libqos: Change PCI accessors to take opaque BAR handle
The usual use model for the libqos PCI functions is to map a specific PCI
BAR using qpci_iomap() then pass the returned token into IO accessor
functions.  This, and the fact that iomap() returns a (void *) which
actually contains a PCI space address, kind of suggests that the return
value from iomap is supposed to be an opaque token.

..except that the callers expect to be able to add offsets to it.  Which
also assumes the compiler will support pointer arithmetic on a (void *),
and treat it as working with byte offsets.

To clarify this situation change iomap() and the IO accessors to take
a definitely opaque BAR handle (enforced with a wrapper struct) along with
an offset within the BAR.  This changes both the functions and all the
callers.

There were a number of places that checked if iomap() returned non-NULL,
and or initialized it to NULL before hand.  Since iomap() already assert()s
if it fails to map the BAR, these tests were mostly pointless and are
removed.

Markus Armbruster 041088c719 tests: Use proper functions types instead of void (*fn)
We have several function parameters declared as void (*fn).  This is
just a stupid way to write void *, and the only purpose writing it
like that could serve is obscuring the sin of bypassing the type
system without need.

The original sin is commit 49ee359: its qtest_add_func() is a wrapper
for g_test_add_func().  Fix the parameter type to match
g_test_add_func()'s.  This uncovers type errors in ide-test.c; fix
them.

Commit 7949c0e faithfully repeated the sin for qtest_add_data_func().
Fix it the same way, along with a harmless type error uncovered in
vhost-user-test.c.

Commit 063c23d repeated it for qtest_add_abrt_handler().  The screwy
parameter gets assigned to GHook member func, so change its type to
match.  Requires wrapping kill_qemu() to keep the type checker happy.

the cumulative duration of nsleep calls.

In practice, the timeout if inb() dwarfed the nsleep delays, and as a

So: change the semantics from "Not sooner than 5 seconds" to "no more
than 5 seconds" to ensure we don't hang the tester for very long.

John Snow 6ce7100e7f libqos: allow qpci_iomap to return BAR mapping size
This patch allows qpci_iomap to return the size of the
BAR mapping that it created, to allow driver applications
(e.g, ahci-test) to make determinations about the suitability
or the mapping size, or in the specific case of AHCI, how
many ports are supported by the HBA.

Kewei Yu b7fcff0179 qtest: Fix the bug about disable vnc causes "make check" fail
When we disable vnc from "./configure", QEMU can't use the vnc option.
So qtest can't use the "vnc -none ", otherwise "make check" fails.
If QEMU uses "-display none", "-vnc none" is excrescent, So we just need to drop it.

Stefan Hajnoczi 0d1aa05e9e libqtest: rename qmp() to qmp_discard_response()
Existing qmp() callers do not expect a response object.  In order to
implement real QMP test cases it will be necessary to inspect the
response object.

Rename qmp() to qmp_discard_response().  Later patches will introduce a
qmp() function that returns the response object and tests that use it.

Michael Roth 22bfa16ed3 ide-test: fix failure for test_flush
bd07684aac added a test to ensure BSY
flag is set when a flush request is in flight. It does this by setting
a blkdebug breakpoint on flush_to_os before issuing a CMD_FLUSH_CACHE.
It then resumes CMD_FLUSH_CACHE operation and checks that BSY is unset.

The actual unsetting of BSY does not occur until ide_flush_cb gets
called in a bh, however, so in some cases this check will race with
the actual completion.

Fix this by polling the ide status register until BSY flag gets unset
before we do our final sanity checks. According to
f68ec8379e this is in line with how a guest
would determine whether or not the device is still busy.
