      qom: Put name parameter before value / visitor parameter · 5325cc34
      Markus Armbruster authored 
      
The object_property_set_FOO() setters take property name and value in
an unusual order:

    void object_property_set_FOO(Object *obj, FOO_TYPE value,
                                 const char *name, Error **errp)

Having to pass value before name feels grating.  Swap them.

Same for object_property_set(), object_property_get(), and
object_property_parse().

Convert callers with this Coccinelle script:

    @@
    identifier fun = {
        object_property_get, object_property_parse, object_property_set_str,
        object_property_set_link, object_property_set_bool,
        object_property_set_int, object_property_set_uint, object_property_set,
        object_property_set_qobject
    };
    expression obj, v, name, errp;
    @@
    -    fun(obj, v, name, errp)
    +    fun(obj, name, v, errp)

Chokes on hw/arm/musicpal.c's lcd_refresh() with the unhelpful error
message "no position information".  Convert that one manually.

Fails to convert hw/arm/armsse.c, because Coccinelle gets confused by
ARMSSE being used both as typedef and function-like macro there.
Convert manually.

Fails to convert hw/rx/rx-gdbsim.c, because Coccinelle gets confused
by RXCPU being used both as typedef and function-like macro there.
Convert manually.  The other files using RXCPU that way don't need
conversion.

The first rule exempts hw/arm/highbank.c, because it matches along two
control flow paths there, with different @type_name.  Covered by the
next commit's manual conversions.

Missing #include "qapi/error.h" added manually.

      hw/mips/mips_jazz: Remove no-longer-necessary override of do_unassigned_access · 6626286e
      Peter Maydell authored 
      
Now that the MIPS CPU implementation uses the new
do_transaction_failed hook, we can remove the old code that handled
the do_unassigned_access hook.

      hw/mips/mips_jazz: Override do_transaction_failed hook · 8d2b8718
      Peter Maydell authored 
      The MIPS Jazz ('magnum' and 'pica61') boards have some code which
overrides the CPU's do_unassigned_access hook, so they can intercept
it and not raise exceptions on data accesses to invalid addresses,
only for instruction fetches.

We want to switch MIPS over to using the do_transaction_failed
hook instead, so add an intercept for that as well, and make
the board code install whichever hook the CPU is actually using.
Once we've changed the CPU implementation we can remove the
redundant code for the old hook.

Note: I am suspicious that the behaviour as implemented here may not
be what the hardware really does.  It was added in commit
54e75558 to restore the behaviour that was broken by
commit c658b94f.  But prior to commit c658b94f
every MIPS board generated exceptions for instruction access to
invalid addresses but not for data accesses; and other boards,
notably Malta, were fixed by making all invalid accesses behave as
reads-as-zero (see the call to empty_slot_init() in
mips_malta_init()).  Hardware that raises exceptions for instruction
access and not data access seems to me to be an unlikely design, and
it's possible that the right way to emulate this is to make the Jazz
boards do what we did with Malta (or some variation of that).
Nonetheless, since I don't have access to real hardware to test
against I have taken the approach of "make QEMU continue to behave
the same way it did before this commit".  I have updated the comment
to correct the parts that are no longer accurate and note that
the hardware might behave differently.

The test case for the need for the hook-hijacking is in
https://bugs.launchpad.net/qemu/+bug/1245924

 That BIOS will boot OK
either with this overriding of both hooks, or with a simple "global
memory region to ignore bad accesses of all types", so it doesn't
provide evidence either way, unfortunately.
