2018-03-02qapi: Generate in source orderMarkus Armbruster
The generators' conversion to visitors (merge commit 9e72681d16) changed the processing order of entities from source order to alphabetical order. The next commit needs source order, so change it back.

2018-03-02qapi: Record 'include' directives in parse treeMarkus Armbruster
The parse tree is a list of expressions. Except include expressions currently get replaced by the included file's parse tree. Instead of throwing away the include expression, keep it with the file name expanded so you don't have to track the including file's directory to make sense of it. A future commit will put this include expression to use.

2018-03-02qapi: Touch generated files only when they changeMarkus Armbruster
A massive number of objects depends on QAPI-generated headers. In my "build everything" tree, it's roughly 4800 out of 5100. This is particularly annoying when only some of the generated files change, say for a doc fix. Improve qapi-gen.py to touch its output files only if they actually change. Rebuild time for a QAPI doc fix drops from many minutes to a few seconds. Rebuilds get faster for certain code changes, too. For instance, adding a simple QMP event now recompiles less than 200 instead of 4800 objects. But adding a QAPI type is as bad as ever; we've clearly got more work to do.

2018-03-02qapi-gen: New common driver for code and doc generatorsMarkus Armbruster
Whenever qapi-schema.json changes, we run six programs eleven times to update eleven files. Similar for qga/qapi-schema.json. This is silly. Replace the six programs by a single program that spits out all eleven files. The programs become modules in new Python package qapi, along with the helper library. This requires moving them to scripts/qapi/. While moving them, consistently drop executable mode bits.

These classes encapsulate accumulating and writing output. Convert C code generation to QAPIGenC and QAPIGenH. The conversion is rather shallow: most of the output accumulation is not converted. Left for later. The indentation machinery uses a single global variable indent_level, even though we generally interleave creation of a .c and its .h. It should become instance variable of QAPIGenC. Also left for later. Documentation generation isn't converted, and QAPIGenDoc isn't used. This will change shortly.

2018-03-02hw/core/split-irq: Device that splits IRQ linesPeter Maydell
In some board or SoC models it is necessary to split a qemu_irq line so that one input can feed multiple outputs. We currently have qemu_irq_split() for this, but that has several deficiencies: * it can only handle splitting a line into two * it unavoidably leaks memory, so it can't be used in a device that can be deleted Implement a qdev device that encapsulates splitting of IRQs, with a configurable number of outputs. (This is in some ways the inverse of the TYPE_OR_IRQ device.)

2018-03-02qdev: Add new qdev_init_gpio_in_named_with_opaque()Peter Maydell
The function qdev_init_gpio_in_named() passes the DeviceState pointer as the opaque data pointor for the irq handler function. Usually this is what you want, but in some cases it would be helpful to use some other data pointer. Add a new function qdev_init_gpio_in_named_with_opaque() which allows the caller to specify the data pointer they want.

2018-03-02include/hw/or-irq.h: Add missing include guardPeter Maydell
The or-irq.h header file is missing the customary guard against multiple inclusion, which means compilation fails if it gets included twice. Fix the omission.

2018-03-02target/arm: Define init-svtor property for the reset secure VTOR valuePeter Maydell
The Cortex-M33 allows the system to specify the reset value of the secure Vector Table Offset Register (VTOR) by asserting config signals. In particular, guest images for the MPS2 AN505 board rely on the MPS2's initial VTOR being correct for that board. Implement a QEMU property so board and SoC code can set the reset value to the correct value.

Create an "idau" property on the armv7m container object which we can forward to the CPU object. Annoyingly, we can't use object_property_add_alias() because the CPU object we want to forward to doesn't exist until the armv7m container is realized.
