2014-03-20vl.c: Extend get_boot_devices_list() to ignore suffixesAlexey Kardashevskiy
As suffixes do not make sense for sPAPR's device tree and there is no way to filter them out on the BusState::get_fw_dev_path() level, let's add an ability for the external caller to specify whether to apply suffixes or not. We could handle suffixes in SLOF (ignored for now) but this would require serious rework in the node opening code in SLOF, which has no obvious benefit for the currently emulated sPAPR machine.

2013-12-23sysbus: Set cannot_instantiate_with_device_add_yetMarkus Armbruster
device_add plugs devices into suitable bus. For "real" buses, that actually connects the device. For sysbus, the connections need to be made separately, and device_add can't do that. The device would be left unconnected, and could not possibly work. Quite a few, but not all sysbus devices already set cannot_instantiate_with_device_add_yet in their class init function. Set it in their abstract base's class init function sysbus_device_class_init(), and remove the now redundant assignments from device class init functions.

2013-12-23qdev: Replace no_user by cannot_instantiate_with_device_add_yetMarkus Armbruster
In an ideal world, machines can be built by wiring devices together with configuration, not code. Unfortunately, that's not the world we live in right now. We still have quite a few devices that need to be wired up by code. If you try to device_add such a device, it'll fail in sometimes mysterious ways. If you're lucky, you get an unmysterious immediate crash. To protect users from such badness, DeviceClass member no_user used to make device models unavailable with -device / device_add, but that regressed in commit 18b6dad. The device model is still omitted from help, but is available anyway. Attempts to fix the regression have been rejected with the argument that the purpose of no_user isn't clear, and it's prone to misuse. This commit clarifies no_user's purpose. Anthony suggested to rename it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which I shorten somewhat to keep checkpatch happy. While there, make it bool. Every use of cannot_instantiate_with_device_add_yet gets a FIXME comment asking for rationale. The next few commits will clean them all up, either by providing a rationale, or by getting rid of the use. With that done, the regression fix is hopefully acceptable.

2013-08-07fw_cfg: the I/O port variant expects little-endianPaolo Bonzini
The I/O port variant of fw_cfg is used by sparc64, which is a big-endian machine. Firmware swaps bytes before sending them to fw_cfg, so we need to unswap them in the device. This is only used on sparc64 and on (little-endian) x86, so it does not affect any other target. 32-bit Sparc and PPC all use memory-mapped fw_cfg.

2013-07-01spapr-rtas: add CPU argument to RTAS callsAnthony Liguori
RTAS is a hypervisor provided binary blob that a guest loads and calls into to execute certain functions. It's similar to the vsyscall page in Linux or the short lived VMCI paravirt interface from VMware. The QEMU implementation of the RTAS blob is simply a passthrough that proxies all RTAS calls to the hypervisor via an hypercall. While we pass a CPU argument for hypercall handling in QEMU, we don't pass it for RTAS calls. Since some RTAs calls require making hypercalls (normally RTAS is implemented as guest code) we have nasty hacks to allow that. Add a CPU argument to RTAS call handling so we can more easily invoke hypercalls just as guest code would.

2013-04-26pseries: Convert VIO code to QOM style type safe(ish) castsDavid Gibson
Curerntly the pseries VIO device code contains quite a few explicit uses of DO_UPCAST and plain C casts. This is (obviously) type unsafe, and not the conventional way of doing things in the QOM model. This patch converts the code to use the QOM convention of per-type macros to do verified casts with OBJECT_CHECK().
