2016-01-13omap: Don't use hw_error() in device init() methodsMarkus Armbruster1-2/+6
Device init() methods aren't supposed to call hw_error(), they should report the error and fail cleanly. Do that. The errors are all device misconfiguration. All callers use qdev_init_nofail(), so this patch merely converts hw_error() crashes into &error_abort crashes. Improvement, because now it crashes closer to where the misconfiguration bug would be, and a few more bad examples of hw_error() use are gone.

2013-12-24hw: cannot_instantiate_with_device_add_yet due to pointer propsMarkus Armbruster2-0/+4
Pointer properties can be set only by code, not by device_add. A device with a pointer property can work with device_add only when the property may remain null. This is the case for property "interrupt_vector" of device "etraxfs,pic". Add a comment there. Set cannot_instantiate_with_device_add_yet for the other devices with pointer properties, with a comment explaining why. Juha Riihimäki and Peter Maydell deserve my thanks for making "pointer property must not remain null" blatantly obvious in the OMAP devices. Only device "smbus-eeprom" is actually changed. The others are all sysbus devices, which get cannot_instantiate_with_device_add_yet set in their abstract base's class init function. Setting it again in their class init function is technically redundant, but serves as insurance for when sysbus devices become available with device_add, and as documentation.

An ICH9 southbridge contains several PCI devices, some of them with multiple functions. We model each function as a separate qdev. Two of them need some special wiring set up in pc_q35_init() to work: the LPC controller at 00:1f.0, and the SMBus controller at 00:1f.3.

2013-12-23qdev: Replace no_user by cannot_instantiate_with_device_add_yetMarkus Armbruster1-1/+1
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.

2013-07-23hw: Avoid use of QOM type name macros in VMStateDescriptionsPeter Maydell1-1/+1
The name field in a VMStateDescription is part of the migration state versioning, so changing it will break migration. It's therefore a bad idea to use a QOM typename macro to initialize it, because in general we're free to rename QOM types as part of code refactoring and cleanup. For the handful of devices that were doing this by mistake, replace the QOM typenames with the corresponding literal strings.
