* Include hw/qdev-properties.h lessMarkus Armbruster2019-08-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead. hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h. While there, delete a few superfluous inclusions of hw/qdev-core.h. Touching hw/qdev-properties.h now recompiles some 1200 objects.

* hw/core/sysbus: Add a function for creating and attaching an objectThomas Huth2018-07-171-0/+17
| | | | | | | | | | | | | | | A lot of functions are initializing an object and attach it immediately afterwards to the system bus. Provide a common function for this, which also uses object_initialize_child() to make sure that the reference counter is correctly initialized to 1 afterwards.

* sysbus: Remove ignored return value of FindSysbusDeviceFuncDavid Gibson2016-09-271-1/+1
| | | | | | | | | | | | | Functions of type FindSysbusDeviceFunc currently return an integer. However, this return value is always ignored by the caller in find_sysbus_device(). This changes the function type to return void, to avoid confusion over the function semantics.

* hw: remove pio_addr_tPaolo Bonzini2016-05-191-2/+2
| | | | | | | | | | | | | | | pio_addr_t is almost unused, because these days I/O ports are simply accessed through the address space. cpu_{in,out}[bwl] themselves are almost unused; monitor.c and xen-hvm.c could use address_space_read/write directly, since they have an integer size at hand. This leaves qtest as the only user of those functions. On the other hand even portio_* functions use this type; the only interesting use of pio_addr_t thus is include/hw/sysbus.h. I guess I could move it there, but I don't see much benefit in that either. Using uint32_t is enough and avoids the need to include ioport.h everywhere.

* hw/core: explicit OFW unit address callback for SysBusDeviceClassLaszlo Ersek2015-06-231-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | The sysbus_get_fw_dev_path() function formats OpenFirmware device path nodes ("driver-name@unit-address") for sysbus devices. The first choice for "unit-address" is the base address of the device's first MMIO region. The second choice is its first IO port. However, if two sysbus devices with the same "driver-name" lack both MMIO and PIO resources, then there is no good way to distinguish them based on their OFW nodes, because in this case unit-address is omitted completely for both devices. An example is TYPE_PXB_HOST ("pxb-host"). For the sake of such devices, introduce the explicit_ofw_unit_address() "virtual member function". With this function, each sysbus device in the same SysBusDeviceClass can state its own address. Cc: Markus Armbruster <armbru@redhat.com> Cc: Marcel Apfelbaum <marcel@redhat.com> Cc: Michael S.

* | sysbus: Expose MMIO enumeration helperAlexander Graf2014-11-041-0/+1
| | | | | | | | | | | | | | | | | | | | Sysbus devices have a range of MMIO regions they expose. The exact number of regions is device specific and internal information to the device model. Expose whether a region exists via a public interface. That way our platform bus enumeration code can dynamically determine how many regions exist. Signed-off-by: Alexander Graf <agraf@suse.de>

| | | | | | | | | | | | | | | | | | | | | | Sysbus devices can get their IRQ lines connected to other devices. It is possible to figure out which IRQ line a connection is on and whether a sysbus device even provides an IRQ connector at a specific offset.

* memory: Change MemoryRegion priorities from unsigned to signedMarcel Apfelbaum2013-10-141-1/+1
| | | | | | | | | | | | | | | | When memory regions overlap, priority can be used to specify which of them takes priority. By making the priority values signed rather than unsigned, we make it more convenient to implement a situation where one "background" region should appear only where no other region exists: rather than having to explicitly specify a high priority for all the other regions, we can let them take the default (zero) priority and specify a negative priority for the background region.

Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.
