2015-09-07s390: move memory calculation into the sclp deviceDavid Hildenbrand3-66/+68
The restrictions for memory calculation belong to the sclp device. Let's move the calculation to that point, so we are able to unify it for both s390 machines. The sclp device is the first device to be initialized. It performs the calculation and safely stores it in the machine, where other parts of the system can access an reuse it. The memory hotplug device is now only created when it is really needed.

2015-09-07s390/sclp: ignore memory hotplug operations if it is disabledDavid Hildenbrand1-7/+26
If no memory hotplug device was created, the sclp command facility is not exposed (SCLP_FC_ASSIGN_ATTACH_READ_STOR). We therefore have no memory hotplug and should correctly report SCLP_RC_INVALID_SCLP_COMMAND if any such command is executed. This gets rid of these ugly asserts that could have been triggered for the s390-virtio machine.

2015-09-07s390/sclp: temporarily fix unassignment/reassignment of memory subregionsDavid Hildenbrand1-2/+8
Commit 374f2981d1f1 ("memory: protect current_map by RCU") broke unassignment of standby memory on s390x. Looks like that the new parallelism allows races with our (semi broken) memory hotplug code. The flatview_unref() can now be executed after our unparenting. Therefore memory_region_unref() tries to unreference the MemoryRegion itself instead of the parent. In theory, MemoryRegions are now bound to separate devices that control their lifetime. We don't have this yet, so we really want to control their lifetime manually. This patch fixes it temporarily, until we have a proper rework. The only drawback is that they won't pop up in "info qom-tree", but that's better than qemu crashes. We have to release the reference to a memory region after a memory_region_find, as it automatically takes a reference. As we're now able to reassign memory, the MemoryRegion is in fact deleted (otherwise vmstate_register_ram() would complain).

2015-09-07s390/sclp: rework sclp event facility initialization + device realizationDavid Hildenbrand2-19/+34
The current code only works by chance. The event facility is a sysbus device, but specifies in its class structure as parent the DeviceClass (instead of a device class). The init function in return lies therefore at the same position as the init function of SysBusDeviceClass and gets triggered instead - a very bad idea of doing that (e.g. the parameter types don't match). Let's bring the initialization code up to date, initializing the event facility + child events in .instance_init and moving the realization of the child events out of the init call, into the realization step. Device realization is now automatically performed when the event facility itself is realized. That realization implicitly triggers realization of the child bus, which in turn initializes the events. Please note that we have to manually propagate the realization of the bus children, common code still has a TODO set for that task.

Let's get rid of this strange local variable + irq logic and work directly on the QOM. (hint: what happens if two such devices are created?) We could introduce proper QOM class + state for the cpu hotplug device, however that would result in too much overhead for a simple "trigger_signal" function. Also remove one unnecessary class function initialization.

2015-09-07s390x/kvm: make setting of in-kernel irq routes more efficientJens Freimann2-1/+2
When we add new adapter routes we call kvm_irqchip_add_route() for every virtqueue and in the same step also do the KVM_SET_GSI_ROUTING ioctl. This is unnecessary costly as the interface allows us to set multiple routes in one go. Let's first add all routes to the table stored in the global kvm_state and then do the ioctl to commit the routes to the in-kernel irqchip. This saves us several ioctls to the kernel where for each call a list is reallocated and populated.

2015-09-07s390x/css: start with cleared cstat/dstatCornelia Huck1-0/+2
When executing the start function, we should start with a clear state regarding subchannel and device status; it is easy to forget updating one of them after the ccw has been processed. Note that we don't need to care about resetting the various control fields: They are cleared by tsch(), and if they were still pending, we wouldn't be able to execute the start function in the first place. Also note that we don't want to clear cstat/dstat if a suspended subchannel is resumed. This fixes a bug where we would continue to present channel-program check in cstat even though later ccw requests for the subchannel finished without error (i.e. cstat should be 0).

Since the pow2floor() function is now used in a hot code path, make it inline; for consistency, provide pow2ceil() as an inline function too. Because these functions use ctz64() we have to put the inline versions into host-utils.h, so they have access to ctz64(), and move the inline is_power_of_2() along with them. We then need to include host-utils.h from qemu-common.h so that the files which use these functions via qemu-common.h still have access to them.

A couple of places in hw/pci use an inline calculation to round a size up to the next largest power of 2. We have a utility routine for this, so use it. (The behaviour of the old code is different if the size value is 0 -- it would leave it as 0 rather than rounding up to 1, but in both cases we know the size can't be 0. In the case where the size value had bit 31 set, the old code would invoke undefined behaviour; the new code will give a result of 0. Presumably that could never happen either.)

2015-09-07i.MX: KZM: use standalone i.MX31 SOC supportJean-Christophe Dubois5-186/+102
Convert the KZM board to use the i.MX31 SoC defintition instead of redefining the entire SoC on the machine level. Major rewrite of the machine init code. While touching the memory map comment de-indent to the correct level of indentation. This obsoletes the legacy i.MX device device creation helpers which are removed. Tested by booting a minimal Linux system on the emulated platform Signed-off-by: Jean-Christophe Dubois <jcd@tribudubois.net> Reviewed-by: Peter Crosthwaite <crosthwaite.peter@gmail.com> Message-id: 5e783561f092e1c939562fdff001f1ab1194b07f.1441057361.git.jcd@tribudubois.net Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2015-09-07hw/arm/virt: Add high MMIO PCI region, 512G in sizePavel Fedin4-9/+76
This large region is necessary for some devices like ivshmem and video cards 32-bit kernels can be built without LPAE support. In this case such a kernel will not be able to use PCI controller which has windows in high addresses. In order to work around the problem, "highmem" option is introduced. It defaults to on on, but can be manually set to off in order to be able to run those old 32-bit guests.
