2016-07-04hw/arm/virt: mark the PCIe host controller as DMA coherent in the DTArd Biesheuvel
Since QEMU performs cacheable accesses to guest memory when doing DMA as part of the implementation of emulated PCI devices, guest drivers should use cacheable accesses as well when running under KVM. Since this essentially means that emulated PCI devices are DMA coherent, set the 'dma-coherent' DT property on the PCIe host controller DT node. This brings the DT description into line with the ACPI description, which already marks the PCI bridge as cache coherent (see commit bc64b96c984abf).

2016-07-04armv7m_nvic: Use qemu_get_cpu(0) instead of current_cpuAndrey Smirnov
Starting QEMU with -S results in current_cpu containing its initial value of NULL. It is however possible to connect to such QEMU instance and query various CPU registers, one example being CPUID, and doing that results in QEMU segfaulting. Using qemu_get_cpu(0) seem reasonable enough given that ARMv7M architecture is a single core architecture.

2016-07-04memory: Assert that memory_region_init_rom_device() ops aren't NULLPeter Maydell
It doesn't make sense to pass a NULL ops argument to memory_region_init_rom_device(), because the effect will be that if the guest tries to write to the memory region then QEMU will segfault. Catch the bug earlier by sanity checking the arguments to this function, and remove the misleading documentation that suggests that passing NULL might be sensible.

Provide a new helper function memory_region_init_rom() for memory regions which are read-only (and unlike those created by memory_region_init_rom_device() don't have special behaviour for writes). This has the same behaviour as calling memory_region_init_ram() and then memory_region_set_readonly() (which is what we do today in boards with pure ROMs) but is a more easily discoverable API for the purpose.

2016-07-04target-arm/arm-semi.c: Fix SYS_HEAPINFO for 64-bit guestsPeter Maydell
SYS_HEAPINFO is one of the few semihosting calls which has to write values back into a parameter block in memory. When we added support for 64-bit semihosting we updated the code which reads from the parameter block to read 64-bit words but forgot to change the code that writes back into the block. Update it to treat the block as a set of words of the appropriate width for the guest.

2016-07-04virtio: set low features early on loadMichael S. Tsirkin
virtio migrates the low 32 feature bits twice, the first copy is there for compatibility but ever since 019a3edbb25f1571e876f8af1ce4c55412939e5d: ("virtio: make features 64bit wide") it's ignored on load. This is wrong since virtio_net_load tests self announcement and guest offloads before the second copy including high feature bits is loaded. This means that self announcement, control vq and guest offloads are all broken after migration. Fix it up by loading low feature bits: somewhat ugly since high and low bits become out of sync temporarily, but seems unavoidable for compatibility. The right thing to do for new features is probably to test the host features, anyway.

2016-07-04pc: Eliminate PcPciInfoMarkus Armbruster
PcPciInfo has two (ill-named) members: Range w32 is the PCI hole, and w64 is the PCI64 hole. Three users: * I440FXState and MCHPCIState have a member PcPciInfo pci_info, but only pci_info.w32 is actually used. This is confusing. Replace by Range pci_hole. * acpi_build() uses auto PcPciInfo pci_info to forward both PCI holes from acpi_get_pci_info() to build_dsdt(). Replace by two variables Range pci_hole, pci_hole64.

2016-07-04piix: Set I440FXState member pci_info.w32 in one placeMarkus Armbruster
Range pci_info.w32 records the location of the PCI hole. It's initialized to empty when QOM zeroes I440FXState. That's a fine value for a still unknown PCI hole. i440fx_init() sets pci_info.w32.begin = below_4g_mem_size. Changes the PCI hole from empty to [below_4g_mem_size, UINT64_MAX]. That's a bogus value. i440fx_pcihost_initfn() sets pci_info.end = IO_APIC_DEFAULT_ADDRESS. Since i440fx_init() ran already, this changes the PCI hole to [below_4g_mem_size, IO_APIC_DEFAULT_ADDRESS-1]. That's the correct value. Setting the bounds of the PCI hole in two separate places is confusing, and begs the question whether the bogus intermediate value could be used by something, or what would happen if we somehow managed to realize an i440FX device without having run the board init function i440fx_init() first. Avoid the confusion by setting the (constant) upper bound along with the lower bound in i440fx_init(). Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Michael S.

2016-07-04xen: fix ram init regressionGerd Hoffmann
Commit "8156d48 pc: allow raising low memory via max-ram-below-4g option" causes a regression on xen, because it uses a different memory split. This patch initializes max-ram-below-4g to zero and leaves the initialization to the memory initialization functions. That way they can pick different default values (max-ram-below-4g is zero still) or use the user supplied value (max-ram-below-4g is non-zero). Also skip the whole ram split calculation on Xen. xen_ram_init() does its own split calculation anyway so it is superfluous, also this way xen_ram_init can actually see whenever max-ram-below-4g is zero or not.

2016-07-04crypto: switch hash code to use nettle/gcrypt directlyDaniel P. Berrange
Currently the internal hash code is using the gnutls hash APIs. GNUTLS in turn is wrapping either nettle or gcrypt. Not only were the GNUTLS hash APIs not added until GNUTLS 2.9.10, but they don't expose support for all the algorithms QEMU needs to use with LUKS. Address this by directly wrapping nettle/gcrypt in QEMU and avoiding GNUTLS's extra layer of indirection. This gives us support for hash functions on a much wider range of platforms and opens up ability to support more hash functions. It also avoids a GNUTLS bug which would not correctly handle hashing of large data blocks if int != size_t. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>

2016-07-04crypto: fix handling of iv generator hash defaultsDaniel P. Berrange
When opening an existing LUKS volume, if the iv generator is essiv, then the iv hash algorithm is mandatory to provide. We must report an error if it is omitted in the cipher mode spec, not silently default to hash 0 (md5). If the iv generator is not essiv, then we explicitly ignore any iv hash algorithm, rather than report an error, for compatibility with dm-crypt. When creating a new LUKS volume, if the iv generator is essiv and no iv hsah algorithm is provided, we should default to using the sha256 hash.

2016-07-01spapr: drop reference on child object during core realizationGreg Kurz
When a core is being realized, we create a child object for each thread of the core. The child is first initialized with object_initialize() which sets its ref count to 1, and then added to the core with object_property_add_child() which bumps the ref count to 2. When the core gets released, object_unparent() decreases the ref count to 1, and we g_free() the object: we hence loose the reference on an unfinalized object. This is likely to cause random crashes. Let's drop the extra reference as soon as we don't need it, after the thread is added to the core.

Introduction of core based CPU hotplug for PowerPC sPAPR didn't add support for 970MP and POWER8NVL based core types. Add support for the same. While we are here, add support for explicit specification of POWER5+_v2.1 core type.

2016-07-01target-ppc: gen_pause for instructions: yield, mdoio, mdoom, misoAaron Larson
Call gen_pause for all "or rx,rx,rx" encodings other nop. This provides a reasonable implementation for yield, and a better approximation for mdoio, mdoom, and miso. The choice to pause for all encodings !=0 leverages the PowerISA admonition that the reserved encodings might change program priority, providing a slight "future proofing".

2016-07-01ppc/xics: Replace "icp" with "xics" in most placesBenjamin Herrenschmidt
The "ICP" is a different object than the "XICS". For historical reasons, we have a number of places where we name a variable "icp" while it contains a XICSState pointer. There *is* an ICPState structure too so this makes the code really confusing. This is a mechanical replacement of all those instances to use the name "xics" instead. There should be no functional change.
