2019-03-19xen-mapcache: use MAP_FIXED flag so the mmap address hint is always honoredRoger Pau Monne
Or if it's not possible to honor the hinted address an error is returned instead. This makes it easier to spot the actual failure, instead of failing later on when the caller of xen_remap_bucket realizes the mapping has not been created at the requested address. Also note that at least on FreeBSD using MAP_FIXED will cause mmap to try harder to honor the passed address.

2019-03-19RISC-V: Allow interrupt controllers to claim interruptsMichael Clark
We can't allow the supervisor to control SEIP as this would allow the supervisor to clear a pending external interrupt which will result in lost a interrupt in the case a PLIC is attached. The SEIP bit must be hardware controlled when a PLIC is attached. This logic was previously hard-coded so SEIP was always masked even if no PLIC was attached. This patch adds riscv_cpu_claim_interrupts so that the PLIC can register control of SEIP. In the case of models without a PLIC (spike), the SEIP bit remains software controlled. This interface allows for hardware control of supervisor timer and software interrupts by other interrupt controller models.

2019-03-19spapr: Correctly set LPCR[GTSE] in H_REGISTER_PROCESS_TABLEDavid Gibson
176dccee "target/ppc/spapr: Clear partition table entry when allocating hash table" reworked the H_REGISTER_PROCESS_TABLE hypercall, but unfortunately due to a small error no longer correctly sets the LPCR[GTSE] bit which allows the guest to directly execute (some types of) tlbie (TLB flush) instructions without involving the hypervisor. We got away with this, initially, because POWER9 did not have hypervisor mode enabled in its msr_mask, which meant we didn't actually run hypervisor privilege checks in TCG at all. However, da874d90 "target/ppc: add HV support for POWER9" turned on HV support on POWER9 for the benefit of the powernv machine type. This exposed the earlier bug in H_REGISTER_PROCESS_TABLE, and causes guests which rely on LPCR[GTSE] (i.e. basically all of them) to crash during early boot when their first tlbie instruction causes an unexpected trap.

This patch fixes two issues in the hppa/parisc emulation: 1. The CPU HPA was wrong in the sense that we had negative module offsets in the firmware-internal module table (which we ignored up to now). Get it correct by changing the CPU HPA to 0xfffb0000 which is greater than the DINO_HPA of 0xfff80000. This change requires the seabios-firmware update. 2.

2019-03-12i386, acpi: check acpi_memory_hotplug capacity in pre_plugWei Yang
Currently we do device realization like below: hotplug_handler_pre_plug() dc->realize() hotplug_handler_plug() Before we do device realization and plug, we should allocate necessary resources and check if memory-hotplug-support property is enabled. At the piix4 and ich9, the memory-hotplug-support property is checked at plug stage. This means that device has been realized and mapped into guest address space 'pc_dimm_plug()' by the time acpi plug handler is called, where it might fail and crash QEMU due to reaching g_assert_not_reached() (piix4) or error_abort (ich9). Fix it by checking if memory hotplug is enabled at pre_plug stage where we can gracefully abort hotplug request.

2019-03-12gen_pcie_root_port: Add ACS (Access Control Services) capabilityKnut Omang
Claim ACS support in the generic PCIe root port to allow passthrough of individual functions of a device to different guests (in a nested virt.setting) with VFIO. Without this patch, all functions of a device, such as all VFs of an SR/IOV device, will end up in the same IOMMU group. A similar situation occurs on Windows with Hyper-V. In the single function device case, it also has a small cosmetic benefit in that the root port itself is not grouped with the device. VFIO handles that situation in that binding rules only apply to endpoints, so it does not limit passthrough in those cases.

2019-03-12pcie: Add a simple PCIe ACS (Access Control Services) helper functionKnut Omang
Implementing an ACS capability on downstream ports and multifunction endpoints indicates isolation and IOMMU visibility to a finer granularity. This creates smaller IOMMU groups in the guest and thus more flexibility in assigning endpoints to guest userspace or an L2 guest.

2019-03-12vhost-user: Support transferring inflight buffer between qemu and backendXie Yongji
This patch introduces two new messages VHOST_USER_GET_INFLIGHT_FD and VHOST_USER_SET_INFLIGHT_FD to support transferring a shared buffer between qemu and backend. Firstly, qemu uses VHOST_USER_GET_INFLIGHT_FD to get the shared buffer from backend. Then qemu should send it back through VHOST_USER_SET_INFLIGHT_FD each time we start vhost-user. This shared buffer is used to track inflight I/O by backend. Qemu should retrieve a new one when vm reset.

Intel(R) VT-d 3.0 spec introduces scalable mode address translation to replace extended context mode. This patch extends current emulator to support Scalable Mode which includes root table, context table and new pasid table format change. Now intel_iommu emulates both legacy mode and scalable mode (with legacy-equivalent capability set). The key points are below: 1. Extend root table operations to support both legacy mode and scalable mode. 2. Extend context table operations to support both legacy mode and scalable mode. 3. Add pasid tabled operations to support scalable mode.
