2014-06-04kvm: Fix eax for cpuid leaf 0x40000000Jidong Xiao
Since Linux kernel 3.5, KVM has documented eax for leaf 0x40000000 to be KVM_CPUID_FEATURES: https://github.com/torvalds/linux/commit/57c22e5f35aa4b9b2fe11f73f3e62bbf9ef36190 But qemu still tries to set it to 0.

2014-06-03kvm: Enable -cpu option to hide KVMAlex Williamson
The latest Nvidia driver (337.88) specifically checks for KVM as the hypervisor and reports Code 43 for the driver in a Windows guest when found. Removing or changing the KVM signature is sufficient for the driver to load and work. This patch adds an option to easily allow the KVM hypervisor signature to be hidden using '-cpu kvm=off'. We continue to expose KVM via the cpuid value by default. The state of this option does not supercede or replace -enable-kvm or the accel=kvm machine option. This only changes the visibility of KVM to the guest and paravirtual features specifically tied to the KVM cpuid.

2014-06-02usb: add usb_pick_speedGerd Hoffmann
We can pick the usb port speed in generic code, by looking at the port and device speed masks and looking for the fastest match. So add a function to do exactly that, and drop the speed setting code from usb_desc_attach as it isn't needed any more. This way we can set the device speed before calling port->ops->attach, which fixes some xhci hotplug issues. https://bugzilla.redhat.com/show_bug.cgi?id=1046873 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2014-06-02Revert "bsd-user: replace fprintf(stderr, ...) with error_report()"Peter Maydell
This reverts commit 1fba509527beb74bdcf50bc07ad3cd8244ad9c61. That commit converted various fprintf(stderr, ...) calls to use error_report(); however none of these bsd-user files include a header which gives a prototype for error_report, so this causes compiler warnings. Since these are just straightforward reporting of command line errors, we should handle these in the obvious way by printing to stderr, as we do for linux-user. There's no need to drag in the error-handling framework for this, especially since user-mode doesn't have the "maybe we need to send this to the monitor" issues system emulation does.

2014-06-02qemu-img: Report error even with --oformat=jsonMax Reitz
img_check() should report that the format of the given image does not support checks even if JSON output is desired. JSON data is output to stdout, as opposed to error messages, which are (in the case of qemu-img) printed to stderr. Therefore, it is easy to distinguish between the two. Also, img_info() does already use error_report() for human-readable messages even though JSON output is desired (through collect_image_info_list()).

2014-05-30vfio: Add guest side IOMMU supportDavid Gibson
This patch uses the new IOMMU notifiers to allow VFIO pass through devices to work with guest side IOMMUs, as long as the host-side VFIO iommu has sufficient capability and granularity to match the guest side. This works by tracking all map and unmap operations on the guest IOMMU using the notifiers, and mirroring them into VFIO. There are a number of FIXMEs, and the scheme involves rather more notifier structures than I'd like, but it should make for a reasonable proof of concept.

2014-05-30vfio: Create VFIOAddressSpace objects as neededDavid Gibson
So far, VFIO has a notion of different logical DMA address spaces, but only ever uses one (system memory). This patch extends this, creating new VFIOAddressSpace objects as necessary, according to the AddressSpace reported by the PCI subsystem for this device's DMAs. This isn't enough yet to support guest side IOMMUs with VFIO, but it does mean we could now support VFIO devices on, for example, a guest side PCI host bridge which maps system memory at somewhere other than 0 in PCI space.

2014-05-30vfio: Introduce VFIO address spacesDavid Gibson
The only model so far supported for VFIO passthrough devices is the model usually used on x86, where all of the guest's RAM is mapped into the (host) IOMMU and there is no IOMMU visible in the guest. This patch begins to relax this model, introducing the notion of a VFIOAddressSpace. This represents a logical DMA address space which will be visible to one or more VFIO devices by appropriate mapping in the (host) IOMMU. Thus the currently global list of containers becomes local to a VFIOAddressSpace, and we verify that we don't attempt to add a VFIO group to multiple address spaces. For now, only one VFIOAddressSpace is created and used, corresponding to main system memory, that will change in future patches.

2014-05-30vfio: Fix 128 bit handlingAlexey Kardashevskiy
Upcoming VFIO on SPAPR PPC64 support will initialize the IOMMU memory region with UINT64_MAX (2^64 bytes) size so int128_get64() will assert. The patch takes care of this check. The existing type1 IOMMU code is not expected to map all 64 bits of RAM so the patch does not touch that part.

2014-05-30memory: Sanity check that no listeners remain on a destroyed AddressSpaceDavid Gibson
At the moment, most AddressSpace objects last as long as the guest system in practice, but that could well change in future. In addition, for VFIO we will be introducing some private per-AdressSpace information, which must be disposed of before the AddressSpace itself is destroyed. To reduce the chances of subtle bugs in this area, this patch adds asssertions to ensure that when an AddressSpace is destroyed, there are no remaining MemoryListeners using that AS as a filter.

2014-05-30vfio-pci: Quirk RTL8168 NICAlex Williamson
This device is ridiculous. It has two MMIO BARs, BAR4 and BAR2. BAR4 hosts the MSI-X table, so oviously it would be too easy to access it directly, instead it creates a window register in BAR2 that, among other things, provides access to the MSI-X table. This means MSI-X doesn't work in the guest because the driver actually manages to program the physical table. When interrupt remapping is present, the device MSI will be blocked. The Linux driver doesn't make use of this window, so apparently it's not required to make use of MSI-X. This quirk makes the device work with the Windows driver that does use this window for MSI-X, but I certainly cannot recommend this device for assignment (the Windows 7 driver also constantly pokes PCI config space).
