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>

2014-05-30vfio: 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.

2014-05-30vfio-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).

2014-05-28ssi: Name the CS GPIOPeter Crosthwaite
To get it out of the default GPIO list. This allows child devices to use the un-named GPIO namespace without having to be SSI aware. That is, there is no more need for machines to know about the obscure policy where GPIO 0 is the SSI chip-select and GPIO 1..N are the concrete class GPIOs (defined locally as 0..N-1). This is most notable in stellaris, which uses a device which has both SSI and concrete level GPIOs.

2014-05-28block: Replace in_use with operation blockerFam Zheng
This drops BlockDriverState.in_use with op_blockers: - Call bdrv_op_block_all in place of bdrv_set_in_use(bs, 1). - Call bdrv_op_unblock_all in place of bdrv_set_in_use(bs, 0). - Check bdrv_op_is_blocked() in place of bdrv_in_use(bs). The specific types are used, e.g. in place of starting block backup, bdrv_op_is_blocked(bs, BLOCK_OP_TYPE_BACKUP, ...). There is one exception in block_job_create, where bdrv_op_blocker_is_empty() is used, because we don't know the operation type here. This doesn't matter because in a few commits away we will drop the check and move it to callers that _do_ know the type. - Check bdrv_op_blocker_is_empty() in place of assert(!bs->in_use). Note: there is only bdrv_op_block_all and bdrv_op_unblock_all callers at this moment. So although the checks are specific to op types, this changes can still be seen as identical logic with previously with in_use. The difference is error message are improved because of blocker error info.
