2014-09-08PPC: Cuda: Use cuda timer to expose tbfreq to guestAlexander Graf
Mac OS X calibrates a number of frequencies on bootup based on reading tb values on bootup and comparing them to via cuda timer values. The only variable we can really steer well (thanks to KVM) is the cuda frequency. So let's use that one to fake Mac OS X into believing the bus frequency is tbfreq * 4. That way Mac OS X will automatically calculate the correct timebase frequency. With this patch and the patch set I posted earlier I can successfully run Mac OS X 10.2, 10.3 and 10.4 guests with -M mac99 on TCG and KVM.

2014-08-05vfio: Fix MSI-X vector expansionAlex Williamson
When new MSI-X vectors are enabled we need to disable MSI-X and re-enable it with the correct number of vectors. That means we need to reprogram the eventfd triggers for each vector. Prior to f4d45d47 vector->use tracked whether a vector was masked or unmasked and we could always pick the KVM path when available for unmasked vectors. Now vfio doesn't track mask state itself and vector->use and virq remains configured even for masked vectors. Therefore we need to ask the MSI-X code whether a vector is masked in order to select the correct signaling path. As noted in the comment, MSI relies on hardware to handle masking.

2014-06-30vfio: Make BARs native endianAlexey Kardashevskiy
Slow BAR access path is used when VFIO fails to mmap() BAR. Since this is just a transport between the guest and a device, there is no need to do endianness swapping. This changes BARs to use native endianness. Since non-ROM BARs were doing byte swapping, we need to remove it so does the patch. As the result, this eliminates cancelling byte swaps and there is no change in behavior for non-ROM BARs. ROM BARs were declared little endian too but byte swapping was not implemented for them so they never actually worked on big endian systems as there was no cancelling byte swap. This fixes endiannes for ROM BARs by declaring them native endian and only fixing access sizes as it is done for non-ROM BARs.

2014-06-30vfio-pci: Fix MSI-X masking performanceAlex Williamson
There are still old guests out there that over-exercise MSI-X masking. The current code completely sets-up and tears-down an MSI-X vector on the "use" and "release" callbacks. While this is functional, it can slow an old guest to a crawl. We can easily skip the KVM parts of this so that we keep the MSI route and irqfd setup. We do however need to switch VFIO to trigger a different eventfd while masked. Actually, we have the option of continuing to use -1 to disable the trigger, but by using another EventNotifier we can allow the MSI-X core to emulate pending bits and re-fire the vector once unmasked. MSI code gets updated as well to use the same setup and teardown structures and functions. Prior to this change, an igbvf assigned to a RHEL5 guest gets about 20Mbps and 50 transactions/s with netperf (remote or VF->PF). With this change, we get line rate and 3k transactions/s remote or 2Gbps and 6k+ transactions/s to the PF. No significant change is expected for newer guests with more well behaved MSI-X support.

2014-06-27vfio: Enable for SPAPRAlexey Kardashevskiy
This turns the sPAPR support on and enables VFIO container use in the kernel. This extends vfio_connect_container to support VFIO_SPAPR_TCE_IOMMU type in the host kernel. This registers a memory listener which sPAPR IOMMU will notify when executing H_PUT_TCE/etc DMA calls. The listener then will notify the host kernel about DMA map/unmap operation via VFIO_IOMMU_MAP_DMA/ VFIO_IOMMU_UNMAP_DMA ioctls. This executes VFIO_IOMMU_ENABLE ioctl to make sure that the IOMMU is free of mappings and can be exclusively given to the user. At the moment SPAPR is the only platform requiring this call to be implemented. Note that the host kernel function implementing VFIO_IOMMU_DISABLE is called automatically when container's fd is closed so there is no need to call it explicitly from QEMU. We may need to call VFIO_IOMMU_DISABLE explicitly in the future for some sort of dynamic reconfiguration (PCI hotplug or dynamic IOMMU group management).

The first example of it will be reading a DMA window start from the host. This adds a helper which passes an ioctl request to the container's fd. The helper will check if @req is known. For this, stub is added. This return -1 on any requests for now.

2014-06-16macio ide: Do remainder access asynchronouslyAlexander Graf
The macio IDE controller has some pretty nasty magic in its implementation to allow for unaligned sector accesses. We used to handle these accesses synchronously inside the IO callback handler. However, the block infrastructure changed below our feet and now it's impossible to call a synchronous block read/write from the aio callback handler of a previous block access. Work around that limitation by making the unaligned handling bits also go through our asynchronous handler. This fixes booting Mac OS X for me.

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-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).

Using error_is_set(ERRP) to find out whether a function failed is either wrong, fragile, or unnecessarily opaque. It's wrong when ERRP may be null, because errors go undetected when it is. It's fragile when proving ERRP non-null involves a non-local argument. Else, it's unnecessarily opaque (see commit 84d18f0). I guess the error_is_set(errp) in the ObjectProperty set() methods are merely fragile right now, because I can't find a call chain that passes a null errp argument.

Change the DB_PRINT macro over to a regular if() rather than conditional compilation to give constant compile testing of formats.

2014-04-17misc: zynq-slcr: RewritePeter Crosthwaite
Near total rewrite of this device model. It is stylistically obsolete, has numerous coverity fails and is not up to date with latest Xilinx documentation. Fix. The registers are flattened into a single array. This greatly simplifies the MMIO accessor functions. We take the oppurtunity to update the register Macro definitions to match the latest TRM. Xilinx has de-documented some regs hence there are some straight deletions. We only do this however in the case or a stock read-as-written reset-zero register. Non-zero resets are always preserved. New register definitions are added as needed. This all comes with a VMSD version break as the union layout from before was a bit strange and we are better off without it.
