2013-10-02vfio-pci: Test device reset capabilitiesAlex Williamson1-0/+46
Not all resets are created equal. PM reset is not very reliable, especially for GPUs, so we might want to opt for a bus reset if a standard reset will only do a D3hot->D0 transition. We can also use this to tell if the standard reset will do a bus reset (if neither has_pm_reset or has_flr is probed, but the device still supports reset).

2013-10-02vfio-pci: Add support for MSI affinityAlex Williamson1-7/+40
When MSI is accelerated through KVM the vectors are only programmed when the guest first enables MSI support.  Subsequent writes to the vector address or data fields are ignored.  Unfortunately that means we're ignore updates done to adjust SMP affinity of the vectors. MSI SMP affinity already works in non-KVM mode because the address and data fields are read from their backing store on each interrupt. This patch stores the MSIMessage programmed into KVM so that we can determine when changes are made and update the routes. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

2013-08-09kvm: add KVM_IRQFD_FLAG_RESAMPLE supportVincenzo Maffione1-2/+2
Added an EventNotifier* parameter to kvm-all.c:kvm_irqchip_add_irqfd_notifier(), in order to give KVM another eventfd to be used as "resamplefd". See the documentation in the linux kernel sources in Documentation/virtual/kvm/api.txt (section 4.75) for more details. When the added parameter is passed NULL, the behaviour of the function is unchanged with respect to the previous versions.

2013-07-15vfio: QEMU-AER: Qemu changes to support AER for VFIO-PCI devicesVijay Mohan Pandarathil1-0/+125
Add support for error containment when a VFIO device assigned to a KVM guest encounters an error. This is for PCIe devices/drivers that support AER functionality. When the host OS is notified of an error in a device either through the firmware first approach or through an interrupt handled by the AER root port driver, the error handler registered by the vfio-pci driver gets invoked. The qemu process is signaled through an eventfd registered per VFIO device by the qemu process. In the eventfd handler, qemu decides on what action to take. In this implementation, guest is brought down to contain the error. The kernel patches for the above functionality has been already accepted. This is a refresh of the QEMU patch which was reviewed earlier. http://marc.info/?l=linux-kernel&m=136281557608087&w=2 This patch has the same contents and has been built after refreshing to latest upstream and after the linux headers have been updated in qemu. - Create eventfd per vfio device assigned to a guest and register an event handler - This fd is passed to the vfio_pci driver through the SET_IRQ ioctl - When the device encounters an error, the eventfd is signalled and the qemu eventfd handler gets invoked. - In the handler decide what action to take. Current action taken is to stop the guest. Signed-off-by: Vijay Mohan Pandarathil <vijaymohan.pandarathil@hp.com> Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2013-07-15vfio-pci: VGA quirk updateAlex Williamson1-336/+321
Turns out all the suspicions for AMD devices were correct, everywhere we read a BAR address that the address matches the config space offset, there's full access to PCI config space. Attempt to generalize some helpers to allow quirks to easily be added for mirrors and windows. Also fill in complete config space for AMD. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2013-07-11PPC: Add timer handler for newworld mac-ioAlexander Graf1-0/+33
Mac OS X accesses fancy timer registers inside of the mac-io on bootup. These really should be ticking at the mac-io bus frequency, but I don't see anyone upset when we just make them as fast as we want to. With this patch on top of my previous patch queue and latest OpenBIOS I am able to boot Mac OS X 10.4 with -M mac99. Signed-off-by: Alexander Graf <agraf@suse.de>
2013-07-11PPC: dbdma: Move processing to ioAlexander Graf1-4/+6
Soon we will introduce intermediate processing pauses which will allow the bottom half to restart a DMA request that couldn't be fulfilled yet. For that to work, move the processing variable into the io struct which is what DMA providers work with. While touching it, also change it into a bool Signed-off-by: Alexander Graf <agraf@suse.de>
2013-07-11PPC: dbdma: Move static bh variable to device structAlexander Graf1-9/+15

2013-07-11PPC: dbdma: Introduce kick functionAlexander Graf1-0/+5

2013-07-11PPC: dbdma: Allow new commands in RUN stateAlexander Graf1-3/+3
The DBDMA controller can not change its command stream while it's actively streaming data, true. But the fact that it's in RUN state doesn't actually indicate anything. It could just as well be in WAIT while in RUN. And then it's legal to change commands. This fixes a real world issue I've encountered with Mac OS X. Signed-off-by: Alexander Graf <agraf@suse.de>
