2013-11-21vfio-pci: Fix multifunction=onAlex Williamson1-0/+7
When an assigned device is initialized it copies the device config space into the emulated config space. Unfortunately multifunction is setup prior to the device initfn and gets clobbered. We need to restore it just like pci-assign does. Cc: qemu-stable@nongnu.org Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-11-21pc: get rid of builtin pvpanic for "-M pc-1.5"Paolo Bonzini1-5/+0
This causes two slight backwards-incompatibilities between "-M pc-1.5" and 1.5's "-M pc": (1) a fw_cfg file is removed with this patch. This is only a problem if migration stops the virtual machine exactly during fw_cfg enumeration. (2) after migration, a VM created without an explicit "-device pvpanic" will stop reporting panics to management. The first problem only occurs if migration is done at a very, very early point (and I'm not sure it can happen in practice for reasonable-size VMs, since it will likely take more time to send the RAM to destination, than it will take for BIOS to scan fw_cfg). The second problem only occurs if the guest panics _and_ has a guest driver _and_ management knows to look at the crash event, so it is mostly theoretical at this point in time. Thus keep the code simple, and pretend it was never broken. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2013-10-31integrator: fix Linux boot failure by emulating dbg regionAlex Bennée2-0/+100
Commit 9b8c69243 (since reverted) broke the ability to boot the kernel as the value returned by unassigned_mem_read returned non-zero and left the kernel looping forever waiting for it to change (see integrator_led_set in the kernel code). Relying on a varying implementation detail is incorrect anyway so this introduces a basic stub of a memory region for the debug/LED section on the integrator board.

2013-10-02vfio-pci: Implement PCI hot resetAlex Williamson1-38/+300
Now that VFIO has a PCI hot reset interface, take advantage of it. There are two modes that we need to consider. The first is when only one device within the set of devices affected is actually assigned to the guest. In this case the other devices are are just held by VFIO for isolation and we can pretend they're not there, doing an entire bus reset whenever the device reset callback is triggered. Supporting this case separately allows us to do the best reset we can do of the device even if the device is hotplugged. The second mode is when multiple affected devices are all exposed to the guest. In this case we can only do a hot reset when the entire system is being reset. However, this also allows us to track which individual devices are affected by a reset and only do them once. We split our reset function into pre- and post-reset helper functions prioritize the types of device resets available to us, and create separate _one vs _multi reset interfaces to handle the distinct cases above.

2013-10-02vfio-pci: Lazy PCI option ROM loadingAlex Williamson1-62/+122
During vfio-pci initfn, the device is not always in a state where the option ROM can be read. In the case of graphics cards, there's often no per function reset, which means we have host driver state affecting whether the option ROM is usable. Ideally we want to move reading the option ROM past any co-assigned device resets to the point where the guest first tries to read the ROM itself. To accomplish this, we switch the memory region for the option rom to an I/O region rather than a memory mapped region. This has the side benefit that we don't waste KVM memory slots for a BAR where we don't care about performance. This also allows us to delay loading the ROM from the device until the first read by the guest. We then use the PCI config space size of the ROM BAR when setting up the BAR through QEMU PCI. Another benefit of this approach is that previously when a user set the ROM to a file using the romfile= option, we still probed VFIO for the parameters of the ROM, which can result in dmesg errors about an invalid ROM. We now only probe VFIO to get the ROM contents if the guest actually tries to read the ROM. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
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>
