* ftgmac100: fix multicast hash routineCédric Le Goater2018-06-081-2/+2

* ftgmac100: add IEEE 802.1Q VLAN supportCédric Le Goater2018-06-081-1/+30
| | | | | | | | | | | | | | | The ftgmac100 NIC supports VLAN tag insertion and the MAC engine also has a control to remove VLAN tags from received packets. The VLAN control bits and VLAN tag information are contained in the second word of the transmit and receive descriptors. The Insert VLAN bit and the VLAN Tag available bit are only valid in the first segment of the packet.

* arm_gicv3_kvm: kvm_dist_get/put: skip the registers banked by GICRShannon Zhao2018-06-082-0/+117
| | | | | | | | | | | | | | | | | | | | While we skip the GIC_INTERNAL irqs, we don't change the register offset accordingly. This will overlap the GICR registers value and leave the last GIC_INTERNAL irq's registers out of update. Fix this by skipping the registers banked by GICR. Also for migration compatibility if the migration source (old version qemu) doesn't send gicd_no_migration_shift_bug = 1 to destination, then we shift the data of PPI to get the right data for SPI.

| | | | | | | | | | | | The 9p-local code previously relied on P9_DOTL_AT_REMOVEDIR and AT_REMOVEDIR having the same numerical value and deferred any errorchecking to the syscall itself.

* vfio/quirks: Enable ioeventfd quirks to be handled by vfio directlyAlex Williamson2018-06-054-8/+51
| | | | | | | | | | | | | With vfio ioeventfd support, we can program vfio-pci to perform a specified BAR write when an eventfd is triggered. This allows the KVM ioeventfd to be wired directly to vfio-pci, entirely avoiding userspace handling for these events. On the same micro-benchmark where the ioeventfd got us to almost 90% of performance versus disabling the GeForce quirks, this gets us to within 95%.

* vfio/quirks: ioeventfd quirk accelerationAlex Williamson2018-06-054-2/+183
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NVIDIA BAR0 quirks virtualize the PCI config space mirrors found in device MMIO space. Normally PCI config space is considered a slow path and further optimization is unnecessary, however NVIDIA uses a register here to enable the MSI interrupt to re-trigger. Exiting to QEMU for this MSI-ACK handling can therefore rate limit our interrupt handling. Fortunately the MSI-ACK write is easily detected since the quirk MemoryRegion otherwise has very few accesses, so simply looking for consecutive writes with the same data is sufficient, in this case 10 consecutive writes with the same data and size is arbitrarily chosen. We configure the KVM ioeventfd with data match, so there's no risk of triggering for the wrong data or size, but we do risk that pathological driver behavior might consume all of QEMU's file descriptors, so we cap ourselves to 10 ioeventfds for this purpose. In support of the above, generic ioeventfd infrastructure is added for vfio quirks. This automatically initializes an ioeventfd list per quirk, disables and frees ioeventfds on exit, and allows ioeventfds marked as dynamic to be dropped on device reset. The rationale for this latter feature is that useful ioeventfds may depend on specific driver behavior and since we necessarily place a cap on our use of ioeventfds, a machine reset is a reasonable point at which to assume a new driver and re-profile.

| * | vhost-user: introduce shared vhost-user stateTiwei Bie2018-05-245-12/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When multi queue is enabled e.g. for a virtio-net device, each queue pair will have a vhost_dev, and the only thing shared between vhost devs currently is the chardev. This patch introduces a vhost-user state structure which will be shared by all vhost devs of the same virtio device. Signed-off-by: Tiwei Bie <tiwei.bie@intel.com> Signed-off-by: Michael S.
