2014-02-26vfio: blacklist loading of unstable romsBandan Das
Certain cards such as the Broadcom BCM57810 have rom quirks that exhibit unstable system behavior duing device assignment. In the particular case of 57810, rom execution hangs and if a FLR follows, the device becomes inoperable until a power cycle. This change blacklists loading of rom for such cards unless the user specifies a romfile or rombar=1 on the cmd line Signed-off-by: Bandan Das <bsd@redhat.com> Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

readlink() returns the number of bytes written to the buffer, and it doesn't write a terminating null byte. vfio_init() writes it itself. Overruns the buffer when readlink() filled it completely.

2014-02-26target-arm: Store AIF bits in env->pstate for AArch32Peter Maydell
To avoid complication in code that otherwise would not need to care about whether EL1 is AArch32 or AArch64, we should store the interrupt mask bits (CPSR.AIF in AArch32 and PSTATE.DAIF in AArch64) in one place consistently regardless of EL1's mode. Since AArch64 has an extra enable bit (D for debug exceptions) which isn't visible in AArch32, this means we need to keep the enables in env->pstate. (This is also consistent with the general approach we're taking that we handle 32 bit CPUs as being like AArch64/ARMv8 CPUs but which only run in 32 bit mode.)

2014-02-26hw: arm_gic_kvm: Add KVM VGIC save/restore logicChristoffer Dall
Save and restore the ARM KVM VGIC state from the kernel. We rely on QEMU to marshal the GICState data structure and therefore simply synchronize the kernel state with the QEMU emulated state in both directions. We take some care on the restore path to check the VGIC has been configured with enough IRQs and CPU interfaces that we can properly restore the state, and for separate set/clear registers we first fully clear the registers and then set the required bits.

2014-02-26arm: vgic device control api supportChristoffer Dall
Support creating the ARM vgic device through the device control API and setting the base address for the distributor and cpu interfaces in KVM VMs using this API. Because the older KVM_CREATE_IRQCHIP interface needs the irq chip to be created prior to creating the VCPUs, we first test if we can use the device control API in kvm_arch_irqchip_create (using the test flag from the device control API). If we cannot, it means we have to fall back to KVM_CREATE_IRQCHIP and use the older ioctl at this point in time. If however, we can use the device control API, we don't do anything and wait until the arm_gic_kvm driver initializes and let that use the device control API.

2014-02-25net: remove implicit peer from offload APIStefan Hajnoczi
The virtio_net offload APIs are used on the NIC's peer (i.e. the tap device). The API was defined to implicitly use nc->peer, saving the caller the trouble. This wasn't ideal because: 1. There are callers who have the peer but not the NIC. Currently they are forced to bypass the API and access peer->info->... directly. 2. The rest of the net.h API uses nc, not nc->peer, so it is inconsistent. This patch pushes nc->peer back up to callers. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2014-02-20xen_disk: fix io accountingOlaf Hering
