2012-11-16virtio-rng-pci: create a default backend if none existsAnthony Liguori2-0/+15
This allows you to specify: $ qemu -device virtio-rng-pci And things will Just Work with a reasonable default. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-11-16virtio-rng: add rate limiting supportAnthony Liguori3-8/+64
This adds parameters to virtio-rng-pci to allow rate limiting the entropy a guest receives. An example command line: $ qemu -device virtio-rng-pci,max-bytes=1024,period=1000 Would limit entropy collection to 1Kb/s. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-11-16virtio-rng: hardware random number generator deviceAmit Shah9-0/+341
The Linux kernel already has a virtio-rng driver, this is the device implementation. When the guest asks for entropy from the virtio hwrng, it puts a buffer in the vq. We then put entropy into that buffer, and push it back to the guest.

2012-11-16rng-egd: introduce EGD compliant RNG backendAnthony Liguori2-1/+216
This backend talks EGD to a CharDriverState. A typical way to invoke this would be: qemu -chardev socket,host=localhost,port=1024,id=chr0 \ -object rng-egd,chardev=chr0,id=egd0 \ -device virtio-rng-pci,rng=egd0 Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-11-16rng-random: add an RNG backend that uses /dev/random (v3)Anthony Liguori3-1/+184
The filename can be overridden but it expects a non-blocking source of entropy. A typical invocation would be: qemu -object rng-random,id=rng0 -device virtio-rng-pci,rng=rng0 This can also be used with /dev/urandom by using the command line: qemu -object rng-random,filename=/dev/urandom,id=rng0 \ -device virtio-rng-pci,rng=rng0 Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> --- v1 -> v2 - merged header split patch into this one v2 -> v3 - bug fix in rng-random (Paolo)

2012-11-16vl: add -object option to create QOM objects from the command lineAnthony Liguori3-0/+74
This will create a new QOM object in the '/objects' path. Note that properties are set in order which allows for simple objects to be initialized entirely with this option and then realized. This option is roughly equivalent to -device but for things that are not devices. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-11-15mips/malta: fix CBUS UART interrupt pinAurelien Jarno1-1/+2
According to the MIPS Malta Developement Platform User's Manual, the i8259 interrupt controller is supposed to be connected to the hardware IRQ0, and the CBUS UART to the hardware interrupt 2. In QEMU they are both connected to hardware interrupt 0, the CBUS UART interrupt being wrong. This patch fixes that. It should be noted that the irq array in QEMU includes the software interrupts, hence env->irq[2] is the first hardware interrupt.

2012-11-13vfio-pci: Add KVM INTx accelerationAlex Williamson1-0/+186
This makes use of the new level irqfd support enabling bypass of qemu userspace both on INTx injection and unmask. This significantly boosts the performance of devices making use of legacy interrupts (ex. ~60% better netperf TCP_RR scores for an e1000e assigned to a Linux guest and booted with pci=nomsi). This also avoids flipping mmaps on and off to simulate EOIs, so greatly improves performance of device access in addition to interrupt latency.

2012-11-12aio: fix aio_ctx_prepare with idle bottom halvesPaolo Bonzini1-4/+2
Commit ed2aec4867f0d5f5de496bb765347b5d0cfe113d changed the return value of aio_ctx_prepare from false to true when only idle bottom halves are available. This broke PC old-style DMA, which uses them. Fix this by making aio_ctx_prepare return true only when non-idle bottom halves are scheduled to run.

2012-11-12virtio-scsi: use dma_context_memoryPaolo Bonzini1-1/+1
Until address_space_rw was introduced, NULL was accepted as a placeholder for DMA with no IOMMU (to address_space_memory). This does not work anymore, and dma_context_memory needs to be specified explicitly. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-11-12dma: Define dma_context_memory and use in sysbus-ohciPeter Maydell3-1/+11
Define a new global dma_context_memory which is a DMAContext corresponding to the global address_space_memory AddressSpace. This can be used by sysbus peripherals like sysbus-ohci which need to do DMA. In particular, use it in the sysbus-ohci device, which fixes a segfault when attempting to use that device.

2012-11-12scsi: do not return short responses for emulated commandsPaolo Bonzini1-16/+18
The inquiry command, for the case of VPD=1, was returning short responses; the number of returned bytes was just the number of bytes in the request, without padding to the specified allocation length with zero bytes. This is usually harmless, but it is a violation of the SCSI specification. To fix this, always pad with zero bytes to r->cmd.xfer in scsi_disk_emulate_command, and return at most r->buflen bytes (the size of the buffer for command data) rather than at most buflen bytes (the number of bytes that was filled in). Before this patch, "strace sg_inq -p0x83 /dev/sda" would report a non-zero resid value. After this patch, it reports resid=0. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-11-12nbd: disallow nbd-server-add before nbd-server-startPaolo Bonzini1-0/+5
It works nicely with the QMP commands, but it adds useless complication with HMP. In particular, see the following: (qemu) nbd_server_add -w scsi0-hd0 (qemu) nbd_server_start -a localhost:10809 NBD server already exporting device scsi0-hd0 Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
