2012-11-14qemu-iotests: qcow2: Test growing large refcount tableKevin Wolf
Actually writing all the content with 512 byte sector size would take forever, therefore build the image file with a Python script and use qemu-io for the last write that actually triggers the refcount table growth. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2012-11-14qcow2: Fix refcount table size calculationKevin Wolf
A missing factor for the refcount table entry size in the calculation could mean that too little memory was allocated for the in-memory representation of the table, resulting in a buffer overflow.

2012-11-13vfio-pci: Use common msi_get_messageAlex Williamson
We can get rid of our local version now that a helper exists. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
2012-11-13vfio-pci: Add KVM INTx accelerationAlex Williamson
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.

2012-11-13nbd: fixes to read-only handlingPaolo Bonzini
We do not need BLKROSET if the kernel supports setting flags. Also, always do BLKROSET even for a read-write export, otherwise the read-only state remains "sticky" after the invocation of "qemu-nbd -r". Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-11-12aio: fix aio_ctx_prepare with idle bottom halvesPaolo Bonzini
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 Bonzini
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 Maydell
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 Bonzini
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 Bonzini
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>
2012-11-12nbd: force read-only export for read-only devicesPaolo Bonzini

2012-11-10tests/tcg: new test for i386 FPREM and FPREM1Catalin Patulea
This is setting the stage for a cleanup of FPREM and FPREM1 helpers while being sure that they behave same as bare metal. The test constructs operands using combinations of corner cases for the floating-point bitfields and prints operands, result and FPU status word for FPREM and FPREM1. The outputs can then be compared between bare metal and QEMU. The 'run-test-i386-fprem' make target does just that.
