2010-04-14vhost.c: include <linux/vhost.h> lastMarcelo Tosatti
So the userspace headers define KERNEL_STRICT_NAMES and there's no conflict on type definition for older kernels. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Acked-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-04-13vhost-net: disable mergeable buffersMichael S. Tsirkin
vhost in current kernels doesn't support mergeable buffers. Disable this feature if vhost is enabled, until such support is implemented. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-04-13vhost: fix features ackDavid L Stevens
vhost driver in qemu didn't ack features, and this happens to work because we don't really require any features. However, it's better not to rely on this. This patch passes features to vhost as guest acks them. Signed-off-by: David L Stevens <dlstevens@us.ibm.com> Signed-off-by: Michael S.

2010-04-13sh_pci: fix memory and I/O accessAurelien Jarno
Since commit 8da3ff180974732fc4272cb4433fef85c1822961 ("MMIO callback interface changes"), the addresses passed to the I/O functions are an offset to the start of the area. As a consequence, there is no need to correct the address using the value of IOBR. This make possible the use of the default MMIO functions. Moreover the addresses are now remaped when the value if IOBR change. The memory area corresponds to the devices behing the PCI bus, it should not be mapped by the PCI controller. Remove the corresponding code. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-04-13r2d: always enable IDE and flashAurelien Jarno
IDE and flash are part of the R2D board, and can't be removed. Emulate them even if there is no hard-drive plugged to the IDE or if the flash content is empty.

2010-04-09Implement virtio resetAlexander Graf
The guest may issue a RESET command for virtio. So far we didn't bother to implement it, but with my new bootloader we actually need it for Linux to get back to a safe state. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-04-09move targphys.h and hw/poison.h inclusion to cpu-common.hPaolo Bonzini
With more files from outside the hw/ directory being placed into libhw, avoid the need to include hw/hw.h for the sake of targ_phys_addr_t. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

Some drivers seems to access the reserved register in bank 0 so allow and ignore these accesses. Signed-off-by: Lars Munch <lars@segv.dk> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-04-08smc91c111: mask register offsetLars Munch
this fixes the smc91c111 emulation which has been broken for gumstix and mainstone and maybe others since the "MMIO callback interface changes" 8da3ff180974732fc4272cb4433fef85c1822961 was commited. Signed-off-by: Lars Munch <lars@segv.dk> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-04-08update bochs vbe interfaceGerd Hoffmann
The bochs vbe interface got a new register a while back, which specifies the linear framebuffer size in 64k units. This patch adds support for the new register to qemu.

2010-04-05ARMv7-M reset fixesPaul Brook
Move ARMv7-M PC/SP initialization to the CPU reset routine. Add a board reset routine to call this. Also load values directly from ROM as images have not been copied yet. Avoid clearing the NVIC pointer on cpu reset. Signed-off-by: Paul Brook <paul@codesourcery.com>

This reverts commit f1698408f1dcb7548a21828a0b1e2b530fae3af3. PCI is always little-endian. Having a user-visible "be" property is just plain wrong.

2010-04-03sparc32: improve timer implementationBlue Swirl
Timer with zero period (free-run) will never match. Timer counting starts with tick value of 0x200, not from 0, so the period must calculated from one tick less than the limit. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2010-04-01virtio-net: vhost net supportMichael S. Tsirkin
This connects virtio-net to vhost net backend. The code is structured in a way analogous to what we have with vnet header capability in tap. We start/stop backend on driver start/stop as well as on save and vm start (for migration). Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-04-01vhost: vhost net supportMichael S. Tsirkin
This adds vhost net device support in qemu. Will be tied to tap device and virtio by following patches. Raw backend is currently missing, will be worked on/submitted separately. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-04-01virtio-pci: fill in notifier supportMichael S. Tsirkin
Support host/guest notifiers in virtio-pci. The last one only with kvm, that's okay because vhost relies on kvm anyway. Note on kvm usage: kvm ioeventfd API is implemented on non-kvm systems as well, this is the reason we don't need if (kvm_enabled()) around it. Signed-off-by: Michael S.

2010-04-01virtio: add set_status callbackMichael S. Tsirkin
vhost net backend needs to be notified when frontend status changes. Add a callback, similar to set_features. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-04-01virtio: notifier support + APIs for queue fieldsMichael S. Tsirkin
vhost needs physical addresses for ring and other queue fields, so add APIs for these. In particular, add binding API to set host/guest notifiers. Will be used by vhost. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-04-01notifier: event notifier implementationMichael S. Tsirkin
event notifiers are slightly generalized eventfd descriptors. Current implementation depends on eventfd because vhost is the only user, and vhost depends on eventfd anyway, but a stub is provided for non-eventfd case. We'll be able to further generalize this when another user comes along and we see how to best do this. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-03-31Don't check for bus master for old guestsAlexander Graf
Older Linux guests don't activate the bus master enable bit. So for those we can just try to be clever and track if they set the DEVICE_OK bit even though bus mastering is still disabled. Under that condition we can disable the windows safety check. With that logic in place both guests should work just fine. Without PCI hotplug breaks virtio-net in Linux < 2.6.34 guests.

2010-03-31usb: class specific interface requestsMax Reitz
Mass Storage Reset and Get Max LUN are class specific requests, but they were not marked as such in hw/usb-msd.c, moved therefore ClassInterfaceRequest and ClassInterfaceOutRequest from hw/usb-net.c to hw/usb.h. Furthermore there was a problem in hw/usb-ohci.c when using DEBUG concerning systems where size_t is a 32 bit integer (printf resulted in a segmentation fault).

2010-03-27balloon: Fix overflow when reporting actual memory sizeAdam Litke
Beginning with its introduction, the virtio balloon has had an overflow error that causes 'info balloon' to misreport the actual memory size when the balloon itself becomes larger than 4G.
