This patch adds virtio-pci support for the emulated virtio-input devices. Using them is as simple as adding "-device virtio-tablet-pci" to your command line. If you want add multiple devices but don't want waste a pci slot for each you can compose a multifunction device this way: qemu -device virtio-keyboard-pci,addr=0d.0,multifunction=on \ -device virtio-tablet-pci,addr=0d.1,multifunction=on Signed-off-by: NGerd Hoffmann <kraxel@redhat.com> Reviewed-by: NMichael S.

Initialize the modern bar and the VirtIOPCIRegion fields early, in realize. Also add a size field to VirtIOPCIRegion and variables for pci bars to VirtIOPCIProxy. This allows virtio-pci subclasses to change things before the device_plugged callback applies them. virtio-vga will use that to arrange regions in a way that virtio-vga is compatible to both stdvga (in vga mode) and virtio-gpu-pci (in pci mode).

Currently, during host notifier set. We only add eventfd for legacy bar, this is not correct since: - Non-transitional device does not have legacy bar, so qemu will crash since proxy->bar was not initialized. - Modern device uses modern bar and notify cap to notify the device, we should add eventfd for proxy->notify. So this patch fixes the above two issues by adding eventfd based on whether legacy or modern device were supported. Signed-off-by: NJason Wang <jasowang@redhat.com> Reviewed-by: NMichael S.

virtio 1.0 defines config space as LE, as opposed to pre-1.0 which was native endian. Add API for transports to execute word/dword accesses in little endian format - will be useful for mmio and pci (byte access is also wrapped, for completeness).

Currently we allocate one vhost log per vhost device. This is sub optimal when: - Guest has several device with vhost as backend - Guest has multiqueue devices In the above cases, we can avoid the memory allocation by sharing a single vhost log among all the vhost devices. This is done through: - Introducing a new vhost_log structure with refcnt inside. - Using a global pointer to vhost_log structure that will be used. And introduce helper to get the log with expected log size and helper to - drop the refcnt to the old log. - Each vhost device still keep track of a pointer to the log that was used. With above, if no resize happens, all vhost device will share a single vhost log. During resize, a new vhost_log structure will be allocated and made for the global pointer. And each vhost devices will drop the refcnt to the old log. Tested by doing scp during migration for a 2 queues virtio-net-pci. Cc: Michael S.

This PIIX4 init function has no more reason to receive a pointer to the FwCfg object. Remove the parameter from the prototype, and update callers. As a result, the pc_init1() function no longer needs to save the return value of pc_memory_init() and xen_load_linux(), which makes it more similar to pc_q35_init(). The return type & value of pc_memory_init() and xen_load_linux() are not changed themselves; maybe we'll need their return values sometime later.

The acpi_pm1_cnt_init() core function is responsible for setting up the register block that will ultimately react to S3 and S4 requests (see acpi_pm1_cnt_write()). It makes sense to advertise this configuration to the guest firmware via an easy to parse fw_cfg file (ACPI is too complex for firmware to parse), and indeed PIIX4 does that. However, since acpi_pm1_cnt_init() is not specific to PIIX4, neither should be the fw_cfg file. This patch makes "etc/system-states" appear on all chipsets modified in the previous patch, not just PIIX4 (assuming they have fw_cfg at all).
