2022-07-20vdpa: manual forward CVQ buffersEugenio Pérez
Do a simple forwarding of CVQ buffers, the same work SVQ could do but through callbacks. No functional change intended. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-07-20vhost-net-vdpa: add stubs for when no virtio-net device is presentEugenio Pérez
net/vhost-vdpa.c will need functions that are declared in vhost-shadow-virtqueue.c, that needs functions of virtio-net.c. Copy the vhost-vdpa-stub.c code so only the constructor net_init_vhost_vdpa needs to be defined. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2022-07-20vdpa: Export vhost_vdpa_dma_map and unmap callsEugenio Pérez
Shadow CVQ will copy buffers on qemu VA, so we avoid TOCTOU attacks from the guest that could set a different state in qemu device model and vdpa device. To do so, it needs to be able to map these new buffers to the device. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Reviewed-by: Michael S.

2022-07-20vhost: Add svq avail_handler callbackEugenio Pérez
This allows external handlers to be aware of new buffers that the guest places in the virtqueue. When this callback is defined the ownership of the guest's virtqueue element is transferred to the callback. This means that if the user wants to forward the descriptor it needs to manually inject it. The callback is also free to process the command by itself and use the element with svq_push.

2022-07-20vhost: Decouple vhost_svq_add from VirtQueueElementEugenio Pérez
VirtQueueElement comes from the guest, but we're heading SVQ to be able to modify the element presented to the device without the guest's knowledge. To do so, make SVQ accept sg buffers directly, instead of using VirtQueueElement. Add vhost_svq_add_element to maintain element convenience.

2022-07-20vdpa: Avoid compiler to squash reads to used idxEugenio Pérez
In the next patch we will allow busypolling of this value. The compiler have a running path where shadow_used_idx, last_used_idx, and vring used idx are not modified within the same thread busypolling. This was not an issue before since we always cleared device event notifier before checking it, and that could act as memory barrier. However, the busypoll needs something similar to kernel READ_ONCE.

2022-07-18lasips2: switch to using port-based IRQsMark Cave-Ayland
Now we can implement port-based IRQs by wiring the PS2 device IRQs to the LASI2Port named input gpios rather than directly to the LASIPS2 device, and generate the LASIPS2 output IRQ from the int_status bitmap representing the individual port IRQs instead of the birq boolean. This enables us to remove the separate PS2 keyboard and PS2 mouse named input gpios from the LASIPS2 device and simplify the register implementation to drive the port IRQ using qemu_set_irq() rather than accessing the LASIPS2 device IRQs directly. As a consequence the IRQ level logic in lasips2_set_irq() can also be simplified accordingly. For now this patch ignores adding the int_status bitmap and simply drops the birq boolean from the vmstate_lasips2 VMStateDescription. This is because the migration stream is already missing some required LASIPS2 fields, and as this series already introduces a migration break for the lasips2 device it is easiest to fix this in a follow-up patch.
