Yeah, I like it! :)

Yup, sounds right.

vDPA device currently relays the eventfd via vhost worker. This is
inefficient due the latency of wakeup and scheduling, so this patch
tries to introduce a use_worker attribute for the vhost device. When
use_worker is not set with vhost_dev_init(), vhost won't try to
allocate a worker thread and th
For the device that doesn't use vhost worker and use_mm(), mmget() is
too heavy weight and it may brings troubles for implementing mmap()
support for vDPA device.
This is because, an reference to the address space was held via
mm_get() in vhost_dev_set_owner() and an reference to the file was
held
Hi all:
This series introduce basic functionality of doorbell mapping support
for vhost-vDPA. Userspace program may use mmap() to map a the doorbell

Currently the doorbell is relayed via eventfd which may have
significant overhead because of the cost of vmexits or syscall. This
patch introduces mmap() based doorbell mapping which can eliminate the
overhead caused by vmexit or syscall.
To ease the userspace modeling of the doorbell layout (usua

This patch introduces a new method in the vdpa_config_ops which
reports the physical address and the size of the doorbell for a
specific virtqueue.
This will be used by the future patches that maps doorbell to
userspace.

This patch adds support for reporting doorbell location in vp_vdpa
driver. The doorbell mapping could be then enabled by e.g launching
qemu's virtio-net-pci device with page-per-vq enabled.

This patch introduce a vDPA driver for virtio-pci device. It bridges
the virtio-pci control command to the vDPA bus. This will be used for
developing new features for both software vDPA framework and hardware
vDPA feature.
Compared to vdpa_sim, it has several advantages:
- it's a real device driv

A node that has the MRA role, it can behave as MRM or MRC.
Initially it starts as MRM and sends MRP_Test frames on both ring ports.
If it detects that there are MRP_Test send by another MRM, then it
checks if these frames have a lower priority than itself. In this case
it would send MRP_Nack frame
