VirtIO Bluetooth Driver On The Way To The Linux Kernel
Queued up within Bluetooth-Next as of yesterday and in advance of the upcoming Linux 5.13 merge window is a VirtIO transport driver. This "virtio_bt" driver allows for Bluetooth HCI transport over VirtIO. This VirtIO addition was led by Intel engineers.
So for those looking to see better support for Bluetooth devices directly within virtualized environments on Linux, while arguably somewhat of a niche case, this driver has been queued in Bluetooth-Next.
