Porting virtio-camera driver for the Android14. This driver is originally designed by Dmitry Osipenko <[email protected]>. Link: https://gitlab.collabora.com/dmitry.osipenko/ linux-kernel-rd/-/tree/virtio-camera Also extend its functions to support multiple video streams for one virtio-camera instance. Per stream per /dev/videoX.

Now the virtio-fs has a bad performance. For improves its performance, we let the virtio-fs driver to support multiple virtqueues and create a separate done-work queue. Keeping these improvements in the virtio-fs driver, and combining them with changes and parameter configurations in the backend, we can see some performance improvements. For example, rand_read performance can be increased from the original 300+MB/s to 400+MB/s. Test done: Configure virtio-fs, then start the VM and you can use virtio-fs normally in the VM Also use the fio tool to see its performance.

For virtio-input devices, writing to config area is defined as selecting config pages. But in virtio over shmem implement, this operation is not supported. The W/A is to update config area upon config selection in BE, and delay a short while after cfg write in FE. This delay does not reduce performance as it only happens during init stage. Test done: Using keyboard/mouse/touchscreen over virtio-input on QNX Tracked-On: OAM-125247 Tracked-On: OAM-127456 Tracked-On: OAM-127455 Tracked-On: OAM-125249 Signed-off-by: Zhao, Shirley <[email protected]> Signed-off-by: Wu Zhou <[email protected]>
