Hi All,
I am trying to add the throttle to the virtio-9p devices using the throttle APIs that are already exists in the qemu.
I need help to understand the device model and where to add the throttling. I am digging through the code since a week or so but failed to understand how to tell the driver (virtio-9p) about the throttle enablement for this specific fs device.
I am planning to enable and configure the throttle for that specific device at
int qemu_fsdev_add(QemuOpts *opts) in qemu-fsdev.c file.
After that I would like to just add throttle facility to just virtio-9p-local.c (i.e read/wrote calls).
Though there are other drivers, I just want to add to this specific driver as of now.
This is where I am missing the link like how to get to know the device configuration for this specific device throttle enabled or not and carry out the operations accordingly.
Please help me to understand.
Regards,
Pradeep
