Struct VirtqAvail 

Source 
#[repr(C)]
pub struct VirtqAvail {
    pub flags: u16,
    pub idx: u16,
    pub ring: [u16; 256],
}
Expand description

Available ring: driver writes descriptor chain heads here for the device to consume.

Fields§

§flags: u16

Flags (e.g., VIRTQ_AVAIL_F_NO_INTERRUPT to suppress used-buffer notifications)

§idx: u16

Index of the next entry the driver will write to in ring[]

§ring: [u16; 256]

Ring of descriptor chain head indices
