USB_ALLOC_STREAMS(9) Host Controller APIs USB_ALLOC_STREAMS(9)NAMEusb_alloc_streams - allocate bulk endpoint stream IDs.
SYNOPSIS
int usb_alloc_streams(struct usb_interface * interface,
struct usb_host_endpoint ** eps,
unsigned int num_eps, unsigned int num_streams,
gfp_t mem_flags);
ARGUMENTS
interface
alternate setting that includes all endpoints.
eps
array of endpoints that need streams.
num_eps
number of endpoints in the array.
num_streams
number of streams to allocate.
mem_flags
flags hcd should use to allocate memory.
DESCRIPTION
Sets up a group of bulk endpoints to have num_streams stream IDs
available. Drivers may queue multiple transfers to different stream
IDs, which may complete in a different order than they were queued.
