CSP bit of TRB Control is useful for protocols such CDC EEM/ECM/NCM where we're transferring in blocks of MTU-sized requests (usually MTU is 1500 bytes). We know we will always have a short packet after two (for HS) wMaxPacketSize packets and, usually, we will have a long(-ish) queue of requests (for our g_ether gadget, we have at least 10 requests). Instead of always stopping the queue processing to interrupt, giveback and restart, let's tell dwc3 to interrupt but continue processing following request if we have anything already pending in the queue. This gave me a considerable improvement of 40% on my test setup. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com> |
