Aurelien Jarno b0e3a5fb9f usb: cdc_acm: TX memory and performance improvements ... Currently the cdc_acm implementation pass the data to usb_transfer() by a chunk of IN endpoint MPS. This has 2 drawbacks: - at higher throughput, each transfer needs 2 packets due to the need of an extra ZLP; - a temporary buffer of size USB MPS is needed. This patch improves the memory consumption and performances by passing the ring buffer directly to usb_transfer(). It only has a small performance degradation when the ring buffer wraps and less than a IN endpoint MPS has to be sent. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>		2020-02-19 12:29:50 +02:00
