Queue event polling work with 0 delay in case there are pending transfers queued up. This is part 2 of a 3 part series that roughly triples dbc performace when using adb push and pull over dbc. Max/min push rate after patches is 210/118 MB/s, pull rate 171/133 MB/s, tested with large files (300MB-9GB) by Łukasz Bartosik First performance improvement patch was commit 31128e7492dc ("xhci: dbc: add dbgtty request to end of list once it completes") Cc: Łukasz Bartosik <ukaszb@chromium.org> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> --- drivers/usb/host/xhci-dbgcap.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
