Not much. There are now just four "Mode Mismatch Interrupt" instead of five. I did a short 400MiB read speed test from a fast usb stick. The dwc2 driver (with the param_ltq values) is faster than ifxhcd. ifxhcd: real 0m 23.26s user 0m 0.01s sys 0m 15.18s dwc2: real 0m 16.31s user 0m 0.00s sys 0m 8.38s Regards, Christian > [4] > <https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/usb/dwc2?id=2938fc63e0c26bf694436ac81bc776c8b7eced0c> > [5] > <https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/usb/dwc2?id=fef6bc37dbafe0d6d71c808c8867a8c5ab4b9816> > [6] > <https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/usb/dwc2?id=d0f0ac56b34b28e80223d7086b4decdf027c27ed> _______________________________________________ Lede-dev mailing list Lede-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/lede-dev
