This patch takes advantage of block transfer interrupts on Intel XHCI controllers which is used during isochronous transfers. Because of a bug in hardware (see usb_host_isoc_bei.patch header), this feature has been disabled for Intel leading to up to 8000 interrupts/s for isochronous transfer causing severe CPU consumption on Genode. With this commit we lower host driver consumption to normal levels. issue #4149 |
