Hi, Here comes a patch series with a bunch of updates for the ehci host controller. Two important changes: First ehci supports queuing now, i.e. more than a single packet per endpoint can be in flight at the same time, which improves usb-host performance. Second the wakeup rate is adaptive now, so ehci will have alot less wakeups when the usb bus is idle. Also a bunch of minor fixes and cleanups.
Post-freeze material. please review, Gerd Gerd Hoffmann (18): ehci: add EHCIPacket ehci: make ehci_execute work on EHCIPacket instead of EHCIQueue ehci: cache USBDevice in EHCIQueue ehci: move ehci_flush_qh ehci: add queuing support ehci: tweak queue initialization ehci: add async field to EHCIQueue ehci: move async schedule to bottom half ehci: schedule async bh on async packet completion ehci: kick async schedule on wakeup ehci: fix reset ehci: add ehci_*_enabled() helpers ehci: update status bits in ehci_set_state ehci: fix halt status handling ehci: remove unused attach_poll_counter ehci: create ehci_update_frindex ehci: adaptive wakeup rate. ehci: rework frame skipping hw/usb/hcd-ehci.c | 610 +++++++++++++++++++++++++++++++++++------------------ trace-events | 1 + 2 files changed, 408 insertions(+), 203 deletions(-)
