Hi, This patch series adds UAS (usb attached scsi) emulation to qemu. UAS is a protocol which uses usb3 streams and this is intended to be the playground when adding full usb3 support to the xhci emulation. It turned out to also be a heavy stress test for the ehci emulation, so this patch series includes a bunch of ehci bugfixes too.
Patch #4 is not ready for merge yet, I still have to think about a better way to fix the issue described in the commit log. Reviews & comments are welcome. cheers, Gerd Gerd Hoffmann (4): ehci: fix ehci_qh_do_overlay ehci: fix td writeback usb: add usb attached scsi emulation [wip] ehci: don't flush cache on dorbell rings. docs/usb-storage.txt | 38 +++ hw/usb/Makefile.objs | 1 + hw/usb/dev-uas.c | 792 ++++++++++++++++++++++++++++++++++++++++++++++++++ hw/usb/hcd-ehci.c | 45 ++-- trace-events | 14 + 5 files changed, 869 insertions(+), 21 deletions(-) create mode 100644 docs/usb-storage.txt create mode 100644 hw/usb/dev-uas.c
