New API for HCI drivers to synchronize hardware completion interrupts, synchronous aborts, and asynchronous timeouts: - When submitting an xfer to hardware, call usbd_xfer_schedule_timeout(xfer). - On HCI completion interrupt for xfer completion: if (!usbd_xfer_trycomplete(xfer)) return; /* timed out or aborted, ignore it */ - In upm_abort methods, call usbd_xfer_abort(xfer). For HCI drivers that use this API (not needed in drivers that don't, or for xfers like root intr xfers that don't use it): - New ubm_abortx method serves role of former *hci_abort_xfer, but without any logic for wrangling timeouts/callouts/tasks -- caller in usbd_xfer_abort has already handled them. - New ubm_dying method, returns true if the device is in the process of detaching, used by the timeout logic. Converted and tested: - ehci - ohci Converted and compile-tested: - ahci (XXX did this ever work?) - dwc2 - motg (XXX missing usbd_xfer_schedule_timeout in motg_*_start?) - uhci - xhci Not changed: - slhci (sys/dev/ic/sl811hs.c) -- doesn't use a separate per-xfer callout for timeouts (XXX but maybe should?) - ugenhc (sys/rump/dev/lib/libugenhc/ugenhc.c) -- doesn't manage its own transfer timeouts - vhci -- times transfers out only on detach; could be adapted easily if we wanted to use the xfer->ux_callout |

NetBSD
NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices.
Building
You can cross-build NetBSD from most UNIX-like operating systems. To build for amd64 (x86_64), in the src directory:
./build.sh -U -u -j4 -m amd64 -O ~/obj release
Additional build information available in the BUILDING file.
Binaries
Testing
On a running NetBSD system:
cd /usr/tests; atf-run | atf-report
Troubleshooting
- Send bugs and patches via web form.
- Subscribe to the mailing lists. The netbsd-users list is a good choice for many problems; watch current-users if you follow the bleeding edge of NetBSD-current.
- Join the community IRC channel #netbsd @ freenode.
