Support for USB Device pass through is being worked on by a student at the Bucharest Polytechnic University. This effort is essentially a port of the feature from Intel's Acorn hypervisor which is based on bhyve ... https://github.com/FreeBSD-UPB/freebsd-src/tree/projects/bhyve_usb_passthrough The UPB team has quite a few projects that would benefit from more support from the FreeBSD Foundation. They've asked for feedback and review of many bhyve related features that have been developed over the past few years. Unfortunately most of that work has been gathering dust in their github repository. This includes work on features such as warm migration, live migration, improved checkpoint file support, improved multiple checkpoint of devices, more sophisticated disk file formats such as qcow2 and vmdk via libvdsk that could help checkpoint disk images, etc. It would be incredibly helpful if the Foundation could offer some help getting some of this code reviewed and provide feedback so that it has a chance of being committed at some point in the future. -Matthew On 11/30/2021 1:30 PM, Michael wrote: > > > -------- Original Message -------- > From: Michael <mike@reifenberger.com> > Sent: November 30, 2021 11:03:13 AM GMT+01:00 > To: freebsd-hackers@freebsd.org > Subject: Call for Foundation-supported Project Ideas > > Hi, > one missing feature is USB device pass through for bhyve. > That would be quite handy for passing unsupported USB devices > to Linux/Windows on Laptops where a controller pass through isnt > possible. > > > -------- Original Message -------- > From: tux2bsd via freebsd-hackers <freebsd-hackers@freebsd.org> > Sent: November 30, 2021 8:35:36 AM GMT+01:00 > To: "freebsd-hackers@freebsd.org" <freebsd-hackers@freebsd.org> > Subject: Call for Foundation-supported Project Ideas > > Hi Joe > > Call for Foundation-supported Project Idea, well not a project but an item of importance in my opinion (the hostile forums disagree with me). > > Some help to fix freebsd-update , a very longstanding poor performance problem I took the time to investigate and provide an attempt to fix, > https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=258863 > > I've been working with Colin Percival towards providing/fine-tuning a workaround but the program itself is monolithic and very intertwined which means a seemingly trivial fix is actually a nightmare - the goal posts keep changing with each step forward.
