  • I’m somewhat confused what you’re asking here. The two technologies that you mentioned do not provide the ability to share a PCIe device to my knowledge which is what I understand you wish to do. The first allows network cards to directly access host memory and perform data transfers without consulting the CPU while the other allows for the sharing of a PCIe root or bus, not allowing multiple systems to access the same hardware device at the same time.

    I’ve heard of proprietary solutions, which makes sense because if you want to virtualize multiple instances of one physical hardware device I don’t see how you can do that efficiently without really intimate knowledge of device internals. You have to have separate state for these things, and I think that would be really challenging to do for an open source project.

    Anyway, just thought I would open up the discussion because I didn’t see any other comments. I hope to learn something.





  • It was a solution to a Lutris bug. Basically, flatpak containers can use these things called portals to gain access to specific files and directories via a file chooser rather than broad access or manually assigned access.

    In this case, my wine installation was crashing because some part of it was trying to obtain a lock on a directory object, which is an unsupported feature when accessing a directory through a portal. The error message is something completely unrelated like can’t draw window with a string of hex values. It took me a few hours to track down the real root cause.

    Oh well. Works on my machine. Also, there’s a fix on the development branch now. I made a write-up, posted it, and it’s all gone. I should have known better honestly. It works great for some people but anybody can arbitrarily receive unfair treatment with no recourse at any time. I’m satisfied knowing that eventually the fix will get out to everybody eventually. It’s just a shame I couldn’t leave a signpost behind.






  • I still have drawings I made in MS Paint on Windows 95 when it had just come out, my first text document, and the first report I ever typed in grade school.

    Btrfs snapshots of the root volume in RAID1 configuration with 8 hourly, 7 daily, 3 weekly, and automated rsync backups to NAS, with primary and secondary offsite, physically disconnected backups stored in sealed, airtight, and waterproof containers at two different banks prepaid storage and with advanced directive in the event of my demise.

    Bit of a hobby really. I acknowledge it’s completely unnecessary. I don’t like to lose data.
