That kind of seems crazy to me, considering OpenBSD has worked perfectly fine with every wifi capable device I've tested it on. Granted, most of them were older machines.
Is this just an artifact of FreeBSD primarily focusing on server hardware rather than consumer/end-user stuff?
Basically no one supports Broadcom SoftMAC WiFi cards very well, but OpenBSD just doesn't. I have a 2015 MacBook Air with a BCM4350 where the recommended fix is to go buy a FullMAC card from a similar vintage MacBook Pro and just cope with the fact that the card barely fits in the case and can't be secured properly.
Why? Nothing wrong with running your network interface in a VM. There are reasons for doing so even if drivers aren't an issue. Qubes OS does this, for instance, for security reasons.
Windows also does. Almost everything is a VM in windows these days.
It's just how things work these days. If you'd say "I run my VPN client in a docker container" it would raise a lot less eyebrows. Yet it's not very different, really.
Though conceptually I'd frown at having to run Linux. I'd prefer upgrading the hardware to a supported chip.
Definitely not independent kernels but my guess is he's referring to Virtualization-Based Security (VBS) - it gets turned on by default if your Win10/11 system has virtualization enabled.
One such example security solution is memory integrity, which protects and hardens Windows by running kernel mode code integrity within the isolated virtual environment of VBS. Kernel mode code integrity is the Windows process that checks all kernel mode drivers and binaries before they're started, and prevents unsigned or untrusted drivers or system files from being loaded into system memory.
Why not? FreeBSD has never been intended as a batteries included, everything "just works" out of the box OS. It's meant to have a bare minimum install and let the user choose how things are set up. You can disagree with that philosophy, but that's not an indictment of FreeBSD. Just go use something that aligns better with your preferences.
But then you’re stuck running Linux as your primary OS, which is a huge drawback.
FWIW, I’ve done both, FreeBSD with a virtualised OpenBSD for WiFi, and currently I run Arch so I can do gaming, with FreeBSD virtualised for development. I’m kind of looking to go back to my previous setup.
I agree that 9/10 is a bit of a strange score there, but it's not all that bad: You can get a $15 wifi dongle and use that instead. It occupies a USB port and looks a bit ugly, but it's still a fairly easy workaround.
I'd like to know more about what it takes to turn on PCI pass through for laptop hardware. On desktops and servers it's typically the IOMMU setting in the BIOS. Is that also commonly available on laptops?
Some years ago, I was workig with FreeBSD on an old laptop. The laptop had a wireless adapter that ostensible should be supported, but was not.
After some digging, I realized the driver was just missing some PCIe device identifiers. I added them to driver and bam my WiFi is working without issue.
I tried to submit a bug report and patch, and it got positive feedback at first any changes even got committed. But then I learned why it’s better to not even try.
Apparently this was a known issue, but only in the heads of the FreeBSD wireless developers. They had their reasons for not adding the device, but the reasons did not appear to be documented in mailing lists or docs until my thread. At that point I realized it’s not worth it to try and contribute to such large projects as I just lack the decades of institutional knowledge of the system.
Anyway, I’m not sure it ever got released. I believe there’s an umbrella bug somewhere left after the version my patch supported went out of support.
