Radxa Dragon Q8B: A Laptop Cosplaying as an SBC?

What would it cost to fund swe and design professionals to write a 9front port with a haiku skinjob to hit milestones at 9, 18, 27 month intervals? the incubation period for Macintosh, NeXTSTEP, BeOS, HarmonyOS Next would have estimates.

> What would it cost to fund swe and design professionals to write a 9front port with a haiku skinjob ...

Patches welcome. The community is very small and most everyone involved has jobs. There is also a tendency to only support the most common *useful* hardware instead of Raspberry Pi clone du jor.

As for a haiju skin job, see lola, a new window manager: https://shithub.us/aap/lola/HEAD/info.html I think it has a BeOS theme, if not, likely an easy patch because the dev designed it to be very hackable vs rio.

Not sure what any of this means. 9front is a rolling fork. People submit patches and if useful, are applied. sysupdate(8) is a small script that binds the 9front git repo over root and then runs git/pull. Then you run 'mk install' in /sys/src.

I just wish they had 2x5GbE like the Orion O6. i/o heavily matters for my compute nodes.

I wonder if 802.3ad bonding can bring 5gbit/s

modeless | an hour ago

Seems like you could add that pretty easily via USB and/or M.2. Either should have the necessary bandwidth.

preisschild | an hour ago

I would use the m.2 e keys for sata and x4 m key for nvme ssds. That only leaves pcie gen3 x2.

I want to run a distributed network storage (ceph)

It says that it has four 10 Gb/s USB ports (2 Type A and 2 Type C).

It is unknown whether the ports are independent, or some of them or all of them are connected to an internal hub.

Even if they were connected to a single CPU port through an internal hub, if you used two 5 Gb/s USB Ethernet interfaces you would get close to full speed for them.

Having 10 Gb/s USB instead of the so-called "5 Gb/s" USB (in reality 4 Gb/s), provides much more additional I/O throughput than having 5 Gb/s RJ45 instead of 2.5 Gb/s. I agree that having 5 Gb/s Ethernet would have been nice, but it is much more valuable that it has 10 Gb/s USB, which is very rarely encountered on Arm-based computers.

They’re independent

I wonder how well a usb 10gbit ethernet adapter would work then

But I really apprecate your reply!

I'll definitely buy one for testing when they become available for reasonable prices <500EUR for 16gig memory

Hmm, is it possible to skip the Ethernet adapters in a configuration of USBC-Eth-Eth-USBC and connect USBCs directly one to another?

This is a one beautiful SBC.

Apparently we might be able to run OpenBSD on it [0]

FreeBSD is unclear [1]

If I could find a 6GB Q6A in stock (or Radxa eMMC, or fan-powered case, or most Radxa products in general) I would celebrate this announcement but they seem to be in small batch mode right now.

I hope Linux support for these chips matures quickly. Qualcomm's laptop chips are the only serious competitor to Apple's M-series in single core performance and power efficiency. Intel and AMD are both far behind.

jauntywundrkind | an hour ago

Yes! But these are rebadged 5 year old chips.

rigonkulous | an hour ago

I hope not just Linux support for these chips matures - but that the rest of the fabless chip vendors get a leg up as well, because .. The world needs non-Apple/-Qualcomm variants of this hardware architecture, imho.

Pretty darn quick.

I want to be able to buy ARM boards like I'm buying ITX PC boards. I don't want a special build of Linux from the SBC OEM, I don't want weird bootloaders, firmware and other embedded-like stuff. I just want an ARM-based PC board for my desktop and server closet (so Ampere stuff is out of the picture unfortunately).

modeless | an hour ago

Qualcomm has been upstreaming kernel support for their chips recently, so I'm hopeful.

cogman10 | 12 minutes ago

It seems they've been stopping short of completion. Once the next gen chip is released, they are done and stop working on fixing issues.

Hopefully, with some time this gets better as it's not like they have to start from scratch with each generation. But it does leave a sour taste in my mouth that they quit so early before finishing.

preisschild | an hour ago

Yeah, I want edk2 uefi and mainline linux support at least for most functions (dont care about npu for example)

fragmede | 12 minutes ago

Why would you ask for a pony and then only want half? Let's get mainline support for all functions, like the NPU.

nubinetwork | 34 minutes ago

The O6 runs mainline pretty good, only hiccups I know of are gpu acceleration and the npu.

woodrowbarlow | 28 minutes ago

preach. and i want this to extend to phones too.

diabllicseagull | 56 minutes ago

I have been tinkering with the Windows Dev Kit 2023 which shares the same SoC as this board. Linux support has been improving but with only third party kernel patches. GPU support has been okay but I have noticed oddities at higher resolutions. Speaking of, none of the display port options could provide 4K at 120Hz so maybe this is one area that the Q8B can prove to be more capable; it is supposed to have an HDMI 2.1 port and two DP 1.4 capable usb-c ports.

A lot of these higher-end sbc have been out-of-stock for a while now, I've been trying to find an o6 since a few months.
