ZFS on a single core RISC-V hardware with 512MB

Don't know why anyone hasn't made such a board a priority. Seems like a sweet spot.

Yeah I would love not being dependent on x86 and its horrid UEFI mess. Then again... I believe technically ARM (and even RISC-V) board manufacturers can also make something similar. Let's hope that doesn't become a thing though.

Why not? I've been working from the view that UEFI is the one of the few things worth keeping from x86_64 - I do not want to deal with every board having its own special boot process that prevents one disk being able to boot different machines. And UEFI is already here and works, so why reinvent the wheel?

RISC-V took steps to prevent chaos.

The application profiles (like RVA22) have a bunch of requirements on hardware that must be present, the boot process and interface the firmware offers to the OS (i.e. opensbi).

Ok but does any of that work in practice? Can I write a random distro ISO to an SD card and expect it to work on any RISC-V board that has the same pointer size? Cause that’s how it works in PC land thanks to ACPI tables.

I just checked the Ubuntu RISC-V download page and it has 2 different ISOs for 2 boards from the same vendor! And apparently those are the only 2 boards with ISOs available 0_o

Yes, you will be able to, at some point.

No board out there is RVA22 compliant, as RVA22 itself isn't done and closed. It is expected to be this spring.

By the time large scale production of boards happen and they ship to the masses, this will be a solved problem.

I do not expect this to happen this year. Maybe the next it'll start to pick up.

So you want yo be dependent on u-boot plus sketchy binary blobs mess?

Now there’s a hot take! In PC land the same bootloader, kernel, config files, etc will work in pretty much computer. Hot swappable components are the norm here.

Meanwhile in ARM/RISC-V embedded land, every chip and every board is its own special snowflake. With no ACPI/UEFI, someone’s gotta hardcode the config of every device on every board, including the ones inside the SoC. Naturally the communities around these boards are even more fragmented than Linux distros already are.
