These days the controllers are more or less complete systems in itself. A nice proof of that is a talk of a guy that installed Linux on his harddrive ... the harddrive controller that is :) I can't find a link to the video now :(

I found the video again: http://spritesmods.com/?art=hddhack (the link to the actual video is on that page)
Have fun :) |
Thanks. That's really cool and disturbing. It also makes me wish I could repurpose my old hard drives, and that I'd gone into hardware/electrical engineering (far from the first time).

It has been quite some time since we posted in this topic, and I'd like to give an update:
What works:
- EFI Booting with grub (instead of only u-boot), which requires quite some patching to grub
- Recent 5.13 kernels, the amount of patching required is becoming lower and lower (which is a good thing)
- NFS Client
- Bluetooth (using a USB BT dongle), i was able to play music from a NFS share to a bluetooth speaker withing bluez-alsa
- OpenVPN, OpenVPN-NL, OpenSC, pcsc-lite and ccid, so you can even use smartcards to setup a VPN, it can handle 5.5-6.0 MB/s of VPN traffic
- I don't have a GPU, but i can use xdm and awesomewm via a remote X server
- Playing videos over ssh with mplayer and aalib 
- Alsa with a USB audio device
What doesn't work:
- RTC (there are some unofficial patches, but since it's the same chip that does power regulation I'm not a fan of unofficial patches in this area)
- Reboot (same issue as previous, same chip that handles it)
- Scummvm (but that's due to the remote X server, it uses shared memory with the X server for graphics)
It still amazes me how much packages aren't even keyworded for RISC-V and still compile and function properly. I guess most programs are already written to be compiled on different architectures (like arm, mips, x86, amd64) and that helps RISC-V a lot

pa4wdh, what board you have? Nice improvements.How's the compiling times?
...or have you set up a binhost?
How's the power consumption?

It's the Sifive HiFive Unmatched: https://www.sifive.com/boards/hifive-unmatched

I always compile from source, no exceptions . Compile times are long but not excessive.
As an indication, this is way qlop says about gcc:
| Code: | 2021-07-24T18:29:29 >>> sys-devel/gcc: 7:56:20
2021-09-15T12:53:28 >>> sys-devel/gcc: 7:52:47 |
This is done with -j5 in maketops and /var/tmp on tmpfs.

I posted that earlier in this topic, so i'll quote myself
| Quote: | | I did some power measurements and it consumes 37 watts for the board and SSD (and probably some losses in the PSU). My J1900 which has double the performance, and an SSD and a (built-in) GPU uses 33 Watts. |

Pine64 will release their RISC-V SBC: | July update wrote: | - Star64
- Congratulations to Gav for being the first to solve the riddle!
- Star64 is in final layout stages and we want to bring it to the market soon
- Uses StarFive JH7110 64bit CPU paired with BXE-2-32 GPU
- Available in 4 and 8GB RAM configuration
- Equipped with 2x Gigabit Ethernet ports (a variant with 1x GbE will be available later on for $5 less), PCIe, USB 3.0 as well as 2x USB 2.0 and GPIO
- Follows Quartz64 model-A pricing and footprint

... but as to when. I think, considering the current global situation - maybe next year.

The hardware seems interesting indeed.

Really, that fast?
