I managed to build fully operational Haiku for x86_64: Why MergeObjectFromObjects1 rule is needed? - #21 by X512. But Clang build is not yet officially supported and it require some patches to produce working system. Haiku buildtools are GCC-based, there are no Clang-based buildtools for now.
Very cool!
I figured about the buildtools at least.
Hi @X512, @Coldfirex has suggested we add the RISC-V port to the Haiku port status page (Haiku port status | Haiku Project), so I’m working on that right now.
Could you have a look at the ports tables already present and let me know what values the RISC-V ports entries would have? For example, the x86 ports table has the different platforms listed, the different targets, the status and the status of work on critical components like the app_server, so what would the RISC-V table list as platforms, what would be the different targets and the status of work?
All 3 items (Haiku Loader, Haiku Kernel, Application Server) are working. TinyEMU (raw platform), Qemu (raw platform, SBI/EFI) are supported. Real hardware is not yet tested. Remaining major problems are partially broken libstdc++ and many packages not yet compiled such as Mesa, WebKit.
Most of kernel code is not yet submitted to Haiku source tree because cleanup is needed (removing temporary workarounds, code style cleanup). Only raw platform boot loader code (haiku_loader.riscv
) is already submitted, but it is a bit obsolete for now (machine-mode services and MMU page table initialization were recently added).
Official nightly builds are not yet operational, I provided my own builds if someone want to test it (it is also a bit obsolete for now).
@X512 Thanks for the info, I’ve added your port to the ports status page. You can view the commit on GitHub here:
AHCI (SATA disks) are working. The problem was here in “packed” struct attribute that cause per-byte access to MMIO registers instead of 32 bit access.
Also PCI register allocator was improved to support proper alignment (register addresses should be aligned with reported register size). Some hardcoding was removed.

I get swapped kernel and user address space ranges working. Now kernel can use high addresses and user can use low addresses as it usually done. Address ranges can be configured here (some address ranges hardcoding was removed), system still can be compiled and run with old address ranges. problem was addressed here and here.
It do not affect userland applications binary compatibility, but it affects kernel modules because of IS_USER_ADDRESS/IS_KERNEL_ADDRESS macro.
i get the feeling when you are done, many bugs from hardcoded structures will be fixed.
again, your work is inspiring and appreciated
IMO the RISC-V port status is misleading (everything is green), I would amend at least “Under development in a developer branch”, so that no one expects something buildable in the master branch.
Maybe. Someone can add this note.
You can checkout to hrev55144, apply patchset and compile operational RISC-V system.
I’ll edit that page on the website.
Just a quick status update. After the relation chain in http://review.haiku-os.org/c/haiku/+/4435 is reviewed and merged, stock nightly images should boot on the SiFive Unmatched!
There will be bugs to hammer out… and SMP still needs completed, but this represents the first non-x86 architecture port which fully boots to a desktop!!!
Nice work @X512 !!!
Nice work to you too, and thanks for reviewing/cleaning/merging the patches and bringing it up to what it is now.
This is absolutely wonderful work.
Thank you to everyone involved at Haiku.
It was great to see X512’s fruits of labour on YouTube!!
Back in the day I ran BeOS on a twin Celeron Abit (I believe) motherboard and was thrilled by the fun factor and performance of BeOS. Haiku btw is now on my laptop.
Like others on this thread I to am waiting for the HighFive motherboard to arrive. The risk-v ISA is the future. BeOS should have been an overwhelming success all those years ago but failed on the x86 platform, Haiku developers can now take this rewritten OS to new levels, especially on risk-v architecture. The publicity for Haiku will be fantastic.
Kudos to you all
This is pretty cool! I would like to see the teapot spin
Fixed running latest Haiku revision for riscv64 by downgrading to icu-57.2.2
. Current haikuports.cross icu-67
riscv64 build seems broken.
icu67 is broken for all working architectures according to https://github.com/haikuports/haikuports/blob/master/dev-libs/icu/icu67-67.1.recipe
probably icu66 should be used for now (in both bootstrap and non-bootstrap).
Yet another RISC-V virtual machine that theoretically can be used with Haiku.
