That is actually a pretty good question.
The Risc-V arch port is currently in an "orphaned" state, as noted in MAINTAINERS.yaml.
The original contributors have not been heard from for some time.
Oh... I didn't check MAINTAINERS.yaml.


The project could really use someone to step up and take over maintainership of this arch.
Hmm... Can I help this issue?


I have also been frustrated by this, as there are some other recent contributions to enable user mode on Risc-V, but finding people to review the code, or help with some of the HW issues Alexandre is seeing when testing it, has been difficult.
Are you talking about this PR?
https://github.com/zephyrproject-rtos/zephyr/pull/27063

I have HiFive Unleashed (RV64 board) and buy a HiFive1 Rev.B (RV32 board).
Maybe I can get it in this week. After I receive it, I can help creating
board config for these boards and basic testing on RV32/RV64 real HW...

Hello,

Who is maintainer of RISC-V porting area?
I want to discuss about SMP support for RISC-V with maintainer(s).

Near a week ago, I posted SMP support for RISC-V and few days ago
Jim Shu from Andes Technology posted another version.

In such case what should I do for merging SMP support onto upstream?
Simply maintainers needs more days for reviewing both patch sets?
Or do I need to add more works (ex. unifying both patch set)?

Best Regards,
Katsuhiro Suzuki
