Merged on Friday for the nearly-over Linux 6.15 merge window were the RISC-V CPU architecture updates for this next kernel release.
RISC-V with Linux 6.15 brings build improvements thanks to a re-architecting of the Kconfig build system options around RISC-V for selecting sub-architecture features.
For the Linux 6.15 kernel with RISC-V there is also support for building relocatable non-MMU kernels, support for huge PFNMAPS to improve TLB utilization, support for runtime constants, new RISC-V instructions supported, and a variety of fixes.

I love that RiSC-V is already so well supported in the Linux kernel even though the hardware is not really out there yet. When decent hardware does arrive, a fairly mature ecosystem will be waiting for it.
Compare that to ARM which took quite a while. There is already more of a culture of getting device support into the mainline for RISC-V than for ARM even now.
I do think decent RISC-V kit is coming. The existing players like SciFive are getting there, we know big players like Qualcomm and Samsung have projects, and future disruptors like AheadComputing see RISC-V as their attack vector on the current industry. And for sure China is going to surprise with a decent RISC-V offering at some point—maybe Alibaba, maybe Huawei, or maybe someone else.
I’m still skeptical. The licensing model is certainly friendlier and I think that’s why more people are willing to give this a chance and put dev time into it. But the cost is still high and performance is trash.
I’m most interested in seeing what that team that splintered off intel to go all in on RISC-V come up with.
