![]() ![]() The reasons for pushing this transition so fast are varied, and not always bound to the lack of royalties of this standard or the ideal of open hardware, which is not often on the radar of most tech manufacturers. The first obstacle was predictably the lack of suitable and powerful enough silicon for the new software, and the next - which was thankfully solved quite fast - was porting the entire kernel to a new architecture.īut now, with Linux support approaching full stability on a variety of RISC-V chipsets, distributions like Alpine starting to add support for RV64 packages, and an increasing quantity of chips powering Linux single board computers which retail for prices as low as $12, another challenge for most consumer producers occurs: how to turn this into a competitive ecosystem for Android smartphones? The Sipeed Nezha is a $99, Raspberry Pi-like SBC powered by Allwinner D1 (via LinuxGizmos) ![]() ![]() In fact, it took some years to see the Linux kernel running on RV64 (and partially RV32). And although the RV64 standard is not yet fully RV32-compatible, the two are, except from some minor divergences, closely associated products of the same family. The RISC-V ISA is commonly divided into two architectures, namely RV32 and RV64, covering 32-bit and 64-bit register sizes respectively. 3 min read The Sipeed Maix Amigo kit from 2020 was among the first RISC-V PDAs. ![]()
