Since RISC-V International ratified the RVA23 Profile in October 2024, the standard has seen wide adoption across the industry. But at the Linux Kernel level, coverage of RVA23 mandatory extensions remained incomplete.
Daniel Thompson, tech lead for the RISCstar toolchain, shares a few of the technical details behind this new toolchain for RISC-V.
The 2025 RISC-V Summit China reached an unprecedented level of excitement, drawing a record-breaking crowd of over 4,000 attendees. The main venue was filled to capacity, with many standing along the walls just to be part of the event. This was my second time attending the RISC-V Summit, since starting development work on RISC-V, and in just two days, there was a lot to take in and reflect upon.
New hardware designs must go through an initial “bring-up” process to ensure it functions as intended
Today, RISC-V is starting to look less like a fringe alternative and more like a strategic necessity—especially in China.
Today’s new hardware is impressive, but it’s easy to overlook the critical role software plays in maximizing hardware performance
This talk highlights the importance of upstreaming support for RISC-V to the Linux kernel, urging vendors from China’s RISC-V industry and academia to take a more active role in contributing support for RISC-V to the open-source ecosystem
