Red Hat Enterprise Linux 10 and CentOS Stream now offer RISC-V CPU ISA support, targeting SiFive HiFive P550 dev boards. Discover key changes, developer tools, and commercial implications of this open-source milestone.
RHEL 10 & CentOS Stream Embrace RISC-V Architecture
The RISC-V CPU ISA has gained significant traction in enterprise computing, and Red Hat Enterprise Linux (RHEL) 10 is now offering a developer preview for this open-standard architecture.
Following suit, CentOS Stream has introduced initial RISC-V support, reinforcing its role as the upstream source for RHEL.
This move aligns with Red Hat’s strategy of focusing on a single hardware platform—the SiFive HiFive Premier P550 developer board—to ensure full OS bootstrap capability, from source code to a graphical desktop environment.
Key Developments in RISC-V Support
Full-stack compatibility: Dozens of packages modified for riscv64 architecture
Developer-ready tools: Comprehensive suite for software engineers
Upstream integration: Majority of patches already merged into CentOS Stream dist-git
Pending updates: Remaining out-of-tree patches to be released June 1, 2025
"Red Hat’s approach was to focus on a single hardware platform and perform a full bootstrap of the operating system... up to a graphical desktop complete with developer tools." — CentOS Blog
Why This Matters for Enterprise & Developers
1. Commercial Viability of RISC-V in Linux
With RHEL 10, CentOS Stream, and Fedora 42 backing RISC-V, enterprises can now explore:
Cost-efficient alternatives to proprietary ARM/x86 solutions
Custom silicon development with open-standard ISA
Long-term support (LTS) via Red Hat’s enterprise-grade ecosystem
2. Hardware Focus: SiFive HiFive P550
The initial support centers on SiFive’s HiFive Premier P550, a high-performance RISC-V board designed for:
✔️ Embedded systems development
✔️ Cloud-native workloads
✔️ Edge computing applications
3. Future-Proofing Open-Source Infrastructure
CentOS confirms:
*"The upstreaming process will continue post-June 2025."*
This signals long-term commitment, ensuring compatibility with next-gen RISC-V chips from companies like NVIDIA, Intel, and Qualcomm.
