Linux 7.2-rc2 Raising The Default RISC-V 64-bit CPU Limit To 256 Cores

A post merge-window change that landed in Linux Git overnight ahead of tomorrow's Linux 7.2-rc2 release is bumping the default limit on the number of supported CPU cores for RISC-V 64-bit. Now by default Linux will support up to 256 cores with RISC-V 64-bit kernel builds...

Why this matters
Why now

The RISC-V ecosystem is maturing rapidly, necessitating increased core count support as more complex designs emerge and gain traction in various compute domains.

Why it’s important

This upgrade removes a technical bottleneck for RISC-V 64-bit systems, enabling broader adoption in servers, AI accelerators, and high-performance computing, which are critical for future compute infrastructure.

What changes

Linux kernel now natively supports a higher number of cores for RISC-V 64-bit architectures by default, reducing configuration overhead and directly enhancing scalability.

Winners
  • · RISC-V hardware vendors
  • · High-performance computing sector
  • · AI compute infrastructure
  • · Cloud providers utilizing RISC-V
Losers
    Second-order effects
    Direct

    Increased performance and efficiency for RISC-V based server and embedded systems due to better utilization of multi-core architectures.

    Second

    Accelerated development and adoption of RISC-V in data centers and specialized computing tasks, potentially challenging established x86 and ARM dominance in specific niches.

    Third

    Further decentralization of the compute supply chain as RISC-V gains momentum in critical infrastructure, reducing reliance on proprietary architectures.
