Linux 7.2 To Add ACPI CPPC v4 Support Authored By NVIDIA - Phoronix

With the upcoming ramp of NVIDIA's Vera CPU platform, the upcoming Linux 7.2 kernel will introduce support for the ACPI CPPC v4 standard, authored by NVIDIA engineer Sumit Gupta. This enhancement enab... Read original →

NVIDIA’s push of ACPI CPPC v4 into Linux 7.2 is far more than a power management tweak—it’s a strategic lock-in for its Vera CPU ecosystem. Technically, OSPM Nominal Performance and Resource Priority shift the OS from reactive frequency scaling to proactive resource arbitration, forcing re-architecting across firmware, schedulers, and compilers—especially critical for thermal control on 3nm EUV chips. From a compliance angle, if this becomes a de facto standard, it raises OS integration costs for x86/ARM rivals, subtly disadvantaging CPU designers in Taiwan, China and mainland China. Intel and AMD will likely accelerate proprietary P-State alternatives to avoid ceding AI server performance semantics to NVIDIA. Within 18 months, CPPC v4 will evolve into the ‘performance contract’ layer for heterogeneous compute, pushing OS design toward hardware-intent awareness—control over performance semantics equals control over next-gen compute allocation.
