NVIDIA "Blackwell-Next" GPU codename appears in Linux kernel patch for VFIO driver
By
WhyCry
Summary
NVIDIA engineers are preparing Linux kernel support for next-generation GPUs codenamed "Blackwell-Next." The name was spotted in a Linux kernel patch for the NVGrace-GPU VFIO driver, which adds a CXL DVSEC-based readiness check for Blackwell-Next GPUs while maintaining the existing BAR0 polling path for current Grace Blackwell hardware. The patch is part of the VFIO subsystem work for the Linux 7.2 cycle, updating how the driver checks GPU memory readiness after probe or reset.
