llama.cpp adds UPSCALE support to hexagon backend

By PulseAugur Editorial · [1 sources] ·

The llama.cpp project has released version b11982, introducing support for the UPSCALE operation within its hexagon backend. This update includes optimizations for nearest and bilinear upscaling, improved handling of non-contiguous rows and dimension collapsing, and the use of vgather for efficiency. Additionally, a permuted UPSCALE test has been added to specifically address scenarios involving Qwen3 VL image-to-text tasks. AI

IMPACT Enhances image upscaling capabilities within the llama.cpp framework, potentially improving performance for multimodal models.
