llama.cpp b12030 fixes hexagon DMA transfer issues across platforms

By PulseAugur Editorial · [1 sources] ·

The llama.cpp project has released version b12030, which includes a fix for DMA transfers on the hexagon architecture when strides exceed 24 bits. This issue could lead to truncated strides and incorrect addresses for large memory transfers. The update refactors fallback paths within the hex-dma component to reduce duplication and ensures compatibility across various operating systems including macOS, Linux, Android, and Windows, with specific configurations for Apple Silicon and openEuler.
