Overview ¶
Package dmaheap provides buffer allocation via Linux dma-buf heaps (/dev/dma_heap/system). This is a fallback allocator when AIDL/HIDL gralloc services are unavailable.
Buffers allocated this way are plain dma-buf FDs without gralloc metadata. They work for camera HALs that can import raw dma-buf FDs but may not work with HALs that require gralloc-specific handle formats.
