DMA
A European Union digital market regulation that entered into force in 2023. It requires very large platforms designated as gatekeepers to open interoperability, with the goal of breaking down monopolistic structures in digital markets and promoting interconnection between platforms.
Core Facts
The EU's Digital Markets Act (DMA) officially took effect in 2024, requiring Meta to enable interoperability with third parties.
The Epic lawsuit in the United States and antitrust investigations in multiple countries have put pressure on Apple's App Store policies.
欧盟《数字市场法》（DMA）已将数据可携权列为守门人平台的强制义务
Timeline (last 90 days)
Strata uses a separate thread to DMA the next layer's experts into a GPU ring buffer, overlapping computation and loading.
The core idea of GDS is to establish a direct DMA channel between storage and GPU memory, with data flowing from NVMe devices through PCIe switches directly into GPU memory.
In the Spyre dataflow architecture, once data placement planning is wrong, a core may spin idle waiting for DMA transfers.
A DMA (direct memory access) descriptor on Spyre refers to data movement instructions explicitly declared in the compilation output, used to transfer tensor tiles between off-chip memory and each core's scratchpad.
Apple has confirmed that some Siri AI capabilities will be rolled out in phases, initially delayed in some regions due to regulatory reasons such as the EU's DMA.
On the x86 architecture, the CPU and GPU typically share a cache-coherent view, while ARM SoCs handle cache coherency between the CPU and GPU in varying ways.
To run a driver designed for PCIe bus discrete graphics cards in an iPad environment, low-level challenges must be addressed, including address space mapping translation, DMA coherency, and bypassing or achieving compatibility with Apple devices' strict boot verification.
On ARM platforms, certain memory regions require the driver to explicitly perform cache flush or invalidation operations; otherwise the GPU may read stale values from the CPU cache, causing rendering errors or system crashes.
Apple's gatekeeper position over the App Store has begun to crack under pressure from the EU's DMA regulation
The EU's Digital Markets Act (DMA) imposes additional constraints on the differentiated pricing behavior of very large platforms.

50%UnverifiedThe DMA's interoperability obligations primarily target the basic functions of messaging, and many technical details remain to be clarified regarding how advanced features such as encryption and rich media can be made compatible across protocols.
50%UnverifiedThe inference engine uses a DMA streaming load strategy that prefetches the weights of the next layer from Flash storage via DMA while computing the current layer, in order to hide slow Flash read latency.
