Hi,

There is a relationship to recent AI Laptops
and how much memory they can access and/or
share with the GPU in accelerator mode.

A fine grained machanism did not exist for
budget laptops. Its a feature which a) needs
modern ( not older than ca. 20 years ) OS

and b) needs modern (not older than ca.
20 years) hardware.

Check for yourself:

NX bit
https://en.wikipedia.org/wiki/NX_bit

Executable-space protection
https://en.wikipedia.org/wiki/Executable-space_protection

So if you use an older PC not only use Norton
Commander, but better also Norton Antivirus. LoL
But the architecture of the OS and hardware

can be more complex, than to have a bit on the
physical memory page level. You might also organize
it via logical views, and combine it with

virtualization i.e. swapping to hard disks. Hard
and OS support varies as well there, how far
translation tables can manage such a bit effeciently.

See also:

3 GB barrier
https://en.wikipedia.org/wiki/3_GB_barrier

Physical Address Extension (PAE),
https://en.wikipedia.org/wiki/Physical_Address_Extension

In as far the relationship to recent AI Laptops
is that for example Windows 10 32-bit editions
could only adress 4 GB. What surely helps are

64-bit editions. My Windows 11 AI Laptop has
32 GB total memory, and can share 16 GB with the
GPU. I didn't check yet how programming languages

such as JavaScript, Python and Java behave. Their
runtimes have usually an overlayed memory model.
And tagged pointers or compressed points can reduce

the available memory space. But LLM software when
used for local AI, usually tries to tap into
very large portions of memory, and recent trends

are virtualization of local LLMs:

Maximize throughput with PagedAttention. Advanced
scheduling and continuous batching ensure peak
GPU utilization.

Brain food on how to evolve pi-WAM and what
does the concept of GPUBuffer mean in WebGPU?
Mostlikely the logical model here is coprocessor

device bound memory, and the physical can
realize it via system memory sharing. But I wrote
about that already in my post:

But how can you deploy. when its ROM?

Bye
