Systems and methods for accessing and managing a computing system memory

A method comprising:

• maintaining, by a first processor, a request log of with entries identifying requests that have been made to pages stored in a second memory;
• generating, by the first processor, an indication for a second processor to process the request log when the number of entries in the request log reaches a first threshold;
• increasing the first threshold responsive to determining a rate of indication generation is greater than a given range;
• and
• decrease the first threshold responsive to determining the rate of indication generation is less than the given range
• processing, by the second processor, the request log responsive to detecting the indication;
• and
• determining, by the second processor, whether to migrate physical pages from the second memory to a first memory.

An apparatus comprising:

• a graphics processing unit (GPU);
• a central processing unit (CPU);
• a first memory;
• and
• a second memory;
• wherein the GPU is configured to:
• maintain a request log of with entries identifying requests that have been made to pages stored in the second memory;
• generate an indication for the second processor to process the request log when the number of entries in the request log reaches a first threshold;
• wherein the CPU is configured to:
• increase the first threshold responsive to determining a rate of indication generation is greater than a given range;
• and
• decrease the first threshold responsive to determining the rate of indication generation is less than the given range;
• process the request log responsive to detecting the indication;
• and
• determine whether to migrate physical pages from the second memory to the first memory.
