Effective PCIe utilization by PCIe TLP coalescing

A data storage device, comprising:

• a memory device;
• and
• a controller coupled to the memory device, the controller configured to:
• initialize a weight value, wherein the weight value affects a maximum threshold value of a timeout counter;
• define a maximum size value of a received command;
• receive a new command;
• determine if the new command received is greater than or less than the maximum size value of the received command;
• adjust, based on the determining, the weight value;
• adjust the maximum threshold value of the timeout counter;
• and
• define a maximum payload size (MPS).

A data storage device, comprising:

• memory means;
• and
• a controller coupled to the memory means, wherein the controller is configured to:
• determine whether a new request is continuous with a previous request or a merged request stored in a buffer, wherein the determining comprises checking a timeout counter for the previous request or the merged request, and wherein each buffer has a corresponding timeout counter;
• adjust the timeout counter based upon data traffic;
• and
• either:
• update a length of the previous request or the merged request stored in the buffer to a new length that includes the newly generated one or more requests;
• or
• send the previous request or the merged request from the buffer and push the newly generated one or more requests to the buffer.

A data storage device, comprising:

• memory means;
• and
• a controller coupled to the memory means, wherein the controller is configured to:
• determine whether a new request is continuous with a previous request or a merged request stored in a buffer;
• and
• adjust a timeout counter based upon data traffic, wherein the adjusting the timeout counter comprises:
• initializing a weight value, wherein the weight value is adjusted based on incoming commands;
• determining a maximum size value of a received command;
• determining if the incoming commands are greater than or less than the maximum size value;
• and
• either:
• increasing, if the incoming commands are greater than the maximum size value, the weight value, wherein increasing the weight value increases a maximum threshold value;
• or
• decreasing, if the incoming commands are less than the maximum size value, the weight value, wherein decreasing the weight value decreases the maximum threshold value.
