Systems, methods, and apparatus for using a submission queue for write buffer utilization

1 . A method comprising:

receiving, from a host device, a first request to write first data to a memory device;

determining a first availability, based on a size of data in a write buffer, of the write buffer corresponding to a location to write the first data of the memory device;

adding the first request to a queue on the memory device based on determining the first availability;

determining a second availability of the write buffer;

retrieving the first data from the host device based on adding the first request and determining the second availability; and

writing the first data to the write buffer of the memory device.

returning a completion message to the host device based on writing the first data to the write buffer; and

writing the first data from the write buffer of the memory device to storage media.

3 . The method of claim 1 , wherein the first request is a submission queue entry (SQE), and wherein the method further comprises:

parsing the SQE; and

determining that the SQE is a write request.

4 . The method of claim 1 , wherein the first request is a submission queue entry (SQE), and wherein the method further comprises:

parsing a reclaim group (RG) and reclaim unit handle (RUH) from the SQE; and

wherein adding the first request to the queue comprises queueing the SQE in a first in first out (FIFO) queue, wherein the FIFO queue corresponds to the RG and the RUH.

5 . The method of claim 1 , wherein adding the first request to a queue comprises:

determining that the size of the data in the write buffer is above a threshold value; and

adding the first data to the queue.

6 . The method of claim 1 , wherein determining the first availability of the write buffer comprises determining that a size of data in the write buffer is below a threshold value; and writing the first data to the write buffer comprises:

writing the first data from the queue to the write buffer; and

removing the first data from the queue.

7 . The method of claim 1 , wherein the queue comprises a first indicator, wherein the first indicator corresponds to a location in a host memory of the host device, wherein the location in the host memory corresponds to the first data.

8 . The method of claim 1 , further comprising:

receiving, from the host device, a second request to read second data from the memory device; and

retrieving the second data from the memory device; wherein the write buffer is above a threshold value.

9 . The method of claim 1 , further comprising:

receiving, from the host device, a second request to write second data to the memory device; and

adding the second request to the queue on the memory device.

10 . The method of claim 1 , further comprising a second indicator, wherein the second indicator corresponds to a most recent first request.

11 . A device comprising:

a controller, wherein the controller comprises a write buffer, wherein the write buffer corresponds to a location to write first data;

storage media; and

a queue; wherein the controller performs operations comprising:

receiving, from a host device, a first request to write the first data to the storage media;

determining a first availability, based on a size of data in the write buffer, of the write buffer;

adding the first request to the queue based on determining the first availability, wherein the queue is a FIFO queue;

determining a second availability of the write buffer;

retrieving the first data from the host device based on adding the first request and determining the second availability;

writing the first data to the write buffer;

returning a completion message to the host device; and

writing the first data from the write buffer to the storage media.

12 . The device of claim 11 , wherein the first request is a submission queue entry (SQE), the completion message is a completion queue entry, and wherein the controller further performs operations comprising:

parsing the SQE; and

determining that the SQE is a write command.

13 . The device of claim 11 , wherein the first request is a submission queue entry (SQE), and wherein the controller further performs operations comprising:

parsing a reclaim group (RG) and reclaim unit handle (RUH) from the SQE; wherein the queue corresponds to the RG and the RUH.

14 . The device of claim 11 , wherein adding the first request to a queue comprises:

determining that the size of the data in the write buffer is above a threshold value; and

adding the first data to the queue.

15 . The device of claim 11 , wherein determining an availability of a write buffer comprises determining that the size of the data in the write buffer is below a threshold value; and writing the first data to a write buffer comprises:

writing the first data from the queue to the write buffer; and

removing the first data from the queue.

16 . The device of claim 11 , wherein the controller performs operations comprising:

receiving, from the host device, a second request to write second data to the storage media;

adding the second request to the queue,

and wherein writing the first data to the write buffer comprises:

determining that the size of the data in the write buffer is below a threshold value;

writing the first data from the queue to the write buffer; and

writing the second data from the queue to the write buffer.

17 . The device of claim 11 , wherein the queue comprises a first indicator, wherein the first indicator corresponds to a location in a host memory of the host device, wherein the location in the host memory corresponds to the first data.

18 . A system comprising:

a host device; and

a storage device, wherein the storage device comprises:

a controller, wherein the controller comprises a write buffer, wherein the write buffer corresponds to a location to write first data;

storage media; and

a queue; wherein the controller performs operations comprising:

receiving, from the host device, a first request to write the first data to the storage media;

determining a first availability, based on a size of data in the write buffer, of the write buffer;

adding the first request to the queue based on determining the first availability, wherein the queue is a FIFO queue;

determining a second availability of the write buffer;
