1. A method for utilizing a data processing unit (DPU), comprising:

identifying, by the DPU, a processing entity operatively connected to the DPU;

receiving processing entity properties from the processing entity;

storing the processing entity properties in a processing entity catalog;

generating a virtual combined memory space in the processing entity catalog, wherein generating the virtual combined memory space in the processing entity catalog comprises:

identifying processing entity memory properties in the processing entity properties; and

in response to identifying the processing entity memory properties:

allocating a DPU virtual memory space for a memory of the processing entity, and

associating the DPU virtual memory space with the memory of the processing entity; and

providing access to the processing entity catalog to a BIOS.

2. The method of claim 1 , wherein after providing access to the processing entity catalog to the BIOS, the method further comprises:

receiving a copy of the processing entity catalog;

comparing the processing entity catalog to the copy of the processing entity catalog;

identifying, based on the comparing, a difference in the copy of the processing entity catalog; and

configuring, based on the difference, the processing entity.

3. The method of claim 2 , wherein configuring the processing entity comprises:

sending a command to the processing entity, wherein the command comprises:

instructions to modify a setting of the processing entity; and

receiving a confirmation, from the processing entity, that the setting of the processing entity was modified.

4. The method of claim 3 , wherein after receiving the confirmation, the method further comprises:

updating the processing entity catalog to include the difference; and

providing access to the processing entity catalog to the BIOS.

5. The method of claim 2 ,

wherein providing access to the processing entity catalog to the BIOS comprises:

creating the copy of the processing entity catalog in a shared memory, and

wherein receiving the copy of the processing entity catalog comprises:

identifying that the copy of the processing entity catalog has been modified.

6. The method of claim 1 , wherein after providing access to the processing entity catalog to the BIOS, the method further comprises:

receiving a write request, comprising:

a virtual memory address; and

data;

matching the virtual memory address with the memory of the processing entity; and

writing the data to the memory of the processing entity.

7. The method of claim 6 , wherein matching the virtual memory address with the memory of the processing entity comprises:

identifying, in the virtual combined memory space, the DPU virtual memory space that includes the virtual memory address; and

identifying a physical memory address associated with the virtual memory address, wherein the physical memory address is located on the memory of the processing entity.

8. A non-transitory computer readable medium comprising instructions which, when executed by a computer processor, enables the computer processor to perform a method for utilizing a data processing unit (DPU), comprising:

identifying, by the DPU, a processing entity operatively connected to the DPU;

receiving processing entity properties from the processing entity;

storing the processing entity properties in a processing entity catalog;

generating a virtual combined memory space in the processing entity catalog; providing access to the processing entity catalog to a BIOS;

wherein after providing access to the processing entity catalog to the BIOS:

receiving a copy of the processing entity catalog;

comparing the processing entity catalog to the copy of the processing entity catalog;

identifying, based on the comparing, a difference in the copy of the processing entity catalog; and

configuring, based on the difference, the processing entity.

9. The non-transitory computer readable medium of claim 8 , wherein configuring the processing entity comprises:

sending a command to the processing entity, wherein the command comprises: instructions to modify a setting of the processing entity; and

receiving a confirmation, from the processing entity, that the setting of the processing entity was modified.

10. The non-transitory computer readable medium of claim 9 , wherein after receiving the confirmation, the method further comprises:

updating the processing entity catalog to include the difference; and

providing access to the processing entity catalog to the BIOS.

11. The non-transitory computer readable medium of claim 8 ,

wherein providing access to the processing entity catalog to the BIOS comprises:

creating the copy of the processing entity catalog in a shared memory, and

wherein receiving the copy of the processing entity catalog comprises:

identifying that the copy of the processing entity catalog has been modified.

12. The non-transitory computer readable medium of claim 8 , wherein generating the virtual combined memory space in the processing entity catalog comprises:

identifying processing entity memory properties in the processing entity properties; and

in response to identifying the processing entity memory properties:

allocating a DPU virtual memory space for a memory of the processing entity; and

associating the DPU virtual memory space with the memory of the processing entity.

13. The non-transitory computer readable medium of claim 12 , wherein after providing access to the processing entity catalog to the BIOS, the method further comprises:

receiving a write request, comprising:

a virtual memory address; and

data;

matching the virtual memory address with the memory of the processing entity; and

writing the data to the memory of the processing entity.

14. The non-transitory computer readable medium of claim 13 , wherein matching the virtual memory address with the memory of the processing entity comprises:

identifying, in the virtual combined memory space, the DPU virtual memory space that includes the virtual memory address; and

identifying a physical memory address associated with the virtual memory address, wherein the physical memory address is located on the memory of the processing entity.

15. A node, comprising:

data processing unit (DPU); and

a processor, wherein the processor is configured to perform a method for utilizing the DPU, comprising:

identifying, by the DPU, a processing entity operatively connected to the DPU;
