Unable to Read/Write AIE2 Registers – Missing aie2_internal.h

[ngdxzy]

Description:

I am attempting to read and write to the registers in the NPU (AIE2), but I encounter an error indicating that the operation is not supported.

Upon investigating the source code (aie2_pci.c), I found that the aie2_read_aie_reg operation is not compiled because AMDXDNA_AIE2_PRIV is not set. After enabling AMDXDNA_AIE2_PRIV in the Makefile, I encountered another issue: the header file aie2_internal.h is missing from the repository.

Could you clarify whether this file is considered confidential or if it has simply not been released yet?

Steps to Reproduce:

1.	Attempt to read/write AIE2 registers.
2.	Encounter an error stating the operation is not supported.
3.	Check aie2_pci.c and notice aie2_read_aie_reg is not compiled.
4.	Set AMDXDNA_AIE2_PRIV in the Makefile.
5.	Compilation fails due to missing aie2_internal.h.

Questions:

• Is aie2_internal.h an internal/confidential file?
• If not, will it be made available in a future release?

Any guidance on this issue would be greatly appreciated. Thank you!
