[Fix] Enable GPU frequeencey boost on Alderlake P platforms. [Test Plan] I've run verified that the GPU performance increases with these patches, and I've done various other GPU testing to make limit any regressions. My testing yeilded 3.5 GFlops to 42.6 Gflops for the matrix_multiply test. ubuntu@adl-p:~/gfx/test$ ./matrix_multiply Running on device: Intel(R) Graphics [0x46a6] Success! GFlops: 3.51592 ubuntu@adl-p:~/gfx/test$ ubuntu@adl-p:~/gfx/test$ ./matrix_multiply Running on device: Intel(R) Graphics [0x46a6] Success! GFlops: 42.6402 ubuntu@adl-p:~/gfx/test$ [Where problems could occur] The patch is fairly narrow, but I have ran the code through numerous benchmarks, and QA tests, as well as ad hoc testing to minimize any regressions we may see.
