| The migration work is to rewrite the OpKernel implementation of the corresponding heterogeneous device or third-party library originally implemented in the `paddle/fluid/operators` directory into a functional Kernel in the form of PHI Kernel, and place it in the `paddle/phi/kernels` directory or the kernels directory of the external CustomDevice repo. Specifically, taking `log_softmax` Op as an example, for different device backends, the objects to be migrated and their placement positions are as follows: | ||
|
|
||
| - XPU: `paddle/fluid/operators/log_softmax_op_xpu.cc` modified and migrated to `paddle/phi/kernels/xpu/log_softmax_kernel.cc & log_softmax_grad_kernel.cc` | ||
| - MKLDNN: `paddle/fluid/operators/mkldnn/`log_softmax_mkldnn_op`.cc` modified and migrated to `paddle/phi/kernels/onednn/log_softmax_kernel.cc` |

log_softmax_mkldnn_op.cc，是不是多加了引号

| Secondly, it is necessary to replace some of the types or functions that were only used in fluid in the original function implementation with the corresponding types or functions in PHI. The mapping relationship of some replacements are as follows: | ||
