Added vendor hook to consider ufs host/device perf heuristic and error recovery according to different platform/design Vendor/Platform can take necessary action according to their design/implementation Added vendor hook before calling UFS command ops - trace_android_vh_ufs_perf_huristic_ctrl Added vendor hook after sending UFS command to host - trace_android_vh_ufs_send_command_post_change Added vendor hook for abort success case - trace_android_vh_ufs_abort_success_ctrl Added vendor hook for completion response check - trace_android_vh_ufs_compl_rsp_check_done Added vendor hook for vendor specific error handling - trace_android_vh_ufs_err_handler Added vendor hook for err logs printing control - trace_android_vh_ufs_err_print_ctrl Added vendor hook for error checking flow trigger - trace_android_vh_ufs_err_check_ctrl Bug: 312806167 Change-Id: I2190afe62b60da9d47001307f858f10fc8a59986 Signed-off-by: Sanjeev Yadav <sanjeev.y@mediatek.com> Signed-off-by: Browse Zhang <browse.zhang@mediatek.com>
