/**
* Test specification for: test_engine_status
*
* Description: Engine status helper functions
*
* Test Type: Feature based
*
* Targets: nvgpu_engine_status_is_ctxsw_switch,
* nvgpu_engine_status_is_ctxsw_load,
* nvgpu_engine_status_is_ctxsw_save,
* nvgpu_engine_status_is_ctxsw,
* nvgpu_engine_status_is_ctxsw_invalid,
* nvgpu_engine_status_is_ctxsw_valid,
* nvgpu_engine_status_is_ctx_type_tsg,
* nvgpu_engine_status_is_next_ctx_type_tsg
*
* Input: None
*
* Steps:
* - Initialize ctxsw_status field of nvgpu_engine_status_info structure with
* with NVGPU_CTX_STATUS_INVALID, NVGPU_CTX_STATUS_VALID,
* NVGPU_CTX_STATUS_CTXSW_LOAD, NVGPU_CTX_STATUS_CTXSW_SAVE,
* NVGPU_CTX_STATUS_CTXSW_SWITCH, and U32(~0).
* - Check that nvgpu_engine_status_is_ctxsw_load,
* nvgpu_engine_status_is_ctxsw_save, nvgpu_engine_status_is_ctxsw,
* nvgpu_engine_status_is_ctxsw_invalid, nvgpu_engine_status_is_ctxsw_valid,
* return consistent values.
* - Initialize ctx_id with a counter and ctx_id_types successively with
* ENGINE_STATUS_CTX_ID_TYPE_CHID, ENGINE_STATUS_CTX_ID_TYPE_TSGID, and
* ENGINE_STATUS_CTX_ID_TYPE_INVALID.
* - Initialize next_ctx_id and next_ctx_id_types with invalid values
* (to make sure accessors use the right fields).
* - Check that nvgpu_engine_status_is_ctx_type_tsg and
* nvgpu_engine_status_get_ctx_id_type return consitent values.
* - Use same method to check nvgpu_engine_status_is_next_ctx_type_tsg and
* nvgpu_engine_status_get_next_ctx_id_type.
*
* Output: Returns PASS if all branches gave expected results. FAIL otherwise.
