31  * indirect H2G data to GuC without a need to create a ad-hoc allocation.
67  * xe_guc_buf_reserve() - Reserve a new sub-allocation.
68  * @cache: the &xe_guc_buf_cache where reserve sub-allocation
72  * Must use xe_guc_buf_release() to release a sub-allocation.
74  * Return: a &xe_guc_buf of new sub-allocation.
89  * xe_guc_buf_from_data() - Reserve a new sub-allocation using data.
90  * @cache: the &xe_guc_buf_cache where reserve sub-allocation
91  * @data: the data to flush the sub-allocation
96  * Return: a &xe_guc_buf of new sub-allocation.
111  * xe_guc_buf_release() - Release a sub-allocation.
114  * Releases a sub-allocation reserved by the xe_guc_buf_reserve().
123  * xe_guc_buf_flush() - Copy the data from the sub-allocation to the GPU memory.
126  * Return: a GPU address of the sub-allocation.
135  * xe_guc_buf_cpu_ptr() - Obtain a CPU pointer to the sub-allocation.
138  * Return: a CPU pointer of the sub-allocation.
146  * xe_guc_buf_gpu_addr() - Obtain a GPU address of the sub-allocation.
149  * Return: a GPU address of the sub-allocation.
159  * @ptr: the CPU pointer of the sub-allocation
