HIP09 supports larger entries/contexts to improve the performance of bus or exchange more information with the hardware. The capbilities changes from HIP08 to HIP09 is as follows: - CEQE: 4B -> 64B - AEQE: 16B -> 64B - CQE: 32B -> 64B - QPC: 256B -> 512B - SCCC: 32B -> 64B Previous discussions can be found at: v3: https://patchwork.kernel.org/cover/11753687/ v2: https://patchwork.kernel.org/cover/11726269/ v1: https://patchwork.kernel.org/cover/11718143/ Changes since v3: - Fix comments from Jason in #2 about the length of buffer to copy. Changes since v2: - Fix comments from Jason about passing cap_flags to the userspace and drop #1 from this series. - Add a new patch to support SCCC in size of 64 Bytes. Changes since v1: - Fix comments from Lang Cheng about redundant comments and type of reserved fields in structure of eqe. - Rename some variables.
