Thanks Jani for taking the time to review... 1. apologies on the const issue, this is my bad, i think it was one of the comments from earlier rev not sure how i missed it. Will fix this on next rev. 2. I do have a question below on the const for one of specific types of tables.

I had a question though... the list of registers like the one above as well as below shall be made const... however, the table-of-lists (see farther down), contains a pointer to "extended_regs" that shall be allocated at startup - is it okay for that list to remain non-const since the others with actual register offsets remain const? Alan: will add const for this and above tables: static struct __guc_mmio_reg_descr xe_lpd_global_regs[] = { COMMON_BASE_GLOBAL(), COMMON_GEN9BASE_GLOBAL(), COMMON_GEN12BASE_GLOBAL(), }; Is this okay to not be const?: static struct __guc_mmio_reg_descr_group default_lists[] = { MAKE_REGLIST(default_global_regs, PF, GLOBAL, 0), MAKE_REGLIST(default_rc_class_regs, PF, ENGINE_CLASS, GUC_RENDER_CLASS), MAKE_REGLIST(xe_lpd_rc_inst_regs, PF, ENGINE_INSTANCE, GUC_RENDER_CLASS), MAKE_REGLIST(empty_regs_list, PF, ENGINE_CLASS, GUC_VIDEO_CLASS), MAKE_REGLIST(xe_lpd_vd_inst_regs, PF, ENGINE_INSTANCE, GUC_VIDEO_CLASS), MAKE_REGLIST(empty_regs_list, PF, ENGINE_CLASS, GUC_VIDEOENHANCE_CLASS), MAKE_REGLIST(xe_lpd_vec_inst_regs, PF, ENGINE_INSTANCE, GUC_VIDEOENHANCE_CLASS), MAKE_REGLIST(empty_regs_list, PF, ENGINE_CLASS, GUC_BLITTER_CLASS), MAKE_REGLIST(xe_lpd_blt_inst_regs, PF, ENGINE_INSTANCE, GUC_BLITTER_CLASS), {} };
