I think the comment should reflect the usage not just follow the same name of the registe #define - else why even add the comments. (please apply this same comment for gen8_vd_inst_regs, gen8_vec_inst_regs and gen8_blt_inst_regs). alternatively, we could keep those GEN8+ comments above the list but maybe add just one comment in the default list - see below. </pre> </blockquote> Because at some point we might want to start supporting other platforms. My view is that the comment should be accurate. These registers exist on Gen8+. So if you are building a register list for a Gen8 or later device, they can/should be included. <blockquote type="cite" cite="mid:9e0711a1e40cdeccdf6ae003e924dfec5cdbb77b.camel@intel.com"> <pre class="moz-quote-pre" wrap="">alan: snip </pre> <blockquote type="cite"> <pre class="moz-quote-pre" wrap="">@@ -366,7 +364,7 @@ guc_capture_get_device_reglist(struct intel_guc *guc) const struct __guc_mmio_reg_descr_group *lists; if (GRAPHICS_VER(i915) >= 12) - lists = xe_lpd_lists; + lists = xe_lp_lists; else lists = default_lists; </pre> </blockquote> <pre class="moz-quote-pre" wrap="">alan: perhaps add a comment that we really don't support any of this on anything below Gen9?</pre> </blockquote> It wasn't me that named it 'default_' rather than gen9_.
