Adding to the list: * ACA, mentionned in debug_mask flags - digging the source shows it seems to be "Accelerator Check Architecture", but maybe some additional details could be added? * DPIA (likely for dc-glossary): listed in DC_DEBUG_MASK values, source code in several places shows "DisplayPort Input Adapter", but maybe more details would be useful here too? Often associated with DP USB4 tunneling in source code.
