From 42f421cbbfcdadd29543246191697a12f0461e40 Mon Sep 17 00:00:00 2001 From: Scott D Phillips Date: Tue, 28 Nov 2017 15:52:10 -0800 Subject: [PATCH] aubinator: add support for aubinating memtrace aubs Memtrace aubs are similar to classic aubs, with the major difference being how command submission is serialized (as register writes instead of a high-level submit message). Some internal tools generate or consume only memtrace aubs.
