From 12f2eae7e7e74c1c3f16fee1f27eec6cfcffe092 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Wed, 23 Nov 2016 19:26:13 -0800 Subject: [PATCH] intel/aubinator: Trust the packet size in the header for SUBOPCODE_HEADER We were reading from the "comment size" dword and incrementing by that amount. This never caused a problem because that field was always zero. However, experimenting with actual aub file comments indicates, the simulator seems to include the comment size in the packet size provided in the header. We should do the same.
