From f20895358525f3a8abaefe3a5c2ebe7d30eadc78 Mon Sep 17 00:00:00 2001 From: Subv Date: Mon, 23 Apr 2018 17:06:57 -0500 Subject: GPU: Added asserts to our code for handling the QUERY_GET GPU command. This is based on research from nouveau. Many things are currently unknown and will require hwtests in the future. This commit also stubs QueryMode::Write2 to do the same as Write. Nouveau code treats them interchangeably, it is currently unknown what the difference is. --- src/video_core/engines/maxwell_3d.cpp | 27 ++++++++++++++++++++++++++- 1 file changed, 26 insertions(+), 1 deletion(-) (limited to 'src/video_core/engines/maxwell_3d.cpp') diff --git a/src/video_core/engines/maxwell_3d.cpp b/src/video_core/engines/maxwell_3d.cpp index 2a3ff234a..35773a695 100644 --- a/src/video_core/engines/maxwell_3d.cpp +++ b/src/video_core/engines/maxwell_3d.cpp @@ -147,11 +147,36 @@ void Maxwell3D::ProcessQueryGet() { // VAddr before writing.
