From fa906a888ba908611086e5e80a19bbb99618945d Mon Sep 17 00:00:00 2001 From: Xavi Zhang Date: Tue, 1 Mar 2016 03:40:15 -0500 Subject: [PATCH] amdgpu/addrlib: add matchStencilTileCfg and tcCompatible fixes The usage should be client first call AddrComputeSurfaceInfo() on depth surface with flag "matchStencilTilecfg", AddrLib will use 2DThin1 tile index for depth as much as possible and do not down grade unless alignment requirement cannot be met. 1. If there is a matched 2DThin1 tile index for stencil which make sure they will share same tile config parameters, then return the stencil 2DThin1 tile index as well. 2. If using 2DThin1 tile mode cannot make sure such thing happen, and TcCompatible flag was set, then ignore this flag then try 2DThin1 tile mode for depth and stencil again. 3. If 2DThin1 tile mode cannot make sure depth and stencil to have same tile config parameters, then down grade depth surface tile mode to 1DThin1. 4. If depth surface's tile mode was 1DThin1, then return 1DThin1 tile index for stencil. 5. If depth surface's tile mode is PRT, then return invalid tile index to stencil since their tile config parameters will never be met. Client driver then check the returned tile index of stencil -- if it is not invalid tile index, then call AddrComputeSurfaceInfo() on stencil surface with the returned stencil tile index to get full output information. Please note, client needs to set flag "useTileIndex" when AddrLib get created. --- src/amd/addrlib/addrinterface.h | 6 +- src/amd/addrlib/core/addrlib1.cpp | 19 ++-- src/amd/addrlib/r800/ciaddrlib.cpp | 140 ++++++++++++++++++++++++++--- src/amd/addrlib/r800/ciaddrlib.h | 7 ++ 4 files changed, 152 insertions(+), 20 deletions(-) diff --git a/src/amd/addrlib/addrinterface.h b/src/amd/addrlib/addrinterface.h index c68cacf0952..2a61b2b33f2 100644 --- a/src/amd/addrlib/addrinterface.h +++ b/src/amd/addrlib/addrinterface.h @@ -519,7 +519,9 @@ typedef union _ADDR_SURFACE_FLAGS UINT_32 rotateDisplay : 1;
