From f43897e51e51824bfd7c26bf54cbbdd7ddb24f2b Mon Sep 17 00:00:00 2001 From: foreman Date: Fri, 28 Nov 2014 18:11:36 -0500 Subject: [PATCH] P4 to Git Change 1101352 by gandryey@gera-dev-w7 on 2014/11/28 18:03:18 ECR #304775 - Make optimization for read map of USWC memory - If runtime detects USWC map with read operation, then it will switch to indirect map. This should improve map-read performance on APU(s) when USWC memory is used instead of frame buffer Affected files ... ... //depot/stg/opencl/drivers/opencl/api/opencl/amdocl/cl_memobj.cpp#72 edit ... //depot/stg/opencl/drivers/opencl/api/opencl/amdocl/cl_svm.cpp#8 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/cpu/cpudevice.cpp#269 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/cpu/cpudevice.hpp#89 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/device.cpp#172 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/device.hpp#234 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/gpu/gpudevice.cpp#486 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/gpu/gpudevice.hpp#134 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/gpu/gpumemory.cpp#112 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/gpu/gpumemory.hpp#43 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/gpu/gpuvirtual.cpp#340 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/hsa/hsadevice.cpp#88 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/hsa/hsadevice.hpp#45 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/hsa/hsamemory.cpp#42 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/hsa/hsamemory.hpp#27 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/hsa/hsavirtual.cpp#98 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/hsa_foundation/hsadevice.cpp#21 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/hsa_foundation/hsadevice.hpp#7 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/hsa_foundation/hsamemory.cpp#6 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/hsa_foundation/hsamemory.hpp#5 edit ... //depot/stg/opencl/drivers/opencl/runtime/device/hsa_foundation/hsavirtual.cpp#26 edit [ROCm/clr commit: 6d464be2522e6b2bb1c97c30b57b21c2c4244935] --- .../rocclr/runtime/device/cpu/cpudevice.cpp | 1 + .../rocclr/runtime/device/cpu/cpudevice.hpp | 1 + projects/clr/rocclr/runtime/device/device.cpp | 16 ++-- projects/clr/rocclr/runtime/device/device.hpp | 14 +++- .../rocclr/runtime/device/gpu/gpudevice.cpp | 3 +- .../rocclr/runtime/device/gpu/gpudevice.hpp | 2 + .../rocclr/runtime/device/gpu/gpumemory.cpp | 8 +- .../rocclr/runtime/device/gpu/gpumemory.hpp | 2 + .../rocclr/runtime/device/gpu/gpuvirtual.cpp | 75 +++++++------------ .../rocclr/runtime/device/hsa/hsadevice.cpp | 3 +- .../rocclr/runtime/device/hsa/hsadevice.hpp | 2 + .../rocclr/runtime/device/hsa/hsamemory.cpp | 4 +- .../rocclr/runtime/device/hsa/hsamemory.hpp | 2 + .../rocclr/runtime/device/hsa/hsavirtual.cpp | 7 +- 14 files changed, 75 insertions(+), 65 deletions(-) diff --git a/projects/clr/rocclr/runtime/device/cpu/cpudevice.cpp b/projects/clr/rocclr/runtime/device/cpu/cpudevice.cpp index bf39c6a7dd..d871cff32e 100644 --- a/projects/clr/rocclr/runtime/device/cpu/cpudevice.cpp +++ b/projects/clr/rocclr/runtime/device/cpu/cpudevice.cpp @@ -1123,6 +1123,7 @@ Device::allocMapTarget( amd::Memory& mem, const amd::Coord3D& origin, const amd::Coord3D& region, + uint mapFlags, size_t* rowPitch, size_t* slicePitch) { diff --git a/projects/clr/rocclr/runtime/device/cpu/cpudevice.hpp b/projects/clr/rocclr/runtime/device/cpu/cpudevice.hpp index e52db18615..03dd1a8e12 100644 --- a/projects/clr/rocclr/runtime/device/cpu/cpudevice.hpp +++ b/projects/clr/rocclr/runtime/device/cpu/cpudevice.hpp @@ -143,6 +143,7 @@ public: amd::Memory& mem, //!< Abstraction layer memory object const amd::Coord3D& origin, //!< The map location in memory const amd::Coord3D& region, //!< The map region in memory + uint mapFlags, //!< Map flags size_t* rowPitch = NULL, //!< Row pitch for the mapped memory size_t* slicePitch = NULL //!< Slice for the mapped memory ); diff --git a/projects/clr/rocclr/runtime/device/device.cpp b/projects/clr/rocclr/runtime/device/device.cpp index 1cd452828e..f152a0fd8d 100644 --- a/projects/clr/rocclr/runtime/device/device.cpp +++ b/projects/clr/rocclr/runtime/device/device.cpp @@ -572,15 +572,21 @@ Kernel::~Kernel() } void -Memory::saveWriteMapInfo( +Memory::saveMapInfo( const amd::Coord3D origin, const amd::Coord3D region, + uint mapFlags, bool entire) { - writeMapInfo_.origin_ = origin; - writeMapInfo_.region_ = region; - writeMapInfo_.entire_ = entire; - flags_ |= UnmapWrite; + if (mapFlags & (CL_MAP_WRITE | CL_MAP_WRITE_INVALIDATE_REGION)) { + writeMapInfo_.origin_ = origin; + writeMapInfo_.region_ = region; + writeMapInfo_.entire_ = entire; + flags_ |= UnmapWrite; + } + if (mapFlags & CL_MAP_READ) { + flags_ |= UnmapRead; + } } Program::Program(amd::Device& device) diff --git a/projects/clr/rocclr/runtime/device/device.hpp b/projects/clr/rocclr/runtime/device/device.hpp index c427ba2cfc..2eb8027789 100644 --- a/projects/clr/rocclr/runtime/device/device.hpp +++ b/projects/clr/rocclr/runtime/device/device.hpp @@ -727,20 +727,24 @@ public: //!
