2018-4-16 update

  • Reduce unnecessary malloc/free calls
  • [LLPC] Change the undef value to 0 or 0.0 for those unsupported functions. This is because undef value will block constant folding in LLVM and the nested constant expression after lower will be time-consuming when backend does analysis
  • [LLPC] Support int64 atomic operations
  • Tweaks the way tha handles load op clears in renderpasses to fix too many barriers in render pass clear
  • Add error handling where AddMemReference() is used; Add vk::Memory::CreateGpuMemory() and vk::Memory::CreateGpuPinnedMemory()
  • Fix assertion when running DOOM 2016 in Wine
  • Set "vm" flag for all fragment outputs
  • Add FMASK shadow table support to the Vulkan Driver which changes descriptors are stored in memory. This allows writing the FMASK descriptors in the same corresponding upper 32 bits of the STA descriptors VA address
  • Fix missing cmd scratch memory heap in gpasession. Prevents a divide by zero exception when initializing driver for RGP traces
  • Explicitly acquire and release ownership of the queue context in PAL's preamble and postamble command streams
  • PAL no longer try to chain from the last command buffer to the postamble command streams.*
  • Fix interfaceLogger access violation. DataAllocNames array does not match CmdAllocType enum.
  • VK_AMD_gpu_shader_int16 + VK_AMD_shader_trinary_minmax + GFX9: Graphics pipeline fails to create if functionality dependent on the two exts is used
  • Rewrite VamMgrSingleton to avoid static members
  • Clean-Up of User Data Table Management Code

2018-4-9 update

  • Add int16 support to AMD_shader_ballot and AMD_trinary_minmax extension
  • [LLPC] Enable RetBlock in GS to make sure only one return is used in GS
  • Refine Pipeline dump
    • Simplify pipeline panel options
    • Update variable name in llpcAbiMetadata.h to match palPipelineAbi original name
    • Remove metadata name in RegNameMap, instead, Util::Abi::PipelineMetadataNameStrings is used
    • Fix a bug in PipelineCompiler::ApplyBilConvertOptions, the return value of GetRuntimeSettings must be a reference
  • AMD_shader_ballot:
    • Rename glslSpecialOpEmuF16 to glslSpecialOpEmuD16
    • Add stubs of subgroup arithmetic operations for i64 and f16
    • use tbuffer_load_d16 to do vertex fetching
  • Implement a consistent dispatch table mechanism across the driver
    • Now we have separate global, per-instance, and per-device dispatch tables
    • We can override individual entry points in each dispatch table to enable optimizations based on app profile or any other criteria
    • Entry points now can have complex requirement criteria and we now clearly distinguish between instance and device level functions
    • SQTT layer handling is still a bit clumsy because it operates more like a device-only layer, but at least it's injection code is less intrusive now
    • Also fixed a bunch of unrelated bugs and missing implementation on the way, as the new code revealed those
  • Update Pipeline Dump service to inherit from IService instead of URIService (which is deprecated and being removed).
  • Changes ValidateDraw to reserve its own space rather than including it with the rest of the draw related packets. This avoids running out of reserved space in TimeSpy
  • Move MetroHash and jemalloc to pal/src/util/imported from pal/src/core/imported

  • Implement subgroup arithmetic reduce int ops
  • Remove KHR suffixes for promoted extensions: replace some of the KHXs with KHRs, the rest should go away whenever device group KHXs are removed
  • Remove Vulkan 1.0 headers because 1.1's are backward compatible, 1.0 driver functionality can still be built with USE_NEXT_SDK=0
  • Fix an issue that incorrect buffer causes compute shader loop infinitely
  • Disable FmaskBasedMsaaRead for Dota2, which can bring ~1% performance gain for Dota2 4K + best-looking on Fiji:

  • Fix bug in PA_SC_MODE_CNTL_1 validation
  • Improve hotspots related to Color-Target & Depth/Stencil views, some improvements in CPU performance when creating color-target and depth-stencil view objects in PAL
  • Make GFX9's BuildSetSeqContextRegs() and BuildSetSeqConfigRegs() avoid reading from the command buffer similar to what is done for GFX6. Cleans up big spikes if Vulkan uses write combined command buffers (they were small bumps when using cacheable command buffers)
