Change 3186089 on 2016/11/03 by Mark.Satterthwaite
Duplicate CL #3169764:
Fixed automatic conversion of G8_sRGB into RGBA8_sRGB required for Mac Metal, which fixes FORT-27627.
#jira FORT-27627
Change 3186113 on 2016/11/03 by Mark.Satterthwaite
Duplicate CL #3183807:
Change the way we access the Metal viewport's backbuffer, to reduce possible causes of FORT-31649:
- Added console variable "rhi.Metal.SupportsIntermediateBackBuffer" to control whether to use an extra render-target so we can support screenshots & movie capture, or render directly to the back-buffer to save memory & GPU performance. Still defaults to ON for Mac & OFF for iOS/tvOS.
- Change the way we handle updates to the back-buffer size to ensure that the different threads access their intended version.
#jira FORT-31649
Change 3186116 on 2016/11/03 by Mark.Satterthwaite
Duplicate CL #3183823:
Record Metal resource & state objects used in a command-buffer when rhi.Metal.RuntimeDebugLevel is set to 3 or higher. The object labels, types & descriptions will be printed on failure - if the object is deleted prior to this then we have a lifetime error and it will crash at this point and can be debugged further using our -metalretainrefs command-line option or Xcode's zombie-objects.
Used to verify that FORT-31649 is not a simple resource lifetime error and thereby speed up Apple/vendor investigations.

Change 3209265 on 2016/11/23 by Arne.Schober
DR - originally unshelved from 3153924 - Made Depth and Velocity Rendering Passes to use PSO only RHI interface,
We are now passing down two structs that collect all the necessary information for the drawing policies to construct a PSO object.
One during construction of the Policy, which contains information abouyt the CullMode, FillMode and PrimType.
And another during rendering that passes infomation like BlendState and DepthStencilState down to the low levelrenderer into SetSharedState.
Performance of the static drawlist ist slightly slower (less than 0.1ms on Consoles) due to some addtional branches and copies. The branches in the FDrawingPolicyRenderState will go away as soon as everything is converted to use the PSO interface.
Performace of the GPU is slightly better due to less context rolls (mainly CullMode sorts in differently now)

Changes from UE4-DX12:
*** CL 3183818 ***
Update D3D12 RHI to 4.14:
- Merged changes from Epic up until 10/20/16
- Fixed an issue where command allocators where resetting too early. I changed to aggressive command list batching by default now that more SubmitCommandListHint calls exist in the upper engine, we don't need to worry about starving the GPU. Fewer ExecuteCommandLists calls means better performance and fewer Signals() so this change provides a GPU perf win.
I had to fix an issue with aggressive batching where we would sometimes hold on to a command list long enough (in the pending list) but hadn't executed it yet. The command allocator was being put back in the queue of allocators during ReleaseCommandAllocator() without a syncpoint set and was thus being reset too early. I added a simple counter to the command allocator so it could track how many command lists were using it. It doesn't need to be thread safe since only one thread uses a command allocator at a time.
I also added some stats around the # command lists and # command allocators since it would be possible to leak command allocators now if it's pending command list count isn't decremented correctly. In that case we'd keep creating new command allocators and eventually run out of memory.
-Remove clear during allocate in the FD3D12FastConstantAllocator and FD3D12FastAllocator. The supplied resource locations are assumed to be new and thus don't need to be cleared.
-Cleanup D3D12RHI stats. There were some unused stats as well as some missing ones.
-Mark shader resource table uniform buffers as dirty only when the shader changes. Cleanup SetComputeShader calls and Dispatch calls to not set/unset the CS for each Dispatch.
-Remove unused Check SRV resolved code that epic added to the D3D11 RHI and was brought over. We dont need it and we won't use this.
-Remove "always on" cycle counters for high frequency RHI methods like RHISetShaderTexture. These should use the engine's stat macros as they are removed on TEST + SHIPPING builds. On Xbox a significant amount of CPU time is spent in things like QueryPerformanceCounter even when STATS aren't enabled. Currently 1% of an entire capture on XBOX is spent inside this call.
I improved and cleaned up high freqency call stacks like:
- RHISetShaderTexture
- RHISetShaderResourceViewParameter
- RHISetShaderParameter
- RHISetUAVParameter
In general I moved to use templated functions, removed unused parameters, unnecessary copies, etc.
-Change D3D12 PIX profiling enable/disable to match Xbox and handle logic in the UEBuildWindows.cs for UBT. Also add a static assert to inform the developer when PIX profiling is requested but the engine is compiling out draw events.
-Resources should be associated with the rendering thread's frame that it's currently recording command lists for and they shouldnt be cleaned up until those command lists have been translated to D3D12 command lists on the RHI thread AND completed executing on the GPU. This was confirmed to resolve an issue where CBV resources were being released too early.
This work involved a couple changes:
1) Move the "frame" fence to be incremented on the rendering thread (during RHIAdvanceFrameForGetViewportBackBuffer()) so that resources that are deleted from the rendering thread are assosicated with the correct frame count
2) Queue up a command from the rendering thread to signal the "frame" fence. It needs to be queued to ensure that it's signaled at the correct time on the RHI thread (after that frame's command lists have been executed).
-Disable GRHIRequiresEarlyBackBufferRenderTarget. Metal/Vulkan/Xbox11.x already do this. This is used by the Slate renderer during BeginRenderFrame and avoids a SetRenderTargets call.
-Enable GRHISupportsMSAADepthSampleAccess (used in the Editor). This was enabled for D3D11 on SM5, but not for D3D12.
-Delay load D3D12.dll and add root signature 1.1 support.
-Add explicit flush calls to improve resource barrier batching instead of implict flushes inside FConditionalScopeResourceBarrier and FScopeResourceBarrier. Also update those classes with const members.

Fix the D3D12 RHI after integrating UE 4.14 updates:
- Fixed a bug where we would try to get the PSO of a nullptr in SetPipelineState if we needed to reset the current PSO on the cmd list.
- Fixed a spelling error
- Removed the need for bForceState, we use dirty bits now
*** CL 3183830 ***
- GetDebugFlags RHI extension, needed by XB1 movie player.
- Only query memory info if stats are enabled
- Add support for the engine's new RHISubmitCommandsAndFlushGPU function
- Update CommitPendingPipelineState to be Graphics/Compute specific and avoid the need for a IsCompute parameter.
*** CL 3183837 ***
Made PipelineState caches contain pointers to FD3D12PipelineState objects to avoid issues with using pointers to after Find/Add to the maps. TMap indicates that the pointer to the value associated with a key "is only valid until the next change to any key in the map." The lifetime of the PSO pointers is managed by the low level caches (graphics and compute). Added stat for the number of Pipeline State Objects.
*** CL 3183931 ***
Update Windows D3D12 headers and libs to RS1 release bits (10.0.14393.0)
*** CL 3183978 ***
Update UBT Windows build settings:
- Change D3D12 PIX profiling enable/disable to match Xbox and handle logic in the UEBuildWindows.cs for UBT. Also add a static assert to inform the developer when PIX profiling is requested but the engine is compiling out draw events.
-Delay load D3D12.dll and add root signature 1.1 support.
*** CL 3184132 ***
Fix Xbox PSO cache code where it could leak PSOs. Related to change 3183837.
*** Changelist 3211714 ***
Update D3D12 RHI with fixes:
- Check if we can reserve slots in GatherUniqueSamplerTables
- DirtyState more often in StateCache
- Remove InternalSetSamplerState. The alternate function isn't used.
- Allow MRTClear for arrays with holes in them
- Fix uninitialized descriptors. This was causing a GPU hang on Xbox. We need to set dirty bits for resources bound to slots outside of the current descriptor table's range
- Cleanup SetDescriptorHeap code. Move setting descriptor heap logic to the descriptor cache since it also owns things like the sampler maps. Added members to the descriptor cache to track the last heaps that were set on the command list to avoid dirtying bit unnecessarily.
- Resource transitions: go through Common between queues (3D <--> Compute)
- Fix initial state for placed resources.
- Merging epic
