From 3fee20dfecfc7fbcc3a013d1faf70e69f7324616 Mon Sep 17 00:00:00 2001 From: Philip Rebohle Date: Fri, 3 Aug 2018 11:10:40 +0200 Subject: [PATCH] [d3d11] Implement DiscardResource for buffers We don't suppor this for images, and we don't support DiscardView yet. Buffers can be invalidated, which may in some cases be beneficial in order to avoid synchronization on the GPU. --- src/d3d11/d3d11_context.cpp | 33 +++++++++++++++++++++++---------- src/d3d11/d3d11_context.h | 3 +++ src/d3d11/d3d11_device.cpp | 2 +- 3 files changed, 27 insertions(+), 11 deletions(-) diff --git a/src/d3d11/d3d11_context.cpp b/src/d3d11/d3d11_context.cpp index 8dc5fcc0..6c70ef4e 100644 --- a/src/d3d11/d3d11_context.cpp +++ b/src/d3d11/d3d11_context.cpp @@ -61,20 +61,24 @@ namespace dxvk { return E_NOINTERFACE; } - void STDMETHODCALLTYPE D3D11DeviceContext::DiscardResource(ID3D11Resource * pResource) { - static bool s_errorShown = false; - - if (!std::exchange(s_errorShown, true)) - Logger::err("D3D11DeviceContext::DiscardResource: Not implemented"); + + void STDMETHODCALLTYPE D3D11DeviceContext::DiscardResource(ID3D11Resource* pResource) { + D3D11_RESOURCE_DIMENSION resType = D3D11_RESOURCE_DIMENSION_UNKNOWN; + pResource->GetType(&resType); + + // We don't support the Discard API for images + if (resType == D3D11_RESOURCE_DIMENSION_BUFFER) + DiscardBuffer(reinterpret_cast(pResource)); } - void STDMETHODCALLTYPE D3D11DeviceContext::DiscardView(ID3D11View * pResourceView) { - static bool s_errorShown = false; - - if (!std::exchange(s_errorShown, true)) - Logger::err("D3D11DeviceContext::DiscardView: Not implemented"); + + void STDMETHODCALLTYPE D3D11DeviceContext::DiscardView(ID3D11View* pResourceView) { + // Ignore.
