From ff64c3951a1daff33d7c66058bb7c4edbb162fbf Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Fri, 29 Nov 2019 16:51:14 -0300 Subject: texture_cache/surface_base: Fix out of bounds texture views Some texture views were being created out of bounds (with more layers or mipmaps than what the original texture has). This is because of a miscalculation in mipmap bounding. end_layer and end_mipmap are out of bounds (e.g. layer 6 in a cubemap), there's no need to add one more there. Fixes OpenGL errors and Vulkan crashes on Splatoon 2. --- src/video_core/texture_cache/surface_base.h | 11 ++++------- 1 file changed, 4 insertions(+), 7 deletions(-) (limited to 'src/video_core') diff --git a/src/video_core/texture_cache/surface_base.h b/src/video_core/texture_cache/surface_base.h index 1bed82898..5f79bb0aa 100644 --- a/src/video_core/texture_cache/surface_base.h +++ b/src/video_core/texture_cache/surface_base.h @@ -254,16 +254,14 @@ public: if (!layer_mipmap) { return {}; } - const u32 end_layer{layer_mipmap->first}; - const u32 end_mipmap{layer_mipmap->second}; + const auto [end_layer, end_mipmap] = *layer_mipmap; if (layer != end_layer) { if (mipmap == 0 && end_mipmap == 0) { - return GetView(ViewParams(view_params.target, layer, end_layer - layer + 1, 0, 1)); + return GetView(ViewParams(view_params.target, layer, end_layer - layer, 0, 1)); } return {}; } else { - return GetView( - ViewParams(view_params.target, layer, 1, mipmap, end_mipmap - mipmap + 1)); + return GetView(ViewParams(view_params.target, layer, 1, mipmap, end_mipmap - mipmap)); } } @@ -278,8 +276,7 @@ public: if (!layer_mipmap) { return {}; } - const u32 layer{layer_mipmap->first}; - const u32 mipmap{layer_mipmap->second}; + const auto [layer, mipmap] = *layer_mipmap; if (GetMipmapSize(mipmap) != candidate_size) { return EmplaceIrregularView(view_params, view_addr, candidate_size, mipmap, layer); } -- cgit v1.2.3
