From be660e77490b65d004a77d47bca1c443eb15482c Mon Sep 17 00:00:00 2001 From: Morph <39850852+Morph1984@users.noreply.github.com> Date: Thu, 18 Jun 2020 04:42:40 -0400 Subject: [PATCH] maxwell_to_vk: Reorder filter cases and correct mipmap_filter=None maxwell_to_vk: Reorder filtering modes to start with None, then Nearest, then Linear. maxwell_to_vk: Logs filter modes under UNREACHABLE_MSG instead of UNIMPLEMENTED_MSG, since any unknown filter modes are invalid and not unimplemented. maxwell_to_vk: Return VK_SAMPLER_MIPMAP_MODE_NEAREST instead of VK_SAMPLER_MIPMAP_MODE_LINEAR when mipmap_filter is None with the description from the VkSamplerCreateInfo(3) man page. --- .../renderer_vulkan/maxwell_to_vk.cpp | 32 +++++++++---------- 1 file changed, 15 insertions(+), 17 deletions(-) diff --git a/src/video_core/renderer_vulkan/maxwell_to_vk.cpp b/src/video_core/renderer_vulkan/maxwell_to_vk.cpp index 62e950d310..1f2b6734ba 100644 --- a/src/video_core/renderer_vulkan/maxwell_to_vk.cpp +++ b/src/video_core/renderer_vulkan/maxwell_to_vk.cpp @@ -21,29 +21,29 @@ namespace Sampler { VkFilter Filter(Tegra::Texture::TextureFilter filter) { switch (filter) { - case Tegra::Texture::TextureFilter::Linear: - return VK_FILTER_LINEAR; case Tegra::Texture::TextureFilter::Nearest: return VK_FILTER_NEAREST; + case Tegra::Texture::TextureFilter::Linear: + return VK_FILTER_LINEAR; } - UNIMPLEMENTED_MSG("Unimplemented sampler filter={}", static_cast(filter)); + UNREACHABLE_MSG("Invalid sampler filter={}", static_cast(filter)); return {}; } VkSamplerMipmapMode MipmapMode(Tegra::Texture::TextureMipmapFilter mipmap_filter) { switch (mipmap_filter) { case Tegra::Texture::TextureMipmapFilter::None: - // TODO(Rodrigo): None seems to be mapped to OpenGL's mag and min filters without mipmapping - // (e.g. GL_NEAREST and GL_LINEAR).
