From 258487370fd840b018a404225277d74f74899c59 Mon Sep 17 00:00:00 2001 From: Niklas Haas Date: Wed, 13 Sep 2017 03:09:48 +0200 Subject: vo_gpu: vulkan: generalize SPIR-V compiler In addition to the built-in nvidia compiler, we now also support a backend based on libshaderc. shaderc is sort of like glslang except it has a C API and is available as a dynamic library. The generated SPIR-V is now cached alongside the VkPipeline in the cached_program. We use a special cache header to ensure validity of this cache before passing it blindly to the vulkan implementation, since passing invalid SPIR-V can cause all sorts of nasty things. It's also designed to self-invalidate if the compiler gets better, by offering a catch-all `int compiler_version` that implementations can use as a cache invalidation marker. --- video/out/vulkan/common.h | 1 + 1 file changed, 1 insertion(+) (limited to 'video/out/vulkan/common.h') diff --git a/video/out/vulkan/common.h b/video/out/vulkan/common.h index 4c0e783f0e..d0d14e28c2 100644 --- a/video/out/vulkan/common.h +++ b/video/out/vulkan/common.h @@ -45,6 +45,7 @@ struct mpvk_ctx { struct vk_malloc *alloc; // memory allocator for this device struct vk_cmdpool *pool; // primary command pool for this device struct vk_cmd *last_cmd; // most recently submitted command + struct spirv_compiler *spirv; // GLSL -> SPIR-V compiler // Cached capabilities VkPhysicalDeviceLimits limits; -- cgit v1.2.3
