From 3ef598c9f87145b3acca6d4ca212be021c541219 Mon Sep 17 00:00:00 2001 From: Riteo Date: Fri, 21 Oct 2022 22:40:14 +0200 Subject: Check for a Vulkan extension before checking its features For some reason AFAICT mesa reports a feature as enabled even when its extension isn't supported. The Vulkan specification says nothing aboutd this so this is technically more of a workaround, but it works. --- drivers/vulkan/vulkan_context.cpp | 46 +++++++++++++++++++++++++++++---------- 1 file changed, 34 insertions(+), 12 deletions(-) diff --git a/drivers/vulkan/vulkan_context.cpp b/drivers/vulkan/vulkan_context.cpp index f51fd2a6cf..7a5b768dca 100644 --- a/drivers/vulkan/vulkan_context.cpp +++ b/drivers/vulkan/vulkan_context.cpp @@ -687,21 +687,43 @@ Error VulkanContext::_check_capabilities() { vkGetPhysicalDeviceFeatures2_func(gpu, &device_features); - vrs_capabilities.pipeline_vrs_supported = vrs_features.pipelineFragmentShadingRate; - vrs_capabilities.primitive_vrs_supported = vrs_features.primitiveFragmentShadingRate; - vrs_capabilities.attachment_vrs_supported = vrs_features.attachmentFragmentShadingRate; + // We must check that the relative extension is present before assuming a + // feature as enabled.
