Description

This extension expands support for using VK_IMAGE_TILING_LINEAR images as color attachments when all the color attachments in the render pass instance have VK_IMAGE_TILING_LINEAR tiling. This extension adds a new flag bit VK_FORMAT_FEATURE_2_LINEAR_COLOR_ATTACHMENT_BIT_NV that extends the existing VkFormatFeatureFlagBits2KHR bits. This flag can be set for renderable color formats in the VkFormatProperties3KHR::linearTilingFeatures format properties structure member. Formats with the VK_FORMAT_FEATURE_2_LINEAR_COLOR_ATTACHMENT_BIT_NV flag may be used as color attachments as long as all the color attachments in the render pass instance have VK_IMAGE_TILING_LINEAR tiling, and the formats their images views are created with have VkFormatProperties3KHR::linearTilingFeatures which include VK_FORMAT_FEATURE_2_LINEAR_COLOR_ATTACHMENT_BIT_NV. This extension supports both dynamic rendering and traditional render passes.
