Description

VK_KHR_maintenance10 adds a collection of minor features, none of which would warrant an entire extension of their own.

The new features are as follows:

• New image format feature bits that indicate support for copying depth or stencil aspects using non-graphics queue families
• If vkCmdSetSampleMaskEXT is called with pSampleMask set to NULL, it is treated as if the mask has all bits set to 1.
• Add vkCmdEndRendering2KHR as an extensible version of vkCmdEndRendering
• Add input attachment information to dynamic rendering
• Require that vertex inputs follow sRGB encoding when those formats are used, instead of being underspecified.
• Add a query to determine if sRGB images are resolved in nonlinear or linear space by default
• Add an optional feature to allow applications to override the default sRGB resolve behavior
• Add resolve mode and depth-stencil resolve support to vkCmdResolveImage2 to bring it in-line with render pass attachment resolves
