Description
VK_KHR_maintenance7 adds a collection of minor features, none of which would warrant an entire extension of their own.
The proposed new features are as follows:
- 
Add a property query to determine if a framebuffer writes to depth or stencil aspect does not trigger a write access in the sibling aspect. For example, this allows sampling stencil aspect as a texture while rendering to the sibling depth attachment and vice-versa given appropriate image layouts. 
- 
Add a way to query information regarding the underlying devices in environments where the Vulkan implementation is provided through layered implementations. For example, running on Mesa/Venus, driver ID is returned as VK_DRIVER_ID_MESA_VENUS, but it can be necessary to know what the real driver under the hood is. The new VkPhysicalDeviceLayeredApiPropertiesKHR structure can be used to gather information regarding layers underneath the top-level physical device.
- 
Promote VK_RENDERING_CONTENTS_INLINE_BIT_EXTandVK_SUBPASS_CONTENTS_INLINE_AND_SECONDARY_COMMAND_BUFFERS_EXTto KHR
- 
Add a limit to report the maximum total count of dynamic uniform buffers and dynamic storage buffers that can be included in a pipeline layout. 
- 
Require that for an unsigned integer query, the 32-bit result value must be equal to the 32 least significant bits of the equivalent 64-bit result value. 
- 
Add query for robust access support when using fragment shading rate attachments
