Description
VK_KHR_maintenance5
adds a collection of minor features, none of which
would warrant an entire extension of their own.
The new features are as follows:
-
A new
VK_FORMAT_A1B5G5R5_UNORM_PACK16_KHR
format -
A new
VK_FORMAT_A8_UNORM_KHR
format -
A property to indicate that multisample coverage operations are performed after sample counting in EarlyFragmentTests mode
-
Relax VkBufferView creation requirements by allowing subsets of the associated VkBuffer usage using
VkBufferUsageFlags2CreateInfoKHR
-
A new command vkCmdBindIndexBuffer2KHR, allowing a range of memory to be bound as an index buffer
-
vkGetDeviceProcAddr must return
NULL
for supported core functions beyond the version requested by the application. -
A property to indicate that the sample mask test is performed after sample counting in EarlyFragmentTests mode
-
vkCmdBindVertexBuffers2
now supports usingVK_WHOLE_SIZE
in thepSizes
parameter. -
A default size of 1.0 is used if
PointSize
is not written -
Shader modules are deprecated - applications can now pass VkShaderModuleCreateInfo as a chained structure to pipeline creation via VkPipelineShaderStageCreateInfo
-
A function vkGetRenderingAreaGranularityKHR to query the optimal render area for a dynamic rendering instance.
-
A property to indicate that depth/stencil texturing operations with
VK_COMPONENT_SWIZZLE_ONE
have defined behavior -
Add vkGetImageSubresourceLayout2KHR and a new function vkGetDeviceImageSubresourceLayoutKHR to allow the application to query the image memory layout without having to create an image object and query it.
-
Allow
VK_REMAINING_ARRAY_LAYERS
as thelayerCount
member of VkImageSubresourceLayers -
Adds stronger guarantees for propagation of
VK_ERROR_DEVICE_LOST
return values -
A property to indicate whether
PointSize
controls the final rasterization of polygons if polygon mode isVK_POLYGON_MODE_POINT
-
Two properties to indicate the non-strict line rasterization algorithm used
-
Two new flags words VkPipelineCreateFlagBits2KHR and VkBufferUsageFlagBits2KHR
-
Physical-device-level functions can now be called with any value in the valid range for a type beyond the defined enumerants, such that applications can avoid checking individual features, extensions, or versions before querying supported properties of a particular enumerant.
-
Clarification that copies between images of any type are allowed, treating 1D images as 2D images with a height of 1.
