Description

apiext:VK_KHR_maintenance8 adds a collection of minor features, none of which would warrant an entire extension of their own.

The new features are as follows:

  • Allow copies between depth/stencil and “matching” color attachments

  • Allow dstCache in vkMergePipelineCaches to be implicitly synchronized.

  • Require src/dst sync scopes to work when doing queue family ownership transfers

  • Support Offset (as an alternative to ConstOffset) image operand in texture sampling and fetch operations

  • Use the SPIR-V definition of code:OpSRem and code:OpSMod, making these operations produce well-defined results for negative operands

  • Loosen layer restrictions when blitting from 3D images to other image types

  • Add space for an additional 64 access flags for use with VkMemoryBarrier2, VkBufferMemoryBarrier2, and VkImageMemoryBarrier2

Issues

None.
