* Update release number to 78.
Public Issues:
* Change markup so parameter descriptions include links to structures,
instead of just their names (public issue 697).
* Resume publishing updated Vulkan 1.0 + KHR extensions and Vulkan 1.0 +
all extensions versions of the specification (public issue 722).
* Reapply fixes from public pull request 698 for
`VK_ANDROID_external_memory_android_hardware_buffer`, which accidentally
were reverted at some point (public pull request 724).
* Fix undefined format valid usage statements for slink:VkImageCreateInfo
in the presence of the
`VK_ANDROID_external_memory_android_hardware_buffer` extension (public
pull request 725).
* Miscellaneous markup consistency fixes (public pull request 728).
Internal Issues:
* When building specifications containing vendor extensions, add terms to
the Khronos spec copyright specifying that the result is not a ratified
specification (internal issue 739).
* Change the value of the
pname:maxDescriptorSetUpdateAfterBindUniformBuffers minimum limit to 72
(6 times pname:maxPerStageDescriptorUpdateAfterBindUniformBuffers) in
the <<features-limits-required, Required Limits>> table (internal issue
1300).
Other Issues:
* Fix link to resource image view compatibility table in the valid usage
statements for slink:VkImageFormatListCreateInfoKHR (internal pull
request 2711).

To enable surface counters when creating a swapchain, add
|
|
sname:VkSwapchainCounterCreateInfoEXT to the pname:pNext chain of
|
|
slink:VkSwapchainCreateInfoKHR.
|
|
sname:VkSwapchainCounterCreateInfoEXT is defined as:
|
|
|
|
include::../../api/structs/VkSwapchainCounterCreateInfoEXT.txt[]
|
|
|
|
* pname:sType is the type of this structure.
|
|
* pname:pNext is `NULL` or a pointer to an extension-specific structure.
|
|
* pname:surfaceCounters is a bitmask of elink:VkSurfaceCounterFlagBitsEXT
|
|
specifying surface counters to enable for the swapchain.
|
|
|
|
.Valid Usage
|
|
****
|
|
* [[VUID-VkSwapchainCounterCreateInfoEXT-surfaceCounters-01244]]
|
|
The bits in pname:surfaceCounters must: be supported by
|
|
slink:VkSwapchainCreateInfoKHR::pname:surface, as reported by
|
|
flink:vkGetPhysicalDeviceSurfaceCapabilities2EXT.

|
|
|
|
The requested counters become active when the first presentation command for
|
|
the associated swapchain is processed by the presentation engine.
|
|
To query the value of an active counter, use:
|
|
|
|
include::../../api/protos/vkGetSwapchainCounterEXT.txt[]
|
|
|
|
* pname:device is the slink:VkDevice associated with pname:swapchain.
|
|
* pname:swapchain is the swapchain from which to query the counter value.
|
|
* pname:counter is the counter to query.
|
|
* pname:pCounterValue will return the current value of the counter.
|
|
|
|
If a counter is not available because the swapchain is out of date, the
|
|
implementation may: return ename:VK_ERROR_OUT_OF_DATE_KHR.
|
|
|
|
.Valid Usage
|
|
****
|
|
* [[VUID-vkGetSwapchainCounterEXT-swapchain-01245]]
|
|
One or more present commands on pname:swapchain must: have been
|
|
processed by the presentation engine.
