Description

This extension modifies the original core synchronization APIs to simplify the interface and improve usability of these APIs. It also adds new pipeline stage and access flag types that extend into the 64-bit range, as we have run out within the 32-bit range. The new flags are identical to the old values within the 32-bit range, with new stages and bits beyond that.

Pipeline stages and access flags are now specified together in memory barrier structures, making the connection between the two more obvious. Additionally, scoping the pipeline stages into the barrier structs allows the use of the MEMORY_READ and MEMORY_WRITE flags without sacrificing precision. The per-stage access flags should be used to disambiguate specific accesses in a given stage or set of stages - for instance, between uniform reads and sampling operations.

Layout transitions have been simplified as well; rather than requiring a different set of layouts for depth/stencil/color attachments, there are generic IMAGE_LAYOUT_ATTACHMENT_OPTIMAL_KHR and IMAGE_LAYOUT_READ_ONLY_OPTIMAL_KHR layouts which are contextually applied based on the image format. For example, for a depth format image, IMAGE_LAYOUT_READ_ONLY_OPTIMAL_KHR is equivalent to IMAGE_LAYOUT_DEPTH_READ_ONLY_OPTIMAL_KHR. IMAGE_LAYOUT_READ_ONLY_OPTIMAL_KHR also functionally replaces IMAGE_LAYOUT_SHADER_READ_ONLY_OPTIMAL.

Events are now more efficient, because they include memory dependency information when you set them on the device. Previously, this information was only known when waiting on an event, so the dependencies could not be satisfied until the wait occurred. That sometimes meant stalling the pipeline when the wait occurred. The new API provides enough information for implementations to satisfy these dependencies in parallel with other tasks.

Queue submission has been changed to wrap command buffers and semaphores in extensible structures, which incorporate changes from Vulkan 1.1, VK_KHR_device_group, and VK_KHR_timeline_semaphore. This also adds a pipeline stage to the semaphore signal operation, mirroring the existing pipeline stage specification for wait operations.

Other miscellaneous changes include:

Events can now be specified as interacting only with the device, allowing more efficient access to the underlying object.
Image memory barriers that do not perform an image layout transition can be specified by setting oldLayout equal to newLayout.
- E.g. the old and new layout can both be set to IMAGE_LAYOUT_UNDEFINED, without discarding data in the image.
Queue family ownership transfer parameters are simplified in some cases.
Where two synchronization commands need to be matched up (queue transfer operations, events), the dependency information specified in each place must now match completely for consistency.
Extensions with commands or functions with a PipelineStageFlags or PipelineStageFlagBits parameter have had those APIs replaced with equivalents using PipelineStageFlags2KHR.
The new event and barrier interfaces are now more extensible for future changes.
Relevant pipeline stage masks can now be specified as empty with the new PIPELINE_STAGE_NONE_KHR and PIPELINE_STAGE_2_NONE_KHR values.
MemoryBarrier2KHR can be chained to SubpassDependency2, overriding the original 32-bit stage and access masks.

cmdWriteBufferMarker2AMD Source #

Arguments

:: forall io. MonadIO io
=> CommandBuffer	`commandBuffer` is the command buffer into which the command will be recorded.
-> PipelineStageFlags2	`stage` specifies the pipeline stage whose completion triggers the marker write.
-> ("dstBuffer" ::: Buffer)	`dstBuffer` is the buffer where the marker will be written.
-> ("dstOffset" ::: DeviceSize)	`dstOffset` is the byte offset into the buffer where the marker will be written.
-> ("marker" ::: Word32)	`marker` is the 32-bit value of the marker.
-> io ()

vkCmdWriteBufferMarker2AMD - Execute a pipelined write of a marker value into a buffer

Description

The command will write the 32-bit marker value into the buffer only after all preceding commands have finished executing up to at least the specified pipeline stage. This includes the completion of other preceding cmdWriteBufferMarker2AMD commands so long as their specified pipeline stages occur either at the same time or earlier than this command’s specified stage.

While consecutive buffer marker writes with the same stage parameter implicitly complete in submission order, memory and execution dependencies between buffer marker writes and other operations must still be explicitly ordered using synchronization commands. The access scope for buffer marker writes falls under the ACCESS_TRANSFER_WRITE_BIT, and the pipeline stages for identifying the synchronization scope must include both stage and PIPELINE_STAGE_TRANSFER_BIT.

Note

Similar to cmdWriteTimestamp2, if an implementation is unable to write a marker at any specific pipeline stage, it may instead do so at any logically later stage.

Note

Implementations may only support a limited number of pipelined marker write operations in flight at a given time. Thus an excessive number of marker write operations may degrade command execution performance.

Description

If pCheckpointData is NULL, then the number of checkpoint markers available is returned in pCheckpointDataCount. Otherwise, pCheckpointDataCount must point to a variable set by the user to the number of elements in the pCheckpointData array, and on return the variable is overwritten with the number of structures actually written to pCheckpointData.

If pCheckpointDataCount is less than the number of checkpoint markers available, at most pCheckpointDataCount structures will be written.

Valid Usage

The device that queue belongs to must be in the lost state

Valid Usage (Implicit)

queue must be a valid Queue handle

pCheckpointDataCount must be a valid pointer to a uint32_t value
If the value referenced by pCheckpointDataCount is not 0, and pCheckpointData is not NULL, pCheckpointData must be a valid pointer to an array of pCheckpointDataCount CheckpointData2NV structures

Description

Additional queue family information can be queried by setting QueueFamilyProperties2::pNext to point to a QueueFamilyCheckpointProperties2NV structure.
