Description

This extension allows applications to insert markers in the command stream and associate them with custom data.

If a device lost error occurs, the application may then query the implementation for the last markers to cross specific implementation-defined pipeline stages, in order to narrow down which commands were executing at the time and might have caused the failure.

Documentation

cmdSetCheckpointNV Source #

Arguments

:: forall io. MonadIO io
=> CommandBuffer	`commandBuffer` is the command buffer that will receive the marker
-> ("checkpointMarker" ::: Ptr ())	`pCheckpointMarker` is an opaque application-provided value that will be associated with the checkpoint.
-> io ()

vkCmdSetCheckpointNV - Insert diagnostic checkpoint in command stream

Valid Usage (Implicit)

commandBuffer must be a valid CommandBuffer handle

commandBuffer must be in the recording state
The CommandPool that commandBuffer was allocated from must support graphics, compute, or transfer operations
This command must only be called outside of a video coding scope

Host Synchronization

Host access to commandBuffer must be externally synchronized

Host access to the CommandPool that commandBuffer was allocated from must be externally synchronized

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 CheckpointDataNV structures

Description

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

data CheckpointDataNV Source #

VkCheckpointDataNV - Return structure for command buffer checkpoint data

Description

The stages at which a checkpoint marker can be executed are implementation-defined and can be queried by calling getPhysicalDeviceQueueFamilyProperties2.

Valid Usage (Implicit)

CheckpointDataNV
Fields stage :: PipelineStageFlagBits `stage` is a `PipelineStageFlagBits` value specifying which pipeline stage the checkpoint marker data refers to. checkpointMarker :: Ptr () `pCheckpointMarker` contains the value of the last checkpoint marker executed in the stage that `stage` refers to.
