VKEVENTRESET

VKEVENTRESET refers to the operation of resetting a Vulkan event object to the unsignaled state. In Vulkan, VkEvent is a binary synchronization primitive used to coordinate work between host and device or between queue submissions. An event can be in either signaled or unsignaled state, and new events start unsignaled.

Resetting an event is a common step when reusing it for a new synchronization point. The reset clears any previous signaled condition so that subsequent operations that wait for the event will block until a new signal occurs. There are two ways to perform a reset, depending on where the work is executed.

Host-side reset is performed with the function vkResetEvent, which resets the specified event to the unsignaled state from the host side. Device-side resets can be performed within a command buffer using the command vkCmdResetEvent, allowing the reset to participate in a recorded sequence of GPU operations. Conversely, signaling an event is done with vkSetEvent or vkCmdSetEvent.

The state of an event can be observed or waited upon. The current state may be queried with vkGetEventStatus, and events can participate in pipeline barriers or dependency structures to synchronize execution across queues or between host and device.

Notes and best practices: use VKEVENTRESET when you need to reuse an event after it has been signaled, and ensure resets occur at appropriate points in your synchronization flow to avoid race conditions. Related primitives include VkEvent, vkCreateEvent, vkDestroyEvent, and the set/get operations vkSetEvent, vkResetEvent, vkCmdSetEvent, vkCmdResetEvent, vkGetEventStatus.
