C Specification
Performance counters have an associated scope. This scope describes the granularity of a performance counter.
The performance counter scope types which may be returned in
VkPerformanceCounterKHR::scope are:
// Provided by VK_KHR_performance_query
typedef enum VkPerformanceCounterScopeKHR {
VK_PERFORMANCE_COUNTER_SCOPE_COMMAND_BUFFER_KHR = 0,
VK_PERFORMANCE_COUNTER_SCOPE_RENDER_PASS_KHR = 1,
VK_PERFORMANCE_COUNTER_SCOPE_COMMAND_KHR = 2,
// VK_QUERY_SCOPE_COMMAND_BUFFER_KHR is a legacy alias
VK_QUERY_SCOPE_COMMAND_BUFFER_KHR = VK_PERFORMANCE_COUNTER_SCOPE_COMMAND_BUFFER_KHR,
// VK_QUERY_SCOPE_RENDER_PASS_KHR is a legacy alias
VK_QUERY_SCOPE_RENDER_PASS_KHR = VK_PERFORMANCE_COUNTER_SCOPE_RENDER_PASS_KHR,
// VK_QUERY_SCOPE_COMMAND_KHR is a legacy alias
VK_QUERY_SCOPE_COMMAND_KHR = VK_PERFORMANCE_COUNTER_SCOPE_COMMAND_KHR,
} VkPerformanceCounterScopeKHR;Description
-
VK_PERFORMANCE_COUNTER_SCOPE_COMMAND_BUFFER_KHR - the performance counter scope is a single complete command buffer.
-
VK_PERFORMANCE_COUNTER_SCOPE_RENDER_PASS_KHR - the performance counter scope is zero or more complete render passes. The performance query containing the performance counter must begin and end outside a render pass instance.
-
VK_PERFORMANCE_COUNTER_SCOPE_COMMAND_KHR - the performance counter scope is zero or more commands.
