VkPerfHintTypeQCOM(3)

C Specification

Possible values of VkPerfHintInfoQCOM::type, specifying the type of performance hint to apply, are:

// Provided by VK_QCOM_queue_perf_hint
typedef enum VkPerfHintTypeQCOM {
    VK_PERF_HINT_TYPE_DEFAULT_QCOM = 0,
    VK_PERF_HINT_TYPE_FREQUENCY_MIN_QCOM = 1,
    VK_PERF_HINT_TYPE_FREQUENCY_MAX_QCOM = 2,
    VK_PERF_HINT_TYPE_FREQUENCY_SCALED_QCOM = 3,
} VkPerfHintTypeQCOM;

Description

VK_PERF_HINT_TYPE_DEFAULT_QCOM resets the performance hint state back to default for the queue.
VK_PERF_HINT_TYPE_FREQUENCY_MIN_QCOM specifies the queue should prioritize power and sets the frequency constraints f_min and f_max to F_min.
VK_PERF_HINT_TYPE_FREQUENCY_MAX_QCOM specifies the queue should prioritize performance and sets the frequency constraints f_min and f_max to F_max.
VK_PERF_HINT_TYPE_FREQUENCY_SCALED_QCOM specifies the queue should be balanced between performance and power and sets the frequency constraint f_min by applying a scale factor to F_max. No constraint is applied to f_max.
