VkGpaDeviceClockModeAMD

Values which can be set in VkGpaDeviceClockModeAMD are:

typedef enum VkGpaDeviceClockModeAMD {
    VK_GPA_DEVICE_CLOCK_MODE_DEFAULT_AMD = 0,
    VK_GPA_DEVICE_CLOCK_MODE_QUERY_AMD = 1,
    VK_GPA_DEVICE_CLOCK_MODE_PROFILING_AMD = 2,
    VK_GPA_DEVICE_CLOCK_MODE_MIN_MEMORY_AMD = 3,
    VK_GPA_DEVICE_CLOCK_MODE_MIN_ENGINE_AMD = 4,
    VK_GPA_DEVICE_CLOCK_MODE_PEAK_AMD = 5,
} VkGpaDeviceClockModeAMD;

pub struct GpaDeviceClockModeAMD(u32);
impl GpaDeviceClockModeAMD {
    pub const DEFAULT: Self = 0;
    pub const QUERY: Self = 1;
    pub const PROFILING: Self = 2;
    pub const MIN_MEMORY: Self = 3;
    pub const MIN_ENGINE: Self = 4;
    pub const PEAK: Self = 5;
}

• VK_GPA_DEVICE_CLOCK_MODE_DEFAULT_AMD specifies that device clocks and other power settings are restored to their default values.
• VK_GPA_DEVICE_CLOCK_MODE_QUERY_AMD specifies that the current clock values should be queried, with no new values set.
• VK_GPA_DEVICE_CLOCK_MODE_PROFILING_AMD specifies that clocks are set to a constant amount which is known to be power and thermal sustainable. The engine/memory clock ratio will be kept the same as much as possible.
• VK_GPA_DEVICE_CLOCK_MODE_MIN_MEMORY_AMD specifies that the memory clock is set to the lowest available level and the engine clock is set to a thermal and power sustainable level.
• VK_GPA_DEVICE_CLOCK_MODE_MIN_ENGINE_AMD specifies that the engine clock is set to the lowest available level and the memory clock is set to a thermal and power sustainable level.
• VK_GPA_DEVICE_CLOCK_MODE_PEAK_AMD specifies that the clocks set to maximum when possible and fans set to maximum. Under power and thermal constraints device will clock down.
