Function Documentation

gpu_usage_cleanup()

void gpu_usage_cleanup

(

GPUUsageMonitor *

mon

)

Closes all open fdinfo streams.

gpu_usage_get_load()

float gpu_usage_get_load

(

const GPUUsageMonitor *

mon

)

Returns the last computed GPU load (0.0–100.0).

gpu_usage_init()

void gpu_usage_init

(

GPUUsageMonitor *

mon

)

Scans /proc/self/fdinfo/ and opens streams for GPU engine time reading.

gpu_usage_is_available()

bool gpu_usage_is_available

(

const GPUUsageMonitor *

mon

)

Returns true if a supported DRM driver was detected.

gpu_usage_update()

void gpu_usage_update

(

GPUUsageMonitor *

mon

)

Re-reads fdinfo streams and computes GPU load %. Should be called periodically (e.g., every 500ms).
