🌸 NAME 🌸

kfd_get_cu_occupancy — collect the number of waves in-flight on this device by the current process, then translate that acquired wave count into the number of compute units that are occupied 💖

🦋 SYNOPSIS 🦋

int kfd_get_cu_occupancy (struct attribute *attr , char *buffer );

🎀 ARGUMENTS 🎀

• attr — handle of the attribute that allows reporting of wave count. bestie, this attribute handle encapsulates the GPU device it is associated with, which is what lets it collect waves in flight and all that good stuff 👑
• buffer — handle of the user-provided buffer that gets updated with the wave count 🌈

⭐ RETURN ⭐

number of bytes written to the user buffer, or an error value 😭 periodt.
