πŸ’… amdgpu_debugfs_regs_pcie64_write β€” from the Kernel API Manual, bestie

Okay so bestie, this is the manual page for amdgpu_debug...pcie64_write(9) (the header line, we're folding it in right here so you get the whole vibe πŸ’–).

__user *buf , size_t size , loff_t *pos );

Look at her. A ssize_t return, four args, immaculate energy. She ate and left no crumbs ✨
