like, that's the whole vibe. one arg, one int back. no cap. π
π ARGUMENTS π
rdevβ aradeon_devicepointer. it's giving "the whole GPU situation in one struct" energy, and she's the main character here fr fr. π«Ά
π₯ DESCRIPTION π₯
so what she actually does: she sets up the gfx DMA ring buffers and enables them (this is the CIK flavor, iykyk). π
returns 0 for success, and an error for failure. that's it, that's the deal. simple, iconic, no notes. π
ngl bestie, don't sleep on the return value β 0 means slay, anything else means the vibes are off and something failed. π
