299 objects in GPU memory, and on state change only emit pointer
300 (via CP_SET_DRAW_STATE), which should be nice for reducing CPU

395 the firmware code that handles the packet writes.

397 Note that for CL, starting with a6xx, the preferred # of local
398 threads is no longer the same as the max, implying that the shader

447 Is 0x8801 a register offset?
448 This appears to be a special sort of register write packet
449 more or less, but the firmware has some special handling..
450 Seems like it intercepts/modifies certain register offsets,
451 but others are treated like a normal PKT4 reg write. I
452 guess there are some registers that the fw controls certain
