- * track of the queue, the FIFO, command parsing and so
- * on. This is the one comparable to the 300 series.
- * 2. VRAM queue mode (bit 6, 0x40). In this case, one will
- * have to do queue management himself. Register 0x85c4 will
- * hold the location of the next free queue slot, 0x85c8
- * is the "queue read pointer" whose way of working is
- * unknown to me. Anyway, this mode would require a
- * translation of the MMIO commands to some kind of
- * accelerator assembly and writing these commands
- * to the memory location pointed to by 0x85c4.
- * We will not use this, as nobody knows how this
- * "assembly" works, and as it would require a complete
- * re-write of the accelerator code.
- * 3. AGP queue mode (bit 7, 0x80). Works as 2., but keeps the
- * queue in AGP memory space.
- *
- * SR26 bit 4 is called "Bypass H/W queue".
- * SR26 bit 1 is called "Enable Command Queue Auto Correction"
- * SR26 bit 0 resets the queue
- * Size of queue memory is encoded in bits 3:2 like this:
- * 00 (0x00) 512K
- * 01 (0x04) 1M
- * 10 (0x08) 2M
- * 11 (0x0C) 4M
- * The queue location is to be written to 0x85C0.
