|
|
* 1. MMIO queue mode (bit 5, 0x20). The hardware will keep

|
* 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
