25 * NOTES about DMA transfers:
26 *
27 * controller 1: channels 0-3, byte operations, ports 00-1F
28 * controller 2: channels 4-7, word operations, ports C0-DF
29 *
30 * - ALL registers are 8 bits only, regardless of transfer size
31 * - channel 4 is not used - cascades 1 into 2.
32 * - channels 0-3 are byte - addresses/counts are for physical bytes
33 * - channels 5-7 are word - addresses/counts are for physical words
34 * - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
35 * - transfer count loaded to registers is 1 less than actual count
36 * - controller 2 offsets are all even (2x offsets for controller 1)
37 * - page registers for 5-7 don't use data bit 0, represent 128K pages
38 * - page registers for 0-3 use bit 0, represent 64K pages
39 *
40 * DMA transfers are limited to the lower 16MB of _physical_ memory.
41 * Note that addresses loaded into registers must be _physical_ addresses,
42 * not logical addresses (which may differ if paging is active).
43 *
44 * Address mapping for channels 0-3:
45 *
46 * A23 ... A16 A15 ... A8 A7 ... A0 (Physical addresses)
47 * | ... | | ... | | ... |
48 * | ... | | ... | | ... |
49 * | ... | | ... | | ... |
50 * P7 ... P0 A7 ... A0 A7 ... A0
51 * | Page | Addr MSB | Addr LSB | (DMA registers)
52 *
53 * Address mapping for channels 5-7:
54 *
55 * A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0 (Physical addresses)
56 * | ... | \ \ ... \ \ \ ... \ \
57 * | ... | \ \ ... \ \ \ ... \ (not used)
58 * | ... | \ \ ... \ \ \ ... \
59 * P7 ... P1 (0) A7 A6 ... A0 A7 A6 ... A0
60 * | Page | Addr MSB | Addr LSB | (DMA registers)
61 *
62 * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
63 * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
64 * the hardware level, so odd-byte transfers aren't possible).
65 *
66 * Transfer count (_not # bytes_) is limited to 64K, represented as actual
67 * count - 1 : 64K => 0xFFFF, 1 => 0x0000. Thus, count is always 1 or more,
68 * and up to 128K bytes may be transferred on channels 5-7 in one operation.
