+ * - page registers for 0-3 use bit 0, represent 64K pages
+ *
+ * DMA transfers are limited to the lower 16MB of _physical_ memory.
+ * Note that addresses loaded into registers must be _physical_ addresses,
+ * not logical addresses (which may differ if paging is active).
+ *
+ * Address mapping for channels 0-3:
+ *
+ * A23 ... A16 A15 ... A8 A7 ... A0 (Physical addresses)
+ * | ... | | ... | | ... |
+ * | ... | | ... | | ... |
+ * | ... | | ... | | ... |
+ * P7 ... P0 A7 ... A0 A7 ... A0
+ * | Page | Addr MSB | Addr LSB | (DMA registers)
+ *
+ * Address mapping for channels 5-7:
+ *
+ * A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0 (Physical addresses)
+ * | ... | \ \ ... \ \ \ ... \ \
+ * | ... | \ \ ... \ \ \ ... \ (not used)
+ * | ... | \ \ ... \ \ \ ... \
+ * P7 ... P1 (0) A7 A6 ... A0 A7 A6 ... A0
+ * | Page | Addr MSB | Addr LSB | (DMA registers)
+ *
+ * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
+ * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
+ * the hardware level, so odd-byte transfers aren't possible).
+ *
+ * Transfer count (_not # bytes_) is limited to 64K, represented as actual
+ * count - 1 : 64K => 0xFFFF, 1 => 0x0000. Thus, count is always 1 or more,
+ * and up to 128K bytes may be transferred on channels 5-7 in one operation.

+ * Apple Peripheral System Controller (PSC)
+ *
+ * The PSC is used on the AV Macs to control IO functions not handled
+ * by the VIAs (Ethernet, DSP, SCC, Sound). This includes nine DMA
+ * channels.
+ *
+ * The first seven DMA channels appear to be "one-shot" and are actually
+ * sets of two channels; one member is active while the other is being
+ * configured, and then you flip the active member and start all over again.
+ * The one-shot channels are grouped together and are:
+ *
+ * 1. SCSI
+ * 2. Ethernet Read
+ * 3. Ethernet Write
+ * 4. Floppy Disk Controller
+ * 5. SCC Channel A Receive
+ * 6. SCC Channel B Receive
+ * 7. SCC Channel A Transmit
+ *
+ * The remaining two channels are handled somewhat differently. They appear
+ * to be closely tied and share one set of registers. They also seem to run
+ * continuously, although how you keep the buffer filled in this scenario is
+ * not understood as there seems to be only one input and one output buffer
+ * pointer.
+ *
+ * Much of this was extrapolated from what was known about the Ethernet
+ * registers and subsequently confirmed using MacsBug (ie by pinging the
+ * machine with easy-to-find patterns and looking for them in the DMA
+ * buffers, or by sending a file over the serial ports and finding the
+ * file in the buffers.)

+/* Core file format: The core file is written in such a way that gdb
+ can understand it and provide useful information to the user (under
+ linux we use the 'trad-core' bfd). There are quite a number of
+ obstacles to being able to view the contents of the floating point
+ registers, and until these are solved you will not be able to view the
+ contents of them. Actually, you can read in the core file and look at
+ the contents of the user struct to find out what the floating point
+ registers contain.
+ The actual file contents are as follows:
+ UPAGE: 1 page consisting of a user struct that tells gdb what is present
+ in the file. Directly after this is a copy of the task_struct, which
+ is currently not used by gdb, but it may come in useful at some point.
+ All of the registers are stored as part of the upage. The upage should
+ always be only one page.
+ DATA: The data area is stored. We use current->end_text to
+ current->brk to pick up all of the user variables, plus any memory
+ that may have been malloced. No attempt is made to determine if a page
+ is demand-zero or if a page is totally unused, we just cover the entire
+ range. All of the addresses are rounded in such a way that an integral
+ number of pages is written.
+ STACK: We need the stack information in order to get a meaningful
+ backtrace. We need to write the data from (esp) to
+ current->start_stack, so we round each of these off in order to be able
+ to write an integer number of pages.
+ The minimum core file size is 3 pages, or 12288 bytes.
