+ * the device will place data on the correct byte(s) of the data bus, as the

+ * devices will find single mode transfers useful. Dual address DMA mode

+ * is useful for 8 and 16 bit devices. This is the mode that is supported

+ * The big difference, however, is the lack of device-requested DMA.  All modes

+ * address' set up by set_dma_device_addr.
+ *
+ * Therefore, there are two options.  One is to use set_dma_addr and set_dma_device_addr,
+ * which will act exactly as above in -- it will look to see if the source is set to
+ * autoincrement, and if so it will make the source use the set_dma_addr value and the
+ * destination the set_dma_device_addr value.  Otherwise the source will be set to the
+ * set_dma_device_addr value and the destination will get the set_dma_addr value.
+ *
+ * The other is to use the provided set_dma_src_addr and set_dma_dest_addr functions
+ * and make it explicit.  Depending on what you're doing, one of these two should work

+ * 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.)

+ * 16 bit reads and writes are necessary for the NetUSBee adapter's USB
+ * chipset - 16 bit words are read straight off the ROM port while 16 bit
+ * reads are split into two byte writes. The low byte is latched to the
+ * NetUSBee buffer by a read from the _read_ window (with the data pattern
+ * asserted as A1-A8 address pattern). The high byte is then written to the
+ * write range as usual, completing the write cycle.

+/* 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.
