23/*******************************************************************************
24 ***** INTRODUCTION ***********
25 * On the Blackfin, the interrupt structure allows remmapping of the hardware
26 * levels.
27 * - I'm going to assume that the H/W level is going to stay at the default
28 * settings. If someone wants to go through and abstart this out, feel free
29 * to mod the interrupt numbering scheme.
30 * - I'm abstracting the interrupts so that uClinux does not know anything
31 * about the H/W levels. If you want to change the H/W AND keep the abstracted
32 * levels that uClinux sees, you should be able to do most of it here.
33 * - I've left the "abstract" numbering sparce in case someone wants to pull the
34 * interrupts apart (just the TX/RX for the various devices)
35 *******************************************************************************/

39/*
40 * Machine specific interrupt sources.
41 *
42 * Adding an interrupt service routine for a source with this bit
43 * set indicates a special machine specific interrupt source.
44 * The machine specific files define these sources.
45 *
46 * The IRQ_MACHSPEC bit is now gone - the only thing it did was to
47 * introduce unnecessary overhead.
48 *
49 * All interrupt handling is actually machine specific so it is better
50 * to use function pointers, as used by the Sparc port, and select the
51 * interrupt handling functions when initializing the kernel. This way
52 * we save some unnecessary overhead at run-time.

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