- * arch/alpha/lib/ev6-strncpy_from_user.S
- * 21264 version contributed by Rick Gorton <rick.gorton@alpha-processor.com>
- *
- * Just like strncpy except in the return value:
- *
- * -EFAULT       if an exception occurs before the terminator is copied.
- * N             if the buffer filled.
- *
- * Otherwise the length of the string is returned.
- *
- * Much of the information about 21264 scheduling/coding comes from:
- *      Compiler Writer's Guide for the Alpha 21264
- *      abbreviated as 'CWG' in other comments here
- *      ftp.digital.com/pub/Digital/info/semiconductor/literature/dsc-library.html
- * Scheduling notation:
- *      E       - either cluster
- *      U       - upper subcluster; U0 - subcluster U0; U1 - subcluster U1
- *      L       - lower subcluster; L0 - subcluster L0; L1 - subcluster L1
- * A bunch of instructions got moved and temp registers were changed
- * to aid in scheduling.  Control flow was also re-arranged to eliminate
- * branches, and to provide longer code sequences to enable better scheduling.
- * A total rewrite (using byte load/stores for start & tail sequences)
- * is desirable, but very difficult to do without a from-scratch rewrite.
- * Save that for the future.

- * Return the length of the string including the NULL terminator

- *
- * In places where it is critical to limit the processing time,

- * boundary when doing so.
- *
- * Much of the information about 21264 scheduling/coding comes from:
- *      Compiler Writer's Guide for the Alpha 21264
- *      abbreviated as 'CWG' in other comments here
- *      ftp.digital.com/pub/Digital/info/semiconductor/literature/dsc-library.html
- * Scheduling notation:
- *      E       - either cluster
- *      U       - upper subcluster; U0 - subcluster U0; U1 - subcluster U1
- *      L       - lower subcluster; L0 - subcluster L0; L1 - subcluster L1
- * Try not to change the actual algorithm if possible for consistency.

- * NOTES about DMA transfers:
- *
- *  controller 1: channels 0-3, byte operations, ports 00-1F
- *  controller 2: channels 4-7, word operations, ports C0-DF
- *
- *  - ALL registers are 8 bits only, regardless of transfer size
- *  - channel 4 is not used - cascades 1 into 2.
- *  - channels 0-3 are byte - addresses/counts are for physical bytes
- *  - channels 5-7 are word - addresses/counts are for physical words
- *  - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
- *  - transfer count loaded to registers is 1 less than actual count
- *  - controller 2 offsets are all even (2x offsets for controller 1)
- *  - page registers for 5-7 don't use data bit 0, represent 128K pages
- *  - 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.
