- * 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.

- * 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.

/*

- * As the default for CAN FD should be to support the high data rate in the
- * payload section of the frame (HDR) and to support up to 64 byte in the
- * data section (EDL) the bits are only set in the non-default case.
- * Btw. as long as there's no real implementation for CAN FD network driver
- * these bits are only preliminary.
+ * The use of struct canfd_frame implies the Extended Data Length (EDL) bit to
+ * be set in the CAN frame bitstream on the wire. The EDL bit switch turns
+ * the CAN controllers bitstream processor into the CAN FD mode which creates
+ * two new options within the CAN FD frame specification:
*
- * RX: NOHDR/NOEDL - info about received CAN FD frame
- * ESI - bit from originating CAN controller
- * TX: NOHDR/NOEDL - control per-frame settings if supported by CAN controller
- * ESI - bit is set by local CAN controller
+ * Bit Rate Switch - to indicate a second bitrate is/was used for the payload
+ * Error State Indicator - represents the error state of the transmitting node
+ *
+ * As the CANFD_ESI bit is internally generated by the transmitting CAN
+ * controller only the CANFD_BRS bit is relevant for real CAN controllers when
+ * building a CAN FD frame for transmission. Setting the CANFD_ESI bit can make
+ * sense for virtual CAN interfaces to test applications with echoed frames.
