2 * arch/alpha/lib/ev6-strncpy_from_user.S
3 * 21264 version contributed by Rick Gorton <rick.gorton@alpha-processor.com>
4 *
5 * Just like strncpy except in the return value:
6 *
7 * -EFAULT if an exception occurs before the terminator is copied.
8 * N if the buffer filled.
9 *
10 * Otherwise the length of the string is returned.
11 *
12 * Much of the information about 21264 scheduling/coding comes from:
13 * Compiler Writer's Guide for the Alpha 21264
14 * abbreviated as 'CWG' in other comments here
15 * ftp.digital.com/pub/Digital/info/semiconductor/literature/dsc-library.html
16 * Scheduling notation:
17 * E - either cluster
18 * U - upper subcluster; U0 - subcluster U0; U1 - subcluster U1
19 * L - lower subcluster; L0 - subcluster L0; L1 - subcluster L1
20 * A bunch of instructions got moved and temp registers were changed
21 * to aid in scheduling. Control flow was also re-arranged to eliminate
22 * branches, and to provide longer code sequences to enable better scheduling.
23 * A total rewrite (using byte load/stores for start & tail sequences)
24 * is desirable, but very difficult to do without a from-scratch rewrite.
25 * Save that for the future.

23 * controller 2: channels 4-7, word operations, ports C0-DF
24 *
25 * - ALL registers are 8 bits only, regardless of transfer size
26 * - channel 4 is not used - cascades 1 into 2.
27 * - channels 0-3 are byte - addresses/counts are for physical bytes
28 * - channels 5-7 are word - addresses/counts are for physical words
29 * - transfers must not cross physical 64K (0-3) or 128K (5-7) boundaries
30 * - transfer count loaded to registers is 1 less than actual count
31 * - controller 2 offsets are all even (2x offsets for controller 1)
32 * - page registers for 5-7 don't use data bit 0, represent 128K pages
33 * - page registers for 0-3 use bit 0, represent 64K pages
34 *
35 * DMA transfers are limited to the lower 16MB of _physical_ memory.
36 * Note that addresses loaded into registers must be _physical_ addresses,
37 * not logical addresses (which may differ if paging is active).
38 *
39 * Address mapping for channels 0-3:
40 *
41 * A23 ... A16 A15 ... A8 A7 ... A0 (Physical addresses)
42 * | ... | | ... | | ... |
43 * | ... | | ... | | ... |
44 * | ... | | ... | | ... |
45 * P7 ... P0 A7 ... A0 A7 ... A0
46 * | Page | Addr MSB | Addr LSB | (DMA registers)
47 *
48 * Address mapping for channels 5-7:
49 *
50 * A23 ... A17 A16 A15 ... A9 A8 A7 ... A1 A0 (Physical addresses)
51 * | ... | \ \ ... \ \ \ ... \ \
52 * | ... | \ \ ... \ \ \ ... \ (not used)
53 * | ... | \ \ ... \ \ \ ... \
54 * P7 ... P1 (0) A7 A6 ... A0 A7 A6 ... A0
55 * | Page | Addr MSB | Addr LSB | (DMA registers)
56 *
57 * Again, channels 5-7 transfer _physical_ words (16 bits), so addresses
58 * and counts _must_ be word-aligned (the lowest address bit is _ignored_ at
59 * the hardware level, so odd-byte transfers aren't possible).
60 *
61 * Transfer count (_not # bytes_) is limited to 64K, represented as actual
62 * count - 1 : 64K => 0xFFFF, 1 => 0x0000. Thus, count is always 1 or more,
63 * and up to 128K bytes may be transferred on channels 5-7 in one operation.

5 This enables PWM support through the generic PWM framework. 5 Generic Pulse-Width Modulation (PWM) support.
6 You only need to enable this, if you also want to enable 6
7 one or more of the PWM drivers below. 7 In Pulse-Width Modulation, a variation of the width of pulses
8 8 in a rectangular pulse signal is used as a means to alter the
9 If unsure, say N. 9 average power of the signal. Applications include efficient
10 power delivery and voltage regulation. In computer systems,
11 PWMs are commonly used to control fans or the brightness of
12 display backlights.
13
14 This framework provides a generic interface to PWM devices
15 within the Linux kernel. On the driver side it provides an API
16 to register and unregister a PWM chip, an abstraction of a PWM
17 controller, that supports one or more PWM devices. Client
18 drivers can request PWM devices and use the generic framework
19 to configure as well as enable and disable them.
20
21 This generic framework replaces the legacy PWM framework which
22 allows only a single driver implementing the required API. Not
23 all legacy implementations have been ported to the framework
24 yet. The framework provides an API that is backward compatible
25 with the legacy framework so that existing client drivers
26 continue to work as expected.

28 If unsure, say no.
