9 | * Thanks to HighPoint Technologies for their assistance, and hardware. | |
10 | * Special Thanks to Jon Burchmore in SanDiego for the deep pockets, his | |
11 | * donation of an ABit BP6 mainboard, processor, and memory acellerated | |
12 | * development and support. | |

15 | * HighPoint has its own drivers (open source except for the RAID part) |
16 | * available from http://www.highpoint-tech.com/BIOS%20+%20Driver/. | |
17 | * This may be useful to anyone wanting to work on this driver, however do not | |
18 | * trust them too much since the code tends to become less and less meaningful | |
19 | * as the time passes... :-/ | |

21 | * Note that final HPT370 support was done by force extraction of GPL. |
22 | * | |
23 | * - add function for getting/setting power status of drive | |
24 | * - the HPT370's state machine can get confused. reset it before each dma | |
25 | * xfer to prevent that from happening. | |
26 | * - reset state engine whenever we get an error. | |
27 | * - check for busmaster state at end of dma. | |
28 | * - use new highpoint timings. | |
29 | * - detect bus speed using highpoint register. | |
30 | * - use pll if we don't have a clock table. added a 66MHz table that's | |
31 | * just 2x the 33MHz table. | |
32 | * - removed turnaround. NOTE: we never want to switch between pll and | |
33 | * pci clocks as the chip can glitch in those cases. the highpoint | |
34 | * approved workaround slows everything down too much to be useful. in | |
35 | * addition, we would have to serialize access to each chip. | |
36 | * Adrian Sun <a.sun@sun.com> | |
37 | * | |
38 | * add drive timings for 66MHz PCI bus, | |
39 | * fix ATA Cable signal detection, fix incorrect /proc info | |
40 | * add /proc display for per-drive PIO/DMA/UDMA mode and | |
41 | * per-channel ATA-33/66 Cable detect. | |
42 | * Duncan Laurie <void@sun.com> | |
43 | * | |
44 | * fixup /proc output for multiple controllers | |
45 | * Tim Hockin <thockin@sun.com> | |
46 | * | |
47 | * On hpt366: | |
48 | * Reset the hpt366 on error, reset on dma | |
49 | * Fix disabling Fast Interrupt hpt366. | |
50 | * Mike Waychison <crlf@sun.com> | |
51 | * | |
52 | * Added support for 372N clocking and clock switching. The 372N needs | |
53 | * different clocks on read/write. This requires overloading rw_disk and | |
54 | * other deeply crazy things. Thanks to <http://www.hoerstreich.de> for | |
55 | * keeping me sane. | |
56 | * Alan Cox <alan@redhat.com> | |

58 | * - fix the clock turnaround code: it was writing to the wrong ports when |
59 | * called for the secondary channel, caching the current clock mode per- | |
60 | * channel caused the cached register value to get out of sync with the | |
61 | * actual one, the channels weren't serialized, the turnaround shouldn't | |
62 | * be done on 66 MHz PCI bus | |
7b73ee05 SS |
63 | * - disable UltraATA/100 for HPT370 by default as the 33 MHz clock being used |
64 | * does not allow for this speed anyway | |
65 | * - avoid touching disabled channels (e.g. HPT371/N are single channel chips, | |
66 | * their primary channel is kind of virtual, it isn't tied to any pins) | |
471a0bda SS |
67 | * - fix/remove bad/unused timing tables and use one set of tables for the whole |
68 | * HPT37x chip family; save space by introducing the separate transfer mode | |
69 | * table in which the mode lookup is done | |
26c068da SS |
70 | * - use f_CNT value saved by the HighPoint BIOS as reading it directly gives |
71 | * the wrong PCI frequency since DPLL has already been calibrated by BIOS | |
33b18a60 SS |
72 | * - fix the hotswap code: it caused RESET- to glitch when tristating the bus, |
73 | * and for HPT36x the obsolete HDIO_TRISTATE_HWIF handler was called instead | |
73d1dd93 SS |
74 | * - pass to init_chipset() handlers a copy of the IDE PCI device structure as |
75 | * they tamper with its fields | |
7b73ee05 SS |
76 | * - pass to the init_setup handlers a copy of the ide_pci_device_t structure |
77 | * since they may tamper with its fields | |
90778574 SS |
78 | * - prefix the driver startup messages with the real chip name |
79 | * - claim the extra 240 bytes of I/O space for all chips | |
e139b0b0 | 80 | * - optimize the rate masking/filtering and the drive list lookup code |
b4586715 | 81 | * - use pci_get_slot() to get to the function 1 of HPT36x/374 |
7b73ee05 SS |
82 | * - cache offset of the channel's misc. control registers (MCRs) being used |
83 | * throughout the driver | |
84 | * - only touch the relevant MCR when detecting the cable type on HPT374's | |
85 | * function 1 | |
abc4ad4c | 86 | * - rename all the register related variables consistently |
7b73ee05 SS |
87 | * - move all the interrupt twiddling code from the speedproc handlers into |
88 | * init_hwif_hpt366(), also grouping all the DMA related code together there | |
89 | * - merge two HPT37x speedproc handlers, fix the PIO timing register mask and | |
90 | * separate the UltraDMA and MWDMA masks there to avoid changing PIO timings | |
91 | * when setting an UltraDMA mode | |
92 | * - fix hpt3xx_tune_drive() to set the PIO mode requested, not always select | |
93 | * the best possible one | |
4bf63de2 | 94 | * - clean up DMA timeout handling for HPT370 |
7b73ee05 SS |
95 | * - switch to using the enumeration type to differ between the numerous chip |
96 | * variants, matching PCI device/revision ID with the chip type early, at the | |
97 | * init_setup stage | |
98 | * - extend the hpt_info structure to hold the DPLL and PCI clock frequencies, | |
99 | * stop duplicating it for each channel by storing the pointer in the pci_dev | |
100 | * structure: first, at the init_setup stage, point it to a static "template" | |
101 | * with only the chip type and its specific base DPLL frequency, the highest | |
102 | * supported DMA mode, and the chip settings table pointer filled, then, at | |
103 | * the init_chipset stage, allocate per-chip instance and fill it with the | |
104 | * rest of the necessary information | |
105 | * - get rid of the constant thresholds in the HPT37x PCI clock detection code, | |
106 | * switch to calculating PCI clock frequency based on the chip's base DPLL | |
107 | * frequency | |
108 | * - switch to using the DPLL clock and enable UltraATA/133 mode by default on | |
109 | * anything newer than HPT370/A | |
110 | * - fold PCI clock detection and DPLL setup code into init_chipset_hpt366(); | |
111 | * unify HPT36x/37x timing setup code and the speedproc handlers by joining | |
112 | * the register setting lists into the table indexed by the clock selected | |
