8 * Thanks to HighPoint Technologies for their assistance, and hardware.
9 * Special Thanks to Jon Burchmore in SanDiego for the deep pockets, his
10 * donation of an ABit BP6 mainboard, processor, and memory acellerated
11 * development and support.
14 * HighPoint has its own drivers (open source except for the RAID part)
15 * available from http://www.highpoint-tech.com/BIOS%20+%20Driver/.
16 * This may be useful to anyone wanting to work on this driver, however do not
17 * trust them too much since the code tends to become less and less meaningful
18 * as the time passes... :-/
20 * Note that final HPT370 support was done by force extraction of GPL.
22 * - add function for getting/setting power status of drive
23 * - the HPT370's state machine can get confused. reset it before each dma
24 * xfer to prevent that from happening.
25 * - reset state engine whenever we get an error.
26 * - check for busmaster state at end of dma.
27 * - use new highpoint timings.
28 * - detect bus speed using highpoint register.
29 * - use pll if we don't have a clock table. added a 66MHz table that's
30 * just 2x the 33MHz table.
31 * - removed turnaround. NOTE: we never want to switch between pll and
32 * pci clocks as the chip can glitch in those cases. the highpoint
33 * approved workaround slows everything down too much to be useful. in
34 * addition, we would have to serialize access to each chip.
35 * Adrian Sun <a.sun@sun.com>
37 * add drive timings for 66MHz PCI bus,
38 * fix ATA Cable signal detection, fix incorrect /proc info
39 * add /proc display for per-drive PIO/DMA/UDMA mode and
40 * per-channel ATA-33/66 Cable detect.
41 * Duncan Laurie <void@sun.com>
43 * fixup /proc output for multiple controllers
44 * Tim Hockin <thockin@sun.com>
47 * Reset the hpt366 on error, reset on dma
48 * Fix disabling Fast Interrupt hpt366.
49 * Mike Waychison <crlf@sun.com>
51 * Added support for 372N clocking and clock switching. The 372N needs
52 * different clocks on read/write. This requires overloading rw_disk and
53 * other deeply crazy things. Thanks to <http://www.hoerstreich.de> for
55 * Alan Cox <alan@redhat.com>
57 * - fix the clock turnaround code: it was writing to the wrong ports when
58 * called for the secondary channel, caching the current clock mode per-
59 * channel caused the cached register value to get out of sync with the
60 * actual one, the channels weren't serialized, the turnaround shouldn't
61 * be done on 66 MHz PCI bus
62 * - disable UltraATA/100 for HPT370 by default as the 33 MHz clock being used
63 * does not allow for this speed anyway
64 * - avoid touching disabled channels (e.g. HPT371/N are single channel chips,
65 * their primary channel is kind of virtual, it isn't tied to any pins)
66 * - fix/remove bad/unused timing tables and use one set of tables for the whole
67 * HPT37x chip family; save space by introducing the separate transfer mode
68 * table in which the mode lookup is done
69 * - use f_CNT value saved by the HighPoint BIOS as reading it directly gives
70 * the wrong PCI frequency since DPLL has already been calibrated by BIOS;
71 * read it only from the function 0 of HPT374 chips
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
74 * - pass to init_chipset() handlers a copy of the IDE PCI device structure as
75 * they tamper with its fields
76 * - pass to the init_setup handlers a copy of the ide_pci_device_t structure
77 * since they may tamper with its fields
78 * - prefix the driver startup messages with the real chip name
79 * - claim the extra 240 bytes of I/O space for all chips
80 * - optimize the UltraDMA filtering and the drive list lookup code
81 * - use pci_get_slot() to get to the function 1 of HPT36x/374
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
86 * - rename all the register related variables consistently
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 HPT36x/HPT37x speedproc handlers, fix 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
94 * - clean up DMA timeout handling for HPT370
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
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 * UltraDMA mode, and the chip settings table pointer filled, then, at the
103 * init_chipset stage, allocate per-chip instance and fill it with the rest
104 * 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
108 * - switch to using the DPLL clock and enable UltraATA/133 mode by default on
109 * anything newer than HPT370/A (except HPT374 that is not capable of this
110 * mode according to the manual)
111 * - fold PCI clock detection and DPLL setup code into init_chipset_hpt366(),
112 * also fixing the interchanged 25/40 MHz PCI clock cases for HPT36x chips;
113 * unify HPT36x/37x timing setup code and the speedproc handlers by joining
114 * the register setting lists into the table indexed by the clock selected
115 * - set the correct hwif->ultra_mask for each individual chip
116 * - add Ultra and MW DMA mode filtering for the HPT37[24] based SATA cards
