Sergei Shtylyov | 836c006 | 2006-12-13 00:35:47 -0800 | [diff] [blame] | 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... :-/ |

Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 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. |

Sergei Shtylyov | 836c006 | 2006-12-13 00:35:47 -0800 | [diff] [blame] | 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 |
Sergei Shtylyov | 7b73ee0 | 2007-02-07 18:18:16 +0100 | [diff] [blame] | 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) |
Sergei Shtylyov | 471a0bd | 2006-12-13 00:35:49 -0800 | [diff] [blame] | 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 |
Sergei Shtylyov | 26c068d | 2006-12-13 00:35:52 -0800 | [diff] [blame] | 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 |
Sergei Shtylyov | 33b18a6 | 2006-12-13 00:35:50 -0800 | [diff] [blame] | 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 |
Sergei Shtylyov | 73d1dd9 | 2006-12-13 00:35:51 -0800 | [diff] [blame] | 74 | * - pass to init_chipset() handlers a copy of the IDE PCI device structure as |
| 75 | * they tamper with its fields |
Sergei Shtylyov | 7b73ee0 | 2007-02-07 18:18:16 +0100 | [diff] [blame] | 76 | * - pass to the init_setup handlers a copy of the ide_pci_device_t structure |
| 77 | * since they may tamper with its fields |
Sergei Shtylyov | 9077857 | 2007-02-07 18:17:51 +0100 | [diff] [blame] | 78 | * - prefix the driver startup messages with the real chip name |
| 79 | * - claim the extra 240 bytes of I/O space for all chips |
Sergei Shtylyov | 2648e5d | 2007-07-09 23:17:55 +0200 | [diff] [blame] | 80 | * - optimize the UltraDMA filtering and the drive list lookup code |
Sergei Shtylyov | b458671 | 2007-02-07 18:17:54 +0100 | [diff] [blame] | 81 | * - use pci_get_slot() to get to the function 1 of HPT36x/374 |
Sergei Shtylyov | 7b73ee0 | 2007-02-07 18:18:16 +0100 | [diff] [blame] | 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 |
Sergei Shtylyov | abc4ad4 | 2007-02-07 18:18:05 +0100 | [diff] [blame] | 86 | * - rename all the register related variables consistently |
Sergei Shtylyov | 7b73ee0 | 2007-02-07 18:18:16 +0100 | [diff] [blame] | 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 |
Sergei Shtylyov | 4bf63de | 2007-02-07 18:18:13 +0100 | [diff] [blame] | 94 | * - clean up DMA timeout handling for HPT370 |
Sergei Shtylyov | 7b73ee0 | 2007-02-07 18:18:16 +0100 | [diff] [blame] | 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 |
Sergei Shtylyov | 2648e5d | 2007-07-09 23:17:55 +0200 | [diff] [blame] | 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 |
Sergei Shtylyov | 7b73ee0 | 2007-02-07 18:18:16 +0100 | [diff] [blame] | 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 |
Sergei Shtylyov | 278978e | 2007-06-08 15:14:32 +0200 | [diff] [blame] | 109 | * anything newer than HPT370/A (except HPT374 that is not capable of this |
| 110 | * mode according to the manual) |
Sergei Shtylyov | 6273d26 | 2007-02-07 18:18:20 +0100 | [diff] [blame] | 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; |
Sergei Shtylyov | 7b73ee0 | 2007-02-07 18:18:16 +0100 | [diff] [blame] | 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 |
Sergei Shtylyov | 2648e5d | 2007-07-09 23:17:55 +0200 | [diff] [blame] | 115 | * - set the correct hwif->ultra_mask for each individual chip |
