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

58 59 60 61 62 |
* - fix the clock turnaround code: it was writing to the wrong ports when * called for the secondary channel, caching the current clock mode per- * channel caused the cached register value to get out of sync with the * actual one, the channels weren't serialized, the turnaround shouldn't * be done on 66 MHz PCI bus |
7b73ee05d hpt366: init code... |
63 64 65 66 |
* - disable UltraATA/100 for HPT370 by default as the 33 MHz clock being used * does not allow for this speed anyway * - avoid touching disabled channels (e.g. HPT371/N are single channel chips, * their primary channel is kind of virtual, it isn't tied to any pins) |
