      ide: mode limiting fixes for user requested speed changes · 7670df73
      Bartlomiej Zolnierkiewicz authored
      * Add an extra argument to ide_max_dma_mode() for passing requested transfer
        mode.  Use it as an upper limit when finding the best DMA for device/host.
      
      * Rename ide_max_dma_mode() to ide_find_dma_mode() and at the same time add
        ide_max_dma_mode() wrapper which passes XFER_UDMA_6 as a requested mode to
        ide_find_dma_mode().  Also add inline ide_find_dma_mode() version for
        CONFIG_BLK_DEV_IDEDMA=n case.
      
      * Pass requested transfer mode from ide_find_dma_mode() to ide_get_mode_mask()
        to avoid false warning from eighty_ninty_three().
      
      * Use ide_find_dma_mode() to limit the user requested transfer mode in
        ide_rate_filter().  Also limit the requested mode by host max PIO mode.
      
      
      Above changes make ide_rate_filter() to:
      
      * Clip desired transfer mode down if it is invalid (values 0x0F, 0x13-0x19
        and 0x25-0x39, values > 0x46 were already clipped down, same for values
        0x25-0x39 but iff UDMA was not supported by the host).
      
      * Clip desired transfer mode down if it is currently unsupported by IDE core
        (PIO6 and MWDMA3-4, the latter were already clipped down but iff UDMA was
        not supported by the host).
      
      * Clip desired transfer mode down according to the host capabilities
        (UDMA modes were already clipped down but MWDMA/SWDMA/PIO weren't,
        also ->atapi_dma flag was not respected).
      
      * Clip desired transfer mode down according to the device capabilities
        (except PIO modes for now which require mode work) - shouldn't be a
        problem since ide_set_xfer_rate() is called _after_ device has accepted
        given transfer mode.
      
      and also result in a number of host driver specific bugfixes:

      hpt366: UltraDMA filter for SATA cards (take 2) · 2808b0a9
      Sergei Shtylyov authored
      The Marvell bridge chips used on HighPoint SATA cards do not seem to support
      the UltraDMA modes 1, 2, and 3 as well as any MWDMA modes, so the driver needs
      to account for this in the udma_filter() method.  In order to achieve that, do
      the following changes:
      
      - install the method for all chips, not only HPT36x/370 and improve the code
        formatting by killing the extra tabs while at it;
      
      - add to the end of the 'switch' statement in the method cases for HPT372[AN]
        and HPT374 chips upon which the known SATA cards are based;
      
      - use hwif->ultra_mask as a default mask for the ide_dma_filter() method to
        behave correctly;
      
      - move the HPT370[A] cases below the HPT36x case for consistency.
      
      While at it, replace the explicit UltraDMA mode masks with ATA_UDMA* constants
      all over the driver...

      Sergei Shtylyov authored
      HPT374 BIOS seems to only save f_CNT register value for the function #0 before

      from the function #0 in the driver's init_chipset() method.

      PCI: Change all drivers to use pci_device->revision · 44c10138
      Auke Kok authored
      Instead of all drivers reading pci config space to get the revision
      ID, they can now use the pci_device->revision member.
      
      This exposes some issues where drivers where reading a word or a dword
      for the revision number, and adding useless error-handling around the
      read. Some drivers even just read it for no purpose of all.
      
      In devices where the revision ID is being copied over and used in what
      appears to be the equivalent of hotpath, I have left the copy code
      and the cached copy as not to influence the driver's performance.
      
      Compile tested with make all{yes,mod}config on x86_64 and i386.

      ide: add short cables support · 49521f97
      Bartlomiej Zolnierkiewicz authored
      This patch allows users to override both host and device side cable detection
      with "ideX=ata66" kernel parameter.  Thanks to this it should be now possible
      to use UDMA > 2 modes on systems (laptops mainly) which use short 40-pin cable
      instead of 80-pin one.
      
      Next patches add automatic detection of some systems using short cables.
      
      Changes:
      
      * Rename hwif->udma_four to hwif->cbl and make it u8.
      
      * Convert all existing users accordingly (use ATA_CBL_* defines while at it).  
      
      * Add ATA_CBL_PATA40_SHORT support to ide-iops.c:eighty_ninty_three().
      
      * Use ATA_CBL_PATA40_SHORT for "ideX=ata66" kernel parameter.

      Sergei Shtylyov authored
      Simplify UltraDMA mode filtering in the driver:
      
      - make use of the newly introduced 'udma_mask' field of 'ide_pci_device_t' to
        set the correct hwif->ultra_mask, modifying init_setup_hpt366() to select
        the correct mask based on the chip revision;
      
      - replace 'max_mode' field of the 'struct hpt_info' with 'max_ultra' specifying
        the maximum UltraDMA mode allowed;
      
      - rewrite hpt3xx_udma_filter() to differ the filters based on the 'chip_type'
        field, and only use it for HPT366 and HPT370[A] where it's really necessary.

      hpt366: HPT36x PCI clock detection fix · 6273d26a
      Sergei Shtylyov authored
      Fix minor coding mistake in the HPT36x PCI clock detection code noticed by
      Bartlomiej Zolnierkiewicz -- it always reported 33 MHz due to the missing
      'break' statements.  This, however, most probably never mattered -- in fact, I
      was thinking of removing the 25/40 MHz cases completely since HPT36x BIOSes
      didn't seem to set any other value than 7 into the 'cmd_high_time' field, i.e.
       supported only 33 MHz PCI.
      
      Note that in the original driver there was another bug: 25 and 40 MHz cases
      were interchanged.  Since the 'cmd_high_time' field is in units of PCI clocks,
      a lower clock count just *cannot* correspond to a higher frequency, i.  e.  it
      should be 5 for 25 MHz PCI and 9 for 40 MHz PCI, not the other way around.

      hpt366: init code rewrite · 7b73ee05
      Sergei Shtylyov authored
      Finally, rework the driver init.  code to correctly handle all the chip
      variants HighPoint has created so far.  This should cure the rest of the
      timing issues in the driver (especially, on 66 MHz PCI) caused by the
      HighPoint's habit of switching the base DPLL clock with every new revision
      of the chips...
      
        - switch to using the enumeration type to differ between the numerous chip
          variants, matching PCI device/revision ID with the chip type early, at the
          init_setup stage;
      
        - extend the hpt_info structure to hold the DPLL and PCI clock frequencies,
          stop duplicating it for each channel by storing the pointer in the pci_dev
          structure: first, at the init_setup stage, point it to a static "template"
          with only the chip type and its specific base DPLL frequency, the highest
          supported DMA mode, and the chip settings table pointer filled, then, at
          the init_chipset stage, allocate per-chip instance  and fill it with the
          rest of the necessary information;
      
        - get rid of the constant thresholds in the HPT37x PCI clock detection code,
          switch  to calculating  PCI clock frequency based on the chip's base DPLL
          frequency;
      
        - switch to using the DPLL clock and enable UltraATA/133 mode by default on
          anything newer than HPT370/A;
      
        - fold PCI clock detection and DPLL setup code into init_chipset_hpt366(),
          unify the HPT36x/37x setup code and the speedproc handlers by joining the
          register setting lists into the table indexed by the clock selected;
      
        - add enablebits for all the chips to avoid touching disabled channels
          (though the HighPoint BIOS seem to only disable the primary one on
          HPT371/N);
      
        - separate the UltraDMA and MWDMA masks there to avoid changing PIO timings
          when setting an UltraDMA mode in hpt37x_tune_chipset().
      
      This version has been tested on HPT370/302/371N.
      
      Thanks to Alan for the inspiration. Hopefully, his libata driver will also
      benefit from the work done on this "obsolete" driver...

      hpt366: clean up DMA timeout handling for HPT370 · 4bf63de2
      Sergei Shtylyov authored
      Clean up DMA timeout handling for HPT370:
      
      - hpt370_lostirq_timeout() cleared the DMA status which made __ide_dma_end()
         called afterwards return the incorrect result, and the DMA engine was reset
         both before and after stopping DMA while the HighPoint drivers only do it
         after (which seems logical) -- fix this and also rename the function;
      
      - get rid of the needless mutual recursion in hpt370_ide_dma_end() and
         hpt370_ide_dma_timeout();
      
      - get rid of hpt370_lostirq_timeout() since hwif->ide_dma_end() called from
         the driver's interrupt handler later does all its work.

      hpt366: merge HPT37x speedproc handlers · 26ccb802
      Sergei Shtylyov authored
      Continue with the driver rewrite:
      
      - move the interrupt twiddling code from the speedproc handlers into the
          init_hwif_hpt366 which allows to merge the two HPT37x speedproc handlers
          into one;
      
      - get rid of in init_hpt366 which solely consists of the duplicate code, then
          fold init_hpt37x() into init_chipset_hpt366();
      
      - fix hpt3xx_tune_drive() to always set the PIO mode requested, not the best
          possible one, change hpt366_config_drive_xfer_rate() accordingly, simplify
          it a bit;
      
      - group all the DMA related code together init_hwif_hpt366(), and generally
          clean up and beautify it.

      hpt366: cache channel's MCR address · abc4ad4c
      Sergei Shtylyov authored
      Begin the real driver redesign. For the starters:
      
      - cache the offset of the IDE channel's MISC. control registers which are used
         throughout the driver in hwif->select_data;
      
      - only touch the relevant MCR when detecting the cable type on HPT374's
         function 1;
      
      - make HPT36x's speedproc handler look the same way as HPT37x ones; fix the
         PIO timing register mask for HPT37x.
      
      - rename all the HPT3xx register related variables consistently; clean up the
         whitespace.

      hpt366: switch to using pci_get_slot · b4586715
      Sergei Shtylyov authored
      Switch to using pci_get_slot() to get to the function 1 of HPT36x/374 chips --
      there's no need for the driver itself to walk the list of the PCI devices, and
      it also forgets to check the bus number of the device found.

      hpt366: print the real chip name at startup · 90778574
      Sergei Shtylyov authored
      - Rework the driver setup code so that it prefixes the driver startup
        messages with the real chip name.
      
      - Print the measured f_CNT value and the DPLL setting for non-HPT3xx
        chips as well.
      
      - Claim the extra 240 bytes of I/O space for all chips, not only for
        those having PCI device ID of 0x0004.

      hpt366: rework rate filtering · e139b0b0
      Sergei Shtylyov authored
      - Rework hpt3xx_ratemask() and hpt3xx_ratefilter() so that the former
        returns the max.  mode computed at the load time and doesn't have to do
        bad Ultra33 drive list lookups anymore; remove the duplicate code from
        the latter function.  Move the quirky drive list lookup into
        hpt3xx_quirkproc() where it should have been from the start...
      
      - Disable UltraATA/100 for HPT370 by default as the 33 MHz ATA clock
        being used does not allow for it, and this *greatly* increases the
        transfer speed.
      
      - Save some space by using byte-wide fields in struct hpt_info; switch to
        reading the 8-bit PCI revision ID reg.  only, not the whole 32-bit reg.
      
      - Start incrementing the driver version number with each patch (should
        have been done from the first one posted).
