      ide: remove IDE_*_REG macros · 23579a2a
      Bartlomiej Zolnierkiewicz authored
      * Add IDE_{ALTSTATUS,IREASON,BCOUNTL,BCOUNTH}_OFFSET defines.
      
      * Remove IDE_*_REG macros - this results in more readable
        and slightly smaller code.
      
      There should be no functional changes caused by this patch.

      scc_pata.c: do setup itself instead of ide_setup_pci_device() · 3d53ba87
      Akira Iguchi authored
      scc_pata has the different BAR configuration and using ide_setup_pci_device()
      is inappropriate. 
      
      (ide_setup_pci_device() expects a normal PCI IDE controller with
      BAR0..BAR3 either non-existant or being primary/secondary port bases
      in I/O space.)
      
      This patch do all needed setup itself instead of calling ide_setup_pci_device().

      ide: remove broken/dangerous HDIO_[UNREGISTER,SCAN]_HWIF ioctls (take 3) · 93de00fd
      Bartlomiej Zolnierkiewicz authored
      hdparm explicitely marks HDIO_[UNREGISTER,SCAN]_HWIF ioctls as DANGEROUS
      and given the number of bugs we can assume that there are no real users:
      
      * DMA has no chance of working because DMA resources are released by
        ide_unregister() and they are never allocated again.
      
      * Since ide_init_hwif_ports() is used for ->io_ports[] setup the ioctls
        don't work for almost all hosts with "non-standard" (== non ISA-like)
        layout of IDE taskfile registers (there is a lot of such host drivers).
      
      * ide_port_init_devices() is not called when probing IDE devices so:
        - drive->autotune is never set and IDE host/devices are not programmed
          for the correct PIO/DMA transfer modes (=> possible data corruption)
        - host specific I/O 32-bit and IRQ unmasking settings are not applied
          (=> possible data corruption)
        - host specific ->port_init_devs method is not called (=> no luck with
          ht6560b, qd65xx and opti621 host drivers)
      
      * ->rw_disk method is not preserved (=> no HPT3xxN chipsets support).
      
      * ->serialized flag is not preserved (=> possible data corruption when
         using icside, aec62xx (ATP850UF chipset), cmd640, cs5530, hpt366
         (HPT3xxN chipsets), rz1000, sc1200, dtc2278 and ht6560b host drivers).
      
      * ->ack_intr method is not preserved (=> needed by ide-cris, buddha,
        gayle and macide host drivers).
      
      * ->sata_scr[] and sata_misc[] is cleared by ide_unregister() and it
        isn't initialized again (SiI3112 support needs them).
      
      * To issue an ioctl() there need to be at least one IDE device present
        in the system.
      
      * ->cable_detect method is not preserved + it is not called when probing
        IDE devices so cable detection is broken (however since DMA support is
        also broken it doesn't really matter ;-).
      
      * Some objects which may have already been freed in ide_unregister()
        are restored by ide_hwif_restore() (i.e. ->hwgroup).
      
      * ide_register_hw() may unregister unrelated IDE ports if free ide_hwifs[]
        slot cannot be found.
      
      * When IDE host drivers are modular unregistered port may be re-used by
        different host driver that owned it first causing subtle bugs.
      
      Since we now have a proper warm-plug support remove these ioctls,
      then remove no longer needed:
      - ide_register_hw() and ide_hwif_restore() functions
      - 'init_default' and 'restore' arguments of ide_unregister()
      - zeroeing of hwif->{dma,extra}_* fields in ide_unregister()
      
      As an added bonus IDE core code size shrinks by ~3kB (x86-32).
      
      v2:
      * fix ide_unregister() arguments in cleanup_module() (Andrew Morton).
      
      v3:
      * fix ide_unregister() arguments in palm_bk3710.c.

      * Add ->cable_detect method to ide_hwif_t.
      
      * Call the new method in ide_init_port() if:
        - the host supports UDMA modes > UDMA2 ('hwif->ultra_mask & 78')
        - DMA initialization was successful (if hwif->dma_base is not set
          ide_init_port() sets hwif->ultra_mask to zero)
        - "idex=ata66" is not used ('hwif->cbl != ATA_CBL_PATA40_SHORT')
      
      * Convert PCI host drivers to use ->cable_detect method.
      
      While at it:
      
      * Factor out cable detection to separate functions (if not already done).
      
      * hpt366.c/it8213.c/slc90e66.c:

      ide: remove hwif->autodma and drive->autodma · 9ff6f72f
      Bartlomiej Zolnierkiewicz authored
      * hpt34x.c: disable DMA masks for HPT345

      * Check noautodma global variable instead of drive->autodma in ide_tune_dma().
      
        This fixes handling of "ide=nodma" kernel parameter for icside, ide-cris,
        au1xxx-ide, pmac, it821x, jmicron, sgiioc4 and siimage host drivers.
      
      * Remove hwif->autodma (it was not checked by IDE core code anyway) and
        drive->autodma (was set by all host drivers - except HPT345/TRM290 special
        cases - unless "ide=nodma" was used).
      
      While at it:
      - remove needless printk() from icside.c
      - remove stale FIXME/comment from ide-probe.c
      - don't force DMA off if PCI bus-mastering had to be enabled in setup-pci.c
        (this setting was always later over-ridden by host drivers anyway)

      need to re-tune PIO because PIO and DMA timings are shared.

      ide: move ide_config_drive_speed() calls to upper layers (take 2) · 88b2b32b
      Bartlomiej Zolnierkiewicz authored
      * Convert {ide_hwif_t,ide_pci_device_t}->host_flag to be u16.
      
      * Add IDE_HFLAG_POST_SET_MODE host flag to indicate the need to program 
        the host for the transfer mode after programming the device.  Set it
        in au1xxx-ide, amd74xx, cs5530, cs5535, pdc202xx_new, sc1200, pmac
        and via82cxxx host drivers.
      
      * Add IDE_HFLAG_NO_SET_MODE host flag to indicate the need to completely
        skip programming of host/device for the transfer mode ("smart" hosts).
        Set it in it821x host driver and check it in ide_tune_dma().
      
      * Add ide_set_pio_mode()/ide_set_dma_mode() helpers and convert all
        direct ->set_pio_mode/->speedproc users to use these helpers.
      
      * Move ide_config_drive_speed() calls from ->set_pio_mode/->speedproc
        methods to callers.
      
      * Rename ->speedproc method to ->set_dma_mode, make it void and update
        all implementations accordingly.
      
      * Update ide_set_xfer_rate() comments.
      
      * Unexport ide_config_drive_speed().
      
      v2:
      * Fix issues noticed by Sergei:
        - export ide_set_dma_mode() instead of moving ->set_pio_mode abuse wrt
          to setting DMA modes from sc1200_set_pio_mode() to do_special()
        - check IDE_HFLAG_NO_SET_MODE in ide_tune_dma()
        - check for (hwif->set_pio_mode) == NULL in ide_set_pio_mode()
        - check for (hwif->set_dma_mode) == NULL in ide_set_dma_mode()
        - return -1 from ide_set_{pio,dma}_mode() if ->set_{pio,dma}_mode == NULL
        - don't set ->set_{pio,dma}_mode on it821x in "smart" mode
        - fix build problem in pmac.c
        - minor fixes in au1xxx-ide.c/cs5530.c/siimage.c
        - improve patch description
      
      Changes in behavior caused by this patch:
      - HDIO_SET_PIO_MODE ioctl would now return -ENOSYS for attempts to change
        PIO mode if it821x controller is in "smart" mode
      - removal of two debugging printk-s (from cs5530.c and sc1200.c)
      - transfer modes 0x00-0x07 passed from user space may be programmed twice on
        the device (not really an issue since 0x00 is not supported correctly by
        any host driver ATM, 0x01 is not supported at all and 0x02-0x07 are invalid)

        the maximum PIO mode supported by the host), also add ide_set_max_pio()
        wrapper for ide_set_pio() to use for auto-tuning.  Convert users of

        do_special(), set_using_pio(), ide_hwif_restore() and ide_set_pio() as
        a direct users of ->tuneproc.
