      Use menuconfig objects: IDE · e0ff9cd1
      Jan Engelhardt authored
      Use menuconfigs instead of menus, so the whole menu can be disabled at once
      instead of going through all options.

      ide: remove ide_use_dma() · 122ab088
      Bartlomiej Zolnierkiewicz authored
      ide_use_dma() duplicates a lot of ide_max_dma_mode() functionality
      and as all users of ide_use_dma() were converted to use ide_tune_dma()
      now it is possible to add missing checks to ide_tune_dma() and remove
      ide_use_dma() completely, so do it.
      
      There should be no functionality changes caused by this patch.

      sl82c105: add speedproc() method and MWDMA0/1 support · 46cedc9b
      Sergei Shtylyov authored
      Add the speedproc() method for setting transfer modes, modify config_for_dma()
      to call it and use ide_max_dma_mode() to select the best DMA mode.
      Add support for the multiword DMA modes 0 and 1, using the upper half of the
      'drive_data' field to store the DMA timings to program into the drive control
      register when DMA is turned on for real.

      sis5513: PIO mode setup fixes · 6b8cf772
      Bartlomiej Zolnierkiewicz authored
      * limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt
        to program PIO5 by config_art_rwp_pio() could result in incorrect PIO
        timings being programmed and possibly the data corruption (for < ATA100
        family chipsets PIO0 timings were used, for ATA100 and ATA100a - the random
        content of test1 variable was used, for ATA133 - MWDMA0 timings were used)
      
      * BUG() in sis5513_tune_chipset() if somebody tries to force unsupported PIO5,
        also cleanup this function a bit while at it
      
      * add comment about PIO0 timings for < ATA100 family chipsets
      
      * remove open-coded best PIO mode selection from config_art_rwp_pio(),
        it contained numerous bugs:
      
        - it didn't check for validity of id->eide_pio_modes and id->eide_pio_iordy
          before using them
      
        - it tried to found out maximum PIO mode basing on minimum IORDY cycle time
          (moreover wrong cycle times were used for PIO1/5)
      
        - it was overriding PIO blacklist and conservative PIO "downgrade" done
          by ide_get_best_pio_mode()
      
      * use sis5513_tune_drive() instead of config_art_rwp_pio()
        in sis5513_config_xfer_rate() so the correct PIO mode is also set
        on drive even if the device is not IORDY/DMA capable
      
      * config_art_rwp_pio() was always setting the best possible mode and not
        the wanted one - fix it and move ide_get_best_pio_mode() call to
        config_chipset_for_pio()
      
      * don't use ide_find_best_mode() in config_chipset_for_pio(), it was being
        overriden by config_art_rwp_pio() for the host timings anyway + we need to
        set the same PIO mode on the device and the host
      
      * pass correct "pio" argument (255 instead of 5) to sis5513_tune_drive() call
        in sis5513_config_xfer_rate() so the best PIO mode is set on the drive
        and not PIO4

      serverworks: PIO mode setup fixes · 9445de76
      Bartlomiej Zolnierkiewicz authored
      * limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt
        to program PIO5 by svwks_tune_chipset() could result in incorrect PIO
        timings being programmed and possibly the data corruption (it seems that
        the minimum possible values were used but I lack the datasheets to be sure)
      
      * select best PIO mode in svwks_tune_drive() and not in svwks_tune_chipset()
        when doing PIO autotuning (pio == 255)
      
      * don't try to tune PIO in config_chipset_for_dma() as ide_dma_enable() could
        return 1 if DMA was previously enabled (svwks_config_drive_xfer_rate()
        takes care of PIO tuning if no suitable DMA mode is found)
      
      * remove config_chipset_for_pio() and use svwks_tune_drive() instead,
        config_chipset_for_pio() contained numerous bugs when selecting PIO mode
        (luckily it was only used for devices limited to PIO by capabilities/BIOS):
      
        - it didn't check for validity of id->eide_pio_modes and id->eide_pio_iordy
          before using them

        - it was overriding PIO blacklist and conservative PIO "downgrade" done
          by ide_get_best_pio_mode()
      
        - if the max drive PIO was PIO5 then XFER_PIO_0/XFER_PIO_SLOW was selected
          (XFER_PIO_SLOW is not supported by svwks_tune_chipset() so the result
           was the same as if using XFER_PIO_5 => wrong PIO timings were set)
      
        - it was overriding drive->current_speed

      pdc202xx_old: rewrite mode programming code (v2) · 4fce3164
      Bartlomiej Zolnierkiewicz authored
      This patch is based on the documentation (I would like to thank Promise
      for it) and also partially on the older vendor driver.
      
      Rewrite mode programming code:
      
      * disable 66MHz clock in pdc202xx_tune_chipset() so it is correctly disabled
        even if both devices on the channel are not DMA capable and after reset
      
      * enable/disable IORDY and PREFETCH bits in pdc202xx_tune_chipset()
        as they need to be setup correctly also for PIO only devices, plus IORDY
        wasn't disabled for non-IORDY devices and PREFETCH wasn't disabled for
        ATAPI devices
      
      * remove dead code for setting SYNC_ERDDY_EN bits from config_chipset_for_dma()
        (driver sets ->autotune to 1 so PIO modes are always programmed => lower
         nibble of register A never equals 4 => "chipset_is_set" is always true)
      
      * enable PIO mode programming for all ATAPI devices
        (it was limited to ->media == ide_cdrom devices)
      
      * remove extra reads of registers A/B/C, don't read register D et all
      
      * do clearing / programming of registers A/B/C in one go
        (gets rid of extra PCI config space read/write cycle)
      
      * set initial values of drive_conf/AP/BP/CP variables to zero
        (paranoia for the case when PCI reads fail)
      
      * remove XFER_UDMA6 to XFER_UDMA5 remapping case - it can't happen
        (ide_rate_filter() takes care of it)
      
      * fix XFER_MW_DMA0 timings (they were overclocked, use the official ones)
      
      * fix bitmasks for clearing bits of register B:
      
        - when programming DMA mode bit 0x10 of register B was cleared which
          resulted in overclocked PIO timing setting (iff PIO0 was used)
      
        - when programming PIO mode bits 0x18 weren't cleared so suboptimal
          timings were used for PIO1-4 if PIO0 was previously set (bit 0x10)
          and for PIO0/3/4 if PIO1/2 was previously set (bit 0x08)
      
      * add FIXME comment about missing locking for 66MHz clock register
      
      Also while at it:
      
      * remove unused defines
      
      * do a few cosmetic / CodingStyle fixes
      
      * bump driver version
      
      v2:
      * in pdc202xx_tune_chipset() the old content of drive configuration
        registers is used only by the debugging code so cover "drive_conf"
        PCI registers read by #if PDC202XX_DEBUG_DRIVE_INFO
        (Noticed by Sergei Shtylyov)

      ucc_geth: eliminate max-speed, change interface-type to phy-connection-type · 4e19b5c1
      Kim Phillips authored
      It was agreed that phy-connection-type was a better name for
      the interface-type property, so this patch renames it.
      
      Also, the max-speed property name was determined too generic,
      and is therefore eliminated in favour of phy-connection-type
      derivation logic.
      
      includes corrections to copyright text.

      Turns out we have an old version of firmware that stores the mac address
      in 'mac-address' as a string instead of a byte array. All versions that
      use local-mac-address should have it as byte array, so no need to do
      string parsing for that case.

      SLUB: CONFIG_LARGE_ALLOCS must consider MAX_ORDER limit · cfbf07f2
      Christoph Lameter authored
      Take MAX_ORDER into consideration when determining KMALLOC_SHIFT_HIGH.
      Otherwise we may run into a situation where we attempt to create general
      slabs larger than MAX_ORDER.

      i386: fix voyager build · 6a3ee3d5
      Jeremy Fitzhardinge authored
      This adds an smp_ops for voyager, and hooks things up appropriately.  This is
      the first baby-step to making subarch runtime switchable.
