      ide: remove hwif->autodma and drive->autodma · 9ff6f72f
      Bartlomiej Zolnierkiewicz 提交于
      * hpt34x.c: disable DMA masks for HPT345
        (hwif->autodma is zero so DMA won't be enabled anyway).
      
      * trm290.c: disable IDE_HFLAG_TRUST_BIOS_FOR_DMA flag
        (hwif->autodma is zero so DMA won't be enabled anyway).
      
      * 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)

      PCI: Change all drivers to use pci_device->revision · 44c10138
      Auke Kok 提交于
      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.

      serverworks: always tune CSB6 · b740d884
      Bartlomiej Zolnierkiewicz 提交于
      Switch the driver to always program DMA/PIO timings and set device transfer
      mode instead of trusting BIOS on CSB6 controllers (libata pata_serverworks.c
      driver is also doing things this way and there were no problems reported so
      far).  While doing conversion I noticed that the old code had many issues:
      
      * the code was assuming that hwif->dma_status is always valid
        (which obviously isn't true if hwif->dma_base == NULL)
      
      * value of "(ultra_timing >> (4*unit)) & ~(0xF0)" expression wasn't checked
        to fit into udma_modes[5]
      
      * code validating DMA timings didn't validate corresponding PIO timings
      
      * extra CSB5 PIO register wasn't validated et all
      
      * hwif->ide_dma_off_quietly() is always called before ide_set_dma() (which in
        turn calls hwif->speedproc() method - svwks_tune_chipset() in this case)
        so the code depending on DMA capable bit of DMA status to be set was never
        executed (=> the code was never validating DMA timings despite actually
        enabling DMA if the PIO timings were OK!)
      
      * on resume driver dependend entirely on BIOS to restore timings and set
        transfer mode on the device
      
      While at it:
      
      There is no need to read PIO/MWDMA timings now so don't do it.

      It turns out from customer reports to Red Hat and some PCI dumps that the

      fools the code.
      
      For the RAID class case skip the oem setup and don't trust the BIOS data.
      We then tune from scratch and this sorts it out. (This has been confirmed
      on an afflicted IBM blade)

        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)

        config_chipset_for_pio() contained numerous bugs when selecting PIO mode

          before using them

          (moreover wrong cycle times were used for PIO0/1/5)
      
        - 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)

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
