  • 3957df616   pata_cs5536: ATA driver for Geode companion chip ... Browse Code »

    This is a driver for the ATA controller on the Geode CS5536 companion
    chip. The PCI device ID for this device was previously claimed by
    pata_amd.c but the PIO timings were not correct. This driver also
    works around a bug in some BIOSes that handle unaligned access to the
    PCI config registers poorly. Finally, the driver allows fallback to
    using MSR registers for configuration on BIOSes that are truly
    broken.

  • 7c9ef8e41   AVR32 PATA driver ... Browse Code »

    Updated and simplified driver. Use only register transfer timing for both
    data and register transfers. This gives poorer performance in PIO1 and 2,
    but should not be a problem in PIO3 and 4, correct me if I'm wrong :)

    The driver works very we'll but I still wonder about the interrupts. I have
    an interrupt line, that works nicely when POLLING flag is not set. The
    problem is the number of interrupts that eat away my CPU cycles.

    When using the POLLING flag there seem to be some interrupts that dosen't get
    cleared. Furthermore the device dosen't drive INTRQ high, it stays at 2.5 volts
    and generates a lot of interrupts due to ripple / noise. What to do?

    The HPT343/345 (aka 363) is a bit of a warped device. For many setups you
    need to access the other registers via BAR4 offsets. PIO is now rock
    solid, DMA isn't. Unfortunately the drivers/ide hpt34x driver is
    completely broken so doesn't help further debug.

    Add help info for BLK_DEV_SD referring to its use in
    SATA or PATA driver configurations.

    Add help text for "ATA" indicating that it probably needs
    some SCSI config symbols enabled in order to be useful.

  • 8cdfb29c0   libata/IDE: remove combined mode quirk ... Browse Code »

    Both old-IDE and libata should be able handle all controllers and
    devices found using normal resource reservation methods.

    This eliminates the awful, low-performing split-driver configuration
    where old-IDE drove the PATA portion of a PCI device, in PIO-only mode,
    and libata drove the SATA portion of the /same/ PCI device, in DMA mode.
    Typically vendors would ship SATA hard drive / PATA optical
    configuration, which would lend itself to slow (PIO-only) CD-ROM
    performance.

    For Intel users running in combined mode, it is now wholly dependent on
    your driver choice (potentially link order, if you compile both drivers
    in) whether old-IDE or libata will drive your hardware.

    In either case, you will get full performance from both SATA and PATA
    ports now, without having to pass a kernel command line parameter.

    This is quick rework of the patch Uwe proposed but using Kconfig not
    ifdefs and user selection to sort out PATA support. Instead of ifdefs and
    requiring the user to select both drivers the SATA driver selects the
    PATA one.

    For neatness I've also moved the extern into the function that uses it.

    Add a driver for the IT8213 which is a single channel ICH-ish PATA

    that once I get time to test it all out (probably early January). If
    anyone else needs the drivers/ide driver and wants to do the merge for
    drivers/ide (Bart ??) then I'll forward it.

  • 8cdf92a98   Fix Maple PATA IRQ assignment. ... Browse Code »

    On the Maple board, the AMD8111 IDE is in legacy mode... except that it
    appears on IRQ 20 instead of IRQ 15. For drivers/ide this was handled by
    the architecture's "pci_get_legacy_ide_irq()" function, but in libata we
    just hard-code the numbers 14 and 15.

    This patch provides asm-powerpc/libata-portmap.h which maps the IRQ as
    appropriate, having added a pci_dev argument to the
    ATA_{PRIM,SECOND}ARY_IRQ macros.

    There's probably a better way to do this -- especially if we observe
    that the _only_ case in which this seemingly-generic
    "pci_get_legacy_ide_irq()" function returns anything other than 14 and
    15 for primary and secondary respectively is the case of the AMD8111 on
    the Maple board -- couldn't we handle that with a special case in the
    pata_amd driver, or perhaps with a PCI quirk for Maple to switch it into
    native mode during early boot and assign resources properly?
