  • 5b66c829b   ahci, pata_marvell: play nicely together ... Browse Code »

    I've been chasing Jeff about this for months. Jeff added the Marvell
    device identifiers to the ahci driver without making the AHCI driver
    handle the PATA port. This means a lot of users can't use current
    kernels and in most distro cases can't even install.

    This has been going on since March 2008 for the 6121 Marvell, and late 2007
    for the 6145!!!

    This was all pointed out at the time and repeatedly ignored. Bugs assigned
    to Jeff about this are ignored also.

    To quote Jeff in email

    > "Just switch the order of 'ahci' and 'pata_marvell' in
    > /etc/modprobe.conf, then use Fedora's tools regenerate the initrd.

    > See? It's not rocket science, and the current configuration can be
    > easily made to work for Fedora users."

    (Which isn't trivial, isn't end user, shouldn't be needed, and as it usually
    breaks at install time is in fact impossible)

    To quote Jeff in August 2007

    > " mv-ahci-pata
    > Marvell 6121/6141 PATA support. Needs fixing in the 'PATA controller
    > command' area before it is usable, and can go upstream."

    Only he add the ids anyway later and caused regressions, adding a further
    id in March causing more regresions.

    The actual fix for the moment is very simple. If the user has included
    the pata_marvell driver let it drive the ports. If they've only selected
    for SATA support give them the AHCI driver which will run the port a fraction
    faster. Allow the user to control this decision via ahci.marvell_enable as
    a module parameter so that distributions can ship 'it works' defaults and
    smarter users (or config tools) can then flip it over it desired.

    Lots of work needed to bring it up to scratch but it does work so you can
    now use the card. That makes it at least useful, especially as the other
    cardbus cards are usually INIC162x which aren't yet supported well.

  • 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.
