  • It was always set to ata_port_disable(). Removed the hook, and replaced
    the very few ap->ops->port_disable() callsites with direct calls to
    ata_port_disable().

  • * ->irq_ack() is redundant to what the irq handler already
    performs... chk-status + irq-clear. Furthermore, it is only
    called in one place, when screaming-irq-debugging is enabled,
    so we don't want to bother with a hook just for that.

    * ata_dummy_irq_on() is only ever used in drivers that have
    no callpath reaching ->irq_on(). Remove .irq_on hook from
    those drivers, and the now-unused ata_dummy_irq_on()

  • With PCI resource fix up for legacy hosts. We can use the same code
    path to allocate IO resources and initialize host for both legacy and
    native SFF hosts. Only IRQ requesting needs to be different.

    Rename ata_pci_*_native_host() to ata_pci_*_sff_host(), kill all
    legacy specific functions and use the renamed functions instead. This
    simplifies code a lot.

  • Changed PATA handler for PATA-ports used by sata_sis.
    This patch was originally submitted by Jeff Garzik.

    Added PCI-ID 1180 for SiS966 Controller in pata_sis.
    The 1180 mode is fully compatible to other SiS PATA-controller.

    The PCI-ID 1183 is SATA in PATA-emulation, but not fully compatible
    to SiS5513/5518. sata_sis.c is forwarding this ID to pata_sis.
    1183 is not working if simply added to pata_sis.
    This handling fixes issues with SiS968.

  • The intention of using port_mask in SFF init helpers was to eventually
    support exoctic configurations such as combination of legacy and
    native port on the same controller. This never became actually
    necessary and the related code always has been subtly broken one way
    or the other. Now that new init model is in place, there is no reason
    to make common helpers capable of handling all corner cases. Exotic
    cases can simply dealt within LLDs as necessary.

    This patch removes port_mask handling in SFF init helpers. SFF init
    helpers don't take n_ports argument and interpret it into port_mask
    anymore. All information is carried via port_info. n_ports argument
    is dropped and always two ports are allocated. LLD can tell SFF to
    skip certain port by marking it dummy. Note that SFF code has been
    treating unuvailable ports this way for a long time until recent
    breakage fix from Linus and is consistent with how other drivers
    handle with unavailable ports.

    This fixes 1-port legacy host handling still broken after the recent
    native mode fix and simplifies SFF init logic. The following changes
    are made...

    * ata_pci_init_native_host() and ata_init_legacy_host() both now try
    to initialized whatever they can and mark failed ports dummy. They
    return 0 if any port is successfully initialized.

    * ata_pci_prepare_native_host() and ata_pci_init_one() now doesn't
    take n_ports argument. All info should be specified via port_info
    array. Always two ports are allocated.

    * ata_pci_init_bmdma() exported to be used by LLDs in exotic cases.

    * port_info handling in all LLDs are standardized - all port_info
    arrays are const stack variable named ppi. Unless the second port
    is different from the first, its port_info is specified as NULL
    (tells libata that it's identical to the last non-NULL port_info).

    * pata_hpt37x/hpt3x2n: don't modify static variable directly. Make an
    on-stack copy instead as ata_piix does.

    * pata_uli: It has 4 ports instead of 2. Don't use
    ata_pci_prepare_native_host(). Allocate the host explicitly and use
    init helpers. It's simple enough.

  • Somehow the sis_info133 external definition ended up in libata.h and that
    was included by both drivers. However libata.h contains libata-* specific
    internals and clashing defines like DRV_NAME so this makes a mess. Move
    the extern into the C file and remove the warnings

  • This patch is against each libata driver.

    Two IRQ calls are added in ata_port_operations.
    - irq_on() is used to enable interrupts.
    - irq_ack() is used to acknowledge a device interrupt.

    In most drivers, ata_irq_on() and ata_irq_ack() are used for
    irq_on and irq_ack respectively.

    In some drivers (ex: ahci, sata_sil24) which cannot use them
    as is, ata_dummy_irq_on() and ata_dummy_irq_ack() are used.

  • Convert libata core layer and LLDs to use iomap.

    * managed iomap is used. Pointer to pcim_iomap_table() is cached at
    host->iomap and used through out LLDs. This basically replaces
    host->mmio_base.

    * if possible, pcim_iomap_regions() is used

    Most iomap operation conversions are taken from Jeff Garzik
    's iomap branch.

  • Update libata LLDs to use devres. Core layer is already converted to
    support managed LLDs. This patch simplifies initialization and fixes
    many resource related bugs in init failure and detach path. For
    example, all converted drivers now handle ata_device_add() failure
    gracefully without excessive resource rollback code.

    As most resources are released automatically on driver detach, many
    drivers don't need or can do with much simpler ->{port|host}_stop().
    In general, stop callbacks are need iff port or host needs to be given
    commands to shut it down. Note that freezing is enough in many cases
    and ports are automatically frozen before being detached.

  • Static code shouldn't be used from other modules.

    drivers/built-in.o: In function `sis_init_one':
    sata_sis.c:(.text+0x7634cd): undefined reference to `sis_info133'
    sata_sis.c:(.text+0x7634d6): undefined reference to `sis_info133'

    While I was at it, I also moved the prototype of this struct to a header
    file.

  • 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.

  • The SiS966/966L has different PCI-IDs for native mode and AHCI mode.
    The SiS966 supports four SATA ports only in native mode.

    Added additional PCI-ID 0x0183 for SiS965/965L.

    this patch is based on the code from David Wang from SiS Corporation published on SiS Website.

    SiS965L and SiS964 chips must not support slave mode.

  • sis_init_one() modifies probe_ent->port_flags after allocating and
    initializing it using ata_pci_init_native_mode(). This makes port_flags
    for the secondary port (probe_ent->pinfo2->flags) go out of sync resulting
    in misdetection of device due to incorrectly initialized SCR access flag.

    This patch make probe_ent alloc/init happen after the final port flags
    value is determined. This is fragile but probe_ent and all the related
    mess are scheduled to go away soon for exactly this reason. We just need
    to hold everything together till then.

    This has been spotted and diagnosed and tested by Patrick McHardy.

  • The biggest change is that ata_host_set is renamed to ata_host.

    * ata_host_set => ata_host
    * ata_probe_ent->host_flags => ata_probe_ent->port_flags
    * ata_probe_ent->host_set_flags => ata_probe_ent->_host_flags
    * ata_host_stats => ata_port_stats
    * ata_port->host => ata_port->scsi_host
    * ata_port->host_set => ata_port->host
    * ata_port_info->host_flags => ata_port_info->flags
    * ata_(.*)host_set(.*)\(\) => ata_\1host\2()

    The leading underscore in ata_probe_ent->_host_flags is to avoid
    reusing ->host_flags for different purpose. Currently, the only user
    of the field is libata-bmdma.c and probe_ent itself is scheduled to be
    removed.

    ata_port->host is reused for different purpose but this field is used
    inside libata core proper and of different type.
