When we get an SDB FIS with the 'N' bit set, we should send an event to user space to indicate that there has been a media change. This will be done via the scsi device. Signed-off-by: Kristen Carlson Accardi <kristen.c.accardi@intel.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

Add support for issuing ATA_16 passthru commands to ATAPI devices managed by libata. It requires the previous CDB length fix patch. A boot/module parameter, "atapi_passthru16=0" can be used to globally disable this feature, if ever desired. tj: restructured __ata_scsi_queuecmd() according to Jeff's suggestion.

Debugging a report of a problem with an ancient solid state disk showed up some problems in the IORDY handling 1. We check the wrong bit to see if the device has IORDY 2. Even then some ancient creaking piles of crap don't support SETXFER at all. The cases it fixes are obscure and the risk of side effects is slight but possible. This also moves us slightly closer to supporting original MFM/RLL disks with libata. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

Update hotplug to handle PMP links. When PMP is attached, the PMP number corresponds to C of SCSI H:C:I:L. While at it, change argument to ata_find_dev() to @devno from @id to avoid confusion with SCSI device ID. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

Update ata_eh_autopsy(), ata_eh_report(), ata_eh_revalidate_and_attach() and ata_eh_recover() to deal with PMP links. ata_eh_autopsy() and ata_eh_report() updates are straightforward. They just repeat the same operation over all configured links. The only change to ata_eh_revalidate_and_attach() is avoiding calling ->cable_select() on non-host ports. ata_eh_recover() update is more complex as it first processes all resets and then performs the rest. This is necessary as thawing with some links in unknown state can be dangerous. ehi->action is cleared on successful recovery of a link to avoid repeating recovery due to failures in other links. ata_eh_recover() iterates over only PMP links if PMP is attached, and, on failure, the failing link is returned in @failed_link instead of disabling devices directly. These are to integrate ata_eh_recover() into PMP EH later. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

Add link->pmp, ap->nr_pmp_links, ap->pmp_link[], and implement/update link helpers. printk helpers are updated such that port and link are identifed as 'ataP:' if no PMP is attached, while device is identified as 'ataP.DD:'. If PMP is attached, they become 'ataP:', 'ataP.LL:' and 'ataP.LL' - ie. link and device are identified their PMP number. If PPM is attached (ap->nr_pmp_links != 0), ata_for_each_link() iterates over PMP links, while __ata_for_each_link() iterates over the host link + PMP links. If PMP is not attached (ap->nr_pmp_links == 0), both iterate over only the host link. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

HRST_TO_RESUME and SKIP_D2H_BSY are link attributes. Move them to ata_link->flags. This will allow host and PMP links to have different attributes. ata_port_info->link_flags is added and used by LLDs to specify these flags during initialization.

Multiple links and different number of devices per link should be considered to iterate over links and devices. This patch implements and uses link and device iterators - ata_port_for_each_link() and ata_link_for_each_dev() - and ata_link_max_devices(). This change makes a lot of functions iterate over only possible devices instead of from dev 0 to dev ATA_MAX_DEVICES. All such changes have been examined and nothing should be broken. While at it, add a separating comment before device helpers to distinguish them better from link helpers and others.

Introduce ata_link. It abstracts PHY and sits between ata_port and ata_device. This new level of abstraction is necessary to support SATA Port Multiplier, which basically adds a bunch of links (PHYs) to a ATA host port. Fields related to command execution, spd_limit and EH are per-link and thus moved to ata_link. This patch only defines the host link. Multiple link handling will be added later. Also, a lot of ap->link derefences are added but many of them will be removed as each part is converted to deal directly with ata_link instead of ata_port. This patch introduces no behavior change.

Make sure and not dump reserved areas of device space. Touching some of these causes machine check exceptions on boards like D-Link DGE-550SX. Coding note, used a complex switch statement rather than bitmap because it is easier to relate the block values to the documentation rather than looking at a encoded bitmask.

Currently find_legacy_serial_ports() can find no serial ports on the OPB with flattened device tree. Thus no legacy boot console can be initialized. Just the early udbg console works, which is initialized with udbg_init_44x_as1 on the UART's physical address specified in kernel config. This happens because we look for ns16750 serial devices only and expect opb node to have a device type property. This patch makes it look for ns16550-compatible devices and use of_device_is_compatible() for opb in case device type is not specified.
