* [libata] Remove ->port_disable() hookJeff Garzik2007-10-12

* [libata] add ACPI cable detect APIAlan Cox2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | Combined from two Alan Cox patches: 1) libata: ACPI checks for 80wire cable We can use the ACPI mode information with several drivers as a hint to cable type. If the ACPI mode set by the BIOS is faster than UDMA33 then we know the BIOS thinks there are 80wire cables. If it doesn't set such a mode or it has no ACPI method then we get no further information and can rely on existing approaches Introduce the function headers needed. Null it out for non ACPI boxes Signed-off-by: Alan Cox <alan@redhat.com> 2) libata: ACPI checks for 80wire cable Provide actual methods for checking if the ACPI support thinks the cable is 80wire, or doesn't know Signed-off-by: Alan Cox <alan@redhat.com> Combined into a single changeset and Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [libata] Remove ->irq_ack() hook, and ata_dummy_irq_on()Jeff Garzik2007-10-12
| | | | | | | | | | | | | * ->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() Signed-off-by: Jeff Garzik <jeff@garzik.org>

* ata_piix: disallow UDMA 133 on ICH5 & ICH7Christian Lamparter2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is another outstanding issue with ata_piix.c. Intel has never officially supported anything faster than PATA 100MB/s. But, the ata_piix.c driver "define" the ICH5 & ICH7 as UDMA6 (aka 133MB/s) capable. [ Well, no one has probably noticed it before, because there is bug in do_pata_set_dmamode... Just look at libata_atapiix_enable_real_udma133.patch and you'll see what wrong with it. ] Here are Intel's datasheets for the affected chipsets: ICH5 Datasheet: http://www.intel.com/design/chipsets/datashts/252516.htm (See note on page 183: "... the ICH5 supports reads at the maximum rate of 100MB/s.") ICH7 Datasheet: http://www.intel.com/design/chipsets/datashts/307013.htm (See first note on page 190: "... the ICH7 supports reads at the maximum rate of 100MB/s.") They are two different ways to deal with it: - Either - 1. replace all ich_pata_133 with ich_pata_100. (libata_atapiix_disable_udma6.diff - diff from 2.6.22 ) - Or - 2. keep all ich_pata_133 and fix the bug in "do_pata_set_dmamode". (libata_atapiix_enable_real_udma133.patch - diff from 2.6.22) If there are any concerns about the safety of the patch patch: http://lkml.org/lkml/2007/7/6/292 (It was already tested by an Intel employee, but I guess a bit more user input is necessary here... ) This patch implements 1.

* libata: Correct IORDY handlingAlan Cox2007-10-12
| | | | | | | | | | | | | | | | 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.

* libata-link: update hotplug to handle PMP linksTejun Heo2007-10-12
| | | | | | | | | | 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>
* libata-link: update EH to deal with PMP linksTejun Heo2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | 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>
* libata-link: update ata_scsi_error() to handle PMP linksTejun Heo2007-10-12

* libata-link: add PMP linksTejun Heo2007-10-12
| | | | | | | | | | | | | | | | | | 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>

* libata-link: implement and use link/device iteratorsTejun Heo2007-10-12
| | | | | | | | | | | | | | | | | 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.

* libata-link: introduce ata_linkTejun Heo2007-10-12
| | | | | | | | | | | | | | | | | | | 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.
