2007-10-12[libata] struct pci_dev related cleanupsJeff Garzik1-19/+14
* remove pointless pci_dev_to_dev() wrapper. Just directly reference the embedded struct device like everyone else does. * pata_cs5520: delete cs5520_remove_one(), it was a duplicate of ata_pci_remove_one() * linux/libata.h: don't bother including linux/pci.h, we don't need it. Simply declare 'struct pci_dev' and assume interested parties will include the header, as they should be doing anyway. * linux/libata.h: consolidate all CONFIG_PCI declarations into a single location in the header.

2007-10-12libata: use ata_exec_internal() for PMP register accessTejun Heo1-8/+0
PMP registers used to be accessed with dedicated accessors ->pmp_read and ->pmp_write. During reset, those callbacks are called with the port frozen so they should be able to run without depending on interrupt delivery. To achieve this, they were implemented polling. However, as resetting the host port makes the PMP to isolate fan-out ports until SError.X is cleared, resetting fan-out ports while port is frozen doesn't buy much additional safety. This patch updates libata PMP support such that PMP registers are accessed using regular ata_exec_internal() mechanism and kills ->pmp_read/write() callbacks. The following changes are made. * PMP access helpers - sata_pmp_read_init_tf(), sata_pmp_read_val(), sata_pmp_write_init_tf() are folded into sata_pmp_read/write() which are now standalone PMP register access functions. * sata_pmp_read/write() returns err_mask instead of rc. This is consistent with other functions which issue internal commands and allows more detailed error reporting. * ahci interrupt handler is modified to ignore BAD_PMP and spurious/illegal completion IRQs while reset is in progress. These conditions are expected during reset. Signed-off-by: Tejun Heo <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>
2007-10-12libata: implement ATA_PFLAG_RESETTINGTejun Heo1-0/+1
Implement ATA_PFLAG_RESETTING. This flag is set while reset is in progress. It's set before prereset is called and cleared after reset fails or postreset is finished. This flag itself doesn't have any function. It will be used by LLDs to tell whether reset is in progress if it needs to behave differently during reset.

2007-10-12libata: Add a drivers/ide style DMA disableAlan Cox1-0/+6
This is useful when debugging, handling problem systems, or for distributions just to get the system installed so it can be sorted out later. This is a bit smarter than the old IDE one and lets you do libata.dma=0 Disable all PATA DMA like old IDE libata.dma=1 Disk DMA only libata.dma=2 ATAPI DMA only libata.dma=4 CF DMA only (or combinations thereof - 0,1,3 being the useful ones I suspect) (I've split CF as it seems to be a seperate case of pain and suffering different to the others and caused by assorted PIO wired adapters etc) Signed-off-by: Alan Cox <[email protected]> [edited to work on SATA too, changing name from 'pata_dma' to 'dma'] Signed-off-by: Jeff Garzik <[email protected]>
2007-10-12libata: add human-readable error value decodingRobert Hancock1-0/+9
This adds human-readable decoding of the ATA status and error registers (similar to what drivers/ide does) as well as the SATA Serror register to libata error handling output. This prevents the need to pore through standards documents to figure out the meaning of the bits in these registers when looking at error reports. Some bits that drivers/ide decoded are not decoded here, since the bits are either command-dependent or obsolete, and properly parsing them would add too much complexity.

2007-10-12libata-pmp: implement Port Multiplier supportTejun Heo1-0/+19
Implement Port Multiplier support. To support PMP, a LLDD has to supply ops->pmp_read() and pmp_write(). If non-null, ->pmp_attach and ->pmp_detach are called on PMP attach and detach, respectively. ->pmp_read/write() can be called while the port is frozen, so they must be implemented by polling. This patch supplies several helpers to ease ->pmp_read/write() implementation. Also, irq_handler and error_handler must be PMP aware. Most of PMP aware EH can be done by calling ata_pmp_do_eh() with appropriate methods. PMP EH uses separate set of reset methods and this patch implements standard prereset, hardreset and postreset methods. This patch only implements PMP support. The next patch will integrate PMP into the reset of libata and thus enable PMP support. Signed-off-by: Tejun Heo <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>

2007-10-12libata-pmp-prep: implement sata_async_notification()Tejun Heo1-2/+2
AN serves multiple purposes. For ATAPI, it's used for media change notification. For PMP, for downstream PHY status change notification. Implement sata_async_notification() which demultiplexes AN. To avoid unnecessary port events, ATAPI AN is not enabled if PMP is attached but SNTF is not available.

2007-10-12libata-pmp-prep: implement ATA_LFLAG_DISABLEDTejun Heo1-0/+3

2007-10-12libata-pmp-prep: implement ATA_LFLAG_NO_RETRYTejun Heo1-0/+1

2007-10-12libata-pmp-prep: implement ATA_LFLAG_NO_SRST, ASSUME_ATA and ASSUME_SEMBTejun Heo1-0/+4
Some links on some PMPs locks up on SRST and/or report incorrect device signature. Implement ATA_LFLAG_NO_SRST, ASSUME_ATA and ASSUME_SEMB to handle these quirky links. NO_SRST makes EH avoid SRST. ASSUME_ATA and SEMB forces class code to ATA and SEMB_UNSUP respectively. Note that SEMB isn't currently supported yet so the _UNSUP variant is used.

2007-10-12libata-pmp-prep: implement qc_defer helpersTejun Heo1-0/+8
Implement ap->nr_active_links (the number of links with active qcs), ap->excl_link (pointer to link which can be used by ->qc_defer and is cleared when a qc with ATA_QCFLAG_CLEAR_EXCL completes), and ata_link_active(). These can be used by ->qc_defer() to implement proper command exclusion. This set of helpers seem enough for both sil24 (ATAPI exclusion needed) and cmd-switching PMP.

2007-10-12libata-pmp-prep: implement ops->qc_defer()Tejun Heo1-0/+6
Controllers which support PMP have various restrictions on which combinations of commands are allowed to what number of devices concurrently. This patch implements ops->qc_defer() which determines whether a qc can be issued at the moment or should be deferred. If the function returns ATA_DEFER_LINK, the qc will be deferred until a qc completes on the link. If ATA_DEFER_PORT, until a qc completes on any link. The defer conditions are advisory and in general ATA_DEFER_LINK can be considered as lower priority deferring than ATA_DEFER_PORT. ops->qc_defer() replaces fixed ata_scmd_need_defer(). For standard NCQ/non-NCQ exclusion, ata_std_qc_defer() is implemented. ahci and sata_sil24 are converted to use ata_std_qc_defer(). ops->qc_defer() is heavier than the original mechanism because full qc is prepped before determining to defer it, but various information is needed to determine defer conditinos and fully translating a qc is the only way to supply such information in generic manner. IMHO, this shouldn't cause any noticeable performance issues as * for most cases deferring occurs rarely (except for NCQ-aware cmd-switching PMP) * translation itself isn't that expensive * once deferred the command won't be repeated until another command completes which usually is a very long time cpu-wise.

Make ata_dev_try_classify() take a pointer to ata_device instead of ata_port/port_number combination for consistency and add @present argument. @present indicates whether the device seems present during reset. It's the result of TF access during softreset and link onlineness during hardreset. @present will be used to improve diagnostic failure handling.

2007-10-12libata: move EH repeat reporting into ata_eh_report()Tejun Heo1-2/+3
EH is sometimes repeated without any error or action. For example, this happens when probing IDENTIFY fails because of a phantom device. In these cases, all the repeated EH does is making sure there is no unhandled error or pending action and return. This repeation is necessary to avoid losing any event which occurred while EH was in progress. Unfortunately, this dry run causes annonying "EH pending after completion" message. This patch moves the repeat reporting into ata_eh_report() such that it's more compact and skipped on dry runs.

2007-10-12libata: implement and use ata_port_desc() to report port configurationTejun Heo1-2/+10
Currently, port configuration reporting has the following problems. * iomapped address is reported instead of raw address * report contains irrelevant fields or lacks necessary fields for non-SFF controllers. * host->irq/irq2 are there just for reporting and hacky. This patch implements and uses ata_port_desc() and ata_port_pbar_desc(). ata_port_desc() is almost identical to ata_ehi_push_desc() except that it takes @ap instead of @ehi, has no locking requirement, can only be used during host initialization and " " is used as separator instead of ", ". ata_port_pbar_desc() is a helper to ease reporting of a PCI BAR or an offsetted address into it. LLD pushes whatever description it wants using the above two functions. The accumulated description is printed on host registration after "[S/P]ATA max MAX_XFERMODE ". SFF init helpers and ata_host_activate() automatically add descriptions for addresses and irq respectively, so only LLDs which isn't standard SFF need to add custom descriptions. In many cases, such controllers need to report different things anyway. Signed-off-by: Tejun Heo <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>

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.

2007-10-12[libata] Remove ->irq_ack() hook, and ata_dummy_irq_on()Jeff Garzik1-4/+0
* ->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().

2007-10-12libata: Correct IORDY handlingAlan Cox1-1/+1
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.

2007-10-12libata-link: add PMP linksTejun Heo1-6/+47
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 <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>

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.
