* 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.

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: NTejun Heo <htejun@gmail.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>

Correct handling of SRST reset sequences. After an SRST it is undefined whether the drive has gone back to PIO0. In order to talk safely we should talk slowly and carefully until we know. Thus when we do the reset if the controller has a pio setup method we call it to flip back to PIO 0 and a known state. After the reset completes the identify will then be done at the safe speed and the drive/controller will pick suitable faster modes and reconfigure the controller to these timings. As a side effect it means we force the controller to PIO 0 as we bring it up which fixes funnies on a few systems where the BIOS firmware leaves us in an interesting choice of modes, or embedded boxes with no firmware which come up in random states. For smart controllers there is nothing to do - they know about this internally.

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: NTejun Heo <htejun@gmail.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>

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.

HPA detection message is printed only during initial configuration. HPA unlocked message is printed only during initial configuration or unlocking results in different size. * Instead of using sectors returned in TF of SET_MAX, re-read IDENTIFY data as that's the value the device is going to use. * It's called early during ata_dev_configure() as IDENTIFY data might change after resizing.

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: NTejun Heo <htejun@gmail.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>
