(S)ATA drives can be configured for "power-up in standby", a mode whereby a specific "spin up now!" command is required before the first media access. Currently, a drive with this feature enabled can not be used at all with libata, and once in this mode, the drive becomes a doorstop. The older drivers/ide subsystem at least enumerates the drive, so that it can be woken up after the fact from a userspace HDIO_* command, but not libata. This patch adds support to libata for the "power-up in standby" mode where a "spin up now!" command (SET_FEATURES) is needed. With this, libata will recognize such drives, spin them up, and then re-IDENTIFY them if necessary to get a full/complete set of drive features data. Drives in this state are determined by looking for special values in id[2], as documented in the current ATA specs.

Signed-off-by: NAlan Cox <alan@redhat.com> Add support for ignoring the BIOS HPA result (off by default) and setting the disk to the full available size unless already frozen. Tested with various platforms/disks and confirmed to work with the Macintosh (which broke earlier) and ata_piix (breakage due to the LBA48 readback that Tejun fixed). For normal users this brings us, I believe, to feature parity with old IDE (and of course more featured in some areas too). Signed-off-by: NJeff Garzik <jeff@garzik.org>

Convert ahci, sata_sil, sata_sil24, sata_svw, sata_qstor, sata_mv, sata_sx4, sata_vsc and sata_inic162x to new init model. Now that host and ap are available during intialization, functions are converted to take either host or ap instead of low level parameters which were inevitable for functions shared between init and other paths. This simplifies code quite a bit. * init_one()'s now follow more consistent init order * ahci_setup_port() and ahci_host_init() collapsed into ahci_init_one() for init order consistency * sata_vsc uses port_info instead of setting fields manually * in sata_svw, k2_board_info converted to port_info (info is now in port flags). port number is honored now.

Convert sata_via and sata_promise to new init model. Both controllers can have combined configuration (SATA + PATA) and used twisted initialization method (modifying port in ->port_start) to overcome probe_ent limitations. This patch converts both drivers to new init model in which such configuration is natively supported. * promise: Combined pata port now uses separate port_info entry right after the sata counterpart entry. * promise: Controller configuration is discerned using ap->flags. This simplifies init path and makes it look more like other LLDs. * via: Both SATA and PATA ports in vt6421 are represented in their own port_info structure. Tested on PDC20375 (SATA150 TX2plus) [105a:3375] and PDC40775 (SATA 300 TX2plus) [105a:3d73]. Couldn't test via cuz my c3 won't boot the current kernel.

These will be used to convert LLDs to new init model. * Add irq_handler field to port_info. In new init model, requesting IRQ is LLD's responsibility and libata doesn't need to know about irq_handler. Most LLDs can simply register their irq_handler but some need different irq_handler depending on specific chip. The added port_info->irq_handler field can be used by LLDs to select the matching IRQ handler in such cases. * Add ata_dummy_port_info. * Implement ata_pci_prepare_native_host(), a helper to alloc ATA host, acquire all resources and init the host in one go.

Convert native PCI host handling to alloc-init-register model. New function ata_pci_init_native_host() follows the new init model and replaces ata_pci_init_native_mode().

Convert legacy PCI host handling to alloc-init-register model. ata_init_legacy_host(), ata_request_legacy_irqs() and ata_pci_init_bmdma() are separated out and follow the new init model. The two legacy handling functions use separate ata_legacy_devres instead of generic devm_* resources. This reduces devres overhead for legacy hosts which was a bit high because it didn't use PCI/iomap merged resoruces. ata_pci_init_one() is rewritten in terms of the aboved functions but native mode handling is still using the old method. Conversion will be completed when native mode handling is updated. Signed-off-by: NTejun Heo <htejun@gmail.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>

Reorganize ata_host_alloc() and its subroutines into the following three functions. * ata_host_alloc() : allocates host and its ports. shost is not registered automatically. * ata_scsi_add_hosts() : allocates and adds shosts associated with an ATA host. Used by ata_host_register(). * ata_host_register() : takes a fully initialized ata_host structure and registers it to libata layer and probes it. Only ata_host_alloc() and ata_host_register() are exported. ata_device_add() is rewritten using the above functions. This patch does not introduce any observable behavior change. Things worth mentioning. * print_id is assigned at registration time and LLDs are allowed to overallocate ports and reduce host->n_ports during initialization. ata_host_register() will throw away unused ports automatically. * All SCSI host initialization stuff now resides in ata_scsi_add_hosts() in libata-scsi.c, where it should be. * ipr is now the only user of ata_host_init(). Either kill it by converting ipr to use ata_host_alloc() and friends or rename and move it to libata-scsi.c Signed-off-by: NTejun Heo <htejun@gmail.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>

->post_internal_cmd is simplified EH for internal commands. Its primary mission is to stop the controller such that no rogue memory access or other activities occur after the internal command is released. It may provide error diagnostics by setting qc->err_mask but this hasn't been a requirement. To ignore SETXFER failure for CFA devices, libata needs to know whether a command was failed by the device or for any other reason. ie. internal command needs to get AC_ERR_DEV right. This patch makes the following changes to AC_ERR_DEV handling and ->post_internal_cmd semantics to accomodate this need and simplify callback implementation. 1. As long as the correct bits in the result TF registers are set, there is no need to set AC_ERR_DEV explicitly. libata EH core takes care of that for both normal and internal commands. 2. The only requirement for ->post_internal_cmd() is to put the controller into quiescent state. It needs not to set any err_mask. 3. ata_exec_internal_sg() performs minimal error analysis such that AC_ERR_DEV is automatically set as long as result_tf is filled correctly.

There are several registers which describe how the controller is configured. These registers are sometimes implemented as r/w registers which are configured by firmware and get cleared on controller reset or after suspend/resume cycle. ahci saved and restored those values inside ahci_reset_controller() which is a bit messy and doesn't work over suspend/resume cycle. This patch implements ahci_save/restore_initial_config(). The save function is called during driver initialization and saves cap and port_map to hpriv. The restore function is called after the controller is reset to restore the initial values. Sometimes the initial firmware values are inconsistent and need to be fixed up. This is handled by ahci_save_initial_config(). For this, there are two versions of saved registers. One to write back to the hardware register, the other to use during driver operation. This is necessary to keep ahci's behavior unchanged (write back fixed up port_map while keeping cap as-is). This patch makes ahci save the register values once before the first controller reset, not after it's been reset. Also, the same stored values are used written back after each reset, so the register values are properly recovered after suspend/resume cycle.

Promise ATA ports should always be reset by pdc_reset_port() when errors are detected, but the recent error reason decoding update to sata_promise replaced that reset with a freeze. This patch changes the error detection to do a reset again. This makes the error decoding update safer, as it now only adds error decoding without changing any other behaviour.

The READ/WRITE LONG commands are theoretically obsolete, but the majority of drives in existance still implement them. The WRITE_LONG and WRITE_LONG_ONCE commands are of particular interest for fault injection testing -- eg. creating "media errors" at specific locations on a disk. The fussy bit is that these commands require a non-standard sector size, usually 520 bytes instead of 512. This patch adds support to libata for READ/WRITE LONG commands issued via SG_IO/ATA_16.
