Now that libata has slave_link, there's no need to keep ugly merged SCR access. Drop it and use slave_link instead. This results in simpler code and much better separate link handling for master and slave. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-09-29libata: make SCR access ops per-linkTejun Heo1-4/+11
Logically, SCR access ops should take @link; however, there was no compelling reason to convert all SCR access ops when adding @link abstraction as there's one-to-one mapping between a port and a non-PMP link. However, that assumption won't hold anymore with the scheduled addition of slave link. Make SCR access ops per-link.

2008-05-30ata_piix: fix macbook ich8m problemsTejun Heo1-3/+4
ICH8M on macbooks are peculiar in that some of them lock up when the second port is enabled, some return bogus values on SIDPR access while yet others hang on SIDPR access. Also, the ich8m_apple_sata entry was wrongly added below generic ich8m entry making it virtually useless. This patch works around macbook ich8m problems by * moving ich8m_apple_sata entry above generic ich8m entry * dropping PIIX_FLAG_SIDPR from ich8m_apple_sata * adding subsystem 106b:00a1 as ich8m_apple_sata Reported and tested by MATSUBAYASHI.

2008-04-17libata: implement and use sata_std_hardreset()Tejun Heo1-26/+1
Implement sata_std_hardreset(), which simply wraps around sata_link_hardreset(). sata_std_hardreset() becomes new standard hardreset method for sata_port_ops and sata_sff_hardreset() moves from ata_base_port_ops to ata_sff_port_ops, which is where it really belongs. ata_is_builtin_hardreset() is added so that both ata_std_error_handler() and ata_sff_error_handler() skip both builtin hardresets if SCR isn't accessible. piix_sidpr_hardreset() in ata_piix.c is identical to sata_std_hardreset() in functionality and got replaced with the standard function.

2008-04-17libata: move generic hardreset code from sata_sff_hardreset() to ↵Tejun Heo1-1/+1
sata_link_hardreset() sata_sff_hardreset() contains link readiness wait logic which isn't SFF specific. Move that part into sata_link_hardreset(), which now takes two more parameters - @online and @check_ready. Both are optional. The former is out parameter for link onlineness after reset. The latter is used to wait for link readiness after hardreset. Users of sata_link_hardreset() is updated to use new funtionality and ahci_hardreset() is updated to use sata_link_hardreset() instead of sata_sff_hardreset(). This doesn't really cause any behavior change. Signed-off-by: Tejun Heo <htejun@gmail.com>
2008-04-17libata: rename SFF functionsTejun Heo1-3/+3
SFF functions have confusing names. Some have sff prefix, some have bmdma, some std, some pci and some none. Unify the naming by... * SFF functions which are common to both BMDMA and non-BMDMA are prefixed with ata_sff_. * SFF functions which are specific to BMDMA are prefixed with ata_bmdma_. * SFF functions which are specific to PCI but apply to both BMDMA and non-BMDMA are prefixed with ata_pci_sff_. * SFF functions which are specific to PCI and BMDMA are prefixed with ata_pci_bmdma_. * Drop generic prefixes from LLD specific routines. For example, bfin_std_dev_select -> bfin_dev_select. The following renames are noteworthy. ata_qc_issue_prot() -> ata_sff_qc_issue() ata_pci_default_filter() -> ata_bmdma_mode_filter() ata_dev_try_classify() -> ata_sff_dev_classify() This rename is in preparation of separating SFF support out of libata core layer. This patch strictly renames functions and doesn't introduce any behavior difference. Signed-off-by: Tejun Heo <htejun@gmail.com>

2008-04-17ata_piix: don't attach to ICH6M in ahci modeTejun Heo1-23/+20
ata_piix when attached to ICH6M in AHCI mode doesn't provide any benefit over using ahci and has detection problems. Don't let ata_piix claim ICH6M if it's in AHCI mode. This change makes ICH6R the only one which ata_piix can attach to even when it's in ahci mode which is necessary as some devices don't work properly under ahci mode. Drop PIIX_FLAG_AHCI and match the controller directly so that piix_disable_ahci() is called only for it. This change makes PIIX_SCC no longer used and it gets dropped too. This fixes bz 9491.

2008-04-17libata: make reset related methods proper port operationsTejun Heo1-16/+5
Currently reset methods are not specified directly in the ata_port_operations table. If a LLD wants to use custom reset methods, it should construct and use a error_handler which uses those reset methods. It's done this way for two reasons. First, the ops table already contained too many methods and adding four more of them would noticeably increase the amount of necessary boilerplate code all over low level drivers. Second, as ->error_handler uses those reset methods, it can get confusing. ie. By overriding ->error_handler, those reset ops can be made useless making layering a bit hazy. Now that ops table uses inheritance, the first problem doesn't exist anymore. The second isn't completely solved but is relieved by providing default values - most drivers can just override what it has implemented and don't have to concern itself about higher level callbacks. In fact, there currently is no driver which actually modifies error handling behavior. Drivers which override ->error_handler just wraps the standard error handler only to prepare the controller for EH. I don't think making ops layering strict has any noticeable benefit. This patch makes ->prereset, ->softreset, ->hardreset, ->postreset and their PMP counterparts propoer ops. Default ops are provided in the base ops tables and drivers are converted to override individual reset methods instead of creating custom error_handler. * ata_std_error_handler() doesn't use sata_std_hardreset() if SCRs aren't accessible. sata_promise doesn't need to use separate error_handlers for PATA and SATA anymore. * softreset is broken for sata_inic162x and sata_sx4. As libata now always prefers hardreset, this doesn't really matter but the ops are forced to NULL using ATA_OP_NULL for documentation purpose. * pata_hpt374 needs to use different prereset for the first and second PCI functions. This used to be done by branching from hpt374_error_handler(). The proper way to do this is to use separate ops and port_info tables for each function. Converted.

2008-04-17libata: implement and use ops inheritanceTejun Heo1-135/+14
libata lets low level drivers build ata_port_operations table and register it with libata core layer. This allows low level drivers high level of flexibility but also burdens them with lots of boilerplate entries. This becomes worse for drivers which support related similar controllers which differ slightly. They share most of the operations except for a few. However, the driver still needs to list all operations for each variant. This results in large number of duplicate entries, which is not only inefficient but also error-prone as it becomes very difficult to tell what the actual differences are. This duplicate boilerplates all over the low level drivers also make updating the core layer exteremely difficult and error-prone. When compounded with multi-branched development model, it ends up accumulating inconsistencies over time. Some of those inconsistencies cause immediate problems and fixed. Others just remain there dormant making maintenance increasingly difficult. To rectify the problem, this patch implements ata_port_operations inheritance. To allow LLDs to easily re-use their own ops tables overriding only specific methods, this patch implements poor man's class inheritance. An ops table has ->inherits field which can be set to any ops table as long as it doesn't create a loop. When the host is started, the inheritance chain is followed and any operation which isn't specified is taken from the nearest ancestor which has it specified. This operation is called finalization and done only once per an ops table and the LLD doesn't have to do anything special about it other than making the ops table non-const such that libata can update it. libata provides four base ops tables lower drivers can inherit from - base, sata, pmp, sff and bmdma. To avoid overriding these ops accidentaly, these ops are declared const and LLDs should always inherit these instead of using them directly. After finalization, all the ops table are identical before and after the patch except for setting .irq_handler to ata_interrupt in drivers which didn't use to. The .irq_handler doesn't have any actual effect and the field will soon be removed by later patch. * sata_sx4 is still using old style EH and currently doesn't take advantage of ops inheritance.

2008-04-17libata: implement and use SHT initializersTejun Heo1-15/+1
libata lets low level drivers build scsi_host_template and register it to the SCSI layer. This allows low level drivers high level of flexibility but also burdens them with lots of boilerplate entries. This patch implements SHT initializers which can be used to initialize all the boilerplate entries in a sht. Three variants of them are implemented - BASE, BMDMA and NCQ - for different types of drivers. Note that entries can be overriden by putting individual initializers after the helper macro. All sht tables are identical before and after this patch. Signed-off-by: Tejun Heo <htejun@gmail.com>
2008-04-17libata: normalize port_info, port_operations and sht tablesTejun Heo1-6/+7
Over the time, port info, ops and sht structures developed quite a bit of inconsistencies. This patch updates drivers. * Enable/disable_pm callbacks added to all ahci ops tables. * Every driver for SFF controllers now uses ata_sff_port_start() instead of ata_port_start() unless the driver has custom implementation. * Every driver for SFF controllers now uses ata_pci_default_filter() unless the driver has custom implementation. * Removed an odd port_info->sht initialization from ata_piix.c. Likely a merge byproduct. * A port which has ATA_FLAG_SATA set doesn't need to set cable_detect to ata_cable_sata(). Remove it from via and mv port ops. * Some drivers had unnecessary .max_sectors initialization which is ignored and was missing .slave_destroy callback. Fixed. * Removed unnecessary sht initializations port_info's. * Removed onsolete scsi device suspend/resume callbacks from pata_bf54x. * No reason to set ata_pci_default_filter() and bmdma functions for PIO-only drivers. Remove those callbacks and replace ata_bmdma_irq_clear with ata_noop_irq_clear. * pata_platform sets port_start to ata_dummy_ret0. port_start can just be set to NULL. * sata_fsl supports NCQ but was missing qc_defer. Fixed. * pata_rb600_cf implements dummy port_start. Removed. Signed-off-by: Tejun Heo <htejun@gmail.com>
2008-02-23PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki1-1/+1
During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: Rafael J.

2008-01-23ata_piix: implement SIDPR SCR accessTejun Heo1-4/+247
For ICH8, SCRs can be accessed using index and data register pair located at BAR 5. This patch implements support for it such that PHY status, errors and hardreset are available for those controllers. This is the only case where two devices on a PATA channel have access to SCRs and creates a unique problem of mapping two SCRs to one link. Note that this is different from PMP case in that they aren't quite separate links - e.g. softreset resets both devices. This problem is worked around by merging the SCR values. To upper layer, it looks like there is a single link with one set of SCRs but with two devices. This works well enough for PHY event, error reporting and hardreset. Supporting hardreset is important because in rare cases SATA devices fail to recover without it after PHY errors.

2008-01-23ata_piix: convert to prepare - activate initializationTejun Heo1-42/+37
ata_piix requires more configuration during initialization than most other SFF compliant controllers and one-go initialzation with ata_pci_one() is too rigid.
