* ata: use CONFIG_PM_SLEEP instead of CONFIG_PM where applicable in host driversBartlomiej Zolnierkiewicz2014-05-091-1/+1
| | | | | | | | | | | | | | | | | | | | This patch fixes host drivers to use CONFIG_PM_SLEEP instead of CONFIG_PM where applicable. Benefits of this change: * unused code is not being compiled in for CONFIG_PM=y, CONFIG_PM_SLEEP=n and CONFIG_PM_RUNTIME=y configurations * easier transition to use struct dev_pm_ops and SIMPLE_DEV_PM_OPS() in the future * more consistent code (there are host drivers which are using the correct CONFIG_PM_SLEEP checks already) The patch leaves the core libata code and ->port_[suspend,resume] support in sata_[inic162x,nv,sil24].c alone for now.

Common parts are factored into __ata_sff_port_intr() and __ata_sff_interrupt() and used by sff and bmdma interrupt routines. All BMDMA drivers now use ata_bmdma_interrupt() or ata_bmdma_port_intr() while all non-BMDMA SFF ones use ata_sff_interrupt() or ata_sff_port_intr().

* sata_sis: convert to slave_linkTejun Heo2009-09-081-50/+25
| | | | | | | | | | | | | | | | | | | During introduction of slave_link, sata_sis slipped through the crack and left with ad-hoc merged SCR access. As SCR status was shared for both the master and slave devices, when only one of the device is online, libata EH would think both are online but would only get valid device signature for the actually present one, which in turn trigger the probing safety net mechanism and make EH retry causing large delay during boot. This patch converts sata_sis to slave_link mechanism.

| | | | | | | | | | | | | | | | | | | sis_scr_cfg_read() can't access SError and was incorrectly returning -1 instead of -EINVAL. This went unnoticed because SError used to be cleared in @postreset() and it didn't care about how scr_read() failed but commit ac371987 moved SError clearing into sata_link_resume() and SCR access failure other than -EINVAL is considered an error condition and exposes the incorrect return value bug as detection failure. Fix it. Also, scsi_scr_cfg_write() was incorrectly returning 0 after it ignored the request to write to SError. Make it also return -EINVAL. This was bisected and reported by Patrick McHardy.

* libata: rename SFF functionsTejun Heo2008-04-171-3/+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>
* libata: implement and use ops inheritanceTejun Heo2008-04-171-21/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* libata: implement and use SHT initializersTejun Heo2008-04-171-15/+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>

* libata: clean up SFF init messTejun Heo2007-05-111-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The intention of using port_mask in SFF init helpers was to eventually support exoctic configurations such as combination of legacy and native port on the same controller. This never became actually necessary and the related code always has been subtly broken one way or the other. Now that new init model is in place, there is no reason to make common helpers capable of handling all corner cases. Exotic cases can simply dealt within LLDs as necessary. This patch removes port_mask handling in SFF init helpers. SFF init helpers don't take n_ports argument and interpret it into port_mask anymore. All information is carried via port_info. n_ports argument is dropped and always two ports are allocated. LLD can tell SFF to skip certain port by marking it dummy. Note that SFF code has been treating unuvailable ports this way for a long time until recent breakage fix from Linus and is consistent with how other drivers handle with unavailable ports. This fixes 1-port legacy host handling still broken after the recent native mode fix and simplifies SFF init logic. The following changes are made... * ata_pci_init_native_host() and ata_init_legacy_host() both now try to initialized whatever they can and mark failed ports dummy. They return 0 if any port is successfully initialized. * ata_pci_prepare_native_host() and ata_pci_init_one() now doesn't take n_ports argument. All info should be specified via port_info array. Always two ports are allocated. * ata_pci_init_bmdma() exported to be used by LLDs in exotic cases. * port_info handling in all LLDs are standardized - all port_info arrays are const stack variable named ppi. Unless the second port is different from the first, its port_info is specified as NULL (tells libata that it's identical to the last non-NULL port_info). * pata_hpt37x/hpt3x2n: don't modify static variable directly. Make an on-stack copy instead as ata_piix does. * pata_uli: It has 4 ports instead of 2. Don't use ata_pci_prepare_native_host(). Allocate the host explicitly and use init helpers.

* libata: update libata LLDs to use devresTejun Heo2007-02-091-23/+10
| | | | | | | | | | | | | | | | | Update libata LLDs to use devres. Core layer is already converted to support managed LLDs. This patch simplifies initialization and fixes many resource related bugs in init failure and detach path. For example, all converted drivers now handle ata_device_add() failure gracefully without excessive resource rollback code. As most resources are released automatically on driver detach, many drivers don't need or can do with much simpler ->{port|host}_stop(). In general, stop callbacks are need iff port or host needs to be given commands to shut it down. Note that freezing is enough in many cases and ports are automatically frozen before being detached.

* sata_sis: Support for PATA supportsAlan2007-02-091-9/+25
| | | | | | | | | | | | This is quick rework of the patch Uwe proposed but using Kconfig not ifdefs and user selection to sort out PATA support. Instead of ifdefs and requiring the user to select both drivers the SATA driver selects the PATA one. For neatness I've also moved the extern into the function that uses it.

* [PATCH] sata_sis: support SiS966/966LUwe Koziolek2007-02-091-25/+54
| | | | | | | | | | | | The SiS966/966L has different PCI-IDs for native mode and AHCI mode. The SiS966 supports four SATA ports only in native mode. Added additional PCI-ID 0x0183 for SiS965/965L. this patch is based on the code from David Wang from SiS Corporation published on SiS Website.

* [PATCH] sata_sis: slave support on SiS965Uwe Koziolek2006-12-011-5/+12
| | | | | | | | | | | | SiS965 and SiS180 chips must support slave mode, SiS965L and SiS964 chips must not support slave mode. SCR_STATUS for SATA ports in powerdown state fixed. Now returning 0x0113 instead of 0x0117. Avoids problem on detecting sata_sis controller. Signed-off-by: Uwe Koziolek <uwe.koziolek@gmx.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [PATCH] sata_sis: fix flags handling for the secondary portTejun Heo2006-10-311-11/+10
| | | | | | | | | | | | | | | | | | | | sis_init_one() modifies probe_ent->port_flags after allocating and initializing it using ata_pci_init_native_mode(). This makes port_flags for the secondary port (probe_ent->pinfo2->flags) go out of sync resulting in misdetection of device due to incorrectly initialized SCR access flag. This patch make probe_ent alloc/init happen after the final port flags value is determined. This is fragile but probe_ent and all the related mess are scheduled to go away soon for exactly this reason. We just need to hold everything together till then. This has been spotted and diagnosed and tested by Patrick McHardy.
