* libata-sff: clean up BMDMA initializationTejun Heo2010-05-191-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When BMDMA initialization failed or BMDMA was not available for whatever reason, bmdma_addr was left at zero and used as an indication that BMDMA shouldn't be used. This leads to the following problems. p1. For BMDMA drivers which don't use traditional BMDMA register, ata_bmdma_mode_filter() incorrectly inhibits DMA modes. Those drivers either have to inherit from ata_sff_port_ops or clear ->mode_filter explicitly. p2. non-BMDMA drivers call into BMDMA PRD table allocation. It doesn't actually allocate PRD table if bmdma_addr is not initialized but is still confusing. p3. For BMDMA drivers which don't use traditional BMDMA register, some methods might not be invoked as expected (e.g. bmdma_stop from ata_sff_post_internal_cmd()). p4. SFF drivers w/ custom DMA interface implement noop BMDMA ops worrying libata core might call into one of them. These problems are caused by the muddy line between SFF and BMDMA and the assumption that all BMDMA controllers initialize bmdma_addr. This patch fixes p1 and p2 by removing the bmdma_addr assumption and moving prd allocation to BMDMA port start. Later patches will fix the remaining issues. This patch improves BMDMA initialization such that * When BMDMA register initialization fails, falls back to PIO instead of failing. ata_pci_bmdma_init() never fails now. * When ata_pci_bmdma_init() falls back to PIO, it clears ap->mwdma_mask and udma_mask instead of depending on ata_bmdma_mode_filter(). This makes ata_bmdma_mode_filter() unnecessary thus resolving p1. * ata_port_start() which actually is BMDMA specific is moved to ata_bmdma_port_start(). ata_port_start() and ata_sff_port_start() are killed. * ata_sff_port_start32() is moved and renamed to ata_bmdma_port_start32(). Drivers which no longer call into PRD table allocation are... pdc_adma, sata_inic162x, sata_qstor, sata_sx4, pata_cmd640 and all drivers which inherit from ata_sff_port_ops. pata_icside sets ->port_start to ATA_OP_NULL as it doesn't need PRD but is a BMDMA controller and doesn't have custom port_start like other such controllers. Note that with the previous patch which makes all and only BMDMA drivers inherit from ata_bmdma_port_ops, this change doesn't break drivers which need PRD table.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There currently are the following looping constructs. * __ata_port_for_each_link() for all available links * ata_port_for_each_link() for edge links * ata_link_for_each_dev() for all devices * ata_link_for_each_dev_reverse() for all devices in reverse order Now there's a need for looping construct which is similar to __ata_port_for_each_link() but iterates over PMP links before the host link. Instead of adding another one with long name, do the following cleanup. * Implement and export ata_link_next() and ata_dev_next() which take @mode parameter and can be used to build custom loop. * Implement ata_for_each_link() and ata_for_each_dev() which take looping mode explicitly. The following iteration modes are implemented. * ATA_LITER_EDGE : loop over edge links * ATA_LITER_HOST_FIRST : loop over all links, host link first * ATA_LITER_PMP_FIRST : loop over all links, PMP links first * ATA_DITER_ENABLED : loop over enabled devices * ATA_DITER_ENABLED_REVERSE : loop over enabled devices in reverse order * ATA_DITER_ALL : loop over all devices * ATA_DITER_ALL_REVERSE : loop over all devices in reverse order This change removes exlicit device enabledness checks from many loops and makes it clear which ones are iterated over in which direction.

* libata: implement and use ops inheritanceTejun Heo2008-04-171-20/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: normalize port_info, port_operations and sht tablesTejun Heo2008-04-171-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* libata: implement and use ata_noop_irq_clear()Tejun Heo2008-04-171-1/+1
| | | | | | | | | | | | | | ->irq_clear() is used to clear IRQ bit of a SFF controller and isn't useful for drivers which don't use libata SFF HSM implementation. However, it's a required callback and many drivers implement their own noop version as placeholder. This patch implements ata_noop_irq_clear and use it to replace those custom placeholders. Also, SFF drivers which don't support BMDMA don't need to use ata_bmdma_irq_clear(). It becomes noop if BMDMA address isn't initialized. Convert them to use ata_noop_irq_clear().

* libata: pata_platform: Support polling-mode configuration.Paul Mundt2007-11-081-7/+28
| | | | | | | | | | | | | | | Some SH boards (old R2D-1 boards) have generally not had working CF under libata, due to both buswidth issues (handled by Aoi Shinkai in 43f4b8c7578b928892b6f01d374346ae14e5eb70), and buggy interrupt controllers. For these sorts of boards simply disabling the IRQ and polling ends up working fine.

* libata: implement and use ata_port_desc() to report port configurationTejun Heo2007-10-121-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
