ata: Add and use ata_print_version_once

2011-07-23T21:57:36Z

Use a single mechanism to show driver version. Reduces text a tiny bit too. Remove uses of static int printed_version Add and use ata_print_version(const struct device *, const char *ver) and ata_print_version_once. $ size drivers/ata/built-in.* text data bss dec hex filename 544969 73893 116584 735446 b38d6 drivers/ata/built-in.allyesconfig.ata.o 543870 73893 116592 734355 b34ad drivers/ata/built-in.allyesconfig.print_once.o 141328 14689 4220 160237 271ed drivers/ata/built-in.defconfig.ata.o 141212 14689 4220 160121 27179 drivers/ata/built-in.defconfig.print_once.o Signed-off-by: Joe Perches Signed-off-by: Jeff Garzik

ATA: Don't powerdown Compaq Triflex IDE device on suspend

2011-05-20T00:46:40Z

Don't powerdown Compaq Triflex IDE device on suspend This fixes APM suspend on Compaq Armada 7400. APM BIOS doesn't suspend if IDE is powered down when suspending. The Triflex controller is found only on old Compaq boards, so this patch will hopefully have no side effects. Signed-off-by: Mikulas Patocka Signed-off-by: Jeff Garzik

libata-sff: separate out BMDMA init

2010-05-25T23:40:30Z

Separate out ata_pci_bmdma_prepare_host() and ata_pci_bmdma_init_one() from their SFF counterparts. SFF ones no longer try to initialize BMDMA or set PCI master. Signed-off-by: Tejun Heo Signed-off-by: Jeff Garzik

libata: Pass host flags into the pci helper

2010-03-01T19:58:46Z

This allows parallel scan and the like to be set without having to stop using the existing full helper functions. This patch merely adds the argument and fixes up the callers. It doesn't undo the special cases already in the tree or add any new parallel callers. Signed-off-by: Alan Cox Signed-off-by: Jeff Garzik

libata: rename SFF functions

2008-04-17T19:44:21Z

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

libata: make reset related methods proper port operations

2008-04-17T19:44:18Z

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. Signed-off-by: Tejun Heo

libata: stop overloading port_info->private_data

2008-04-17T19:44:17Z

port_info->private_data is currently used for two purposes - to record private data about the port_info or to specify host->private_data to use when allocating ata_host. This overloading is confusing and counter-intuitive in that port_info->private_data becomes host->private_data instead of port->private_data. In addition, port_info and host don't correspond to each other 1-to-1. Currently, the first non-NULL port_info->private_data is used. This patch makes port_info->private_data just be what it is - private_data for the port_info where LLD can jot down extra info. libata no longer sets host->private_data to the first non-NULL port_info->private_data, @host_priv argument is added to ata_pci_init_one() instead. LLDs which use ata_pci_init_one() can use this argument to pass in pointer to host private data. LLDs which don't should use init-register model anyway and can initialize host->private_data directly. Adding @host_priv instead of using init-register model for LLDs which use ata_pci_init_one() is suggested by Alan Cox. Signed-off-by: Tejun Heo Cc: Alan Cox
