2007-05-11libata: clean up SFF init messTejun Heo
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. It's simple enough. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-05-11libata: reimplement suspend/resume support using sdev->manage_start_stopTejun Heo
Reimplement suspend/resume support using sdev->manage_start_stop. * Device suspend/resume is now SCSI layer's responsibility and the code is simplified a lot. * DPM is dropped. This also simplifies code a lot. Suspend/resume status is port-wide now. * ata_scsi_device_suspend/resume() and ata_dev_ready() removed. * Resume now has to wait for disk to spin up before proceeding. I couldn't find easy way out as libata is in EH waiting for the disk to be ready and sd is waiting for EH to complete to issue START_STOP. * sdev->manage_start_stop is set to 1 in ata_scsi_slave_config(). This fixes spindown on shutdown and suspend-to-disk. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-04-28libata: Change prototype of mode_filter to remove ata_port*Alan Cox
With Tejun having added adev->ap some time ago we can get rid of the almost unused port being passed to mode filters. And while we are doing filters, lets turn on the !IORDY filter as well.

2007-04-28libata: dev_config does not need ap and adev passingAlan
It used to be impossible to get from ata_device to ata_port but that is no longer true. Various methods have been cleaned up over time but dev_config still takes both and most users don't need both anyway.

2007-02-09libata: add another IRQ calls (libata drivers)Akira Iguchi
This patch is against each libata driver. Two IRQ calls are added in ata_port_operations. - irq_on() is used to enable interrupts. - irq_ack() is used to acknowledge a device interrupt. In most drivers, ata_irq_on() and ata_irq_ack() are used for irq_on and irq_ack respectively. In some drivers (ex: ahci, sata_sil24) which cannot use them as is, ata_dummy_irq_on() and ata_dummy_irq_ack() are used.

2007-02-09libata: convert to iomapTejun Heo
Convert libata core layer and LLDs to use iomap. * managed iomap is used. Pointer to pcim_iomap_table() is cached at host->iomap and used through out LLDs. This basically replaces host->mmio_base. * if possible, pcim_iomap_regions() is used Most iomap operation conversions are taken from Jeff Garzik <jgarzik@pobox.com>'s iomap branch.

2007-02-09libata: update libata LLDs to use devresTejun Heo
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.

2007-02-09libata: use ata_id_c_string()Tejun Heo

2006-12-04[PATCH] pata_ali: small fixesAlan
Switch to pci_get_bus_and_slot because some x86 systems seem to be handing us a device with dev->bus = NULL. Also don't apply the isa fixup to revision C6 and later of the chip. Really we need to work out wtf is handing us pdev->bus = NULL, but firstly and more importantly we need the drivers working.
