* pata_legacy: fix io/irq mismatchMikael Pettersson2007-03-061-1/+1
| | | | | | | | | | | | | | | | | | | pata_legacy fails to detect the disk on my old ISA/VLB 486: it starts to probe io=0x1f0 ctr=0x3f6 irq=15, complains loudly about IDENTIFYs timing out, and finally fails. (Sorry I couldn't capture the kernel's boot messages.) It turns out that the driver's mapping from io to irq in legacy_irq[] is wrong: index 0 for io=0x1f0 has irq=15 but should have irq=14, and index 1 for io=0x170 has irq=14 but should have irq=15. This is confirmed by a comparison with include/asm-i386/ide.h:ide_default_irq(). This patch swaps the first two elements in legacy_irq[], which makes pata_legacy work on my 486.

* [libata] pata_{legacy,sc1200,sl82c105}: add missing hooksJeff Garzik2007-03-031-0/+18
| | | | | | | | | Alan Cox noticed several hooks in pata_* drivers were missing, when he authored his ->cable_detect hook patches. This patch extracts just those fixes from Alan's patches, adding the necessary hooks (usually ->freeze, ->thaw, and ->post_internal_cmd) to the drivers. Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | This is the first preparation to doing the !IORDY cases properly. Further diffs will then add the needed logic to do it right.

* libata: add another IRQ calls (libata drivers)Akira Iguchi2007-02-091-0/+14
| | | | | | | | | | | | | | | | | | 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.

* libata: convert to iomapTejun Heo2007-02-091-46/+55
| | | | | | | | | | | | | | | | 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.

* libata: update libata LLDs to use devresTejun Heo2007-02-091-38/+13Star
| | | | | | | | | | | | | | | | | 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.

* [PATCH] libata: add missing sht->slave_destroyTejun Heo2006-11-291-0/+1
| | | | | | | | Many LLDs are missing sht->slave_destroy. The method is mandatory to support device warm unplugging (echo 1 > /sys/.../delete). Without it, libata might access released scsi device. Signed-off-by: Tejun Heo <htejun@gmail.com>
