* ide: add __ide_default_irq() inline helperBartlomiej Zolnierkiewicz2008-07-08
| | | | | | | | | | | | Add __ide_default_irq() inline helper and use it instead of ide_default_irq() in ide-probe.c and ns87415.c (all host drivers except IDE PCI ones always setup hwif->irq so it is enough to check only for I/O bases 0x1f0 and 0x170). This fixes post-2.6.25 regression since ide_default_irq() define could shadow ide_default_irq() inline. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
* ide: fix hwif->gendev refcountingBartlomiej Zolnierkiewicz2008-07-05
| | | | | | | | | | | | | | | | | | class->dev_release is called by device_release() iff dev->release is not present so ide_port_class_release() is never called and the last hwif->gendev reference is not dropped. Fix it by removing ide_port_class_release() and get_device() call from ide_register_port() (device_create_drvdata() takes a hwif->gendev reference anyway).

* ide: add "ignore_cable" parameter (take 2)Bartlomiej Zolnierkiewicz2008-04-27
| | | | | | | | | | | | | | | | | | | | | Add "ignore_cable" parameter: * "ide_core.ignore_cable=[interface_number]" boot option if IDE is built-in (i.e. "ide_core.ignore_cable=1" to force ignoring cable for "ide1") * "ignore_cable=[interface_number]" module parameter (for ide_core module) if IDE is compiled as module v2: * Add ide_port_apply_params() helper - use it in ide_device_add_all() and ide_scan_port(). * Make it possible to later disable ignoring cable detection by passing "[interface_number]:0" to /sys/module/ide_core/parameters/ignore_cable (however sysfs interface is not enabled yet since it needs some other IDE changes to make it work reliable).

* ide: add struct ide_dma_ops (take 3)Bartlomiej Zolnierkiewicz2008-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add struct ide_dma_ops and convert core code + drivers to use it. While at it: * Drop "ide_" prefix from ->ide_dma_end and ->ide_dma_test_irq methods. * Drop "ide_" "infixes" from DMA methods. * au1xxx-ide.c: - use auide_dma_{test_irq,end}() directly in auide_dma_timeout() * pdc202xx_old.c: - drop "old_" "infixes" from DMA methods * siimage.c: - add siimage_dma_test_irq() helper - print SATA warning in siimage_init_one() * Remove no longer needed ->init_hwif implementations. v2: * Changes based on review from Sergei: - s/siimage_ide_dma_test_irq/siimage_dma_test_irq/ - s/drive->hwif/hwif/ in idefloppy_pc_intr(). - fix patch description w.r.t. au1xxx-ide changes - fix au1xxx-ide build - fix naming for cmd64*_dma_ops - drop "ide_" and "old_" infixes - s/hpt3xxx_dma_ops/hpt37x_dma_ops/ - s/hpt370x_dma_ops/hpt370_dma_ops/ - use correct DMA ops for HPT302/N, HPT371/N and HPT374 - s/it821x_smart_dma_ops/it821x_pass_through_dma_ops/ v3: * Two bugs slipped in v2 (noticed by Sergei): - use correct DMA ops for HPT374 (for real this time) - handle HPT370/HPT370A properly Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Make ide_hwif_setup_dma() return an error value. * Pass 'const struct ide_port_info *d' instead of 'unsigned long dmabase' to ->init_dma method and make it return an error value. * Rename ide_get_or_set_dma_base() to ide_pci_dma_base(), change ordering of its arguments and then export it. * Export ide_pci_set_master(). * Do complete DMA setup inside ->init_dma method and update ->init_dma users accordingly. * Sanitize code for DMA setup in ide_init_port(). v2: * Fix for CONFIG_BLK_DEV_IDEDMA_PCI=n configs (from Jiri Slaby <jirislaby@gmail.com>): Fix following compiler warning by returning EINVAL: In file included from ANYTHING-INCLUDING-IDE.H:45: include/linux/ide.h: In function ‘ide_hwif_setup_dma’: include/linux/ide.h:1022: warning: no return statement in function returning non-void Cc: Jiri Slaby <jirislaby@gmail.com> Cc: Andrew Morton <akpm@linux-foundation.org> Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* ide: cleanup setting hwif->mmio flagBartlomiej Zolnierkiewicz2008-04-26
| | | | | | | | | | It is no longer needed to set hwif->mmio flag to tell IDE layer to not manage resources so cleanup host drivers that used hwif->mmio flag only for this purpose. Ditto for ide_legacy_init_one(). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
* ide: manage resources for PCI devices in ide_pci_enable() (take 3)Bartlomiej Zolnierkiewicz2008-04-26
| | | | | | | | | | | | | | | | | | | | * Reserve PCI BARs 0-3 (0-1 for single port controllers) in ide_pci_enable() and remove ide_hwif_request_regions() call from ide_device_add_all() (also cleanup resource management in scc_pata host driver). * Fix handling of PCI BAR 4 in ide_pci_enable(), then cleanup ide_iomio_dma() (+ init_hwif_trm290() in trm290 host driver) and remove ide_release[_iomio]_dma(). v2: * Fixup trm290 host driver. v3: * Because of scc_pata host driver changes we need to call pci_request_selected_regions() also in setup_mmio_scc().
