* PNP: ide: constify pnp_device_idArvind Yadav2017-08-161-1/+1
| | | | | | | | | pnp_device_id are not supposed to change at runtime. All functions working with pnp_device_id provided by <linux/pnp.h> work with const pnp_device_id. So mark the non-const structs as const. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* PNP: ide/ide-pnp: Use module_pnp_driver to register driverPeter Huewe2015-03-181-13/+1
| | | | | | | | Removing some boilerplate by using module_pnp_driver instead of calling register and unregister in the otherwise empty init/exit functions Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
* ide/ata: Add module.h to the implicit modular usersPaul Gortmaker2011-10-311-0/+1
| | | | | | | | A pending cleanup will mean that module.h won't be implicitly everywhere anymore. Make sure the modular drivers in the ide dir are actually calling out for <module.h> explicitly in advance. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

| | | | | | | | | | | | | | | | | | * Convert host drivers that still use hw_regs_t's chipset field to use the one in struct ide_port_info instead. * Move special handling of ide_pci chipset type from ide_hw_configure() to ide_init_port(). * Remove chipset field from hw_regs_t.

| | | | | | | | | | | | | | | | | | | | | | | | | * Add 'hw_regs_t **hws' argument to ide_device_add[_all]() and convert host drivers + ide_legacy_init_one() + ide_setup_pci_device[s]() to use it instead of calling ide_init_port_hw() directly. [ However if host has > 1 port we must still set hwif->chipset to hint consecutive ide_find_port() call that the previous slot is occupied. ] * Unexport ide_init_port_hw(). v2: * Use defines instead of hard-coded values in buddha.c, gayle.c and q40ide.c.

| | | | | | | | | | ide_find_port() now depends on ->chipset being set for occupied ide_hwifs[] slots so all host drivers have to initialize hwif->chipset properly.

* ide: remove broken/dangerous HDIO_[UNREGISTER,SCAN]_HWIF ioctls (take 3)Bartlomiej Zolnierkiewicz2008-04-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | hdparm explicitely marks HDIO_[UNREGISTER,SCAN]_HWIF ioctls as DANGEROUS and given the number of bugs we can assume that there are no real users: * DMA has no chance of working because DMA resources are released by ide_unregister() and they are never allocated again. * Since ide_init_hwif_ports() is used for ->io_ports[] setup the ioctls don't work for almost all hosts with "non-standard" (== non ISA-like) layout of IDE taskfile registers (there is a lot of such host drivers). * ide_port_init_devices() is not called when probing IDE devices so: - drive->autotune is never set and IDE host/devices are not programmed for the correct PIO/DMA transfer modes (=> possible data corruption) - host specific I/O 32-bit and IRQ unmasking settings are not applied (=> possible data corruption) - host specific ->port_init_devs method is not called (=> no luck with ht6560b, qd65xx and opti621 host drivers) * ->rw_disk method is not preserved (=> no HPT3xxN chipsets support). * ->serialized flag is not preserved (=> possible data corruption when using icside, aec62xx (ATP850UF chipset), cmd640, cs5530, hpt366 (HPT3xxN chipsets), rz1000, sc1200, dtc2278 and ht6560b host drivers). * ->ack_intr method is not preserved (=> needed by ide-cris, buddha, gayle and macide host drivers). * ->sata_scr[] and sata_misc[] is cleared by ide_unregister() and it isn't initialized again (SiI3112 support needs them). * To issue an ioctl() there need to be at least one IDE device present in the system. * ->cable_detect method is not preserved + it is not called when probing IDE devices so cable detection is broken (however since DMA support is also broken it doesn't really matter ;-). * Some objects which may have already been freed in ide_unregister() are restored by ide_hwif_restore() (i.e. ->hwgroup). * ide_register_hw() may unregister unrelated IDE ports if free ide_hwifs[] slot cannot be found. * When IDE host drivers are modular unregistered port may be re-used by different host driver that owned it first causing subtle bugs. Since we now have a proper warm-plug support remove these ioctls, then remove no longer needed: - ide_register_hw() and ide_hwif_restore() functions - 'init_default' and 'restore' arguments of ide_unregister() - zeroeing of hwif->{dma,extra}_* fields in ide_unregister() As an added bonus IDE core code size shrinks by ~3kB (x86-32). v2: * fix ide_unregister() arguments in cleanup_module() (Andrew Morton). v3: * fix ide_unregister() arguments in palm_bk3710.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Make remaining built-in only IDE host drivers modular, add ide-scan-pci.c file for probing PCI host drivers registered with IDE core (special case for built-in IDE and CONFIG_IDEPCI_PCIBUS_ORDER=y) and then take care of the ordering in which all IDE host drivers are probed when IDE is built-in during link time. * Move probing of gayle, falconide, macide, q40ide and buddha (m68k arch specific) host drivers, before PCI ones (no PCI on m68k), ide-cris (cris arch specific), cmd640 (x86 arch specific) and pmac (ppc arch specific). * Move probing of ide-cris (cris arch specific) host driver before cmd640 (x86 arch specific). * Move probing of mpc8xx (ppc specific) host driver before ide-pnp (depends on ISA and none of ppc platform that use mpc8xx supports ISA) and ide-h8300 (h8300 arch specific). * Add "probe_vlb" kernel parameter to cmd640 host driver and update Documentation/ide.txt accordingly. * Make IDE_ARM config option visible so it can also be disabled if needed. * Remove bogus comment from ide.c while at it. v2: * Fix two issues spotted by Sergei: - replace ENOMEM error value by ENOENT in ide-h8300 host driver - fix MODULE_PARM_DESC() in cmd640 host driver Cc: Sergei Shtylyov <sshtylyov@ru.mvista.com> Cc: Mikael Starvik <starvik@axis.com> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Roman Zippel <zippel@linux-m68k.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
