2008-04-18ide: remove broken/dangerous HDIO_[UNREGISTER,SCAN]_HWIF ioctls (take 3)Bartlomiej Zolnierkiewicz1-1/+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.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+75
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!
