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.
