2009-06-07ide: preserve Host Protected Area by default (v2)Bartlomiej Zolnierkiewicz1-0/+2
From the perspective of most users of recent systems, disabling Host Protected Area (HPA) can break vendor RAID formats, GPT partitions and risks corrupting firmware or overwriting vendor system recovery tools. Unfortunately the original (kernels < 2.6.30) behavior (unconditionally disabling HPA and using full disk capacity) was introduced at the time when the main use of HPA was to make the drive look small enough for the BIOS to allow the system to boot with large capacity drives. Thus to allow the maximum compatibility with the existing setups (using HPA and partitioned with HPA disabled) we automically disable HPA if any partitions overlapping HPA are detected. Additionally HPA can also be disabled using the "nohpa" module parameter (i.e. "ide_core.nohpa=0.0" to disable HPA on /dev/hda). v2: Fix ->resume HPA support.

2008-04-27ide: add "ignore_cable" parameter (take 2)Bartlomiej Zolnierkiewicz1-5/+10
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).
