PCI: Remove the fakephp driver
The fakephp driver was scheduled for removal in 2011.
Fakephp presented /sys/bus/pci/slots/.../power files for every PCI
function. Writing "0" to one of these files logically removed the device
from the system. The PCI core now provides the same functionality with
/sys/bus/pci/devices/.../remove.

The change in semantics - had userspace implications, as the hotplug core no longer allowed - drivers to create multiple sysfs files per physical slot (required - for multi-function devices, e.g.). fakephp was seen as a developer's - tool only, and its interface changed. Too late, we learned that - there were some users of the fakephp interface. - - In 2.6.30, the original fakephp interface was restored. At the same - time, the PCI core gained the ability that fakephp provided, namely - function-level hot-remove and hot-add. - - Since the PCI core now provides the same functionality, exposed in: - - /sys/bus/pci/rescan - /sys/bus/pci/devices/.../remove - /sys/bus/pci/devices/.../rescan - - there is no functional reason to maintain fakephp as well. - - We will keep the existing module so that 'modprobe fakephp' will - present the old /sys/bus/pci/slots/... interface for compatibility, - but users are urged to migrate their applications to the API above. - - After a reasonable transition period, we will remove the legacy - fakephp interface. -Who: Alex Chiang <achiang@hp.com> - ---------------------------- - What: CONFIG_RFKILL_INPUT When: 2.6.33 Why: Should be implemented in userspace, policy daemon. |
