After more than two years it's time to remove them finally Who: Thomas Gleixner <tglx@linutronix.de> + +--------------------------- + +What: fakephp and associated sysfs files in /sys/bus/pci/slots/ +When: 2011 +Why: In 2.6.27, the semantics of /sys/bus/pci/slots was redefined to + represent a machine's physical PCI slots. 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> |
