* PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki2008-02-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: Rafael J.

* | PCI: Fix wrong reference counter check for proc_dir_entryKenji Kaneshige2008-02-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix wrong counter check for proc_dir_entry in pci_proc_detach_device(). The pci_proc_detach_device() returns with -EBUSY before calling remove_proc_entry() if the reference counter of proc_dir_entry is not 0. But this check is wrong and pci_proc_detach_device() always fails because the reference counter of proc_dir_entry is initialized with 1 at creating time and decremented in remove_proc_entry(). This bug cause strange behaviour as followings: - Accessing /proc/bus/pci/XXXX/YY file after hot-removing pci adapter card causes kernel panic. - Repeating hot-add/hot-remove of pci adapter card increases files with the same name under /proc/bus/pci/XXXX/ directory. For example: # pwd /proc/bus/pci/0002:09 # ls 01.0 # for i in `seq 5` > do > echo 0 > /sys/bus/pci/slots/0009_0032/power > echo 1 > /sys/bus/pci/slots/0009_0032/power > done # ls 01.0 01.0 01.0 01.0 01.0 01.0 The pci_proc_detach_device() should check if the reference counter is not larger than 1 instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PCI Express ASPM defines a protocol for PCI Express components in the D0 state to reduce Link power by placing their Links into a low power state and instructing the other end of the Link to do likewise. This capability allows hardware-autonomous, dynamic Link power reduction beyond what is achievable by software-only controlled power management. However, The device should be configured by software appropriately. Enabling ASPM will save power, but will introduce device latency. This patch adds ASPM support in Linux. It introduces a global policy for ASPM, a sysfs file /sys/module/pcie_aspm/parameters/policy can control it. The interface can be used as a boot option too. Currently we have below setting: -default, BIOS default setting -powersave, highest power saving mode, enable all available ASPM state and clock power management -performance, highest performance, disable ASPM and clock power management By default, the 'default' policy is used currently. In my test, power difference between powersave mode and performance mode is about 1.3w in a system with 3 PCIE links.

| * PCI: Fix fakephp deadlockIan Abbott2008-02-011-4/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the fakephp driver is used to emulate removal of a PCI device by writing text string "0" to the "power" sysfs attribute file, this causes its parent directory and its contents (including the "power" file) to be deleted before the write operation returns. Unfortunately, it ends up in a deadlock waiting for itself to complete. The deadlock is as follows: sysfs_write_file calls flush_write_buffer which calls sysfs_get_active_two before calling power_write_file in pci_hotplug_core.c via the sysfs store operation. The power_write_file function calls disable_slot in fakephp.c via the slot operation. The disable_slot function calls remove_slot which calls pci_hp_deregister (back in pci_hotplug_core.c) which calls fs_remove_slot which calls sysfs_remove_file to remove the "power" file. The sysfs_remove_file function calls sysfs_hash_and_remove which calls sysfs_addrm_finish which calls sysfs_deactivate. The sysfs_deactivate function sees that something has an active reference on the sysfs_dirent (from the previous call to sysfs_get_active_two back up the call stack somewhere) so waits for the active reference to go away, which is of course impossible. The problem has been present since 2.6.21. This patch breaks the deadlock by queuing work queue items on a single- threaded work queue to remove a slot from sysfs, and to rescan the PCI buses. There is also some protection against disabling a slot that is already being removed.

This is the workaround against Bad DLLP error that sometimes happen during turning power off on the slot which conforms to PCI Express 1.0a spec. The cause of this error seems that PCI Express 1.0a spec doesn't have the following consideration that was added to PCI Express 1.1 spec. "If the port is associated with a hot-pluggable slot (Hot-Plug Capable bit in the Slot Capabilities register set to 1b), and Power Controller Control bit in Slot Control register is 1b(Off), then any transition to DL Inactive must not be considered an error."

| * PCI: Add pci_enable_device_{io,mem} intefacesBenjamin Herrenschmidt2008-02-011-1/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pci_enable_device_bars() interface isn't well suited to PCI because you can't actually enable/disable BARs individually on a device. So for example, if a device has 2 memory BARs 0 and 1, and one of them (let's say 1) has not been successfully allocated by the firmware or the kernel, then enabling memory decoding shouldn't be permitted for the entire device since it will decode whatever random address is still in that BAR 1. So a device must be either fully enabled for IO, for Memory, or for both. Not on a per-BAR basis. This provides two new functions, pci_enable_device_io() and pci_enable_device_mem() to replace pci_enable_device_bars(). The implementation internally builds a BAR mask in order to be able to use existing arch infrastructure.
