* PCI: pciehp: remove pci_dev fieldKenji Kaneshige2009-09-17
| | | | | | | | | Since we have a pointer to pcie_device in struct controller, we don't need a pointer to pci_dev. Acked-by: Alex Chiang <achiang@hp.com> Signed-off-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
* PCI: pciehp: remove crit_sect mutexKenji Kaneshige2009-09-17
| | | | | | | | | | | The crit_sect mutex defined in struct controller is to serialize hot-plug operations against multiple slots under the same bus. But, since PCIe doesnstream port has only one slot at most, it is meaningless and we don't need it.

* PCI ASPM: support L1 onlyKenji Kaneshige2009-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | The definition of the ASPM support field in the Link Capabilities Register had been changed by the "ASPM optionality ECN" as follows: <Before> 00b Reserved 01b L0s Supported 10b Reserved 11b L0s and L1 Supported <After> 00b No ASPM Support 01b L0s Supported 10b L1 Supported 11b L0s and L1 Supported Current linux ASPM driver doesn't enable ASPM if the support field is 00b or 10b. So there is no impact about 00b. But current linux ASPM driver doesn't enable L1 if the support field is 10b. With this patch, 10b (L1 support) is handled properly.

| * Driver Core: devtmpfs - kernel-maintained tmpfs-based /devKay Sievers2009-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Devtmpfs lets the kernel create a tmpfs instance called devtmpfs very early at kernel initialization, before any driver-core device is registered. Every device with a major/minor will provide a device node in devtmpfs. Devtmpfs can be changed and altered by userspace at any time, and in any way needed - just like today's udev-mounted tmpfs. Unmodified udev versions will run just fine on top of it, and will recognize an already existing kernel-created device node and use it. The default node permissions are root:root 0600. Proper permissions and user/group ownership, meaningful symlinks, all other policy still needs to be applied by userspace. If a node is created by devtmps, devtmpfs will remove the device node when the device goes away. If the device node was created by userspace, or the devtmpfs created node was replaced by userspace, it will no longer be removed by devtmpfs. If it is requested to auto-mount it, it makes init=/bin/sh work without any further userspace support. /dev will be fully populated and dynamic, and always reflect the current device state of the kernel. With the commonly used dynamic device numbers, it solves the problem where static devices nodes may point to the wrong devices. It is intended to make the initial bootup logic simpler and more robust, by de-coupling the creation of the inital environment, to reliably run userspace processes, from a complex userspace bootstrap logic to provide a working /dev.

| * Driver core: Add support for compatibility classesJean Delvare2009-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When turning class devices into bus devices, we may need to temporarily add links in sysfs so that user-space applications are not confused. This is done by adding the following API: * Functions to register and unregister compatibility classes. These appear in sysfs at the same location as regular classes, but instead of class devices, they contain links to bus devices. * Functions to create and delete such links. Additionally, the caller can optionally pass a target device to which a "device" link should point (typically that would be the device's parent), to fully emulate the original class device. The i2c subsystem will be the first user of this API, as i2c adapters are being converted from class devices to bus devices.

| * uio: add generic driver for PCI 2.3 devicesMichael S. Tsirkin2009-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a generic uio driver that can bind to any PCI device. First user will be virtualization where a qemu userspace process needs to give guest OS access to the device. Interrupts are handled using the Interrupt Disable bit in the PCI command register and Interrupt Status bit in the PCI status register. All devices compliant to PCI 2.3 (circa 2002) and all compliant PCI Express devices should support these bits. Driver detects this support, and won't bind to devices which do not support the Interrupt Disable Bit in the command register. It's expected that more features of interest to virtualization will be added to this driver in the future. Possibilities are: mmap for device resources, MSI/MSI-X, eventfd (to interface with kvm), iommu. Signed-off-by: Michael S.

| * Driver core: add new device to bus's list before probingAlan Stern2009-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1271) affects when new devices get linked into their bus's list of devices. Currently this happens after probing, and it doesn't happen at all if probing fails. Clearly this is wrong, because at that point quite a few symbolic links have already been created in sysfs. We are committed to adding the device, so it should be linked into the bus's list regardless. In addition, this needs to happen before the uevent announcing the new device gets issued. Otherwise user programs might try to access the device before it has been added to the bus. To fix both these problems, the patch moves the call to klist_add_tail() forward from bus_attach_device() to bus_add_device(). Since bus_attach_device() now does nothing but probe for drivers, it has been renamed to bus_probe_device(). And lastly, the kerneldoc is updated.
