* PCI: fix -Wakpm warnings in pci_pm_init debug outputJesse Barnes2008-10-201-2/+2

* PCI: connect struct pci_dev to struct pci_slotAlex Chiang2008-10-202-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | The introduction of struct pci_slot (f46753c5e354b857b20ab8e0fe7b25) added a struct pci_slot pointer to struct pci_dev, but we forgot to associate the two. Connect the two structs together; the interesting portions of the object lifetimes are: - when a new pci_slot is created, connect it to the appropriate pci_dev's. A single pci_slot may be associated with multiple pci_dev's, e.g. any multi-function PCI device. - when a pci_slot is released, look for all the pci_dev's it was associated with, and set their pci_slot pointers to NULL - when a pci_dev is created, look for slots to associate with. Note -- when a pci_dev is released, we don't need to do any bookkeeping, since pci_slot's do not have pointers to pci_dev's.

* x86/PCI: irq and pci_ids patch for Intel Ibex Peak DeviceIDsSeth Heasley2008-10-202-5/+12
| | | | | | | | | | | | | | | | This patch updates the Intel Ibex Peak (PCH) LPC and SMBus Controller DeviceIDs. The LPC Controller ID is set by Firmware within the range of 0x3b00-3b1f. This range is included in pci_ids.h using min and max values, and irq.c now has code to handle the range (in lieu of 32 additions to a SWITCH statement). The SMBus Controller ID is a fixed-value and will not change.

* PCI PM: Introduce function pci_wake_from_d3Rafael J. Wysocki2008-10-202-0/+23
| | | | | | | | | | | | | | | | | | | | | | | Many device drivers use the following sequence of statements to enable the device to wake up the system while being in the D3_hot or D3_cold low power state: pci_enable_wake(pdev, PCI_D3hot, 1); pci_enable_wake(pdev, PCI_D3cold, 1); However, the second call is not necessary if the first one succeeds (the ordering of the statements above doesn't matter here) and it may even be harmful, because we are not supposed to enable PME# after the wake-up power has been enabled for the device. To allow drivers to overcome this problem, introduce function pci_wake_from_d3() that will enable the device to wake up the system from any of D3_hot and D3_cold as long as the wake-up from at least one of them is supported.

* PCI: remove dynids.use_driver_dataMilton Miller2008-10-205-6/+1
| | | | | | | | | | | | | | | | The driver flag dynids.use_driver_data is almost consistently not set, and causes more problems than it solves. It was initially intended as a flag to indicate whether a driver's usage of driver_data had been carefully inspected and was ready for values from userspace. That audit was never done, so most drivers just get a 0 for driver_data when new IDs are added from userspace via sysfs. So remove the flag, allowing drivers to see the data directly (a followon patch validates the passed driver_data value against what the drivers expect).

In v9fs_inode_from_fid(), the function p9mode2unixmode() is used, but for all devices it initially returns S_IFBLK, then uses v9fs_get_inode() to initialise a new inode, then finally uses v9fs_stat2inode(), which would determine whether the inode is a block or character device. However, at that point init_special_inode() had already decided to use the block device functions, so even if the inode's mode is turned to a character device, the block functions are still used to operate on them. The attached patch simply calls init_special_inode() again for devices after parsing device node data in v9fs_stat2inode() so that the proper functions are used.

This code performs protocol marshalling/unmarshalling using printf like strings to represent protocol elements. It is my intent to use them to replace the current functions in conv.c as well as the p9_create_* functions.

One for dealing with user buffers and the other for dealing with kernel buffers. There is a tremendous amount of code duplication in the otherwise identical versions of these functions.

| * | | 9p: make rpc code common and rework flush codeEric Van Hensbergen2008-10-175-313/+316
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code moves the rpc function to the common client base, reorganizes the flush code to be more simple and stable, and makes the necessary adjustments to the underlying transports to adapt to the new structure. This reduces the overall amount of code duplication between the transports and should make adding new transports more straightforward. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
| * | | 9p: use the rcall structure passed in the request in trans_fd read_workEric Van Hensbergen2008-10-171-63/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks the read_work function to enable it to directly use a passed in rcall structure. This should help allow us to remove unnecessary copies in the future. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
| * | | 9p: apply common request code to trans_fdEric Van Hensbergen2008-10-174-172/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Apply the now common p9_req_t structure to the fd transport. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
| * | | 9p: apply common tagpool handling to trans_fdEric Van Hensbergen2008-10-171-34/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Simplify trans_fd by using new common client tagpool structure. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
| * | | 9p: move request management to client codeEric Van Hensbergen2008-10-173-127/+238
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The virtio transport uses a simplified request management system that I want to use for all transports. This patch adapts and moves the exisiting code for managing requests to the client common code. Later patches will apply these mechanisms to the other transports.

| * | | 9p: eliminate callback complexityEric Van Hensbergen2008-10-171-83/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current trans_fd rpc mechanisms use a dynamic callback mechanism which introduces a lot of complexity which only accomodates a single special case. This patch removes much of that complexity in favor of a simple exception mechanism to deal with flushes. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
| * | | 9p: consolidate mux_rpc and request structureEric Van Hensbergen2008-10-171-46/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, trans_fd has two structures (p9_req and p9_mux-rpc) which contain mostly duplicate data. This patch consolidates these two structures and removes p9_mux_rpc. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
