From 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 16 Apr 2005 15:20:36 -0700 Subject: Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip! --- include/linux/8250_pci.h | 2 + include/linux/a.out.h | 268 ++ include/linux/ac97_codec.h | 374 +++ include/linux/acct.h | 201 ++ include/linux/acpi.h | 536 ++++ include/linux/adb.h |

The remainder, termed a + * file handle fragment, is controlled completely by the filesystem. + * The standard helper routines assume that this fragment will contain one or two + * sub-fragments, one which identifies the file, and one which may be used to + * identify the (a) directory containing the file. + * + * In some situations, nfsd needs to get a dentry which is connected into a + * specific part of the file tree. To allow for this, it passes the function + * acceptable() together with a @context which can be used to see if the dentry + * is acceptable. As there can be multiple dentrys for a given file, the filesystem + * should check each one for acceptability before looking for the next. As soon + * as an acceptable one is found, it should be returned. + * + * decode_fh: + * @decode_fh is given a &struct super_block (@sb), a file handle fragment (@fh, @fh_len) + * and an acceptability testing function (@acceptable, @context). It should return + * a &struct dentry which refers to the same file that the file handle fragment refers + * to, and which passes the acceptability test. If it cannot, it should return + * a %NULL pointer if the file was found but no acceptable &dentries were available, or + * a %ERR_PTR error code indicating why it couldn't be found (e.g. %ENOENT or %ENOMEM). + * + * encode_fh: + * @encode_fh should store in the file handle fragment @fh (using at most @max_len bytes) + * information that can be used by @decode_fh to recover the file refered to by the + * &struct dentry @de. If the @connectable flag is set, the encode_fh() should store + * sufficient information so that a good attempt can be made to find not only + * the file but also it's place in the filesystem. This typically means storing + * a reference to de->d_parent in the filehandle fragment. + * encode_fh() should return the number of bytes stored or a negative error code + * such as %-ENOSPC + * + * get_name: + * @get_name should find a name for the given @child in the given @parent directory. + * The name should be stored in the @name (with the understanding that it is already + * pointing to a a %NAME_MAX+1 sized buffer. get_name() should return %0 on success, + * a negative error code or error. + * @get_name will be called without @parent->i_sem held. + * + * get_parent: + * @get_parent should find the parent directory for the given @child which is also + * a directory. In the event that it cannot be found, or storage space cannot be + * allocated, a %ERR_PTR should be returned. + * + * get_dentry: + * Given a &super_block (@sb) and a pointer to a file-system specific inode identifier, + * possibly an inode number, (@inump) get_dentry() should find the identified inode and + * return a dentry for that inode. + * Any suitable dentry can be returned including, if necessary, a new dentry created + * with d_alloc_root. The caller can then find any other extant dentrys by following the + * d_alias links. If a new dentry was created using d_alloc_root, DCACHE_NFSD_DISCONNECTED + * should be set, and the dentry should be d_rehash()ed. + * + * If the inode cannot be found, either a %NULL pointer or an %ERR_PTR code can be returned. + * The @inump will be whatever was passed to nfsd_find_fh_dentry() in either the + * @obj or @parent parameters. + * + * Locking rules: + * get_parent is called with child->d_inode->i_sem down + * get_name is not (which is possibly inconsistent) + */ + +struct export_operations { + struct dentry *(*decode_fh)(struct super_block *sb, __u32 *fh, int fh_len, int fh_type, + int (*acceptable)(void *context, struct dentry *de), + void *context); + int (*encode_fh)(struct dentry *de, __u32 *fh, int *max_len, + int connectable); + + /* the following are only called from the filesystem itself */ + int (*get_name)(struct dentry *parent, char *name, + struct dentry *child); + struct dentry * (*get_parent)(struct dentry *child); + struct dentry * (*get_dentry)(struct super_block *sb, void *inump); + + /* This is set by the exporting module to a standard helper */ + struct dentry * (*find_exported_dentry)( + struct super_block *sb, void *obj, void *parent, + int (*acceptable)(void *context, struct dentry *de), + void *context); + + +}; + +extern struct dentry * +find_exported_dentry(struct super_block *sb, void *obj, void *parent, + int (*acceptable)(void *context, struct dentry *de), + void *context); + +struct file_system_type { + const char *name; + int fs_flags; + struct super_block *(*get_sb) (struct file_system_type *, int, + const char *, void *); + void (*kill_sb) (struct super_block *); + struct module *owner; + struct file_system_type * next; + struct list_head fs_supers; +}; + +struct super_block *get_sb_bdev(struct file_system_type *fs_type, + int flags, const char *dev_name, void *data, + int (*fill_super)(struct super_block *, void *, int)); +struct super_block *get_sb_single(struct file_system_type *fs_type, + int flags, void *data, + int (*fill_super)(struct super_block *, void *, int)); +struct super_block *get_sb_nodev(struct file_system_type *fs_type, + int flags, void *data, + int (*fill_super)(struct super_block *, void *, int)); +void generic_shutdown_super(struct super_block *sb); +void kill_block_super(struct super_block *sb); +void kill_anon_super(struct super_block *sb); +void kill_litter_super(struct super_block *sb); +void deactivate_super(struct super_block *sb); +int set_anon_super(struct super_block *s, void *data); +struct super_block *sget(struct file_system_type *type, + int (*test)(struct super_block *,void *), + int (*set)(struct super_block *,void *), + void *data); +struct super_block *get_sb_pseudo(struct file_system_type *, char *, + struct super_operations *ops, unsigned long); +int __put_super(struct super_block *sb); +int __put_super_and_need_restart(struct super_block *sb); +void unnamed_dev_init(void); + +/* Alas, no aliases.

A sync request clears this bit, and + * when we find it set with no buffers locked, we know the sync is + * complete. + * + * Buffers for the md device that arrive via make_request are attached + * to the appropriate stripe in one of two lists linked on b_reqnext. + * One list (bh_read) for read requests, one (bh_write) for write. + * There should never be more than one buffer on the two lists + * together, but we are not guaranteed of that so we allow for more. + * + * If a buffer is on the read list when the associated cache buffer is + * Uptodate, the data is copied into the read buffer and it's b_end_io + * routine is called.

Other threads may do this only if they first check + * that the Uptodate bit is set. Once they have checked that they may + * take buffers off the read queue. + * + * When a buffer on the write list is committed for write it is copied + * into the cache buffer, which is then marked dirty, and moved onto a + * third list, the written list (bh_written). Once both the parity + * block and the cached buffer are successfully written, any buffer on + * a written list can be returned with b_end_io. + * + * The write list and read list both act as fifos.

Endpoint + * numbers range from zero to fifteen. Note that "in" endpoint two + * is a different endpoint (and pipe) from "out" endpoint two. + * The current configuration controls the existence, type, and + * maximum packet size of any given endpoint. + * @dev: Identifies the USB device to perform the request. + * @status: This is read in non-iso completion functions to get the + * status of the particular request. ISO requests only use it + * to tell whether the URB was unlinked; detailed status for + * each frame is in the fields of the iso_frame-desc. + * @transfer_flags: A variety of flags may be used to affect how URB + * submission, unlinking, or operation are handled. Different + * kinds of URB can use different flags. + * @transfer_buffer: This identifies the buffer to (or from) which + * the I/O request will be performed (unless URB_NO_TRANSFER_DMA_MAP + * is set). This buffer must be suitable for DMA; allocate it with + * kmalloc() or equivalent. For transfers to "in" endpoints, contents + * of this buffer will be modified. This buffer is used for the data + * stage of control transfers. + * @transfer_dma: When transfer_flags includes URB_NO_TRANSFER_DMA_MAP, + * the device driver is saying that it provided this DMA address, + * which the host controller driver should use in preference to the + * transfer_buffer. + * @transfer_buffer_length: How big is transfer_buffer. The transfer may + * be broken up into chunks according to the current maximum packet + * size for the endpoint, which is a function of the configuration + * and is encoded in the pipe. When the length is zero, neither + * transfer_buffer nor transfer_dma is used. + * @actual_length: This is read in non-iso completion functions, and + * it tells how many bytes (out of transfer_buffer_length) were + * transferred. It will normally be the same as requested, unless + * either an error was reported or a short read was performed. + * The URB_SHORT_NOT_OK transfer flag may be used to make such + * short reads be reported as errors. + * @setup_packet: Only used for control transfers, this points to eight bytes + * of setup data. Control transfers always start by sending this data + * to the device. Then transfer_buffer is read or written, if needed. + * @setup_dma: For control transfers with URB_NO_SETUP_DMA_MAP set, the + * device driver has provided this DMA address for the setup packet. + * The host controller driver should use this in preference to + * setup_packet. + * @start_frame: Returns the initial frame for isochronous transfers. + * @number_of_packets: Lists the number of ISO transfer buffers. + * @interval: Specifies the polling interval for interrupt or isochronous + * transfers. The units are frames (milliseconds) for for full and low + * speed devices, and microframes (1/8 millisecond) for highspeed ones. + * @error_count: Returns the number of ISO transfers that reported errors. + * @context: For use in completion functions. This normally points to + * request-specific driver context. + * @complete: Completion handler. This URB is passed as the parameter to the + * completion function. The completion function may then do what + * it likes with the URB, including resubmitting or freeing it. + * @iso_frame_desc: Used to provide arrays of ISO transfer buffers and to + * collect the transfer status for each buffer. + * + * This structure identifies USB transfer requests. URBs must be allocated by + * calling usb_alloc_urb() and freed with a call to usb_free_urb(). + * Initialization may be done using various usb_fill_*_urb() functions. URBs + * are submitted using usb_submit_urb(), and pending requests may be canceled + * using usb_unlink_urb() or usb_kill_urb(). + * + * Data Transfer Buffers: + * + * Normally drivers provide I/O buffers allocated with kmalloc() or otherwise + * taken from the general page pool. That is provided by transfer_buffer + * (control requests also use setup_packet), and host controller drivers + * perform a dma mapping (and unmapping) for each buffer transferred. Those + * mapping operations can be expensive on some platforms (perhaps using a dma + * bounce buffer or talking to an IOMMU), + * although they're cheap on commodity x86 and ppc hardware. + * + * Alternatively, drivers may pass the URB_NO_xxx_DMA_MAP transfer flags, + * which tell the host controller driver that no such mapping is needed since + * the device driver is DMA-aware. For example, a device driver might + * allocate a DMA buffer with usb_buffer_alloc() or call usb_buffer_map(). + * When these transfer flags are provided, host controller drivers will + * attempt to use the dma addresses found in the transfer_dma and/or + * setup_dma fields rather than determining a dma address themselves. (Note + * that transfer_buffer and setup_packet must still be set because not all + * host controllers use DMA, nor do virtual root hubs). + * + * Initialization: + * + * All URBs submitted must initialize the dev, pipe, transfer_flags (may be + * zero), and complete fields. + * The URB_ASYNC_UNLINK transfer flag affects later invocations of + * the usb_unlink_urb() routine. Note: Failure to set URB_ASYNC_UNLINK + * with usb_unlink_urb() is deprecated. For synchronous unlinks use + * usb_kill_urb() instead. + * + * All URBs must also initialize + * transfer_buffer and transfer_buffer_length. They may provide the + * URB_SHORT_NOT_OK transfer flag, indicating that short reads are + * to be treated as errors; that flag is invalid for write requests. + * + * Bulk URBs may + * use the URB_ZERO_PACKET transfer flag, indicating that bulk OUT transfers + * should always terminate with a short packet, even if it means adding an + * extra zero length packet. + * + * Control URBs must provide a setup_packet. The setup_packet and + * transfer_buffer may each be mapped for DMA or not, independently of + * the other. The transfer_flags bits URB_NO_TRANSFER_DMA_MAP and + * URB_NO_SETUP_DMA_MAP indicate which buffers have already been mapped. + * URB_NO_SETUP_DMA_MAP is ignored for non-control URBs. + * + * Interrupt URBs must provide an interval, saying how often (in milliseconds + * or, for highspeed devices, 125 microsecond units) + * to poll for transfers. After the URB has been submitted, the interval + * field reflects how the transfer was actually scheduled. + * The polling interval may be more frequent than requested. + * For example, some controllers have a maximum interval of 32 milliseconds, + * while others support intervals of up to 1024 milliseconds. + * Isochronous URBs also have transfer intervals. (Note that for isochronous + * endpoints, as well as high speed interrupt endpoints, the encoding of + * the transfer interval in the endpoint descriptor is logarithmic. + * Device drivers must convert that value to linear units themselves.) + * + * Isochronous URBs normally use the URB_ISO_ASAP transfer flag, telling + * the host controller to schedule the transfer as soon as bandwidth + * utilization allows, and then set start_frame to reflect the actual frame + * selected during submission. Otherwise drivers must specify the start_frame + * and handle the case where the transfer can't begin then. However, drivers + * won't know how bandwidth is currently allocated, and while they can + * find the current frame using usb_get_current_frame_number () they can't + * know the range for that frame number. (Ranges for frame counter values + * are HC-specific, and can go from 256 to 65536 frames from "now".) + * + * Isochronous URBs have a different data transfer model, in part because + * the quality of service is only "best effort". Callers provide specially + * allocated URBs, with number_of_packets worth of iso_frame_desc structures + * at the end. Each such packet is an individual ISO transfer. Isochronous + * URBs are normally queued, submitted by drivers to arrange that + * transfers are at least double buffered, and then explicitly resubmitted + * in completion handlers, so + * that data (such as audio or video) streams at as constant a rate as the + * host controller scheduler can support. + * + * Completion Callbacks: + * + * The completion callback is made in_interrupt(), and one of the first + * things that a completion handler should do is check the status field. + * The status field is provided for all URBs. It is used to report + * unlinked URBs, and status for all non-ISO transfers. It should not + * be examined before the URB is returned to the completion handler. + * + * The context field is normally used to link URBs back to the relevant + * driver or request state. + * + * When the completion callback is invoked for non-isochronous URBs, the + * actual_length field tells how many bytes were transferred. This field + * is updated even when the URB terminated with an error or was unlinked. + * + * ISO transfer status is reported in the status and actual_length fields + * of the iso_frame_desc array, and the number of errors is reported in + * error_count.
