- *
- * 20000710 Nils Faerber
- * Initial Version 0.01
- * 20000728 Nils Faerber
- * 0.02 Fix for SMI_EN->TCO_EN bit, some cleanups
- * 20011214 Matt Domsch <Matt_Domsch@dell.com>
- * 0.03 Added nowayout module option to override CONFIG_WATCHDOG_NOWAYOUT
- * Didn't add timeout option as i810_margin already exists.
- * 20020224 Joel Becker, Wim Van Sebroeck
- * 0.04 Support for 82801CA(M) chipset, timer margin needs to be > 3,
- * add support for WDIOC_SETTIMEOUT and WDIOC_GETTIMEOUT.
- * 20020412 Rob Radez <rob@osinvestor.com>, Wim Van Sebroeck
- * 0.05 Fix possible timer_alive race, add expect close support,
- * clean up ioctls (WDIOC_GETSTATUS, WDIOC_GETBOOTSTATUS and
- * WDIOC_SETOPTIONS), made i810tco_getdevice __init,
- * removed boot_status, removed tco_timer_read,
- * added support for 82801DB and 82801E chipset,
- * added support for 82801EB and 8280ER chipset,
- * general cleanup.
- * 20030921 Wim Van Sebroeck <wim@iguana.be>
- * 0.06 change i810_margin to heartbeat, use module_param,
- * added notify system support, renamed module to i8xx_tco.
- * 20050128 Wim Van Sebroeck <wim@iguana.be>
- * 0.07 Added support for the ICH4-M, ICH6, ICH6R, ICH6-M, ICH6W and ICH6RW
- * chipsets. Also added support for the "undocumented" ICH7 chipset.
- * 20050807 Wim Van Sebroeck <wim@iguana.be>
- * 0.08 Make sure that the watchdog is only "armed" when started.
- * (Kernel Bug 4251)
- * 20060416 Wim Van Sebroeck <wim@iguana.be>
- * 0.09 Remove support for the ICH6, ICH6R, ICH6-M, ICH6W and ICH6RW and
- * ICH7 chipsets. (See Kernel Bug 6031 - other code will support these
- * chipsets)

+ * This function provides low-level access to the IEEE1394 transaction

+ * this function. The fw_send_request() function is primarily
+ * provided as a flexible, one-stop entry point for languages bindings
+ * and protocol bindings.
+ *
+ * FIXME: Document this function further, in particular the possible
+ * values for rcode in the callback. In short, we map ACK_COMPLETE to
+ * RCODE_COMPLETE, internal errors set errno and set rcode to
+ * RCODE_SEND_ERROR (which is out of range for standard ieee1394
+ * rcodes). All other rcodes are forwarded unchanged. For all
+ * errors, payload is NULL, length is 0.
+ *
+ * Can not expect the callback to be called before the function
+ * returns, though this does happen in some cases (ACK_COMPLETE and
+ * errors).
+ *
+ * The payload is only used for write requests and must not be freed
+ * until the callback has been called.
+ *
+ * @param card the card from which to send the request
+ * @param tcode the tcode for this transaction. Do not use
+ * TCODE_LOCK_REQUEST directly, insted use TCODE_LOCK_MASK_SWAP
+ * etc. to specify tcode and ext_tcode.
+ * @param node_id the destination node ID (bus ID and PHY ID concatenated)
+ * @param generation the generation for which node_id is valid
+ * @param speed the speed to use for sending the request
+ * @param offset the 48 bit offset on the destination node
+ * @param payload the data payload for the request subaction
+ * @param length the length in bytes of the data to read
+ * @param callback function to be called when the transaction is completed
+ * @param callback_data pointer to arbitrary data, which will be

-config UNIX98_PTYS
- bool "Unix98 PTY support"
- ---help---
- A pseudo terminal (PTY) is a software device consisting of two
- halves: a master and a slave. The slave device behaves identical to
- a physical terminal; the master device is used by a process to
- read data from and write data to the slave, thereby emulating a
- terminal. Typical programs for the master side are telnet servers
- and xterms.
-
- Linux has traditionally used the BSD-like names /dev/ptyxx for
- masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
- has a number of problems. The GNU C library glibc 2.1 and later,
- however, supports the Unix98 naming standard: in order to acquire a
- pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
- terminal is then made available to the process and the pseudo
- terminal slave can be accessed as /dev/pts/<number>. What was
- traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
-
- The entries in /dev/pts/ are created on the fly by a virtual
- file system; therefore, if you say Y here you should say Y to
- "/dev/pts file system for Unix98 PTYs" as well.
-
- If you want to say Y here, you need to have the C library glibc 2.1
- or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
- Read the instructions in <file:Documentation/Changes> pertaining to
- pseudo terminals. It's safe to say N.

- The maximum number of Unix98 PTYs that can be used at any one time.
- The default is 256, and should be enough for desktop systems. Server
- machines which support incoming telnet/rlogin/ssh connections and/or
- serve several X terminals may want to increase this: every incoming
- connection and every xterm uses up one PTY.
-
- When not in use, each additional set of 256 PTYs occupy
- approximately 8 KB of kernel memory on 32-bit architectures.
