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!

+config I2O
+	tristate "I2O support"
+	depends on PCI
+	---help---
+	  The Intelligent Input/Output (I2O) architecture allows hardware
+	  drivers to be split into two parts: an operating system specific
+	  module called the OSM and an hardware specific module called the
+	  HDM. The OSM can talk to a whole range of HDM's, and ideally the
+	  HDM's are not OS dependent. This allows for the same HDM driver to
+	  be used under different operating systems if the relevant OSM is in
+	  place. In order for this to work, you need to have an I2O interface
+	  adapter card in your computer. This card contains a special I/O
+	  processor (IOP), thus allowing high speeds since the CPU does not
+	  have to deal with I/O.
+
+	  If you say Y here, you will get a choice of interface adapter
+	  drivers and OSM's with the following questions.
+
+	  To compile this support as a module, choose M here: the
+	  modules will be called i2o_core.
+
+	  If unsure, say N.
+
+config I2O_CONFIG
+	tristate "I2O Configuration support"
+	depends on PCI && I2O
+	help
+	  Say Y for support of the configuration interface for the I2O adapters.
+	  If you have a RAID controller from Adaptec and you want to use the
+	  raidutils to manage your RAID array, you have to say Y here.
+
+	  To compile this support as a module, choose M here: the
+	  module will be called i2o_config.
+
+config I2O_BLOCK
+	tristate "I2O Block OSM"
+	depends on I2O
+	help
+	  Include support for the I2O Block OSM. The Block OSM presents disk
+	  and other structured block devices to the operating system. If you
+	  are using an RAID controller, you could access the array only by
+	  the Block OSM driver. But it is possible to access the single disks
+	  by the SCSI OSM driver, for example to monitor the disks.
+
+	  To compile this support as a module, choose M here: the
+	  module will be called i2o_block.
+
+config I2O_SCSI
+	tristate "I2O SCSI OSM"
+	depends on I2O && SCSI
+	help
+	  Allows direct SCSI access to SCSI devices on a SCSI or FibreChannel
+	  I2O controller. You can use both the SCSI and Block OSM together if
+	  you wish. To access a RAID array, you must use the Block OSM driver.
+	  But you could use the SCSI OSM driver to monitor the single disks.
+
+	  To compile this support as a module, choose M here: the

+
+config I2O_PROC
+	tristate "I2O /proc support"

+Linux I2O User Space Interface
+rev 0.3 - 04/20/99
+
+=============================================================================
+Originally written by Deepak Saxena(deepak@plexity.net)
+Currently maintained by Deepak Saxena(deepak@plexity.net)
+=============================================================================
+
+I. Introduction
+
+The Linux I2O subsystem provides a set of ioctl() commands that can be
+utilized by user space applications to communicate with IOPs and devices
+on individual IOPs. This document defines the specific ioctl() commands
+that are available to the user and provides examples of their uses.
+
+This document assumes the reader is familiar with or has access to the 
+I2O specification as no I2O message parameters are outlined.  For information 
+on the specification, see http://www.i2osig.org
+
+This document and the I2O user space interface are currently maintained
+by Deepak Saxena.  Please send all comments, errata, and bug fixes to
+deepak@csociety.purdue.edu
+
+II. IOP Access
+
+Access to the I2O subsystem is provided through the device file named 
+/dev/i2o/ctl.  This file is a character file with major number 10 and minor
+number 166.  It can be created through the following command:
+
+   mknod /dev/i2o/ctl c 10 166
+
+III. Determining the IOP Count
+
+   SYNOPSIS 
+
+   ioctl(fd, I2OGETIOPS,  int *count);
+
+   u8 count[MAX_I2O_CONTROLLERS];
+
+   DESCRIPTION
+
+   This function returns the system's active IOP table.  count should
+   point to a buffer containing MAX_I2O_CONTROLLERS entries.  Upon 
+   returning, each entry will contain a non-zero value if the given
+   IOP unit is active, and NULL if it is inactive or non-existent.
+
+   RETURN VALUE.
+
+   Returns 0 if no errors occur, and -1 otherwise.  If an error occurs,
+   errno is set appropriately:
+
+     EFAULT   Invalid user space pointer was passed
+
+IV. Getting Hardware Resource Table
+
+   SYNOPSIS 
+ 
+   ioctl(fd, I2OHRTGET, struct i2o_cmd_hrt *hrt);
+
+      struct i2o_cmd_hrtlct
+      {
+         u32   iop;      /* IOP unit number */
+         void  *resbuf;  /* Buffer for result */
+         u32   *reslen;  /* Buffer length in bytes */
+      };
+
+   DESCRIPTION
+
+   This function returns the Hardware Resource Table of the IOP specified 
+   by hrt->iop in the buffer pointed to by hrt->resbuf. The actual size of 
+   the data is written into *(hrt->reslen).
+
+   RETURNS
+
+   This function returns 0 if no errors occur. If an error occurs, -1 
+   is returned and errno is set appropriately:
+
+      EFAULT      Invalid user space pointer was passed
+      ENXIO       Invalid IOP number
+      ENOBUFS     Buffer not large enough.  If this occurs, the required
+                  buffer length is written into *(hrt->reslen)
+  
+V. Getting Logical Configuration Table
+   
+   SYNOPSIS 
+ 
+   ioctl(fd, I2OLCTGET, struct i2o_cmd_lct *lct);
+
+      struct i2o_cmd_hrtlct
+      {
+         u32   iop;      /* IOP unit number */
+         void  *resbuf;  /* Buffer for result */
+         u32   *reslen;  /* Buffer length in bytes */
+      };
+
+   DESCRIPTION
+
+   This function returns the Logical Configuration Table of the IOP specified
+   by lct->iop in the buffer pointed to by lct->resbuf. The actual size of 
+   the data is written into *(lct->reslen).
+
+   RETURNS
+
+   This function returns 0 if no errors occur. If an error occurs, -1 
+   is returned and errno is set appropriately:
+
+      EFAULT      Invalid user space pointer was passed
+      ENXIO       Invalid IOP number
+      ENOBUFS     Buffer not large enough.  If this occurs, the required
+                  buffer length is written into *(lct->reslen)
+
+VI. Settting Parameters
+   
+   SYNOPSIS 
+ 
+   ioctl(fd, I2OPARMSET, struct i2o_parm_setget *ops);
+
+      struct i2o_cmd_psetget
+      {
+         u32   iop;      /* IOP unit number */
+         u32   tid;      /* Target device TID */
+         void  *opbuf;   /* Operation List buffer */
+         u32   oplen;    /* Operation List buffer length in bytes */
+         void  *resbuf;  /* Result List buffer */
+         u32   *reslen;  /* Result List buffer length in bytes */
+      };
+
+   DESCRIPTION
+
+   This function posts a UtilParamsSet message to the device identified
+   by ops->iop and ops->tid.  The operation list for the message is 
+   sent through the ops->opbuf buffer, and the result list is written
+   into the buffer pointed to by ops->resbuf.  The number of bytes 
+   written is placed into *(ops->reslen). 
+
+   RETURNS
+
+   The return value is the size in bytes of the data written into
+   ops->resbuf if no errors occur.  If an error occurs, -1 is returned 
+   and errno is set appropriatly:
+
+      EFAULT      Invalid user space pointer was passed
+      ENXIO       Invalid IOP number
+      ENOBUFS     Buffer not large enough.  If this occurs, the required
+                  buffer length is written into *(ops->reslen)
+      ETIMEDOUT   Timeout waiting for reply message
+      ENOMEM      Kernel memory allocation error
+
+   A return value of 0 does not mean that the value was actually
+   changed properly on the IOP.  The user should check the result
+   list to determine the specific status of the transaction.
+
+VII. Getting Parameters
+   
+   SYNOPSIS 
+ 
+   ioctl(fd, I2OPARMGET, struct i2o_parm_setget *ops);
+
+      struct i2o_parm_setget
+      {
+         u32   iop;      /* IOP unit number */
+         u32   tid;      /* Target device TID */
+         void  *opbuf;   /* Operation List buffer */
+         u32   oplen;    /* Operation List buffer length in bytes */
+         void  *resbuf;  /* Result List buffer */
+         u32   *reslen;  /* Result List buffer length in bytes */
+      };
+
+   DESCRIPTION
+
+   This function posts a UtilParamsGet message to the device identified
+   by ops->iop and ops->tid.  The operation list for the message is 
+   sent through the ops->opbuf buffer, and the result list is written
+   into the buffer pointed to by ops->resbuf.  The actual size of data
+   written is placed into *(ops->reslen).
+
+   RETURNS
+
+      EFAULT      Invalid user space pointer was passed
+      ENXIO       Invalid IOP number
+      ENOBUFS     Buffer not large enough.  If this occurs, the required
+                  buffer length is written into *(ops->reslen)
+      ETIMEDOUT   Timeout waiting for reply message
+      ENOMEM      Kernel memory allocation error
+
+   A return value of 0 does not mean that the value was actually
+   properly retreived.  The user should check the result list 
+   to determine the specific status of the transaction.
+
+VIII. Downloading Software
+   
+   SYNOPSIS 
+

+         u32   *swlen;    /* Length of software buffer */        
+         u32   *maxfrag;  /* Number of fragments */
+         u32   *curfrag;  /* Current fragment number */
+      };
+
+   DESCRIPTION
+
+   This function downloads a software fragment pointed by sw->buf
+   to the iop identified by sw->iop. The DownloadFlags, SwID, SwType
+   and SwSize fields of the ExecSwDownload message are filled in with
+   the values of sw->flags, sw->sw_id, sw->sw_type and *(sw->swlen).
+
+   The fragments _must_ be sent in order and be 8K in size. The last
+   fragment _may_ be shorter, however. The kernel will compute its
+   size based on information in the sw->swlen field.
+
+   Please note that SW transfers can take a long time.
+
+   RETURNS
+
+   This function returns 0 no errors occur. If an error occurs, -1 
+   is returned and errno is set appropriatly:
+

+   by sw->iop, sw->sw_type, sw->sw_id and optionally sw->swlen fields.
+   The UploadFlags, SwID, SwType and SwSize fields of the ExecSwUpload
+   message are filled in with the values of sw->flags, sw->sw_id,
+   sw->sw_type and *(sw->swlen).
+
+   The fragments _must_ be requested in order and be 8K in size. The
+   user is responsible for allocating memory pointed by sw->buf. The
+   last fragment _may_ be shorter.
+
+   Please note that SW transfers can take a long time.
+
+   RETURNS
+
+   This function returns 0 if no errors occur.  If an error occurs, -1

+      };
+
+   DESCRIPTION
+
+   This function removes software from the IOP identified by sw->iop.
+   The RemoveFlags, SwID, SwType and SwSize fields of the ExecSwRemove message 
+   are filled in with the values of sw->flags, sw->sw_id, sw->sw_type and 
+   *(sw->swlen). Give zero in *(sw->len) if the value is unknown. IOP uses 
+   *(sw->swlen) value to verify correct identication of the module to remove. 
+   The actual size of the module is written into *(sw->swlen).
+
+   RETURNS
+
+   This function returns 0 if no errors occur.  If an error occurs, -1
+   is returned and errno is set appropriatly:
+
+      EFAULT      Invalid user space pointer was passed
+      ENXIO       Invalid IOP number
+      ETIMEDOUT   Timeout waiting for reply message
+      ENOMEM      Kernel memory allocation error
+
+X. Validating Configuration
+
+   SYNOPSIS
+
+   ioctl(fd, I2OVALIDATE, int *iop);
+	u32 iop;
+
+   DESCRIPTION
+
+   This function posts an ExecConfigValidate message to the controller
+   identified by iop. This message indicates that the current
+   configuration is accepted. The iop changes the status of suspect drivers 
+   to valid and may delete old drivers from its store.
+
+   RETURNS
+
+   This function returns 0 if no erro occur.  If an error occurs, -1 is
+   returned and errno is set appropriatly:
+
+      ETIMEDOUT   Timeout waiting for reply message

+
+XI. Configuration Dialog
+   
+   SYNOPSIS 
+ 
+   ioctl(fd, I2OHTML, struct i2o_html *htquery);
+      struct i2o_html
+      {
+         u32   iop;      /* IOP unit number */
+         u32   tid;      /* Target device ID */
+         u32   page;     /* HTML page */
+         void  *resbuf;  /* Buffer for reply HTML page */
+         u32   *reslen;  /* Length in bytes of reply buffer */
+         void  *qbuf;    /* Pointer to HTTP query string */
+         u32   qlen;     /* Length in bytes of query string buffer */        
+      };
+
+   DESCRIPTION
+
+   This function posts an UtilConfigDialog message to the device identified
+   by htquery->iop and htquery->tid.  The requested HTML page number is 
+   provided by the htquery->page field, and the resultant data is stored 
+   in the buffer pointed to by htquery->resbuf.  If there is an HTTP query 
+   string that is to be sent to the device, it should be sent in the buffer
+   pointed to by htquery->qbuf.  If there is no query string, this field
+   should be set to NULL. The actual size of the reply received is written
+   into *(htquery->reslen).
+  
+   RETURNS
+
+   This function returns 0 if no error occur. If an error occurs, -1
+   is returned and errno is set appropriatly:
+
+      EFAULT      Invalid user space pointer was passed
+      ENXIO       Invalid IOP number
+      ENOBUFS     Buffer not large enough.  If this occurs, the required
+                  buffer length is written into *(ops->reslen)
+      ETIMEDOUT   Timeout waiting for reply message
+      ENOMEM      Kernel memory allocation error
+
+XII. Events
+
+    In the process of determining this.  Current idea is to have use
+    the select() interface to allow user apps to periodically poll
+    the /dev/i2o/ctl device for events.  When select() notifies the user
+    that an event is available, the user would call read() to retrieve
+    a list of all the events that are pending for the specific device.
