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.

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 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 *(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.

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 retrieved. The user should check the result list - to determine the specific status of the transaction. - -VIII.

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 appropriately: - - EFAULT Invalid user space pointer was passed - ENXIO Invalid IOP number - ETIMEDOUT Timeout waiting for reply message - ENOMEM Kernel memory allocation error - -IX. Uploading Software - - SYNOPSIS - - ioctl(fd, I2OSWUL, struct i2o_sw_xfer *sw); - - struct i2o_sw_xfer - { - u32 iop; /* IOP unit number */ - u8 flags; /* UploadFlags */ - u8 sw_type; /* Software type */ - u32 sw_id; /* Software ID */ - void *buf; /* Pointer to software buffer */ - u32 *swlen; /* Length of software buffer */ - u32 *maxfrag; /* Number of fragments */ - u32 *curfrag; /* Current fragment number */ - }; - - DESCRIPTION - - This function uploads a software fragment from the IOP identified - 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 - is returned and errno is set appropriately: - - EFAULT Invalid user space pointer was passed - ENXIO Invalid IOP number - ETIMEDOUT Timeout waiting for reply message - ENOMEM Kernel memory allocation error - -X.

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 appropriately: - - 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 appropriately: - - ETIMEDOUT Timeout waiting for reply message - ENXIO Invalid IOP number - -XI.

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 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 *(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. - -============================================================================= -Revision History -============================================================================= - -Rev 0.1 - 04/01/99 -- Initial revision - -Rev 0.2 - 04/06/99 -- Changed return values to match UNIX ioctl() standard.
