NAME

       fbio - frame buffer control operations

DESCRIPTION

       The frame buffers provided with this release support the same general interface that is defined by <sys/fbio.h>. Each responds to an FBIOG-
       TYPE ioctl(2) request which returns information in a fbtype structure.

       Each device has an FBTYPE which is used by higher-level software to determine how to perform graphics functions. Each  device  is  used	by
       opening	it,  doing an FBIOGTYPE ioctl() to see which frame buffer type is present, and thereby selecting the appropriate device-management
       routines.

       FBIOGINFO returns information specific to the GS accelerator.

       FBIOSVIDEO and FBIOGVIDEO are general-purpose ioctl() requests for controlling possible video features  of  frame  buffers.  These  ioctl()
       requests  either  set  or  return  the  value  of  a  flags  integer. At this point, only the FBVIDEO_ON option is available, controlled by
       FBIOSVIDEO. FBIOGVIDEO returns the current video state.

       The FBIOSATTR and FBIOGATTR ioctl() requests allow access to special features of newer frame buffers. They use  the   fbsattr  and  fbgattr
       structures.

       Some  color  frame  buffers  support  the  FBIOPUTCMAP and FBIOGETCMAP ioctl() requests, which provide access to the colormap. They use the
       fbcmap structure.

       Also, some framebuffers with multiple colormaps will either encode the colormap identifier in the high-order bits of the "index"  field	in
       the fbcmap structure, or use the FBIOPUTCMAPI and FBIOGETCMAPI ioctl() requests.

       FBIOVERTICAL is used to wait for the start of the next vertical retrace period.

       FBIOVRTOFFSET  Returns  the offset to a read-only vertical retrace page for those framebuffers that support it.	This vertical retrace page
       may be mapped into user space with mmap(2). The first word of the vertical retrace page (type unsigned int) is a  counter  that	is  incre-
       mented every time there is a vertical retrace.  The user process can use this counter in a variety of ways.

       FBIOMONINFO returns a mon_info structure which contains information about the monitor attached to the framebuffer, if available.

       FBIOSCURSOR,  FBIOGCURSOR,  FBIOSCURPOS	and FBIOGCURPOS are used to control the hardware cursor for those framebuffers that have this fea-
       ture. FBIOGCURMAX returns the maximum sized cursor supported by the framebuffer.  Attempts to create a cursor larger than this will fail.

       Finally FBIOSDEVINFO and FBIOGDEVINFO are used to transfer variable-length, device-specific information into and out of framebuffers.

BUGS

       The FBIOSATTR and FBIOGATTR ioctl() requests are only supported by frame buffers which emulate older frame buffer types. If a frame  buffer
       emulates another frame buffer, FBIOGTYPE returns the emulated type. To get the real type, use FBIOGATTR.

       The  FBIOGCURPOS  ioctl	was incorrectly defined in previous operating systems, and older code running in binary compatibility mode may get
       incorrect results.

NAME

       hdio - SMD and IPI disk control operations

SYNOPSIS

       #include <sys/hdio.h>

DESCRIPTION

       Note -  The SMC and IPI drivers have been discontinued. dkio(7I) is now the preferred method for retrieving disk information.

       The  SMD  and  IPI  disk  drivers supplied with this release support a set of ioctl(2) requests for diagnostics and bad sector information.
       Basic to these  ioctl() requests are the definitions in <sys/hdio.h>.

IOCTLS

       HDKIOCGTYPE     The argument is a pointer to a hdk_type structure (described below).  This ioctl() gets specific information from the  hard
		       disk.

       HDKIOCSTYPE     The argument is a pointer to a hdk_type structure (described below).  This ioctl() sets specific information about the hard
		       disk.

       /*
	* Used for drive info
	*/
       struct hdk_type {
	ushort_t  hdkt_hsect;	 /* hard sector count (read only) */
	ushort_t  hdkt_promrev;  /* prom revision (read only) */
	uchar_t   hdkt_drtype;	 /* drive type (ctlr specific) */
	uchar_t   hdkt_drstat;	 /* drive status (ctlr specific, ro) */
       };

       HDKIOCGBAD      The argument is a pointer to a hdk_badmap structure (described below).  This ioctl() is used to get the bad sector map from
		       the disk.

       HDKIOCSBAD      The  argument  is a pointer to a hdk_badmap structure (described below).  This ioctl() is used to set the bad sector map on
		       the disk.

       /*
	* Used for bad sector map
	*/
       struct hdk_badmap {
	    caddr_t   hdkb_bufaddr;  /* address of user's map buffer */
       };

       HDKIOCGDIAG     The argument is a pointer to a hdk_diag structure (described below).  This ioctl() gets the most recent command that failed
		       along with the sector and error number from the hard disk.

       /*
	* Used for disk diagnostics
	*/
       struct hdk_diag {
	ushort_t hdkd_errcmd;  /* most recent command in error */
	daddr_t  hdkd_errsect; /* most recent sector in error */
	uchar_t  hdkd_errno;   /* most recent error number */
	uchar_t  hdkd_severe;  /* severity of most recent error */
       };
