-.El
-.Pp
-The most common application of
-.Nm
-is for running
-.Xr X 7 Pq Pa ports/x11/xorg-docs
-on the Intel i81x controllers.
-.Sh IOCTLS
-The following
-.Xr ioctl 2
-operations can be performed on
-.Pa /dev/agpgart ,
-which are defined in
-.In sys/agpio.h :
-.Bl -tag -width indent
-.It Dv AGPIOC_INFO
-Returns state of the
-.Nm
-system.
-The result is a pointer to the following structure:
-.Bd -literal
-typedef struct _agp_info {
- agp_version version; /* version of the driver */
- uint32_t bridge_id; /* bridge vendor/device */
- uint32_t agp_mode; /* mode info of bridge */
- off_t aper_base; /* base of aperture */
- size_t aper_size; /* size of aperture */
- size_t pg_total; /* max pages (swap + system) */
- size_t pg_system; /* max pages (system) */
- size_t pg_used; /* current pages used */
-} agp_info;
-.Ed
-.It Dv AGPIOC_ACQUIRE
-Acquire control of the AGP chipset for use by this client.
-Returns
-.Er EBUSY
-if the AGP chipset is already acquired by another client.
-.It Dv AGPIOC_RELEASE
-Release control of the AGP chipset.
-This does not unbind or free any allocated memory, which is the
-responsibility of the client to handle if necessary.
-.It Dv AGPIOC_SETUP
-Enable the AGP hardware with the relevant mode.
-This
-.Xr ioctl 2
-takes the following structure:
-.Bd -literal
-typedef struct _agp_setup {
- uint32_t agp_mode; /* mode info of bridge */
-} agp_setup;
-.Ed
-.Pp
-The mode bits are defined in
-.In sys/agpio.h .
-.It Dv AGPIOC_ALLOCATE
-Allocate physical memory suitable for mapping into the AGP aperture.
-This
-.Xr ioctl 2
-takes the following structure:
-.Bd -literal
-typedef struct _agp_allocate {
- int key; /* tag of allocation */
- size_t pg_count; /* number of pages */
- uint32_t type; /* 0 == normal, other devspec */
- uint32_t physical; /* device specific (some devices
- * need a phys address of the
- * actual page behind the gatt
- * table) */
-} agp_allocate;
-.Ed
-.Pp
-Returns a handle to the allocated memory.
-.It Dv AGPIOC_DEALLOCATE
-Free the previously allocated memory associated with the handle passed.
-.It Dv AGPIOC_BIND
-Bind the allocated memory at given offset with the AGP aperture.
-Returns
-.Er EINVAL
-if the memory is already bound or the offset is not at AGP page boundary.
-This
-.Xr ioctl 2
-takes the following structure:
-.Bd -literal
-typedef struct _agp_bind {
- int key; /* tag of allocation */
- off_t pg_start; /* starting page to populate */
-} agp_bind;
-.Ed
-.Pp
-The tag of allocation is the handle returned by
-.Dv AGPIOC_ALLOCATE .
-.It Dv AGPIOC_UNBIND
-Unbind memory from the AGP aperture.
-Returns
-.Er EINVAL
-if the memory is not bound.
-This
-.Xr ioctl 2
-takes the following structure:
-.Bd -literal
-typedef struct _agp_unbind {
- int key; /* tag of allocation */
- uint32_t priority; /* priority for paging out */
-} agp_unbind;
-.Ed
-.El
-.Sh FILES
