-The \fBdlim_addr_lo\fR and \fBdlim_addr_hi\fR fields specify the address range
-the device's \fBDMA\fR engine can access. The \fBdlim_addr_lo\fR field
-describes the lower 32-bit boundary of the device's \fBDMA\fR engine, the
-\fBdlim_addr_hi\fR describes the inclusive upper 32-bit boundary. The system
-allocates \fBDMA\fR resources in a way that the address for programming the
-device's \fBDMA\fR engine (see \fBddi_dma_cookie\fR(9S) or
-\fBddi_dma_htoc\fR(9F)) is within this range. For example, if your device can
-access the whole 32-bit address range, you may use  [\fB0\fR,\fB0xFFFFFFFF\fR].
-If your device has just a 16-bit address  register but will access the top of
-the 32-bit address range, then  [\fB0xFFFF0000\fR,\fB0xFFFFFFFF\fR] is the
-right limit.
-.sp
-.LP
-The \fBdlim_cntr_max\fR field describes an inclusive upper bound for the
-device's \fBDMA\fR engine address register. This handles a fairly common case
-where a portion of the address register is only a latch rather than a full
-register. For example, the upper 8 bits of a 32-bit address register can be a
-latch. This splits the address register into a portion that acts as a true
-address register (24 bits) for a 16 Mbyte segment and a latch (8 bits) to hold
-a segment number. To describe these limits, specify  \fB0xFFFFFF\fR in the
-\fBdlim_cntr_max\fR structure.
-.sp
-.LP
-The \fBdlim_burstsizes\fR field describes the possible burst sizes the device's
-\fBDMA\fR engine can accept. At the time of a \fBDMA\fR resource request, this
-element defines the possible \fBDMA\fR burst cycle sizes that the requester's
-\fBDMA\fR engine can handle. The format of the data is binary encoding of burst
-sizes assumed to be powers of two. That is, if a \fBDMA\fR engine is capable of
-doing 1-, 2-, 4-, and 16-byte transfers, the encoding ix 0x17. If the device is
-an SBus device and can take advantage of a 64-bit SBus, the lower 16 bits are
-used to specify the burst size for 32-bit transfers and the upper 16 bits are
-used to specify the burst size for 64-bit transfers. As the resource request is
-handled by the system, the \fBburstsizes\fR value can be modified. Prior to
-enabling \fBDMA\fR for the specific device, the driver that owns the \fBDMA\fR
-engine should check (using \fBddi_dma_burstsizes\fR(9F)) what the allowed
-\fBburstsizes\fR have become and program the \fBDMA\fR engine appropriately.
-.sp
-.LP
-The \fBdlim_minxfer\fR field describes the minimum effective \fBDMA\fR transfer
-size (in units of bytes). It must be a power of two. This value specifies the
-minimum effective granularity of the \fBDMA\fR engine. It is distinct from
-\fBdlim_burstsizes\fR in that it describes the minimum amount of access a
-\fBDMA\fR transfer will effect. \fBdlim_burstsizes\fR describes in what
-electrical fashion the \fBDMA\fR engine might perform its accesses, while
-\fBdlim_minxfer\fR describes the minimum amount of memory that can be touched
-by the \fBDMA\fR transfer. As a resource request is handled by the system, the
-\fBdlim_minxfer\fR value can be modified contingent upon the presence (and use)
-of \fBI/O \fRcaches and \fBDMA\fR write buffers in between the \fBDMA\fR engine
-and the object that \fBDMA\fR is being performed on. After \fBDMA\fR resources
-have been allocated, the resultant minimum transfer value can be gotten using
-\fBddi_dma_devalign\fR(9F).
-.sp
-.LP
-The field \fBdlim_dmaspeed\fR is the expected average data rate for the
-\fBDMA\fR engine (in units of kilobytes per second). Note that this should not
-be the maximum, or peak, burst data rate, but a reasonable guess as to the
-average throughput. This field is entirely optional and can be left as zero.
-Its intended use is to provide some hints about how much of the \fBDMA\fR
-resource this device might need.

-The \fBdlim_granular\fR field describes the granularity of the device's

-broken into multiples of this value. If there is no scatter/gather capability,
-then the size of each \fBDMA\fR transfer will be a multiple of this value. If
-there is scatter/gather capability, then a single segment cannot be smaller

-The  \fBdlim_sgllen\fR field specifies the maximum number of entries in the

-The \fBdlim_reqsize\fR field describes the maximum number of bytes that the

-.sp
-.LP
-A \fBddi_dma_req\fR structure describes a request for \fBDMA\fR resources. A
-driver can use it to describe forms of allocations and ways to allocate
-\fBDMA\fR resources for a \fBDMA\fR request.

-DDI_DMA_RDWR          /* Both read and write */

-DDI_DMA_SBUS_64BIT    /* Use 64 bit capability on SBus */
-.fi
-.in -2
-
-.sp
-.LP
-\fBDDI_DMA_WRITE\fR, \fBDDI_DMA_READ\fR, and \fBDDI_DMA_RDWR\fR describe the
-intended direction of the \fBDMA \fRtransfer. Some implementations might
-explicitly disallow \fBDDI_DMA_RDWR\fR.
-.sp
-.LP
-\fBDDI_DMA_REDZONE\fR asks the system to establish a protected  \fBred zone\fR
-after the object. The \fBDMA\fR resource allocation functions do not guarantee
-the success of this request, as some implementations might not have the
-hardware ability to support it.
-.sp
-.LP
-\fBDDI_DMA_PARTIAL\fR lets the system know that the caller can accept partial
-mapping. That is, if the size of the object exceeds the resources available,
-the system allocates only a portion of the object and returns status indicating
-this partial allocation. At a later point, the caller can use
-\fBddi_dma_curwin\fR(9F) and \fBddi_dma_movwin\fR(9F) to change the valid
-portion of the object that has resources allocated.
-.sp
-.LP
-\fBDDI_DMA_CONSISTENT\fR gives a hint to the system that the object should be
-mapped for  \fBbyte consistent\fR access. Normal data transfers usually use a
-\fBstreaming\fR mode of operation. They start at a specific point, transfer a
-fairly large amount of data sequentially, and then stop, usually on an aligned
-boundary. Control mode data transfers for memory-resident device control blocks
-(for example, Ethernet message descriptors) do not access memory in such a
-sequential fashion. Instead, they tend to modify a few words or bytes, move
-around and maybe modify a few more.
-.sp
-.LP
-Many machine implementations make this non-sequential memory access difficult
-to control in a generic and seamless fashion. Therefore, explicit
-synchronization steps using \fBddi_dma_sync\fR(9F) or \fBddi_dma_free\fR(9F)
-are required to make the view of a memory object shared between a \fBCPU \fRand
-a \fBDMA\fR device consistent. However, proper use of the
-\fBDDI_DMA_CONSISTENT\fR flag can create a condition in which a system will
-pick resources in a way that makes these synchronization steps are as efficient
-as possible.
-.sp
-.LP
-\fBDDI_DMA_SBUS_64BIT\fR tells the system that the device can perform 64-bit
-transfers on a 64-bit SBus. If the SBus does not support 64-bit data transfers,
-data will be transferred in 32-bit mode.
-.sp
-.LP
-The callback function specified by the member \fBdmar_fp\fR indicates how a
-caller to one of the \fBDMA\fR resource allocation functions wants to deal with
-the possibility of resources not being available. (See
-\fBddi_dma_setup\fR(9F).) If \fBdmar_fp\fR is set to \fBDDI_DMA_DONTWAIT\fR,
-then the caller does not care if the allocation fails, and can deal with an
-allocation failure appropriately. Setting \fBdmar_fp\fR to \fBDDI_DMA_SLEEP\fR
-indicates the caller wants to have the allocation routines wait for resources
-to become available. If any other value is set, and a \fBDMA\fR resource
-allocation fails, this value is assumed to be a function to call later, when
-resources become available. When the specified function is called, it is passed
-the value set in the structure member \fBdmar_arg\fR. The specified callback
-function \fBmust\fR return either:
-.sp
-.ne 2
-.na
-\fB\fB0\fR\fR
-.ad
-.RS 5n
-Indicating that it attempted to allocate a \fBDMA\fR resource but failed to do
-so, again, in which case the callback function will be put back on a list to be
-called again later.
-.RE
-
-.sp
-.ne 2
-.na
-\fB\fB1\fR\fR
-.ad
-.RS 5n
-Indicating either success at allocating \fBDMA\fR resources or that it no
-longer wants to retry.
-.RE
-
-.sp
-.LP
-The callback function is called in interrupt context. Therefore, only system
-functions and contexts that are accessible from interrupt context are
-available. The callback function must take whatever steps necessary to protect
-its critical resources, data structures, and queues.
-.sp
-.LP
-It is possible that a call to \fBddi_dma_free\fR(9F), which frees \fBDMA\fR
-resources, might cause a callback function to be called and, unless some care
-is taken, an undesired recursion can occur. This can cause an undesired
-recursive \fBmutex_enter\fR(9F), which makes the system panic.
-.SS "dmar_object Structure"
-.sp
-.LP
-The \fBdmar_object\fR member of the \fBddi_dma_req\fR structure is itself a
-complex and extensible structure:
-.sp
-.in +2
-.nf
-uint_t            dmao_size;     /* size, in bytes, of the object */
-ddi_dma_atyp_t    dmao_type;     /* type of object */
-ddi_dma_aobj_t    dmao_obj;      /* the object described */
-.fi
-.in -2
-
-.sp
-.LP
-The  \fBdmao_size\fR element is the size, in bytes, of the object resources
-allocated for \fBDMA\fR.
-.sp
-.LP
-The \fBdmao_type\fR element selects the kind of object described by
-\fBdmao_obj\fR. It can be set to \fBDMA_OTYP_VADDR\fR, indicating virtual
-addresses.
-.sp
-.LP
-The last element, \fBdmao_obj\fR, consists of the virtual address type:
-.sp
-.in +2
