    //!     This is a common state command for AVC encoder modes. For encoder, it
    //!     represents both the forward QM matrices as well as the decoding QM
    //!     matrices.This is a Frame-level state. Only Scaling Lists specified by an
    //!     application are being sent to the hardware. The driver is responsible
    //!     for determining the final set of scaling lists to be used for decoding
    //!     the current slice, based on the AVC Spec Table 7-2 (Fall-Back Rules A
    //!     and B).In MFX AVC PAK mode, PAK needs both forward Q scaling lists and
    //!     IQ scaling lists. The IQ scaling lists are sent as in MFD in raster scan
    //!     order. But the Forward Q scaling lists are sent in column-wise raster
    //!     order (column-by-column) to simplify the H/W. Driver will perform all
    //!     the scan order conversion for both ForwardQ and IQ.

    //! \brief MFX_SURFACE_STATE
    //! \details
    //!     This command is common for all encoding/decoding modes, to specify the
    //!     uncompressed YUV picture (i.e. destination surface) or intermediate
    //!     streamout in/out surface (e.g. coefficient/residual) (field, frame or
    //!     interleaved frame) format for reading and writing:  Uncompressed,
    //!     original input picture to be encoded
    //!      Reconstructed non-filtered/filtered display picturec(becoming reference
    //!     pictures as well for subsequent temporal inter-prediction)
    //!      Residual in SVC
    //!      Reconstructed Intra pixel in SVC
    //!      CoeffPred in SVC
    //!       Since there is only one media surface state being active during the
    //!     entire encoding/decoding process, all the uncompressed/reconstructed
    //!     pictures are defined to have the same surface state. For each media
    //!     object call (decoding or encoding), multiple SVC surfaces can be active
    //!     concurrently,  to distinguish among them, a surfaceID is added to
    //!     specify for each type of surface.   The primary difference among picture
    //!     surface states is their individual programmed base addresses, which are
    //!     provided  by other state commands and not included in this command. MFX
    //!     engine is making the association of surface states and corresponding
    //!     buffer base addresses.   MFX engine currently supports only one media
    //!     surface type for video and that is the NV12 (Planar YUV420 with
    //!     interleaved U (Cb) and V (Cr). For optimizing memory efficiency based on
    //!     access patterns, only TileY is supported. For JPEG decoder, only IMC1
    //!     and IMC3 are supported. Pitch can be wider than the Picture Width in
    //!     pixels and garbage will be there at the end of each line. The following
    //!     describes all the different formats that are supported and not supported
    //!     in Gen7 MFX :  NV12 - 4:2:0 only; UV interleaved; Full Pitch, U and V
    //!     offset is set to 0 (the only format supported for video codec); vertical
    //!     UV offset is MB aligned; UV xoffsets = 0. JPEG does not support NV12
    //!     format because non-interleave JPEG has performance issue with partial
    //!     write (in interleaved UV format)
    //!      IMC 1 &amp; 3 - Full Pitch, U and V are separate plane; (JPEG only; U
    //!     plane + garbage first in full pitch followed by V plane + garbage in
    //!     full pitch). U and V vertical offsets are block aligned; U and V xoffset
    //!     = 0; there is no gap between Y, U and V planes. IMC1 and IMC3 are
    //!     different by a swap of U and V. This is the only format supported in
    //!     JPEG for all video subsampling types (4:4:4, 4:2:2 and 4:2:0)
    //!      We are not supporting IMC 2 &amp; 4 - Full Pitch, U and V are separate
    //!     plane (JPEG only; U plane first in full pitch followed by V plane in
    //!     full pitch - U and V plane are side-by-side). U and V vertical offsets
    //!     are 16-pixel aligned; V xoffset is half-pitch aligned; U xoffset is 0;
    //!     there is no gap between Y, U and V planes. IMC2 and IMC4 are different
    //!     by a swap of U and V.
    //!      We are not supporting YV12 - half pitch for each U and V plane, and
    //!     separate planes for Y, U and V (U plane first in half pitch followed by
    //!     V plane in half pitch). For YV12, U and V vertical offsets are block
    //!     aligned; U and V xoffset = 0; there is no gap between Y, U and V planes
    //!       Note that the following data structures are not specified through the
    //!     media surface state  1D buffers for row-store and other miscellaneous
    //!     information.
    //!      2D buffers for per-MB data-structures (e.g. DMV biffer, MB info record,
    //!     ILDB Control and Tcoeff/Stocoeff).
    //!       This surface state here is identical to the Surface State for
    //!     deinterlace and sample_8x8 messages described in the Shared Function
    //!     Volume and Sampler Chapter. For non pixel data, such as row stores,
    //!     indirect data (Compressed Slice Data, AVC MV record, Coeff record and
    //!     AVC ILDB record) and streamin/out and output compressed bitstream, a
    //!     linear buffer is employed. For row stores, the H/W is designed to
    //!     guarantee legal memory accesses (read and write). For the remaining
    //!     cases, indirect object base address, indirect object address upper
    //!     bound, object data start address (offset) and object data length are
    //!     used to fully specified their corresponding buffer. This mechanism is
    //!     chosen over the pixel surface type because of their variable record
    //!     sizes. All row store surfaces are linear surface. Their addresses are
    //!     programmed in Pipe_Buf_Base_State or Bsp_Buf_Base_Addr_State
    //!     
    //!     VC1 I picture scaling: Even though VC1 allows I reconstructed picture
    //!     scaling (via RESPIC), as such scaling is only allowed at I picture. All
    //!     subsequent P (and B) pictures must have the same picture dimensions with
    //!     the preceding I picture. Therefore, all reference pictures for P or B
    //!     picture can share the same surface state with the current P and B
    //!     picture. Note : H/W is not processing RESPIC. Application is no longer
    //!     expecting intel decoder pipelineand kernel to perform this function, it
    //!     is going to be done in the video post-processing scaler or display
    //!     controller scale as a separate step and controller.
    //!     
    //!     All video codec surfaces must be NV12 Compliant, except JPEG. U/V
    //!     vertical must be MB aligned for all video codec (further contrained for
    //!     field picture), but JPEG can be block aligned. All video codec and JPEG
    //!     uses Tiled - Y format only, for uncompressed pixel surfaces.
    //!     
    //!     Even for JPEG planar 420 surface, application may provide only 1
    //!     buffers, but there is still only one single surface state for all of
    //!     them. If IMC equal to 1, 2, 3 or 4, U and V have the pitch same as Y.
    //!     And U and V will have different offset, each offset is block aligned.

    //! \details
    //!     This state command provides the memory base addresses for all row
    //!     stores, StreamOut buffer and reconstructed picture output buffers
    //!     required by the MFD or MFC Engine (that are in addition to the row
    //!     stores of the Bit Stream Decoding/Encoding Unit (BSD/BSE) and the
    //!     reference picture buffers). This is a picture level state command and is
    //!     common among all codec standards and for both encoder and decoder
    //!     operating modes. However, some fields may only applicable to a specific
    //!     codec standard. All Pixel Surfaces (original, reference frame and
    //!     reconstructed frame) in the Encoder are programmed with the same surface
    //!     state (NV12 and TileY format), except each has its own frame buffer base
    //!     address. In the tile format, there is no need to provide buffer offset
    //!     for each slice; since from each MB address, the hardware can calculated
    //!     the corresponding memory location within the frame buffer directly.
    //!     
    //!     The MFX_IND_OBJ_BASE_ADDR command sets the memory base address pointers
    //!     for the corresponding Indirect Object Data Start Addresses (Offsets)
    //!     specified in each OBJECT commands. The characteristic of these indirect
    //!     object data is their variable size (per MB or per Slice). Hence, each
    //!     OBJECT command must specify the indirect object data offset from the
    //!     base address to start fetching or writing object data.
    //!     
    //!     While the use of base address is unconditional, the indirection can be
    //!     effectively disabled by setting the base address to zero. For decoder,
    //!     there are:  1 read-only per-slice indirect object in the BSD_OBJECT
    //!     Command, and
    //!      2 read-only per-MB indirect objects in the IT_OBJECT Command.
    //!       For decoder: the Video Command Streamer (VCS) will perform the memory
    //!     access bound check automatically  using the corresponding MFC Indirect
    //!     Object Access Upper Bound specification. If any access is at or beyond
    //!     the upper bound, zero value is returned. The request to memory is still
    //!     being sent, but the corresponding  codec's BSD unit will detect this
    //!     condition and perform the zeroing return. If the Upper Bound is turned
    //!     off, the beyond bound request will return whatever on the bus (invalid
    //!     data). For encoder, there are:  1 read-only per-MB indirect object in
    //!     the PAK_OBJECT Command, and
    //!      1 write-only per-slice indirect object in the PAK Slice_State Command
    //!       For encoder: whenever an out of bound address accessing request is
    //!     generated, VMX will detect such requests and snap the address to the
    //!     corresponding [indirect object base address + indirect data start
    //!     address]. VMX will return all 0s as the data to the requestor.
    //!     NotationDefinitionPhysicalAddress[n:m] Corresponding bits of a physical

    //!     This frame-level state command is used to specify all the buffer base
    //!     addresses needed for the operation of the AVC Bit Stream Processing
    //!     Units (for decoder, it is BSD Unit; for encoder, it is BSE Unit) For
    //!     both encoder and decoder, currently it is assumed that all codec
    //!     standards can share the same BSP_BUF_BASE_STATE. The simplicity of this
    //!     command is the result of moving all the direct MV related processing
    //!     into the ENC Subsystem. Since all implicit weight calculations and
    //!     directMV calculations are done in ENC and all picture buffer management
    //!     are done in the Host, there is no need to provide POC (POC List -
    //!     FieldOrderCntList, CurrPic POC - CurrFieldOrderCnt) information to PAK.
    //!     For decoder, all the direct mode information are sent in a separate
    //!     slice-level command (AVC_DIRECTMODE_STATE command). In addition, in
    //!     Encoder, the row stores for CABAC encoding and MB Parameters
    //!     Construction (MPC) are combined into one single row store. The row
    //!     stores specified in this command do not combine with those specified in
    //!     the MFC_PIPE_BUF_ADDR_STATE command for hardware simplification reason.

    //!     This is a slice level command and can be issued multiple times within a
    //!     picture that is comprised of multiple slices.  The same command is used
    //!     for AVC encoder (PAK mode) and decoder (VLD mode); it is not need in
    //!     decoder IT mode.   The inline data of this command is interpreted
    //!     differently for encoder as for decoder.  For decoder, it is interpreted
    //!     as RefIdx List L0/L1 as in AVC spec., and it matches with the AVC
    //!     API data structure for decoder in VLD mode : RefPicList[2][32] (L0:L1,
    //!     0:31 RefPic).  But for encoder, it is interpreted as a Reference Index
    //!     Mapping Table for L0 and L1 reference pictures.  For packing the bits at
    //!     the output of PAK, the syntax elements must follow the definition of
    //!     RefIdxL0/L1 list according to the AVC spec.  However, the decoder
    //!     pipeline was designed to use a variation of that standard definition, as
    //!     such a conversion (mapping) is needed to support the hardware design.
    //!     The Reference lists are needed in processing both P and B slice in AVC
    //!     codec. For P-MB, only L0 list is used; for B-MB both L0 and L1 lists are
    //!     needed.  For a B-MB that is coded in L1-only Prediction, only L1 list is
    //!     used.

    //!     L0/L1[ ] is a 7-bit picture index.  This picture index is the same as
    //!     that of RefFrameList[ ] content.  This picture index, however, is not
    //!     defined the same as the frame store ID (0 to 16, 5-bits) we have
    //!     implemented in H/W.  Hence, driver is required to manage a table to
    //!     convert between picture index and intel frame store ID.   As such,
    //!     the final RefPicList L0/L1[ ] that the driver passes onto the H/W is not
    //!     the same as that defined.

    //!     This is a Slice level command used only for AVC Short Slice
    //!     Bitstream Format VLD mode.When decoding a slice, H/W needs to know the
    //!     last MB of the slice has reached in order to start decoding the next
    //!     slice. It also needs to know if a slice is terminated but the last MB
    //!     has not reached, error conealment should be invoked to generate those
    //!     missing MBs. For AVC Short Format, the only way to know the last
    //!     MB position of the current slice, H/W needs to snoop into the next
    //!     slice's start MB address (a linear address encoded in the Slice Header).
    //!     Since each BSD Object command can have only one indirect bitstream
    //!     buffer address, this command is added to help H/W to snoop into the next
    //!     slice's slice header and retrieve its Start MB Address. This command
    //!     will take the next slice's bitstream buffer address as input (exactly
    //!     the same way as a BSD Object command), and parse only the
    //!     first_mb_in_slice syntax element. The result will stored inside the H/W,
    //!     and will be used to decode the current slice specified in the BSD Object
    //!     command.Only the very first few bytes (max 5 bytes for a max 4K picture)
    //!     of the Slice Header will be decoded, the rest of the bitstream are don't
    //!     care. This is because the first_mb_in_slice is encoded in Exponential
    //!     Golomb, and will take 33 bits to represent the max 256 x 256 = 64K-1
    //!     value. The indirect data of MFD_AVC_SLICEADDR is a valid BSD object and
    //!     is decoded as in BSD OBJECT command.The next Slice Start MB Address is
    //!     also exposed to the MMIO interface.The Slice Start MB Address
    //!     (first_mb_in_slice) is a linear MB address count; but it is translated
    //!     into the corresponding 2D MB X and Y raster position, and are stored
    //!     internally as NextSliceMbY and NextSliceMbX.

    //!     bitstream. Internally, MFX hardware will keep track of the very last two
    //!     bytes' (the very last byte can be a partial byte) values of the previous
    //!     insertion. It is required that the next Insertion Object Command or the
    //!     next PAK Object Command to perform the start code emulation sequence
    //!     check and prevention 0x03 byte insertion with this end condition of the
    //!     previous insertion. Hardware will keep track of an output bitstream
    //!     buffer current byte position and the associated next bit insertion
    //!     position index. Data to be inserted can be a valid H.264 NAL units or a
    //!     partial NAL unit. Certain NAL unit has a minimum byte size requirement.
    //!     As such the hardware will optionally (enabled by STATE Command)
    //!     determines the number of CABAC_ZERO_WORD to be inserted to the end of
    //!     the current NAL, based on the minimum byte size of a NAL and the actual
    //!     bin count of the encoded Slice. Since prior to the CABAC_ZERO_WORD
    //!     insertion, the RBSP or EBSP is already byte-aligned, so each
    //!     CABAC_ZERO_WORD insertion is actually a 3-byte sequence 0x00 00 03. The
    //!     inline data may have already been processed for start code emulation
    //!     byte insertion, except the possibility of the last 2 bytes plus the very
    //!     last partial byte (if any). Hence, when hardware performing the
    //!     concatenation of multiple consecutive insertion commands, or
    //!     concatenation of an insertion command and a PAK object command, it must
    //!     check and perform the necessary start code emulation byte insert at the
    //!     junction.The inline data is required to be byte aligned on the left
    //!     (first transmitted bit order) and may or may not be byte aligned on the
    //!     right (last transmitted bits).  The command will specify the bit offset
    //!     of the last valid DW.Each insertion state command defines a chunk of
    //!     bits (compressed data) to be inserted at a specific location of the
    //!     output compressed bitstream in the output buffer.Depend on CABAC or
    //!     CAVLC encoding mode (from Slice State), PAK Object Command is always
    //!     ended in byte aligned output bitstream except for CABAC header insertion
    //!     which is bit aligned. In the aligned cases, PAK will perform 0 filling

    //!     Different from AVC and VC1, MFD_MPEG2_BSD_OBJECT command is pipelinable.
    //!     This is for performance purpose as in MPEG2 a slice is defined as a
    //!     group of MBs of any size that must be within a macroblock row.Slice
    //!     header parameters are passed in as inline data and the bitstream data
    //!     for the slice is passed in as indirect data. Of the inline data,
    //!     slice_horizontal_position and slice_vertical_position determines the
    //!     location within the destination picture of the first macroblock in the
    //!     slice. The content in this command is identical to that in the
    //!     MEDIA_OBJECT command in VLD mode described in the Media Chapter.

    //!     are read or derived from bitstream syntax elements above (inclusive)
    //!     picture header layer. These parameters are static for a picture and when
    //!     slice structure is present, these parameters are not changed from slice
    //!     to slice of the same picture. Hence, this command is only issued at the
    //!     beginning of processing a new picture and prior to the VC1_*_OBJECT
    //!     command. The values set for these state variables are retained
    //!     internally across slices.Only the parameters needed by hardware (BSD
    //!     unit) to decode bit sequence for the macroblocks in a picture layer or a
    //!     slice layer are presented in this command. Other parameters such as the
    //!     ones used for inverse transform or motion compensation are provided in
    //!     MFX_VC1_PRED_PIPE_STATE command.This Long interface format is intel
    //!     proprietary interface. Driver will need to perform addition operations
    //!     to generate all the fields in this command.

    //!     The MFD_VC1_BSD_OBJECT command is the only primitive command for the VC1
    //!     Decoding Pipeline. The macroblock data portion of the bitstream is
    //!     loaded as indirect data object.Before issuing a MFD_VC1_BSD_OBJECT
    //!     command, all VC1 states of the MFD Engine need to be valid. Therefore
    //!     the commands used to set these states need to have been issued prior to
    //!     the issue of a MFD_VC1_BSD_OBJECT command.VC1 deblock filter kernel
    //!     cross the slice boundary if in the last MB row of a slice, so need to
    //!     know the last MB row of a slice to disable the edge mask. There is why
    //!     VC1 BSD hardware need to know the end of MB address for the current
    //!     slice. As such no more phantom slice is needed for VC1, as long as the
    //!     driver will program both start MB address in the current slice and the
    //!     start MB address of the next slice. As a result, we can also support
    //!     multiple picture state commands in between slices.
