- Stop this driver on ControllerHandle.\r
-\r
- The Stop() function is designed to be invoked from the EFI boot service DisconnectController().\r
- As a result, much of the error checking on the parameters to Stop() has been moved\r
- into this common boot service. It is legal to call Stop() from other locations,\r
- but the following calling restrictions must be followed or the system behavior will not be deterministic.\r
- 1. ControllerHandle must be a valid EFI_HANDLE that was used on a previous call to this\r
- same driver's Start() function.\r
- 2. The first NumberOfChildren handles of ChildHandleBuffer must all be a valid\r
- EFI_HANDLE. In addition, all of these handles must have been created in this driver's\r
- Start() function, and the Start() function must have called OpenProtocol() on\r
- ControllerHandle with an Attribute of EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER.\r
-\r
- @param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.\r
- @param[in] ControllerHandle A handle to the device being stopped. The handle must\r
- support a bus specific I/O protocol for the driver\r
- to use to stop the device.\r
- @param[in] NumberOfChildren The number of child device handles in ChildHandleBuffer.\r
- @param[in] ChildHandleBuffer An array of child handles to be freed. May be NULL\r
- if NumberOfChildren is 0.\r
-\r
- @retval EFI_SUCCESS The device was stopped.\r

- 2. The first NumberOfChildren handles of ChildHandleBuffer must all be a valid\r
- EFI_HANDLE. In addition, all of these handles must have been created in this driver's\r
- Start() function, and the Start() function must have called OpenProtocol() on\r
- ControllerHandle with an Attribute of EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER.\r

-\r
- 1. Examine the Programming Interface byte of the Class Code fields in PCI IDE\r
- controller's Configuration Space to determine the operating mode.\r
-\r
- 2. a) In 'Compatibility' mode, use fixed addresses shown in the Table 1 below.\r

- | Channel | Registers | Registers |\r
- |___________|_______________|_______________|\r
- | Primary | 1F0h - 1F7h | 3F6h - 3F7h |\r

- |___________|_______________|_______________|\r
-\r
- Table 1. Compatibility resource mappings\r

- 1. Examine the Programming Interface byte of the Class Code fields in PCI IDE\r
- controller's Configuration Space to determine the operating mode.\r
-\r

- UNDI ISR\r
- Op-Code: PXENV_UNDI_ISR (0014h)\r
- Input: Far pointer to a PXENV_UNDI_ISR_T parameter structure that has been initialized by the caller.\r
- Output: PXENV_EXIT_SUCCESS or PXENV_EXIT_FAILURE must be returned in AX. The status field in\r
- the parameter structure must be set to one of the values represented by the PXENV_STATUS_xxx\r
- constants.\r
- Description: This API function will be called at different levels of processing the interrupt. The FuncFlag field in\r
- the parameter block indicates the operation to be performed for the call. This field is filled with the\r
- status of that operation on return.\r
- Note: Interrupt Service Routine Operation:\r
- In this design the UNDI does not hook the interrupt for the Network Interface. Instead, the\r
- application or the protocol driver hooks the interrupt and calls UNDI with the PXENV_UNDI_ISR\r
- API call for interrupt verification (PXENV_UNDI_ISR_IN_START) and processing\r
- (PXENV_UNDI_ISR_IN_PROCESS and PXENV_UNDI_ISR_GET_NEXT).\r
- When the Network Interface HW generates an interrupt the protocol driver interrupt service\r
- routine (ISR) gets control and takes care of the interrupt processing at the PIC level. The ISR then\r
- calls the UNDI using the PXENV_UNDI_ISR API with the value PXENV_UNDI_ISR_IN_START for\r
- the FuncFlag parameter. At this time UNDI must disable the interrupts at the Network Interface\r
- level and read any status values required to further process the interrupt. UNDI must return as\r
- quickly as possible with one of the two values, PXENV_UNDI_ISR_OUT_OURS or\r
- PXENV_UNDI_ISR_OUT_NOT_OURS, for the parameter FuncFlag depending on whether the\r
- interrupt was generated by this particular Network Interface or not.\r
- If the value returned in FuncFlag is PXENV_UNDI_ISR_OUT_NOT_OURS, then the interrupt was\r
- not generated by our NIC, and interrupt processing is complete.\r
- If the value returned in FuncFlag is PXENV_UNDI_ISR_OUT_OURS, the protocol driver must start\r
- a handler thread and send an end-of-interrupt (EOI) command to the PIC. Interrupt processing is\r
- now complete.\r
- The protocol driver strategy routine will call UNDI using this same API with FuncFlag equal to\r
- PXENV_UNDI_ISR_IN_PROCESS. At this time UNDI must find the cause of this interrupt and\r
- return the status in the FuncFlag. It first checks if there is a frame received and if so it returns the\r
- first buffer pointer of that frame in the parameter block.\r
- The protocol driver calls UNDI repeatedly with the FuncFlag equal to\r
- PXENV_UNDI_ISR_IN_GET_NEXT to get all the buffers in a frame and also all the received\r
- frames in the queue. On this call, UNDI must remember the previous buffer given to the protoco,l\r
- remove it from the receive queue and recycle it. In case of a multi-buffered frame, if the previous\r
- buffer is not the last buffer in the frame it must return the next buffer in the frame in the parameter\r
- block. Otherwise it must return the first buffer in the next frame.\r
- If there is no received frame pending to be processed, UNDI processes the transmit completes and\r
- if there is no other interrupt status to be processed, UNDI re-enables the interrupt at the\r
- NETWORK INTERFACE level and returns PXENV_UNDI_ISR_OUT_DONE in the FuncFlag.\r
- IMPORTANT: It is possible for the protocol driver to be interrupted again while in the\r
- strategy routine when the UNDI re-enables interrupts.\r

- Input: Far pointer to a PXENV_UNDI_ISR_T parameter structure that has been initialized by the caller.\r
- Output: PXENV_EXIT_SUCCESS or PXENV_EXIT_FAILURE must be returned in AX. The status field in\r
- the parameter structure must be set to one of the values represented by the PXENV_STATUS_xxx\r
- constants.\r
- Description: This API function will be called at different levels of processing the interrupt. The FuncFlag field in\r
- the parameter block indicates the operation to be performed for the call. This field is filled with the\r
- status of that operation on return.\r
- Note: Interrupt Service Routine Operation:\r
- In this design the UNDI does not hook the interrupt for the Network Interface. Instead, the\r
- application or the protocol driver hooks the interrupt and calls UNDI with the PXENV_UNDI_ISR\r
- API call for interrupt verification (PXENV_UNDI_ISR_IN_START) and processing\r
- (PXENV_UNDI_ISR_IN_PROCESS and PXENV_UNDI_ISR_GET_NEXT).\r
- When the Network Interface HW generates an interrupt the protocol driver interrupt service\r
- routine (ISR) gets control and takes care of the interrupt processing at the PIC level. The ISR then\r
- calls the UNDI using the PXENV_UNDI_ISR API with the value PXENV_UNDI_ISR_IN_START for\r
- the FuncFlag parameter. At this time UNDI must disable the interrupts at the Network Interface\r
- level and read any status values required to further process the interrupt. UNDI must return as\r
- quickly as possible with one of the two values, PXENV_UNDI_ISR_OUT_OURS or\r
- PXENV_UNDI_ISR_OUT_NOT_OURS, for the parameter FuncFlag depending on whether the\r
- interrupt was generated by this particular Network Interface or not.\r
- If the value returned in FuncFlag is PXENV_UNDI_ISR_OUT_NOT_OURS, then the interrupt was\r
- not generated by our NIC, and interrupt processing is complete.\r
- If the value returned in FuncFlag is PXENV_UNDI_ISR_OUT_OURS, the protocol driver must start\r
- a handler thread and send an end-of-interrupt (EOI) command to the PIC. Interrupt processing is\r
- now complete.\r
- The protocol driver strategy routine will call UNDI using this same API with FuncFlag equal to\r
- PXENV_UNDI_ISR_IN_PROCESS. At this time UNDI must find the cause of this interrupt and\r
- return the status in the FuncFlag. It first checks if there is a frame received and if so it returns the\r
- first buffer pointer of that frame in the parameter block.\r
- The protocol driver calls UNDI repeatedly with the FuncFlag equal to\r
- PXENV_UNDI_ISR_IN_GET_NEXT to get all the buffers in a frame and also all the received\r
- frames in the queue. On this call, UNDI must remember the previous buffer given to the protoco,l\r
- remove it from the receive queue and recycle it. In case of a multi-buffered frame, if the previous\r
- buffer is not the last buffer in the frame it must return the next buffer in the frame in the parameter\r
- block. Otherwise it must return the first buffer in the next frame.\r
- If there is no received frame pending to be processed, UNDI processes the transmit completes and\r
- if there is no other interrupt status to be processed, UNDI re-enables the interrupt at the\r
- NETWORK INTERFACE level and returns PXENV_UNDI_ISR_OUT_DONE in the FuncFlag.\r
- IMPORTANT: It is possible for the protocol driver to be interrupted again while in the\r
- strategy routine when the UNDI re-enables interrupts.\r

- Maps a memory region for DMA.\r

- This function returns the device-specific addresses required to access system memory.\r
- This function is used to map system memory for ISA DMA operations. All ISA DMA\r
- operations must be performed through their mapped addresses, and such mappings must\r
- be freed with EFI_ISA_IO_PROTOCOL.Unmap() after the DMA operation is completed.\r
-\r
- If the DMA operation is a single read or write data transfer through an ISA bus\r
- master, then EfiIsaIoOperationBusMasterRead or EfiIsaIoOperationBusMasterWrite\r
- is used and the range is unmapped to complete the operation. If the DMA operation\r
- is a single read or write data transfer through an ISA slave controller, then\r
- EfiIsaIoOperationSlaveRead or EfiIsaIoOperationSlaveWrite is used and the range\r
- is unmapped to complete the operation.\r
-\r
- If performing a DMA read operation, all the data must be present in system memory before the Map() is performed. Similarly,\r
- if performing a DMA write operation, the data must not be accessed in system\r
- memory until EFI_ISA_IO_PROTOCOL.Unmap() is performed. Bus master operations that\r
- require both read and write access or require multiple host device interactions\r
- within the same mapped region must use EfiIsaIoOperationBusMasterCommonBuffer.\r
- However, only memory allocated via the EFI_ISA_IO_PROTOCOL.AllocateBuffer() interface\r
- is guaranteed to be able to be mapped for this operation type. In all mapping\r
- requests the NumberOfBytes returned may be less than originally requested. It is\r
- the caller's responsibility to make additional requests to complete the entire\r

- For EFI boot option, BDS separate them as six types:\r
- 1. Network - The boot option points to the SimpleNetworkProtocol device.\r
- Bds will try to automatically create this type boot option when enumerate.\r
- 2. Shell - The boot option points to internal flash shell.\r
- Bds will try to automatically create this type boot option when enumerate.\r
- 3. Removable BlockIo - The boot option only points to the removable media\r
- device, like USB flash disk, DVD, Floppy etc.\r
- These device should contain a *removable* blockIo\r
- protocol in their device handle.\r
- Bds will try to automatically create this type boot option\r
- when enumerate.\r
- 4. Fixed BlockIo - The boot option only points to a Fixed blockIo device,\r
- like HardDisk.\r
- These device should contain a *fixed* blockIo\r
- protocol in their device handle.\r
- BDS will skip fixed blockIo devices, and NOT\r
- automatically create boot option for them. But BDS\r
- will help to delete those fixed blockIo boot option,\r
- whose description rule conflict with other auto-created\r
- boot options.\r
- 5. Non-BlockIo Simplefile - The boot option points to a device whose handle\r
- has SimpleFileSystem Protocol, but has no blockio\r
- protocol. These devices do not offer blockIo\r
- protocol, but BDS still can get the\r
- \EFI\BOOT\boot{machinename}.EFI by SimpleFileSystem\r
- Protocol.\r
- 6. File - The boot option points to a file. These boot options are usually\r
- created by user manually or OS loader. BDS will not delete or modify\r
- these boot options.\r
-\r
- This function will enumerate all possible boot device in the system, and\r
- automatically create boot options for Network, Shell, Removable BlockIo,\r
- and Non-BlockIo Simplefile devices.\r

-HISTORY of the LZMA SDK\r
------------------------\r
-\r
-18.05 2018-04-30\r
--------------------------\r
-- The speed for LZMA/LZMA2 compressing was increased \r
- by 8% for fastest/fast compression levels and \r
- by 3% for normal/maximum compression levels.\r
-- Previous versions of 7-Zip could work incorrectly in "Large memory pages" mode in\r
- Windows 10 because of some BUG with "Large Pages" in Windows 10. \r
- Now 7-Zip doesn't use "Large Pages" on Windows 10 up to revision 1709 (16299).\r
-- The BUG was fixed in Lzma2Enc.c\r
- Lzma2Enc_Encode2() function worked incorretly,\r
- if (inStream == NULL) and the number of block threads is more than 1.\r
-\r
-\r
-18.03 beta 2018-03-04\r
--------------------------\r
-- Asm\x86\LzmaDecOpt.asm: new optimized LZMA decoder written in asm \r
- for x64 with about 30% higher speed than main version of LZMA decoder written in C.\r
-- The speed for single-thread LZMA/LZMA2 decoder written in C was increased by 3%.\r
-- 7-Zip now can use multi-threading for 7z/LZMA2 decoding,\r
- if there are multiple independent data chunks in LZMA2 stream.\r
-- 7-Zip now can use multi-threading for xz decoding,\r
- if there are multiple blocks in xz stream.\r
-\r
-\r
-18.01 2019-01-28\r
--------------------------\r
-- The BUG in 17.01 - 18.00 beta was fixed:\r
- XzDec.c : random block unpacking and XzUnpacker_IsBlockFinished()\r
- didn't work correctly for xz archives without checksum (CRC).\r
-\r
-\r
-18.00 beta 2019-01-10\r
--------------------------\r
-- The BUG in xz encoder was fixed:\r
- There was memory leak of 16 KB for each file compressed with \r
- xz compression method, if additional filter was used.\r
-\r
-\r
-17.01 beta 2017-08-28\r
--------------------------\r
-- Minor speed optimization for LZMA2 (xz and 7z) multi-threading compression.\r
- 7-Zip now uses additional memory buffers for multi-block LZMA2 compression.\r
- CPU utilization was slightly improved.\r
-- 7-zip now creates multi-block xz archives by default. Block size can be \r
- specified with -ms[Size]{m|g} switch.\r
-- xz decoder now can unpack random block from multi-block xz archives.\r
-- 7-Zip command line: @listfile now doesn't work after -- switch.\r
- Use -i@listfile before -- switch instead.\r
-- The BUGs were fixed:\r
- 7-Zip 17.00 beta crashed for commands that write anti-item to 7z archive.\r
-\r
-\r
-17.00 beta 2017-04-29\r
--------------------------\r
-- NewHandler.h / NewHandler.cpp: \r
- now it redefines operator new() only for old MSVC compilers (_MSC_VER < 1900).\r

-------------------------- \r
-- The BUG in C version of 7z decoder was fixed:\r
- 7zDec.c : SzDecodeLzma2()\r
- 7z decoder could mistakenly report about decoding error for some 7z archives\r
- that use LZMA2 compression method.\r
- The probability to get that mistaken decoding error report was about \r
- one error per 16384 solid blocks for solid blocks larger than 16 KB (compressed size). \r
-- The BUG (in 9.26-15.11) in C version of 7z decoder was fixed:\r
- 7zArcIn.c : SzReadHeader2()\r

-- The BUG in LZMA / LZMA2 encoding code was fixed.\r
- The BUG in LzFind.c::MatchFinder_ReadBlock() function.\r
- If input data size is larger than (4 GiB - dictionary_size),\r
- the following code worked incorrectly:\r
- - LZMA : LzmaEnc_MemEncode(), LzmaEncode() : LZMA encoding functions \r
- for compressing from memory to memory. \r
- That BUG is not related to LZMA encoder version that works via streams.\r
- - LZMA2 : multi-threaded version of LZMA2 encoder worked incorrectly, if \r
- default value of chunk size (CLzma2EncProps::blockSize) is changed \r

-\r
-9.36 beta 2014-12-26\r
-------------------------- \r
-- The BUG in command line version was fixed:\r
- 7-Zip created temporary archive in current folder during update archive\r
- operation, if -w{Path} switch was not specified. \r
- The fixed 7-Zip creates temporary archive in folder that contains updated archive.\r
-- The BUG in 9.33-9.35 was fixed:\r
- 7-Zip silently ignored file reading errors during 7z or gz archive creation,\r
- and the created archive contained only part of file that was read before error.\r
- The fixed 7-Zip stops archive creation and it reports about error.\r

-LZMA SDK 18.05\r
---------------\r
-\r
-LZMA SDK provides the documentation, samples, header files,\r
-libraries, and tools you need to develop applications that \r
-use 7z / LZMA / LZMA2 / XZ compression.\r
-\r
-LZMA is an improved version of famous LZ77 compression algorithm. \r
-It was improved in way of maximum increasing of compression ratio,\r
-keeping high decompression speed and low memory requirements for \r
-decompressing.\r
-\r
-LZMA2 is a LZMA based compression method. LZMA2 provides better \r
-multithreading support for compression than LZMA and some other improvements.\r
-\r
-7z is a file format for data compression and file archiving.\r
-7z is a main file format for 7-Zip compression program (www.7-zip.org).\r
-7z format supports different compression methods: LZMA, LZMA2 and others.\r
-7z also supports AES-256 based encryption.\r
-\r
-XZ is a file format for data compression that uses LZMA2 compression.\r
-XZ format provides additional features: SHA/CRC check, filters for \r
-improved compression ratio, splitting to blocks and streams,\r
-\r

-LZMA features\r
--------------\r
- - Variable dictionary size (up to 1 GB)\r
- - Estimated compressing speed: about 2 MB/s on 2 GHz CPU\r
- - Estimated decompressing speed: \r
- - 20-30 MB/s on modern 2 GHz cpu\r
- - 1-2 MB/s on 200 MHz simple RISC cpu: (ARM, MIPS, PowerPC)\r
- - Small memory requirements for decompressing (16 KB + DictionarySize)\r
- - Small code size for decompressing: 5-8 KB\r
-\r
-LZMA decoder uses only integer operations and can be \r
-implemented in any modern 32-bit CPU (or on 16-bit CPU with some conditions).\r
-\r
-Some critical operations that affect the speed of LZMA decompression:\r
- 1) 32*16 bit integer multiply\r
- 2) Mispredicted branches (penalty mostly depends from pipeline length)\r
- 3) 32-bit shift and arithmetic operations\r
-\r
-The speed of LZMA decompressing mostly depends from CPU speed.\r
-Memory speed has no big meaning. But if your CPU has small data cache, \r
-overall weight of memory speed will slightly increase.\r
-\r
-\r
-How To Use\r
-----------\r
-\r
-Using LZMA encoder/decoder executable\r
---------------------------------------\r
-\r
-Usage: LZMA <e|d> inputFile outputFile [<switches>...]\r
-\r
- e: encode file\r
-\r
- d: decode file\r
-\r
- b: Benchmark. There are two tests: compressing and decompressing \r
- with LZMA method. Benchmark shows rating in MIPS (million \r
- instructions per second). Rating value is calculated from \r
- measured speed and it is normalized with Intel's Core 2 results.\r
- Also Benchmark checks possible hardware errors (RAM \r
- errors in most cases). Benchmark uses these settings:\r
- (-a1, -d21, -fb32, -mfbt4). You can change only -d parameter. \r
- Also you can change the number of iterations. Example for 30 iterations:\r
- LZMA b 30\r
- Default number of iterations is 10.\r
-\r
-<Switches>\r
- \r
-\r
- -a{N}: set compression mode 0 = fast, 1 = normal\r
- default: 1 (normal)\r
-\r
- d{N}: Sets Dictionary size - [0, 30], default: 23 (8MB)\r
- The maximum value for dictionary size is 1 GB = 2^30 bytes.\r
- Dictionary size is calculated as DictionarySize = 2^N bytes. \r
- For decompressing file compressed by LZMA method with dictionary \r
- size D = 2^N you need about D bytes of memory (RAM).\r
-\r
- -fb{N}: set number of fast bytes - [5, 273], default: 128\r
- Usually big number gives a little bit better compression ratio \r
- and slower compression process.\r
-\r
- -lc{N}: set number of literal context bits - [0, 8], default: 3\r
- Sometimes lc=4 gives gain for big files.\r
-\r
- -lp{N}: set number of literal pos bits - [0, 4], default: 0\r
- lp switch is intended for periodical data when period is \r
- equal 2^N. For example, for 32-bit (4 bytes) \r
- periodical data you can use lp=2. Often it's better to set lc0, \r
- if you change lp switch.\r
-\r
- -pb{N}: set number of pos bits - [0, 4], default: 2\r
- pb switch is intended for periodical data \r
- when period is equal 2^N.\r
-\r
- -mf{MF_ID}: set Match Finder. Default: bt4. \r
- Algorithms from hc* group doesn't provide good compression \r
- ratio, but they often works pretty fast in combination with \r
- fast mode (-a0).\r
-\r
- Memory requirements depend from dictionary size \r
- (parameter "d" in table below). \r
-\r
- MF_ID Memory Description\r
-\r
- bt2 d * 9.5 + 4MB Binary Tree with 2 bytes hashing.\r
- bt3 d * 11.5 + 4MB Binary Tree with 3 bytes hashing.\r
- bt4 d * 11.5 + 4MB Binary Tree with 4 bytes hashing.\r
- hc4 d * 7.5 + 4MB Hash Chain with 4 bytes hashing.\r
-\r
- -eos: write End Of Stream marker. By default LZMA doesn't write \r
- eos marker, since LZMA decoder knows uncompressed size \r
- stored in .lzma file header.\r
-\r
- -si: Read data from stdin (it will write End Of Stream marker).\r
- -so: Write data to stdout\r
-\r
-\r
-Examples:\r
-\r
-1) LZMA e file.bin file.lzma -d16 -lc0 \r
-\r
-compresses file.bin to file.lzma with 64 KB dictionary (2^16=64K) \r
-and 0 literal context bits. -lc0 allows to reduce memory requirements \r
-for decompression.\r
-\r
-\r
-2) LZMA e file.bin file.lzma -lc0 -lp2\r
-\r
-compresses file.bin to file.lzma with settings suitable \r
-for 32-bit periodical data (for example, ARM or MIPS code).\r
-\r
-3) LZMA d file.lzma file.bin\r
-\r
-decompresses file.lzma to file.bin.\r
-\r
-\r
-Compression ratio hints\r
------------------------\r
-\r
-Recommendations\r
----------------\r
-\r
-To increase the compression ratio for LZMA compressing it's desirable \r
-to have aligned data (if it's possible) and also it's desirable to locate\r
-data in such order, where code is grouped in one place and data is \r
-grouped in other place (it's better than such mixing: code, data, code,\r
-data, ...).\r
-\r
-\r
-Filters\r
--------\r
-You can increase the compression ratio for some data types, using\r
-special filters before compressing. For example, it's possible to \r
-increase the compression ratio on 5-10% for code for those CPU ISAs: \r
-x86, IA-64, ARM, ARM-Thumb, PowerPC, SPARC.\r
-\r
-You can find C source code of such filters in C/Bra*.* files\r
-\r
-You can check the compression ratio gain of these filters with such \r
-7-Zip commands (example for ARM code):\r
-No filter:\r
- 7z a a1.7z a.bin -m0=lzma\r
-\r
-With filter for little-endian ARM code:\r
- 7z a a2.7z a.bin -m0=arm -m1=lzma \r
-\r
-It works in such manner:\r
-Compressing = Filter_encoding + LZMA_encoding\r
-Decompressing = LZMA_decoding + Filter_decoding\r
-\r
-Compressing and decompressing speed of such filters is very high,\r
-so it will not increase decompressing time too much.\r
-Moreover, it reduces decompression time for LZMA_decoding, \r
-since compression ratio with filtering is higher.\r
-\r
-These filters convert CALL (calling procedure) instructions \r
-from relative offsets to absolute addresses, so such data becomes more \r
-compressible.\r
-\r
-For some ISAs (for example, for MIPS) it's impossible to get gain from such filter.\r

-/** @file\r
- Section Extraction Protocol implementation.\r
-\r
- Stream database is implemented as a linked list of section streams,\r
- where each stream contains a linked list of children, which may be leaves or\r
- encapsulations.\r
-\r
- Children that are encapsulations generate new stream entries\r
- when they are created. Streams can also be created by calls to\r
- SEP->OpenSectionStream().\r
-\r
- The database is only created far enough to return the requested data from\r
- any given stream, or to determine that the requested data is not found.\r
-\r
- If a GUIDed encapsulation is encountered, there are three possiblilites.\r
-\r
- 1) A support protocol is found, in which the stream is simply processed with\r
- the support protocol.\r
-\r
- 2) A support protocol is not found, but the data is available to be read\r
- without processing. In this case, the database is built up through the\r
- recursions to return the data, and a RPN event is set that will enable\r
- the stream in question to be refreshed if and when the required section\r
- extraction protocol is published.This insures the AuthenticationStatus\r
- does not become stale in the cache.\r
-\r
- 3) A support protocol is not found, and the data is not available to be read\r
- without it. This results in EFI_PROTOCOL_ERROR.\r
