For this we will write a custom function `PrintConfigString`: +```cpp +- gST->ConOut->OutputString(gST->ConOut, Result); ++ PrintConfigString(Result); +``` + +In our `PrintConfigString` function we would split the configuration string by the keyword separator `&` and use another `PrintConfigSubString` function to print each `=` pair: +```cpp +VOID PrintConfigString( + IN EFI_STRING ConfigString + ) +{ + UINTN StartIndex=0; + for (UINTN i=0; ConfigString[i] != 0; i++) { + if (ConfigString[i] == L'&') { + ConfigString[i] = 0; <--- we can modify the string as we wouldn't need it after this function + PrintConfigSubString(&ConfigString[StartIndex]); + StartIndex = i+1; + } + } + PrintConfigSubString(&ConfigString[StartIndex]); +} +``` + +Here is how our `PrintConfigSubString` function would look like: +```cpp +VOID PrintConfigSubString( + IN EFI_STRING ConfigString + ) +{ + EFI_STATUS Status; + if (StrStr(ConfigString, L"GUID=")) { + <...> // display the full string and actual guid + } else if (StrStr(ConfigString, L"NAME=")) { + <...> // display the full string and actual name + } else if (StrStr(ConfigString, L"PATH=")) { + <...> + } else if (StrStr(ConfigString, L"VALUE=")) { + <...> // display the full string and actual value + } else if (StrStr(ConfigString, L"OFFSET=") || StrStr(ConfigString, L"WIDTH=")) { + Print(L"%s ", ConfigString); // don't print '\n', so we could see the "OFFSET=<...> WIDTH=<...> VALUE=<...>" on the same string + } else { + Print(L"%s\n", ConfigString); + } +} +``` + +Here you can see, that for each key we would need a special code to print it. +If the string starts with a `GUID=`/`NAME=`/`PATH=` we will parse the data and display actual GUID/Name/DevicePath in a readable standard format. If the string starts with `VALUE=` we would display its data as a hex buffer similar to hexdump. If the string starts with `OFFSET=` or `WIDTH=` we would display data as-is and without any carriage return, so the `OFFSET`/`WIDTH`/`VALUE` data would be placed at the same string. + +## `GUID=` + +Let's start with the `GUID=` string handling. First of all we print a new line `Print(L"\n")` as `GUID=` signifies a start of a new configuration header. Next we pass the string key data to our special `GuidFromCfgString` function that creates `EFI_GUID` value on the heap from the string content: +```cpp +Print(L"\n"); +EFI_GUID* Guid; +Status = GuidFromCfgString(&ConfigString[StrLen(L"GUID=")], StrLen(ConfigString) - StrLen(L"GUID="), &Guid); +if (!EFI_ERROR(Status)) + Print(L"%s (%g)\n", ConfigString, Guid); +else + Print(L"%s\n", ConfigString); +FreePool(Guid); +``` + +The `GuidFromCfgString` function in turn uses `ByteCfgStringToBuffer` helper to get `EFI_GUID` data as an array: +```cpp +EFI_STATUS GuidFromCfgString(CHAR16* CfgString, UINTN Size, EFI_GUID** Guid) +{ + UINTN GuidSize; + ByteCfgStringToBuffer(CfgString, Size, (UINT8**)Guid, &GuidSize); + if (GuidSize != sizeof(EFI_GUID)) + return EFI_NOT_FOUND; + return EFI_SUCCESS; +} +``` + +And here is the `ByteCfgStringToBuffer` function. It receives config string and its length as arguments and returns bytes buffer with its size: +```cpp +VOID ByteCfgStringToBuffer(CHAR16* CfgString, UINTN CfgStringLen, UINT8** Buffer, UINTN* BufferSize) +{ + *BufferSize = (CfgStringLen + 1) / 2; + *Buffer = (UINT8*)AllocateZeroPool(*BufferSize); + UINT8 DigitUint8; + CHAR16 TempStr[2] = {0}; + for (UINTN Index = 0; Index < CfgStringLen; Index++) { + TempStr[0] = CfgString[Index]; + DigitUint8 = (UINT8)StrHexToUint64(TempStr); + if ((Index & 1) == 0) { + (*Buffer)[Index/2] = DigitUint8; + } else { + (*Buffer)[Index/2] = (UINT8)(((*Buffer)[Index/2] << 4) + DigitUint8); + } + } +} +``` + +What does this function do? Let's some part from the output as an example: +``` +GUID=1cc53572800cab4c87ac3b084a6304b1 +``` +In this case `ByteCfgStringToBuffer` function will only receive the string data portion: +``` +1cc53572800cab4c87ac3b084a6304b1 +``` +and construct byte array like this: +```cpp +{0x1c, 0xc5, 0x35, 0x72, 0x80, 0x0c, 0xab, 0x4c, 0x87, 0xac, 0x3b, 0x08, 0x4a, 0x63, 0x04, 0xb1} +``` +Which is the same as: +```cpp +{{0x7235c51c}, {0x0c80}, {0x4cab}, {0x87, 0xac, 0x3b, 0x08, 0x4a, 0x63, 0x04, 0xb1}} +``` +And this is the GUID `gOvmfPlatformConfigGuid` from the [https://github.com/tianocore/edk2/blob/master/OvmfPkg/OvmfPkg.dec](https://github.com/tianocore/edk2/blob/master/OvmfPkg/OvmfPkg.dec): +``` +[Guids] + ... + gOvmfPlatformConfigGuid = {0x7235c51c, 0x0c80, 0x4cab, {0x87, 0xac, 0x3b, 0x08, 0x4a, 0x63, 0x04, 0xb1}} +``` +So you just need to cast the returned buffer to `EFI_GUID` and you can print it as usual with `%g`. As the `EFI_GUID` was allocated on heap we use the `FreePool` function after the print statement. + +## `NAME=` + +To print `NAME=` data we use the `NameFromCfgString` helper function: +```cpp +CHAR16* Name; +NameFromCfgString(&ConfigString[StrLen(L"NAME=")], StrLen(ConfigString) - StrLen(L"NAME="), &Name); +Print(L"%s (%s)\n", ConfigString, Name); +FreePool(Name); +``` + +This function looks like this: +```cpp +EFI_STATUS NameFromCfgString(CHAR16* CfgString, UINTN Size, CHAR16** Name) +{ + *Name = AllocateZeroPool(Size * sizeof(CHAR16)); + CHAR16 TempStr[4]; + for (UINTN i=0; iType == 0) || (DevicePathTest->SubType == 0) || (DevicePathNodeLength(DevicePathTest) < sizeof(EFI_DEVICE_PATH_PROTOCOL))) + return EFI_NOT_FOUND; + DevicePathTest = NextDevicePathNode (DevicePathTest); + } + + return EFI_SUCCESS; +} +``` + +As here we use device path library utilities don't forget to add `DevicePathLib` to the `[LibraryClasses]` in the `UefiLessonsPkg/HIIConfig/HIIConfig.inf` file and add its header `#include ` to the `UefiLessonsPkg/HIIConfig/HIIConfig.c` file. + +## `VALUE=` + +Handling code for `VALUE=` key looks like this: +```cpp +PrintLongString(ConfigString); +Print(L"\n"); +UINT8* Buffer; +UINTN BufferSize; +ByteCfgStringToBufferReversed(&ConfigString[StrLen(L"VALUE=")], StrLen(&ConfigString[StrLen(L"VALUE=")]), &Buffer, &BufferSize); +PrintBuffer(Buffer, BufferSize); +FreePool(Buffer); +``` +In this case we first print data as a string. But because it can be longer than `gEfiMdePkgTokenSpaceGuid.PcdUefiLibMaxPrintBufferSize`, we can't just use ordinary `Print` statement. We use our custom `PrintLongString` function that prints `<...>` at the end of a string that will be truncated on an ordinary print. This way we have a clear way to see if the output is complete or not: +```cpp +VOID PrintLongString(CHAR16* Str) +{ + UINT32 MaxPrintBufferSize = PcdGet32(PcdUefiLibMaxPrintBufferSize); + if (StrLen(Str) > MaxPrintBufferSize) { + EFI_STRING TempStr = (EFI_STRING)AllocateZeroPool(MaxPrintBufferSize * sizeof (CHAR16)); + CopyMem(TempStr, Str, MaxPrintBufferSize * sizeof (CHAR16)); + TempStr[MaxPrintBufferSize-1]=0; + TempStr[MaxPrintBufferSize-2]=L'>'; + TempStr[MaxPrintBufferSize-3]=L'.'; + TempStr[MaxPrintBufferSize-4]=L'.'; + TempStr[MaxPrintBufferSize-5]=L'.'; + TempStr[MaxPrintBufferSize-6]=L'<'; + Print(L"%s", TempStr); + FreePool(TempStr); + } else { + Print(L"%s", Str); + } +} +``` +Next we want to get the actual data in the array. The data after the `VALUE=` key is encoded in bytes, but the order is reversed. That means that data like this: +``` +VALUE=112233445566 +``` +actually corresponds to a byte array: +```cpp +{0x66, 0x55, 0x44, 0x33, 0x22, 0x11} +``` +That is why we use different function to get the byte array than in `GUID=` or `PATH=` cases. `ByteCfgStringToBufferReversed` is a little bit different than `ByteCfgStringToBuffer`: +```cpp +VOID ByteCfgStringToBufferReversed(CHAR16* CfgString, UINTN CfgStringLen, UINT8** Buffer, UINTN* BufferSize) +{ + *BufferSize = (CfgStringLen + 1) / 2; + *Buffer = (UINT8*)AllocateZeroPool(*BufferSize); + UINT8 DigitUint8; + CHAR16 TempStr[2] = {0}; + for (INTN Index = (CfgStringLen-1); Index >= 0; Index--) { + TempStr[0] = CfgString[Index]; + DigitUint8 = (UINT8)StrHexToUint64(TempStr); + if (((CfgStringLen-1-Index) & 1) == 0) { + (*Buffer)[(CfgStringLen-1-Index)/2] = DigitUint8; + } else { + (*Buffer)[(CfgStringLen-1-Index)/2] = (UINT8)((DigitUint8 << 4) + (*Buffer)[(CfgStringLen-1-Index)/2]); + } + } +} +``` + +Finally we display the value buffer similar to the Linux `hexdump -C` utility output: +```cpp +VOID PrintBuffer(UINT8* Buffer, UINTN Size) +{ + UINTN i = 0; + while (i < Size) { + Print(L"%02x ", Buffer[i]); + i++; + if (!(i%16)) { + Print(L" | "); + for (UINTN j=16; j>0; j--) + if ((Buffer[i-j] >= 0x20) && (Buffer[i-j] < 0x7E)) + Print(L"%c", Buffer[i-j]); + else + Print(L"."); + Print(L"\n"); + } + } + + if (i%16) { + for (UINTN j=0; j<=15; j++) { + if ((i+j)%16) + Print(L" "); + else + break; + } + Print(L" | "); + + for (UINTN j=(i%16); j>0; j--) { + if ((Buffer[i-j] >= 0x20) && (Buffer[i-j] < 0x7E)) + Print(L"%c", Buffer[i-j]); + else + Print(L"."); + } + Print(L"\n"); + } +} +``` + +# Putting it all together + +Now when we have all the parsing code we can finally test it. Here is the output of the `HIIConfig.efi dump` command. I've just truncated the bunch of zeros in the middle for a better readability: +``` +FS0:\> HIIConfig.efi dump +Full configuration for the HII Database (Size = 42018): +
