-The latest ACPI specification can be found under UEFI specifications page https://uefi.org/specifications
-
-The current latest specification is "ACPI Specification Version 6.4 (released January 2021)" (https://uefi.org/specs/ACPI/6.4/)
-
-
-Use the same tactic we used for SMBIOS tables to print ACPI entry point table address:
-```
-#include <Library/UefiBootServicesTableLib.h>
-#include <Library/UefiLib.h>
-
-#include <Library/BaseMemoryLib.h>
-
-EFI_STATUS
-EFIAPI
-UefiMain (
-  IN EFI_HANDLE        ImageHandle,
-  IN EFI_SYSTEM_TABLE  *SystemTable
-  )
-{
-  for (UINTN i=0; i<SystemTable->NumberOfTableEntries; i++) {
-    if (CompareGuid(&(SystemTable->ConfigurationTable[i].VendorGuid), &gEfiAcpi20TableGuid)) {
-      Print(L"ACPI table is placed at %p\n\n", SystemTable->ConfigurationTable[i].VendorTable);
-    }
-  }
-  return EFI_SUCCESS;
-}
-```
-
-Use `dmem` to peak inside ACPI table memory:
-```
-FS0:\> AcpiInfo.efi
-ACPI table is placed at 7B7E014
-
-FS0:\> dmem 7B7E014 30
-Memory Address 0000000007B7E014 30 Bytes
-  07B7E014: 52 53 44 20 50 54 52 20-4E 42 4F 43 48 53 20 02  *RSD PTR NBOCHS .*
-  07B7E024: 74 D0 B7 07 24 00 00 00-E8 D0 B7 07 00 00 00 00  *t...$...........*
-  07B7E034: 66 00 00 00 AF AF AF AF-AF AF AF AF AF AF AF AF  *f...............*
-FS0:\>
-```
-
-The signature `RSP PTR` stands for `Root System Description Pointer (RSDP) Structure` (https://uefi.org/specs/ACPI/6.4/05_ACPI_Software_Programming_Model/ACPI_Software_Programming_Model.html#root-system-description-pointer-rsdp-structure).
-
-It contains addresses for `RSDT` and `XSDT` tables. If you calculate offsets, you'll get these addresses from our memory dump:
-```
-XSDT=0x07B7D0E8
-RSDT=0x07B7D074
-```
-These tables in turn would cointain pointers to other ACPI tables that actualy contain data useful to OS.
-
-According to the spec "platforms provide the RSDT to enable compatibility with ACPI 1.0 operating systems. The XSDT supersedes RSDT functionality". So if you peak these addresses with `dmem`, table contents would be pretty much the same except table signatures. Therefore in our app code we would be parsing XSDT table data.
-
-Ok, it's time to write some code. ACPI structures are defined in the following header files:
-```
-$ ls -1 MdePkg/Include/IndustryStandard/Acpi*
-MdePkg/Include/IndustryStandard/Acpi.h
-MdePkg/Include/IndustryStandard/Acpi10.h
-MdePkg/Include/IndustryStandard/Acpi20.h
-MdePkg/Include/IndustryStandard/Acpi30.h
-MdePkg/Include/IndustryStandard/Acpi40.h
-MdePkg/Include/IndustryStandard/Acpi50.h
-MdePkg/Include/IndustryStandard/Acpi51.h
-MdePkg/Include/IndustryStandard/Acpi60.h
-MdePkg/Include/IndustryStandard/Acpi61.h
-MdePkg/Include/IndustryStandard/Acpi62.h
-MdePkg/Include/IndustryStandard/Acpi63.h
-MdePkg/Include/IndustryStandard/AcpiAml.h
-```
-
-Keep in mind that headers for latter standards include headers for earlier standards in itself.
-```
-Acpi.h > Acpi63.h > Acpi62.h > ... > Acpi10.h > AcpiAml.h
-```
-
-Let's look at RSDP structure definition at the most latest ACPI standard header file
-https://github.com/tianocore/edk2/blob/master/MdePkg/Include/IndustryStandard/Acpi63.h
-```
-///
-/// Root System Description Pointer Structure
-///
-typedef struct {
-  UINT64  Signature;
-  UINT8   Checksum;
-  UINT8   OemId[6];
-  UINT8   Revision;
-  UINT32  RsdtAddress;
-  UINT32  Length;
-  UINT64  XsdtAddress;
-  UINT8   ExtendedChecksum;
-  UINT8   Reserved[3];
-} EFI_ACPI_6_3_ROOT_SYSTEM_DESCRIPTION_POINTER;
-```
-
-We can use it to print addresses of RSDT/XSDT tables.
-```
-EFI_ACPI_6_3_ROOT_SYSTEM_DESCRIPTION_POINTER* RSDP = NULL;
-
-for (UINTN i=0; i<SystemTable->NumberOfTableEntries; i++) {
-  if (CompareGuid(&(SystemTable->ConfigurationTable[i].VendorGuid), &gEfiAcpi20TableGuid)) {
-    Print(L"RSDP table is placed at %p\n\n", SystemTable->ConfigurationTable[i].VendorTable);
-    RSDP = SystemTable->ConfigurationTable[i].VendorTable;
-  }
-}
-
-if (!RSDP) {
-  Print(L"No ACPI2.0 table was found in the system\n");
-  return EFI_SUCCESS;
-}
-
-if (((CHAR8)((RSDP->Signature >>  0) & 0xFF) != 'R') ||
-    ((CHAR8)((RSDP->Signature >>  8) & 0xFF) != 'S') ||
-    ((CHAR8)((RSDP->Signature >> 16) & 0xFF) != 'D') ||
-    ((CHAR8)((RSDP->Signature >> 24) & 0xFF) != ' ') ||
-    ((CHAR8)((RSDP->Signature >> 32) & 0xFF) != 'P') ||
-    ((CHAR8)((RSDP->Signature >> 40) & 0xFF) != 'T') ||
-    ((CHAR8)((RSDP->Signature >> 48) & 0xFF) != 'R') ||
-    ((CHAR8)((RSDP->Signature >> 56) & 0xFF) != ' ')) {
-  Print(L"Error! RSDP signature is not valid!\n");
-  return EFI_SUCCESS;
-}
-
-Print(L"System description tables:\n");
-Print(L"\tRSDT table is placed at address %p\n", RSDP->RsdtAddress);
-Print(L"\tXSDT table is placed at address %p\n", RSDP->XsdtAddress);
-Print(L"\n");
-```
-
-In the same file (https://github.com/tianocore/edk2/blob/master/MdePkg/Include/IndustryStandard/Acpi63.h) you can find description for XSDT structure:
-```
-//
-// Extended System Description Table
-// No definition needed as it is a common description table header, the same with
-// EFI_ACPI_DESCRIPTION_HEADER, followed by a variable number of UINT64 table pointers.
-//
-```
-
-The definition for `EFI_ACPI_DESCRIPTION_HEADER` can be found here https://github.com/tianocore/edk2/blob/master/MdePkg/Include/IndustryStandard/Acpi10.h:
-```
-#pragma pack(1)
-///
-/// The common ACPI description table header.  This structure prefaces most ACPI tables.
-///
-typedef struct {
-  UINT32  Signature;
-  UINT32  Length;
-  UINT8   Revision;
-  UINT8   Checksum;
-  UINT8   OemId[6];
-  UINT64  OemTableId;
-  UINT32  OemRevision;
-  UINT32  CreatorId;
-  UINT32  CreatorRevision;
-} EFI_ACPI_DESCRIPTION_HEADER;
-#pragma pack()
-```
-
-Let's check information about other ACPI tables that are present in the system:
-```
-EFI_ACPI_DESCRIPTION_HEADER* XSDT = (EFI_ACPI_DESCRIPTION_HEADER*)RSDP->XsdtAddress;
-if (((CHAR8)((XSDT->Signature >>  0) & 0xFF) != 'X') ||
-    ((CHAR8)((XSDT->Signature >>  8) & 0xFF) != 'S') ||
-    ((CHAR8)((XSDT->Signature >> 16) & 0xFF) != 'D') ||
-    ((CHAR8)((XSDT->Signature >> 24) & 0xFF) != 'T')) {
-  Print(L"Error! XSDT signature is not valid!\n");
-  return EFI_SUCCESS;
-}
-
-Print(L"Main ACPI tables:\n");
-UINT64 offset = sizeof(EFI_ACPI_DESCRIPTION_HEADER);
-while (offset < XSDT->Length) {
-  UINT64* table_address = (UINT64*)((UINT8*)XSDT + offset);
-  EFI_ACPI_6_3_COMMON_HEADER* table = (EFI_ACPI_6_3_COMMON_HEADER*)(*table_address);
-  TableName[0] = (CHAR16)((table->Signature>> 0)&0xFF);
-  TableName[1] = (CHAR16)((table->Signature>> 8)&0xFF);
-  TableName[2] = (CHAR16)((table->Signature>>16)&0xFF);
-  TableName[3] = (CHAR16)((table->Signature>>24)&0xFF);
-  TableName[4] = 0;
-
-  Print(L"\t%s table is placed at address %p with length 0x%x\n",
-                                           TableName,
-                                           table,
-                                           table->Length);
-  offset += sizeof(UINT64);
-}
-```
-
-If you build our app and execute it under OVMF now you would get:
-```
-FS0:\> AcpiInfo.efi
-RSDP table is placed at 7B7E014
-
-System description tables:
-        RSDT table is placed at address 7B7D074
-        XSDT table is placed at address 7B7D0E8
-
-Main ACPI tables:
-        FACP table is placed at address 7B7A000 with length 0x74
-        APIC table is placed at address 7B79000 with length 0x78
-        HPET table is placed at address 7B78000 with length 0x38
-        BGRT table is placed at address 7B77000 with length 0x38
-```
-
-Pretty neat, our system has 4 ACPI data tables:
-- Fixed ACPI Description Table (`FACP`) - https://uefi.org/specs/ACPI/6.4/05_ACPI_Software_Programming_Model/ACPI_Software_Programming_Model.html#fixed-acpi-description-table-fadt
-- Multiple APIC Description Table (`MADT`) - https://uefi.org/specs/ACPI/6.4/05_ACPI_Software_Programming_Model/ACPI_Software_Programming_Model.html#multiple-apic-description-table-madt
-- IA-PC High Precision Event Timer Table (`HPET`) - http://www.intel.com/content/dam/www/public/us/en/documents/technical-specifications/software-developers-hpet-spec-1-0a.pdf - This one is not present in ACPI spec, but in a separate document from the page https://uefi.org/acpi
-- Boot Graphics Resource Table (`BGRT`) - https://uefi.org/specs/ACPI/6.4/05_ACPI_Software_Programming_Model/ACPI_Software_Programming_Model.html#boot-graphics-resource-table-bgrt
-
-
-Keep in mind that as with SMBIOS tables we could use a protocol to get the same data. `GetAcpiTable()` function of a `EFI_ACPI_SDT_PROTOCOL` can help to get the same information. This protocol also is defined by UEFI PI specification.
-
-In edk2 it is defined under https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Protocol/AcpiSystemDescriptionTable.h
-
-# Use `EFI_SHELL_PROTOCOL` to save table data
-
-Now let's try to save ACPI tables from memory to files.
-
-To do this we can utilize `EFI_SHELL_PROTOCOL` that is defined in UEFI Shell specification (https://uefi.org/sites/default/files/resources/UEFI_Shell_2_2.pdf). It has many functions for File I/O.
-
-The necessary header in edk2 is https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Protocol/Shell.h
-```
-typedef struct _EFI_SHELL_PROTOCOL {
-  EFI_SHELL_EXECUTE                         Execute;
-  EFI_SHELL_GET_ENV                         GetEnv;

-  EFI_SHELL_OPEN_ROOT                       OpenRoot;
-  EFI_SHELL_OPEN_ROOT_BY_HANDLE             OpenRootByHandle;
-  EFI_EVENT                                 ExecutionBreak;
-  UINT32                                    MajorVersion;
-  UINT32                                    MinorVersion;

-  EFI_SHELL_GET_ENV_EX                      GetEnvEx;
-} EFI_SHELL_PROTOCOL;
-```
-
-We will use 3 functions from this protocol `OpenFileByName`/`WriteFile`/`CloseFile`:
-```
-EFI_SHELL_PROTOCOL.OpenFileByName()
-
-Summary:
-Opens a file or a directory by file name.
-
-Prototype:
-typdef
-EFI_STATUS
-(EFIAPI *EFI_SHELL_OPEN_FILE_BY_NAME) (
- IN CONST CHAR16 *FileName,
- OUT SHELL_FILE_HANDLE *FileHandle,
- IN UINT64 OpenMode
- );
-
-Parameters:
-FileName	Points to the null-terminated UCS-2 encoded file name.
-FileHandle	On return, points to the file handle.
-OpenMode	File open mode.
-
-Description:
-This function opens the specified file in the specified OpenMode and returns a file handle.
-```
-```
-EFI_SHELL_PROTOCOL.WriteFile()
-
-Summary:
-Writes data to the file.
-
-Prototype:
-typedef
-EFI_STATUS
-(EFIAPI EFI_SHELL_WRITE_FILE)(
- IN SHELL_FILE_HANDLE FileHandle,
- IN OUT UINTN *BufferSize,
- OUT VOID *Buffer
- );
-
-Parameters:
-FileHandle 	The opened file handle for writing.
-BufferSize	On input, size of Buffer.
-Buffer		The buffer in which data to write.
-
-Description:
-This function writes the specified number of bytes to the file at the current file position. The current file position is advanced the actual number of bytes
-written, which is returned in BufferSize. Partial writes only occur when there has been a data error during the write attempt (such as “volume space full”).
-The file automatically grows to hold the data, if required.
-```
-```
-EFI_SHELL_PROTOCOL.CloseFile()
-
-Summary:
-Closes the file handle.
-
-Prototype:
-typedef
-EFI_STATUS
-(EFIAPI *EFI_SHELL_CLOSE_FILE)(
- IN SHELL_FILE_HANDLE FileHandle
- );
-
-Parameters:
-FileHandle	The file handle to be closed
-Description	This function closes a specified file handle. All “dirty” cached file data is flushed
-		to the device, and the file is closed. In all cases, the handle is closed.
-
-```
-
-Now let's start coding. Add necessary include to our *.c file:
-```
-#include <Protocol/Shell.h>
-```
-And necessary protocol guid to our *.inf file:
-```
-[Protocols]
-  gEfiShellProtocolGuid
-```
-
-In our program we need to acquire `EFI_SHELL_PROTOCOL`, this can be done via `LocateProtocol` function from the BootServices:
-```
-EFI_SHELL_PROTOCOL* ShellProtocol;
-EFI_STATUS Status = gBS->LocateProtocol(
-  &gEfiShellProtocolGuid,
-  NULL,
-  (VOID **)&ShellProtocol
-);
-
-if (EFI_ERROR(Status)) {
-  Print(L"Can't open EFI_SHELL_PROTOCOL: %r\n", Status);
-  return EFI_SUCCESS;
-}
-```
-
-Then use `EFI_SHELL_PROTOCOL` functions in our while loop to create files with ACPI table data. For every table we will create a file "<signature>.aml". We use `.aml` extension for our files because in ACPI language source files usually have *.asl/*.dsl extension (ACPI Source Language), and compiled files have *.aml extension (ACPI Machine Language):
-```
-CHAR16 FileName[9] = {0};
-StrCpyS(FileName, 9, TableName);
-StrCatS(FileName, 9, L".aml");
-Print(L"%s\n", FileName);
-SHELL_FILE_HANDLE FileHandle;
-Status = ShellProtocol->OpenFileByName(FileName,
-                                       &FileHandle,
-                                       EFI_FILE_MODE_CREATE | EFI_FILE_MODE_WRITE | EFI_FILE_MODE_READ);
-
-if (!EFI_ERROR(Status)) {
-  UINTN size = table->Length;
-  Status = ShellProtocol->WriteFile(FileHandle, &size, (VOID*)table);
-  if (EFI_ERROR(Status)) {
-    Print(L"Error in WriteFile: %r\n", Status);
-  }
-  Status = ShellProtocol->CloseFile(FileHandle);
-  if (EFI_ERROR(Status)) {
-    Print(L"Error in CloseFile: %r\n", Status);
-  }
-} else {
-  Print(L"Error in OpenFileByName: %r\n", Status);
-}
-```
-
-To create a string with a file name we use `StrCatS` and `StrCpyS` functions. They are safe versions of string concatention/string copy functions similar to their C++ analogs `strcat_s`/`strcpy_s`. You can check out them in a library https://github.com/tianocore/edk2/blob/master/MdePkg/Library/BaseLib/SafeString.c
-
-With a help of `EFI_SHELL_PROTOCOL` file operation functions writing data to a file is pretty similar to standard system programming. We open handle, write data to it, and finally close handle.
-
-If you build our app and execute it under OVMF you would get 4 files in our `UEFI_disk` shared folder:
-```
-$ ls -1 ~/UEFI_disk/*.aml
-/home/kostr/UEFI_disk/apic.aml
-/home/kostr/UEFI_disk/bgrt.aml
-/home/kostr/UEFI_disk/facp.aml
-/home/kostr/UEFI_disk/hpet.aml
-```
-
-You can use `iasl` compiler to disassemle ACPI table data:
-```
-$ iasl -d ~/UEFI_disk/*.aml
