This program is provided to allow examination of ACPI table contents
from the UEFI Shell. This can help with investigations, especially at
that stage where the tables are not enabling an OS to boot.
The program is not exhaustive, and only encapsulates detailed knowledge
of a limited number of table types.
Default behaviour is to display the content of all tables installed.
'Known' table types will be parsed and displayed with descriptions and
field values. Where appropriate a degree of consistency checking is
done and errors may be reported in the output.
Other table types will be displayed as an array of Hexadecimal bytes.
To facilitate debugging, the -s and -d options can be used to generate a
binary file image of a table that can be copied elsewhere for
investigation using tools such as those provided by acpica.org. This is
especially relevant for AML type tables like DSDT and SSDT.
The inspiration for this is the existing smbiosview Debug1 Shell
command.
Many tables are not explicitly handled, in part because no examples are
available for our testing.
The program is designed to be extended to new tables with minimal
effort, and contributions are invited.

The updated changes can be viewed at:
https://github.com/samimujawar/edk2/tree/188_acpiview_v4
Notes:
v4:
- Firstly, public library APIs should have "EFIAPI" decorator. [RAY]
- Resubmitting updated patch with "EFIAPI" decorator. [SAMI]
- Secondly, I am wondering if it's possible to not expose any
library classes for handling of more ACPI tables.
I agree to implement UefiShellAcpiViewCommandLib in a way for easy
extension for handling of more ACPI tables, but I prefer to keep the
interfaces internally inside the UefiShellAcpiViewCommandLib. [RAY]
- Updated as suggested. [SAMI]
v3:
- Can the individual "child" libraries be placed into
subdirectories under UefiShellAcpiViewCommandLib directory
for clear separation? [JABEN]
- Patch updated to move individual "child" libraries into
subdirectories. [SAMI]
- In UefiShellAcpiViewCommandLib,c what's the motivation for all
the wrappers around print? I see that some are for memory access
restrictions, but the rest? PrintGuid, looks the same as using
%g with Print()... [JABEN]
- The print wrappers enable a common styled formatted printing for
the ACPI fields. The ACPIview table parsing framework utilizes a
table-driven approach for parsing the tables and these functions
are invoked by the framework based on the field size and type.
However you are right, it is superfluous in the case of PrintGuid
(Which has now been removed in the updated patch). [SAMI]
- Do we want to change the main entrypoint to a DynamicCommand
since this command is not in the shell spec? If yes, do we want
to do that first or after? [JABEN]
- The ECR 1784 for ACPIview appears to be 'Approved as new content
for the Shell Spec.' in Mantis,
see https://mantis.uefi.org/mantis/view.php?id=1784.
As I understand it, the ECR change needs to be propagated to the
Shell specification and is pending. In light of the above, I think
that adding DynamicCommand support is not necessary. Please let me
know if you feel otherwise. [SAMI]

+" \r\n"
+"ACPIVIEW [[-?] | [[-l] | [-s AcpiTable [-d]]] [-c] [-v] [-h Highlight]]\r\n"
+" \r\n"
+".SH OPTIONS\r\n"
+" \r\n"
+" -l - Display list of installed ACPI Tables.\r\n"
+" -s - Display only the specified AcpiTable type.\r\n"
+" AcpiTable : The required ACPI Table type.\r\n"
+" -d - Generate a binary file dump of the specified AcpiTable.\r\n"
+" -c - Consistency checking (enabled by default).\r\n"
+" -v - Display verbose data (enabled by default).\r\n"
+" -h - Enable/Disable Colour Highlighting.\r\n"
+" Highlight : TRUE/ON enables highlighting;\r\n"
+" FALSE/OFF (default) disables highlighting.\r\n"
+" -? - Show help.\r\n"
+" \r\n"
+".SH DESCRIPTION\r\n"
+" \r\n"
+" This program is provided to allow examination of ACPI table values from the\r\n"
+" UEFI Shell. This can help with investigations, especially at that stage where\r\n"
+" the tables are not enabling an OS to boot.\r\n"
+" The program is not exhaustive, and only encapsulates detailed knowledge of a\r\n"
+" limited number of table types.\r\n"
+" \r\n"
+" Default behaviour is to display the content of all tables installed.\r\n"
+" 'Known' table types (listed in NOTES below) will be parsed and displayed\r\n"
+" with descriptions and field values. Where appropriate a degree of consistency\r\n"
+" checking is done and errors may be reported in the output.\r\n"
+" Other table types will be displayed as an array of Hexadecimal bytes.\r\n"
+" \r\n"
+" To facilitate debugging, the -s and -d options can be used to generate a\r\n"
+" binary file image of a table that can be copied elsewhere for investigation\r\n"
+" using tools such as those provided by acpica.org. This is especially relevant\r\n"
+" for AML type tables like DSDT and SSDT.\r\n"
+" \r\n"
+"NOTES:\r\n"
+" 1. The AcpiTable parameter can match any installed table type.\r\n"
+" Tables without specific handling will be displayed as a raw hex dump (or\r\n"
+" dumped to a file if -d is used).\r\n"
+" 2. Formatted display and checking is provided for these signature types:\r\n"
+" APIC - Multiple APIC Description Table (MADT)\r\n"
+" BGRT - Boot Graphics Resource Table\r\n"
+" DBG2 - Debug Port Table 2\r\n"
+" FACP - Fixed ACPI Description Table (FADT)\r\n"
+" GTDT - Generic Timer Description Table\r\n"
+" IORT - IO Remapping Table\r\n"
+" MCFG - Memory Mapped Config Space Base Address Description Table\r\n"
+" RSDP - Root System Description Pointer\r\n"
+" SLIT - System Locality Information Table\r\n"
+" SPCR - Serial Port Console Redirection Table\r\n"
+" SRAT - System Resource Affinity Table\r\n"
+" XSDT - Extended System Description Table\r\n"
+" \r\n"
+".SH STANDARDS\r\n"
+" \r\n"
+" Table details correspond to those in 'Advanced Configuration and Power\r\n"
+" Interface Specification' Version 6.2 Errata A, [September 2017]\r\n"
+" (http://www.uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf)\r\n"
+" \r\n"
+" NOTE: The nature of the ACPI standard means that almost all tables in 6.1 will\r\n"
+" be 'backwards compatible' with prior version of the specification in\r\n"
+" terms of structure, so formatted output should be correct. The main\r\n"
+" exception will be that previously 'reserved' fields will be reported\r\n"
+" with new names, where they have been added in later versions of the\r\n"
+" specification.\r\n"
+" \r\n"
+".SH EXAMPLES\r\n"
+" \r\n"
+" \r\n"
+"EXAMPLES:\r\n"
+" * To display a list of the installed table types:\r\n"
+" fs0:\> acpiview -l\r\n"
+" \r\n"
+" * To parse and display a specific table type:\r\n"
+" fs0:\> acpiview -s GTDT\r\n"
+" \r\n"
+" * To save a binary dump of the contents of a table to a file\r\n"
+" in the current working directory:\r\n"
+" fs0:\> acpiview -s DSDT -d\r\n"
+" \r\n"
+" * To display contents of all ACPI tables:\r\n"
+" fs0:\> acpiview\r\n"
+" \r\n"
+".SH RETURNVALUES\r\n"
+" \r\n"
+"RETURN VALUES:\r\n"
+" SHELL_SUCCESS Data was displayed as requested.\r\n"
+" SHELL_INVALID_PARAMETER ACPI Table parsing failed.\r\n"
+" \r\n"

Hi Ray,
Please see my response below marked [SAMI].
>> ShellPkg/Include/Library/AcpiView/AcpiParser.h | 449 ++++++++++++
>> ShellPkg/Include/Library/AcpiView/AcpiTableParser.h | 126 ++++
> Sami, should the above two new files be removed?
[SAMI] The individual table parsers are implemented as NULL libraries that register the parser with UefiShellAcpiViewCommandLib. These parser libraries are present in sub folders e.g. ShellPkg/Library/UefiShellAcpiViewCommandLib/Parsers/Bgrt; a change that was introduced in the v3 patch in response to review comments. For building the parser libraries, I need a mechanism to get the include path to the header files above (which expose the parser registration functions and the common functionality implemented in UefiShellAcpiViewCommandLib). Therefore, I have kept them under ShellPkg/Include/Library/AcpiView.
> Since per your comments, the interfaces are kept inside UefiShellAcpiViewCommandLib.
[SAMI] It looks like I had not fully understood your #2 comment. I had a helper library for exposing the registration functions and common functionality. I moved this functionality to keep these interfaces inside UefiShellAcpiViewCommandLib.
However as explained above I have the common functionality implemented as part of the UefiShellAcpiViewCommandLib which is utilized by individual parsers.
Considering the above I hope the patch OK. Alternatively, if you can advise me on a better way of achieving this, I will be happy to incorporate the changes.
Regards,
Sami Mujawar

Sami, should the above two new files be removed?
Since per your comments, the interfaces are kept inside
UefiShellAcpiViewCommandLib.

> +" \r\n"
> +".SH OPTIONS\r\n"
> +" \r\n"
> +" -l - Display list of installed ACPI Tables.\r\n"
> +" -s - Display only the specified AcpiTable type.\r\n"
> +" AcpiTable : The required ACPI Table type.\r\n"
> +" -d - Generate a binary file dump of the specified AcpiTable.\r\n"
> +" -c - Consistency checking (enabled by default).\r\n"
> +" -v - Display verbose data (enabled by default).\r\n"
> +" -h - Enable/Disable Colour Highlighting.\r\n"

> +" \r\n"
> +".SH DESCRIPTION\r\n"
> +" \r\n"
> +" This program is provided to allow examination of ACPI table values from the\r\n"
> +" UEFI Shell. This can help with investigations, especially at that stage where\r\n"
> +" the tables are not enabling an OS to boot.\r\n"
> +" The program is not exhaustive, and only encapsulates detailed knowledge of a\r\n"
> +" limited number of table types.\r\n"
> +" \r\n"
> +" Default behaviour is to display the content of all tables installed.\r\n"
> +" 'Known' table types (listed in NOTES below) will be parsed and displayed\r\n"
> +" with descriptions and field values. Where appropriate a degree of consistency\r\n"
> +" checking is done and errors may be reported in the output.\r\n"
> +" Other table types will be displayed as an array of Hexadecimal bytes.\r\n"
> +" \r\n"
> +" To facilitate debugging, the -s and -d options can be used to generate a\r\n"
> +" binary file image of a table that can be copied elsewhere for investigation\r\n"
> +" using tools such as those provided by acpica.org. This is especially relevant\r\n"
> +" for AML type tables like DSDT and SSDT.\r\n"
> +" \r\n"
> +"NOTES:\r\n"
> +" 1. The AcpiTable parameter can match any installed table type.\r\n"
> +" Tables without specific handling will be displayed as a raw hex dump (or\r\n"
> +" dumped to a file if -d is used).\r\n"
> +" 2. Formatted display and checking is provided for these signature types:\r\n"
> +" APIC - Multiple APIC Description Table (MADT)\r\n"
> +" BGRT - Boot Graphics Resource Table\r\n"
> +" DBG2 - Debug Port Table 2\r\n"
> +" FACP - Fixed ACPI Description Table (FADT)\r\n"
> +" GTDT - Generic Timer Description Table\r\n"
> +" IORT - IO Remapping Table\r\n"
> +" MCFG - Memory Mapped Config Space Base Address Description Table\r\n"
> +" RSDP - Root System Description Pointer\r\n"
> +" SLIT - System Locality Information Table\r\n"
> +" SPCR - Serial Port Console Redirection Table\r\n"

Hi Ray,
Please see my response below marked [SAMI].
>> ShellPkg/Include/Library/AcpiView/AcpiParser.h | 449 ++++++++++++

> Sami, should the above two new files be removed?
[SAMI] The individual table parsers are implemented as NULL libraries that register the parser with UefiShellAcpiViewCommandLib. These parser libraries are present in sub folders e.g. ShellPkg/Library/UefiShellAcpiViewCommandLib/Parsers/Bgrt; a change that was introduced in the v3 patch in response to review comments. For building the parser libraries, I need a mechanism to get the include path to the header files above (which expose the parser registration functions and the common functionality implemented in UefiShellAcpiViewCommandLib). Therefore, I have kept them under ShellPkg/Include/Library/AcpiView.
> Since per your comments, the interfaces are kept inside UefiShellAcpiViewCommandLib.
[SAMI] It looks like I had not fully understood your #2 comment. I had a helper library for exposing the registration functions and common functionality. I moved this functionality to keep these interfaces inside UefiShellAcpiViewCommandLib.
However as explained above I have the common functionality implemented as part of the UefiShellAcpiViewCommandLib which is utilized by individual parsers.
Considering the above I hope the patch OK. Alternatively, if you can advise me on a better way of achieving this, I will be happy to incorporate the changes.
Regards,
Sami Mujawar

Sami, should the above two new files be removed?
Since per your comments, the interfaces are kept inside
UefiShellAcpiViewCommandLib.

> [SAMI] The individual table parsers are implemented as NULL libraries that register the parser with UefiShellAcpiViewCommandLib. These parser libraries are present in sub folders e.g. ShellPkg/Library/UefiShellAcpiViewCommandLib/Parsers/Bgrt; a change that was introduced in the v3 patch in response to review comments. For building the parser libraries, I need a mechanism to get the include path to the header files above (which expose the parser registration functions and the common functionality implemented in UefiShellAcpiViewCommandLib). Therefore, I have kept them under ShellPkg/Include/Library/AcpiView.
I prefer to keep the whole parser as a standalone library. I like the
idea to have a parser registration mechanism. But I don't think we need
to expose the registration API outside of the UefiShellAcpiViewCommandLib.
That's to say, anyone who wants to add parser for new tables can add a
new function/file inside UefiShellAcpiViewCommandLib. In order for the
main parser to call the new sub-parser, he can either directly modify
the function table to add a new entry, or call a internal registration
function which indirectly modifies the function table.

>> The updated changes can be viewed at:
>> https://github.com/samimujawar/edk2/tree/188_acpiview_v4
>>
>> Notes:
>> v4:
>> - Firstly, public library APIs should have "EFIAPI" decorator. [RAY]
>> - Resubmitting updated patch with "EFIAPI" decorator. [SAMI]
>>
>> - Secondly, I am wondering if it's possible to not expose any
>> library classes for handling of more ACPI tables.
>> I agree to implement UefiShellAcpiViewCommandLib in a way for easy
>> extension for handling of more ACPI tables, but I prefer to keep the
>> interfaces internally inside the UefiShellAcpiViewCommandLib. [RAY]
>> - Updated as suggested. [SAMI]
>>
>> v3:
>> - Can the individual "child" libraries be placed into
>> subdirectories under UefiShellAcpiViewCommandLib directory
>> for clear separation? [JABEN]
>> - Patch updated to move individual "child" libraries into
>> subdirectories. [SAMI]
>>
>> - In UefiShellAcpiViewCommandLib,c what's the motivation for all
>> the wrappers around print? I see that some are for memory access
>> restrictions, but the rest? PrintGuid, looks the same as using
>> %g with Print()... [JABEN]
>> - The print wrappers enable a common styled formatted printing for
>> the ACPI fields. The ACPIview table parsing framework utilizes a
>> table-driven approach for parsing the tables and these functions
>> are invoked by the framework based on the field size and type.
>> However you are right, it is superfluous in the case of PrintGuid
>> (Which has now been removed in the updated patch). [SAMI]
>>
>> - Do we want to change the main entrypoint to a DynamicCommand
>> since this command is not in the shell spec? If yes, do we want
>> to do that first or after? [JABEN]
>> - The ECR 1784 for ACPIview appears to be 'Approved as new content
>> for the Shell Spec.' in Mantis,
>> see https://mantis.uefi.org/mantis/view.php?id=1784.
>> As I understand it, the ECR change needs to be propagated to the
>> Shell specification and is pending. In light of the above, I think
>> that adding DynamicCommand support is not necessary. Please let me
>> know if you feel otherwise. [SAMI]

>> +" \r\n"
>> +".SH OPTIONS\r\n"

>> +" -l - Display list of installed ACPI Tables.\r\n"
>> +" -s - Display only the specified AcpiTable type.\r\n"
>> +" AcpiTable : The required ACPI Table type.\r\n"

>> +" \r\n"
>> +" This program is provided to allow examination of ACPI table values from the\r\n"
>> +" UEFI Shell. This can help with investigations, especially at that stage where\r\n"
>> +" the tables are not enabling an OS to boot.\r\n"
>> +" The program is not exhaustive, and only encapsulates detailed knowledge of a\r\n"
>> +" limited number of table types.\r\n"
>> +" \r\n"
>> +" Default behaviour is to display the content of all tables installed.\r\n"
>> +" 'Known' table types (listed in NOTES below) will be parsed and displayed\r\n"
>> +" with descriptions and field values. Where appropriate a degree of consistency\r\n"
>> +" checking is done and errors may be reported in the output.\r\n"
>> +" Other table types will be displayed as an array of Hexadecimal bytes.\r\n"
>> +" \r\n"
>> +" To facilitate debugging, the -s and -d options can be used to generate a\r\n"
>> +" binary file image of a table that can be copied elsewhere for investigation\r\n"
>> +" using tools such as those provided by acpica.org. This is especially relevant\r\n"
>> +" for AML type tables like DSDT and SSDT.\r\n"
>> +" \r\n"
>> +"NOTES:\r\n"
>> +" 1. The AcpiTable parameter can match any installed table type.\r\n"
>> +" Tables without specific handling will be displayed as a raw hex dump (or\r\n"
>> +" dumped to a file if -d is used).\r\n"
>> +" 2. Formatted display and checking is provided for these signature types:\r\n"
>> +" APIC - Multiple APIC Description Table (MADT)\r\n"
>> +" BGRT - Boot Graphics Resource Table\r\n"
>> +" DBG2 - Debug Port Table 2\r\n"
>> +" FACP - Fixed ACPI Description Table (FADT)\r\n"
>> +" GTDT - Generic Timer Description Table\r\n"
>> +" IORT - IO Remapping Table\r\n"
>> +" MCFG - Memory Mapped Config Space Base Address Description Table\r\n"
>> +" RSDP - Root System Description Pointer\r\n"
>> +" SLIT - System Locality Information Table\r\n"
>> +" SPCR - Serial Port Console Redirection Table\r\n"
>> +" SRAT - System Resource Affinity Table\r\n"
>> +" XSDT - Extended System Description Table\r\n"
>> +" \r\n"
>> +".SH STANDARDS\r\n"
>> +" \r\n"
>> +" Table details correspond to those in 'Advanced Configuration and Power\r\n"

>> +" (http://www.uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf)\r\n"
>> +" \r\n"
>> +" NOTE: The nature of the ACPI standard means that almost all tables in 6.1 will\r\n"
>> +" be 'backwards compatible' with prior version of the specification in\r\n"
>> +" terms of structure, so formatted output should be correct. The main\r\n"
>> +" exception will be that previously 'reserved' fields will be reported\r\n"
>> +" with new names, where they have been added in later versions of the\r\n"
>> +" specification.\r\n"
>> +" \r\n"
>> +".SH EXAMPLES\r\n"
>> +" \r\n"
>> +" \r\n"

Do we want to support parsing a non-ACPI spec defined ACPI table?
As such, exposing the API to let the table producer define its own parsing logic, instead of in ShellPkg.
Thank you

Please find my response below marked [SAMI].
Do we want to support parsing a non-ACPI spec defined ACPI table?
[SAMI] This is currently possible. One only needs to implement a parser for the custom ACPI table.
As such, exposing the API to let the table producer define its own parsing logic, instead of in ShellPkg.
[SAMI] This would be a possible change should you wish to contribute as a follow-on. Although the current code may be capable of extension, we think the current version is useful as is and suggests that such changes would be best made once the source is available in edk2.
Regards,
Sami Mujawar

I agree with Sami that we should add what we have.
Yao,

Jaben,
I agree with you. A new protocol is more proper.
But for now, let's remove any public library APIs.
Adding public APIs is very easy. But removing them is almost impossible.
If we think it's valuable to add them, we can add them in future.

>>>>> +" \r\n"
>>>>> +" This program is provided to allow examination of ACPI table values
>> from
>>> the\r\n"
>>>>> +" UEFI Shell. This can help with investigations, especially at that stage
>>> where\r\n"
>>>>> +" the tables are not enabling an OS to boot.\r\n"
>>>>> +" The program is not exhaustive, and only encapsulates detailed
>>> knowledge of a\r\n"
>>>>> +" limited number of table types.\r\n"
>>>>> +" \r\n"
>>>>> +" Default behaviour is to display the content of all tables installed.\r\n"
>>>>> +" 'Known' table types (listed in NOTES below) will be parsed and
>>> displayed\r\n"
>>>>> +" with descriptions and field values. Where appropriate a degree of
>>> consistency\r\n"
>>>>> +" checking is done and errors may be reported in the output.\r\n"
>>>>> +" Other table types will be displayed as an array of Hexadecimal
>>> bytes.\r\n"
>>>>> +" \r\n"
>>>>> +" To facilitate debugging, the -s and -d options can be used to
>> generate
>>> a\r\n"
>>>>> +" binary file image of a table that can be copied elsewhere for
>>> investigation\r\n"
>>>>> +" using tools such as those provided by acpica.org. This is especially
>>> relevant\r\n"
>>>>> +" for AML type tables like DSDT and SSDT.\r\n"
>>>>> +" \r\n"
>>>>> +"NOTES:\r\n"
>>>>> +" 1. The AcpiTable parameter can match any installed table type.\r\n"
>>>>> +" Tables without specific handling will be displayed as a raw hex
>> dump
>>> (or\r\n"
>>>>> +" dumped to a file if -d is used).\r\n"
>>>>> +" 2. Formatted display and checking is provided for these signature
>>> types:\r\n"
>>>>> +" APIC - Multiple APIC Description Table (MADT)\r\n"
>>>>> +" BGRT - Boot Graphics Resource Table\r\n"
>>>>> +" DBG2 - Debug Port Table 2\r\n"
>>>>> +" FACP - Fixed ACPI Description Table (FADT)\r\n"
>>>>> +" GTDT - Generic Timer Description Table\r\n"
>>>>> +" IORT - IO Remapping Table\r\n"
>>>>> +" MCFG - Memory Mapped Config Space Base Address Description
>>> Table\r\n"
>>>>> +" RSDP - Root System Description Pointer\r\n"
>>>>> +" SLIT - System Locality Information Table\r\n"

>>>
>> (http://www.uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.
>> pdf)
>>> \r\n"
>>>>> +" \r\n"
>>>>> +" NOTE: The nature of the ACPI standard means that almost all tables
>> in 6.1
>>> will\r\n"
>>>>> +" be 'backwards compatible' with prior version of the specification
>>> in\r\n"
>>>>> +" terms of structure, so formatted output should be correct. The
>>> main\r\n"
>>>>> +" exception will be that previously 'reserved' fields will be
>>> reported\r\n"
>>>>> +" with new names, where they have been added in later versions
>> of
>>> the\r\n"
>>>>> +" specification.\r\n"
>>>>> +" \r\n"
>>>>> +".SH EXAMPLES\r\n"
