> Subject: [PATCH v3 1/1] ShellPkg: Add acpiview tool to dump ACPI tables
> Importance: High
>
> 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.

> 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

Firstly, public library APIs should have "EFIAPI" decorator.
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.
Thanks/Ray

> Notes:
> 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]

> +"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"

> +" \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"
