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.

In edit or hexedit, the mouse cursor doesn't move when moving

The root cause is 5563281fa2
* ShellPkg/[hex]edit: use SimpleTextInEx to read console
wrongly uses WaitForEvent() to listen keyboard input.
It blocks the code execution when there is no keyboard input.
While the same function also polls the mouse move status,
the mouse movement cannot be reflected to the screen when
there is no keyboard input.
The patch fixes the issue by use CheckEvent() instead of

Edit and HexEdit commands assume that SimpleTxtIn translates
Ctrl+<Alpha-Key> key combinations into Unicode control characters
(0x1-0x1A).
Such translation does not seem to be required by the UEFI spec.
Shell should not rely on implementation specific behavior.
It should instead use SimpleTextInEx to read Ctrl+<Alpha-Key> key
combinations.
The patch changes edit and hexedit to only consumes SimpleTextInEx
so that the implementation specific behavior dependency is removed.

An ordinary empty directory should contain "." and ".." entries.
When an empty directory even doesn't contain "." or ".." entry,

FileInfo.
IsDirectoryEmpty() implementation in Rm.c doesn't consider this

"Compress.h" declares the Compress() function as EFIAPI, but the
definition in "Compress.c" lacks EFIAPI.
GCC toolchains without LTO do not catch this error because "Compress.c"
does not include "Compress.h"; i.e. the declaration used by callers such
as "EfiCompress.c" is not actually matched against the function definition
at build time.
With LTO enabled, the mismatch is found -- however, as a warning only, due
to commit f8d0b96629 ("BaseTools GCC5: disable warnings-as-errors for
now", 2016-08-03).
Include the header in the C file (which turns the issue into a hard build
error on all GCC toolchains), plus sync the declaration from the header
file to the C file. Finally, remove EFIAPI from both declaration and
definition -- this was the original intent of commit c4e74e9b81
("ShellPkg/UefiShellDebug1CommandsLib: Remove unnecessary EFIAPI",
2016-10-09), but it missed the header file.
(Gary meant to address that omission in Oct 2017:
[edk2] [PATCH] ShellPkg/UefiShellDebug1CommandsLib: Remove EFIAPI from
Compress()
http://mid.mail-archive.com/20171026065329.32311-1-glin@suse.com
and Ray reviewed the patch, but then the patch was never committed.)
So do the sync and drop EFIAPI now.
This happens to fix the EFICOMPRESS shell command, when built with GCC for
X64.

In the for-loop condition of original code, the expression

When CurrentCommand walks to the end of string buffer, one more character
over the end of string buffer will be read and then stop.
To fix this issue, just move the last expression to the first one. Because
of short-circuit evaludation of and-expression, the following one
*CurrentCommand != CHAR_NULL

UefiShellLevel2CommandsLib (somewhat questionably) calls the
BaseLib-internal function InternalCharToUpper().
This function is declared in "MdePkg/Library/BaseLib/BaseLibInternals.h",
which is not a public library class header. UefiShellLevel2CommandsLib
therefore duplicates the function declaration, but a mistake was made: the
EFIAPI calling convention is not spelled out on the duplicated
declaration. Therefore calls made from UefiShellLevel2CommandsLib will not
match the actual function definition in "MdePkg/Library/BaseLib/String.c",
when GCC/X64 toolchains are used.
One consequence of this is that cross-filesystem copies don't work in the
UEFI shell (see the StrniCmp() function in
"UefiShellLevel2CommandsLib.c"). From the original report:
> FS0:\efi\ubuntu\> cp grubx64.efi fs1:\
>
> cp: The source and destination are the same.
Copy the declaration from "BaseLibInternals.h" to
"UefiShellLevel2CommandsLib.c" verbatim.

The previous change in ShellLib: "commit
3d29f8c5e3
* ShellPkg/ShellLib: Constructor doesn't depend on ShellParameters"
resolved the issue when loading dynamic command driver from Shell
environment.
But when dynamic command driver is built into FV and started during
boot, the driver still fails to start because Shell protocol doesn't
exist at that time.
The patch changes ShellLib to:
1. Do not look for Shell and ShellParameters protocol when they are
non-NULL in ShellLibConstructorWorker();
The two protocols are assumed to be set by DynamicCommand.Handler.
When ShellInitialize() is called in DynamicCommand.Handler, this
change can prevent the two protocols to be changed to NULL by
the locating logic.
2. Do not reset the Shell and ShellParameters protocol to NULL in
ShellLibDestructor() when CloseProtocol() fails;
Dynamic command driver needs to set the PcdShellLibAutoInitialize
to FALSE in order to skip the constructor.
Current logic calls ShellLibDestructor() when the PCD is FALSE when
ShellInitialize() is called. The change prevent the two protocols
to be changed to NULL.
The two changes don't impact existing usage case so they are backward
compatible.
