Samer El-Haj-Mahmoud df77614e54 MdeModulePkg/ConSplitter: Change StdErr color to EFI_LIGHTGRAY
ConSplitter is using EFI_LIGHTGRAY foreground color for ConOut
and EFI_MAGENTA for StdErr consoles. This is impacting the DebugLib
output on that same serial console (e.g. DebugLibSerialPort) after
gEfiStandardErrorDeviceGuid is installed on that port. The impact
also extends to Linux serial console output in OVMF because it inherits
the color setting from the firmware.

This is inconsistent and annoying, with MAGENTA being barely legible on
a black background.

Let's change StdErr default color to LIGHTGRAY for consistency and
readability. This results in the same color being used for all consoles
sharing the same serial port (ConOut, StdErr, DebugLib, OS console).
Platforms wishing to distinguish the colors of consoles can do so in
their own Platform BDS initialization.

Samer El-Haj-Mahmoud b585238d33 MdeModulePkg/GraphicsConsoleDxe: Change default CursorVisible to FALSE
REF: https://github.com/pftf/RPi4/issues/115

GraphicsConsoleDxe defaults the ConOut Mode.CursorVisible to TRUE.
However, the driver never draws the cursor during init. This results
in the first call to disable the cursor (using ConOut->EnableCursor(FALSE))
to actually draw the cursor on the screen, as the logic in FlushCursor
depends on the Mode.CursorVisible state to determine if it should draw or
erase the cursor.

Fix by changing the default CursorVisible in this driver to FALSE.

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3126

1. If use PeiDxeDebugLibReportStatusCode as DebugLib, then some logs
after ExitBootService() will be lost.
2. The root cause:
2.1 The original code will register an unregister function
of gEfiEventExitBootServicesGuid, this unregister function will call
EFI_RSC_HANDLER_PROTOCOL->Unregister and does not support log through
serial port.
2.2 And some other drivers also register call back funtions of
gEfiEventExitBootServicesGuid.
2.3 Then after the unregister function is called, other call back
functions can't out log if them use RSC as DebugLib.
3. The DxeMain will report status code EFI_SW_BS_PC_EXIT_BOOT_SERVICES
after notify all the call back functions of
gEfiEventExitBootServicesGuid.
4. Solution: the StatusCodeHandlerRuntimeDxe.c will not register an
unregister function of gEfiEventExitBootServicesGuid, but unregister it
after receive the status code of EFI_SW_BS_PC_EXIT_BOOT_SERVICES.

The ECC tool crashes if a C file has an incorrect file header
format.

The file ArmPkg\Library\ArmMmuLib\AArch64\ArmMmuPeiLibConstructor.c
has a file header in the incorrect format. It uses # to mark the
header comments instead of enclosing the file header in /* */. This
may have been a result of an INF file header being copied to a C
file.

A separate patch fixes the C file but ECC tool should
not crash if a file with an incorrect header is found.

Therefore, update the ECC tool to prevent it from crashing if an
incorrect file header is found. With this change the ECC tool will
report the incorrect header issue without crashing.

Laszlo Ersek c3f76ef89d OvmfPkg/VirtioFsDxe: add helper for composing rename/move destination path
The EFI_FILE_PROTOCOL.SetInfo() member is somewhat under-specified; one of
its modes of operation is renaming/moving the file.

In order to create the destination pathname in canonical format, 2*2=4
cases have to be considered. For the sake of discussion, assume the
current canonical pathname of a VIRTIO_FS_FILE is "/home/user/f1.txt".
Then, consider the following rename/move requests from
EFI_FILE_PROTOCOL.SetInfo():

  Destination requested  Destination  Move into   Destination in
  by SetInfo()           relative?    directory?  canonical format
  ---------------------  -----------  ----------  -----------------------
  L"\\dir\\f2.txt"       no           no          "/dir/f2.txt"
  L"\\dir\\"             no           yes         "/dir/f1.txt"
  L"dir\\f2.txt"         yes          no          "/home/user/dir/f2.txt"
  L"dir\\"               yes          yes         "/home/user/dir/f1.txt"

Add the VirtioFsComposeRenameDestination() function, for composing the
last column from the current canonical pathname and the SetInfo() input.

The function works on the following principles:

- The prefix of the destination path is "/", if the SetInfo() rename
  request is absolute.

  Otherwise, the dest prefix is the "current directory" (the most specific
  parent directory) of the original pathname (in the above example,
  "/home/user").

- The suffix of the destination path is precisely the SetInfo() request
  string, if the "move into directory" convenience format -- the trailing
  backslash -- is not used. (In the above example, L"\\dir\\f2.txt" and
  L"dir\\f2.txt".)

  Otherwise, the suffix is the SetInfo() request, plus the original
  basename (in the above example, L"\\dir\\f1.txt" and L"dir\\f1.txt").

- The complete destination is created by fusing the dest prefix and the
  dest suffix, using the VirtioFsAppendPath() function.

Laszlo Ersek c9f473df33 OvmfPkg/VirtioFsDxe: handle the volume label in EFI_FILE_PROTOCOL.SetInfo
The least complicated third of EFI_FILE_PROTOCOL.SetInfo() is to handle
the EFI_FILE_SYSTEM_INFO and EFI_FILE_SYSTEM_VOLUME_LABEL setting
requests. Both of those can only change the volume label -- which the
Virtio Filesystem device does not support.

Verify the input for well-formedness, and report success only if the
volume label is being set to its current value.

Laszlo Ersek b845de89d0 OvmfPkg/VirtioFsDxe: add EFI_FILE_INFO cache fields to VIRTIO_FS_FILE
For reading through a directory stream with tolerable performance, we'll
have to call FUSE_READDIRPLUS each time with such a buffer that can
deliver a good number of variable size records
(VIRTIO_FS_FUSE_DIRENTPLUS_RESPONSE elements). Every time we'll do that,
we'll turn the whole bunch into an array of EFI_FILE_INFOs immediately.
EFI_FILE_PROTOCOL.Read() invocations (on directories) will be served from
this EFI_FILE_INFO cache.

Add the fields for the EFI_FILE_INFO cache to VIRTIO_FS_FILE:
- initialize them in Open() and OpenVolume(),
- release the cache in Close() and Delete(),
- also release the cache when the directory is rewound, in SetPosition().

Introduce the VirtioFsFuseDirentPlusToEfiFileInfo() function, for
converting the VIRTIO_FS_FUSE_DIRENTPLUS_RESPONSE filename byte array to
EFI_FILE_INFO.

This new function updates those EFI_FILE_INFO fields (Size, FileName) that
the earlier helper function VirtioFsFuseAttrToEfiFileInfo() does not set.

Both functions together will be able to fill in EFI_FILE_INFO completely,
from FUSE_READDIRPLUS.
