Convert the line endings stored for all text files in the repository to LF. The majority previously used DOS-style CRLF line endings. Add a .gitattributes file to enforce this and treat certain extensions as never being text files. Update PatchCheck.py to insist on LF line endings rather than CRLF. However, its other checks fail on this commit due to lots of pre-existing complaints that it only notices because the line endings have changed. Silicon/QemuSocPkg/FspBin/Patches/0001-Build-QEMU-FSP-2.0-binaries.patch needs to be treated as binary since it contains a mixture of line endings. This change has implications depending on the client platform you are using the repository from: * Windows The usual configuration for Git on Windows means that text files will be checked out to the work tree with DOS-style CRLF line endings. If that's not the case then you can configure Git to do so for the entire machine with: git config --global core.autocrlf true or for just the repository with: git config core.autocrlf true Line endings will be normalised to LF when they are committed to the repository. If you commit a text file with only LF line endings then it will be converted to CRLF line endings in your work tree. * Linux, MacOS and other Unices The usual configuration for Git on such platforms is to check files out of the repository with LF line endings. This is probably the right thing for you. In the unlikely even that you are using Git on Unix but editing or compiling on Windows for some reason then you may need to tweak your configuration to force the use of CRLF line endings as described above. * General For more information see https://docs.github.com/en/get-started/getting-started-with-git/configuring-git-to-handle-line-endings .

/**
|
|
A directory consists of some number of blocks of e2fs_bsize bytes.
|
|
|
|
Each block contains some number of directory entry
|
|
structures, which are of variable length. Each directory entry has
|
|
a struct direct at the front of it, containing its inode number,
|
|
the length of the entry, and the length of the name contained in
|
|
the entry. These are followed by the name padded to a 4 byte boundary
|
|
with null bytes. All names are guaranteed null terminated.
|
|
The maximum length of a name in a directory is EXT2FS_MAXNAMLEN.
|
|
|
|
The macro EXT2FS_DIRSIZ(fmt, dp) gives the amount of space required to
|
|
represent a directory entry. Free space in a directory is represented by
|
|
entries which have dp->Ext2DirectRecLen > DIRSIZ(fmt, dp). All d2fs_bsize bytes
|
|
in a directory block are claimed by the directory entries. This
|
|
usually results in the last entry in a directory having a large
|
|
dp->Ext2DirectRecLen. When entries are deleted from a directory, the
|
|
space is returned to the previous entry in the same directory
|
|
block by increasing its dp->Ext2DirectRecLen. If the first entry of
|
|
a directory block is free, then its dp->Ext2DirectInodeNumber is set to 0.
|
|
Entries other than the first in a directory do not normally have
|
|
dp->Ext2DirectInodeNumber set to 0.
|
|
Ext2 rev 0 has a 16 bits Ext2DirectNameLen. For Ext2 vev 1 this has been split
|
|
into a 8 bits Ext2DirectNameLen and 8 bits Ext2DirectType (looks like ffs, isnt't it ? :)
|
|
It's safe to use this for rev 0 as well because all ext2 are little-endian.
