Hi,
This patchset contains a read-only filesystem driver for UDF volumes found on
discs.
I've been testing the driver with OVMF and Microsoft Windows 7/8.1 OS images.
It can open, read and list files and directories on UDF filesystems
successfully. If the working directory contains a lot of entries, the listing
goes OK and fast -- however, if I cd /path/to/it and (TAB), it takes longer to
show the first directory entry. This performance issue might be worked around
by caching directory entries from open directories in UdfOpen() function -- that
doesn't affect functionality at all.
Its development was all under MdeModulePkg/Universal/Disk - which doesn't seem
right to me. So, I'm wondering if it would be possible to add a new package
called "FileSystemPkg" and put all filesystem drivers into it.
Since I wrote this driver only in my free time (which is usually short), the
write support is a future project of mine :-)
There is a public branch which contains all these patches and it's rebased
against master from mainline and can be clone at:
git://git.zytor.com/users/pcacjr/edk2.git (branch: for-upstream)
Thanks,
