Subject: [PATCH 0/2] ExtPkg Updates
Date: Thu, 9 Sep 2021 20:40:59 +0000	[thread overview]
Message-ID: <cover.1631219610.git.jbrasen@nvidia.com> (raw)

I have been using the new Ext4Pkg and been pretty successful and it is solving a use case we had.

Had a couple updates to propose

1. Changed the implementation of the binding protocol to both check if the driver is already bound
to the partition as well as added a really quick check to validate the magic value in supported.
This improves performance when you have a large number of non-ext4 partitions on the system.

2. As we are planning on using this for boot support we want to support unclean filesystem states in
case the user doesn't reset cleanly. I added a check if the recovery journal is present and if so treat
the filesystem as read-only (I know the driver is only RO at this point, but figured if you added write
support prior to recovery journal support we would want that). With this everything seems to work great.
I can add this under a FeaturePcd if desired as well.
