Subject: [edk2-devel] [PATCH v1 1/1] MdeModulePkg: Warn if out of flash space when writing variables
Date: Mon, 4 Mar 2024 16:18:03 +0100 [thread overview]
Message-ID: <20240304151805.129004-2-osteffen@redhat.com> (raw)
In-Reply-To: <20240304151805.129004-1-osteffen@redhat.com>
Emit a DEBUG_WARN message if there is not enough flash space left to
write/update a variable. This condition is currently not logged
appropriately in all cases, given that full variable store can easily
render the system unbootable.
This new message helps identifying this condition.
