Subject: [PATCH] efistub: Lower default log level
Date: Tue, 08 Jul 2025 02:30:42 -0500	[thread overview]
Message-ID: <20250708-efi-default-loglevel-v1-1-12b80db5af16@gmail.com> (raw)

From: Aaron Kling <webgeek1234@gmail.com>

Some uefi implementations will write the efistub logs to the display
over a splash image. This is not desirable for debug and info logs, so
lower the default efi log level to exclude them.
