Subject: firmware_loader: Log direct loading failures as info for d-i
Date: Thu, 30 May 2024 13:14:32 +0100
Forwarded: not-needed
On an installed Debian system, firmware packages will normally be
installed automatically based on a mapping of device IDs to firmware.
Within the Debian installer this has not yet happened and we need a
way to detect missing firmware.
Although many/most drivers log firmware loading failures, they do so
using many different formats. This adds a single log message to the
firmware loader, which the installer's hw-detect package will look
for. The log level is set to "info" because some failures are
expected and we do not want to confuse users with bogus error messages
(like in bug #966218).
NOTE: The log message format must not be changed without coordinating
this with the check-missing-firmware.sh in hw-detect.
