Package: raspi-firmware Version: 1.20201022-1 Severity: normal X-Debbugs-CC: lu...@debian.org
Dear Debian raspi-firmware maintainers, Linux 5.10 kernel's vc4.ko starts partial support of RPi 2/3/4 VideoCore 4 GPU, and it enables 4K HDMI output, which is very welcome. But in some situation, screen output is garbled as reported at http://lists.infradead.org/pipermail/linux-rpi-kernel/2020-November/007894.html The above symptom can be fixed by adding disable_fw_kms_setup=1 as reported at http://lists.infradead.org/pipermail/linux-rpi-kernel/2020-November/007900.html I do not think this is a bug in raspi-firmware, but config.txt is handled by raspi-firmware, please consider to add disable_fw_kms_setup=1. Best regards, Ryutaroh Matsumoto
