Subject: [REGRESSION] "of: Fix premature bootconsole disable with 'stdout-path'" breaks console on tty0
Date: Mon, 16 Mar 2015 17:31:00 +0100 [thread overview]
Message-ID: <55070544.9010908@redhat.com> (raw)
Hi All,
While updating my local working tree to 4.0-rc4 this morning I noticed that I no longer
get console / kernel messages output on the hdmi output of my ARM board / on tty0
This is caused by:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/of?id=2fa645cb2703d9b3786d850db815414dfeefa51d
Reverting this commit fixes this for me.
What is happening here is that the "add_preferred_console("stdout-path", 0, NULL);"
happens before the tty0 registers stopping tty0 from becoming part of the console list
since there already is a preferred console at that time.
This is an undesirable behavior change caused by the commit in question, on boards
where there is both video output, and a serial console configured through stdout-path
we want to have console output on both as we do not know which of the 2 will actually
be hooked up by the user.
Regards,
Hans
