(while this is probably not technically a fedora rawhide issue,
since i'm trying this on rawhide, i figure this would be the best
place to ask about it.)
i really should know how to do this, but i'm confused about what
happens when i try to configure which "kernel" messages i generate
actually go to the console.
on my rawhide system, my current log level settings are:
# cat /proc/sys/kernel/printk
8 4 1 7
#
for which my long-time understanding is that the first value
represents the value less than which messages of that loglevel will
appear on the system console -- and a value of 8 means all of them.
so having earlier set that first value manually with:
# echo 8 > /proc/sys/kernel/printk
i can now experiment by generating messages in userspace with
variations like:
# echo "<0> level 0" > /dev/kmsg
# echo "<1> level 1" > /dev/kmsg
# echo "<7> level 7" > /dev/kmsg
and so on. now if i follow the contents of dmesg in real time with:
$ dmesg -w
i can indeed see all of these messages adding their brief contents to
the dmesg buffer as i generate them.
*however*, only messages with log level 0 are immediately dumped to
all of the open xterm windows in my graphical session, which i equate
with the system console. any messages with log levels 1 through 7 do
*not* show up that way.
what am i misunderstanding here?
