Hello Quentin,

sorry for being late to the party, but I just tested v2024.10-rc6 and
my console output looks like this now:

This goes on for several screen pages, and clutters the usual output.
I first thought I messed up CONFIG_LOGLEVEL or CONFIG_LOG, but no.
All I had done was setting CONFIG_DM_WARN …

Prior to that, seeing the debug() messages required to enable DM_DEBUG
which defines DEBUG (and then _DEBUG) which in turn makes failing
assert() calls reset U-Boot which isn't necessarily what is desired.

Instead, let's migrate to dm_warn which is using log_debug when unset or
log_warn when set.

While at it, reword the DM_DEBUG symbol in Kconfig to explain what it
now actually does.

CONFIG_DM_WARN currently reads like this:

     Enable this to see warnings related to driver model.

     Warnings may help with debugging, such as when expected devices do
     not bind correctly. If the option is disabled, dm_warn() is compiled
     out - it will do nothing when called.

Instead of just useful warnings, users get debug messages all over the
place now.  Is this actually intended behaviour?  Can this be fixed
before v2024.10 release please?


There are basically less than 3 working days left before v2024.10 is released 
and I'm inclined to say this is annoying rather than a bug, so I am not 
entirely sure this will 1) make it in time if we agree on a fix (needs to 
include review process in those 3 working days) 2) be acceptable for a late 
addition in the release cycle. Let's try though, maybe we can figure something 
out.

This is a bug. Printing this many messages will have a major impact on boot 
times.

A config going from "may print out a few more lines of extra info" to "firehose"
is very surprising to users (as evidenced by Alexander's email).

If you can't figure out which lines to disable, I recommend simply reverting the
patch.
