Subject: Re: [PATCH] [MdePkg ] New Debug Message Levels
Date: Wed, 21 Sep 2016 06:10:11 +0000	[thread overview]
Message-ID: <E92EE9817A31E24EB0585FDF735412F56481A4B9@ORSMSX113.amr.corp.intel.com> (raw)
In-Reply-To: <9333E191E0D52B4999CE63A99BA663A00270FEF3B8@atlms1.us.megatrends.com>

Felix,

Thanks for the quick update.

Quick question on usage model.  Do you expect to be able to mix 
an I/O subsystem bit with ERROR, WARN, INFO, or VERBOSE bits?

Unfortunately, I do not think the current definition and implementation
of the DebugLib instances support this type mixing with a result a
developer may expect.

Can you summarize or provide some example use cases for these new bits?

Thanks,

Mike
