Subject: [PATCH v2 1/2] bbdev: add new function to dump debug information
Date: Thu, 29 Aug 2024 13:06:23 -0700	[thread overview]
Message-ID: <20240829200624.38551-2-nicolas.chautru@intel.com> (raw)
In-Reply-To: <20240829200624.38551-1-nicolas.chautru@intel.com>

This provides a new API to dump more debug information
related to the status on a given bbdev queue.
Some of this information is visible at bbdev level.
This also provides a new option dev op, to print more
information at the lower PMD level.
This helps user to troubleshoot issues related to
previous operations provided into a queue causing
possible hard-to-debug negative scenarios.
