Subject: [dpdk-dev] [PATCH v9 06/23] event/dlb2: add eventdev probe
Date: Sat, 31 Oct 2020 12:26:04 -0500 [thread overview]
Message-ID: <1604165181-19929-7-git-send-email-timothy.mcdaniel@intel.com> (raw)
In-Reply-To: <1604165181-19929-1-git-send-email-timothy.mcdaniel@intel.com>
Add the eventdev portion of probe, and parse command line
options, but do not initialize hardware.
Changes since v2 patch-set probe:
Primary and secondary probe-time init has been removed, and
will be introduced in subsequent patches contained in
the v3 patch-set.
Hardware init has been moved to a subsequent patch in order to
minimize the patch size. The files dlb2/pf/dlb2_pf.c and
dlb2/pf/dlb_main.c include stubs of hardware init functions,
and these will be replaced with the real versions when the
hardware layer is committed.
Initialization of the flexible interface layer has been moved to
a subsequent patch in order to minimize patch size.
