Subject: [dpdk-dev] [PATCH v2 05/32] eal/trace: add internal trace init and fini interface
Date: Thu, 26 Mar 2020 02:45:35 +0530	[thread overview]
Message-ID: <20200325211603.240288-6-jerinj@marvell.com> (raw)
In-Reply-To: <20200325211603.240288-1-jerinj@marvell.com>

From: Jerin Jacob <jerinj@marvell.com>

Define eal_trace_init() and eal_trace_fini() EAL interface
functions that rte_eal_init() and rte_eal_cleanup() function can be
use to initialize and finalize the trace subsystem.
eal_trace_init() function will add the following
functionality if trace is enabled through EAL command line param.

- Test for trace registration failure.
- Test for duplicate trace name registration
- Generate UUID ver 4.
- Create a trace directory
