Subject: [dpdk-dev] [PATCH v4 1/9] eal: move librte_malloc to eal/common
Date: Thu, 25 Jun 2015 15:05:47 +0100 [thread overview]
Message-ID: <1435241155-23684-2-git-send-email-sergio.gonzalez.monroy@intel.com> (raw)
In-Reply-To: <1435241155-23684-1-git-send-email-sergio.gonzalez.monroy@intel.com>
Move malloc inside eal.
Create a dummy malloc library to avoid breaking applications that have
librte_malloc in their DT_NEEDED entries.
This is the first step towards using malloc to allocate memory directly
from memsegs. Thus, memzones would allocate memory through malloc,
allowing to free memzones.
