Subject: [dpdk-dev] [PATCH v2] mk: parallelize make config
Date: Mon, 30 Jan 2017 10:21:15 +0000 [thread overview]
Message-ID: <20170130102115.20975-1-ferruh.yigit@intel.com> (raw)
In-Reply-To: <20170122015034.19824-1-ferruh.yigit@intel.com>
make config dependency resolving was always running serial,
parallelize it for better performance.
$ time make T=x86_64-native-linuxapp-gcc config
real 0m12.633s
$ time make -j8 T=x86_64-native-linuxapp-gcc config
real 0m1.826s
When config creation done under a single make target, using a for loop,
make has no control on the action, and it needs to run as implemented in
the rule. But if for loop converted into multiple targets, make can
detect independent targets and run them parallel based on -j parameter.
