Subject: [dpdk-dev] [PATCH v2 0/3] dynamic linking support
Date: Fri, 1 Sep 2017 16:56:59 +0800 [thread overview]
Message-ID: <1504256222-32969-1-git-send-email-xiaoyun.li@intel.com> (raw)
In-Reply-To: <1503626773-184682-1-git-send-email-xiaoyun.li@intel.com>
This patchset dynamically selects functions at run-time based on CPU flags
that current machine supports. This patchset modifies mempcy, memcpy perf
test and x86 EFD, using function pointers and bind them at constructor time.
Then in the cloud environment, users can compiler once for the minimum target
such as 'haswell'(not 'native') and run on different platforms (equal or above
haswell) and can get ISA optimization based on running CPU.
Xiaoyun Li (3):
eal/x86: run-time dispatch over memcpy
app/test: run-time dispatch over memcpy perf test
efd: run-time dispatch over x86 EFD functions
