Subject: [dpdk-dev] [PATCH 0/4] Enhance CPU flag support
Date: Wed, 29 May 2019 16:41:28 +0100 [thread overview]
Message-ID: <20190529154132.49955-1-bruce.richardson@intel.com> (raw)
Currently in DPDK, any checks for the presence or absense of specific
CPU flags has to be enclosed in #ifdef blocks, since the flags are
conditionally defined per architecture as enums. This set attempts to
improve this situation by allowing the flags to be queried as strings,
with a CPU architecture type also specified. One new public API is
provided for this. [Other APIs used by that are internal for now, but
have an rte_ prefix in case we want to expose them publically later]
To test out this new functionality the crc code in the net library is
updated to use this, demonstrating how the code can be simplified and
the use of #ifdef's reduced.
Bruce Richardson (4):
build: fix quoting on RTE_ARCH string value
config/arm: fix missing define for arm platforms
eal: allow checking CPU flags by name
net: replace ifdefs with runtime branches
