From: Jerin Jacob Date: Fri, 9 Jun 2017 08:37:28 +0000 (+0530) Subject: eventdev: make PCI probe and remove functions optional X-Git-Tag: spdx-start~2972 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=9a8269d56942c5a59b4358b19b0dc6392b7b6bf9;p=dpdk.git eventdev: make PCI probe and remove functions optional Made libeventdev library independent of PCI bus by moving pci pmd specific function to rte_eventdev_pmd_pci.h header file. Eventdev PCI PMD can include that for generic eventdev PCI probe and remove function enablement.
