Subject: [dpdk-dev] [PATCH v2] usertools/devbind: fix binding for built-in 1kernel drivers
Date: Wed, 18 Nov 2020 10:58:54 +0800
Message-ID: <20201118025854.13455-1-yongxin.liu@windriver.com> (raw)

In commit 681a67288655 ("usertools: check if module is loaded before
binding"), script will exit if no driver is found in /sys/module/.

However, for built-in kernel driver, /sys/module/MODULENAME only
shows up if it has a version or at least one parameter. Take ixgbe
for example, after kernel commit 34a2a3b83e2c ("net/intel: remove
driver versions from Intel drivers"), and if ixgbe is built directly
into kernel, there is no ixgbe folder in /sys/module. So the devbind
script should not exit.
