Subject: [dpdk-dev] [PATCH 4/4] pci: fix ioport support for uio_pci_generic on x86
Date: Tue, 15 Mar 2016 07:29:13 +0100 [thread overview]
Message-ID: <1458023353-22268-5-git-send-email-david.marchand@6wind.com> (raw)
In-Reply-To: <1458023353-22268-1-git-send-email-david.marchand@6wind.com>
uio_pci_generic does not offer the same sysfs helpers as igb_uio.
In this case, ioport number can only be retrieved by parsing /proc/ioports.
Fixes: 756ce64b1ecd ("eal: introduce PCI ioport API")
Reported-by: Mauricio Vásquez <mauricio.vasquezbernal@studenti.polito.it>
