Subject: [dpdk-dev] [PATCH v2 0/4] rework ioport access for virtio
Date: Sun, 7 Feb 2016 08:48:33 +0100 [thread overview]
Message-ID: <1454831317-4542-1-git-send-email-david.marchand@6wind.com> (raw)
In-Reply-To: <1454694945-18040-1-git-send-email-david.marchand@6wind.com>
Introduce a new pci ioport api in eal to mask all arch / kernel driver
specifics.
- rte_eal_pci_ioport_map is responsible for initialising an rte_pci_ioport
object that is used in subsequent calls, this function must be tweaked per
architecture and per kernel driver,
- rte_eal_pci_ioport_read / rte_eal_pci_ioport_write uses a rte_pci_ioport
object to read / write those resources,
- rte_eal_pci_ioport_unmap releases resources used by a rte_pci_ioport
object if necessary.
There is still some more work to ensure intr handle are properly initialized
and released when used in conjonction with rte_eal_map_device() api calls.
BSD code has been neither run nor compiled, please can someone confirm I did
not break too much stuff ?
virtio legacy code has been updated accordingly.
With this, virtio code should be ready for other archs now.
So in the end, all that is missing on linux is some vfio update for support
of all architectures that have vfio.
Changes since v1:
- dropped rte_ioport and removed the arch headers, if performance is an
issue, we will see how to enhance this in later patches
