Subject: [dpdk-dev] [ [PATCH v2] 00/13] Add virtio support in arm/arm64
Date: Mon, 14 Dec 2015 18:30:19 +0530 [thread overview]
Message-ID: <1450098032-21198-1-git-send-email-sshukla@mvista.com> (raw)
This patch set add basic infrastrucure to run virtio-net-pci pmd driver for
arm64/arm. Tested on ThunderX platfrom. Verified for existing dpdk(s) test
applications like:
- ovs-dpdk-vhost-user: across the VM's, for the use-cases like guest2guest and
Host2Guest
- testpmd application: Tested for max virtio-net-pci interface currently
supported in kernel i.e. 31 interface.
Builds successfully for armv7/v8/thunderX and x86_64/i686 platforms. Made sure
that patch changes donot break for x86_64 case. Done similar tests for x86_64
too.
Patch History:
v2:
- Removed ifdef arm.. clutter from igb_uio / virtio_ethedev files
- Introduced rte_io.h header file in generic/ and arch specifics i.e.. for
armv7 --> rte_io_32.h, for armv8 --> rte_io_64.h.
- Removed RTE_ARCH_X86 ifdef clutter too and added rte_io.h header which nothing
but wraps sys/io.h for x86_64 and i686
- Moved all the RTE_ARCH_ARM/64 dependancy for igb_uio case to separate header
file named igbuio_ioport_misc.h. Now igb_uio.c will call only three function
- igbuio_iomap
- igbuio_ioport_register
- igbuio_ioport_unregister
- Moved ARM/64 specific definition to include/exec-env/rte_virt_ioport.h header
- Included virtio_ioport.c/h; has all private and public api required to map
iopci bar for non-x86 arch. Tested on thunderX and x86_64 both.
Private api includes:
- virtio_map_ioport
- virtio_set_ioport_addr
Public api includes:
- virtio_ioport_init
- virtio_ioport_unmap
- Last patch is the miscllanious format specifier fix identifid for 64bit case
during regression.
v1:
- First patch adds RTE_VIRTIO_INC_VECTOR config, much needed for archs like
arm/arm64 as they don't support vectored implementation, also wont able to
build.
- Second patch is in-general fix for i686.
- Third patch is to emulate x86-style of {in,out}[b,w,l] api support for armv7/v8.
As virtio-net-pci pmd driver uses those apis for port rd/wr {b,w,l}
- Fourth patch to enable VIRTIO_PMD feature in armv7/v8/thunderX config.
- Fifth patch to disable iopl syscall, As arm/arm64 linux kernel doesn't support
them.
- Sixth patch introduces ioport memdevice called /dev/igb_ioport by which virtio
pmd driver could able to rd/wr PCI_IOBAR.
{applicable for arm/arm64 only, tested for arm64 as of now}
Santosh Shukla (13):
virtio: Introduce config RTE_VIRTIO_INC_VECTOR
