I'm not sure about all that. Two points: * Why would we need separate subdirectories within the bifurcated driver directory? The *only* thing that is different between an implementation of ixgbe and i40e to use the bifurcated driver infrastructure is the code to map between NIC descriptors and rte_mbufs. All the other code would be identical as far as I can work out. So the only two routines that differ are going to be the rx_burst and tx_burst functions. So why not just pull in those two specific functions (or sets of functions) from their respective drivers, and keep the rest of the codebase common? It's surely simpler than having the ixgbe driver having to be aware of whether it's operating in bifurcated mode or uio/vfio/nic_uio mode, to check what operations are supported or not. * It's not really an inter-library dependency - or at least not a hugely problematic one to my mind. With my proposal there is no need for the ixgbe or i40e drivers to be compiled up for the bifurcated driver to work with them. It simply makes use of the rx and tx code functions to do the mapping from descriptors to mbufs. While there will be a dependency on those functions, the nice thing is that those functions are already standardized by the ethdev API, so we don't need to worry about internal changes inside the drivers changing the APIs of those functions. /Bruce > > > My thinking is that the bifurcated driver is so significantly different in > > the way it works, and the limits on it's functionality e.g. no direct filter > > support or queue management, that it's best kept completely separate and > > only > > "borrow" the needed descriptor read/write functions from the other drivers > > as is > > needed. > > > > Just my 2c.

I'd prefer if all > material for the bifurcated driver be kept within the librte_pmd_bifurc > directory. [Liang, Cunming] I haven't a librte_pmd_bifurc library. So far the purpose of librte_bifurc is for device scan, not used as a pmd. During driver probe, depend on device id, it asks for correct pmd from 'librte_pmd_ixgbe, librte_pmd_i40e'. > Is it possible to leave ixgbe largely unmodified and simply have the new > bifurcated driver pull in the needed ixgbe (and later i40e) functions at > compile time i.e. refer from one Makefile to the sources in the other > driver's directory? [Liang, Cunming] Nice point. If we have single directory gathering all direct ring access. e.g. We have aka "librte_pmd_bifurc", inside it, we'll have bifurc_ixgbe, bifurc_i40e, ... Each of them still depend on other libraries like librte_pmd_ixgbe/librte_pmd_i40e. We may remove the internal dependence inside one pmd driver, but between libraries we add more. > My thinking is that the bifurcated driver is so significantly different in > the way it works, and the limits on it's functionality e.g. no direct filter > support or queue management, that it's best kept completely separate and only > "borrow" the needed descriptor read/write functions from the other drivers as > is > needed. > > Just my 2c.

I'd prefer if all material for the bifurcated driver be kept within the librte_pmd_bifurc directory. Is it possible to leave ixgbe largely unmodified and simply have the new bifurcated driver pull in the needed ixgbe (and later i40e) functions at compile time i.e. refer from one Makefile to the sources in the other driver's directory? My thinking is that the bifurcated driver is so significantly different in the way it works, and the limits on it's functionality e.g. no direct filter support or queue management, that it's best kept completely separate and only "borrow" the needed descriptor read/write functions from the other drivers as is needed. Just my 2c. I'm curious as to what others think. /Bruce > diff --git a/lib/librte_pmd_ixgbe/Makefile b/lib/librte_pmd_ixgbe/Makefile > index 3588047..6867f17 100644 > --- a/lib/librte_pmd_ixgbe/Makefile > +++ b/lib/librte_pmd_ixgbe/Makefile > @@ -37,7 +37,7 @@ include $(RTE_SDK)/mk/rte.vars.mk > LIB = librte_pmd_ixgbe.a > > CFLAGS += -O3 > -CFLAGS += $(WERROR_FLAGS) > +CFLAGS += $(WERROR_FLAGS) -Wno-cast-qual > > ifeq ($(CC), icc) > # > @@ -108,10 +108,21 @@ SRCS-$(CONFIG_RTE_LIBRTE_IXGBE_PMD) += ixgbe_bypass.c > SRCS-$(CONFIG_RTE_LIBRTE_IXGBE_PMD) += ixgbe_82599_bypass.c > endif > > +ifeq ($(CONFIG_RTE_LIBRTE_BIFURC),y) > +ifeq ($(CONFIG_RTE_EXEC_ENV_LINUXAPP),y) > +SRCS-$(CONFIG_RTE_LIBRTE_IXGBE_PMD) += ixgbe_bifurcate.c > +endif > +endif > > # this lib depends upon: > DEPDIRS-$(CONFIG_RTE_LIBRTE_IXGBE_PMD) += lib/librte_eal lib/librte_ether > DEPDIRS-$(CONFIG_RTE_LIBRTE_IXGBE_PMD) += lib/librte_mempool lib/librte_mbuf > DEPDIRS-$(CONFIG_RTE_LIBRTE_IXGBE_PMD) += lib/librte_net lib/librte_malloc > +ifeq ($(CONFIG_RTE_LIBRTE_BIFURC),y) > +ifeq ($(CONFIG_RTE_EXEC_ENV_LINUXAPP),y) > +DEPDIRS-$(CONFIG_RTE_LIBRTE_IXGBE_PMD) += lib/librte_bifurc > +endif > +endif > + > > include $(RTE_SDK)/mk/rte.lib.mk > diff --git a/lib/librte_pmd_ixgbe/ixgbe_bifurcate.c > b/lib/librte_pmd_ixgbe/ixgbe_bifurcate.c > new file mode 100644 > index 000..84c445a > --- /dev/null > +++ b/lib/librte_pmd_ixgbe/ixgbe_bifurcate.c > @@ -0,0 +1,303 @@ > +/*- > + * BSD LICENSE > + * > + * Copyright(c) 2010-2014 Intel Corporation.
