It is simply a mask used to enable or disable ports in DPDK. For example: If DPDK owns two ports, -p 0x03 means all two ports are enabled. If DPDK owns four ports, -p 0x03 means only port 0 and 1 are enabled, port 2 and 3 are unable to use. If you want to enable all ports, you should use -p 0x0f 0x03 is 0b11, 0x0f is 0b1111 Thanks, Michael > Happy New Year -- > Lyn > > On Wed, Dec 31, 2014 at 10:00 PM, Neil Horman <nhorman at tuxdriver.com> > wrote: > >> On Wed, Dec 31, 2014 at 10:37:45PM -0500, Neil Horman wrote: >>> On Wed, Dec 31, 2014 at 10:50:10AM -0600, Lyn M wrote: >>>> Neil, >>>> When I build DPDK 1.8.0 with the default value >> CONFIG_RTE_BUILD_COMBINE_LIBS=n, >>>> I am able to run the testpmd successfully.
