Three items in configuration files are needed to support them at compile time. Those three items are, - CONFIG_RTE_PCI_CONFIG - CONFIG_RTE_PCI_EXTENDED_TAG - CONFIG_RTE_PCI_MAX_READ_REQUEST_SIZE Signed-off-by: Helin Zhang <helin.zhang@intel.com> Signed-off-by: Jing Chen <jing.d.chen@intel.com> Acked-by: Cunming Liang <cunming.liang@intel.com> Acked-by: Jijiang Liu <jijiang.liu@intel.com> Acked-by: Jingjing Wu <jingjing.wu@intel.com> Tested-by: Waterman Cao <waterman.cao@intel.com> --- config/common_linuxapp | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/config/common_linuxapp b/config/common_linuxapp index da20011..a020451 100644 --- a/config/common_linuxapp +++ b/config/common_linuxapp @@ -125,6 +125,16 @@ CONFIG_RTE_EAL_ALLOW_INV_SOCKET_ID=n CONFIG_RTE_EAL_ALWAYS_PANIC_ON_ERROR=n # +# Special configurations in PCI Config Space for high performance +# CONFIG_RTE_PCI_CONFIG is the compile switch for two features below +# CONFIG_RTE_PCI_EXTENDED_TAG can be "on", "off" +# CONFIG_RTE_PCI_MAX_READ_REQUEST_SIZE can be 128, 256, 512, 1024, 2048, 4096 +# +CONFIG_RTE_PCI_CONFIG=n +CONFIG_RTE_PCI_EXTENDED_TAG="" +CONFIG_RTE_PCI_MAX_READ_REQUEST_SIZE=0 + +# # Compile Environment Abstraction Layer for linux # CONFIG_RTE_LIBRTE_EAL_LINUXAPP=y -- 1.8.1.4
