This series proposes to change this behavior via a new EAL option. -- David Marchand Changes since RFC v2: - went one step further and reworked devargs lookup in buses following Bruce comment (see patch 4 which is cosmetic, and patch 5), - updated device selection helper accordingly and changed API to be device name based, - renamed option, added check on -b presence, updated doc in the last patch, Changes since RFC v1: - reviewed bus probe() and cleaned up NXP drivers, - changed approach following Bruce comment, David Marchand (7): devtools: check packet forwarding in null test bus/fslmc: fix bus cleanup drivers/bus: require probe function for NXP drivers drivers: cleanup devargs lookup in bus scan bus: factorize devargs lookup bus: factorize device selection eal: configure initial device probing app/test/test_eal_flags.c | 63 +++++++++++++++++ devtools/test-null.sh | 10 ++- doc/guides/linux_gsg/eal_args.include.rst | 13 ++++ drivers/bus/auxiliary/auxiliary_common.c | 33 +-------- drivers/bus/auxiliary/bus_auxiliary_driver.h | 2 - drivers/bus/auxiliary/linux/auxiliary.c | 2 +- drivers/bus/auxiliary/private.h | 6 -- drivers/bus/cdx/cdx.c | 34 +--------- drivers/bus/dpaa/dpaa_bus.c | 71 +++++++++----------- drivers/bus/fslmc/fslmc_bus.c | 69 ++++++++----------- drivers/bus/fslmc/fslmc_vfio.c | 22 ++---- drivers/bus/ifpga/bus_ifpga_driver.h | 2 - drivers/bus/ifpga/ifpga_bus.c | 4 +- drivers/bus/pci/bsd/pci.c | 5 +- drivers/bus/pci/linux/pci.c | 2 +- drivers/bus/pci/pci_common.c | 51 ++++---------- drivers/bus/pci/private.h | 11 --- drivers/bus/pci/windows/pci.c | 4 +- drivers/bus/platform/platform.c | 43 +----------- drivers/bus/uacce/uacce.c | 39 +---------- drivers/bus/vdev/vdev.c | 2 +- drivers/bus/vmbus/linux/vmbus_bus.c | 2 +- drivers/bus/vmbus/private.h | 3 - drivers/bus/vmbus/vmbus_common.c | 45 +++---------- drivers/dma/idxd/idxd_bus.c | 18 +---- drivers/raw/ifpga/ifpga_rawdev.c | 2 +- lib/eal/common/eal_common_bus.c | 44 ++++++++++++ lib/eal/common/eal_common_options.c | 10 +++ lib/eal/common/eal_internal_cfg.h | 1 + lib/eal/common/eal_option_list.h | 2 + lib/eal/include/bus_driver.h | 37 ++++++++++ 31 files changed, 288 insertions(+), 364 deletions(-) -- 2.53.0
