This is a follow-up of an idea presented at Dublin during the "hotplug talk".
The idea is to ease probing of range of ports attached to the same rte_device. I becomes possible to allow probing again the same device but with a bigger range of ports in the devargs. Instead of adding a parameter to the hotplug functions, as in the RFC, the check of an already probed device is moved to the bus and enabled PMDs. It gives flexibility to drivers for managing range of ports. Changes in v5 - after Andrew's review: - remove driver name usage in mlx5/szedata2 probing and crypto/compress logs - update DMA ring names in bnx2x, cxgbe, vmxnet3 and testpmd lookup Changes in v4 - after Andrew's review: - remove access to rte_device.driver during probing (patch 1) Changes in v3 - after Declan's review: - return error in all buses but PCI - add a PCI driver flag to enable feature per driver - return -EEXIST if probing again is not supported Thomas Monjalon (7): net/mlx5: remove useless driver name comparison ethdev: rename memzones allocated for DMA cryptodev: remove driver name from logs compressdev: remove driver name from logs drivers/bus: move driver assignment to end of probing eal: add function to query device status eal: allow probing a device again app/test-pmd/config.c | 4 +-- drivers/bus/dpaa/dpaa_bus.c | 3 ++ drivers/bus/fslmc/fslmc_bus.c | 3 ++ drivers/bus/ifpga/ifpga_bus.c | 21 +++++------ drivers/bus/pci/pci_common.c | 38 ++++++++++++-------- drivers/bus/pci/rte_bus_pci.h | 6 ++-- drivers/bus/vdev/vdev.c | 12 ++++--- drivers/bus/vmbus/vmbus_common.c | 5 +-- drivers/net/bnx2x/bnx2x_rxtx.c | 15 ++------ drivers/net/cxgbe/sge.c | 24 ++++++------- drivers/net/i40e/i40e_vf_representor.c | 3 -- drivers/net/mlx4/mlx4.c | 1 - drivers/net/mlx5/mlx5.c | 1 - drivers/net/mlx5/mlx5_ethdev.c | 5 +-- drivers/net/szedata2/rte_eth_szedata2.c | 6 ++-- drivers/net/vmxnet3/vmxnet3_ethdev.c | 4 +-- lib/librte_compressdev/rte_compressdev_pmd.c | 23 +++++------- lib/librte_cryptodev/rte_cryptodev_pmd.c | 23 +++++------- lib/librte_eal/common/eal_common_dev.c | 14 +++++--- lib/librte_eal/common/include/rte_dev.h | 18 ++++++++-- lib/librte_eal/rte_eal_version.map | 1 + lib/librte_ethdev/rte_ethdev.c | 5 ++- 22 files changed, 121 insertions(+), 114 deletions(-) -- 2.19.0
