This series moves the network device simulator in a new module (vdpa_sim_net) and leaves the generic functions in the vdpa_sim core module, allowing the possibility to add new vDPA device simulators.
For now I removed the vdpa-blk simulator patches, since I'm still working on them and debugging the iotlb issues. Thanks to Max that started this work! I took his patches and extended a bit. v1: https://lists.linuxfoundation.org/pipermail/virtualization/2020-November/050677.html v2: https://lists.linuxfoundation.org/pipermail/virtualization/2020-November/051036.html v3: - avoided to remove some headers with structures and functions directly used [Jason] - defined VHOST_IOTLB_UNLIMITED macro in vhost_iotlb.h [Jason] - added set_config callback in vdpasim_dev_attr [Jason] - cleared notify during reset [Jason] Max Gurtovoy (2): vdpa_sim: remove hard-coded virtq count vdpa: split vdpasim to core and net modules Stefano Garzarella (17): vdpa: remove unnecessary 'default n' in Kconfig entries vdpa_sim: remove unnecessary headers inclusion vhost/iotlb: add VHOST_IOTLB_UNLIMITED macro vdpa_sim: remove the limit of IOTLB entries vdpa_sim: rename vdpasim_config_ops variables vdpa_sim: add struct vdpasim_dev_attr for device attributes vdpa_sim: add device id field in vdpasim_dev_attr vdpa_sim: add supported_features field in vdpasim_dev_attr vdpa_sim: add work_fn in vdpasim_dev_attr vdpa_sim: store parsed MAC address in a buffer vdpa_sim: make 'config' generic and usable for any device type vdpa_sim: add get_config callback in vdpasim_dev_attr vdpa_sim: add set_config callback in vdpasim_dev_attr vdpa_sim: set vringh notify callback vdpa_sim: use kvmalloc to allocate vdpasim->buffer vdpa_sim: make vdpasim->buffer size configurable vdpa_sim: split vdpasim_virtqueue's iov field in out_iov and in_iov drivers/vdpa/vdpa_sim/vdpa_sim.h | 105 ++++++++++ include/linux/vhost_iotlb.h | 2 + drivers/vdpa/vdpa_sim/vdpa_sim.c | 301 +++++++-------------------- drivers/vdpa/vdpa_sim/vdpa_sim_net.c | 171 +++++++++++++++ drivers/vhost/iotlb.c | 3 +- drivers/vdpa/Kconfig | 16 +- drivers/vdpa/vdpa_sim/Makefile | 1 + 7 files changed, 368 insertions(+), 231 deletions(-) create mode 100644 drivers/vdpa/vdpa_sim/vdpa_sim.h create mode 100644 drivers/vdpa/vdpa_sim/vdpa_sim_net.c -- 2.26.2 _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
