DPDK 21.05 Huawei hns3 Roadmap
by oulijun 01 Mar '21

01 Mar '21

Hi， Following are the work items of hns3 PMD planned for 21.05, Some features are delayed to the current releases. New features: 【1】 Add PTP(Precise Time Protocol) support 【2】 Add query optical module info by API 【3】 Support LSC(Link Status Changed) event The LSC reporting function of the PF has been completed in 21.02. This task involves the LSC reporting function of the VF and the LSC capability setting through the rte_pci_drvier.drv_flags. 【4】 Implement tx_done_cleanup API 【5】 Implement Rx/Tx descriptor status API 【6】 Support runtime config for selecting Tx/Rx function 【7】 Kunpeng930 support electrical port 【8】 Kunpeng930 support flow control auto-negotiation 【9】 Kunpeng930 support for simple BD mode for Tx checksum 【10】 Kunpeng930 Support link speed configuration for PF 【11】 Support new RAS mechanism for Kunpeng930 Enhanced functionality: 【11】 Extend the DPDK stats 【12】 Extend the DPDK rte_dev_get_regs API implementation for query more common register information 【13】 Extend outer UDP cksum offload 【14】 Rx receive function optimization for improving performance support rxd advanced layout support checksum simple computing and ptype optimization 【15】 Support push mode for Tx queue bonding function：【16】 some bonding modes support prepare API testpmd updates：【17】 testpmd support multi-process test Others：【18】 Extend for hns3 document Thanks Lijun Ou

[PATCH v1] drm/nouveau/device: append a NUL-terminated character for the string which filled by strncpy()
by Luo Jiaxing 27 Feb '21

27 Feb '21

Following warning is found when using W=1 to build kernel: In function ‘nvkm_udevice_info’, inlined from ‘nvkm_udevice_mthd’ at drivers/gpu/drm/nouveau/nvkm/engine/device/user.c:195:10: drivers/gpu/drm/nouveau/nvkm/engine/device/user.c:164:2: warning: ‘strncpy’ specified bound 16 equals destination size [-Wstringop-truncation] 164 | strncpy(args->v0.chip, device->chip->name, sizeof(args->v0.chip)); drivers/gpu/drm/nouveau/nvkm/engine/device/user.c:165:2: warning: ‘strncpy’ specified bound 64 equals destination size [-Wstringop-truncation] 165 | strncpy(args->v0.name, device->name, sizeof(args->v0.name)); The reason of this warning is strncpy() does not guarantee that the destination buffer will be NUL terminated. If the length of source string is bigger than number we set by third input parameter, only first [number] of characters is copied to the destination, and no NUL-terminated is automatically added. There are some potential risks.
