Hi all, I find a patch about vdpa driver of dpdk --vdpa/mlx5: handle hardware error I want to know ,what is scenario of this patch? Our enviroment is dpdk19.11 +some patches from Mellanox ,and Connect6 DX. We tested vdpa by taking a long time of iperf between two VMs , but found that VMs cannot send any package. Maybe we should apply this patch.
About this path When hardware error happens, vdpa didn't get such information and leave driver in silent: working state but no response. This patch subscribes firmware virtq error event and try to recover max 3 times in 3 seconds, stop virtq if max retry number reached. When error happens, PMD log in warning level. If failed to recover, outputs error log. Query virtq statistics to get error counters report. ------------------------------------------------------------------------------------------------------------------------------------- 本邮件及其附件含有新华三集团的保密信息，仅限于发送给上面地址中列出 的个人或群组。禁止任何其他人以任何形式使用（包括但不限于全部或部分地泄露、复制、 或散发）本邮件中的信息。如果您错收了本邮件，请您立即电话或邮件通知发件人并删除本 邮件！ This e-mail and its attachments contain confidential information from New H3C, which is intended only for the person or entity whose address is listed above.
