如何通过vid、did查看内核是否原生支持某设备
上面扫出来不兼容的2块板卡为例，查看当前的内核是否支持
- 在openEuler20.03-LTS-sp3上查看：
[root@ecs-cd1c ~]# cat /etc/os-release
NAME=“openEuler”
VERSION=“20.03 (LTS-SP3)”
ID=“openEuler”
VERSION_ID=“20.03”
PRETTY_NAME=“openEuler 20.03 (LTS-SP3)”
ANSI_COLOR=“0;31”
[root@ecs-cd1c ~]# uname -a
Linux ecs-cd1c 4.19.90-2305.4.0.0203.oe1.x86_64 #1 SMP Wed May 31 03:56:13 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
[root@ecs-cd1c ~]# cd /lib/modules/4.19.90-2003.4.0.0036.oe1.x86_64/
[root@ecs-cd1c 4.19.90-2003.4.0.0036.oe1.x86_64]# grep -i -r 14e4 . |grep -i 165f

[root@ecs-cd1c 4.19.90-2003.4.0.0036.oe1.x86_64]# grep -i -r 1000 . |grep -i 005b
./modules.alias:alias pci:v00001000d0000005Bsvsdbcsci* megaraid_sas
有输出表示以上2块版卡，在openEuler20.03-LTS-sp3上是兼容的。
