一、安装命令工具
# yum install pciutils lshw -y
二、获取显示信息
# lspci | grep -E "VGA|NVIDIA" 03:00.0 VGA compatible controller: Matrox Electronics Systems Ltd. Integrated Matrox G200eW3 Graphics Controller (rev 04) 3b:00.0 3D controller: NVIDIA Corporation GA100 [GRID A100 PCIe 40GB] (rev a1) d8:00.0 3D controller: NVIDIA Corporation GA100 [GRID A100 PCIe 40GB] (rev a1)

三、查看驱动信息
# lshw -c video | grep configuration configuration: driver=mgag200 latency=0 maxlatency=32 mingnt=16 configuration: driver=nvidia latency=0 configuration: driver=nvidia latency=0# modinfo nvidia filename: /lib/modules/3.10.0-1160.el7.x86_64/kernel/drivers/video/nvidia.ko firmware: nvidia/470.57.02/gsp.bin alias: char-major-195-* version: 470.57.02 supported: external license: NVIDIA retpoline: Y rhelversion: 7.9 srcversion: 00F9E8DEACC0FB98727C03C alias: pci:v000010DEd*sv*sd*bc03sc02i00* alias: pci:v000010DEd*sv*sd*bc03sc00i00* depends: drm vermagic: 3.10.0-1160.el7.x86_64 SMP mod_unload modversions parm: NvSwitchRegDwords:NvSwitch regkey (charp) parm: NvSwitchBlacklist:NvSwitchBlacklist=uuid[,uuid...] (charp) parm: NVreg_ResmanDebugLevel:int parm: NVreg_RmLogonRC:int parm: NVreg_ModifyDeviceFiles:int parm: NVreg_DeviceFileUID:int parm: NVreg_DeviceFileGID:int parm: NVreg_DeviceFileMode:int parm: NVreg_InitializeSystemMemoryAllocations:int parm: NVreg_UsePageAttributeTable:int parm: NVreg_RegisterForACPIEvents:int parm: NVreg_EnablePCIeGen3:int parm: NVreg_EnableMSI:int parm: NVreg_TCEBypassMode:int parm: NVreg_EnableStreamMemOPs:int parm: NVreg_RestrictProfilingToAdminUsers:int parm: NVreg_PreserveVideoMemoryAllocations:int parm: NVreg_EnableS0ixPowerManagement:int parm: NVreg_S0ixPowerManagementVideoMemoryThreshold:int parm: NVreg_DynamicPowerManagement:int parm: NVreg_DynamicPowerManagementVideoMemoryThreshold:int parm: NVreg_EnableGpuFirmware:int parm: NVreg_EnableUserNUMAManagement:int parm: NVreg_MemoryPoolSize:int parm: NVreg_KMallocHeapMaxSize:int parm: NVreg_VMallocHeapMaxSize:int parm: NVreg_IgnoreMMIOCheck:int parm: NVreg_NvLinkDisable:int parm: NVreg_EnablePCIERelaxedOrderingMode:int parm: NVreg_RegisterPCIDriver:int parm: NVreg_RegistryDwords:charp parm: NVreg_RegistryDwordsPerDevice:charp parm: NVreg_RmMsg:charp parm: NVreg_GpuBlacklist:charp parm: NVreg_TemporaryFilePath:charp parm: NVreg_ExcludedGpus:charp parm: rm_firmware_active:charp
安装完查看信息

看到GPU1，没有运行程序一直占用29%，经过查询需要驱动模式设置为常驻内存，默认状态是驱动每次用完都自动卸载的，然后重新加载。
