根据官网文档编译更新两个.dtb文件之后，用ethtool可以看到4个mgbex_0口显示速度都是25000Mb/s，但是却发现nvpmodel执行失败，提示如下：
$ sudo nvpmodel -q
NVPM WARN: power mode is not set!
$ sudo nvpmodel -m 1
NVPM ERROR: Failed to determine the driver of GPU, assuming nvgpu.NVPM ERROR: Error opening /sys/bus/pci/devices/0000:01:00.0/gpu_pg_mask: 2
NVPM ERROR: optMask is 1, no request for power mode
$
刷机命令： sudo ./l4t_initrd_flash.sh jetson-agx-thor-devkit internal
刷机之后，没有进行其他配置或者安装。
参考文档：
Are you sure this issue only happened after you update the dtb but not actually already there before your modification?
我尝试了两种方式给Thor刷机：
1.用sdkmanager刷机。该方法刷机后nvpmodel是正常的，但25G的修改无效。
2.用命令行刷机。sudo ./l4t_initrd_flash.sh jetson-agx-thor-devkit internal 使能25G是有效的，但nvpmodel异常。命令行刷机的前置命令如下：
tar xf Jetson_Linux_R38.2.1_aarch64.tbz2
sudo tar xpf Tegra_Linux_Sample-Root-Filesystem_R38.2.1_aarch64.tbz2 -C Linux_for_Tegra/rootfs/
cd Linux_for_Tegra
sudo ./tools/l4t_flash_prerequisites.sh
sudo ./apply_binaries.sh
cd -
sudo cp tegra264-p4071-0000+p3834-0008-nv.dtb Linux_for_Tegra/kernel/dtb/
sudo cp tegra264-p4071-0000+p3834-0008-nv.dtb Linux_for_Tegra/bootloader/

sudo cp tegra264-bpmp-3834-0008-4071-xxxx.dtb Linux_for_Tegra/bootloader/
cd Linux_for_Tegra
sudo ./tools/l4t_create_default_user.sh -u ictrek -p ictrek -a
what is the result of lspci after you enabled the 25GB?
Please check the file for full pci info. Thanks

Your gpu driver is gone from the lspci.
Share your full dmesg too.
因为项目安排的原因，暂时没有拿到开发套件上的dmesg，我另外从一个自研载板+T5000的环境上保存了dmesg，这里面所做的改动是仅使能了pcie C3，没有使能25G。这里同样有nvpmodel失败的问题，和开发套件上使能25G之后是一样的情况。请帮忙看下可否参考，谢谢！

What is the result of lspci on this board?
重建了软件环境Linux_for_Tegra/，除了“sudo ./tools/l4t_create_default_user.sh -u ictrek -p ictrek -a”之外不做任何改动，然后用“sudo ./l4t_initrd_flash.sh jetson-agx-thor-devkit internal”刷到 自研载板+T5000 的环境上，面临同样的nvpmodel错误。

另外附上dmesg信息：

感谢提供线索！我会尝试一下看是否有效。
能否提供一下这个文档的链接？我在devkit和developer的guide里都没搜到，谢谢！
3. Apply the binaries based on the platform: Thor
sudo ./apply_binaries.sh --openrm
Thanks very much!
加了这个参数之后，用命令行刷机确实解决了nvpmodel的异常，而且用gpu_gurn能跑起来压力测试。
感谢指点！
但是还遗留了一个gpu相关问题：查看gpu温度时报错如下，其它几个温度都能正常查看。各位高手见过这个情况吗？

Hi,hyla_huang1
The previous NVIDIA engineer told me about it, and then I found it in the JetPack 7.0 release note document.
Thanks！

If you want to see all values
grep -r "" /sys/class/thermal/thermal_zone*/* -d skip -I
or
find /sys/class/thermal/thermal_zone*/ -maxdepth 1 -type f -exec grep -H "" {} +
I encountered the same behavior
