Installing Nvidia drivers on rhel 8.6 with dkms but getting asm/kmap_types.h and drm/drmP.h errors in build
When you encounter errors related to missing headers like `asm/kmap_types.h` and `drm/drmP.h` while building NVIDIA drivers with DKMS on RHEL 8.6, it typically means that your system is missing certain kernel development headers and libraries that are required for building kernel modules. You can resolve this issue by installing the necessary kernel development packages. Here's how to do it: 1. **Install Kernel Headers and Development Tools**: - Open a terminal on your RHEL system. - Use `yum` to install the kernel headers and development tools: ```bash sudo yum install kernel-headers kernel-devel ``` - You may also need to install other development tools and libraries to ensure a successful build: ```bash sudo yum groupinstall "Development Tools" ``` 2. **Rebuild the NVIDIA Driver**: - After installing the required packages, navigate to the directory where the NVIDIA driver source code is located. - Rebuild the NVIDIA driver
