More Info

Describe the bug:
The NVIDIA open-source driver (version 570.153.02) fails to compile against Linux kernel 6.15.1-surface-2 due to an error in nvidia-uvm/uvm_pmm_gpu.c. The compiler reports that struct page has no member named pgmap, used in the page_pgmap macro. This occurs in the uvm_pmm_gpu_device_p2p_init and uvm_pmm_gpu_device_p2p_deinit functions, specifically at lines 3332 and 3347 of uvm_pmm_gpu.c. The issue appears to be related to changes in the kernel's struct page definition, possibly specific to the surface-2 kernel variant.

Steps to reproduce:

1. Install Linux kernel 6.15.1-surface-2
2. Install NVIDIA open-source driver version 570.153.02 via DKMS or package manager.
3. Attempt to build the driver module using:

   sudo dkms build -m nvidia -v 570.153.02
   
   

Compilation fails with the error:
nvidia-uvm/uvm_linux.h:429:32: error: ‘struct page’ has no member named ‘pgmap’

Start with nvidia-uvm/uvm_linux.h around the page_pgmap macro and nvidia-uvm/uvm_pmm_gpu.c at uvm_pmm_gpu_device_p2p_init and uvm_pmm_gpu_device_p2p_deinit. Reproduce the DKMS build against Linux 6.15.1-surface-2 headers and compare the affected struct page usage. Done means the 570.153.02 module builds successfully against the reported kernel.
