Bug Report

nvidia-current-open 550.163.01 fails to build against kernel headers 6.12.100+deb13-common (Debian trixie-security), while building successfully against 6.12.96+deb13-amd64 and earlier point releases.

Build error:

nv-pci.c: In function ‘nv_resize_pcie_bars’:
nv-pci.c:237:9: error: too few arguments to function ‘pci_resize_resource’
  237 |     r = pci_resize_resource(pci_dev, NV_GPU_BAR1, requested_size);
      |         ^~~~~~~~~~~~~~~~~~~
include/linux/pci.h:1421:18: note: declared here
 1421 | int __must_check pci_resize_resource(struct pci_dev *dev, int i, int size,
      |                  ^~~~~~~~~~~~~~~~~~~

Apparently, the kernel's pci_resize_resource() now takes an additional argument compared to previous 6.12.x releases.

System info:

• Distro: Debian 13 (trixie)
• Kernel headers: linux-headers-6.12.100+deb13-common, version 6.12.100-1
• Driver: nvidia-current-open 550.163.01
• Last known working kernel: 6.12.96+deb13-amd64

Steps to reproduce:

1. Install linux-headers-6.12.100+deb13-* on Debian trixie
2. DKMS attempts automatic rebuild of nvidia-current-open
3. Build fails as above

Full build log attached.

Start with nv-pci.c at nv_resize_pcie_bars and compare its pci_resize_resource call with the signature in include/linux/pci.h for linux-headers-6.12.100+deb13-common. Reproduce the DKMS build using the attached make.log context and verify that nvidia-current-open 550.163.01 builds successfully against the affected headers while retaining compatibility with the last known working 6.12.96 headers.
